Abstract
The invention discloses a waterborne zinc-enriched paint and a preparation method thereof. The preparation method comprises the following steps: pouring a certain amount of a sodium silicate solution into a vessel, heating, continuously stirring while dropwise adding silica sol to mix the sodium silicate solution with silica sol, adding a certain amount of a silane coupling agent, stirring at a high speed, stopping heating, adding a silicone acrylic emulsion after the temperature is lowered to room temperature, and finally adding an appropriate amount of superfine zinc powder, continuously stirring for a certain time to obtain the waterborne zinc-enriched paint. The waterborne zinc-enriched paint is low in price, low in cost, energy-saving, environment-friendly and convenient to process.
Description
Technical field
The present invention relates to a kind of paint, particularly rich zinc aqueous paint of one and preparation method thereof, belongs to paint chemical field.
Background technology
Metallic corrosion be people face very seriously and problem the most general, the whole world accounts for the 2%-4% of various countries GDP every year because corroding the financial loss caused, the metal scrapped because of corrosion reaches more than hundred million tons.The corrosion of metal is modal etch state.During corrosion, the interface of metal there occurs chemistry or electrochemistry heterogeneous reaction, metal is made to proceed to oxidation (ion) state, this significantly can reduce the mechanical property such as intensity, plasticity, toughness of metallic substance, destroy the geometrical shape of hardware, increase the wearing and tearing between part, worsen the physicals such as electricity and optics, in the work-ing life of shortening equipment, even cause the catastrophic failure such as fire, blast.
Steel corrosion is as modal a kind of metallic corrosion, and according to statistics, the iron and steel of the direct loss due to corrosion every year, accounts for 1/4th of iron and steel annual production.People delay the corrosion speed of iron and steel by various mode, as improved base material, selecting anticorrosive, increase metal plating, add inhibiter, adopting electro-chemical protection.People, by adding other materials to suppress in pure metal or stoping corrosion of metal, achieve success in various degree.But the micro substance added in iron may accelerate the speed of corroding, and the shortcoming adopting the material being less likely to occur to corrode to solve etching problem is and original metallographic phase ratio, its physicals often lacks to some extent, or causes cost to increase due to the cost of alloy.Therefore the most frequently used anti-corrosion mode is exactly to needing the additional top coat (or coating) having a tolerance of the metal of protection.The material that this type coating uses is different, but conventional be paint.General anticorrosion coating is on the one hand containing a large amount of organic solvent, and solvent based coating, in production and construction stage, has a large amount of solvents and is discharged in air, not only endanger the healthy of workmen, and cause environmental pollution.On the other hand, common paint is just simple covers isolated air, and preservative activity is not strong.
The present invention, by a kind of waterborne zinc-rich paint of development, is coated in steel surface, thus greatly extends the work-ing life of steel construction.This paint adopts high-module silicate to be base-material; by silicate and zinc powder cross-linking reaction film forming under certain condition; due to the standard potential of zinc, comparatively iron and steel is low; when corrosive medium infiltrates; iron and steel and zinc powder form galvanic cell; zinc powder loses electronics as the negative pole of galvanic cell, and iron and steel obtains electronics as positive pole and obtains protection.In addition, the anion binding in the zine ion be dissolved out and corrosive medium and form basic zinc salt and zinc-iron double salt, fills up the crack of film, and reaches the etch-proof object of isolation.And owing to being aqueous paint, avoiding organic solvent to endanger the health of workmen, there is environmental-protection function.
Summary of the invention
The object of this invention is to provide a kind of waterborne zinc-rich paint and preparation method thereof.
For realizing this purpose, this paint comprises the raw material of following mass fraction:
Water glass 3%-5%;
Silicon sol 20%-50%;
Silane coupling agent 7%-10%;
Organosilicon crylic acid latex 20%-30%;
Super-fine zinc dust 20%-30%;
A kind of preparation technology of waterborne zinc-rich paint comprises the steps:
(1) pour a certain amount of sodium silicate solution into vessel in heating, temperature controls at 30-70 DEG C;
(2), under ceaselessly stirring, slowly drip the silicon sol of metering, make it fully mix;
(4) in container, add the silane coupling agent of certain metering again, high-speed stirring;
(4) stop heating, when temperature is down to room temperature, add organosilicon crylic acid latex;
(5) finally add appropriate super-fine zinc dust, Keep agitation 10-15 minute a kind of waterborne zinc-rich paint.
The present invention has following advantages and characteristic:
(1) water glass is cheap, material is easy to get, cost is low;
(2) the less demanding and energy-saving and environmental protection of this preparation technology;
(3) the paint good mechanical property prepared, easy construction.
