Abstract

The invention relates to the technical field of waterproof adhesives, in particular to a preparation method of a waterproof adhesive, which comprises the following components: epoxy resin, an epoxy resin curing agent, an emulsifier, a pH value regulator, an anti-mildew antibacterial agent, an anti-aging agent, an anti-freezing agent, a plasticizer, a defoaming agent and a dispersing agent. The nano-silver, nano-salt and graphene are adopted to achieve mildew-proof and antibacterial effects, the problem that mildew and bacterium breeding are prone to occurring in water or a humid environment after use is solved, use sanitation and bonding performance are effectively guaranteed, calcium lignosulphonate and ethylene glycol are matched to achieve an anti-freezing effect, the problem that use is affected by freezing in a low-temperature environment is avoided, the bentonite, the silica powder and the silica wax are matched to achieve a waterproof effect, and the overall waterproof performance is effectively improved.

Description

technical field [0001] The invention relates to the technical field of waterproof adhesives, in particular to a preparation method of waterproof adhesives. Background technique [0002] Adhesive is one of the most important auxiliary materials. It is a viscous substance that connects two separated materials with the help of its viscous ability. It is widely used in many fields such as home decoration, wood, and electronic appliances. [0003] However, the adhesives currently on the market are prone to mildew and bacteria breeding when exposed to water or in a humid environment. On the one hand, the adhesive performance of the adhesive is affected, and on the other hand, the hygiene and aesthetics are poor. Freezing affects use. Therefore, those skilled in the art provide a method for preparing a waterproof adhesive to solve the problems raised in the above-mentioned background technology. Contents of the invention [0004] The object of the present invention is to provid...
