Embodiment 1

[0020] A preparation method of high-performance glass thinning glue, calculated in parts by mass, first weighs 15 parts of isobornyl acrylate, 10 parts of tetrahydrofurfuryl acrylate, 3 parts of acyl phosphine oxide and 1 part of benzoin, and mixes them, Heat to 40-50°C and stir at 1200-2000r / min for 40-45min. Then add 35 parts of urethane acrylate, 30 parts of pure acrylic resin, 5 parts of 2-functional epoxy acrylate and 0.8 parts of coupling agent in sequence, after stirring for 20-30 minutes, add 0.2 parts of wetting agent, and stir for 10-15 minutes. Filter with a 300-mesh filter, and pack the filtrate to obtain the glass-thinning glue. The performance of gained glass thinning glue is as follows:

Abstract

The invention discloses high-performance glass thinning glue and a preparation method thereof. The high-performance glass thinning glue is prepared from the following raw materials in parts by mass: 40-70 parts of low polymer, 20-40 parts of acrylate active monomer, 1-5 parts of a photoinitiator and 1-5 parts of auxiliary. The prepared high-performance glass thinning glue is not only good in adhesion performance on glass, acid and alkali resistant and environmentally friendly (no solvent is added, and heavy metals, methylbenzene, formaldehyde and methyl alcohol meet the European Union ROSH andREACH standards), but also good in tenacity and easy to remove.

Description

technical field [0001] The invention belongs to the technical field of chemical products, and relates to a high-performance glass-thinning adhesive cured by ultraviolet light without solvent, in particular, to a high-performance glass-thinning adhesive used in the thinning process of FPD photoelectric glass and its preparation method. Background technique [0002] The FPD photoelectric glass finishing industry is an important part of the production of the flat panel display manufacturing industry. With the development of the flat panel display industry and the improvement of people's living standards, consumers' requirements for display technology and display products are also constantly increasing. Flat panel display products continue to develop in the direction of "thin, light, energy-saving, and high-precision". Devices and related components supporting industries such as thinning, coating, yellow light, cutting and other production equipment have higher and higher preci...
