Baking varnish stripping composition, preparation method and applications thereof

Abstract

The present invention discloses a baking varnish stripping composition, which comprises, by mass, 2.5-5% of urea, 1-3% of sodium metasilicate pentahydrate, 10-17% of butyl acetate, 2-5% of phenol, 0-1% of benzotriazole, and the balance of water. According to the present invention, the baking varnish stripping composition has advantages of low cost, less pollution, short paint stripping time, strong penetration, no corrosion on the substrate, strong paint stripping effect, no dead angle and no residue, can completely separate the coating material and the substrate within a short time, can be used for the stripping of a variety of different baking varnishes, and can provide the technical support for the development of industrial cleaning agents.

Description

technical field [0001] The invention belongs to the field of industrial cleaning, and more specifically relates to a baking paint stripping composition and a preparation method and application thereof. Background technique [0002] Because the baking varnish has the characteristics of bright colors, no stagnation, not easy to fade, strong personalization, can be matched with floor tiles, wall tiles, furniture and fabrics, scrub resistance, fine surface, no dirt, easy (resistance) scrubbing, etc. Therefore, baking varnish has been applied to various fields now. However, due to the aging of the paint film or failure to meet the standards during the spraying process, this workpiece needs to be recycled and re-sprayed, so the old paint film needs to be removed. In the past, mechanical methods were usually used, such as knife scraping, manual removal, etc. This method is not only time-consuming and laborious, but also easy to cause mechanical damage to the collective surface.

Problems solved by technology

In the past, mechanical methods were usually used, such as knife scraping, manual removal, etc. This method is not only time-consuming and laborious, but also easy to cause mechanical damage to the collective surface. In recent years, many different types of paint removers have appeared on the market. Although they save time and labor than mechanical stripping, they have many limitations, such as limited types of stripping and slow stripping speed

So far, the research on baking paint remover is still in its infancy, mainly because the adhesion of baking paint is particularly strong, and common paint removers are difficult to remove
