Abstract

The invention relates to a novel non-phosphorus, fluoride-free and heavy-metal-free environmental-friendly coating film agent prepared from biological inositol and a preparation method and application of the novel non-phosphorus, fluoride-free and heavy-metal-free environmental-friendly coating film agent. The novel non-phosphorus, fluoride-free and heavy-metal-free environmental-friendly coating film agent is prepared from the biological inositol and polybasic organic acid in the mol ratio of (1:1)-(1:10). The novel non-phosphorus, fluoride-free and heavy-metal-free environmental-friendly coating film agent has the advantages that the prepared coating film agent is free from phosphorus, fluoride and heavy metal and is truly environmental-friendly; the coating film agent is high in anti-rust performance, excellent in coupling force and adhesive force for molding powder and paint, low in investment and using requirement, applicable to different kinds of metal, high in adhesive force, and capable of meeting the ROHS (Restriction of the use of certain Hazardous Substances) compliant and solving the problems of high fluorine content, poor stability during use, complexity in operation and control and the like of an existing non-phosphorus coating film agent fundamentally.

Description

technical field [0001] The invention relates to a phosphorus-free, fluorine-free and heavy metal-free environmental protection film agent made of bio-inositol, a preparation method and application thereof, belonging to the field of metal surface treatment. Background technique [0002] As a metal surface treatment agent, the film agent can prevent the metal surface from oxidizing, and can also enhance the adhesion of the paint film when the subsequent paint film is sprayed. It is widely used in the field of metal products. [0003] Existing coatings include phosphorus-containing coatings and non-phosphorus coatings. Phosphorus-containing film agents cause serious environmental pollution. With the strengthening of environmental protection work, the pollution of phosphorus has been highly valued by relevant departments and enterprises at home and abroad. There are many regions and cities in China that prohibit the use of phosphorus-containing washing powder and Phosphorus-con...
