Embodiment 1

[0027] A kind of preparation method of water-based inorganic zinc-rich primer of the present invention comprises the following steps:

[0028] (1) Preparation of component A: first mix alkali metal silicate, aluminum-modified silica sol, partially deionized water, water glass, and additives thoroughly; then add the above-mentioned inorganic pigments, organic bentonite, and whisker reinforcement The material and all the other deionized water are fully mixed, and the gained liquid is passed through a 70 mesh sieve to obtain the A component of the water-based inorganic zinc-rich primer of the present invention;

[0029] (2) Preparation of component B: fully mix zinc powder, nano-zinc oxide, nano-titanium dioxide, composite iron-titanium powder, and curing agent to obtain component B of the water-based inorganic zinc-rich primer of the present invention;

[0030] The particle size of organic bentonite is 300-400 mesh.

[0031] The proportioning ratio of each raw material in Examp...

Abstract

The present invention relates to an aqueous inorganic zinc-rich prime coat, which comprises a component A and a component B, wherein the component A comprises 35-65 parts of an alkali metal silicate, 10-15 parts of an aluminum modified silica sol, 15-30 parts of deionized water, 5-25 parts of an inorganic pigment, 1-3 parts of organic bentonite, 2-8 parts of water glass, 2-8 parts of a crystal whisker reinforced material and 1-3 parts of an auxiliary agent, and the component B comprises 50-70 parts of zinc powder, 2-6 parts of nanometer zinc oxide, 1-3 parts of nanometer titanium dioxide, 2-6 parts of composite iron-titanium powder and 2-7 parts of a curing agent. The aqueous inorganic zinc-rich prime coat of the present invention has characteristics of chemical corrosion resistance, high temperature resistance, low temperature resistance, strong adhesion and strong impact resistance.

Description

technical field [0001] The invention relates to a coating composition and a preparation method thereof, in particular to a water-based inorganic zinc-rich coating composition and a preparation method thereof. Background technique [0002] Corrosion is the main form of steel failure. In order to suppress and prevent the occurrence of corrosion and reduce economic losses, protective measures need to be taken. For a long time, people have adopted multiple technical means for this purpose. Among them, coating the steel surface with an anti-corrosion coating to isolate the corrosive medium from the metal substrate has become one of the most economical, reliable, effective and commonly used methods. [0003] The current coating anti-corrosion method is to cover another metal or non-metal protective layer on the surface of steel materials through physical, chemical, and electrochemical processes, and use this protective layer to prevent or slow down metal corrosion. Zinc protect...
