Description

Renewable sponge shoe pad polyurethane binder and preparation method thereof
Technical field
The present invention relates to a kind of polyurethane adhesive and preparation method thereof.
Background technology
Renewable sponge, also known as the beautiful cotton of hypo, protects beautiful excellent foam, is to be glued discarded recovery sponge using special binding agent The extraordinary polymeric material made after conjunction.
Sponge has the pore passage structure opening in a large number, and the renewable sponge therefore made has splendid sucting wet air permeability, subtracts The characteristics such as shake, soft comfortable, can be used for making shoe pad, medicated cushion etc..
Renewable sponge preparation method：Pulverize first and reclaim sponge, add binding agent mix homogeneously, then pass to vapor Curing molding, final ripening is cut into slices.
Traditional moisture-cure polyurethane adhesive adopts toluene di-isocyanate(TDI) (TDI) and polyether polyol bi-component body System, cohesive force is stronger, but because TDI is volatile, there is penetrating odor, toxicity big, impact environment and production operation personnel With user of service's health.In addition two component adhesive is also existed and is asked using inconvenience, consuming man-hour, product quality stability difference etc. Topic.
In recent years, for the problem of bi-component sponge binding agent, many enterprises begin attempt to single-component moisture curing polyurethane Binding agent is used for the bonding of renewable sponge, and the main composition of binding agent is polyether polyol or PEPA modification diphenylmethyl Alkane diisocyanate.The prior art is described in Application No. 201210509899,201410013786.0, In 201410534381.1,201510430057.X and 201510946344.6 Chinese patent application, but it has all employed Machine stannum class or organo-bismuth class catalyst, have such problems as reaction acutely and reaction are uneven, be particularly applied to renewable sponge footwear During pad produces, easily there is the problems such as binding agent caking, cohesive force deviation.201110437309.3 patent application discloses ring Guarantor's type high intensity regenerated foam polyurethane binder and preparation using method, wherein catalyst be N- (dimethylaminoethyl) morpholine, One or more of 4- methoxyethyl morpholine or 2,2- dual-morpholinyl diethyl ether, there is also react to a certain extent acutely and Reaction problem of non-uniform, is applied to renewable sponge shoe pad and produces, and binding agent caking easily and is distributed in shoe pad, overall shoe pad Cohesive force deviation.
Therefore application in renewable sponge shoe pad for the monocomponent moisture cure binding agent receives certain restriction.
