Problems solved by technology

[0003] At the same time, in order to improve the mechanical properties such as surface strength and impact strength of water-based epoxy coatings, inorganic fillers such as silica and bentonite are often added to them. The progress of the coating is poor, there is deposition, and at the same time, the surface of the coating film is uneven and there are particles, which reduces the quality of the finished product

Abstract

The invention discloses anti-leakage waterborne epoxy coating which is prepared from the following raw materials in parts by weight: 0.8 to 1 of fatty acid diethanol amide, 0.1 to 0.2 of nonyl phenol,1 to 2 of oleic acid polyoxyethylene ester, 2 to 3 of calcium ricinoleate, 0.7 to 1 of naphthenic soap, 1 to 2 of zinc dialkyl dithiophosphate, 4 to 6 of magnesium silicate, 6 to 8 of hydroxyethyl cellulose, 4 to 7 of polyethylene glycol adipate and 100 to 120 of epoxy resin E51. The coating disclosed by the invention has the advantages of good uniform stability, strong leakage resistance and excellent comprehensive performance.

Description

Technical field [0001] The invention belongs to the field of coatings, and specifically relates to an anti-leakage water-based epoxy coating and a preparation method thereof. Background technique [0002] A large amount of organic solvents such as benzene, toluene, xylene, etc. are added to traditional solvent-based paints, most of which are flammable and explosive toxic substances. Long-term inhalation of the human body can cause fatigue, loss of memory and neurological diseases. In severe cases, it can cause cancer. . Organic volatiles are directly discharged into the atmosphere. Under ultraviolet radiation, photochemical smog and acid rain will be generated, which cause serious pollution to the atmosphere and are considered to be one of the main sources of air pollution. With the strengthening of society's awareness of environmental protection and labor protection, countries around the world have successively formulated laws and regulations to limit VOC emissions. Research a...
