Abstract

The invention belongs to the technical field of development of waterproof materials, and in particular relates to weather-resistant hot-melting type pressure-sensitive adhesive and a preparation method thereof. The weather-resistant hot-melting type pressure-sensitive adhesive consists of the following raw materials in percentage by mass: 56 to 80 percent of butyl rubber, 0.5 to 5 percent of hydroxy acrylic resin, 10 to 20 percent of a thickening agent, 3 to 12 percent of a plasticizer, 0.1 to 3 percent of a silane coupling agent, 0.1 to 2 percent of an antioxidant, and 0.5 to 2 percent of an ultraviolet resisting agent. The weather-resistant hot-melting type pressure-sensitive adhesive has high adhesion property and also has excellent ageing resistance and ultraviolet resistance. Meanwhile, the problem that the butyl rubber and other components are separated due to the butyl rubber is not dissolvable in other components is solved by introducing the coupling agent and the hydroxy acrylic resin. The technical bottleneck that the weather resistance of the product is prolonged only by an ultraviolet additive and an anti-ageing agent because the main raw materials of the traditional hot melt adhesive product have low ultraviolet resistance is broken through. The phenomenon that the life of the product is shortened after the functions of the ultraviolet resisting agent and the anti-ageing agent are attenuated is avoided.

Description

technical field [0001] The invention belongs to the technical field of waterproof material development, and specifically relates to a weather-resistant hot-melt pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure sensitive adhesive (PSA) refers to a type of adhesive that is sensitive to pressure and can be bonded to the adherend with a little pressure on the finger, without the use of solvents or other auxiliary means. Hot-melt pressure-sensitive adhesive is the third-generation pressure-sensitive adhesive product after solvent-based and emulsion-based pressure-sensitive adhesives. Compared with the previous two, hot-melt pressure-sensitive adhesive has no solvent, which is more conducive to environmental protection and safe production, and has high production efficiency. , the production cost is relatively low, so countries around the world are vigorously developing hot-melt pressure-sensitive adhesives. [0003] At present,...
