Flame-retardant adhesive

Abstract

The invention discloses a flame-retardant adhesive. The flame-retardant adhesive is prepared from the following raw materials in parts by weight: 17 to 26 parts of aluminum oxide, 15 to 20 parts of halogen-free epoxy resin, 8 to 15 parts of ethyl 3-ethoxypropionate, 6 to 9 parts of alcohol soluble acrylic resin, 15 to 18 parts of an organic phosphorus compound, 3 to 6 parts of a curing promoter, 5to 8 parts of a flame retardant, 7 to 12 parts of a curing agent, 7 to 13 parts of a smoke suppressor and 4 to 9 parts of an ultraviolet absorbent. The flame-retardant adhesive is resistant to high temperature, good in flame-retardant effect, high in safety and stable in quality and contains a few of pollutants.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a flame-retardant adhesive. Background technique [0002] Adhesives are intermediates connecting two materials, mostly in the form of water agents, belonging to the category of fine chemicals, with a wide variety, mainly classified by adhesives, physical forms, hardening methods and adherend materials. Especially in the field of circuit boards, the adhesives used have high temperature requirements. The adhesives currently used have relatively single functions, poor flame retardancy, low reliability, and low safety performance. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a flame-retardant adhesive, which has high temperature resistance, good flame-retardant effect, high safety performance, less pollutants, and stable quality. [0004] In order to achieve the above object, the present invention prop...
