Abstract

The invention relates to a low-surface treatment rusty rust inhibiting primer for hot galvanized steel. The low-surface treatment rusty rust inhibiting primer is characterized by comprising a component A and a component B based on 100 parts of the low-surface treatment rusty rust inhibiting primer, wherein the component A is prepared by blending, stirring and grinding 15 to 40 parts of film-forming resin solution, 10 to 30 parts of pigment, 4 to 12 parts of rust corrosion transforming agent and 0.5 to 1 part of anti-settling agent; the component B comprises 20 to 30 parts of mixed curing agent and 15 to 35 parts of mixed solvent; and the mass ratio of the component A to the component B is 5+/-0.5:1. The components of the primer reduce the using amount of dimethylbenzene and have very good bonding force with the surface of the hot galvanized steel, wherein the adhesive force is 1 grade. The coating has high flexibility and corrosion resistance and can be used for rusty coating on the surface of the rusty hot galvanized steel.

Description

[technical field] [0001] The invention relates to paints, in particular to a low-surface-treated rust-preventing primer for hot-dip galvanized steel. [Background technique] [0002] Low surface treatment coatings are mainly aimed at rusty coatings that are impossible to fully reach the sandblasting level of Sa2. The active substance passivates the rust layer and converts it into a stable non-toxic filler to achieve low surface treatment; and uses a resin with good permeability to seal the rust layer to achieve a protective effect. [0003] Hot-dip galvanizing is an anti-corrosion method that is widely used in steel structures. In order to prevent the surface of the steel plate from being corroded and prolong its service life, a layer of metal zinc is coated on the surface of the steel plate. This galvanized thin steel plate is called galvanized Plate, hot-dip galvanized. However, after the hot-dip galvanized layer is corroded, when it is protected again, because the surfac...
