Water-based high-temperature-resistant anti-corrosion composition

Abstract

The invention discloses a water-based high-temperature-resistant anti-corrosion composition which comprises the following components in parts by weight: 45-90 parts of a polymer matrix, 15-70 parts of compact filling powder, 0.5-4 parts of rare earth metal, 5-40 parts of a dispersing agent, 2-25 parts of a flatting agent and 10-30 parts of an inorganic adhesive. The water-based high-temperature-resistant anti-corrosion composition is good in anti-corrosion performance, does not re-rust in a high-salt environment and particularly has more outstanding performance in corrosion environments such as salt mist and acid rain, the ultraviolet aging resistance is 3-5 times that of a traditional coating, the salt mist test can reach 2400 h or above, and the service life of the water-based high-temperature-resistant anti-corrosion composition meets the requirement of Centennial Project. The water-based high-temperature-resistant anti-corrosion composition disclosed by the invention is high-temperature-resistant and non-combustible, is an A-grade fireproof non-combustible material, has ultrahigh surface hardness which can reach 4-9H, particularly outstanding scratch resistance and good impact resistance, and can meet the requirements of various special environments.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based high temperature resistant anticorrosion composition. Background technique [0002] The annual direct economic loss caused by corrosion accounts for about 1%-4% of GDP, corroded and rusted steel accounts for about 20% of my country's annual steel output, and the loss is about 800 billion yuan, accounting for about 3% of GDP. has received more and more national attention. In order to enhance adhesion and surface effect, traditional anti-corrosion materials still use oil-based organic chemical paints or anti-corrosion coatings. During the process of manufacture and use, VOCs are continuously released, and chemical substances such as formaldehyde, benzene, arsenic, and chromium are harmful to the environment and human body. It is one of the main sources of pollution of water, soil and air. [0003] The anticorrosion of steel structures such as outdoor metal surfaces and ship m...
