Problems solved by technology

[0004] However, when the existing starch fireproof boards are connected, they are rarely connected by screws and bolts, because this will affect the whole fireproof board, and when the fireproof board is damaged, the cost will increase virtually. Therefore, when the fireproof board is connected as a whole, generally is the use of adhesive
Because the main feature of the fireproof board is fireproof and high temperature resistance, the adhesive prepared by the existing preparation method cannot take into account the performance of fire resistance while maintaining high strength, which greatly limits the application range of the fireproof board

Abstract

The invention discloses a preparation method of an adhesive for fireproof board adhesion. The method comprises steps as follows: diethylene diamine, epoxy resin and diethlyeneglycol monobutylether react for 3-4 hours; after the reaction ends, vacuum pumping is performed for 15-20 min; allyl glycidyl ether is added, the mixture is kept at the constant temperature for 2.5-3 h and cooled to 75-82 DEG C, a VAE emulsion, water, vinyl ester resin and an activator are added, and the obtained mixture is kept at the constant temperature for 2-3 hours; a tackifier and a flame retardant are added, the mixture is stirred for 15-25 min, and the adhesive is obtained. The invention provides the preparation method of the adhesive for fireproof board adhesion. The adhesive prepared with the preparation method is applied to a fireproof board, has the same high-temperature-resistant and fireproof characteristics as the fireproof board and is high in adhesion strength; the preparation process is simple, requires mild conditions and little manual work and is low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a method for preparing an adhesive for bonding fireproof boards. Background technique [0002] Fire-resistant board, also known as fire-resistant board, is called thermosetting resin-impregnated paper high-pressure laminated board. It is a fire-resistant building material for surface decoration. It has rich surface colors, textures and special logistics properties. It is widely used in interior decoration, furniture, kitchen cabinets, Laboratory countertops, exterior walls and other fields. [0003] The fireproof board is a decorative board made of silicon or calcareous materials as the main raw material, mixed with a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives, and made by autoclaving. It is a new type of material that is more and more used at present, and its use is not only because of fire prevention factors. [0004] How...
