High-performance hot-melt pressure-sensitive adhesive

Abstract

The invention discloses a high-performance hot-melt pressure-sensitive adhesive. The high-performance hot-melt pressure-sensitive adhesive comprises thermoplastic styrene-butadiene rubber, a tackifier, a plasticizer, a filler, an antioxidant and a coupling agent, wherein the tackifier is rosin modified phenolic resin; the plasticizer is di(2-ethyl hexyl) phthalate; the filler is quartz powder; the antioxidant is bis(3,5- tert-butyl-4-hydroxyl phenyl) thioether; and the coupling agent is aminopropyl triethoxy silane. The product is prepared by adopting five additives including the hermoplastic styrene-butadiene rubber, the tackifier, the plasticizer, the filler, the antioxidant and the coupling agent; and the prepared adhesive composition has characteristics of good stickiness, strong initial stickiness, environmental friendliness, high safety, high production efficiency and low production cost.

Description

technical field [0001] The invention relates to chemical products, in particular to a high-performance hot-melt pressure-sensitive adhesive. Background technique [0002] At present, there are different types of pressure-sensitive adhesives used in the market, and the fields of use are also different. There are various kinds of raw materials of pressure-sensitive adhesives currently used, and the functions they have are also different. Hot-melt pressure-sensitive adhesives are the third generation of pressure-sensitive adhesive products after solvent-based and emulsion-based pressure-sensitive adhesives. The raw materials used in current pressure-sensitive adhesives can no longer meet the needs of use during processing and production, especially in terms of viscosity, initial viscosity, In terms of environmental protection and safety performance, they cannot meet the needs of use, and block copolymers of styrene and isoprene are a new type of pressure-sensitive adhesive mat...

Problems solved by technology

Hot-melt pressure-sensitive adhesives are the third generation of pressure-sensitive adhesive products after solvent-based and emulsion-based pressure-sensitive adhesives. The raw materials used in current pressure-sensitive adhesives can no longer meet the needs of use during processing and production, especially in terms of viscosity, initial viscosity, In terms of environmental protection and safety performance, they cannot meet the needs of use, and block copolymers of styrene and isoprene are a new type of pressure-sensitive adhesive matrix. Although the performance meets the needs of various products, the production cost is extremely high. The production efficiency is relatively poor and does not conform to the business philosophy
