Abstract

The invention relates to the technical field of photo-curing materials and particularly relates to an environment-friendly UV curing adhesive and a preparation method thereof. The environment-friendlyUV curing adhesive comprises the following components: 60-70 parts of a prepolymer, 10-20 parts of a reactive diluent A, 10-15 parts of a photoinitiator and 0.5-10 parts of a reactive diluent B, wherein the prepolymer is modified epoxy acrylate; the reactive diluent A is hydroxyethyl methylacrylate; the photoinitiator is 2,2-dimethyl-alpha-hydroxyphenylacetone; the reactive diluent B is trimethylolpropane triacrylate. According to the UV curing adhesive, a proper ratio of raw materials is adopted; the functions of all the components are fully exerted; the UV curing adhesive is rapid in curingspeed, excellent in flexibility and high in adhesion strength, and is non-toxic and harmless.

Description

technical field [0001] The invention relates to the technical field of photocurable materials, in particular to an environment-friendly UV curing adhesive and a preparation method thereof. Background technique [0002] With the development of science and technology, mobile phones, notebook computers, tablet computers, ultra-thin TVs, navigators and other products have developed rapidly, and the demand for electro-acoustic devices is increasing. In the traditional process, the production of electro-acoustic devices mainly relies on solvent glue to bond components such as brackets, diaphragms and voice coils. However, solvent glue is highly toxic and harmful to the human body, so it is difficult to meet new requirements such as halogen-free, and its performance is not good. Stablize. [0003] The curing principle of UV-curable adhesives is: the photoinitiator (or photosensitizer) in the UV-curable material, under the irradiation of ultraviolet light, absorbs ultraviolet light...
