Abstract

The invention discloses an air conditioner outdoor unit shell material and a preparation method thereof. The air conditioner outdoor unit shell material is prepared from, by weight, 0-30 parts of PET, 40-60 parts of PBT, 30-50 parts of glass fibers, 0.2-1.6 parts of processing agent, 0-0.2 part of ester exchange inhibitor, 6-16 parts of fire retardant, 0-2 parts of light stabilizer and 0-5 parts of antibacterial agent through mixing and squeezing granulation. PET which has low price relative to PBT and the glass fibers are comprehensively used for preparing the material, cost is reduced, and the strength of the material is improved; in addition, by adding the light stabilizer, the flame retardant and the antibacterial agent at different ratios, the material has good weather fastness, a good flame-retardant effect and a good mildew-proof function, and can be used for other outdoor weather-proof bearing shells.

Description

technical field [0001] The invention relates to the technical field of polymer alloys, in particular to a PBT / PET alloy material that can be used for an air conditioner outdoor casing and a preparation method thereof. Background technique [0002] At present, most of the outdoor casings of air conditioners on the market are made of metal materials, which have defects such as poor corrosion resistance, easy rust, and easy resonance with the air conditioner compressor to generate noise. In order to solve the defects of metal shells, plastics are also used to make air conditioner shells, but practice has proved that plastic products are often corroded by molds. In addition to considering factors such as weather resistance, strength, and flame retardancy, the research on using plastics to replace metal materials for outdoor casings of air conditioners also takes into account the anti-mildew effect, which is very difficult.
