Environment-friendly and low-carbon rotation rust paint and preparation method thereof

Abstract

The invention discloses environment-friendly and low-carbon rotation rust paint prepared from a mixed solution and deionized water. The weight percentage ratio of the mixed solution to deionized water is between 19 to 3 and 21 to 1. The mixed solution is prepared from, by weight, 60%-70% of waterborne acrylic emulsion, 10%-20% of tartaric acid solutions, 5%-6% of polyvinyl alcohol solutions, 5%-8% of sodium pentachlorophenate solutions, 3%-5% of sodium nitrite solutions, 3%-5% of phosphoric acid and 0.2%-0.3% of tributyl phosphate. A preparation method of the paint includes the steps of evenly stirring tartaric acid solutions and sodium chlorite solutions, sequentially adding waterborne acrylic emulsion, polyvinyl alcohol resin, sodium nitrite solutions, phosphoric acid and tributyl phosphate to be evenly stirred, and finally conducting dilution. The environment-friendly and low-carbon rotation rust paint and the preparation method have the advantages that derusting does not need to be conducted on steel structure products before the rotation rust paint is coated, performance of an inertia coating formed after coating reaches the performance of a coating formed by solvent type paint, and the use requirements are met.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to an environmentally friendly low-carbon autorotation rust coating used on steel structure products and a preparation method for preparing the environmental protection low-carbon autorotation rust coating. Background technique [0002] At present, the coatings used on steel structure products mainly use organic solvent-based coatings. Organic solvent-based coatings contain a large amount of volatile organic compounds (VOC for short), most of which are flammable and explosive toxic substances, which contain a variety of Carcinogenic substances, it can damage the liver, kidney, brain, nervous system, irritate the eyes and respiratory tract, cause skin allergies, cause headaches, sore throat and fatigue, and have a serious impact on the human ecological environment. With the restrictions on volatile organic compounds in various countries' environmental protection regulations, the c...

Problems solved by technology

As an environmentally friendly water-based coating, the content of volatile organic compounds is very low, so the coating of steel structure products will develop in the direction of environmentally friendly water-based coatings, but the common water-based coatings currently on the market are formed after coating The coating cannot meet the performance requirements of the coating formed after the solvent-based coating is applied, and cannot meet the use requirements

[0003] In addition, during the painting process, since the steel structure products are easy to rust, it is necessary to perform derusting treatment such as shot blasting or sand blasting on the rusted steel structure products before painting the steel structure products, and then the steel structure products Coating, shot blasting or sandblasting will produce dust pollution, and the construction environment is very harsh. In addition, due to construction conditions, if the steel structure products after derusting cannot be painted in time, secondary rusting problems will easily occur, so that It is necessary to derust the rusted steel structure products again, which greatly increases the workload of the construction personnel, and the cost and energy consumption are high
