Formula of primer-topcoat combined inorganic rust conversion high-temperature-resistant anti-rust paint and making technology

Abstract

The invention discloses a formula of a primer-topcoat combined inorganic rust conversion high-temperature-resistant anti-rust paint and a making technology.A small quantity of an organosilicon polymer solution and water-based inorganic film former silicate are adopted as base materials, an anti-rust agent, a rust conversion agent, multiple pigments and fillers and auxiliaries are added, and after dispersion, grinding and blending, the paint is obtained.The single-component paint achieves primer-topcoat combination and has the advantages of rust conversion, passivation and construction with rust and the advantages of being resistant to high temperature, free of toxins or smells, large in adhesive force, good in anti-rust effect and capable of achieving construction easiness and convenience.The situation that for a traditional bi-component anti-rust paint, matching products such as a thinning agent and a curing agent are needed is changed; the adhesive force, weather resistance and use universality are improved; complex processes such as strict polishing or shot blasting or chemical derusting needed by a base face are omitted; the defects of toxicity and harmfulness, environmental pollution and the like are overcome; the complex process of primer coating, middle coating and top coating is simplified.

Description

technical field [0001] The invention relates to the field of inorganic coating macromolecular polymers, in particular to the formulation and production technology of the bottom-surface-integrated inorganic rust-transferring, high-temperature-resistant and anti-rust coating. Background technique [0002] Antirust coatings in the prior art are divided into oily and water-based. Oil-based anti-rust paint makes it difficult to remove the greasy surface of the material. Oil-based antirust paint is easy to use and low in price, but because it contains toxic substances such as nitrite and chromate, it is harmful to operators. Rust requirements. Water-based metal anti-rust paint uses polyurethane, acrylic acid, silicate, etc. as film-forming materials and adds red lead, zinc powder, iron oxide, etc. to make two-component or multi-component coatings, which require primer, mid-coat, top coat and other processes Complex, narrow scope of use, strict requirements on the base surface, ...

Problems solved by technology

Oil-based antirust paint is easy to use and low in price, but because it contains toxic substances such as nitrite and chromate, it is harmful to operators. Rust requirements

Water-based metal anti-rust paint uses polyurethane, acrylic acid, silicate, etc. as film-forming materials and adds red lead, zinc powder, iron oxide, etc. to make two-component or multi-component coatings, which require primer, mid-coat, top coat and other processes Complex, narrow scope of use, strict requirements on the base surface, the base surface must undergo strict sandblasting, shot blasting, pickling and other derusting processes before use, the construction requires a long time, high cost, toxic and harmful

Although there are also products in the market that claim to be inorganic anti-rust coatings, after analysis, they are only a hybrid coating that uses silicate and a large amount of acrylic or resin as the film-former plus zinc powder or iron red, etc. The coating film has poor water resistance, It is easy to crack and rust and so on, these are the problems that the existing anti-rust coatings cannot overcome
