Abstract

The invention discloses a lignin-based super-hydrophobic coating and a preparation method thereof. The lignin-based super-hydrophobic coating is prepared from the following raw material components in parts by mass: 2 to 4 parts of covalently cross-linked lignin micro-nano spheres, 2 to 3 parts of trimethoxy (1H, 1H, 2H, 2H-13 fluorine n-octyl) silane, 1 to 2 parts of epoxy resin and 1 to 2 parts of curing agent. The preparation method comprises the following steps: preparing a covalent cross-linked lignin micro-nano sphere turbid liquid, preparing a lignin micro-nano sphere turbid liquid with low surface energy, preparing a super-hydrophobic adhesive prefabricated liquid, and coating a film. The lignin-based super-hydrophobic coating has the advantages of being low in cost, environmentally friendly, excellent in super-hydrophobic performance and the like, is a novel super-hydrophobic material and has good use value and application prospects, and the preparation method of the lignin-based super-hydrophobic coating has the advantages of being simple in process, mild in preparation condition, low in cost and the like, conforms to the green chemistry concept, is suitable for large-scale preparation, and is onvenient for industrial application.

Description

technical field [0001] The invention relates to a lignin-based superhydrophobic coating and a preparation method thereof. Background technique [0002] In production and life, the wettability of the material surface has an important impact on its processing and utilization. Superhydrophobic coatings have become a current research hotspot because of their functions such as self-cleaning, anti-fog, anti-mildew, and oil-water separation. In recent years, due to the increase in the durability requirements of superhydrophobic coatings, most research tends to use inorganic nanomaterials as precursors to prepare superhydrophobic coatings. However, there are still great challenges in cost control and environmental issues of inorganic nanomaterials. Therefore, there is an urgent need to develop a low-cost, green and environmentally friendly bio-based nanomaterial to replace inorganic nanomaterials for the preparation of superhydrophobic coatings. [0003] At present, there are mai...
