Problems solved by technology

[0003] The LED light tube is a row of LED light-emitting units installed inside the light-transmitting light tube. The technical problems of the existing technology are as follows: (1) There are problems and deficiencies such as poor light transmittance, large attenuation of transmitted light, and poor uniformity of the fog surface. ; (2) The LED tube may be broken, which poses a safety hazard; (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 microporous acrylic adhesive tape. A pressure-sensitive adhesive layer of the microporous acrylic adhesive tape is adhered to the outer surface of an LED light; the surface of the pressure-sensitive adhesive lay which is opposite to a lamp shade is adhered to a polyester film layer, and the surface of the polyester film layer is coated with a foggy surface coating layer. The surface roughness of the fogging surface coating layer is 0.1-0.8 microns; the pressure-sensitive adhesive layer comprises 100 parts of acrylic ester adhesive, 30-50 parts of diluent, 0.5-2 parts of isocyanate cross-linking agent, 0.5-2 parts of epoxy cross-linking agent, 5-20 parts of rosin resin, 2-15 parts of azo compound, N2-15 parts of N-nitroso-compounds, 0.5-2 parts of coupling agent, and 0.3-1.5 parts of acrylic ester polymer. The microporous acrylic adhesive tape overcomes the deflect of viscosity and adhesive force reduction caused by air holes while realizing uniform light and fogging surface, so that the adhesive strength and adhesive force between polyester film layer and the lamp shade are improved, and then the product reliability is improved.

Description

technical field [0001] The invention relates to a microporous acrylic adhesive tape, which belongs to the technical field of acrylic adhesive tape. Background technique [0002] LED can directly convert electricity into light. At the same time, LED has the characteristics of long life, high luminous efficiency, no radiation, impact resistance and low power consumption. In order 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] The LED light tube is a row of LED light-emitting units installed inside the light-transmitting light tube. The technical problems of the existing technology are as follows: (1) There are problems and deficiencies such as poor light transmittance, large attenuation of transmitted light, and poor uniformity of the fog surface. ; (2) The LED lamp tube may be broken, which po...
