Abstract
The invention provides a pore-forming agent for polyurethane elastomers and application of the pore-forming agent. The pore-forming agent contains polybutadiene and gaseous silicon dioxide, wherein the weight ratio of polybutadiene to gaseous silicon dioxide is 1:4 to 7:1. The pore-forming agent can be used for preparing porous polyurethane elastomers, and is particularly suitable for preparing porous polyurethane shoe soles. The porosity of the polyurethane shoe sole is effectively increased and the size stability of the shoe sole sample is improved, and besides, the tear resistance and wear resistance of the polyurethane shoe sole are improved. The production cost of polyurethane shoe soles is reduced actually and effectively.
Description
Technical field
The present invention relates to a kind of pore-creating agent for polyurethane elastomer.
Background technology
Polyurethane shoe-sole has that quality is light, good springiness, intensity height, oil resistant, the characteristic such as comfortable and easy to wear, but cost is also than the sole height of the material produce such as EVA, TPR.The compact density that reduces polyurethane shoe-sole is the effective ways that reduce the shoe sole production cost.Yet the low density sole easily shrinks, size is unstable, wear resistance and tear strength are relatively poor.In order to address these problems, people often add pore-creating agent in the process of producing low-density polyurethane soles, reduce the surface tension of polyurethane foam wall, impel abscess to break, and improve the percentage of open area of polyurethane shoe-sole, improve the problems such as sole shrink of product.
Pore-creating agent is the special tensio-active agent of a class, generally contains hydrophobicity and hydrophilic segment or group.The pore-creating agent main Types has silicone copolymers, polyamine compounds, lipid, hydrophilic wax dispenser etc., and these pore-creating agents make an addition in the urethane resin, can improve the percentage of open area of polyurethane shoe-sole, but effect is single, can't take into account wear resistance and tear strength.In order to guarantee the over-all properties of low density sole, often need to add anti-wear agent and softening agent etc., so that the production cost of polyurethane shoe-sole rises.
Liu Yijun write " the 511st page of urethane raw and auxiliary agent handbook (Chemical Industry Press) point out that polyhutadiene can be used as the pore-creating agent of polyurethane foam, and the urea that the disperse water foaming forms obtains the porous plastics of certain percentage of open area.But polyhutadiene need be dissolved in the polyether glycol in advance, and after the short period of time left standstill, polyhutadiene was separated from polyether glycol again, is difficult to make preferably polyurethane foam of quality.
