Description
Technical field
The invention belongs to polyurethane product technical fields, and in particular to a kind of super soft sponge of polyurethane and its preparation side
Method.
Background technique
The super soft sponge sold currently on the market has that easily-deformable, comfort level is poor.Patent CN
102108117B discloses a kind of preparation method of super soft low-density sponge, by the polyethers of 100 parts by weight and 55~65 weight
The toluene di-isocyanate(TDI) of part is delivered in mixing head as raw material, then the chemistry hair of 4~5 parts by weight is added in mixing head
The foam stabiliser of infusion, the kicker of 0.4~0.6 parts by weight and 2~3 parts by weight stirs 5 under 20~25 DEG C of environment
~10 minutes；By the raw material uniformly mixed through pipeline in overflow launder into vacuum airtight container, in negative pressure of vacuum
In the environment of carry out foamable reaction；The mixed raw material that will be flowed out in overflow launder is conveyed by conveyer belt and is foamed, in blowing temperature 60
It is kept for 3~5 minutes under the conditions of~130 DEG C, can be prepared by the sponge of super soft low-density.Obtained sponge under vacuum conditions
Hardness and density are lower, using water as chemical foaming agent in foaming process, reduce the pollution to environment.The preparation
Method, it is necessary to which foaming is carried out under negative pressure of vacuum environment could obtain required product, and at high cost, reaction condition is harsher, difficult
To meet the needs of large-scale industrial production.
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of super soft sponge of polyurethane, have it is super soft,
The characteristics of good hand touch is not easy to tear, be unlikely to deform, antibacterial deodourizing；Present invention simultaneously provides preparation method, processing technology letters
It is single, high production efficiency.
The super soft sponge of polyurethane of the present invention, is made of, based on parts by weight, raw material is such as component A and B component
Under:
Component A:
B component:
Modified black 35~65 parts of material 100LL.
Wherein:
The polyether polyol DEP-330N is 3 degrees of functionality, the polyether polyol of molecular weight 4800；The polyethers is by Zibo
The federal chemical Industrial Co., Ltd's production of moral letter, the product surface skinning made of this kind of polyalcohol is good, and demoulding time is fast etc..
The polyether polyol DEP-505S is 3 degrees of functionality, the polyether polyol of molecular weight 3500；The polyethers is by Zibo
The federal chemical Industrial Co., Ltd's production of moral letter, EO content is high, the product good hand touch made of this kind of polyalcohol, softness etc..
The foam stabiliser is foam stabiliser Y-10366；The foam stabiliser Y-10366 for stepping figure production, has
Stable foam adjusts abscess and emulsifies the effect of foam material.
The physical blowing agent is methylene chloride；Part water can be replaced to reduce sponge density, reduce the use of black material
Amount.
The amine catalyst is amine catalyst A33, and the A33 of gas chemical products company of U.S. production mainly utilizes it
High activity, stronger catalytic action is played to gel reaction and foamable reaction.
The preparation method of the super soft sponge of polyurethane of the present invention, steps are as follows:
Component A is added in blender, 25 ± 2 DEG C of constant material temperature is adjusted, adjusts agitator speed to 4000~4500r/
Each raw material is uniformly mixed by min；The B component for being preheated to 25 ± 2 DEG C is poured into 4~5s of stirring in the component A of mixing, by mixture
Material pours into the mold for being preheated to 40 ± 5 DEG C, demoulds after 5~10min, obtains product.
Compared with prior art, beneficial effects of the present invention are as follows:
(1) complex role between each component of the present invention, the super soft sponge of preparation have super soft, and good hand touch is not easy to tear,
It is unlikely to deform, the advantages that antibacterial deodourizing.
(2) preparation method of the present invention, processing technology is simple, high production efficiency.
