Abstract

The invention discloses a special air conditioner wind wheel material with high rigidity, high heat resistance and low shrinkage, and a preparation method of the special air conditioner wind wheel material. The special air conditioner wind wheel material is composed of the following materials by weight: 33-68% of polypropylene resin, 5-10% of interface bonding agent, 15-35% of alkali-free glass fiber, 10-20% of mineral powder, 0.1-1% of nucleating agent, 1-5% of crystal whisker, 0.1-1% of antioxygen, and 0.1-2% of lubricant. The rigidity index of the wine wheel material is up to 7000Mpa, the molding shrinkage is 0.6%, both the rigidity index and the molding shrinkage are about the same as those of a universal SAN material wind wheel, and the best advantage is that the molding liquidity, the heat resistance and the toughness are all better than those of the SAN material wind wheel. All selected materials of the invention meet the environmental requirement of European Union ROSH. The raw materials of the special air conditioner wind wheel material are easy to get, the energy consumption is low, the machine wear rate is small, the cost is low, the recycling is easy, and the special air conditioner wind wheel material is suitable for replacing the SAN material wind wheel.

Description

【Technical field】 [0001] The invention relates to a patented material for an air-conditioning wind wheel and a preparation method thereof, in particular to a special material for an air-conditioning wind wheel with high rigidity, high heat resistance and low shrinkage and a preparation method thereof. 【Background technique】 [0002] The wind wheel is one of the core components of the air conditioner, which is directly related to the air supply volume, mute effect and energy consumption of the air conditioner. Among them, the selection and manufacture of wind wheel materials are the key factors affecting its quality. At present, the material widely used in the manufacture of air conditioner wind wheels is glass fiber reinforced SAN material, but the cost of glass fiber reinforced SAN material is expensive, the process is complicated, the manufacturing energy consumption is high, the wear and tear of the machine is large, and it is difficult to reuse and recycle.
