Problems solved by technology

[0003] Traditional TV racks mostly use steel materials such as steel plates or cast iron. The disadvantages are high cost, heavy weight, and troublesome processing.
At the same time, the frame material should also have good insulation properties. If metal materials are used, insulating paint should be coated on the outer layer, which further increases the cost.

Abstract

The invention relates to the technical field of racks of televisions and particularly relates to a high-strength and stain-resistant plastic rack for a liquid-crystal television. An alloy material is prepared from the following raw materials: HIPS, TPEE, silver-supported cobalt phosphate, fluorosilicone rubber, glass fibers, modified active magnesium hydroxide, aerosil, antimony trioxide, aluminum hydroxide, isodecyl-diphenyl phosphite, EVA, tri(2,4-di-tert-butylphenyl)phosphite, polydiphenylsulfonyl phenylphosphonate, 2,4-dihydroxy benzophenone, modified calcium carbonate, a solubilizer, a curing agent and a coupling agent. Due to the glass fibers, the material is endowed with better mechanical properties and wear resistance; due to the silver-supported cobalt phosphate and the fluorosilicone rubber, the antibacterial and medium-resisting properties of the material can be remarkably improved, particularly the acid / base resistance is excellent; meanwhile, the weather resistance, ozone resistance and radiation resistance of the material are improved, and the requirements of the rack for the liquid-crystal television on high strength, stain resistance and high cost performance are met; the manufacturing process of the product is simple, so that the industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of television frames, in particular to a high-strength and anti-pollution plastic frame for liquid crystal televisions. Background technique [0002] With the rapid development of the national economy, the substantial improvement of people's living standards, and the rapid development of TV technology, especially the application of OLED and other technologies in TV-related industries, TV sets are developing towards large-screen, ultra-thin and other trends. . At present, there are mainly two installation methods of LCD TVs: base-mounted and wall-mounted. The base type needs to purchase the corresponding TV cabinet to support. The TV cabinet is generally relatively large in volume and weight, which not only occupies a large space, but also has the disadvantage of inconvenient movement. Therefore, more and more families choose to install the TV on the wall. The wall-mounted type generally needs the wall to b...
