Special hot-melt pressure-sensitive adhesive for low-temperature waterproof coiled material butt-joint adhesive tape and preparation method thereof

Abstract

The invention relates to a special hot-melt pressure-sensitive adhesive for a low-temperature waterproof coiled material butt-joint adhesive tape and a preparation method thereof. The hot-melt pressure-sensitive adhesive comprises the following components in parts by weight: 50 to 60 parts of an SIS thermoplastic elastomer, 20 to 40 parts of a polyisobutylene compound, 5 to 10 parts of hydrogenated monomer resin, 10 to 15 parts of a tackifying resin compound, 1 to 2 parts of an antioxidant and 0.5 to 1.5 parts of an ultraviolet absorbent. Compared with the prior art, the hot-melt pressure-sensitive adhesive has the characteristics of high peel strength, good water resistance, and good low-temperature resistance, and can be widely applied to engineering construction of waterproof coiled materials.

Description

technical field [0001] The invention belongs to the technical field of hot-melt pressure-sensitive adhesives, and relates to a special hot-melt pressure-sensitive adhesive for low-temperature waterproof coiled tapes and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesives and their products have developed rapidly in the past two decades, and their applications have spread throughout various fields of the national economy and have entered thousands of households. However, in the application of basic research and technology development of pressure-sensitive adhesive products, There is still a big gap between China and developed countries. Some high-performance pressure-sensitive adhesive products still rely on imports from developed countries. Pressure-sensitive adhesives that can be used in the waterproof industry are only 0.2mm to 0.4mm thick in products, so the adhesive is required It must have strong cohesion to achieve the required bond...

[0002] Pressure-sensitive adhesives and their products have developed rapidly in the past two decades, and their applications have spread throughout various fields of the national economy and have entered thousands of households. However, in the application of basic research and technology development of pressure-sensitive adhesive products, There is still a big gap between China and developed countries. Some high-performance pressure-sensitive adhesive products still rely on imports from developed countries. Pressure-sensitive adhesives that can be used in the waterproof industry are only 0.2mm to 0.4mm thick in products, so the adhesive is required It must have a strong cohesion to achieve the required bonding strength. The hot melt pressure-sensitive adhesives currently prepared have problems such as insufficient adhesion to non-polar materials and other specific applications.
