Description

technical field [0001] The invention relates to a mold-proof and antibacterial polyurethane sponge and a processing method thereof. Background technique [0002] In today's life, polyurethane products account for an increasing proportion of people's lives. Polyurethane sponge (PU) is widely used as a kind of polyurethane products. It is mainly divided into polyester And polyether type, subdivided into ordinary sponge series, shock absorber breathable, breathable impermeable crust sponge, slow rebound sponge series, injection molding sponge series, craft sponge series, antistatic sponge, flame retardant sponge and so on. Because the sponge (PU) has good properties such as heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static, and air permeability. Products are widely used in clothing, home textiles, shoes and hats, toys, furniture, children's products, pet products, product packaging, etc. If sponge products are stored in a hu...
