Embodiment 1

[0031] The preparation method of solvent-resistant environmental protection water-based paint of the present invention, the method comprises the following steps:

[0032] 1) Acetal resin composite oxide preparation:

[0033] The ingredients are formulated according to the following weight percentages: 5% calcium oxide, 15% waste glass, 16% sodium oxide, 0.6% cerium oxide, and the rest is silicon oxide; the particle size of each material is 1-4mm;

[0034] Mix the materials evenly, then put them into the crucible in the heating furnace and heat to 1430 degrees, take out the crucible after 12 minutes of heat preservation, pour the molten inorganic materials into a steel mold and cool to room temperature; then crush and grind the obtained composite oxide to 10-20 microns;

[0035] The acetal resin is heated at 195 degrees to obtain a molten substance, then the above-mentioned composite oxide is added to the molten acetal resin and stirred evenly, and naturally cooled to room tem...

Embodiment 2

[0042] The preparation method of solvent-resistant environmental protection water-based paint of the present invention, the method comprises the following steps:

[0043] 1) Acetal resin composite oxide preparation:

Abstract

The invention provides an environment-friendly waterborne coating with solvent resistance and a preparation method. The material has a stable corrosion protection property. The preparation method is simple in process and low in production cost and is suitable for industrial production. The coating is prepared from the following components by weight percent: 2-6% of montmorillonite, 2-6% of polyethylene glycol, 5-10% of organic silicone emulsion, 6-10% of titanium dioxide powder, 10-14% of acetal resin composite oxide, 0.1-0.5% of barium sulfate, 40-50% of synthetic resin, 5-8% of epoxy resin and the balance of water, wherein the weight ratio of acetal resin to composite oxide in acetal resin composite oxide is (1-3) to 10.

Description

Technical field: [0001] The invention belongs to the field of coatings, and relates to a solvent-resistant environmental protection water-based coating and a preparation method. Background technique: [0002] Application No. CN200710047452.5 provides a water-based coating for steel strips, which is uniformly mixed with epoxy-modified polyester resin, cross-linking agent, pigment, curing catalyst and water. [0003] The above-mentioned water-based paint for steel strip is mixed by the following components, and the content of each component and weight % is: component weight % epoxy modified polyester resin 70-80, crosslinking agent 6-8, pigment 8 -15, curing catalyst 1-2, deionized water 4-6, described epoxy modified polyester resin, is polymerized under the effect of organotin catalyst by polyhydric alcohol mixture and polybasic acid mixture, then adds epoxy resin and Trimellitic anhydride, after continuing the polymerization reaction under the action of benzylamine catalyst...
