Water soluble inorganic silicon solution rust-inhibiting primer and preparation method thereof

Abstract

The invention relates to rust-inhibiting primer of water-soluble inorganic silicon solution and a process for preparation. The process comprises first, weighing water 5-40, inorganic silicon solution (TZG) 5-30, dispersing agent (5040) 0.2-0.6, defoaming agent (SA-3) 0.05-0.3, wetting agent (PE-100) 0.05-0.3, neutralizing agent (Amp-95) 0.05-0.3, and alcohol 1-5 into a synthesis autoclave according to percentage by weight of components and contents, dispersing for 10-20 minutes in low speed, second, weighing iron-oxide red 5-40, iron-oxide red earth 1-10, precipitated barium carbonate 1-10, zinc phosphate 0.3-5, and heavy calcium 1-10 into the synthesis autoclave according to percentage by weight of components and contents, and dispersing for 25-40 in high speed, third, sanding in a sand crusher, the degree of fineness is <=64um, fourth, weighing emulsion20-50, film former 0.5-3, and thickening agent 0.1-1 into the synthesis autoclave according to percentage by weight of components and contents, and adjusting the viscosity to be >=30, finally, getting end products after filtering. The invention has the advantages of environmental protection, strong tarnish proofness, excellent matching property with finish, long life span, low production cost and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-soluble inorganic silicon solution antirust primer and a preparation method thereof. Background technique [0002] At present, the anticorrosion treatment of metal materials and equipment requires a large number of antirust primers, and the existing iron red antirust primers all contain benzene organic solvents, causing serious environmental pollution; there is another water-soluble iron red antirust primer, Its rust resistance, matching with topcoat, service life, and product cost are all unsatisfactory. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a water-soluble inorganic silicon solution anti-rust primer which is environmentally friendly, has strong anti-rust performance, good compatibility with topcoat, long service life and low product cost. [0004] Another object of the present invention is ...
