Problems solved by technology

[0004] However, for the adjustment of various abnormal conditions during the construction process, the thinned paint needs to maintain a certain period of activation period, otherwise, the curing time of the paint is too fast, which will cause a lot of waste of paint and the hidden danger of equipment damage

Abstract

The invention relates to quick-drying elastic paint and a using method thereof. The quick-drying elastic paint is prepared from a main agent component A, a curing agent component B and a diluting solvent component C. The component A is prepared from an organic tin drier, methylisobutylketone, n-butyl acetate, butanone, mixed dibasic acid ester, elastic resin, polyester resin, wear-resistant wax slurry and the like; the component B is a curing agent resin, and the component C comprises ethyl acetate, diacetone alcohol, isopropanol, an organic tin drier and an organic tin complexing aid. Compared with the prior art, the drying and curing speed is high, the activation period is long, and the activation period and the drying speed of the elastic paint can be flexibly adjusted by adjusting theproportion of the organic tin drier in the main agent component A and the diluent component C.

Description

technical field [0001] The invention relates to the technical field of elastic paint, in particular to a quick-drying elastic paint and its application method. Background technique [0002] At present, elastic paint has been applied in many fields due to its good touch and elasticity, such as furniture paint, automotive interior paint, 3C electronic paint and other application fields that are in frequent contact with the human body. [0003] The assembly line spraying occupies a large proportion in the coating process, but when the assembly line is sprayed, the baking time of the workpiece on the line depends on the length of the line body and the flow speed of the baking section. Due to the limitation of spraying construction, the spraying speed is certain for workpieces of the same size and similar shape, which leads to a certain flow speed of the line body, and increasing the length of the line body means increasing the investment in workshop space and equipment.
