Embodiment 1

[0014] A plastic for injection molding, comprising the following raw materials in parts by weight: 30 parts of ethyl 3-ethoxy propionate, 25 parts of epoxy resin, 10 parts of aluminum oxide, 10 parts of silicon dioxide, 12 parts of glass fiber, 8 parts of titanium dioxide, 6 parts of anti-aging masterbatch.

Embodiment 2

[0016] A plastic for injection molding, comprising the following raw materials in parts by weight: 40 parts of ethyl 3-ethoxy propionate, 35 parts of epoxy resin, 14 parts of aluminum oxide, 14 parts of silicon dioxide, 16 parts of glass fiber, 14 parts of titanium dioxide, 10 parts of anti-aging masterbatch.

Embodiment 3

[0018] A plastic for injection molding, comprising the following raw materials in parts by weight: 35 parts of ethyl 3-ethoxy propionate, 30 parts of epoxy resin, 12 parts of aluminum oxide, 12 parts of silicon dioxide, 14 parts of glass fiber, 11 parts of titanium dioxide, 8 parts of anti-aging masterbatch.

[0019] The preparation method of plastics for injection molding described in the above Examples 1 to 3 is as follows: (1) Add the above-mentioned raw materials in parts by weight into the reaction kettle and mix them evenly; The granulator granulates to obtain the above-mentioned plastic granules for injection molding.

[0020] The chemical properties of silicon dioxide are relatively stable, which can increase the heat resistance and wear resistance of the plastic described in the invention. Insoluble in water and does not react with water. It is an acidic oxide and does not react with common acids. Gaseous hydrogen fluoride reacts with silicon dioxide to form gaseou...

Abstract

The invention discloses plastic for injection molding is prepared from, by weight, 30 to 40 parts of ethyl 3-ethoxypropionate, 25 to 35 parts of epoxy resin, 10 to 14 parts of aluminum oxide, 10 to 14parts of silicon dioxide, 12 to 16 parts of glass fiber, 8 to 14 parts of titanium dioxide and 6 to 10 parts of anti-aging master batch. The plastic has the beneficial effects that a product finallyprepared from the plastic has good wear resistance and heat resistance, the preparation method is simple, and the cost is low; the plastic is easier to store, stable in physical property and chemicalproperty and long in storage time.

Description

technical field [0001] The invention belongs to the field of injection molding, and in particular relates to a plastic for injection molding. Background technique [0002] In order to better insulate the winding, the outer wall between the two phases of the stator is generally covered with plastic, and different materials are used according to the different uses of the insulating board. For example: polyvinyl chloride board, epoxy resin board, paper offset plate, cloth offset plate, bakelite board, various resin boards, etc. [0003] For existing plastics used for injection molding, there are problems of low wear resistance and poor heat resistance. Contents of the invention [0004] The technical problem to be solved by the present invention is: for the existing plastics used for injection molding, there are problems of low wear resistance and poor heat resistance. Therefore, a plastic for injection molding is provided. [0005] In order to solve the problems of the te...
