Abstract

The invention belongs to the technical field of emulsions and in particular relates to an aqueous modified acrylic emulsion as well as a preparation method and application thereof. The aqueous modified acrylic emulsion comprises the following specific formulae: 56% of water, 1-2% of an emulsifier, 1-6% of a fluorine-containing monomer, 11-16% of butyl acrylate, 8-15% of methyl methacrylate, 3-11%of styrene, 0.25-0.5% of beta-acroloyl propionic acid, 0.25-0.5% of acrylic acid, 1-4% of hydroxyethyl acrylate, 0.5-3% of vinyl versatate, 0.3-0.8% of acrylamide, 1-2.5% of diacetone acrylamide (DAAM), 0.5-1.25% of adipic dihydrazide (ADH), 0.2-0.4% of persulfate and 0.6-1.5% of organic amine AMP-95. The emulsion provided by the invention is good in solvent resistance, weather resistance, stain resistance, artificial aging resistance and weather resistance, and in addition, excellent in scratch resistance, T bending resistance and impact properties.

Description

technical field [0001] The invention belongs to the field of emulsion technology and relates to a fluorine-modified acrylic emulsion, in particular to a water-based fluorine-modified acrylic emulsion and its preparation method and application. Background technique [0002] Coil coatings are different from general industrial coatings. It adopts the production process of coating first and then processing, which can save a lot of cost. However, the requirements for the coating are very high. On the one hand, it must have sufficient hardness to prevent scratches, and on the other hand, it must maintain sufficient flexibility to prevent the coating from cracking during processing. After painting, the coating should also have excellent weather resistance, water resistance, etc., to meet the different needs of users. [0003] At present, almost all coatings for coil materials are oil-based paints. Because they contain a lot of solvents, they have a great impact on the environment ...
