Abstract

The invention discloses quick-drying polyurethane transparent primer which belongs to the technical field of primer. The primer includes, by weight, the following raw materials: 30-70 parts of short oil alkyd resin, 25-55 parts of anatase type titanium dioxide, 30-40 parts of zinc stearate, 2-3 parts of talc powder of 1250 meshes, and 1-3 parts of organic soil. The quick-drying polyurethane transparent primer of the invention is the primer prepared by dispersing glass flakes at a high concentration in a base material; the used base materials includes epoxy, the anatase type titanium dioxide, unsaturated resin, the zinc stearate, and the like; and due to its strong isolation capability, the primer is suitable for steel structures with serious corrosion in the sea and ocean wave splash zones.

Description

technical field [0001] The invention belongs to the technical field of primers, in particular to a quick-drying polyurethane transparent primer. Background technique [0002] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. If the quality of the topcoat is good, the primer can be used. This statement is wrong, because the functions of the topcoat and the primer are different. The topcoat is more focused on the final decoration and appearance effect, while the primer is focused on improving the adhesion and anti-corrosion function. , Alkaline resistance, etc. [0003] Nowadays, anti-corrosion primers have become an important new force in the field of primers. Anti-corrosion primers are playing an...
