A kind of ultraviolet light mixed curing adhesive for display and preparation method thereof

Abstract

The invention provides an ultraviolet mixing solidifying adhesive for a display and a preparation method thereof.The ultraviolet mixing solidifying adhesive for the display is prepared from, by weight, 40-90 parts of polyurethane graft modification sulfur-containing epoxy monoacrylate with the grafting ratio being 50% or above, 10-45 parts of an activated thinner, 1-5 parts of a photoinitiator and 1-10 parts of a thermal curing agent.By adopting the technical scheme, the adhesive is cured with the mixture of ultraviolet light and heat, has the high bonding strength for glass base materials and the like, meanwhile has the high refractivity, can meet the requirement for adhesion fixation of optical components in the display, and can also solve the problem that an existing adhesive is low in refractive index and the like, wherein the refractive index of the adhesive is 1.50 or above.

Description

technical field

[0001] The invention belongs to the technical field of adhesives, in particular to an ultraviolet light mixing and curing adhesive for displays and a preparation method thereof. Background technique

[0002] Optical materials mainly include inorganic materials and organic (polymer) materials. The refractive index of an optical material is one of the most important indicators of its optical performance and has a decisive impact on the application of the material. Inorganic optical materials (commonly known as "optical glass") have a long history and many varieties. n D=1.437-1.935, including colorless optical glass,) colored optical glass, radiation-resistant optical glass, radiation-resistant glass and optical quartz glass, etc., are widely used in the industry to manufacture lenses, prisms, mirrors, windows, etc. of optical instruments . The refractive index of inorganic optical materials can be selected in a wide range, with high refractive index, good l...
