Abstract
The invention discloses a water-borne non-toxic coating. A preparation method of the water-borne non-toxic coating includes the steps of firstly, mixing, by weight percentage, 40% of modified acrylic emulsion, 25% of titanium dioxide, 0.5% of aqueous rheological agent, 1% of aqueous dispersant and 33.5% of distilled water; secondly, mixing water-borne curing agent with the mixture obtained in the first step in an equal-weight manner, stirring at the high speed of 3000-4000r/min for 30 minutes, and curing at normal temperature for 3-5 minutes; thirdly, using a grinder to grind cured substances in a disperse manner to obtain the non-toxic coating, wherein the fineness is 15-20 micrometers. The preparation method has the advantages that the water is used as diluent, environment pollution can be avoided, all components of the coating are non-toxic, and the prepared water-borne non-toxic coating is high in water resistance, alkali resistance and dirt resistance, quite easy to clean and extremely good in adhesive force.
Description
Technical field
The invention belongs to technical field of coatings, be specifically related to a kind of aqueous non-toxic coating and preparation method thereof.
Background technology
In the modern life there is the loose dirt settlings such as welding slag, iron rust, water mark, greasy dirt, dust in increasing drinking equipment; therefore one deck chemistry painting industry need be smeared at drinking equipment ectonexine; but traditional drinking equipment coating contains organic solvent volatile matter; it is faster that the volatile matter that is heated volatilizees; thus serious pollution is caused to environment; even health of people is impacted; along with people's improving constantly environmental protection requirement; traditional coating can not meet the demand of people; be eliminated gradually, people are badly in need of a kind of environmentally friendly non-toxic coatings.
Summary of the invention
The present invention is directed to above-mentioned weak point and a kind of aqueous non-toxic coating provided and preparation method thereof, this preparation method is using water as thinner, can not pollute environment, it is all nontoxic for preparing coating composition used, the aqueous non-toxic coating prepared has excellent water tolerance, alkali resistance, the easy clean property of anti-soil, and sticking power is splendid.
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is:
A preparation method for aqueous non-toxic coating, comprises the following steps:
(1) following ingredients is mixed by weight percentage: modified acrylic acid emulsion 40%, titanium dioxide 25%, water-based auxiliary rheological agents 0.5%, aqueous dispersant 1%, distilled water 33.5%;
(2) mixed with weight such as step (1) gained mixtures by waterborne curing agent, high-speed stirring 30min, stirring velocity is 3000 ~ 4000r/min, then normal temperature slaking 3 ~ 5min;
(3) by the sand mill dispersion grinding of the material after slaking, fineness is 15 ~ 20um, obtains non-toxic coatings.
Further, the water-based auxiliary rheological agents described in step (1) is polyurethane associative thickener.
Further, the aqueous dispersant described in step (1) is nonionic polyurethane dispersion agent.
Further, the waterborne curing agent described in step (2) is aqueous amine epoxy hardener.
According to the aqueous non-toxic coating that above-mentioned preparation method prepares.
A kind of aqueous non-toxic coating provided by the invention and preparation method thereof, has following several beneficial effect:
(1) this preparation method is using water as thinner, can not pollute environment, prepare coating composition used not containing alkylphenol polyvinyl ether, VOC and tin compound, all nontoxic, the aqueous non-toxic coating odorlessness prepared, have excellent water tolerance, alkali resistance, the easy clean property of anti-soil, sticking power is splendid.
(2) preparation process is simple, and according to lotus-effect, the hydrophobic surface of low film coated surface and high contact angle forms enrichment nano-scale and gives prominence to structure, can remove coated article surface blot easily.
(3) can be used for water supply pipe and metal drinking water equipment inside and outside coating, also can be used for food factory, pharmaceutical factory's anticorrosive coating, the loose dirt settlings such as the welding slag on coated article surface, iron rust, water mark, greasy dirt, dust can be processed, make it surface clean, drying, smooth.
