Problems solved by technology

[0003] In the prior art, the pressure-sensitive adhesive used for LED lamp tubes has the following technical problems: (1) the problem and deficiency of the poor uniformity of the fog surface of the lamp tube; (2) the possibility of cracking of the LED lamp tube, thus There are potential safety hazards; (3) The temperature resistance and reliability are poor. If the temperature rises casually and the temperature difference changes, the viscosity and performance of the product will decay after a long time

Abstract

The invention discloses a high-temperature resistance matte acrylic acid adhesive. The matte acrylic acid adhesive is composed of following components in parts by weight: 100 parts of acrylic acid adhesive, 30 to 50 parts of diluent, 0.5 to 2 parts of isocyanates cross-linking agent, 0.5 to 2 parts of expoxy cross-linking agent, 5 to 20 parts of rosin resin, 2 to 15 parts of azo compound, 2 to 15 parts of N-nitroso compound, 0.5 to 2 parts of coupling agent and 0.3 to 1.5 parts of acrylic acid ester polymer. The high-temperature resistance matte acrylic acid adhesive realizes the uniformity of LED light and matte, improves the adhesive force between the polyester thin film layer and the lampshade, and also has a high-temperature resistance performance, thus the reliability of the product performance is guaranteed.

Description

technical field [0001] The invention relates to a high-temperature resistant matte acrylic adhesive, which belongs to the technical field of acrylic adhesives. Background technique [0002] With the maturation and improvement of photoelectric industry technology, in order to save electricity to meet the requirements of energy saving and environmental protection, and to meet the needs of different users, more and more manufacturers have developed LED lamps to replace fluorescent lamps in traditional technology. [0003] In the prior art, the pressure-sensitive adhesive used for LED lamp tubes has the following technical problems: (1) the problem and deficiency of the poor uniformity of the fog surface of the lamp tube; (2) the possibility of cracking of the LED lamp tube, thus There are safety hazards; (3) The temperature resistance and reliability are poor. If the temperature rises casually and the temperature difference changes, the viscosity and performance of the product ...
