Embodiment 1

[0026] The raw material that present embodiment adopts and consumption see table 1, wherein:

[0027] The polyacrylic resin is a high-crystalline homopolypropylene, which comes from LOTTE Company, and its brand name is PP JSS-370N.

[0028] The compatibilizer is PP grafted maleic anhydride, which comes from Arkema Company, and the brand name is CA100.

[0029] Alkali-free glass fiber comes from OWENS CORNING company.

[0030] The mineral powder is 1250 mesh mica powder.

[0031] The whiskers are calcium sulfate whiskers modified by silane coupling agent.

[0032] The antioxidants are 1010 and 168.

[0033] The preparation method of the special material for the air-conditioning wind wheel is as follows:

[0034] After mixing polypropylene, compatibilizer, mineral powder, whiskers, antioxidant, etc. evenly, put them into the main feeding port of the twin-screw extruder, and put the alkali-free glass fiber into the side feeding port, and adopt the weak shearing process to car...

Embodiment 2

[0036] See Table 1 for the raw materials and consumption used in this embodiment, and the raw materials other than mineral powder are all the same as in Example 1.

[0037] In this example, the mineral powder is a mixture of 1250 mesh mica powder and 5000 mesh talc powder in a mass ratio of 7:3.

[0038] In this example, the preparation method of the special material for the air-conditioning wind wheel is the same as in Example 1, and will not be repeated here.

Embodiment 3

[0040] See Table 1 for the raw materials and consumption used in this embodiment, and the raw materials other than mineral powder are all the same as in Example 1.

[0041] In this example, the mineral powder is a mixture of 1250 mesh mica powder and 10000 mesh talc powder in a mass ratio of 7:3.

[0042] In this example, the preparation method of the special material for the air-conditioning wind wheel is the same as in Example 1, and will not be repeated here.

Abstract

The invention belongs to the field of macromolecular alloy materials and particularly relates to a special material for wind wheels of air conditioners and a preparation method for the special material. The special material for the wind wheels of the air conditioners is prepared from the following ingredients in percentage by weight: 45% to 70% of polypropylene resin, 3% to 5% of compatibilizer, 15% to 25% of alkali-free glass fibers, 5% to 15% of mineral powder, 5% to 10% of crystal whiskers and 0.1% to 1.5% of antioxidant, wherein the polypropylene resin is high-crystallinity homopolymerized polypropylene. According to the special material and the preparation method therefor, the high-crystallinity homopolymerized PP is adopted and is added with appropriate glass fibers, mineral powder, crystal whiskers and compatibilizer, so that the rigidity of the material is effectively improved; and the mineral powder in the formula is used in a manner of being compounded with the crystal whiskers, so that the conformation of a molecular chain of polypropylene is restricted, the forming shrinking percentage and warping tendency are lowered, and the dimensional stability of the material is improved.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a special material for air-conditioning wind wheels and its preparation. Background technique [0002] The wind wheel is one of the core components of air conditioners. At present, glass fiber reinforced SAN (styrene acrylonitrile) materials are mainly used, but the cost is high, the process is complicated, and recycling is difficult. [0003] Polypropylene resin (PP) has wide sources, low density, easy processing, low cost, and easy recycling, which can better meet the social requirements for environmental protection. In the prior art, polypropylene resin is also used as a raw material, but the finished product finally has a large shrinkage rate and low impact strength. Contents of the invention [0004] The technical problem to be solved by the invention is to overcome the deficiencies of the prior art and provide an improved special material for the wi...
