Problems solved by technology

[0002] At present, the conventional two-component PU wood paint is mainly used in the manufacture and decoration of ordinary furniture, but the modern electrical product market needs a two-component PU paint used for finishing wooden square speakers. , it needs to be moved frequently during use, it is often affected by temperature changes, it is easy to crack, it is easy to be impacted and wear-resistant, so special requirements are put forward for the paint used for coating, which requires extremely high adhesion and high wear resistance. Scratch resistance, strict resistance to temperature changes, moisture and water resistance, decorative (water drop effect)
Conventional two-component PU wood coatings can only meet the general coating requirements of furniture companies or home decoration. For the coating of square speakers, either the performance of the paint film cannot meet the requirements, or the cost is too high to meet large quantities. industrial production

Abstract

The invention relates to the field of polymer materials, in particular to a coating technology, and especially relates to a double-component PU (Polyurethane) water drop effect decorative paint and a preparation method thereof. The double-component PU water drop effect decorative paint comprises three components of a main solvent, a curing agent and a diluent, wherein the main solvent comprises the following component by weight: synthetic fatty acid modified alkyd resin with a 70% solid content, epoxy resin, 10% organic bentonite anti-settling pulp, polyamide wax anti-settling pulp, color paste for PU, heavy calcium carbonate, glass powder, matte powder, an adhesive force accelerating agent, a wet dispersing agent, a functional assistant agent and a solvent. The double-component PU water drop effect decorative paint has the advantages of high solid content, high adhesion, excellent wear and scratching resistant performance, good temperature difference change resistant performance, water proofing, strong stereoscopic impression, obvious water-drop effect, protrusion without sinking and smooth hand feel.

Description

technical field [0001] The present invention relates to the field of polymer materials, in particular to coating technology, and in particular to a two-component PU (polyurethane paint) and its preparation method. Strength, wear resistance, scratch resistance, water resistance, temperature difference resistance, and impact resistance. After the paint is sprayed with a pressurized container spray gun, it can show the decorative effect on the black glass plate like water droplets. Full and not dry and sunken, smooth to the touch, with a unique decorative effect. This two-component PU water drop effect decorative paint is mainly used in the manufacture and coating of square speakers, and can also be used for decoration. Background technique [0002] At present, the conventional two-component PU wood paint is mainly used in the manufacture and decoration of ordinary furniture, but the modern electrical products market needs a two-component PU paint used for finishing wooden sq...
