Water glass iron oxide red priming paint and preparation method thereof

Abstract

The invention discloses a water glass iron oxide red priming paint and a preparation method thereof. The water glass iron oxide red priming paint is prepared by compatibility of the following material components according to the weight: 80-100 of water glass, 1.5-3 of a wetting agent, 2-5 of zinc oxide, 2-5 of zinc phosphate, 3-5 of precipitated barium sulfate, 10-15 of an iron oxide red pigment, 2-5 of a talc powder, and 1-3 of a dispersible latex powder. The preparation method comprises the steps: mixing water glass and the wetting agent according to the above-mentioned proportion, and then adding and mixing the other materials according to the weight; after stirring the above raw materials evenly, putting into a ball mill, firstly adding water and 1 part of a waterproof glue into a pot, slowly adding the ground slurry into the pot, successively adding 2 parts of a flake zinc powder, 0.2 part of a defoaming agent and 2 parts of a lustre-enhancing agent (liquid wax); and finally, adding 5 parts of water in the ball mill to obtain the finished product. The water glass iron oxide red priming paint has the advantages of corrosion prevention, rust protection, high-temperature resistance, strong adhesion force, acid resistance and water resistance, has the hardness which can reach 5 H, and has quite good corrosion prevention effect on steel in water.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water glass iron red primer using water glass as a main raw material and a preparation method thereof. Background technique [0002] Paints and coatings are the last base material required for coating of buildings and various objects. After chemical paints and coatings are applied, they will continuously volatilize organic compounds (VOC) and free bodies (TDI). It not only produces ozone pollution to nature, but also causes discomfort symptoms such as headaches and general paralysis; however, lead, an organic compound, is one of the main culprits, and the chemical paints currently used are difficult to meet this standard. Contents of the invention [0003] The object of the invention is to overcome the deficiencies in the prior art, and provide a kind of not only can eliminate the volatilization of organic compound, the green environmental protection water glass iron red...
