Embodiment 1

[0036] The carbon fiber reinforced polypropylene composite material is prepared from the following components in parts by weight:

[0037]

[0038] Among them, in the mixture of polypropylene glycol and polyvinyl alcohol, the mass ratio of polypropylene glycol and polyvinyl alcohol is 3:1; in the processing aid, the antioxidant 1010:EBS:silane coupling agent is 3:4 :3.

[0039] The preparation method is as follows:

[0040] (1) Treatment of carbon fiber: At room temperature, carbon fiber bundles pass through a low-temperature plasma treatment box at a speed of 2m / s, and are packed in a box for later use.

[0041] (2) Stir and mix the mixture of polypropylene, polypropylene glycol and polyvinyl alcohol and processing aids evenly according to the proportion, then add nano-silicon carbide whiskers at a temperature of 80° C., and stir for 15 hours to obtain a mixed base material;

[0042] (3) Add the carbon fiber treated in step (1) and the mixed base material in step (2) int...

Abstract

The invention discloses a carbon fiber reinforced polypropylene composite material, which is prepared from the following components in parts by weight: 10 to 17 parts of carbon fiber, 2 to 6 parts of nano silicon carbide whisker, 60 to 70 parts of polypropylene, 20 to 30 parts of the mixture of polypropylene glycol and polyvinyl alcohol and 0.5 to 2 parts of processing aid. The invention also discloses a preparation method of the composite material. The composite material provided by the invention can be used as a produced plastic filter plate; not only is the price lower, but also various performance indexes are all higher than those of an imported filter plate; physical and chemical properties can completely accord with a national quality standard at a normal temperature; the carbon fiber reinforced polypropylene composite material has the tensile strength which is 85MPa or above, the bending strength which is 110MPa or above and the IZOD notched impact strength which is 25KJ / m<2> or above; meanwhile, the composite material has the service life which is also longer than that of the imported filter plate, can be used as a substitute of an imported product, and has a wide market development prospect.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber composite materials, in particular to a carbon fiber reinforced polypropylene composite material, and also relates to a preparation method of the composite material. Background technique [0002] Filter press was used in chemical production in the early 18th century, and it is still widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. Press filtration is generally realized by a filter press to extract the solids in the mixed liquid to achieve solid-liquid separation. The filter press is a mechanical device that uses a special filter medium to dialysis the liquid. [0003] Vertical filter press is currently the most advanced new process of liquid-solid separation with high technological content in the world. At present, only a few countries such as Finland and the United States have successively developed and used it. I...
