Abstract

The invention provides a transparent block network epoxy resin-silicone rubber modified material with excellent comprehensive performance, which is prepared from the following raw materials in parts by weight: 100.00 parts of silicone rubber, 1.00 to 1.00 parts of bifunctional epoxy resin 20.00 parts, 3.00-50.00 parts of hydrogen-containing silicone oil, 0-1.00 parts of rubber additive, wherein the bifunctional epoxy resin contains both epoxy groups and vinyl groups. The epoxy-silicone rubber modified material of the present invention has obvious improvement in tensile strength, elongation at break, and bonding performance compared with pure silicone rubber, and maintains the transparent performance of silicone rubber. It can not only be used in aerospace, High-temperature-resistant coatings, adhesives, potting compounds, rubber, and flexible ablation-resistant substrate materials in the fields of electronic information, mechanical equipment, etc., can also be used in solar panel transparent coatings, LED packaging materials, etc. Prospects are excellent.

Description

technical field

[0001] The invention belongs to the field of polymer modified materials, in particular to a transparent bifunctional epoxy resin-silicone rubber block network material. Background technique

[0002] Silicone rubber is a polymer elastic material whose molecular chain has both inorganic and organic properties. Due to the particularity of its structure and composition, silicone rubber materials have many excellent properties that other materials cannot have at the same time, such as excellent high and low temperature resistance, good transparency, excellent oil resistance, solvent resistance, UV resistance, and radiation resistance. , excellent electrical insulation and chemical stability and physiological inertness and other advantages, has been widely used in aviation, aerospace, electrical and electronic, mechanical equipment, biomedicine and organic coating industries and other fields. In recent years, silicone rubber has also been widely used in optical fi...
