Emergency exit internal sound insulation sponge foaming adhesive

Abstract

The invention discloses an emergency exit internal sound insulation sponge foaming adhesive, and relates to the technical field of regenerated sponge. The emergency exit internal sound insulation sponge foaming adhesive comprises the following raw materials in parts by weight: 30-50 parts of a surfactant, 0.1-0.3 part of a defoaming agent, 2-8 parts of a dispersant, 2-6 parts of a cosolvent, 1-4 parts of a brightening agent and 6-8 parts of a flame retardant. The foaming adhesive is low in cost, the raw materials are environmentally friendly and non-toxic and free of pungent smell, the adhesive is convenient to store, not easy to cure and convenient to use and operate, the sponge produced by using the foaming adhesive is good in toughness, not easy to tear off and hard to combust due to addition of a great amount of flame retardant, a fire source can be effectively insulated, the fire hazard is avoided, a good sound insulation effect is achieved, and the adhesion strength is high.

Description

Technical field [0001] The invention relates to the technical field of sponges, in particular to a sound-proof sponge foam glue in a safety door. Background technique [0002] Sponge is a kind of porous material with good water absorption and can be used to clean things. The commonly used sponge is made of wood cellulose fiber or foamed plastic polymer. In addition, there are also natural sponges made of sponge animals. Most natural sponges are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (high-absorbent material without obvious pores) and poly Ester, sponge, is a new type of product. Its use value is no less than that of sponge. It is compressed and molded from sponge scraps, crushed, stirred, and steam sterilized at high temperature. Its price is low, which greatly reduces production costs. Its effect is good elasticity, good shape resi...

[0002] Sponge is a porous material with good water absorption and can be used to clean items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made of sponge animals. Most natural sponges are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material, no obvious pores) and polyvinyl alcohol. Ester, sponge, is a new type of product. Its use value is no less than that of sponge. It is formed by crushing sponge scraps, stirring glue, steam high-temperature sterilization and compression molding. Its price is low, which greatly reduces production costs. Its effect is that it has good elasticity, good resistance, and no peculiar smell. It can be made into products with various densities according to customer needs. This kind of recycled foam sponge is used in baby carriages. It needs to be used in the production of sponges. Foaming glue, the quality of foaming glue directly affects the quality of the sponge. The use of ordinary sponge foaming glue on the sponge will lead to weak bonding fastness, poor toughness and poor air permeability of the sponge.
