Embodiment 1

[0011] Embodiment 1 provides a special high-strength polypropylene material for electric tool shells, which is composed of the following components by weight: polypropylene: 62.8%; environmentally friendly glass fiber: 33.1%; reinforcing agent: 3.4%; antioxidant: 0.25% ; Coupling agent: 0.45%.

[0012] First weigh the polypropylene, reinforcing agent, antioxidant, and coupling agent according to the proportion, and then mix them in the mixer at a low speed for 10 minutes. The mixer adopts low-speed mixing and is made of stainless steel. The gap between the stirring blade and the cylinder wall should be less than 0.5 cm , the mixing effect of raw and auxiliary materials should be visually observed that the various particles, powders, and liquids are basically uniform, without obvious agglomerates or agglomerations, and then placed naturally for 6 hours to allow them to fully react before use; twin-screw extruders use 36-40 aspect ratio , medium-strength shearing; environmentall...

Abstract

The invention discloses a high strength polypropylene material, which is composed of following components in percentage by weight: 60 to 80% of polypropylene, 20 to 40% of environmentally friendly glass fiber, 3 to 6% of enhancer, 0.1 to 1.0% of antioxidant, and 0.1 to 1.0% of coupling agent. The high strength polypropylene material is specially used for manufacturing an electric tool shell; the performance of the high strength polypropylene is similar with that of a common reinforced nylon material; moreover, the raw materials are easily available; the material cost and injection production cost are both lower than those of the reinforced nylon material; the high strength polypropylene material can be 100% recovered and used after the electric tool expires; moreover, the high strength polypropylene meets the environment protection requirements, and the market competitiveness is improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically to a high-strength polypropylene material. The invention also relates to a method of making such a high strength polypropylene material. technical background [0002] At present, the production and consumption of electric tools is huge, and its production bases are mainly concentrated in mainland China. Most of the materials used in current electric tool housings are 30% glass fiber reinforced nylon 6 materials, because this material has good mechanical strength and processability. However, the price of this material is relatively high, and the proportion is relatively large. These shortcomings have been plagued by power tool manufacturers. [0003] Relatively speaking, the price of polypropylene material is only about half of the price of nylon 6 material, and because its specific gravity is about 20% lower than that of nylon material, its cost advantage is huge. At t...
