Inorganic thermal insulation and decoration mortar and preparation method thereofTechnical field
The present invention relates to a kind of material of construction, particularly relate to a kind of mortar of exterior wall finish, more specifically relate to a kind of utilize light inorganic aggregate to make it play decoration function while also possess inorganic thermal insulation and decoration mortar of heat insulating effect and preparation method thereof.
Background technology
Decoration mortar last century Europe exterior wall finish system be widely used, instead of with the characteristic of its excellence the only selection that coating and face brick become finish coat.Its deadweight is lighter than face brick, add the security of outer wall structure of building, and can by selecting template, the instrument of different graphic, impose and drag, roll, scrape, turn round pressure, the different operating method such as to rub, metope is changed and the various patterns such as embossing, ripple, wood grain, can form the effect of multiple texture, color and texture, expressive force is enriched, artistic feeling is strong, more ideally can merge with physical environment, architectural style and historical sites.Although but prior art solves mortar accumulation of salt in the surface soil problem, improves endurance quality etc., does not have heat insulating effect, exterior-wall heat insulation and reducing energy consumption engineering also exist limitation.
Decoration mortar is not long in the history of China, but has above advantage because of it, within nearly 2 years, obtains at home and develops fast.Particularly country has formulated the development strategy of " low-carbon economy " now, and for reducing energy consumption, decreasing pollution, reduction discharge, for " low-carbon economy " makes contributions, fast-developing and that widespread use is novel dry powder decoration mortar is imperative.
Summary of the invention
Technology to be solved by this invention is in order to overcome the deficiency of above existence; there is provided a kind of and be cheaply suitable for inorganic thermal insulation and decoration mortar of large public building and covil construction and preparation method thereof; for gelling material with cement, flyash; take expanded and vitrified small ball as insulation light skeletal; mix multiple additives and pigment, make and have that heat insulating, hydrophobic nature are strong, the free of contamination inorganic thermal insulation and decoration mortar of fireproof environmental.
Technical scheme of the present invention: a kind of inorganic thermal insulation and decoration mortar, its component and weight content are:
Cement 180-220 part, flyash 40-60 part, sand 560-600 part,
Dry powder 50-70 part, light inorganic aggregate 70-100 part, wilkinite 3-9 part,
Wood fibre 4-8 part, hydrophober 2-7 part, accumulation of salt in the surface soil inhibitor 2-5 part,
Ether of cellulose 0.5-4 part, rubber powder 6-15 part, pigment 1-30 part.
Described light inorganic aggregate is that unit weight is less than 120kg/m3iI class expanded and vitrified small ball.Described cement is normal silicate 42.5 cement or white silicate 42.5 cement.Described flyash is I level or II level flyash.Described sand is through scouring, the natural sand of drying or quartz sand.Described pigment is iron oxide pigment.Described rubber powder is the redispersable latex powder of the one or more combination in the multipolymer of vinyl acetate and tertiary ethylene carbonate, ethene, acrylate.Described hydrophober is organosilicon moisture repellent.Described accumulation of salt in the surface soil inhibitor is a kind of Special Resin based powders being used for suppressing accumulation of salt in the surface soil phenomenon to produce.
The preparation method of inorganic thermal insulation and decoration mortar: first cement, flyash, sand, dry powder, wilkinite, wood fibre, hydrophober, accumulation of salt in the surface soil inhibitor, ether of cellulose, rubber powder and pigment are mixed, subsequently light inorganic aggregate is added, even by mechanically mixing again, i.e. obtained inorganic thermal insulation and decoration mortar.
The present invention compared with prior art has following beneficial effect: 1, by adding light inorganic aggregate, utilizes material itself to have the structure of internal porous, the advantage that unit weight is low, is used for reducing the deadweight of material, reduces the thermal conductivity of material, improves its thermal property.2, by adding the high molecular polymers such as hydrophober, accumulation of salt in the surface soil inhibitor, ether of cellulose, rubber powder, making mortar have certain flexibility, can ensure to there will not be when repeated deformation fatigure failure, produce crack.And mortar internal structure is changed, improves the effect of hole, micromolecular water vapour molecule can be made so freely to pass through, and macromolecular water molecules cannot be through, thus the hydrophobic function of reinforced mortar, suppress the phenomenon of the accumulation of salt in the surface soil.3, select inorganic oxide iron pigment to mix colours, ensure the strong not fugitive color of the color fastness of material.
The main performance index of inorganic thermal insulation and decoration mortar all detects according to JC/T1024-2007, and detected value sees the following form:
