A kind of preparation method of the slow-resilience resin material for soleTechnical field:
The present invention relates to rosin products technical field, refer in particular to a kind of preparation method of the slow-resilience resin material for sole.
Background technology:
Resin material is widely used in daily life, along with the development of technology, has occurred the resin material with shape memory at present.So-called memory resin material is: be exactly that macromolecular material is endowed certain shape under certain condition, when external conditions changes, it can correspondingly change shape and be fixed, if outside atmosphere changes again with rule in a particular manner, shape memory high molecule material has just reversibly returned to primary state.The polymer that above-mentioned shape memory high molecule material major part uses is resin, is therefore called as memory resin.
The application of current memory resin is mainly that, with the related products of human body effect, such as pillow, back cushion etc., also can be used as the equipment of fixing wound site, is used for replacing traditional gypsum to stretch tight bundle.If but current memory resin also existing many deficiencies for making sole, comprising compressive property bad etc., being difficult to use on the product such as sole, shoe-pad.The present inventor, through constantly experiment, proposes following technical scheme.
Summary of the invention:
Technical problem to be solved by this invention is just the deficiency overcoming currently available products, provides a kind of preparation method that can be used for the slow-resilience resin material of sole.
In order to solve the problems of the technologies described above, present invention employs following technical proposals: this is used in the preparation method of low resilience resin material of sole, material is made up of A, B two kinds of raw materials, wherein A raw material is polyester polyol and pore-creating agent, B raw material is polymeric isocyanate, and A, B two kinds of raw materials according to its mol ratio of reacting are: A:B=1:1-5.
Furthermore, in technique scheme, composition and the weight proportion of described B raw material are as follows:
Polyester polyol 20-40%;
Isocyanic ester 60-80%;
The molecular weight of described polyester polyol is that 3000, B material composition making method is as follows: first, retort is heated to 80 DEG C, keeps at least 1 hours, makes it dry; Secondly, above-mentioned polyester polyol is added in retort by proportioning, and stirs, make the thermally equivalent of polyester polyol; Then, then add enter isocyanic ester in retort, fully stir, and the temperature of retort is controlled between 80 DEG C-100 DEG C, the after chemical reaction time, required A composition can be produced: polymeric isocyanate; Finally, before B raw material is put into bucket, be first filled with nitrogen to bucket, then 50 DEG C of A raw materials will be cooled to contain in bucket, and seal.
Furthermore, in technique scheme, composition and the weight proportion of described A raw material are as follows:
The making method of A raw material is as follows: first, retort is heated to 80 DEG C, keeps at least 1 hours, makes it dry; Secondly, add in retort by the polyester polyol of the different molecular weight in above-mentioned A raw material and pore-creating agent by proportioning component, stir, the temperature of retort controls between 80 DEG C-100 DEG C; Finally, after latter 50 DEG C of retort cooling, B material is loaded in bucket, material sealing.
Furthermore, in technique scheme, described pore-creating agent is silicone oil
Furthermore, in technique scheme, described A, B two kinds of raw materials are in retort during mix and blend, the rotating speed of retort is 120-150 rev/min, wherein the time of A raw material mix and blend is 60-120 minute, in B raw material, the churning time of polyester polyol is 20-40 minute, and the time of carrying out reacting after adding isocyanic ester is 2-3 hour.
Furthermore, in technique scheme, the polyester polyol that A, B two kinds of raw materials adopt is by hexanodioic acid, ethylene glycol, butyleneglycol reaction preparation.
Relative to prior art, the resin material prepared by the present invention is applied in sole product, has the following advantages:
1, there is stronger pulling force ' tear ' and the characteristic of the physicals aspect such as extension, be applied in sole, sole can be made to have good critical external compressive resistance performance, well can protect foot
2, made sole has effect that is wear-resisting and on-slip: this material does not injure skin, and anti-slip effect is fine, prevents the accidents such as tumble injury.
3, there is damping, energy-absorbing function: for the user, the discomfort that the weight that can alleviate self is brought to oneself pin joint or knee joint or pain, and some external impulsive contact forces can be absorbed, the sense of discomfort brought on foot can be reduced.
4, there is the effect of comfortable ventilating: material prepared by the present invention has micropore, good air permeable effect can be had for sole.
5, the material prepared due to the present invention has low resilience effect, and it can form good contact with sole as sole, forms omnibearing support to foot, has foot health promotion effect.
