Abstract

The invention discloses a novel fluorocarbon-graphene-acrylic polymer and a preparation method thereof. The polymer is prepared from components in parts by weight as follows: 5-30 parts of a fluorocarbon monomer, 0.01-5 parts of graphene, 0.5-5 parts of a silicon-containing monomer, 5-35 parts of an acrylate monomer, 1-4 parts of a self-crosslinking monomer, 30-80 parts of a solvent and 0.1-1 partof an initiator. The polymer further contains an emulsifier when in a form of solution or emulsion. A solution or emulsion prepared from the novel fluorocarbon-graphene-acrylic polymer has good waterproof, anti-corrosion, anti-power, oil-repellent, anti-fouling, aging-resistant and self-cleaning functions and the like, and is applicable to waterproofing, corrosion resistance, power resistance, oil repellency, fouling resistance, aging resistance and self-cleaning of polyester fibers, polyamide fibers, cotton fibers, cotton fibers / polyester fibers, cotton fibers / hemp fibers, artificial cottonfibers and (building, electronic and metal) coatings.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a novel fluorocarbon graphene acrylic acid polymer and a preparation method thereof. Background technique [0002] Fluorocarbon graphene polymer material refers to the product after the hydrogen atoms on the main chain or side chain of ordinary polymers are replaced by fluorine atoms. Fluorocarbon graphene polymer materials have excellent properties, such as strong hydrophobicity, strong stability, including thermal stability, chemical stability, anti-oxidation stability, non-stickiness, biocompatibility and good gas permeability, These properties make fluorine-containing materials well-used in many fields, such as protective coatings and lubricants in the field of microelectronics. [0003] Fluorinated fabric finishing agent is an important textile finishing agent. After finishing with fluorine-containing fabric finishing agent, the fabric can show the characteristics that ord...
