The adhesive is prepared from the following raw materials in parts by weight: 45-60 parts of modified hydroxyl acrylic resin, 1-5 parts of butanone, 2-7 parts of tri(2-chloroethyl)phosphate, 1-3 parts of p-tert-butylcatechol, 3-7 parts of dicyandiamide, 2-6 parts of vinyl triethoxysilane, 12-18 parts of talcum powder and 4-9 parts of modified aluminum hydroxide. The adhesive disclosed by the invention has excellent waterproof flame-retardant performances.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a waterproof and flame-retardant adhesive and a preparation method thereof. Background technique [0002] Adhesion refers to the technology in which the surfaces of homogenous or dissimilar objects are joined together with adhesives, which have the characteristics of continuous stress distribution, light weight, or sealing, and most process temperatures are low. Adhesive is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Adhesive has developed the fastest in modern times, has a wide range of application industries, and has a significant impact on the progress of high-tech science and technology and the improvement of people's daily life. Therefore, research, development and production of various types of adhesives are very important. The properties of the adhesive determine the extensivene...
