Abstract

The invention discloses a second component prepared on the basis of polyurethane degradation products for polyurethane plastic runways and application of the second component to preparing the plastic runways. The polyurethane degradation products are degradation products directly obtained by means of alcoholysis of scrap or waste of polyurethane elastomer products, polyether polyol can be replaced by the polyurethane degradation products, and the second component for the polyurethane plastic runways can be prepared from the polyurethane degradation products and substances such as vulcanizing agents and can be used for preparing the polyurethane plastic runways. The second component and the application have the advantages that a raw material, namely the waste of polyurethane elastomers, is easily available, the second component and the application are favorable for solving environmental protection problems due to industrial polyurethane waste, production processes are simple relatively, and the second component has a high economical benefit; the polyurethane plastic runways prepared by the aid of the second component for the polyurethane plastic runways are high in hardness, tensile strength and elongation at break, and accordingly the second component has extremely high popularization value.

Description

technical field [0001] The present invention relates to the field of recycling of polymer materials. Specifically, the present invention relates to the application of component B of a polyurethane plastic runway prepared based on polyurethane degradation products in the preparation of a plastic runway and the prepared plastic runway. Background technique [0002] The forms of polyurethane resin products include soft, semi-rigid and rigid foam plastics, elastomers, paint coatings, adhesives, sealants, synthetic leather coating resins, elastic fibers, etc., and are widely used in automobile manufacturing, refrigerator manufacturing, transportation, etc. Transportation, civil construction, footwear, synthetic leather, fabrics, electromechanical, petrochemical, mining machinery, aviation, medical, agriculture and many other fields, in order to protect resources and the environment, now vigorously advocate the recycling of various plastic products to achieve polyurethane The recy...
