Problems solved by technology

[0003] At present, although some anti-corrosion coatings are applied to chemical equipment, with the development of society, people put forward higher requirements for the performance of coatings used in chemical equipment. The existing coatings have corrosion resistance, high temperature resistance and flame retardancy. Poor, poor adhesion, easy to fall off during use, can no longer meet the needs of a rapidly developing society, and needs to be improved

Abstract

The invention discloses a special corrosion-resistant high-flame-retardancy paint for chemical equipment, which is prepared from a water-based polyurethane-acrylate composite emulsion, a water-based epoxy resin emulsion, a boric acid modified organic silicon resin, ammonium polyphosphate, pentaerythritol, melamine phosphate, hydroxyethyl methacrylate phosphate, tritolyl phosphate, carbon nanotubes, nano aluminum hydroxide, ceramic hollow microbeads, expanded perlite, modified attapulgite, fatty group polyisocyanate, an amino resin, N-phenyl-N'-cyclohexyl p-phenylenediamine, polyvinyl butyral, a film-forming assistant, a cosolvent, water, a coupling agent, carboxymethyl cellulose and assistants. The special corrosion-resistant high-flame-retardancy paint for chemical equipment has the advantages of favorable corrosion resistance, favorable high temperature resistance, high adhesive force and excellent flame retardancy. When being used in chemical equipment, the paint can not easily shed, has favorable protective effect, and can prolong the service life of the chemical equipment.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special corrosion-resistant and highly flame-retardant coating for chemical equipment. Background technique [0002] With the development of our country's economy, the process of industrialization is gradually accelerating, and industry has become increasingly important to the development of the national economy. Chemical equipment is an indispensable part of industrial development, and its normal operation is directly related to the normal production and operation of engineering projects. Under normal circumstances, due to the particularity of the environment in which chemical equipment is used, some oxidative-reductive gases and media are involved in the production of chemical companies. In addition, the production workshop has high humidity and high temperature, so it will A strong chemical reaction occurs on the surface of the equipment, resulting in corrosion. After bei...
