Problems solved by technology

[0004] However, acrylate polymer itself is thermoplastic, lacks cross-linking points on linear molecules, and is difficult to form a three-dimensional network cross-linked film, so its water resistance and stain resistance are poor, it is easy to become brittle at low temperature, and easy to stick at high temperature

Abstract

The invention discloses an acrylic coating and a preparation method thereof, and particularly relates to an organic-silicon organic-fluorine modified acrylic heavy anti-corrosion coating and a preparation method thereof. The invention provides the organic-silicon organic-fluorine modified acrylic heavy anti-corrosion coating which has free TDI content less than 0.15% after blended, is capable of reducing the pollution hazard on the environment and has preferable film-forming property and a preparation method thereof, aiming at overcoming the defects of the prior art. The organic-silicon organic-fluorine modified acrylic heavy anti-corrosion coating comprises the following components in parts by weight: 40-60 parts of fluorine-silicon modified acrylic resin, 0.2-0.5 part of dispersing agents, 10-20 parts of pigments, 10-20 parts of fillers, 0.2-0.5 part of defoaming agents, 0.2-0.5 part of levelling agents, 10-15 parts of solvents and 8-14 parts of aliphatic polyurethane curing agents, wherein the proportion sum is 100 parts.

Description

technical field [0001] The invention relates to an acrylic paint and a preparation method thereof, in particular to an organosilicon-organic fluorine modified acrylic heavy-duty anticorrosion paint and a preparation method thereof. Background technique [0002] Acrylic resin has the characteristics of light color, high transparency, bright and full, tough coating film, strong adhesion, corrosion resistance, etc., and is a commonly used coating material. However, because acrylic resin has certain defects in specific occasions, such as hardness, weather resistance, pollution resistance, solvent resistance, poor mechanical properties and high cost, etc., its further application is limited. [0003] In recent years, with the continuous improvement and development of polymerization technology and people's emphasis on environmental protection products, the modification of acrylic resin has attracted widespread attention. Scholars at home and abroad have carried out a lot of in-de...
