Problems solved by technology

However, the flexibility of polyurethane foam is poor, which cannot meet the requirements in special industries. The surface of carbon fiber is hydrophilic, the surface has high activity, and good toughness, but the interface compatibility with other materials is poor, which reduces the foam to a certain extent. The mechanical and mechanical properties of plastics prevent the excellent properties of carbon fibers from being fully utilized. How to prepare a polyurethane foam with good toughness and excellent mechanical properties has become a technical problem that needs to be solved at present.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a modified polyurethane foamed plastic. Background technique [0002] Polyurethane foam is a good raw material, which is used in sofas, mattresses, shoe materials, high-end furniture and other fields, and plays an increasingly important role in the national economy. However, the flexibility of polyurethane foam is poor, which cannot meet the requirements in special industries. The surface of carbon fiber is hydrophilic, the surface has high activity, and good toughness, but the interface compatibility with other materials is poor, which reduces the foam to a certain extent. The mechanical and mechanical properties of plastics prevent the excellent properties of carbon fibers from being fully utilized. How to prepare a polyurethane foam with good toughness and excellent mechanical properties has become a technical problem that needs to be solved at present. Contents of the inve...
