[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 rust-resistant epoxy resin paint. The rust-resistant epoxy resin paint is composed of the following raw materials in parts by weight: 2-3 parts of sodiumpotassiumsilicate, 0.01-0.02 part of p-toluenesulfonic acid, 300-400 parts of modified epoxyemulsion, 4-5 parts of sorbitan monooleate, 6-8 parts of trichloroisocyanuric acid, 0.7-1 part of 2-mercaptobenzimidazole and 0.8-1 part of lauryl dimethylamineoxide. According to the rust-resistant epoxy resin paint disclosed by the invention, through continuous reactions performed in a reaction kettle, the production cost is greatly reduced, the reaction process is shortened and the energy consumption is reduced. The tributyl borate added into the rust-resistant epoxy resin paint has good rust resistance, and the quality of the finished product paint can be effectively improved.
Description
technical field [0001] The invention belongs to the field of paint, and in particular relates to an antirust epoxy resin paint and a preparation method thereof. Background technique [0002] A large number of organic solvents such as benzene, toluene, xylene, etc. are added to traditional solvent-based paints, most of which are flammable, explosive and toxic substances. Long-term inhalation of the human body will cause fatigue, memory loss, and neurological diseases. In severe cases, it can cause cancer . Organic volatiles are directly discharged into the atmosphere, and under the radiation of ultraviolet rays, photochemical smog and acid rain will be generated, causing serious pollution to the atmosphere, and are considered to be one of the main sources of air pollution. With the strengthening of the whole society's awareness of environmental protection and labor protection, countries around the world have successively formulated laws and regulations to limit VOC emissions...
