Abstract

The invention provides a dual-curing pressure-sensitive adhesive tape. The dual-curing pressure-sensitive adhesive tape is prepared from the following raw materials in parts by weight: 90-110 parts of acrylate monomer, 15-26 parts of acrylic monomer and 6-10 parts of rubber elastomer, 6 to 10 parts by weight of carbodiimide, and 12 to 15 parts by weight of trimethylolpropane trimethacrylate; the adhesive is prepared from the following components in parts by weight: 16 to 20 parts of tackifying resin, 6 to 12 parts of dibenzoyl oxide, 4 to 10 parts of benzoin diethyl ether and 20 to 30 parts of modified polyacrylamide polymer. The dual-curing pressure-sensitive adhesive tape disclosed by the invention can be rapidly cured no matter at the temperature of 45 DEG C or above or under the condition of ultraviolet irradiation with the intensity of more than 1500LEX, and the working efficiency and the yield are improved in the actual processing and production of electronic products.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a dual-curing pressure-sensitive adhesive tape. Background technique [0002] With the rapid development of the electronic information industry, electronic devices such as mobile phones, tablet computers, Kindle, and smart bracelets have developed rapidly. At present, most of their screens use flexible electronic substrate displays. Compared with traditional hard glass substrate displays, Flexible electronic substrate displays are ultra-thin, bendable, and shock-resistant. From the perspective of the cost structure of flexible panels and related application products, the construction of flexible panel modules (flexible touch panels, color electronic paper, and color filters) accounts for about 28-32% of the cost. If the panel is damaged so that it cannot be used, the overall production cost will be greatly increased. Therefore, it is an important issue to improve the alignment...
