Abstract

The invention discloses a bacteriostatic anti-mite sponge. The bacteriostatic anti-mite sponge is generated by foaming of a mixture comprising the following materials: polyhydric alcohols including polyether polyol, polymer polyol and polyester polyol; and nanometer zinc oxide with a particle size in a range of 1 nanometer to 100 nanometers, wherein 0.1 part to 10 parts of the nanometer zinc oxideis added into every 100 parts by mass of the polyhydric alcohol. According to the invention, the antibacterial zinc oxide is added into an emulsion for producing the sponge, so the breeding of bacteria such as mould can be inhibited, the purpose of blocking mite food chains is achieved, and a sponge product is capable of fundamentally preventing and inhibiting mites; through the combined reactionof various polyols, a catalyst, a modifier and the nanometer zinc oxide, the sponge has the characteristics of excellent insulation, static prevention and dust prevention, and has soft hand feeling.

Description

technical field [0001] The invention relates to the technical field of sponges, in particular to an antibacterial and anti-mite sponge and a preparation method thereof. Background technique [0002] Sponge is a porous material, mostly made of wood cellulose fibers or foamed plastic polymers. It has the characteristics of good air permeability, thermal insulation, sound absorption and shock absorption, flame retardant and antistatic, and is widely used in automobiles and furniture. , daily necessities, underwear and other products in the manufacturing of various fields. [0003] While bringing a lot of convenience to people's daily production and life, the porous nature of the sponge material also determines that it is easy to accumulate various dust and foreign matter. In a warm and humid environment, these dust and foreign matter are easy to breed bacteria or mites. , causing damage to human health. When people use sponge products, most of them can only reduce the bacteri...
