Problems solved by technology

At present, the thermal deformation temperature of cross-flow fan materials produced by domestic manufacturers is usually 102°C. If the fan is used for a long time at 60°C, it will easily cause the fan to deform, thereby affecting the cooling and heating efficiency of the air conditioner and increasing the noise.

Abstract

The invention provides a high temperature resistant material for a cross flow fan of an air-conditioning internal machine, which is characterized by consisting of the following components in part by weight: 30 to 55 parts of universal acrylonitrile styrene copolymer, 10 to 30 parts of heat resistant acrylonitrile styrene copolymer, 3 to 5 parts of compatilizer, namely styrene-maleic anhydride copolymer, 4 to 8 parts of heat resistant agent, namely sodium carboxymethyl starch, 29 to 31 parts of glass fiber, 0.5 to 1 part of lubricant TAF, 0.1 to 0.3 part of antioxidant 1076, 0.2 to 0.4 part of antioxidant 168 and 0.2 to 0.4 part of silane coupling agent KH550. Compared with the prior art, the material has the advantage of guaranteeing that at a high temperature, the fan alleviates the deformation phenomenon by rotating at a high speed.

Description

technical field [0001] The invention provides a high temperature-resistant cross-flow fan material for an air conditioner internal unit, which belongs to the technical field of air conditioner materials. Background technique [0002] At present, the fans of household air conditioners used in China are all made of AS+ glass fiber materials. But in terms of its mechanical properties and thermal properties, each has its own merits. At the same time, in terms of mechanical properties, all manufacturers can basically meet the requirements of use, but little progress has been made in terms of thermal properties. With the popularization of home appliances and the frequent occurrence of high temperature weather, the requirements for the thermal performance of air conditioner fans are also increasing. At present, the thermal deformation temperature of cross-flow fan materials produced by domestic manufacturers is usually 102°C. If it is used for a long time at 60°C, it will easily c...
