preparation example Construction

[0011] A preparation method of plastics for concrete mixing tanks, the preparation method comprising:

[0012] a. Mix and refine phenolic resin, white carbon black, polyethylene, styrene, plasticizer, antioxidant and kaolin to make a masterbatch;

[0013] b. Vulcanizing the vulcanizing agent and the masterbatch, and extruding to obtain a plastic.

[0014] In the present invention, the amount of each component can be selected within a wide range, but in order to make the obtained plastic have excellent strength, toughness and corrosion resistance, preferably, relative to 100 parts by weight of phenolic resin, white carbon The consumption of black is 120-140 parts by weight, the consumption of polyethylene is 80-90 parts by weight, the consumption of styrene is 40-60 parts by weight, the consumption of plasticizer is 8-10 parts by weight, and the consumption of antioxidant is 10-15 parts by weight, and the amount of kaolin is 4-9 parts by weight.

[0015] In the present invent...

Embodiment 1

[0025] 1) Mix phenolic resin (molecular weight: 6000), white carbon black, polyethylene, styrene, phthalic acid, sodium sulfite and dicumyl peroxide according to the ratio of 100:120:80:40:8:10:4 Ratio, at a temperature of 150°C, smelt for 1 hour to obtain a masterbatch;

[0026] 2) Put the vulcanizing agent in the masterbatch at a ratio of 0.4:100, and vulcanize for 2 hours at a temperature of 200°C to obtain plastic A.

Abstract

The invention discloses plastic for a concrete mixing tank and a preparation method thereof. The preparation method comprises the following steps: a, mixing phenol-formaldehyde resin, white carbon black, polyethylene, styrene, a plasticizer, an antioxidant and kaolin to prepare a master batch; b, carrying out vulcanization treatment on a vulcanizing agent and the master batch, and extruding and molding to obtain the plastic. The plastic for the concrete mixing tank, prepared by the method disclosed by the invention, has excellent strength, toughness and corrosion resistance; raw materials are easy to obtain and the preparation method is simple.

Description

technical field [0001] The invention relates to a plastic, in particular to a plastic for a concrete mixing tank and a preparation method thereof. Background technique [0002] In the field of construction, plastics are widely used because of their ease of manufacture and low cost, and they are favored by manufacturers. The traditional metal mixing tank has a short service life and requires frequent maintenance and maintenance, which is expensive. Compared with metal mixing tanks, the advantages of plastic mixing tanks are very obvious. However, because the strength, toughness and corrosion resistance of plastic mixing tanks have not yet met the special production needs of the existing market, the material of plastic mixing tanks is the research and development direction and focus of personnel in the field. Contents of the invention [0003] The object of the present invention is to provide a plastic for concrete mixing tank and its preparation method. The plastic for con...
