Embodiment

[0006] Step 1: Prepare liquid A first, add 38 parts of oil-based phenolic paint to the chemical reaction kettle, start the agitator at a speed of 35 rpm, slowly add 22 parts of iron oxide red and 7 parts of zinc oxide at room temperature, and react 0.5 hours; raise the temperature to about 40°C, add 12 parts of precipitated barium sulfate, 8 parts of calcium carbonate, 0.4 parts of 4% cobalt naphthenate, 0.15 parts of 3% manganese naphthenate, and 0.6 parts of 10% lead naphthenate , 0.25 parts of zinc stearate, stirring and heat preservation reaction for 1.5 hours. Cool to obtain liquid A.

[0007] Step 2: To prepare liquid B, put 5.6 parts of 200# paint solvent gasoline into the container, add 3 parts of epoxy resin and 3 parts of polyamide curing agent in turn and stir into a uniform liquid state.

[0008] Step 3: When using, mix A liquid and B liquid directly, stir evenly and use.

Abstract

The invention discloses a preparation method of an oily iron oxide red antirust paint. The product of the invention is an oily metal antirust paint, and the working principal thereof is that the density of a paint film is improved and the permeability of the paint film is reduced by means of the stability of the antirust paint in physical and chemical properties and excellent filling property of the antirust paint, thus the antirust effect is realized. The antirust paint has the advantages that: the paint film has excellent adhesive force and impact resistance, good oiliness, solvent resistance, water resistance and saline resistance, outstanding compatibility with epoxy type finish, polyurethane type finish and chlorinated rubber finish, and superior interlayer adhesive force. The raw materials adopted for producing the paint are as follows: oil-based phenolic aldehyde paint, iron oxide red, zinc oxide, precipitated barium sulfate, calcium carbonate, 4% of cobalt naphthenate, 3% of manganese naphthenate, 10% of lead naphthenate, zinc stearate, No. 200 paint solvent gasoline, epoxy resin and a polyamide curing agent.

Description

Technical field: [0001] The product of the invention belongs to the field of chemical building materials. Specifically relates to a preparation method of metal antirust paint. Background technique: [0002] Coatings that can protect metal surfaces from chemical or electrochemical corrosion of the atmosphere, sea water, etc. are called antirust paints. It can be divided into two categories: physical and chemical antirust paint. Physical antirust paint relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter depends on the chemical rust inhibition of antirust pigments Function, such as red lead, zinc yellow antirust paint, etc. Used for rust prevention of bridges, ships, pipelines and other metals. The antirust paint currently used is roughly two types: oily and water-based. Oil-based anti-rust paint makes it difficult t...
