Abstract

The invention discloses polyurethane sponge and a processing method thereof. Polyether polyol with a flame retardant function is directly added to a material A, and a diethyl ethylphosphonate fire retardant is selectively added to a material B, so that the polyurethane sponge does not contain halogen, is low in viscosity and very stable in a two-component system of the material A and the material B, and a product is endowed with good fireproof and flame-retardant properties while the process is simple. The product is endowed with good mildew-proof and antibacterial effects through an antibacterial agent and a mildew preventive added to the material B; and through addition of nanoscale inorganic material tourmaline powder, the product has the function of lastingly emitting anions. The production technology and the formula are relatively simple on the premise that all performance indexes reach the expected requirements; the production process and the formula are relatively simple; the processes such as heating or refrigerating do not need to be specifically carried out in the production process and foaming and curing in a natural state can be carried out; the production success rate of sample post-detection is very high; the produced polyurethane sponge has obvious fireproof and flame-retardant functions, antibacterial and anti-mildew functions and continuous anion release function, and is beneficial to improvement of the competitiveness of the product.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyurethane sponge and a processing method thereof. Background technique [0002] The full name of polyurethane in Chinese is polyurethane, referred to as polyurethane. According to the physical properties of the product, it can be divided into polyurethane rigid foam, polyurethane soft foam, PU self-skinned sponge, etc., and the formula can be modified during production to obtain different density, elasticity and rigidity. and other physical properties. Among them, polyurethane soft foam is what we often call polyurethane sponge. According to the degree of softness and hardness, that is, the load resistance performance, polyurethane sponge foam can be divided into ordinary soft foam, super soft foam, high load-bearing soft foam, and high resilience soft foam. Wait. Compared with the expensive price of natural latex products, polyurethane sponge is wide...
