Description
Technical field
The present invention relates to polyurethanes technology fields more particularly to a kind of for manufacturing the combination material of polyurethane sole materials.
Background technique
Polyester polyurethane has preferable mechanical performance, and wear-resisting, intensity is good, and acid-proof alkaline is excellent；But polyester-type
The ester functional group of polyurethane encounters the water in air, is easy hydrolysis；In use, polyester type polyurethane material holds in wet environment
Degradable, relative molecular mass reduces, and molecular rearrangement causes tensile strength to weaken, and flexural property is deteriorated, and then causes using poly-
The sole cracking of ester type polyurethane material preparation, shortens sole service life, wastes material, lead to economic loss.
In the prior art in order to improve the hydrolytic resistance of PAUR material for sole, usually add in polyurethane shoe-sole
Add hydrolysis agent.But hydrolysis agent is at high price, limits its use scope；And hydrolysis agent can move to polyurethane
Sole surface layer, hydrolysis agent are unevenly distributed in polyurethane shoe-sole, influence the performance of hydrolysis agent performance.
Using polyester polyol as polyurethane sole materials made from raw material, due to wide with hardness range, wear-resisting, intensity
The excellent performances such as good, acid and alkali-resistance, have occupied a quarter in sole market at present.However the maximum defect of polyester polyurethane
Be that anti-hydrolytic performance is poor, in wet environment in use, be easy degradation and shorten the working life, cause waste of material with it is huge
Economic loss.
Currently, the most common approach of anti-hydrolytic performance for improving PAUR material for sole is addition hydrolysis agent,
But since hydrolysis agent is at high price, and surface layer can be moved to, limit its use scope.
