A kind of paint production method

Abstract

The invention discloses a method for producing an oil paint, and relates to the field of chemical processes. The method comprises the following steps: feeding, premixing, grinding, mixing a paint, introducing oxygen, filtering and the like, namely adding materials to a twin-cylinder high-speed disperser in opening mixing during feeding; firstly adding 1 / 5 of polyurethane acrylic resin to a first cylinder to render; adding a little of conductive carbon black, chlorinated paraffin, magnetic iron powder, zeolite powder and nickel powder, adding part of polyurethane acrylic resin at an interval of 1 minute, and completely adding the residual polyurethane acrylic resin for 3-4 times; adding a mixed solution of double distilled water, butanol, an organic silicone resin fluid and an isocyanate adhesive to a second cylinder, and carrying out hydrolytic crosslinking reaction; and adding nano powder, and carrying out catalytic reaction, mixing the materials which are processed in the first cylinder and the second cylinder at the ratio, thus various defects of the oil paint can be improved; resources can be reasonably distributed; and the method is economic and applicable.

Description

technical field

[0001] The invention relates to the field of chemical technology, in particular to a paint production method. Background technique

[0002] Paint, generally speaking, is a material that can be coated on the surface of the object to be coated and can form a continuous film that is firmly attached, whether it is a traditional coating product that uses natural substances as raw materials or a modern development that uses synthetic chemical products as raw materials. The coating products are all organic chemical polymer materials, and the formed coating film belongs to the polymer compound type. According to the classification of modern chemical products, coatings belong to fine chemical products, and modern coatings are gradually becoming a multifunctional product. Engineering materials are an important industry in the chemical industry. The application number is CN201310088201.7, which discloses a paint production process, including paint powder, polyvinyl buty...

Embodiment 1

[0019] A kind of paint production method, described production method comprises the steps:

[0020] (1) Feeding and pre-mixing: Put the materials into a one-machine double-cylinder high-speed disperser with stirring, first add 1 / 5 polyurethane acrylic resin to the tank as a primer, and then add conductive carbon black with less content, After chlorinated paraffin, NdFeB magnet powder, zeolite powder and nickel powder, add part of polyurethane acrylic resin every 1min, and the remaining polyurethane acrylic resin is added in 4 times, wherein, conductive carbon black accounts for 1% of the total amount, chlorination Paraffin wax accounts for 4% of the total amount, magnet powder accounts for 0.5% of the total amount, zeolite powder accounts for 4% of the total amount, and nickel powder accounts for 4% of the total amount. To antistatic effect, chlorinated paraffin plays the role of flame retardant and protects personal safety. Adding magnet powder into the paint makes the paint ...

Embodiment 2

[0026] Embodiment 2: the rest is the same as the above-mentioned embodiment 1, the difference is that in step (1), the NdFeB magnet powder is replaced by AlNiCo magnet powder, and in step (1), the Zinc oxide nanopowder is replaced by tin oxide nanopowder. In the step (4), the actual temperature of the heating oxygen is 120°C. In the step (3), the pigment is titanium dioxide, which accounts for the total amount of the paint. 1% of the amount.

Embodiment 3

[0027] Embodiment 3: the rest is the same as the above-mentioned embodiment 1, the difference is that in step (1), the NdFeB magnet powder is replaced by ferrite magnet powder, and in the step (1), the Zinc oxide nanopowder is replaced by tin oxide nanopowder. In the step (4), the actual temperature of the heating oxygen is 100°C. In the step (3), the pigment is titanium dioxide, which accounts for the total amount of the paint. 1% of the amount.

[0028] In the above three examples, the antistatic performance of the paint reaches 108~12 / Ωcm, the paint has weak magnetic properties after testing, the flame retardancy reaches V0 level, and the flame retardancy is excellent. The activity of heating oxygen is marked with citric acid (CAA value) The activity is 1~3s; the activity expressed by the iodine absorption value is 80~120 (mgI2 / 100gMgO), the oxygen activity is high, the paint is placed for 48 hours after opening, there is no whitening phenomenon, and it has good adhesion on...
