A kind of waterproof mortar impermeability test sealing materialTechnical field
The invention belongs to sealing material technical field, it is specifically related to a kind of waterproof mortar impermeability test sealing material.
Background technology
At present, using waterproof polymer mortar to ooze water problem to solve buildings crackle on the buildingss such as factory building, house, vault, warehouse, Ji Keng, the anti-permeability performance of waterproof mortar drastically influence its result of use. The waterproof mortar meeting service requirements to obtain, the anti-permeability performance test of waterproof mortar just seems particularly important. But under higher impermeability pressure, waterproof mortar carries out often there will be when water permeability resistance can be tested poorly sealed and affects the situation of test, seriously have impact on the test of anti-permeability performance. According to JC/T984-2011 " Polymer cement materials " standard-required, sealing material when impervious water is tested adopts melt paraffin, but paraffin sealing effect is not good, easily from the space infiltration of test specimen and examination film, often detected result can not truly reflect the water permeability resistance energy of waterproof mortar, and paraffin need to be heated to melt could use completely, especially containing multiple harmful substances such as benzene in paraffin, the process of heating for dissolving can go out objectionable impurities by pyrolytic decomposition, cause atmospheric pollution and harmful to human is healthy.
Summary of the invention
The object of the invention is to overcome prior art defect, it is provided that a kind of waterproof mortar impermeability test sealing material, and sealing material is not only easy to operate, and has good combination and sealing property with waterproof mortar surface, has good impervious water effect.
For achieving the above object, the present invention adopts following technical scheme:
A kind of waterproof mortar impermeability test sealing material, sealing material by industrial grease, nano material, waterproof gasket cement in proportion Homogeneous phase mixing and become, wherein, taking weight percent sum as 100%, industrial grease 40-50%, nano material 20-30%, surplus is waterproof gasket cement.
The one that described industrial grease is selected from general lubricant fat, long-acting lubricating grease and special greases, all can directly buy common commercially available prod.
The one that described nano material is selected from nano silicon oxide, nano-titanium oxide and nano tin dioxide, and size is 30-100nm, all can directly buy common commercially available prod.
Described waterproof gasket cement is selected from neutral waterproof gasket cement or acid waterproof gasket cement.
Waterproof mortar impermeability test sealing material of the present invention can effectively solve sealing problem, avoids test block and the infiltration of examination film edge place, and sealing material does not need heating, decreases the pollution of obnoxious flavour. It is strong, nonpoisonous and tasteless that it smears intensity height, good springiness, cementability, and brushing convenient, be easy to operation, it is possible to meet the requirement of test block sealing in the impervious water test of waterproof mortar. With the waterproof mortar test block after smearing sealing material of the present invention carry out waterproof mortar anti-permeability performance test time, mortar and die trial junction seepage problem when can effectively solve impermeability test, and simple to operate, reliability is strong.
Compared to the prior art, the useful effect of sealing material of the present invention:
1) the present invention cannot effectively realize the problem of waterproof test sealing and the Special seal material researched and developed mainly for sealing materials such as existing paraffin, effectively improves the stopping property between test block and die trial, and impermeability pressure can reach more than 1.6MPa.
2) sealing material of the present invention is mixed by three kinds of Material Physics, avoids obnoxious flavour that the sealing materials such as paraffin produce in thaw process to the injury of environment and human body, and easy to operate.
3) the waterproof mortar impermeability test sealing material of the present invention is remained sealing material and can reuse and without the need to any process, decrease the waste of material when test block being sealed.

Test block described in Fig. 2 is loaded the schematic diagram in die trial by Fig. 3.
Embodiment
In order to make the object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further details. It is to be understood that specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
In following embodiment, described neutral waterproof gasket cement selects neutral silicone structure sealant, reaches gluing Industrial Co., Ltd. purchased from Jiangmen city delight. Described acid waterproof gasket cement selects acid silicone glass cement, purchased from Baiyun District, Guangzhou City Yue Kai Viscose glue product factory.
Embodiment 1
A kind of waterproof mortar impermeability test sealing material, sealing material is made up of following materials by weight percentage: industrial grease 50%, nano material 30%, waterproof gasket cement 20%. Described industrial grease is long-acting lubricating grease; Described nano material is nano silicon oxide, and grain diameter is 30-100nm; Described waterproof gasket cement is neutral silicone structure sealant.
The preparation method of above-mentioned waterproof mortar impermeability test sealing material is specially: take above-mentioned three kinds of raw materials in proportion, disposable joins in container, fully stirs, mixes and get final product.
Embodiment 2
A kind of waterproof mortar impermeability test sealing material, sealing material is made up of following materials by weight percentage: industrial grease 45%, nano material 25%, waterproof gasket cement 30%. Described industrial grease is general lubricant fat; Described nano material is nano-titanium oxide, and grain diameter is 30-100nm; Described waterproof gasket cement is neutral silicone structure sealant.
The preparation method of above-mentioned waterproof mortar impermeability test sealing material is with reference to embodiment 1.
Embodiment 3
A kind of waterproof mortar impermeability test sealing material, sealing material is made up of following materials by weight percentage: industrial grease 40%, nano material 20%, waterproof gasket cement 40%. Described industrial grease is special greases; Described nano material is nano tin dioxide, and grain diameter is 30-100nm; Described waterproof gasket cement is acid silicone glass cement.
The preparation method of above-mentioned waterproof mortar impermeability test sealing material is with reference to embodiment 1.
As shown in Figure 1 to Figure 3, the concrete steps adopting sealing material of the present invention to carry out waterproof mortar impermeability test according to JC/T984-2011 " Polymer cement materials " standard are as follows:
Step one, is evenly applied in waterproof mortar test block 1 surface, smearing thickness 2-3mm by the sealing material 2 of the present invention;
Step 2, is pressed in impervious test mould 4 by the waterproof mortar test block 3 after smearing sealing material;
Step 3, at impervious test mould screw thread, skim industrial grease is evenly smeared at place, and when avoiding pressurizeing, water oozes out from screw thread, then and is tightened on the operator's console of Anti-leakage instrument by the waterproof mortar test block installation of band impervious test mould, opens Anti-leakage instrument and tests.
Find through test: sealing material of the present invention effectively improves the stopping property between waterproof mortar test block and impervious test mould, and impermeability pressure can reach more than 1.6MPa; And when carrying out impermeability test with paraffin, it is very difficult to solve the problem of waterproof test sealing, finally can not reflect the actual impervious ability of waterproof mortar test block.
