Abstract
The present invention relates to a formula of an anti-aging polyurethane sole material, wherein the formula comprises the following components, by mass: 35-50% of a polyol, 4-9% of a chain extender, 0.03-2% of a catalyst, 0.09-0.5% of a foaming agent, 0.05-2% of a foam stabilizer, 2-8% of a plasticizer, 35-50% of a prepolymer, 0.5-3% of nanometer TiO2, and 1-5% of gas phase white carbon black. According to the present invention, the used nanometer TiO2 provides strong absorption for ultraviolet ray, the Ti02 provides a good effect for improvement of photoaging resistance of the polyurethane material, and the white carbon black adopted as a nano-scale reinforcing filler with an excellent performance can be provided for improving an anti-aging performance and thermal stability of the polyurethane material, such that the prepared polyurethane sole material has a good anti-aging performance.
Description
Technical field:
The present invention relates to a kind of material for sole of shoe technical field, more specifically to a kind of ageing-resistant polyurethane sole materials.
Background technology:
The kind of material for sole of shoe is a lot, generally is divided into two kinds of natural class material for sole of shoe and synthetic class material for sole of shoe.Natural class material for sole of shoe comprises natural bottom leather, bamboo and wood material etc., and synthetic class material for sole of shoe comprises rubber, ethylene vinyl acetate EVA, polyurethane PU, polyvinylchloride etc.That the common characteristic of material for sole of shoe possesses is wear-resisting, water-fast, good springiness, be fit to not yielding etc. condition after pin type, the typing easily.At present synthetic class material for sole of shoe is a most widely used class footwear material.
Polyurethane sole materials is a kind of as synthetic footwear material, because its light wear-resisting, good springiness, anti-skidding oil resistant, characteristics such as comfortable and easy to wear more and more are subjected to consumers in general's welcome.But polyurethane sole materials is under effects such as illumination, oxygen, temperature, chemical mediator, biological activity medium, cause the change of material surface or material physical chemistry character and mechanical property easily, finally lose original good use properties gradually, cause the ageing failure of material.This is a kind of irreversible physics, chemical transformation.This aging life-span that has greatly influenced polyurethane sole materials.Therefore, need carry out modification to polyurethane material and handle to improve its ageing-resistant performance.
Summary of the invention:
The object of the present invention is to provide a kind of can effectively ageing-resistant polyurethane sole materials.
The present invention is achieved by the following technical solutions:
A kind of weather-resistant pu material for sole of shoe by weight percentage, comprises following component:
Preferred as technique scheme, described polyvalent alcohol is one or both in polyether glycol, the polyester polyol.
Preferred as technique scheme, described chainextender is ethylene glycol, 1, one or more in 4-butyleneglycol, the glycerine.
Preferred as technique scheme, described catalyzer is one or more in morpholine, triethylamine, the triethylene diamine.
Preferred as technique scheme, described whipping agent is water.
Preferred as technique scheme, described foam stabilizer is one or both in polydimethylsiloxane, the polyether-modified polysiloxane.
Preferred as technique scheme, described softening agent is one or both in phthalic acid dimethoxy glycol ester, the phthalic acid dipropylene glycol ester.
The present invention has following beneficial effect:
Nano TiO 2 has strong absorbent energy, Ti0 to ultraviolet ray
2Raising to the macromolecular material resistance to deterioration has effect preferably.White carbon black can improve ageing-resistant performance and the thermostability of polyurethane material as a kind of nano level reinforced filling of excellent performance.Therefore, the present invention is by adding nano-TiO
2Can improve the ageing-resistant performance of material well with white carbon black, thereby improve the work-ing life of material for sole of shoe.
