Abstract
The invention discloses a modified plastic and preparation method thereof, which is composed of raw materials according to the following weight percentages: 14.5-15.5% of carbon fibers, 7.0-8.0% of boron fibres and rest amounts of F46. Carbon fiber, boron fibre and F46 are uniformly mixed according to the weight percentages, and are melt at 370-390 DEG C for 6-8 minutes, and are fully stirred for five minutes, and are carried out by plastic extrusion and compaction. The invention has the beneficial effects that the pump body made from the materials can be used under the medium condition of 200 DEG C, strong acid with pH<1 and 30% of solid content, and the product is suitable for conveying strong acid mediums at high temperature with high solid content in the chemical industry, metallurgy, etc.
Description
Technical field
The present invention relates to a kind of plastics, more specifically, it relates to a kind of modified plastics and preparation method.
Background technology
For industries such as chemical industry, metallurgy, the pump made from metal material, the life-span is substantially not long, has directly affected user's normal operational cost.Need badly for carrying high temperature, strong acid, high solid content medium to develop the type material for pump in the industries such as chemical industry, metallurgy.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of intensity high, the life-span is long, is applicable to the modified plastics of pump for the industries such as chemical industry, metallurgy.
The object of the invention is to be achieved through the following technical solutions: this modified plastics, is comprised of following materials by weight percentage: carbon fiber 14.5～15.5%, boron fibre 7.0～8.0%, all the other are F46.
As preferably: by weight percent: carbon fiber 15%, boron fibre 7.5%, all the other are that F46 forms.
The preparation method of this modified plastics, carbon fiber, boron fibre, F46 mix by weight percentage through 370～390 ℃ of meltings 6～8 minutes and after fully stirring 5 minutes extrusion molding compacting.
The invention has the beneficial effects as follows: using this material to make pump housing can resistance to 200 ℃, pH value < 1 strong acid and solid content reach 30% medium operating mode, is applicable to carry high temperature, strong acid, high solid content medium in the industries such as chemical industry, metallurgy.
Embodiment
Below in conjunction with embodiment, the present invention is described further.Although the present invention is described in connection with preferred embodiment, should know, do not represent to limit the invention in described embodiment.On the contrary, the present invention is by alternative, modified version and the equivalent contained in the scope of the present invention that can be included in attached claims restriction.
This modified plastics, by weight percent: carbon fiber 15%, boron fibre 7.5%, all the other are that F46 forms.Several starting material are mixed to extrusion molding compacting after (370～390) ℃ melting (6～8) minute is also fully stirred 5 minutes by weight percentage.F46 is the multipolymer of tetrafluoroethylene and R 1216, is perfluoroethylene-propylene (FEP), and the content of R 1216 approximately 15% left and right, is the material modified of tetrafluoroethylene, is current material.
Mechanics Performance Testing: tensile strength is 5～6 times of F46, reaches (150～180) Mpa; 1000 mill amounts while turning are 0.03g.
Chemical property test: erosion resistance and F46 are suitable.
This is material modified mainly for carrying high temperature, strong acid, high solid content medium to develop in the industries such as chemical industry, metallurgy.Using this material to make pump housing can resistance to 200 ℃, pH value < 1 strong acid and solid content reach 30% medium operating mode, is applicable to carry high temperature, strong acid, high solid content medium in the industries such as chemical industry, metallurgy.
