Abstract
The invention belongs to technical field of coatings, be a kind of with special inorganic solvent as thinner, form by polyvinyl acetate emulsion, the polyvinyl acetal water-sol, phosphoric acid salt, red iron oxide and other conditioning agent and distilled water, compared with prior art have the following advantages: 1, nontoxic, pollution-free, do not have stink, see that fire does not burn, it is reliable to store transportation safety; 2, manufacturing process advanced person, strong adhesion, heat-resisting, water-fast, oil-proofness is good; Can be widely used in various chemical industry equipments, the antirust operation of becoming rusty of the band on all steel and iron member surfaces such as building, machinery is for China's paint production provides new product.
Description
The invention belongs to technical field of coatings, be specifically related to a kind of priming paint of heatproof.
Rust-proofing primer of the prior art, the overwhelming majority makes thinner with organic solvent, inevitably contains unpleasant odor and toxicity that organic solvent is held, sees fire burning easily, environment and laborer all there is detrimentally affect, and brush the paint film after the construction owing to contain organic solvent, and finish paint matched with it had selectivity, often cause lacquer painting wrinkling, bubble, phenomenon such as come off, grievous injury is reduced the work-ing life and the economy of product by the apparent mass of matel coated member.
The present invention overcomes outside the deficiency that prior art exists, and provide a kind of with special inorganic solvent as thinner, be with becomes rusty eliminates rust, priming paint high temperature resistant, water-fast, easy to use.
The present invention adopts following technical proposal; rust-removing and heat-resisting priming paint contains film forming raw material vinyl composition; derusting rust-proofing raw material phosphoric acid etc.; it is characterized in that thinner is an inorganic solvent; by polyvinyl acetate emulsion; the polyethylene alkyd acetal aqueous solution is as base-material; with transforming agent phosphoric acid; phosphoric acid salt; the tinting material red iron oxide; compositions such as weighting material organobentonite and other conditioning agents and distilled water, this priming paint adopts the special solvent-free thinner of doing, and dominant mechanism is to select some reactive pigment and antirust raw material for use; under the effect of mineral acid; react with active iron rust, change iron rust into new stabilized protection course one ligand compound salt deposit, securely attached to steel surface; steel surface is hedged off from the outer world, thereby directly changes deleterious iron rust layer into useful tight protective layer.Overcome existing rust-proofing primer easy firing, all drawbacks such as yielding.
The component percentages of thinner inorganic solvent of the present invention is: the film forming matter polyvinyl acetate emulsion is 25-35%, polyvinyl acetal water-sol 15-20%, red iron oxide 15-20%, organobentonite 0.5-1.2%, zinc oxide 3-5%, phosphoric acid 7-10%, phosphoric acid salt 3-5%, other regulate auxiliary agent 8-15%.The polyvinyl acetate emulsion of film forming matter vinyl, the polyvinyl acetal water-sol is made latax with suitable proportion, and its main film forming matter is a polymer, and it is strong, tough and tensile, flexible good to constitute paint film adhesion, is difficult for embrittlement, resistance to chemical attack, water-tolerant.Use film forming matter also to comprise pigment and pigment extender as base-material, zinc oxide is to have good rust-stabilising pigment, its strong covering power, and the tinctorial strength height is promoted lacquer hardness.Acidproof, alkali proof Anticorrosive Character that red iron oxide has has fast light, thermotolerance simultaneously; Rust remover phosphoric acid can form phosphoric acid salt with the ferrous iron effect, reaches the derusting action of metallic surface, makes band rusty gold metal surface constitute the phosphoric acid salt passive film, ability with basic complex, help to strengthen the water tolerance and the sticking power of paint film, form complex compound with iron simultaneously, stop the formation of iron rust.The organobentonite quality is soft, pure white, no empty shape powder, and oil number is higher, and acid, alkali are had satisfactory stability, prevents the sedimentation of pigment.The vinyl composition is simultaneously as the formation of base-material and complex compound and phosphatic formation, so film with combine together the securely passivation protection of formation one densification of alkali film thing.
Other conditioning agents of the present invention comprise talcum powder, asbestos powder, mica powder, emulsifying agent, dispersion agent etc., and talcum powder is a kind of hydroxo complex, can improve paint film adhesion, improve the brushing property of lacquer and prevent to coat with lacquer in the heavy collection of pigment.Talcous structure forms the particle featheriness, helps to strengthen the physical strength of paint film.
Asbestos powder is that cotton pulverizing of a kind of calcium carbide made, and oil number is big, and all very high to the stability of acid, alkali, heat, heat transfer coefficient is little, has heat-blocking action.
Mica powder is a kind of tenderly white pearl shred, can stop ultraviolet ray and moisture penetration, prevents be full of cracks, and chalk retardation can strengthen weather resistance, weathering resistance and the water-repellancy of paint film.
They can promote the emulsification of base-material emulsifying agent and dispersion agent, and homodisperse pigment and pigment extender stop the flocculation of material in thinner, guarantee the stability of paint vehicle, prevent the gathering of paint vehicle discrete particles in storage.
Distilled water: in water-soluble vehicle, play the dispersion effect, simultaneously some material is played hydrolytic action.
Other regulate auxiliary agent can be according to the requirement preparation effect of technology and workpiece.
Main technical details of the present invention is:
1, outward appearance: reddish-brown, smooth smooth.
2, viscosity: (coating-4 viscosity meter) is not less than 20(S).
3, coating shock strength: 〉=50(Kg-CM).
4, coating adhesion: (cross-hatching) 100%.
5, surface drying time: 4 hours.
6, do solid work the time: 24 hours.
7, resistance to salt water: (be dipped in 3% salt solution 72 hours) paint film do not come off, non-foaming.
8, temperature-change resistance: (20 ℃ 30 minutes ,+50 ℃, 30 minutes, circulate four times) paint film does not ftracture, and does not come off, projection not.
9, oil-proofness: (be dipped in 25 ± 1 ℃, the CHSY1502-77 big gun with in the lubricating grease 24 hours) paint film is non-foaming, do not come off.
10, nitrocellulose lacquer resistance: non-foaming, do not expand, nonbleeding.
11, thermotolerance: 100-150 ℃.

2, by the various material order of addition(of ingredients) of technical recipe requirement regulation, reinforced in paste mixer, generally add base-material (film forming matter) polyvinyl acetate emulsion earlier, the polyvinyl acetal water-sol and part distilled water carry out normal temperature (18-35 ℃) and stir, and make it even.Then add powder by proportioning per-cent: zinc oxide, red iron oxide, medium chrome yellow medium yellow, zinc phosphate, talcum powder, organobentonite etc., and proceed to stir and reach evenly.
3, carry out homogeneous in the immigration shredder and grind, after mesh-of-grind reaches 40-80 μ, think qualified.
4, move in the color matching system, start stirring, add auxiliary agent simultaneously, the OP-10 emulsion is with reaction solution tbp and phosphoric acid, till stirring at normal temperatures.
5, filter, remove foreign material, by the pail pack of quantitatively packing into, then by the standard sampling inspection.
The present invention compared with prior art has element, pollution-free, odorless, sees that fire does not burn, and it is safe and reliable to store transportation; Manufacturing process advanced person, strong adhesion, heat resistance, resistance to water, oil resistivity, temperature tolerance, the advantage such as corrosion resistance is strong, can be widely used in underground piping, the antirust operation of becoming rusty of the band on all steel component surfaces such as boats and ships, vehicle, iron tower, bridge, boiler, chemical industry equipment and all kinds of machinery, building. For China's paint production provides new product.
