Abstract
The invention provides a method for preparing aqueous anticorrosion paint, which comprises 3 to 15 weight percent of rust resisting pigment, 2 to 4 weight percent of dispersing agent, 10 to 30 weight percent of water, 0 to 1.5 weight percent of wetting agent and the balance of emulsion. The method comprises: mixing the materials, and grinding the materials to obtain pigment pulp for later use, adding a leveling agent, a film-forming aid, a thickener and a tackifier into the pigment pulp, and stirring for 10 to 45 minutes, wherein the dosages of the agents are all less than 3 percent based on the weight of the pigment pulp, the film-forming aid is suitable to be coated on a material to form a film and make the surface smooth, and the thickener can increase the attachment force of the anticorrosion paint on the material and is suitable to increase viscosity to overcome a water separation effect. Without harmful metal elements, the anticorrosion paint disclosed by the invention exceeds the standards for paint for toys for children. Meanwhile, the paint with rust can resist corrosion and prevent layering, the cost of the paint is much lower than that the conventional metal paint and the drying speed of the paint is quick.
Description
Technical field
The present invention relates to the technical field of antifouling paste or water-borne coatings, specifically is the preparation method of water-repellent preservation lacquer.
Background technology
Existing metal is with often having metal-powder in antifouling paste or the metal use coating, after pail pack leaves standstill for some time, and all the other solution generation layerings of metal-powder; In use, need normally to use after the stirring again.Bring inconvenience to use.
Existing metal is unfavorable for environmental protection with toxic substances such as often leaded in antifouling paste or the metal use coating, chromium, cadmium, aluminium, arsenic and zinc; In addition, the hardness of its coating, toughness, sticking power etc. are all relatively poor.
Chinese patent document CN101007918A discloses rust-stabilising pigment.This rust-stabilising pigment contains phytate and mica or mica system or iron mica or ferrophosphorus powder filler; The weight ratio of phytate and mica or mica system or iron mica or ferrophosphorus powder fillers is 1: 1-9 is polymerized phytate and mica or mica system or iron mica or ferrophosphorus powder filler codeposition.This rust-stabilising pigment is owing to only contain phytic acid and nontoxic filler; Toxic substances such as not leaded, chromium, cadmium, arsenic; The hardness of coating, toughness, sticking power all have significant enhancing, neither multiviscosisty, and also gel does not lump; Good with other pigment, filler and resin (water-based, oiliness) amalgamation, can allocate arbitrarily.
How utilizing above-mentioned rust-stabilising pigment to produce a kind of water-repellent preservation nontoxic, that be not prone to demixing phenomenon and coat with lacquer, is the technical barrier that this area will solve.
Summary of the invention
The technical problem that the present invention will solve provides the preparation method that a kind of step is simple, cost is lower, the water-repellent preservation of environmental protection is coated with lacquer.
In order to solve the problems of the technologies described above, the invention provides the preparation method of water-repellent preservation lacquer, comprise the steps:
A, with rust-stabilising pigment 3-15wt%, dispersion agent 2-4wt%, water 10-30wt%, wetting agent 0-1.5wt%, emulsion surplus, it is subsequent use to grind to form pigment slurry after the mixing; Simultaneously, according to required color, add corresponding environment-friendly water-based mill base.
B, in pigment slurry, add flow agent, film coalescence aid, thickening material, tackifier, stirred 10-45 minute; Wherein, the consumption of flow agent, film coalescence aid, thickening material and tackifier is respectively all less than 3% of pigment slurry weight.
Wherein, dispersion agent is used to disperse rust-stabilising pigment; The consumption of film coalescence aid is relevant with envrionment temperature, winter many usefulness, for example consumption is the 2-3% of pigment slurry weight; Summer is usefulness less, and for example consumption is below 2% of pigment slurry weight.Film coalescence aid is suitable for film forming on the material that is coated, and makes its any surface finish.
The use of thickening material is suitable for strengthening the sticking power of antifouling paste of the present invention on material, prevents that lacquer from coming off.
The use of thickening material is suitable for strengthening the viscosity of antifouling paste of the present invention, to overcome the centrifugation of water.
The preparation method of another kind of water-repellent preservation lacquer, it comprises the steps:
A, with rust-stabilising pigment 3-15wt%, dispersion agent 2-4wt%, water 10-30wt%, wetting agent 0-1.5wt%, emulsion surplus, it is subsequent use to grind to form pigment slurry after the mixing;
B, in pigment slurry, add film coalescence aid, stirred 10-45 minute; The consumption of film coalescence aid is less than 3% of pigment slurry weight.
Technique scheme of the present invention is compared prior art and is had the following advantages: the water-repellent preservation lacquer that (1) the present invention produces, owing to do not contain harmful metal ingredient, so reached toy for children with more than the coating standard.Simultaneously, can be with rust anticorrosion (can be with the rust construction); As water-repellent preservation lacquer, nontoxic, be not prone to demixing phenomenon, cost is far below existing containing metal coating, and next has rate of drying characteristics faster.Once more, the water-repellent preservation lacquer of the present invention's production has extensibility and recoverability preferably.(2) particle in the rust-stabilising pigment of the present invention's employing is thinner, and does not wrap water or water insoluble, and therefore after antifouling paste of the present invention was coated in material surface, water was volatile, has rate of drying characteristics faster.And traditional antifouling paste adopts two-pack, promptly adopts solidifying agent and solubility promoter (being generally alcohol) to accelerate rate of drying.(3) proportioning of rust-stabilising pigment and emulsion is appropriate, but is suitable for after the use forming shielding and the compactness sealing coat of air-isolation and water preferably at material surface, so be suitable for constructing at steel surface band rust.(4) the water-repellent preservation lacquer of the present invention's production; Do not contain the filler (white titanium pigment, talcum powder, lime carbonate etc.) that contains in traditional antifouling paste; And adopt the environment-friendly water-based mill base of different colours to realize covering effect preferably; Therefore low than environmental protection and cost, and the construction materials are economized, labour intensity is less, cost of labor is lower.
