Technical Field

The invention belongs to the field of high polymer material engineering, and particularly relates to an ABS alloy material capable of releasing negative oxygen ions, and a preparation method and application thereof.

Background

The ABS resin is a terpolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S). ABS plastics have the common properties of three components, A makes it resistant to chemical corrosion and heat and has a certain surface hardness, B makes it have high elasticity and toughness, and S makes it have the processing and forming characteristics of thermoplastic plastics and improves the electrical properties. Therefore, the ABS plastic is a tough, hard and rigid material which has easily obtained raw materials, good comprehensive performance, low price and wide application.

The glass fiber reinforced plastic has the advantages of high specific strength, corrosion resistance, heat insulation, small molding shrinkage and the like. In addition, the glass fiber reinforcement can greatly improve the tensile property of the plastic. The glass fiber added into the ABS resin can enhance the thermal deformation temperature and the mechanical property of the ABS resin, and reduce the molding shrinkage and the linear expansion coefficient.

The glass fiber reinforced ABS has good application value in the field of household appliances due to good processing performance, dimensional stability and tensile strength, such as axial flow, cross flow and centrifugal fan blades in air conditioners. The performance of the glass fiber reinforced ABS directly influences the quality of the air conditioner, and is closely related to the daily life of people. As the living standard of people increases, the performance of household appliances is more severe, and the performance of air conditioners is not only limited to temperature adjustment, but also desired to provide an indoor air purification effect. However, there is currently no good solution. Therefore, the development of the glass fiber reinforced composite material which has excellent mechanical properties and can efficiently release negative oxygen ions is very important, and the glass fiber reinforced composite material has a huge market space.
