Abstract

The invention belongs to the technical field of polyurethane products and particularly relates to a polyurethane super soft sponge and a preparation method thereof. The super soft sponge is composed of a component A and a component B. The component A is prepared from, by weight, 40-70 parts of polyether polyol DEP-330N, 30-70 parts of polyether polyol DEP-505S, 1.5-2.5 parts of water, 0.5-0.9 part of foam stabilizer, 5-10 parts of physical foaming agents, 0.4-0.9 part of amine catalysts and 1-2 parts of color paste; the component B is prepared from, by weight, 35-65 parts of modified black material 100 LL. According to the polyurethane super soft sponge, all components act in a complex formulation mode, and the prepared super soft sponge has the advantages of being super soft, good in hand feeling, not prone to being torn, not prone to deformation, resistant to bacteria, resistant to odor and the like. The preparation method is simple in processing technology and high in production efficiency.

Description

Super soft sponge of urethane and preparation method thereof
Technical field
The invention belongs to polyurethane product technical field, be specifically related to super soft sponge of a kind of urethane and preparation method thereof.
Background technology
There is yielding, that comfort level is poor problem in the super soft sponge now commercially sold.Patent CN102108117B discloses a kind of preparation method of super soft low-density sponge, the tolylene diisocyanate of the polyethers of 100 weight parts and 55 ~ 65 weight parts is delivered in mixing head as starting material, in mixing head, add the suds-stabilizing agent of the chemical foaming agent of 4 ~ 5 weight parts, the kicker of 0.4 ~ 0.6 weight part and 2 ~ 3 weight parts again, stir 5 ~ 10 minutes under 20 ~ 25 DEG C of environment; By starting material good for Homogeneous phase mixing through Cemented filling in the overflow groove in vacuum airtight container, under the environment of negative pressure of vacuum, carry out foamable reaction; By the mixing raw material flowed out in overflow groove, foamed by tape transport, keep 3 ~ 5 minutes under blowing temperature 60 ~ 130 DEG C of conditions, the sponge of super soft low-density can be obtained.Sponge hardness obtained under vacuum and density all lower, using water as chemical foaming agent in foaming process, decrease the pollution to environment.Described preparation method, must carry out foaming under negative pressure of vacuum environment could obtain desired product, and cost is high, and reaction conditions is harsher, is difficult to the demand meeting large-scale industrial production.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide the super soft sponge of a kind of urethane, have super soft, good hand touch, not easily tears, not yielding, the feature of antibacterial deodourizing; The present invention provides its preparation method simultaneously, and complete processing is simple, and production efficiency is high.
The super soft sponge of urethane of the present invention, be made up of component A and B component, with weight parts, raw material is as follows:
Component A:
B component:
Black material 100LL35 ~ 65 part of modification.
Wherein:
Described polyether glycol DEP-330N is the polyether glycol of 3 functionality, molecular weight 4800; By Zibo moral, this polyethers believes that federal chemical Industrial Co., Ltd produces, the product surface skinning made of this kind of polyvalent alcohol is good, and demould time is fast.
Described polyether glycol DEP-505S is the polyether glycol of 3 functionality, molecular weight 3500; By Zibo moral, this polyethers believes that federal chemical Industrial Co., Ltd produces, EO content is high, the goods good hand touch made of this kind of polyvalent alcohol, soft etc.
Described suds-stabilizing agent is suds-stabilizing agent Y-10366; Step the suds-stabilizing agent Y-10366 that figure produces, there is stable foam, regulate the effect of abscess and emulsification foam material.
Described pneumatogen is methylene dichloride; Part water can be replaced to reduce sponge density, reduce the consumption of black material.
Described amine catalyst is amine catalyst A33, the A33 that aerification chemical product company of the U.S. produces, and mainly utilizes its high reactivity, plays stronger katalysis to gel reaction and foamable reaction.
The preparation method of the super soft sponge of urethane of the present invention, step is as follows:
Component A is added in agitator, adjust constant material temperature 25 ± 2 DEG C, regulate agitator speed to be mixed by each raw material to 4000 ~ 4500r/min; The B component being preheated to 25 ± 2 DEG C poured in the component A of mixing and stir 4 ~ 5s, poured into by mixture in the mould being preheated to 40 ± 5 DEG C, the demoulding after 5 ~ 10min, obtains product.
Compared with prior art, beneficial effect of the present invention is as follows:
(1) complex role between the present invention's each component, the super soft sponge of preparation has super soft, and good hand touch, not easily tears, not yielding, the advantages such as antibacterial deodourizing.
(2) preparation method of the present invention, complete processing is simple, and production efficiency is high.
