Abstract
A kind of antirust coatings, it is by the rust-eliminating and rust-preventing agent, membrane-forming agent, solvent and subsidiary material are formed, and it is characterized in that prescription is constructed as follows (weight percent): epoxy is resin and polyvinyl acetal 15～20; Phosphoric acid and Weibull 2～3; Phosphoric acid salt and lead salt 10～15, all the other are ferriferous oxide, talcum powder and organic solvent.The advantage that this coating collection has transformant, stable form, osmosis type Rust-resisting coating now is an one, can not only adapt to the construction of various band rust workpiece, and coating drying property, humidity resistance, erosion resistance and coating adhesive power have been significantly improved, except that having strengthened the rust-eliminating and rust-preventing function, strengthened the workpiece metal surface strength.
Description
The present invention relates to a kind of rust proof paint.
Rust proof paint in the past, need base material thoroughly eliminated rust with preceding elder generation, not only bother but also require great effort, Rust-resisting coating has been arranged now, as rust-converter coating, stable form on rust paint and osmosis type on rust paint, though overcome the defective of the coating of the preceding rust cleaning of rust proof paint need worker in the past, but be mostly based on a kind of action principle, function singleness, adaptability is restricted; In these existing Rust-resisting coatings, often owing to reactive pigment in its component is more, to making coating do solid work the back at the application floating coat floating, efflorescence appears particularly, poor adhesion, and quality is loose; Some compound has the dried effect of resistance in the component in addition, directly influences the drying property and the moisture-proof thermotolerance of coating; In addition, present Rust-resisting coating, the need that have divide packing pigment, and the time spent cooperates; The anti-time solidity to corrosion that has is poor, in heat, cold environment construction inconvenience; The need that have add solidifying agent in paint vehicle.
The purpose of this invention is to provide a kind of perviousness strong, transform fully and stablize good antirust coatings, the paint film good toughness, strong adhesion, drying property and moisture-proof heat, resistance to chemical corrosion are good, the coating individual packaging must not add solidifying agent more in addition.
The object of the present invention is achieved like this, and it is made through grinding by the prescription mixing by rust-eliminating and rust-preventing agent, membrane-forming agent, organic solvent and subsidiary material again, it is characterized in that prescription of the present invention following (weight percent):
Epoxy is resin and polyvinyl alcohol acetal 15～20
Phosphoric acid and Weibull 2～3
Phosphoric acid salt and lead salt 10～15
All the other are ferriferous oxide, talcum powder and organic solvent.
In this prescription, epoxy is the most handy 634 Resins, epoxy of resin, and it preferably accounts for 7～10% of gross weight; The most handy plumbic acetate of lead salt and lead silico-chromate, they account for 1～2% and 5～8% of gross weight respectively is good; Phosphoric acid salt is generally used zinc phosphate, and ethanol and butanols are arranged in the organic solvent.
Lead silico-chromate is a kind of orange antirust core pigment, and its core is silicon-dioxide (SiO
2), its skin is a kind of active alkali formula lead salt cladding, this cladding comprises γ-ternary lead silicate white (PbSiO
33PbO) with monobasic basic lead chromate (PbCrO
4PbO), contain certain density silicic acid in lead silicate solution, be the colloidal solution state and exist, the phosphoric acid in the coating composition can make silicic acid split out and react with iron, zinc:
Perhaps FeSiO
3ZnSiO
3The double salt of form;
PbSiO
3SiO
2Can generate insoluble double salt with metal oxide (ZnO and PbO):
So just strengthened filming from solidity, but the coating individual packaging need not add other solidifying agent, and PbSiO
3Can constantly absorb airborne CO
2Thereby, can progressively finish solidification process:
By above-mentioned reaction, this type silicate coating of consolidating certainly is actually a kind of half inorganic tackiness agent, has further improved adhesive force of coatings, has strengthened the toughness of paint film.Though lead silico-chromate belongs to plumbous compound, but its structure uniqueness, it is that form with sour insoluble compound lead chromate and lead silicate exists that 1/2 lead is arranged in its chemical ingredients, is deleterious so only account for the alkaline PbO of pigment weight 1/4, therefore with traditional rust-stabilising pigment ratio, its toxicity reduces greatly.Because the upper layer of this granules of pigments is the antirust component that progressively hydrolysis plays corrosion inhibition, and solubleness is low, validity period is long, and its nuclear is SiO simultaneously
2, so tinting strength is very low, weathering resistance and closure are fine, are called " concentration protection " system, have improved rust-proof effect.It not only has the stabilization of leadization thing, and there is the resistance of chromic salt to lose performance, the effect of corrosion inhibition is good, its rustless property is considerably beyond traditional rust-stabilising pigment, it is good to the adaptability of various coating, and versatility is widely arranged, almost can in solvent-borne type and water-borne coatings, all can use with all resins (paint vehicle combination).
The adding of plumbic acetate (PbAC) has in fact risen resin and has urged dried solidification, and the epoxy group(ing) in the resin has not only been sealed in hydroxyl in it and epoxy system and the polyvinyl alcohol acetal-based resin and carboxyl, epoxy group(ing) effect
Make resin both have the characteristic of organic resin simultaneously, the characteristic that has metal element again, make coating have good thermotolerance, water tolerance, chemical proofing has strengthened the coating dryness, preservative property and stability in storage, having improved strength of coating PbAC urging of resin done curing, be not only the oxypolymerization of resin double center chain, also is the crosslinked of PbAC oxygen key and epoxy group(ing) simultaneously, because of its cross-linking density big, so this coating is fine and close more behind some months, its intensity also significantly improves (we claim that it is " petrochemical industry " this phenomenon), simultaneously the also corresponding execution of coating performance of having improved, as the thick not sagging that is coated with, do not produce pin hole etc.In addition, the ionization of PbAC generates Pb
++, the butanols reaction in it and the coating composition:
Pb(OC
4H
9)
2Stopping reaction:
Its reactant has goodish sticking power and intensity.
The present invention compared with prior art, adopting epoxy is that resin is made film-forming components, introduce plumbic acetate and lead silico-chromate, rational proportion by each component, improved the rust-eliminating and rust-preventing function of coating, and strengthened the physicals such as adhesive power, surface strength and anticorrosion with coat, drying, heat resistance of paint film, thereby improved the execution of coating performance, strengthened application adaptability.
