Problems solved by technology

[0003] In the prior art, the fog surface pressure-sensitive adhesive used for LED lamp tubes has the following technical problems: (1) The problem and deficiency of the uniformity of the fog surface of the lamp tube; (2) The LED lamp tube has cracks. Possibly, so 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 mist side pressure-sensitive adhesive. The pressure-sensitive adhesive consists of the following components in parts by weight: 100 parts of an acrylic ester adhesive, 30-50 parts of a diluting agent, 0.5-2 parts of an isocyanate crosslinking agent, 0.5-2 parts of an epoxy crosslinking agent, 5-20 parts of rosin resin, 2-15 parts of an azo compound, 2-15 parts of an N-nitroso compound, 0.5-2 parts of a coupling agent and 0.3-1.5 parts of an acrylic ester polymer. The mist side pressure-sensitive adhesive realizes uniformity and a mist side of light, improves the transmittance of the light and the adhesive force between a polyester film layer and a lamp shade at the same time, has high-temperature resistance, and ensures the reliability of product performance.

Description

technical field [0001] The invention relates to a matte pressure-sensitive adhesive, which belongs to the technical field of 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 fog surface pressure-sensitive adhesive used for LED lamp tubes has the following technical problems: (1) The problem and deficiency of the uniformity of the fog surface of the lamp tube; (2) The LED lamp tube has cracks. Possibly, 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 lon...
