Problems solved by technology

[0002] Applying varnish on the metal surface can play a decorative role on the metal. The varnish can effectively prevent dust and dirt, have high gloss and high wear resistance, and can protect the metal. However, the traditional varnish Varnish and traditional painting process will produce a lot of VOCs, which is harmful to the environment and the body

Embodiment 1

[0018] Step 1, pretreatment: use clean water to remove dust from the steel plate;

[0019] Step 2, surface treatment: using a degreasing agent to remove oil stains on the steel plate, cleaning the steel plate with a water clearing agent, and treating the surface of the steel plate with chromium-free passivation;

[0020] Step 3, painting treatment: apply varnish on the outside of the steel plate, and bake and cure the varnish to form a varnish layer;

[0021] Step 4, apply the top coat: apply the top coat on the varnish;

[0022] Step 5, anti-corrosion treatment: apply a corrosion-resistant material on the inner side of the steel plate, and solidify the corrosion-resistant material to form a corrosion-resistant layer.

[0023] Wherein, the varnish of step three consists of the following parts by weight: leveling agent A 0.48%, butyl acetate 4.5%, polyaspartic acid ester resin 86%, cellulose acetate butyrate 9%, drying 0.02% agent A, 68% isocyanate curing agent and 32% butyl ...

Abstract

The invention provides a surface transparent finishing process free of VOCS, and belongs to the field of finishing processes. The process comprises the following steps: pretreating a steel plate; treating the surface of the steel plate; coating the outer side of the steel plate with finishing varnish and then baking and curing, wherein the finishing varnish is composed of 0.48% of a leveling agentA, 4.5% of butyl acetate, 86% of polyaspartic acid ester resin, 9% of cellulose acetate butyrate, 0.02% of a drier A, 62% of an isocyanate curing agent and 38% of butyl acetate; coating a finish paint on the surface of the finishing varnish; and performing preservative treatment. The process has the beneficial effects that the emission of VOCs can be greatly reduced by the finishing varnish, VOCsare not generated after the finishing paint is smeared through a new process, and the harm to the environment and human bodies is greatly reduced.

Description

technical field [0001] The invention belongs to the field of varnishing technology, and in particular relates to a surface transparent varnishing process that does not generate VOCs. Background technique [0002] Applying varnish on the metal surface can play a decorative role on the metal. The varnish can effectively prevent dust and dirt, have high gloss and high wear resistance, and can protect the metal. However, the traditional varnish Gloss paint and traditional painting techniques will produce a large amount of VOCs, which is harmful to the environment and the body. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming of prior art, provide a kind of surface transparent varnish process that does not produce VOCs, varnish of the present invention can make the emission of VOCs reduce greatly, pass through new technology to smear after varnish again without Produce VOCs, greatly reducing the harm to the environment and ...
