Abstract

The invention discloses a hot-melting pressure-sensitive adhesive for PVC (Polyvinyl Chloride) plastic floor tiles, comprising the following components in parts by weight: 5-10 parts of thermoplastic elastomer SBS792, 20-25 parts of thermoplastic elastomer SIS4211, 5-10 parts of petroleum resin ESCOREZ5020, 20-30 parts of petroleum resin ESCOREZ1000, 15-20 parts of petroleum resin ESCOREZ5000, 10-15 parts of rubber softening oil KN4010 and 0.2-0.5 part of composite antioxidant. The invention also discloses a preparation method of the PVC hot-melting pressure-sensitive adhesive. The hot-melting pressure-sensitive adhesive has better cohesive force and better initial viscosity even in winter; compared with an imported product, the hot-melting pressure-sensitive adhesive has low price and properties completely meeting the requirements.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a hot-melt pressure-sensitive adhesive and a preparation method thereof, which are mainly used in the fields of PVC plastic floor tiles, nameplate bonding and the like. Background technique [0002] In recent years, due to the need for high-speed operation, reasonable coating, and the elimination of solvent pollution problems, hot-melt pressure-sensitive adhesive HMPSA has been developed. The main component of HMPSA is mostly styrene-based thermoplastic elastomer, which does not contain solvents and is pollution-free. Construction is carried out in a molten state, and after cooling and solidification, light finger pressure can be used to bond. It has a wide range of applications and can be used in sanitary materials, double-sided tapes, labels, packaging, medical and hygiene, book binding, surface protection films, wood and plastic processing, wallpaper and shoemak...
