Embodiment 1

[0026] Example 1 Manufacturing process of high fluorine-containing anti-seepage conductive anti-corrosion topcoat

[0027] Preparation of Component A

[0028] Put the modified high-fluorine-containing fluorocarbon resin into the batching tank, and start high-speed stirring. Then add butyl acetate, bentonite, 104S, then add rutile titanium dioxide, pigment, wax slurry, and slowly increase the speed of the mixer to 800r / min.

[0029] Start the main engine to sand and grind until the fineness is qualified, and send it to the paint mixing tank. The ambient temperature during grinding is not higher than 40°C.

[0030] Turn on the paint mixing tank and stir to add the remaining resin, 2810, 306 additives, defoamer, and static conductive powder ①②, and clean the batching tank and sand mill equipment with the remaining solvent. After passing the inspection, filter and pack.

Abstract

The invention discloses a high-fluorine impermeable static-conductive fluorocarbon finish paint, which is composed of a component A and a component B. Specifically, the component A is composed of 40-65 parts of modified high-fluorine fluorocarbon-containing resin, 10-35 parts of rutile type titanium dioxide, 1-5 parts of pigment, 0.1-1.0 part of bentonite, 0.1-0.5 part of a BYK-104S dispersant, 0.1-0.6 part of a BYK-306 leveling agent, 0.1-0.6 part of a 2810 rheological assistant, 1-3 parts of wax slurry, 5-12 parts of butyl acetate, 0.1-1.2 parts of an antifoaming agent 2185, 2-10 parts of conductive mica and 2-10 parts of polyaniline; and the component B comprises 30-80 parts of modified polyisocyanate and 30-80 parts of xylene; wherein all the components are in parts by mass. The high-fluorine impermeable static-conductive fluorocarbon finish paint is mainly applied to corrosion prevention of the inner wall of a container type storage tank for storing and transporting dangerous chemicals, has excellent chemical resistance, and particularly resists permeation of small molecular amines. According to the invention, various expected paint colors can be obtained by adjusting the typeand dosage of the pigment as required.

Description

technical field [0001] The invention relates to the field of coating science and technology, in particular to an anti-corrosion finish paint for the inner wall of a container-type storage tank for storing and transporting dangerous chemicals. [0002] technical background [0003] With the acceleration of economic globalization, the demand for storage and transportation of international goods, especially hazardous chemicals, has increased. Shipping hazardous chemicals in containerized tanks is a low-cost option for international freight. Due to the strong permeability of some hazardous chemicals such as small molecule amines, alcohols, aldehydes and other volatile organic compounds, they are extremely destructive to the anti-corrosion coating on the inner wall of container storage tanks. Volatile organic compounds generate static electricity during storage and transportation, which is likely to cause safety accidents. Therefore, the anti-corrosion coating on the inner wall ...
