Abstract

The invention relates to the field of photocuring adhesives, in particular to a preparation method of a UV-curing adhesive for glass films. The method comprises the steps as follows: 1, preparing a liquid polyisoprene rubber graft; preparing a colorless and transparent optical liquid polyisoprene rubber prepolymer; uniformly mixing and stirring hydroxyl-terminated polydimethyl siloxane, methyl methacrylate and methanol; preparing a prepolymer; preparing a UV-curing adhesive to obtain the UV-curing adhesive for the glass films. After adoption of the technical scheme, the preparation method hasthe benefits as follows: the mixed prepolymer is prepared from allyl glycidyl ether, an acrylate monomer and hydroxyl-terminated polydimethyl siloxane by polymerization, so that the prepared adhesivehas the advantages of epoxy resin and acrylic resin, has low viscosity, better elasticity after curing molding, less volume shrinkage and performance characteristics of excellent high-temperature andhigh-humidity resistance.

Description

technical field [0001] The invention relates to the field of light-curing adhesives, in particular to a preparation method of UV-curable adhesives for glass films. Background technique [0002] Ultraviolet light (uv for short) curing technology is an advanced technology that appeared in the 1960s. It uses uv to trigger rapid polymerization and crosslinking of chemically active liquid materials, and instantly solidifies to form a film. It is an industrial technology with "5E" characteristics : High efficiency, wide adaptability, economy, energy saving and environmental friendliness. The Radiation Curing Professional Committee counted the economic information of 109 major uv curing-related manufacturers in 2004: the growth rate of uv curing adhesive output and output value was 218.4% and 243.8%, which was much higher than that of uv coatings and inks and other types of adhesives. The growth rate of the mixture will continue to be very rapid in the next few years. UV light-cu...
