Abstract

The invention belongs to the technical field of macromolecule materials and provides an ultraviolet-resistant organic silicon adhesive and a preparation method thereof. The ultraviolet-resistant organic silicon adhesive comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 20-50 parts of an epoxy group containing alkene type unsaturated compound, 10-18 parts of vinyl terminated polysiloxane of 400-2000cps, 0.5-1 part of polyvinyl polysiloxane and 0.009-0.1 part of a platinum catalyst; the component B comprises the following components in parts by weight: 25-40 parts of f vinyl terminated polysiloxane of 400-2000cps, 10-16 parts of terminated hydrogen-containing polysiloxane, 5-10 parts of o-hydroxydibenzophenone and 0.5-5parts of a polyallyl compound; and the weight percentage of platinum in the platinum catalyst is 0.1-0.15%. The component A is prepared in an opening system, the component B is prepared in a sealed system, and the two components are mixed to prepare the adhesive. By adopting the preparation method of the ultraviolet-resistant organic silicon adhesive, production conditions can be simplified, the production time can be shortened, and the prepared ultraviolet-resistant organic silicon adhesive has a very high refractive index, light transmittance and ultraviolet aging resistance.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to an ultraviolet-resistant organic silica gel adhesive and a preparation method thereof. Background technique

[0002] So far, most of the traditional production processes of adhesives are completed in several stages such as high-speed dispersion, high-pressure extrusion, vacuum defoaming and extrusion filling in a vacuum mixer. In these production processes, there are generally some technical defects, such as: harsh production conditions, complicated production process, long production time, low production efficiency and so on.

[0003] Adhesives currently on the market generally have bubbles and degumming under long-term exposure to ultraviolet light, resulting in failure to use normally. With the wide application of silicone adhesives in various industrial and technical fields, its preparation process has also received attention and research. How to devel...
