Molecular Self-assembly of Water-based Industrial Coatings Successfully Developed
The technical progress of industrial coatings and the product development of new industrial coatings in the world have achieved very promising results, but there are still some shortcomings or weaknesses. For example: inorganic nanopowder filled modified coatings.
Due to the special effect of nanoscale solid phase particles with extreme selectivity, the synergy between different nanomaterials and other materials in the coating ingredients is extremely different. When formulating the materials, a large number of laboratory tests and testing analysis must be conducted. This not only increases the difficulty of selecting the formulation grouping materials, but also increases the cost and raises the cost. In addition, due to the large specific surface area of nanomaterial particles and high surface free energy, nanoparticles are very easy to coalesce into clusters again, forming a dispersion and stability problem in the production process.
Some nanoparticles have photocatalytic effect, forming a problem of negative impact on coating life. Filling modification with inorganic nanopowders requires nanoparticles to play a special effect, which requires high purity of nanoparticles, forming a rather complicated problem of selecting and testing nanomaterials.
Even water-soluble resin nano-coatings, because of the limitations of raw materials, process equipment, additives and other production conditions, there are also widespread defects such as soft paint film, long drying time, poor storage stability and lack of scrubbing resistance. To solve these problems, all necessary engineering measures are needed, which will certainly increase the production cost.
At present, we have not yet seen a molecular self-assembling industrial coating in the market that is environmentally friendly, saves raw materials and has good application effect, and the process is relatively simple. The molecular self-assembled water-based industrial paint developed in China is a molecular self-assembled water-based industrial paint. Its main technology lies in the formulation group material is: acrylic acid epoxy polyester nanoemulsion. The formulation group materials for preparing the acrylic acid epoxy polyester nanoemulsion as described are: adipic acid, phthalic anhydride, linseed oil fatty acid, epoxy resin E51, xylene, butyl acetate, methacrylic acid, methyl methacrylate, butyl methacrylate, hydroxyethyl methacrylate, n-dodecyl sulfate, benzoyl peroxide, n-butanol, and Zhuoxian liquid.
The present invention can eliminate the disadvantages of organic solvent-based coatings such as massive emission of volatile substances, serious pollution of the environment and waste of valuable resources.
This self-assembled water-based industrial coating is mainly applied to the surface paint installation of industrial products such as automobiles, harvesting machinery, engineering machinery, ships, railroad light rail buses, aerospace vehicles and household appliances.
