Problems solved by technology

However, ABS will produce photocorrosion effect under the irradiation of the light source. After the light source is irradiated, the structure of the trace colored substance in the ABS material changes, making the color of the ABS resin turn white and yellow. When the color of the air conditioner shell is white or light , it is easy to cause users to not see the LED display numbers on the panel, which seriously affects the use of consumers and the appearance of the air conditioner

Abstract

The invention provides a modified air conditioner blower shell and a preparation method for the same. The modified air conditioner blower shell is prepared from the following raw materials: crushed ABS (acrylonitrile butadiene styrene) resin, a grafted terpolymer prepared from butadiene, acrylonitrile and acrylate, tetrabromobisphenol A, titanium dioxide, microcrystalline wax, an antioxidant and a B-215 long-acting heat stabilizer. The air conditioner blower shell disclosed by the invention is high in photo-corrosion resistance, and has a relatively broad market prospect and relatively good economic benefits, the phenomenon that a conventional air conditioner housing easily gets yellow and white under long-term irradiation of an LED (long-emitting diode) light source is well relieved, and a good user experience is provided.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a modified air conditioner blower casing and a preparation method thereof. Background technique [0002] With the continuous improvement of people's material living standards, the requirements for air-conditioning products are no longer limited to the basic heating and cooling functions, but have higher requirements for their shape, structure, composition materials, and surface weather resistance. Most of the existing air-conditioning blower shells are made of ABS resin plastics. ABS resin not only has excellent mechanical properties with balanced toughness, hardness and rigidity, but also has good dimensional stability, surface gloss and low temperature resistance. However, ABS will produce photocorrosion effect under the irradiation of the light source. After the light source is irradiated, the structure of the trace colored substance in the ABS material changes, making t...
