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 a quick-drying elastic paint and a method for using the same, comprising a main agent A component, a curing agent B component and a dilute solvent C component, wherein the A component includes: Butanone, n-butyl acetate, butanone, mixed dibasic acid ester, elastic resin, polyester resin and wear-resistant wax slurry, etc.; B component is curing agent resin, C component includes ethyl acetate, diacetone alcohol, Isopropyl alcohol, organotin driers and organotin complexing aids. Compared with the prior art, the present invention has the advantages of fast drying and curing speed and long activation period, and can flexibly adjust the elasticity of the elastic paint by adjusting the ratio of the organotin drier in the main agent A component and the diluent C component. Pot life and drying speed.

Description

technical field [0001] The invention relates to the technical field of elastic paint, in particular to a quick-drying elastic paint and a using method thereof. Background technique [0002] At present, elastic paints have been applied in many fields because of their good touch and elasticity, such as furniture paints, automotive interior paints, 3C electronic paints and other applications that often come into contact with the human body. [0003] Pipeline spraying occupies a large proportion in the coating process, but when line spraying, the baking time of the workpiece on the line depends on the length of the line body and the speed of the water in the baking section. Due to the limitation of spraying construction, the spraying speed is constant for workpieces of the same size and similar shape, resulting in a constant flow speed of the wire body, and increasing the length of the wire body means increasing the workshop site and equipment investment. Therefore, increasing ...
