Black water glass high-temperature paint and preparation method thereof

Abstract

The invention discloses a black water glass high-temperature paint and a preparation method thereof, and is characterized in that the paint is prepared by compatibility of the following raw material components by weight: 80-100 of water glass, 1.5-3 of glycerol, 2-5 of zinc oxide, 2-5 of zinc phosphate, 10-15 of a magnet powder, 4-6 of a glass powder, and 1-3 of a dispersible latex powder. The preparation method comprises the following order and steps: firstly, mixing the raw materials according to the proportion, and stirring evenly; secondly, transporting the paint slurry to the interior of a ball grinding mill by a filling machine, grinding for 30-60 minutes; thirdly, adding 5 parts of water and 1 part of a waterproof glue into a pot, slowly adding the ground slurry into the pot, successively adding 0.2 part of a defoaming agent and 2 parts of a lustre-enhancing agent (liquid wax), and thus obtaining the finished product. The 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 paints and coatings, in particular to a black water glass high-temperature paint 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 purpose of the present invention is to overcome the deficiencies of the prior art, and provide a green, environmentally friendly, high-temperature resistant, fire-resistant, safe, low-cost, ...
