Abstract
The present invention provides water iron black primer and a preparing method thereof. The water iron black primer is characterized in that chloride emulsion is used as the film forming substance of the primer, and self-made rosin resin emulsion with an internal phase in a liquid state is added to be prepared into composite emulsion. Tributyl phosphate is used as a defoaming agent and mutually acts with sodium tripolyphosphate as the chemical rust inhibitor of the primer. The present invention has less foam and is suitable for being dipped. Pigment can not be easily precipitated and caked. The water iron black primer has the advantages of strong light resistance, strong rust prevention, safe use, simple technology and low production cost and is an ideal product for replacing solvent paint.
Description
The present invention relates to the emulsion paint technical field.
In the last few years, because of the reinforcement big and environmental regulation of the prices of raw and semifnished materials rising range of conventional solvent type lacquer has increased the investment that manufacturer handles useless by product, and the growth of the anti-solvent contamination mood of people, the reinforcement of economize on resources, save energy being realized has promoted world's coatings industry hydrotropismsization development., more considerable part is arranged, thereby have more DEVELOPMENT PROSPECT at aspects such as technical indicator, use properties, environment protection as water emulsion type rust-proofing primer.Two piece Europe patent documentation EP0313314 and the EP0264655 the most approaching that now retrieve with the present invention, its technology contents relates generally to the following aspects:
1, with vinylidene chloride as principal monomer, with vinyl acetate between to for plastic, acrylate, vinylchlorid or other monomer copolymerizations, make latex different on the performance respectively;
2, influence the performance of latex with nonionogenic tenside, anion surfactant;
3, improve the preparation technology of latex, make it to obtain the little emulsion of latex granularity as far as possible;
4, utilize the rustless property of the sequestering action raising rust-inhibiting paint of Weibull.
The weak point of above-mentioned water based emulsion rust-inhibiting paint is: the pigment precipitation of easily luming; Foam is many and be difficult to elimination, is unsuitable for dip-coating; Photostabilization is poor.
The purpose of this invention is to provide a kind of foam few, be suitable for dip-coating, pigment and be difficult for strong water-thinned iron-black primer aand of precipitation caking and photostabilization and preparation method thereof.
The feature of this water-thinned iron-black primer aand is to contain by its weight percent meter: vinylchlorid-vinylidene chloride copolymer emulsion (being called for short chlorine-meta-latex emulsion) 18.84～32.68, Gum Rosin 7.56～17.13, varsol 4.07～25.69, dioctyl phthalate (DOP) 0.81～1.71, non-from type emulsifying agent 0.3～3.81, ethylene glycol 0～0.07, sodium polymethacrylate 0～0.01, iron oxide black 10.95～20.16, carbon black 0～3.62, talcum powder 0～13.43, tripoly phosphate sodium STPP 0.08～0.17, tributyl phosphate 0.15～1.96, surplus are water.
Above-mentioned Gum Rosin is meant maleficent acid modified rosin glycerol resin, or maleficent acid modified rosin pentaerythritol resin, or rosin glycerol resin, or the rosin pentaerythritol resin; Varsol refers to rosin or 200# solvent oil; Nonionic emulsifier refers to the miscellany of OP-10 or OP-10 and OS-15, and the percentage composition of OS among the latter-15 is 0～0.49.Wherein OP-10 is alkylphenol and ethylene oxide condensate; OS-15 is Fatty Alcohol(C12-C14 and C12-C18) and ethylene oxide condensate.
The making method of this water-thinned iron-black primer aand is at ambient temperature:
A, dissolving: get 0.4～0.7 part of dioctyl phthalate (DOP) and mix, add 4～6.5 parts of Gum Rosins under the condition of trembling stirring, make Gum Rosin solution with 3.5～6 parts of varsols; (its amount of getting is descended together all by weight)
B, preparation foreign minister material: get 8.5～10 parts of water, 1.3～1.85 parts of nonionic emulsifier, 0～0.2 part of ethylene glycol and 0～0.02 part of sodium polymethacrylate and mix, make foreign minister's material;
C, emulsification: rotating speed greater than 1500 rev/mins emulsifying device in, with 2.9～3.5 parts of above-mentioned Gum Rosin solution slowly join 1 especially mutually the material in, make the Gum Rosin emulsion;
D, preparation mill base: tripoly phosphate sodium STPP is soluble in water and add 1 part of iron oxide black, 0～0.25 part of carbon black and 0～1 part of talcum powder, grind the mill base of making its granularity≤50 μ; The weight of the tripoly phosphate sodium STPP that adds accounts for 0.4～0.6% of iron oxide black and talcum powder gross weight, and the weight of water accounts for 25～45% of mill base gross weight;
E, join lacquer: get 1 part of vinylchlorid-vinylidene chloride copolymer emulsion and mix with 0.5～3 part of above-mentioned Gum Rosin emulsion, and add 1～3 part of mill base, and mix, add the tributyl phosphate that its weight accounts for total lacquer amount 0.15～1.96% again, mix, be mixed with water-thinned iron-black primer aand.
In the aforesaid method, the Gum Rosin that adds in the dissolution process is a maleficent acid modified rosin glycerol resin, or maleficent acid modified rosin pentaerythritol resin, or rosin glycerol resin, or the rosin pentaerythritol resin; Said varsol be rosin or 200# solvent by; Used nonionic emulsifier is the miscellany of OP-10 or OP-10 and OS-15 when the preparation foreign minister expects, the weight percentage of OS among the latter-15 is 0～0.49; When the preparation mill base, can add the OP-10 that its weight accounts for mill base gross weight 0～6%.
The present invention is (to be vinylchlorid-vinylidene chloride copolymer emulsion at chlorine-meta-latex emulsion, down with) in added and be made into composite emulsion for liquid state and Gum Rosin emulsion with volatile dry performance mutually in homemade, the Gum Rosin emulsion that is added is the stiff pulpous state, viscosity reaches more than 7000 centipoises, thereby has strengthened the viscosity of chlorine-meta-latex emulsion; This Gum Rosin emulsion also has good froth breaking effect, cooperatively interacts with tributyl phosphate, has solved the many problems of chlorine-meta-latex emulsion foam; The good dispersing property that this Gum Rosin emulsion is had, the pigment that has solved aqueous priming paint effectively easily precipitates the problem of caking, and has improved pigmenting power and opacifying power; Above-mentioned Gum Rosin emulsion also has good photostabilization, and iron oxide black and sooty use except that increasing tinting strength, blackness, opacifying power, also have anti-ultraviolet property, and the combination of the two has strengthened the photostabilization of chlorine-meta-latex emulsion; The composite emulsion that chlorine-meta-latex emulsion and Gum Rosin emulsion form is in the volatile dry process, the Gum Rosin emulsion particle can be filled up the space between the chlorine one inclined to one side emulsion particle, after the common film forming, improved the closure of paint film, the tributyl phosphate that adds is except that having the froth breaking effect, after the pentasodium triphosphate of dispersing agent acting in conjunction, also have good rust inhibition, thereby strengthened the rustless property of this aqueous priming paint.In addition, this aqueous priming paint the gathering that attracts each other, also exists the volatile dry film process of Gum Rosin particulate simultaneously between emulsion particle in the volatile dry process, thereby make its characteristics, be convenient to various application processes such as spraying, brushing, dip-coating with some solvent-thinned paints.
In sum, but major advantage reduction of the present invention is as follows:
1, foam is few, is applicable to spray, brushes, soaks and other various application processes;
2, pigmenting power and strong covering power are difficult for the precipitation caking;
3, fast light and rustless property is strong;
4, fast drying, short construction period, save energy;
5, the prices of raw and semifnished materials are cheap, and technology is simple, and production cost is low;
6, available tap water dilution is not fired not quick-fried, safe in utilization;
7, overall target meets or exceeds alcohol acid primer, is the ideal product that replaces solvent bottom paint;
8, regulate proportioning, can make the aqueous priming paint of different performance characteristics, to meet the different needs.
Below enumerate optimum implementation of the present invention.
