Adhesive for flame-retardant glass wool and preparation method of adhesive

Abstract

The invention provides an adhesive for flame-retardant glass wool and a preparation method of the adhesive. The adhesive contains the following raw materials in parts by weight: 50-70 parts of an acrylonitrile-butadiene-styrene copolymer, 35-50 parts of polyarylene ether nitrile, 18-30 parts of phenolic resin, 8-15 parts of ethylene-propylene-diene monomer, 6-12 parts of diethyl aminomalonate hydrochloride, 9-16 parts of an inorganic flame-retardant filler, 3-8 parts of epoxidized soybean oil, 6-13 parts of alumina fibers, 3-6 parts of a cosolvent, 4-8 parts of dimethylaminopropylamine, 7-16 parts of decabrominated dipheny ethane and 15-30 parts of n-butyl alcohol. The adhesive has good mechanical strength and flame retardance and further has good noninflammability due to a relatively highlimit oxygen index, added polyarylene ether nitrile and phenolic resin have great importance to the mechanical strength and flame retardance of the adhesive, and meanwhile, added alumina as a supportcarrier for a nano-filler has great importance to the flame retardance of the adhesive.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an adhesive for flame-retardant glass wool and a preparation method thereof. Background technique [0002] Glass wool belongs to a category of glass fibers and is a man-made inorganic fiber. Glass wool is a material made of molten glass fibrosis to form a cotton-like material. Its chemical composition belongs to glass and is an inorganic fiber. It has the advantages of good molding, small bulk density, low thermal conductivity, thermal insulation, good sound absorption performance, corrosion resistance, and stable chemical properties. In 1840, Britain first discovered that molten slag could be blown into fibers, and began to produce slag wool. In 1880, through research on the properties and uses of slag wool, Germany and the United States began to produce slag wool, and then it was used and produced in other countries. From 1930 to 1950, large-scale production an...

AI Technical Summary

Problems solved by technology

[0003] Glass wool needs adhesives to be bonded during the preparation process. Although glass wool has certain flame-retardant properties, most of the adhesives are based on rubber, plastics and other polymer materials. Therefore When applied to the production process of glass wool, it will inevitably affect the flame retardant performance of glass wool. Therefore, it has important application value to provide a high flame retardant adhesive applied to glass wool to improve the flame retardant performance of glass wool
