Special odorless modified acrylic acid stoving varnish coating

Abstract

The invention discloses a special odorless modified acrylic acid stoving varnish coating, and relates to the technical field of coatings. The special odorless modified acrylic acid varnish stoving varnish coating comprises the following components in parts by weight: 60 parts of HE61, 11 parts of nano black paste, 0.5 part of fumed silica, 0.2 part of BYK333, 0.1 part of TEGO410, 0.2 part of TEGO245, 5.7 parts of DBE, 2 parts of Z-6040, 13 parts of Bayer 3175 curing agent, 3 parts of Cytec 303, 0.3 part of a cooling agent and 4 parts of 704 epoxy resin. According to the special odorless modified acrylic acid stoving varnish coating, the resin is selected from high-solid-content and low-viscosity resin, a high-boiling-point and low-odor type solvent is selected as a solvent of the matrix resin, during film forming at the high temperature of 160-180 DEG C, paint film forming reaction is fast, volatile gas is little, solvent volatilization is little, the odorless and environment-friendly effects are achieved during production and construction, The varnish coating can be applied to industrial stoving varnish, household appliance stoving varnish, electric cookers, electric frying pans and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special modified acrylic varnish paint with clean odor. Background technique [0002] The baking varnish is to spray several layers of paint on the base that has been polished to a certain degree of roughness, and then baked at a high temperature to set the shape. Now the conventional baking varnish is used in the production process to produce toxic volatile gases due to the volatility of the solvent, and the flash point of the solvent in the work production It is easy to cause safety accidents, is flammable and explosive, affects the safety of production, and harms the health of workers. The high-temperature baking gas volatilizes and smells pungent, which has a great impact on the air environment; [0003] In the market, the main resins of conventional amino baking varnishes are low-solid content resins with large solvent volatilization and low solvent boiling point. Resin r...

[0002] The baking varnish is to spray several layers of paint on the base that has been polished to a certain degree of roughness, and then baked at a high temperature to set the shape. Now the conventional baking varnish is used in the production process to produce toxic volatile gases due to the volatility of the solvent, and the flash point of the solvent in the work production It is easy to cause safety accidents, is flammable and explosive, affects the safety of production, and harms the health of workers. The high-temperature baking gas volatilizes and smells pungent, which has a great impact on the air environment;

[0003] In the market, the main resins of conventional amino baking varnishes are low-solid content resins with large solvent volatilization and low solvent boiling point. Resin resins have small molecular weights during production reactions and a small amount of monomer residues, and irritating odors are emitted during high-temperature film-forming reactions of paints. Conventional amino baking varnish has a pungent taste of volatile free formaldehyde; for this reason, we propose a special modified acrylic bright oil baking varnish with clean odor
