Embodiment 1

[0029] The raw material components of the new environmental protection coating agent made of bio-inositol without phosphorus, fluorine, and heavy metals are: bio-inositol 3%, oxalic acid 20%, citric acid 5.0%, sodium dodecylsulfonate 2.0%, TX-10 3%, the balance is water, and the percentage is a mass percentage; the specific preparation is: first dissolve TX-10 and sodium dodecylsulfonate in water, then mix with the rest of the components, and then React at 85°C for 3 hours to obtain a film-coating agent.

Embodiment 2

[0031] The raw material components of the new environmental protection coating agent made of bio-inositol without phosphorus, fluorine, and heavy metals are: bio-inositol 2%, succinic acid 16%, sodium dodecylsulfonate 2.0%, OP-10 1.5%, the balance is water, and the percentage is mass percentage; the specific preparation is: first dissolve OP-10 and sodium dodecylsulfonate in water, then mix with the rest of the components, and then Under the condition of reaction for 5h, the film agent was obtained.

Embodiment 3

[0033] Phosphorus-free, fluorine-free, and heavy-metal-free film formulations are composed of: 4% bio-inositol, 10% oxalic acid, 5% succinic acid, 2% citric acid, 1% sodium dodecylsulfonate, OP- 10 1.5%, the balance is water, and the stated percentages are mass percentages; the specific preparation is: first dissolve OP-10 and sodium dodecylsulfonate in water, then mix them with the rest of the components, and then mix them at 75 Under the condition of ℃, react for 4h to obtain the film agent.

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 novel phosphorus-free, fluorine-free and heavy-metal-free environmental protection coating 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 Phosp...
