Antibacterial and anticorrosive coating and preparation method thereof

Abstract

The invention discloses an antibacterial and anticorrosive coating. Firstly, a castor oil is used for cross-linking a prepolymer: the multifunctional-group structure in the castor oil can cross-link a polymer to a certain extent, the cross-linking degree of the polymer is increased, the interaction force among molecular chains is increased, molecular chain movement is hindered, water molecules cannot enter the molecular chains to swell the polymer, and the water absorption of an adhesive film is reduced; meanwhile, the castor oil is a triglyceride of fatty acid, due to long nonpolar fatty acid chains in molecules, the adhesive film has good hydrophobicity, and the water absorption is further reduced; meanwhile, ester groups in the castor oil have higher cohesive energy and can improve the tensile strength of the adhesive film; ethyl cellulose has better heat resistance and thermal plasticity, has good compatibility with PU and can improve the comprehensive property of the prepolymer; then the PU prepolymer is mixed with polysilsesquioxane for modification.

AI Technical Summary

Benefits of technology

This new type of material can be used on various materials like plastics or rubber products that may come into contact with bacillus spores during storage time without causing damage from these germs.

Problems solved by technology

This patented technology describes how different types of chemicals called casteroylene have been added during or after making up polymer resin for use in coating materials such as paints that make them more durability against environmental factors like weather conditions than older methods involving organosulfur chemistry. However, this method also results in decreased productivity due to increased manufacturing cost compared with alternative ways of producing these same substances. Therefore there needs to find another solution by replacing existing ingredients within the formula without losing their effectiveness on performance.
