Embodiment 1

[0026] A novel anti-corrosion nano-composite coating in this embodiment is made up of the following raw materials in mass percentage: 35% modified resin, 15% glass flakes, a mixture of 30% xylene and cyclohexanone, 3% talcum powder, 5% phosphoric acid Zinc, 2% bentonite, 5% dibutyl phthalate, 3% p-hydroxybenzenesulfonic acid and 2% nanoscale titanium dioxide. Among them, the modified resin is epoxy-modified phenolic resin. The phenolic resin is mainly modified by mechanical mixing method to achieve interpenetration at the molecular level, thereby forming an interpenetrating network (IPN) structure and producing a synergistic effect.

[0027] Prepare the corrosion-resistant nanocomposite coating of the present embodiment, comprise the steps:

[0028] Step 1: using a mechanical mixing method to modify the phenolic resin to obtain a modified resin;

[0029] Step 2: mixing and stirring xylene and cyclohexanone according to the mass percentage of 60%: 40%, to obtain a mixture of x...

Embodiment 2

[0037] A novel anti-corrosion nanocomposite paint and preparation method thereof, made of the following raw materials in mass percentage: 25% novel modified resin, 13% glass flakes, 40% xylene and cyclohexanone mixture, 4% talcum powder, 6% Zinc Phosphate, 1% Bentonite Clay, 6% Dibutyl Phthalate, 2% P-Hydroxybenzene Sulfonic Acid and 3% Nanoscale Titanium Dioxide. Among them, the modified resin is polyamide modified phenolic resin, and the phenolic resin is mainly modified by the copolymerization method to realize interpenetration at the molecular level, thereby forming an interpenetrating network (IPN) structure and producing a synergistic effect.

Embodiment 3

[0039] A novel anti-corrosion nanocomposite paint and preparation method thereof, made of the following raw materials in mass percentage: 28% novel modified resin, 14% glass flakes, 35% mixture of xylene and cyclohexanone, 3% talcum powder, 8% Zinc Phosphate, 2% Bentonite Clay, 5% Dibutyl Phthalate, 3% Paraben Sulfonic Acid, and 2% Nanoscale Titanium Dioxide. Among them, the new modified resin is polyamide modified phenolic resin, which is mainly modified by copolymerization method to realize interpenetration at the molecular level, thereby forming an interpenetrating network (IPN) structure and generating synergistic effects.

Abstract

The invention discloses a novel corrosion-resistant nano composite paint which is composed of the following components in percentage by mass: 25-35% of modified resin, 13-15% of glass scale, 30-40% of xylene-cyclohexanone mixture, 2-4% of talcum powder, 5-6% of zinc phosphate, 1-2% of bentonite, 3-5% of dibutyl phthalate, 2-3% of p-hydroxy benzenesulfonic acid and 1-2% of nano titanium dioxide. The modified resin is synthesized by an advanced epoxy phenol formaldehyde modification process. The invention also discloses a preparation method of the composite paint. The nano composite paint has high adhesive force and excellent corrosion resistance for the metal matrix, avoids the problems of economic loss, environmental pollution and the like caused by equipment corrosion and inactivation, and has very important engineering application value.

Description

technical field [0001] The invention relates to a coating, in particular to a novel anti-corrosion nano composite coating and a preparation method thereof. Background technique [0002] During the development of sour oil and gas fields at home and abroad, usually due to SO 2 、H + , Cl - The existence of corrosive substances such as corrosive substances will cause serious corrosion damage and corrosion perforation in metal transportation pipelines and pressure vessels, and cause incalculable serious consequences. In addition, high temperature, high humidity and high salt spray conditions will also accelerate the corrosion of metal equipment, greatly reduce its structural strength, cause material and equipment failure, and seriously affect its service life and safety. [0003] The metal pipes and equipment working in the ocean will also have problems such as corrosion damage and corrosion failure due to the high salt content and high conductivity of seawater, which will sho...
