Abstract
A kind of anticorrosive putty paint for applying on metal surfaces of vehicles and machine tools is composed of inorganic material and organic polymer compounds. This paint uses strong alkalinity cement, which can form chemical bond with ferrous and ferric ions, to combine with polymer latex. It can effectively prevent the penetration of chloride ion, water and oxygen, so that it possesses good anticorrosive, antiscale and weatherability.
Description
The present invention relates to a kind of corrosion-proof putty coatings that is applied to the metallic surface, especially be widely used in automobile and machine industry.
At present; the putty coating that is used for the metallic surface is to be the macromolecule resin putty coating of carrier with the organic solvent; for example unsaturated polyester or pure sour putty coating etc.; yet; generally being used for the car surface processing is to adopt rust-proofing primer; this rust-proofing primer can not stop the infiltration of oxygen, moisture content, chlorion, can not form the organic inertia protective membrane of one deck, does not therefore have the corrosion protection effect.Existing putty coating has following shortcoming:
1, weathering resistance deficiency under situations such as high temperature, UV-light, moisture content, soda acid, all can make the organic coating film embrittlement that wears out, thereby lose its sealing function;
2, adherence deficiency, the sticking power of organic putty coating and metal is mainly the physics bond, and coating seals inadequately, and with the passage of time, airborne moisture content, oxygen and chlorion infiltrate, and cause by the matel coated surface oxidisation.
The objective of the invention is to overcome the problem that prior art exists, a kind of metallic surface, strong adhesion, easy construction, nontoxic compound corrosion-proof putty coatings of organic-inorganic of being used for is provided.
The present invention is composited by inorganic materials and organic water based emulsion macromolecular compound, inorganic materials can adopt to be had rigidity, weather resistance and strong basicity thereof metallic corrosion is had inhibiting cement, and the silicon acid group that is rich in the cement etc. can form powerful chemical bond with metallic iron; Yet as a kind of coating, cement is crisp too firmly, chaps in dried excessive the causing of curing back internal stress of making an uproar; Can leave many pores after the cement solidification, the adherence of ground also is difficult for because of its hardness is too high and the ground adherence of fully fitting; Organic high molecular compound has elasticity, infiltrates the water based emulsion macromolecular material in cement, becomes semirigid elastic composite body after both are compound, and the film-forming properties of this complex body, snappiness, adherence, compactness reach the requirement that putty coating is used; Cement and organic polymer emulsion compositely proportional are in 100: 1～30: 70 the scope, and add filler, and its film-forming properties of filming, snappiness, grinability, adherence, compactness etc. all can reach the requirement of corrosion protection putty coating; Inorganic materials adopts cement, the SiO in the cement
3 2-With Fe
2+, Fe
3+Between can form chemical bonded refractory; Even, also can directly be applied to the metallic surface, and form good adhesive to rusted metal surface; The strong basicity of cement can stop corrosion of metal effectively; The compound objectionable impuritiess such as chlorion, oxygen, moisture content that prevented of fine and close inorganic and organic materials are invaded coating, thereby have solved the galvanic corrosion and the uniform corrosion problem of metal effectively; This coating is aqueous matrix, to not required by the humidity on matel coated surface, has enlarged use range; This compound putty coating price is low, and the thickness that coating can be coated with increases, and has further improved the practicality of this coating; This compound putty coating is a water-borne coatings, and is nontoxic, be convenient to construction, and it is aging to have good anticorrosion, an antifouling and ultraviolet resistance.
Advantage of the present invention is;
1, the present invention is composited by inorganic materials and organic high molecular compound, for water-based, elastic composite body, the metallic surface is had stronger sticking power, and good sealing property, anticorrosion, antifouling, long service life are arranged;
2, nontoxic, the genus water-based of the present invention, easy construction does not endanger workmen's health;
3, the present invention all belongs to initiative, and alternative traditional noxious solvent coating will be obtained bigger social benefit.
Below in conjunction with embodiment, the present invention is further described.
Embodiment 1. the present invention are composited by inorganic materials and organic high molecular compound.
Embodiment 2. the present invention constitute substantially the same manner as Example 1, and inorganic materials is a cement and the mixing of fillers such as gypsum.
Embodiment 3. the present invention constitute substantially the same manner as Example 2, and the cement of inorganic materials can adopt trass cement, rapid hardening cement, white cement etc.
Embodiment 4. the present invention constitute substantially the same manner as Example 1, organic high molecular compound can adopt and the cement uniform mixing, water-based latex polymkeric substance with certain stability comprises ACRYLIC EMULSION in the water-based latex polymkeric substance, styrene acrylic emulsion, vinyl acetate between to for plastic fat liquor, vinyl acetate vac emulsion, vinyl acetate ACRYLIC EMULSION, styrene butadiene emulsion, emulsification neoprene latex, emulsified bitumen emulsion etc.
Embodiment 5. the present invention constitute substantially the same manner as Example 1, and the compound ratio of inorganic materials and organic high molecular compound is in 100: 1～30: 70 scopes.
