Abstract

The invention relates to slow recovery foam, belongs to the technical field of high polymer materials, and aims to solve the problems of poor folding endurance and high recovery deformation rate in the prior art. The slow recovery foam is mainly prepared from the following raw materials in parts by weight: 51 to 55 parts of polyether polyol, 55 to 60 parts of a hardening agent, 40 to 45 parts of slow recovery polyester, 70 to 80 parts of slow polyester, 20 to 23 parts of melamine, 30 to 35 parts of toluene diisocyanate, 5 to 8 parts of dichloromethane, 2 to 3 parts of water, 0.3 to 0.5 part of a first catalyst, 0.2 to 0.5 part of a second catalyst, 0.06 to 0.08 part of a foam stabilizer and 0 to 0.08 part of a coloring agent. The slow recovery foam has the effects of high folding endurance and low recovery deformation rate.

Description

technical field [0001] The invention relates to a slow rebound sponge, which belongs to the technical field of polymer materials. Background technique [0002] Sponge generally refers to foaming materials, and foamed products of resin, rubber, and plastic are called sponges. The polyurethane sponge is a foamed polyurethane material, which not only has the elasticity of rubber, but also has the strength of plastic and excellent processing performance, and can be used to prepare polyurethane slow rebound materials. Because of its porous honeycomb structure, it has excellent softness, elasticity, water absorption and water resistance, and is widely used in sofas, mattresses, flexible packaging and other industries. [0003] As one of the sponges, the slow-rebound sponge is mainly composed of polyurethane foam plastic, which has viscoelasticity and can be shaped according to body temperature and pressure, effectively reducing the pressure of the human body to zero pressure, off...
