Abstract
The invention relates to a high-resilience sponge and a preparation process thereof and is mainly used in the fields of automobiles, cosmetics, underwear production industries and top grade furniture production industries. The high-resilience sponge is prepared from the following raw materials in parts by weight: ethylene-vinyl acetate, azodicarbonamide, dicumyl peroxide, polypropylene glycol and diphenylmethane diisocyanate. The high-resilience sponge has the functions of heat preservation, heat insulation, sound absorption, shock absorption, inflaming retardancy, static resistance, high resilience and the like, thereby improving the use property; the high-resilience sponge has the advantages of good applicability, stable quality, low cost and available raw materials; and the processing technique is simple.
Description
Technical field
The present invention relates to a kind of sponge, relate in particular to a kind of high recovery sponge and preparation technology thereof, be mainly used in automobile, makeup, underwear production and top-grade furniture production.
Background technology
Sponge has materials with function such as insulation, heat insulation, sound-absorbing, damping as a kind of, and its purposes is very extensive, is indispensable material in the modern manufacturing industry.But sponge of the prior art still has certain limitation on fire-retardant, anti-electrostatic, high resilience function, fail to satisfy people's production requirement.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, through a large amount of research with constantly explore, provide a kind of high recovery sponge, solved sponge in the prior art still has certain limitation on fire-retardant, anti-electrostatic, high resilience function problem.
Another object of the present invention is to provide a kind of preparation technology of high recovery sponge.
Technical scheme of the present invention is as follows:
Count ratio by following raw materials in parts by weight and be prepared from ethylene vinyl acetate: Cellmic C 121: dicumyl peroxide: polypropylene glycol: diphenylmethanediisocyanate=80-160: 30-70: 3-9: 80-160: 3-7.
Count ratio by following raw materials in parts by weight and be prepared from ethylene vinyl acetate: Cellmic C 121: dicumyl peroxide: polypropylene glycol: diphenylmethanediisocyanate=110: 45: 6: 100: 3.
Preparation technology of the present invention is as follows:
Above-mentioned raw materials is mixed by above-mentioned weight ratio, place mould to foam afterwards, closed pore is broken up with mechanical force in the foaming back, promptly.
Advantage of the present invention and beneficial effect are as follows:
The present invention has functions such as insulation, heat insulation, sound-absorbing, damping, fire-retardant, anti-electrostatic, high resilience, has improved use properties, and conformability is good, steady quality, cost are low, raw material sources are easy to get, and complete processing is simple.
