Problems solved by technology

[0003] As the fourth generation of adhesives, light-curable adhesives still have many shortcomings. For example, due to the difference in surface energy of materials, the scope of application of existing light-curable adhesives is limited. Especially in order to obtain suitable performance, various organic materials are blended and modified to become Commonly used methods, thus putting forward higher requirements for adhesives, how to deal with the variability of substrates has become a problem that must be solved in the field of light-curing adhesives
At the same time, higher lighting requirements have also become an obstacle to the application

Embodiment 1

[0027] Example 1: At normal temperature and pressure, N, N dimethylacrylamide, hexanediol diacrylate, isobornyl acrylate, ethoxyethoxyethyl Add acrylate to the container and mix evenly; then slowly add vinyl chloride and vinyl acetate copolymer resin into the container while stirring to prevent agglomeration until the vinyl chloride and vinyl acetate copolymer resin is completely dissolved and becomes a colorless transparent liquid; Add polyester polyurethane diacrylate and 2-hydroxy-2-methyl-1-phenyl-1-propyl ketone, 1-hydroxycyclohexyl benzophenone, 2,4,6-trimethyl Benzoyl diphenyl phosphine oxide and vinyl tritert-butyl peroxysilane were stirred for 0.5 hours, left to stand for 1 day to mature, and the sampling test was qualified, and the adhesive was obtained by filtering. During the production process, it should be protected from moisture and light, and the container and agitator should not react with the processing materials, especially vinyl tritertbutylperoxysilane.

Embodiment 2

[0028] Embodiment 2: Repeat the preparation method of Example 1 according to the content of each component specified in Table 1, but the stirring time is 40 minutes, after standing for 30 hours of aging, the sampling test is qualified, and the adhesive is made by filtering.

Embodiment 3

[0029] Embodiment 3: Repeat the preparation method of Example 1 according to the content of each component specified in Table 1, but the stirring time is 45 minutes, after standing for 35 hours of aging, the sampling test is qualified, and the adhesive is made by filtering.

Abstract

The invention discloses an ultraviolet light curing adhesive and a preparation method thereof. Polyester polyurethane diacrylate, N, N-DMA, iso-bornyl acryl, HDDA, ethoxyethoxy ethyl acrylate, vinyl chloride and vinyl acetate copolymer resin, 2-hydroxyl-2-methyl-1-phenyl-1-propyl ketone, 1-hydroxy cyclohexyl phenyl ketone, 2,4,6-trimethyl benzoyl diphenyl phosphine oxide and three t-butyl peroxy vinyl silane are mixed at the ratio. The adhesive can be used for various kinds of organic substrate, glass, metal and the like, can cure under medium viscosity, ultraviolet light or visible light, can fulfil optical bonding requirements and makes up for the deficiency of the existing optical bonding adhesive.

Description

technical field [0001] The invention relates to the field of light-curing adhesives, in particular to an adhesive that can be irradiated with ultraviolet light of 253.7 nanometers and 365 nanometers and visible light of 420 nanometers and a preparation method thereof. Background technique [0002] With its unique technical advantages such as fast curing speed, room temperature curing, energy saving, and environmental protection requirements (low or zero emission of volatile organic compounds VOC), UV-curable adhesives have shown strong vitality, and they are the technological transformation of traditional industries. And the establishment and development of high-tech industries, especially the electronic information industry, provides advanced technical means, which are widely used in chemical industry, machinery, electronics, light industry, transportation, communication, national defense, anti-terrorism security and other fields. It can also avoid possible damage to variou...
