[0003] For example, Chinese patent CN106281151A discloses a hot-melt adhesive for polymer waterproof coils and a preparation method thereof. The hot-melt adhesive uses polyisobutylene, SBS, SIS, styrene-butadiene rubber, and butyl rubber as rubber base materials, and then adds a tackifier Resin, mineral oil, anti-aging agent and light stabilizer are prepared as additives. Although the hot melt adhesive is compounded with various rubber base materials, the heat resistance, bonding strength, and UV resistance of the hot melt adhesive are improved. performance, but its raw material composition is complex, and the cold resistance, water resistance, bond strength, volatility and other properties of the hot melt adhesive still cannot meet the higher requirements for use

Abstract

The invention relates to the technical field of chemical modification high polymer materials, and in particular to a hot melt adhesive for waterproof roll and a preparation method of the hot melt adhesive. The hot melt adhesive is prepared from the following components in parts by weight: 50-200 parts of butadiene styrene rubber, 200-300 parts of benzene alkene thermoplastic elastomer rubber, 200-300 parts of tackifying resin, 5-20 parts of an antioxidant, 5-20 parts of an ultraviolet light absorbent, 0-200 parts of naphthenic oil, 0-200 parts of base oil and 100-200 parts of polyisobutene, wherein the tackifying resin is one or any combination of petroleum resin, hydrocarbon resin and monomer resin. As the butadiene styrene rubber and the benzene alkene thermoplastic elastomer rubber are compounded as a rubber matrix, the hot melt adhesive is high in compatibility; due to addition of the petroleum resin, the hydrocarbon resin and the monomer resin as the tackifying resin, the initial adhesion, the cold resistance, the thermal stability and the adhesion strength of the hot melt adhesive can be improved, the volatility of the hot melt adhesive is reduced, and particularly the adhesion property of the hot melt adhesive in damp building environments such as cement, concrete and big sand can be improved.

Description

technical field [0001] The invention relates to the technical field of chemically modified polymer materials, in particular to a hot melt adhesive for waterproof coiled material and a preparation method thereof. Background technique [0002] Building waterproofing is a special measure taken to ensure that certain parts of buildings or structures are not corroded by rainwater, groundwater, domestic water and moisture in the air, and plays an important role in the entire construction project. The quality of building waterproof materials directly affects the normal use and life of buildings and structures. In the early 20th century, foreign building waterproofing materials were mainly linoleum, and paper-based linoleum was gradually replaced by glass fiber linoleum. With the significant development of the chemical industry, especially the rubber industry, many resins and rubbers suitable for building waterproof materials have been developed and produced, which has made the res...
