Lacquer painting technology for plate surface of teaching green plate

Abstract

The invention belongs to the technical field of coating of a plate surface of a teaching green plate, and discloses a lacquer painting technology for a plate surface of a teaching green plate. The lacquer painting technology is performed according to the following formula comprising 15%-30% of epoxy resin, 5%-10% of silicon carbide, 20%-35% of phthalocyanine green, 35%-42% of an X-7 epoxy diluent and 1%-5% of rare earth. The brushing technological process comprises the following steps: 1, adding the epoxy resin into the X-7 epoxy diluent, and soaking the epoxy resin in the X-7 epoxy diluent; 2, after soaking, adding the rare earth, the silicon carbide and the phthalocyanine green, and performing sufficient and uniform stirring so as to obtain a mixture for standby application; 3, uniformly spraying the mixture in a compounding ratio to a galvanized steel plate; 4, placing the galvanized steel plate after being sprayed with the mixture in an infrared ray baking booth, drying the galvanized steel plate, then after the surface of the galvanized steel plate is dried, raising the baking temperature to 280 DEG C, and when green which is bright in color appears on the surface of the galvanized steel plate, stopping drying. Through the formula and the spraying technology, the lacquer surface adhesive force of the plate surface of the teaching green plate can be improved, and the teaching green plate has the characteristics of being high in intensity and durable.

Description

technical field [0001] The invention belongs to the technical field of painting the surface of teaching green boards, and in particular relates to a painting process for the surface of teaching green boards. Background technique [0002] The predecessor of the teaching board is a blackboard. The traditional blackboard is simply to apply black paint on the surface of a hard object such as a flat wooden board or cement board, and write with chalk after the black paint dries. [0003] With the progress of society, the teaching green board gradually replaces the original wooden or cement blackboard. The surface of the green board is mostly made of alloy steel plate with wear-resistant coating, which has the characteristics of low reflection on the board surface, smooth writing, and is not easy to fade. , less dust and other advantages, however, the existing teaching green board still has some disadvantages in function, first of all, the composition of the existing teaching green...

[0003] With the progress of society, the teaching green board gradually replaces the original wooden or cement blackboard. The surface of the green board is mostly made of alloy steel plate with wear-resistant coating, which has the characteristics of low reflection on the board surface, smooth writing, and is not easy to fade. , less dust and other advantages, however, the existing teaching green board still has some disadvantages in function, first of all, the composition of the existing teaching green board is mostly the combination of steel plate and wear-resistant coating, which is wear-resistant after long-term use The coating is easy to fall off, resulting in uneven board surface and unsmooth writing. In view of the above, as a technician in this industry, it is very necessary to develop a painting process for the teaching green board surface, which can be achieved through the paint ratio and the coating process. Improvement to improve the strength of the paint surface of the teaching green board, so that the teaching green board can achieve higher strength and more durable characteristics
