NOVELTY - Preparing anti-corrosion and anti-cracking board involves adding the aqueous resin, acrylic emulsion, wetting agent, methyl n-amyl ketone, dispersant, and graphene oxide into a high-speed mixer for high-speed mixing and stirring. The stirring speed is 200-500 revolutions/minute, the stirring time is 20-30 minutes, and the mixture is obtained. The obtained mixture is put into the reactor, and added defoamer, water, film forming aids and preservatives to make it fully mixed and agitated, and heated and mixed for 40-60 minutes at a temperature of 45-60 degrees C, and the mixing speed is 500-600 revolutions/minute to obtain anticorrosive and environmentally friendly paint for use. The rough processing is performed on the plate to be treated, cut the plate to the required size, polished the surface, and performed soot blowing and slag removal on the surface for use. The plates are send to glycerin in batches for soaking, and soaked them at 30-45 degrees C for 4-5 hours. USE - Method for preparing anti-corrosion and anti-cracking board. ADVANTAGE - The prepared has a high anti-corrosion effect and anti-cracking effect, can adapt to low temperature and high temperature environments, and effectively avoids the cracking phenomenon caused by thermal expansion and contraction, and with aqueous resin as the main material, it has a good environmental protection effect when used, and not harm the environment and the human body. DETAILED DESCRIPTION - Preparing anti-corrosion and anti-cracking board involves adding the aqueous resin, acrylic emulsion, wetting agent, methyl n-amyl ketone, dispersant, and graphene oxide into a high-speed mixer for high-speed mixing and stirring. The stirring speed is 200-500 revolutions/minute, the stirring time is 20-30 minutes, and the mixture is obtained. The obtained mixture is put into the reactor, and added defoamer, water, film forming aids and preservatives to make it fully mixed and agitated, and heated and mixed for 40-60 minutes at a temperature of 45-60 degrees C, and the mixing speed is 500-600 revolutions/minute to obtain anticorrosive and environmentally friendly paint for use. The rough processing is performed on the plate to be treated, cut the plate to the required size, polished the surface, and performed soot blowing and slag removal on the surface for use. The plates are send to glycerin in batches for soaking, and soaked them at 30-45 degrees C for 4-5 hours, and after soaking, they are cooked, and defatted plates are obtained after the cooking is finished and cooled naturally. The board is washed with water soaking at a temperature of 10-40 degrees C, soaked for 8-10 minutes, and then rinsed with pure water, then sprayed the water pressure at 0.12-0.17 megapascal and the temperature at 20-30 degrees C to get the cleaned board. The board is dried, and used an air compressor to perform high-pressure blowing treatment on its surface. The anticorrosive and environmentally friendly paint is sprayed with primer on the board through dynamic spraying equipment, which helps to smooth the paint surface, and carried out the main paint spraying treatment on the board, and the main paint spraying for 2-3 times, each time it is sent to the dust-free constant temperature baking room for 10-15 minutes for 145-185 degrees C baking curing treatment, and sent to a cool place to dry naturally to obtain an anti-corrosion and anti-cracking board.
