Problems solved by technology

But their disadvantage is that they are all solvent-based products, with high organic solvent content, and sometimes fire accidents in the drying tunnel
For traditional amino baking varnishes, the diluting solvents are mostly xylene, toluene and other solvents, and the volatilization of benzene solvents is increasingly worrying about the impact on personal injury and air quality at the operation site.

Abstract

The invention provides a water soluble tape paint, which belongs to the technical field of paint. The water soluble tape paint comprises water soluble acrylic resin, an aqueous and oily dispersant, a polyether modified siloxane defoamer, a nano-gas phase silicon dioxide anti-settling agent, a paint, dimethylethanolamine, de-ionized water, a cosolvent, a fluorocarbon modified polyacrylate flatting agent, and water soluble amino-acid resin through proportioning. The content of organic solvent in the water soluble tape paint is low; all of the organic solvents are friendly to the environment, which fall beyond the scope of solvents restricted by the state. The lacquer films can be cured quickly and have excellent physical and mechanical properties without needing catalyzers, which can reach and be higher than the index of the traditional solvent.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-soluble coating for measuring tapes, and at the same time provides a preparation method for the water-soluble coating for measuring tapes. Background technique [0002] Tape measure coating is a kind of special coating, which is widely used in the coating of measuring instruments such as tape measure. sex etc. With the increasing requirements of international and domestic users for environmental protection performance, it is also necessary to ensure that the coating does not contain heavy metals and control and reduce the content of organic solvents. [0003] Traditional varieties include acrylic amino paints and epoxy-modified alkyd amino paints. For example, Chinese patent 200510095173.7 discloses a "preparation method for lead-free tape measure paint", which does not use lead-containing raw materials, especially yellow pigments, and the lead content complies with EN-...
