Abstract

The invention discloses a general aseptic base coat and a production method thereof and aims at providing an aseptic base coat which has strong popularity, can be widely used for a plurality of base materials, such as aluminum, steel, titanium, stainless steel, other alloy materials, and the like, is convenient to use and ensures that a solidified coat film formed by the general aseptic base coat has favorable mechanical performance and excellent protection performance. The aseptic base coat is formed by the combination of an A component and a B component according to the weight parts of 100:(20-25), wherein the B component comprises a polyamide resin curing agent and a polyamide resin thinning agent, and the solid content of the B component is 40 percent; and the A component comprises the following components based on parts by weight: 40-50 epoxy resin, 20-30 aseptic pigment, 15-20 titanium dioxide, 0.1-0.3 carbon block pigment, 0.3-1 dispersing agent, 0.2-0.5 flatting agent, 0.2-0.5 defoaming agent and 35-40 thinning agent. The aseptic base coat can be used on different materials, is convenient to use and easy to manage.

Description

technical field [0001] The invention relates to a paint, in particular to an anti-corrosion primer commonly used in aluminum, steel, titanium and alloy substrates and a preparation method thereof. Background technique [0002] Various metal substrates such as automobiles, airplanes, tanks and other skin surfaces are subjected to water, hot water, acid, alkali, lubricating oil, fuel oil and other media all the year round. Not only requires excellent bonding between the primer and the substrate, but also requires excellent compatibility between the primer and the aliphatic polyurethane enamel. The formed coating system not only has a good protective effect on the substrate, but also has good weather resistance and comprehensive performance. [0003] At present, the primers used in China are divided into anti-corrosion primers for non-ferrous metals such as aluminum alloys, ferrous metals such as steel, and other metal protective primers. For products composed of multiple mate...
