Problems solved by technology
[0003] At the same time, we must also realize that there are still some difficult technical problems in the application research of UV curing adhesives, such as short irradiation time, low conversion rate of monomers, and strong odor of residual monomers in adhesive products. ;Stronger UV radiation may damage the substrate, so the scope of application is narrow; at the same time, UV-curable adhesives still have unsatisfactory properties such as flexibility and bond strength

Abstract
The invention provides a UV curable adhesive and its use method. The adhesive includes the following components in parts by mass: 0.5-6 parts of photosensitizer, 75-85 parts of acrylate copolymer, polyurethane acrylate prepolymer 5-15 parts, the balance is coupling agent and / or leveling agent, the above components are 100 parts in total; the photosensitizer consists of bis(2,6-dimethyloxybenzoyl)-2,4,4 —Mixed trimethylpentylphosphine oxide and tertiary amine acrylate. It is suitable for use with low radiation intensity, has the advantages of wide application range, high bonding strength, and good flexibility, and is especially suitable for bonding soft-based flexible materials.
Description
Technical field [0001] The present invention relates to the field of adhesives, and is specifically a UV cured adhesive and a method of use. Background technique [0002] The adhesive has a wide range of applications in various fields, and the species are also particularly useful. UV cured adhesive refers to an adhesive that can be quickly cured under ultraviolet light, specifically, the photosensitizer in the adhesive system is irradiated / radiation in an appropriate wavelength and intensity of ultraviolet light / radiation, which forms active debris, these The active debris initiates an unsaturated monomer for polymerization, crosslinking, and the like to achieve rapid curing. UV cured adhesives have the advantages of fast curing speed, less pollution, energy saving, environmentally friendly, so UV cured adhesive is the focus of adhesive research and development in recent years. For example, 3M, Han Gaulitai, three-bonded adhesive adhesive production enterprises have correspon...
