Abstract
The invention relates to a formula used for the field of shoe materials, in particular to a memory sponge formula. According to the formula, a memory sponge is prepared from the following raw materials by weight: 51.3%-54% of polyether polyol; 43%-46% of diphenylmethane diisocyanate; and 2.6%-3% of an auxiliary agent. The memory sponge prepared according to the formula has weak temperature sensitivity, and its softness/hardness basically does not change with temperature variation or just has small changes. Therefore, when the memory sponge prepared by the formula is made into a shoe, the wearing space of the shoe is not influenced, so that the preparation cost cannot be increased and a wearer can be more comfortable.
Description
Technical field
The present invention relates to a kind of prescription that is used for footwear material field, specifically is a kind of memory sponge prescription; It is mainly used in the making of shoe-pad.
Background technology
In footwear material field, the material that is used to make is a lot, and the memory sponge is wherein a kind of.At present, the existing memory sponge that is used for the footwear material on the market, but existing memory sponge is stronger for the susceptibility of temperature, and strong soft or hard variation can take place along with temperature variation can not play temperature variation and soft or hard does not change or change very little purpose.This has a strong impact on the quality of making the footwear section product, can diminish because of memory sponge hardening internal space in winter like shoes, otherwise becomes big because of the deliquescing internal space summer.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of memory sponge prescription very weak to temperature sensitivity is provided.
The present invention realizes through following technical scheme,
A kind of memory sponge prescription is formed by the following feedstock production of percentage ratio meter by weight:
Polyether glycol 51.3%-54%
Diphenylmethanediisocyanate 43%-46%
Auxiliary 2.6%-3%.
As the further improvement of technique scheme, said W 166 is formed by the following feedstock production of percentage ratio meter by weight:
Polyether glycol 5613 30%-40%
Polyether glycol GLR2000 30%-40%
Polyether glycol 89796 20%-40%.
As the further improvement of technique scheme, said diphenylmethanediisocyanate is a diphenylmethanediisocyanate 6502.
As the further improvement of technique scheme, said auxiliary is formed by the following feedstock production of percentage ratio meter by weight:
Silicone surfactant L580 6.3%-10.83%
Amine type accelerator 0.93%-1.05%
Tin catalyst T-9 1.06%-2.1%
Pore-creating agent 1900 36.98%-42.11%
Black pigment PM928 26.37%-31.5%
Water 12.41%-17.54%
Preferably, said amine type accelerator is amine-ethylene glycol mixture.
Preferably, said tin catalyst T-9 is the sour inferior tin of good fortune.
Preferably, said pore-creating agent 1900 is one to be selected from the material in the following group: Vestolen PP 7052, vinyl alcohol.
Memory sponge prescription is processed the memory sponge through following operation:
1, premix is about to polyether glycol and auxiliary and pours that to carry out stirring at low speed in the foaming appearance tool even into;
2, high speed uniform mixing is poured polyether glycol and the adjuvant intermixture of stirring at low speed after evenly in the diphenylmethanediisocyanate into, and high speed is carried out uniform mixing then;
3, in the milky white stage, behind the high speed uniform mixing, the fs of reaction is operable time during this period of time, and time range is 5 ~ 30s, and this moment, blended liquid also had certain flowability;
4, foaming stages, the milky white stage has just entered into second step of reaction later, and the foamed time scope is 40 ~ 85s, and this stage mixing liquid is progressively become solid-state by liquid state, form foams, has certain support strength;
5, maturation stage, this stage time range at room temperature is 3 ~ 6d;
6, moulding, maturation stage be just fully slaking later, promptly molded memory sponge.
In above-mentioned operation, said auxiliary plays in whole foaming process and adds fast response, increases the foam surface flatness, makes foam perforate venting one's pent-up feelings and regulates the effect of foam color.
Through adopting the aforementioned techniques scheme, the invention has the beneficial effects as follows: the memory sponge that this invention is made since to temperature sensitivity very a little less than, its soft durometer does not change with variation of temperature basically or changes very little.Therefore, after the memory sponge that utilizes this prescription to make is processed footwear, can not influence the space of wearing of footwear, so that not only cost of manufacture can not increase, and make the wearer more comfortable.
