Abstract

The invention discloses epoxy anti-corrosive finish paint, which is a double-component epoxy finish paint consisting of component A and component B; the component A consists of the following ingredients: 35 to 45 percent by weight of medium-molecular weight epoxy resin, 8 to 10 percent by weight of dimethylbenzene, 3 to 5 percent by weight of n-butyl alcohol, 1.0 to 1.4 percent by weight of anti-settling agent, 8.5 to 10.5 percent by weight of filler, 10 to 20 percent by weight of pigment, 0.5 to 1.5 percent by weight of dispersant, 0.2 to 0.4 percent by weight of defoaming agent and 0.5 to 1.5 percent of multifunctional auxiliary; the component B consists of the following ingredient: 8 to 12 percent by weight of epoxy curing agent; and the weight ratio of the component A to the component B is (2 to 6):1. By the manner, the invention provides the epoxy anti-corrosive finish paint and a preparation method thereof, the method is simple, the production cost is low, thick film type epoxy finish paint can be produced, and the paint film has excellent physical properties, such as adhesive force, flexibility, wear resistance and impact resistance, and also has excellent corrosion resistance and weather fastness.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an epoxy anticorrosion topcoat and a preparation method thereof. Background technique [0002] Paint is widely used as an anti-corrosion coating, whether it is the surface of mechanical equipment, frames, bridges and cement buildings produced in various factories, or the surface of public facilities such as viaducts, utility poles, and road guardrails in cities. Paints of various colors are used as the anti-corrosion layer, which not only plays the role of anti-corrosion, but also has a more beautiful effect. [0003] At present, as an important coating, epoxy paint is widely used in the coating and anticorrosion process due to its low cost and good adhesion. However, epoxy paint is currently used because of its poor weather resistance and easy to fade , so it can only be used as a primer for a large number of metal products. [0004] With the continuous increase of the demand for coati...
