Abstract

The invention discloses an acrylate thermal polymerization resin and a preparation method thereof. The preparation method of acrylate thermal polymerization resin comprises the steps of putting an acrylate monomer into a reaction container, adding a thermal initiator in an inert gas atmosphere, heating to 110-150 DEG C, reacting for 4-5 hours to obtain an acrylate polymer, adding hydroxypropyl acrylate or 2-ethylhexyl acrylate to adjust the viscosity of the system, and obtaining the acrylate thermal polymerization resin. The acrylate thermal polymerization resin provided by the invention is strong in viscous force and good in adhesive force, is free of a solvent process, can solve the problem of a solvent for synthesizing an existing solvent type pressure-sensitive adhesive, and can fill the vacancy of a low-TG-point solvent-free type pressure-sensitive adhesive on the market.

Description

technical field [0001] The invention belongs to the technical field of pressure-sensitive adhesives, and in particular relates to an acrylate thermopolymerization resin and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is a kind of adhesive, which is a kind of adhesive that is sensitive to pressure. It only needs to apply a certain pressure to tightly bond with the adherend. It is often processed into adhesive tapes, labels or various Sheet products to apply. Among them, solvent-based acrylic pressure-sensitive adhesives are widely used in pressure-sensitive labels, packaging tapes, double-sided adhesives, etc. because of their strong adhesion, fast drying speed, water resistance, cold resistance, high temperature resistance, and high humidity resistance. The solvents of the type acrylate are mainly ethyl acetate and toluene, these solvents are poisonous, flammable and pollute the environment. In addition, acrylate monomers are als...
