Embodiment 1

[0008] UV-curable acrylate adhesive, composed of the following components in parts by mass: 45 parts of methyl methacrylate, 55 parts of butyl acrylate, 8 parts of vinyl acetate, 4 parts of acrylic acid, 10 parts of dioctyl phthalate 0.5 parts of benzoyl peroxide, 65 parts of toluene, 8 parts of tetrahydrofuran methanol, 7 parts of quartz powder, and 1 part of ammonium persulfate.

[0009] The preparation process is as follows: the temperature of the monomer is raised under the protection of nitrogen, and after the polymerization starts at 80°C, other components are added in sequence, and the temperature is naturally lowered after 2 to 3 hours of reaction.

[0010] The UV-curable acrylate adhesive provided by the present invention, in the double-layer glass test, at 40°C, the steel ball 227g does not penetrate when dropped from 12m, and the weight of the peeled fragments on the back is less than 20g, and it does not age when boiled at 100°C for 3 hours. The shear strength is m...

Abstract

A UV curing acrylic ester adhesive is composed of, by mass, 40-50 parts of methyl methacrylate (MMA), 50-60 parts of butyl acrylate, 5-10 parts of vinyl acetate, 3-5 parts of acrylic acid, 5-20 parts of dioctyl-phthalate (DOP), 0.2-1 part of benzoyl peroxide, 60-70 parts of toluene, 5-10 parts of tetrahydrofurfuryl alcohol, 5-10 parts of quartz powder and 0.5-2 parts of ammonium persulfate. According to the UV curing acrylic ester adhesive, in a double glass detection under 40 DEG C, the glass cannot be penetrated by a 227g steel ball which falls from a height of 12m, spalling fragments at the back are lighter than 20g, the glass cannot be aged after three hours of water boiling at 100 DEG C, and the shear strength maintains at 6-7MPa.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an ultraviolet-curable acrylate adhesive. Background technique [0002] UV-curable adhesive is a kind of adhesive that has developed rapidly in recent years. It uses ultraviolet light to trigger rapid polymerization and crosslinking of chemically active liquid materials, and solidifies into a film within a few seconds. It is a high-performance, high-efficiency adhesive. of adhesives. By synthesizing prepolymers, modifying them with reactive diluents, and adding various photoinitiators, ZUV series UV-curable adhesives were prepared. This series of UV curing adhesives has the advantages of fast curing speed, high bonding strength and good shock resistance. It has been widely used in the bonding of metal, glass, crystal, stone and other materials, and has good social and economic benefits. However, the existing adhesives also have many deficiencies, such as poor impact resistan...
