Abstract

The invention provides a display device, a modified ABS material and a preparation method of the modified ABS material . The modified ABS material comprises the following components in parts by weight: 35-45 parts of a glass fiber reinforced butadiene-styrene material and 45-65 parts of a grafted acrylonitrile-styrene copolymer, wherein the glass fiber reinforced butadiene-styrene material comprises 10 to 20 parts of glass fibers and 80 to 90 parts of butadiene-styrene; and the grafted acrylonitrile-styrene copolymer comprises 10 to 30 parts of polyethylene glycol terephthalate and 70 to 90 parts of an acrylonitrile-styrene copolymer. According to the modified ABS material, an ordered microphase is generated through polybutylene terephthalate, and the swelling effect of grease on a plastic body is inhibited, so the oil resistance of the acrylonitrile-styrene copolymer is realized, and the oil resistance of the modified ABS material is further realized.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a display device, a modified ABS material and a preparation method thereof. Background technique [0002] The display device is applied in the life of the user, and can display different interfaces for the user to watch. The display device is mainly a TV, a monitor, and the like. [0003] At present, the material of the front case of the display device mainly includes two types of plastic and metal. Among them, the metal front shell is mainly used in high-end TVs because of its high appearance and high quality. However, whether it is a four-frame front case or a lower front case platform structure, the surface temperature of the metal material is basically the same as the temperature inside the display device due to its high thermal conductivity, which makes the surface temperature of the front case high and hot. The problem is The industry has been unable to solve the ...
