Abstract

The invention provides a polypropylene composite material for an air conditioner wind wheel, which comprises the following components in parts by weight: 30-85.7% polypropylene, 2-8% metallocene polypropylene elastomer, 10-50% long glass fiber, 0.1-2% heat stabilizer, 0.1-2% nucleating agent, 2-6% compatibilizer, 0.1-2% other additives. The invention adopts polypropylene as the main material, and adds metallocene polypropylene elastomer to modify the polypropylene, so that the prepared composite material has excellent performance of high temperature resistance and low temperature resistance; and long glass fiber is added to improve the impact strength of the finished product. At the same time, the interaction of thermal stabilizers, additives, nucleating agents, and compatibilizers is also coordinated to improve the stability of the material and better meet the production needs of air-conditioning wind wheels.

Description

technical field [0001] The invention relates to the field of materials, in particular to a polypropylene composite material for an air conditioner wind wheel and a preparation method thereof. Background technique [0002] The air conditioner is the air conditioner (Air Conditioner), which refers to the equipment that uses manual means to adjust and control the temperature, humidity, cleanliness, flow rate and other parameters of the ambient air in the building / structure. With the improvement of material life, air conditioners have become a necessary household appliance for every household. [0003] Air conditioners generally include cold source / heat source equipment, cold and hot medium transmission and distribution systems, terminal devices and other auxiliary equipment. Among them, the wind wheel is one of the core components of the air conditioner. At present, chopped glass fiber reinforced SAN (styrene acrylonitrile) and chopped glass fiber reinforced AS (acrylonitrile-...
