Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an anti-fog treatment process for the surface of the injection molded sealing screen shell, which meets the requirements of anti-fog from the perspectives of non-contact cleaning, high-clean operating environment, mutual dust-free interference, and relatively closed whole process. According to the requirements of coating characteristics, it can effectively solve the problems of air bubbles, dust spots and unsatisfactory anti-fog performance after spraying the injection-molded sealing screen shell, and also reduce the coating cost

Embodiment Construction

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] refer to figure 1 , figure 2 , now explain the surface process treatment of a TV injection molded screen cover, as shown in the figure, first use the spray masking tool 1 to cover the area that does not need to be sprayed on the cover 4, and the unshielded area is the spray area 2, and then Spraying is carried out, and finally a sprayed layer 3 is formed on the sprayed area 2 .

[0032] In this embodiment, an injection molding process is used to make the screen cover 4 of the TV set, and the material is polymethyl methacrylate (PMMA), also known as acryli...

Abstract

The invention is suitable for the injection sealed screen shell processing field and provides an injection sealed screen shell surface antifogging processing technology. The processing technology comprises the following steps: 1) the surface of a sealed screen shell to be sprayed is cleaned; 2) an antifogging and antistatic paint is sprayed on the sealed screen shell; 3) the sprayed sealed screen shell is roasted; and 4) the roasted sealed screen shell is placed in an environment with constant temperature and humidity. Compared with the prior art, the processing technology can effectively solve the problems that after sprayed, the injection sealed screen shell has mutiple bubbles and dirt pits and unsatisfactory antifogging performance; and the coating cost can be reduced. Meanwhile, the invention also provides an injection sealed screen shell with antifogging function which is prepared by the technology. The invention also provides a video electronic device which uses the injection sealed screen shell with antifogging function; and the sealed screen shell of the device has small possibility of generating water mist and static electricity and the video electronic device has good visual effect.

Description

technical field [0001] The invention belongs to the field of screen-sealing shell processing, and more specifically relates to an anti-fog treatment process for the surface of an injection-molded screen-sealing shell, a product, and video electronic equipment. Background technique [0002] At present, most of the TVs using the screen sealing technology are made of transparent plexiglass injection molding. As the temperature continues to rise and water vapor precipitates, tiny water mist will condense on the surface of the TV panel, directly affecting the viewing effect of customers. Moreover, the LCD screen is sealed inside the whole machine, and frequent switching will bring a large amount of electrostatic dust adsorption, which not only affects the life of the TV screen itself, but also poses a safety hazard to customers. [0003] The main research direction at home and abroad is surface coating or film sticking. Through coating or film sticking technology, on the basis o...
