Problems solved by technology

[0002] At present, in some enterprises in our country, a large amount of scraps are produced every year, such as the scraps of shoe uppers of shoe-making enterprises, the scraps of corners of packaging companies, etc. The materials of scraps are pure cotton fabrics, synthetic fiber fabrics, and fiber foam. Composite fabrics, flocking fabrics, artificial leather fabrics, non-woven fabrics, etc., the conventional treatment methods for the waste generated are electric incineration and landfill. The first incineration method needs to incinerate tens of thousands of tons at a time. equipment, not only cannot dispose of waste in time, the cost is high, but also pollutes the environment very seriously

preparation example Construction

[0037] The inventive method is based on the preparation method of the filling type soft polyurethane foam material of shoe upper leftover material, comprises the following steps:

[0038] Break the leftover material of the shoe upper into 1.0~10.0cm 2 According to the formula, weigh the scraps of shoe uppers, polyether polyols and other additives, put them in a container and mix them for 3-10 seconds, fill them into the mold, and cure them at 30°C for 10-30 minutes. After cooling, take out the product , to obtain filled flexible polyurethane foam.

[0039] The auxiliary agent refers to a chain extender, a foaming agent, and a catalyst.

[0040] The polyether polyol is one or more compounds of polyether diol, polyether triol, etc.;

[0041] The chain extender is one of ethylene glycol, ethylenediamine, 1,4-butanediol, diethylene glycol, etc.;

[0042] The foaming agent is one or more compounds of dichloromethane, HCFC-141b, water and the like.

[0043] The catalyst is one o...
