Abstract

The invention discloses UV (Ultraviolet) / moisture double cured silicon rubber, which consists of the following components in parts by weight: 25-80 parts of methacrylic acid modified organic silicon, 10-30 parts of an active diluted monomer, 3-5 parts of a filler, 2-5 parts of a photo-initiator, 0.2-0.5 part of a catalyst, 5-10 parts of a silane coupling agent and 0-1 parts of other additives. The UV / moisture double cured silicon rubber has the advantages of quick curing, high efficiency and reduction in production cost. An adhesive fully meets the process requirements of protection production of a laminated adhesive for protecting a PCB (Printed Circuit Board) and a COG (Chip on Glass) chip.

Description

technical field [0001] The invention relates to the field of macromolecular materials, in particular to UV / moisture dual-curing silicone rubber and a preparation method thereof. Background technique [0002] The special structure of silicone endows it with many excellent properties, such as high and low temperature resistance, weather resistance, aging resistance, corrosion resistance, low surface tension and physiological inertness, etc. , daily life and other aspects have been widely used. The photo-curing technology has the advantages of fast curing, low energy consumption, high efficiency, and no pollution. It is in full compliance with the "3E" principle: Energy (energy saving), Ecology (ecological environmental protection), and Economy (economy). It is an environmentally friendly green technology. . Light-curing silicone materials are favored due to the excellent performance of silicone materials and the high-efficiency and energy-saving features of light-curing tech...
