Embodiment Construction

[0022] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. The present invention will be described in detail below in conjunction with embodiments.

[0023] As described in the background art, the existing problem exists that the bonding strength and weather resistance of the adhesive cannot be combined. In order to solve this problem, the present invention provides a UV-curable adhesive. In parts by weight, the adhesive includes 5-20 parts of polyester acrylate oligomer and 15-35 parts of urethane acrylate. , 5-20 parts of epoxy acrylate, 50-120 parts of reactive diluent and 1-3 parts of photoinitiator.

[0024] The above-mentioned adhesive provided by the present invention simultaneously contains three unsaturated oligomers of polyester acrylate oligomer, urethane acrylate and epoxy acrylate. Polyester acrylate oligomer has low viscosity and good compatibility with other componen...

Abstract

The invention provides an ultraviolet curing adhesive. The ultraviolet curing adhesive comprises the following components in parts by weight: 5-20 parts of polyester acrylate oligomer, 15-35 parts of urethane acrylate, 5-20 parts of epoxy acrylate, 50-120 parts of an active diluent and 1-3 parts of a photoinitiator. The adhesive comprises three unsaturated oligomers, namely, polyester acrylate oligomer, urethane acrylate and epoxy acrylate at the same time, so that the bonding strength and weather resistance of the adhesive can be effectively improved, and the adhesive is enabled to have a better comprehensive property; the dosage of the components is limited within the range, so that the ultraviolet curing adhesive with high bonding strength, good weather resistance and a good coating processing property is obtained.

Description

Technical field [0001] The invention relates to the field of light curing adhesives, and in particular to an ultraviolet light curing adhesive. Background technique [0002] Ultraviolet curing adhesive is an adhesive with the characteristics of rapid curing, environmental protection, strong adhesion, no thermal effect during curing, and wide application range. The principle is to use a photoinitiator to initiate the polymerization, grafting, crosslinking and other chemical reactions of unsaturated organic monomers to achieve rapid curing under ultraviolet light irradiation. Because of its short curing time, high energy utilization rate, low curing temperature, and no environmental pollution, it has attracted widespread attention as soon as it appeared. [0003] The patent application with publication number CN102898980 provides a UV-curable acrylate adhesive, which is made of methyl methacrylate, butyl acrylate, vinyl acetate, toluene and the like. The adhesive has the advantages...
