Embodiment 1

[0012] Example 1. Put 75% of urushiol resin into the reaction kettle first, then add 18% of silicone resin dropwise after heating up to 50°C, control the reaction temperature. , add 3% ammonia water and 1.5% to neutralize to PH = 7-8, heat 700-800°C to remove the water in the reaction, and carry out oil-water separation to obtain urushiol silicone resin.

Embodiment 2

[0013] Example 2, 30% of the urushiol silicone resin obtained in Example 1, wait until the temperature drops to 80°C, add 1% of epoxy resin, cool to room temperature, add 2% of nanometer rutile with a particle size of 100nm, and mix at a speed of 300 rpm The solid content of the coating is obtained in 10 minutes, and then an appropriate amount of leveling agent and defoamer are added, and the balance is xylene and n-butanol.

Embodiment 3

[0014] Example 3, 35% of the urushiol silicone resin obtained in Example 1, wait until the temperature drops to 80°C, add 2% of epoxy resin, cool to room temperature, add 3% of nanometer rutile with a particle size of 50nm, and mix at a speed of 300 rpm The solid content of the coating is obtained in 10 minutes, and then an appropriate amount of leveling agent and defoamer are added, and the balance is xylene and n-butanol.

Abstract

The invention relates to a urushiol-silicon nano anticorrosive coating and its preparing method, mainly solving the problem of worse hydrophobic and oleophobic properties of existing metal anticorrosive coatings. Its characteristic: it includes the following components in weight percent: urushiol-silicon resin 30%-40%, epoxy resin 1%-3%, and nano rutile 1%-3%. It has the resistance to strong acid, strong base and salt solution, high rigidity, shock resistance and temperature resistance, and low hydrophobic and oleophobic properties of the surface, i.e. it has the properties of prevent wax precipitation and fouling.

Description

Technical field: [0001] The invention relates to a metal anticorrosion coating, which belongs to an urushiol silicon nano anticorrosion coating and a preparation method thereof. Background technique: [0002] Several good anti-corrosion coatings have been launched at home and abroad. The application number is "00126583.0", and the coating named a new type of titanium chelated acetal ether discloses a technology. It uses urushiol as raw material, ammonia water or urethane Thorn as a catalyst, condensation reaction with formaldehyde to a certain molecular weight, and then chelated under the action of a titanium series catalyst, the coating film has high fullness, high hardness, high impact resistance, long storage time, and high solid content, but it is hydrophobic Poor water and oil repellency; the application number is "00110559.0", and the name is a kind of interface coating with high hydrophobicity, high thermal conductivity and high adhesion. The paint composed of paint ...
