Abstract

The invention relates to an antirust paint and a preparation method thereof. The antirust paint with rust disclosed by the invention comprises the following components in parts by weight: 28-42 parts of silicone acrylic emulsion, 0.1-0.7 parts of sodium hexametaphosphate, 1.4-2.2 parts of alcohol ester 12, 0.9-2.1 parts of triethanolamine, 2.5-4 parts of aluminum dihydrogen triphosphate, 5.6-8.2 parts of titanium dioxide, 5.6-8.2 parts of barium metaborate, 1.8-4.1 parts of silica sol, 1.6-4.3 parts of potassium metasilicate, 0.15-0.35 parts of anti-rust agent, and 20-30 parts of vinyl ester resin. The preparation method comprises the following steps of: firstly, preparing vinyl ester resin, and weighing each component; putting the other components except for the vinyl ester resin into a mixer to mix and stir for 15-40 minutes to obtain mixed material I; grinding the mixed material I until the fineness of the grain size of the mixture is 20-40 microns; adding the vinyl ester resin to stir for 30-50 minutes, and then filtering by 300-350 meshes of filter cloth. The antirust paint with rust provided by the invention has the characteristics of low cost, high thermal resistance, corrosion resistance, flame retardant properties and the like, and can be widely applied to production and construction equipment.

Description

technical field [0001] The invention relates to an antirust paint and a preparation method thereof, in particular to an antirust paint with rust and a preparation method thereof. Background technique [0002] Anti-rust paint with rust is a kind of metal surface that can be directly coated on a certain rust layer, which can stabilize, passivate or transform rust, and turn active rust into a harmless substance, so as to achieve double rust prevention and protection. A class of antirust coatings, also known as rust surface coatings, rust coatings, and non-rust coatings. The use of anti-rust paint with rust for anti-corrosion treatment not only reduces or omits the rust removal process and reduces the cost of painting, but also greatly simplifies the painting process, thereby reducing labor intensity and reducing the harm of rust to the human body and environmental pollution. In recent years, anti-rust paints have developed rapidly, and various types of anti-rust paints with ru...
