Problems solved by technology

Among them, glass fiber is the most widely used, but glass fiber has comparative advantages in terms of specific strength, service temperature, chemical stability (especially in alkaline medium), vibration damping performance, heat resistance and sound insulation characteristics. Large limitations, and the production process of glass fiber is easy to produce dust, three wastes and other hazards to the natural environment. In addition, boron dioxide, which is in short supply, needs to be used in the manufacture of glass fiber, and the production cost of glass fiber is relatively high.

Embodiment 1

[0053] Get 69 parts by weight of polypropylene resin, 30 parts by weight of basalt fibers with a single fiber diameter of 9 μm and a length of 3 millimeters in which 30 parts by weight of silane are processed, and 0.3 parts by weight of polypropylene wax as a lubricant, 0.02 parts by weight as Calcium stearate of filler, 0.03 parts by weight of calcium hydroxide as stabilizer, 0.05 parts by weight of 264 (DTBP) as anti-aging agent and 0.2 parts by weight of tert-butylperoxyethane as antioxidant, 0.1 parts by weight Part of antioxidant 1010 and 0.3 part by weight of antioxidant DLTP were mixed in a kneader and pelletized with a screw extruder with a full-range screw at 250°C. Thus, a polypropylene resin composition was obtained. The obtained pellets were molded into flexural modulus test strips (according to ASTM D 790 specification) with an injection molding machine, and their flexural strength and flexural modulus properties were measured. The experimental results are shown ...

Abstract

The present invention offers a polypropylene resin composite. The said polypropylene resin composite contains polypropylene resin and basalt fiber. Specially, setting the total amount of polypropylene resin composite as 100 units, the said polypropylene resin composite contains 50 to 95 units of polypropylene resin, and 50 to 5 units of corresponding basalt fiber. Moreover, the said basalt fiber is 3 to 10 mm in length, and 9 to 17 mu m in diameter. The present invention also offers the preparation method of polypropylene resin composite and the fan made by using the composite. The polypropylene resin composite prepared by the present invention, overcomes the existing technical defect, and has high elastic modulus and better impact performance and chemical stability; meanwhile, it has very high heat and sound proofing properties, and is suitable for various industrial components, especially the fan of air-condition.

Description

technical field [0001] The invention relates to a polypropylene resin composition, a preparation method thereof and a fan prepared therefrom. More specifically, the present invention relates to a polypropylene resin composition containing basalt fiber as a reinforcing component, a method for its preparation, and a fan. Background technique [0002] In the prior art, as a general-purpose thermoplastic resin, polypropylene (PP) has better heat resistance than polyethylene (PE); its melting point reaches about 164°C, and it can be used for a long time at 100-120°C. In addition, polypropylene It also has excellent corrosion resistance and electrical insulation, and its mechanical properties (including tensile strength, compressive strength, hardness) are better than high-density polyethylene (HDPE), and it also has outstanding rigidity. Polypropylene is easy to process, and most of it is used for injection molding. In addition to daily necessities, it can also be used to manufa...
