Problems solved by technology

[0003] The current fluorocarbon paint is mainly solvent-based, and because the solvent-based fluorocarbon paint contains high VOC, the solvent will be directly volatilized in the air during construction and cannot be recycled, resulting in waste of resources, polluting the environment, and causing some harm to construction workers. Toxic, implementing tools are difficult to clean
In addition, the paint film of solvent-based fluorocarbon paint is dense, the adhesion is poor, and local foaming is easy to form, which needs to be solved urgently

Abstract

The invention discloses a fluorocarbon coating good in adhesive force. The fluorocarbon coating good comprises the following raw materials in parts by weight: 40-50 parts of polyvinylidene fluoride, 15-25 parts of acrylic modified alkyd resin, 2-4 parts of a crosslinking agent, 20-30 parts of a urea composition, 4-10 parts of glass beads, 2-8 parts of calcined kaolin, 4-8 parts of a carbon nanotube, 1-4 parts of nano titanium dioxide, 1-2 parts of magnesium oxide, 1-2 parts of a waterproof agent, 1-3 parts of an antiageing agent and 1-3 parts of polyethylene wax. The fluorocarbon coating good in adhesive force disclosed by the invention is excellent in ageing resistance, excellent in strong chemical corrosion resistance and good in adhesive force, and avoids bubbling and falling phenomena in severe environments, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of fluorocarbon coatings, in particular to a fluorocarbon coating with good adhesion. Background technique [0002] Fluorocarbon paint has attracted the attention and favor of the decoration industry for its unique weather resistance, stain resistance, solvent resistance, acid and alkali resistance, and hydrophobic properties. [0003] The current fluorocarbon paint is mainly solvent-based, and because the solvent-based fluorocarbon paint contains high VOC, the solvent is directly volatilized in the air during construction and cannot be recycled, resulting in waste of resources, polluting the environment, and has certain harm to the construction workers. Poisonous, the implementation tool is difficult to clean. In addition, the paint film of solvent-based fluorocarbon paint is dense, the adhesion is poor, and it is easy to form local blisters, which needs to be solved urgently.
