Description
Technical Field
The invention belongs to the technical field of corrosion prevention and rust prevention, and relates to a water-based rust-proof primer and a preparation method thereof.
Background
The metal corrosion is ubiquitous and is particularly prominent in the harsh marine environment, thereby causing great economic loss and potential safety hazard. The best solution to this problem of metal corrosion in the prior art is to apply an anti-corrosive, anti-rust primer sealer. The seal coat is mainly used for preventing moisture and resisting alkali isolation, and can effectively isolate alkali of the base layer and prevent the alkali from seeping to damage the coating. The sealing primer has two types of solvent and water, so that the emission limit standard of Volatile Organic Compounds (VOC) is established all over the country at present, and the development of environment-friendly coatings such as non-solvent type coatings, water-based paints and the like is encouraged to bring opportunities.
The water-based seal primer mainly uses water as a solvent, is a non-toxic, tasteless, non-flammable, non-explosive and non-pollution environment-friendly product, and has the working mechanism that active rust forms a stable and compact heteropoly acid complex under the action of inorganic salt through certain active pigments and antirust pigments, so that the rust is passivated and inactivated, and an antirust protective layer is obtained.
However, although the existing water-based seal primer is superior to the traditional paint in environmental protection performance, the water-based paint product has the defects of difficult construction, water resistance, easy peeling, poor fullness, poor hardness, high water content of the coating, more obvious damage of ultraviolet rays to a base material and the like in physical performance. We have therefore proposed a water-based rust inhibitive primer and a method for preparing the same so as to solve the problems set forth above.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a water-based antirust primer and a preparation method thereof.
In order to achieve the object of the present invention, in one aspect, the present invention provides a water-based anti-rust primer, which comprises, by weight:
30-45 parts of aqueous polyvinylidene chloride resin;
5-10 parts of iron oxide red;
5-15 parts of talcum powder;
3-8 parts of mica;
5-10 parts of composite antirust pigment;
0.1-3 parts of dodecyl alcohol ester;
0.1-3 parts of a surfactant;
0.1-3 parts of a water-based wetting agent;
0.1-3 parts of a dispersant;
0.1-3 parts of water-based thickening rheological agent;
0.1-3 parts of water-based matting powder;
0.1-3 parts of a defoaming agent;
bacteriostatic agent 2- (3-methyl cyclopropyl) benzo [ d ] isothiazole-3 (2H) -ketone 0.1-3 parts;
0.1-4 parts of preservative;
and an appropriate amount of deionized water.
In some preferred embodiments, the aqueous polyvinylidene chloride resin of the present invention is a terpolymer of VC (vinyl chloride)/VDC (vinylidene chloride)/MMA (acrylic acid) which is aqueous, and has a weight-average molecular weight of 75000 to 90000, preferably a product available from megaterium limited.
