Abstract

The invention relates to the technical field of heavy anti-corrosion coatings, in particular to an acrylic acid modified polysiloxane coating and a preparation method thereof. The coating comprises a first ingredient and a second ingredient. The first ingredient comprises, by weight, 20-30% of acrylic resin containing reactive hydrogen functional groups, 10-20% of polysiloxane intermediates containing phenyl / methyl functional groups, 20-30% of pigments and fillers, 0.1-0.5% of rheological additives, 5-20% of composite environment-friendly solvents, 0.2-1% of flatting agents, 10-15% of methyl methacrylate and 3-7% of butyl acrylate. The second ingredient is prepared from the following components in parts by weight: 20 to 30 percent of organic silicon resin containing active hydroxyl groups, 5 to 10 percent of organic siloxane containing reactive epoxy propoxy groups and methoxyl groups and 0.1 to 0.5 percent of a catalyst. The polysiloxane resin is added, so that the coating can effectively maintain color and gloss for a long time, and can be used as a part of a high-performance anti-corrosion coating system; various functional groups are provided for the system, mutual catalytic reaction is achieved, and the crosslinking density is high. The product has the characteristics of long adaptation period, high drying speed, good chemical resistance and the like.

Description

technical field [0001] The invention relates to the technical field of heavy-duty anti-corrosion coatings, in particular to an acrylic modified polysiloxane coating and a preparation method thereof. Background technique [0002] Polysiloxane coatings are divided into two types: acrylic polysiloxane and epoxy polysiloxane. The gloss and color permanence of acrylic-modified polysiloxane coatings are significantly better than typical polyurethane topcoats, and the gloss and color retention is also better than that of first-generation epoxy-modified polysiloxane topcoats. better. In addition, acrylic-modified polysiloxane coatings have the same corrosion resistance and slightly better mechanical properties than conventional epoxy technology. At present, there are two main types of acrylic polysiloxane: one is the addition and hydrolysis condensation between the acrylic resin containing double bonds and siloxane, and the other is the hydrolytic interaction between the acrylic r...
