Abstract

The invention provides a waterproof anti-corrosion adhesive and belongs to the technical field of adhesives. The waterproof anti-corrosion adhesive is prepared from the following raw materials in parts by weight: 40-48 parts of trichloropropane, 25-30 parts of modified acrylic resin, 7-10 parts of waterproof agent, 12-16 parts of anti-corrosion agent, 5-8 parts of filler and 6-8 parts of auxiliaries. According to the waterproof anti-corrosion adhesive provided by the invention, the acrylic resin is modified and has a remarkable synergistic effect with the waterproof agent, the anti-corrosion agent, the filler and the auxiliaries; through organic combination of the materials, an adhesive for ceramic materials is prepared, which can improve the corrosion resistance and water resistance of the materials and has good mechanical property and aging resistance; with excellent comprehensive performance, the adhesive meets the bonding requirements of the ceramic materials such as glass and ceramic tiles, and has good bonding property and can be applied to a tough environment for long.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a waterproof and corrosion-resistant adhesive and a preparation method thereof. Background technique [0002] Ceramic materials such as glass and ceramic tiles are often used by bonding multiple pieces of glass or ceramic tiles together. Therefore, the performance of the adhesive will greatly affect the use effect of the later products, and ceramic products are often not It is not easy to bond firmly, so it will bring some unnecessary problems to the later use, and seriously affect the normal production and life. Moreover, ceramic materials need to have waterproof and corrosion-resistant effects during use. Traditional adhesives are prone to defects such as aging, cracking, and deformation after encountering water or acid-base corrosion. Therefore, it is of great significance to provide a binder with good bonding performance, which can bond ceramic materials together, and has ...
