Abstract
The present invention relates to corrosion resistance paint and a preparing method thereof. The corrosion resistance paint contains chloroethene-metachloroethene copolymerized emulsion, pigment slurry and digallic acid-resin emulsion, wherein the pigment slurry is prepared from sodium tripolyphosphate, talc powder, bentone, pigment and water; the digallic acid-resin emulsion is prepared from the solvent oil of No. 200, xylene, rosin resin, dioctylphthalate, non-ionic emulsifier, water and digallic acid. A water-soluble acrylic thickening agent is used for regulating viscosity, and a non-silicon polyether-type defoamer is used for defoaming. Aquosity anti-corrosive primer has the advantages of low cost, stable performance, no environmental pollution and no combustion and can replace oiliness anti-corrosive primer.
Description
The present invention relates to a kind of anti-corrosive paints and preparation method thereof.
Traditional oiliness rust-proofing primer, not only can contaminate environment, and because its inflammable characteristic, measures for the prevention of fire to painting hall, strict, perfect fire-protection device is arranged, therefore development is not burnt, water-thinned antirust primer free from environmental pollution replaces the oiliness rust-proofing primer imperative, be that water-thinned iron-red primer of 92106610 and preparation method thereof is water-thinned iron-black primer aand of 92106612 and preparation method thereof with the patent No. as the patent No., disclosing and utilized vinylchlorid---the copolymer emulsion of vinylidene chloride is as the filmogen of priming paint, adding in homemade is liquid mutually, contain Gum Rosin, varsol, nonionic emulsifier, dioctyl phthalate (DOP), pigment, the Gum Rosin emulsion preparation composite emulsion of compositions such as talcum powder, adopt tributyl phosphate as defoamer and with the tripoly phosphate sodium STPP acting in conjunction, become the physical property rust-preventive agent of priming paint.Though above-mentioned two patents can be produced water-thinned antirust primer, have following deficiency: 1, lack emulsion cross-linking agent and inner complex owing in the emulsion, thereby make the unstable properties of product, rust-proof effect is bad; Though 2, the slightly acidic tributyl phosphate is the defoamer of recommending in each relevant professional books, is used for this water-thinned antirust primer, not only defoaming effect is bad, and a large amount of acid groups is brought in the lacquer liquid, directly influences the quality of product and the stability of product; 3, vinylchlorid---vinylidene chloride copolymer emulsion and the Gum Rosin emulsion content height in the prescription makes the cost of product very high, is the twice of common oiliness rust-proofing primer.Because above-mentioned deficiency causes No. 92106610 and No. 92,106,612 two patents can't be produced the water-thinned antirust primer that price is low, performance stably reaches customer requirements again.
The objective of the invention is to propose that a kind of cost is low, stable performance, can substitute water-thinned antirust primer of oiliness rust-proofing primer and preparation method thereof.
This water-thinned antirust primer comprises vinylchlorid---vinylidene chloride copolymer emulsion, Gum Rosin, nonionic emulsifier, No. 200 solvent oils, dimethylbenzene, dioctyl phthalate (DOP), tripoly phosphate sodium STPP, water soluble propene's acid type thickening material, talcum powder, pigment, water, wilkinite, tannic acid and non-silicon series polyether type defoamers, its content is by weight percentage

Water surplus,
In the above-mentioned prescription, Gum Rosin is selected Gum Rosin for use No. 424, and nonionic emulsifier is selected O π type or OS type for use, and pigment comprises that red iron oxide, iron oxide black add carbon black or iron oxide yellow adds antirust Huang.
The making method of this water-thinned antirust primer comprises the steps:
A, get material
A, at first choose raw material by proportioning;
B, be four parts with selected moisture again, first part of water accounts for the 10-15% of Total Water, and second part of water accounts for the 35-45% of Total Water, and the 3rd part of water accounts for the 10-15% of Total Water, and surplus is the 4th a part of water;
B, system mill base
A, tripoly phosphate sodium STPP is dissolved in first part of water, makes the tripolyphosphate sodium water solution;
B, talcum powder, wilkinite, pigment and second part of water are joined in the above-mentioned aqueous solution, grind to form the pasty state of granularity≤60um again, make mill base;
C, system emulsion
A, No. 200 solvent oils and dimethylbenzene are mixed, as solvent;
B, under agitation condition, in above-mentioned solvent, slowly add the Gum Rosin fragment, directly cause fragment all after the dissolving, add dioctyl phthalate (DOP) again, continue to stir, mix, make Gum Rosin solution;
C, Gum Rosin solution, nonionic emulsifier and the 3rd part of water are put into emulsifying device, under 26 °-48 ℃ of temperature and high speed rotating condition, make its emulsification, form emulsion;
D, under agitation condition, in above-mentioned emulsion, add tannic acid, tannic acid is dispersed in the emulsion, form tannic acid---resin emulsion;
D, synthesized primer
Under agitation condition,---resin emulsion, vinylchlorid---vinylidene chloride copolymer emulsion and the 4th part of water uniform mixing with mill base, tannic acid, add water soluble propene's acid type thickening material and non-silicon series polyether type defoamer again, stir, promptly get water-thinned antirust primer after filtering.
Characteristics of the present invention are to contain wilkinite, tannic acid, non-silicon series polyether type defoamer and water soluble propene's acid type thickening material in prescription, and are to add in three different operations of making water-thinned antirust primer.Add wilkinite when the system mill base, it is a kind of inner complex, plays thickening, anti-heavy, stable lacquer liquid system; When the system emulsion, add the rush-resisting material tannic acid, and make tannic acid be the stable dispersion state to appear in the emulsion, it can stop the vinylchlorid in the water-thinned antirust primer effectively---the same iron ion action of vinylidene chloride copolymer emulsion, and whole lacquer liquid system is neither condensed, very stable again; In the synthesized primer operation, add water soluble propene's acid type thickening material and non-silicon series polyether type defoamer, water soluble propene's acid type thickening material plays thickening, crosslinked action, make the latex particle in the water-thinned antirust primer form reticulated structure, and adsorption pigment particle, make the lacquer liquid system stable, not stratified, do not sink to the bottom, increase staging life, thickening effectiveness is obvious, the viscosity setting range is big, is applicable to the different denseness requirements of various enamelling processes fully, can also improve the glossiness and the fine and closely woven degree of paint film, and then raising antirust function,---vinylidene chloride copolymer emulsion and tannic acid---content of resin emulsion that thereby can reduce vinylchlorid in the water-thinned antirust primer reduces cost of manufacture significantly, makes non-environmental-pollution, incombustible water-thinned antirust primer is replaced contaminate environment, the imagination of incendive oiliness rust-proofing primer comes true; Non-silicon series polyether type defoamer is a kind of defoamer that is applicable to viscous fluid, and defoaming effect is obvious, the influence of acid and alkali alkali.
