Abstract

The invention relates to a pipeline external wall anti-corrosion coating and a preparation method thereof, and belongs to the technical field of anti-corrosion coating preparation. The pipeline external wall anti-corrosion coating is prepared from, by weight, 40-50 parts of polytetrafluoroethylene, 20-30 parts of film-forming resin, 5-11 parts of titanium dioxide, 3-9 parts of fumed silica, 1-5 parts of film-forming auxiliaries, 1-3 parts of thickening agents, 11-15 parts of vinyl chloride, 25-35 parts of acetone, 11-15 parts of superhard aluminum oxide and 2-6 parts of antioxidants. The preparation method of the pipeline external wall anti-corrosion coating comprises the steps that the raw materials are evenly mixed and stirred for 20-25 min on the condition that the rotating speed ranges from 4000 r / min to 4500 r / min, ultrasonic treatment is conducted for 30-40 min on the conditions that the ultrasonic temperature ranges from 50 DEG C to 55 DEG C and the ultrasonic power ranges from 1000 w to 1300 w, and a finished product is obtained. The anti-corrosion coating is good in anti-corrosion effect, long in anti-corrosion service life, good in application property, resistant to water and weather, free of toxicity and environmentally friendly; in addition, the preparation cost is low, and the pipeline external wall anti-corrosion coating can be used on a large scale.

Description

technical field [0001] The invention relates to a pipeline outer wall anticorrosion coating and a preparation method thereof, belonging to the technical field of anticorrosion coating preparation. Background technique [0002] Corrosion takes a huge toll. Statistics show that the economic loss caused by corrosion in the world is about 1 trillion US dollars every year, which is 6 times the sum of natural disasters such as earthquakes, floods, and typhoons. [0003] The petrochemical industry is referred to as petrochemical industry. The petrochemical industry is a basic industry. It provides supporting services and services for agriculture, energy, transportation, machinery, electronics, textiles, light industry, construction, building materials, and people's daily life. It plays an important role in the national economy. occupy a pivotal position in the. Most of the metal equipment in the petrochemical industry is in the environment of acid, alkali, salt and high temperatu...
