Abstract

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. Including ingredient 1 and ingredient 2, the ingredient 1 includes by weight: 20-30% of acrylic resin containing active hydrogen functional group, 10-20% of polysiloxane intermediate containing phenyl / methyl functional group, pigment and filler 20-30%, rheology aid 0.1-0.5%, compound environmental protection solvent 5-20%, leveling agent 0.2-1%, methyl methacrylate 10-15%, butyl acrylate 3-7%. The second ingredient includes, in parts by weight: 20-30% of organosiloxane resin containing active hydroxyl groups, 5-10% of organosiloxane containing reactive glycidoxy and methoxy groups, 0.1-10% of catalyst 0.5%. By adding polysiloxane resin, the present invention can effectively maintain color and luster for a long time, and is used as a part of high-performance anti-corrosion coating system; the present invention provides a variety of functional groups for the system, which catalyze each other and react with each other, and have high crosslinking density. The product has the characteristics of long adaptation period, fast drying and good chemical resistance.

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 acrylic polysiloxane and epoxy polysiloxane. The gloss and color persistence 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 traditional epoxy resin technology. At present, there are mainly two kinds of acrylic polysiloxanes: one is the addition and hydrolytic condensation between acrylic resin containing double bond and siloxane, and the other is hydrolytic cross-linking between acrylic resin polysilo...
