Abstract

The invention discloses long-acting heavy-duty anticorrosive system finishing coat and a preparation method thereof, belongs to the technical field of coating, and solves the technical problem of relatively long curing time of existing long-acting heavy-duty anticorrosive system finishing coat. The finishing coat comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 30-40 parts of polysiloxane, 10-20 parts of acrylate, 3-5 parts of talc powder, 1-3 parts of bentonite, 1-3 parts of a wetting dispersant, 1-3 parts of a rheological additive, 1-3 parts of a defoaming agent and 5-10 parts of a moisture scavenger; and the component B comprises the following components in parts by weight: 20-30 parts of aminopropyltriethoxysilane and 1-3 parts of tetra-n-butyl titanate. The finishing coat prepared by the method has short curing period, is convenient in actual application, and has excellent comprehensive performance and extremely low VOC content.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a long-acting heavy-duty anti-corrosion system topcoat and a preparation method thereof. Background technique [0002] The current long-term heavy-duty anti-corrosion system topcoat uses acrylic polysiloxane resin as the base material, and uses an acrylic resin modified polysiloxane intermediate with a low relative molecular weight containing functional side groups. The side groups mainly contain hydroxyl groups. , glycidyl ester group, etc., the functional side group in the acrylic resin reacts with the alkylaminosiloxane curing agent and the polysiloxane intermediate under the action of the catalyst. [0003] Adopting this curing method takes a long time to cure, and it is not very convenient to use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a long-acting heavy-duty anti-corrosion system topcoat and its prep...
