Problems solved by technology

The current market products have disadvantages such as slow drying time, hardness lower than 2H, poor adhesion, poor weather resistance, low gloss, etc.
[0005] Due to the technical defects and product quality limitations of the above two products, as well as their relatively high production formula costs, the promotion and development of industrial water-based metallic paints have been greatly restricted.

Abstract

The invention relates to environment-friendly water-based nano varnish and a preparation method thereof. The preparation method comprises the following steps: putting 10-30 parts by weight of water-based nano activation base material in a reaction kettle, slowly adding 1-5 parts by weight of coupling agents and 1-5 parts by weight of aids in sequence, standing for 8-48 hours for curing, and putting the obtained cured material, 50-70 parts by weight of emulsion and 10-30 parts by weight of water in an activation kettle to undergo group activating, crosslinking and grafting, thus obtaining a product under the conditions of nitrogen or argon protection, pressure of 0.1-3Mpa and activation time of 8-48 hours, wherein the temperature range of the activation kettle is controlled to be 30-80 DEG C. Compared with the prior art, the environment-friendly water-based nano varnish has the advantages of complete water-based environment-friendly system, no environmental pollution, complete water-based low-temperature self-drying system, no safety hazards such as burning and explosion, high adhesion to metal materials, good hardness, strong scratch resistance and the like.

Description

technical field [0001] The invention relates to coatings, in particular to an environment-friendly water-based nano-varnish and a preparation method. Background technique [0002] The rapid development of the global metal industry has driven the rapid development of the metal paint market. Metal paint has a wide range of uses in different industries and fields. Metallic paints are divided into two categories, solvent-based metallic paints and water-based metallic paints. Among them, solvent-based metallic paints have many problems such as environmental pollution, hidden dangers in production safety, and human health threats, and will be gradually replaced by environmentally friendly water-based metallic paints in the future. . At present, the industrial water-based metallic paint products on the market include water-based metallic baking paint and self-drying metallic paint. [0003] Among them, water-based metal baking paint is mainly made of amino resin, alkyd resin, epo...
