Abstract

The invention discloses a graffiti-proof and easy-cleaning acrylate flatting agent modified by fluorine and silicon, which is prepared by mixing raw materials of acrylate monomer, fluoro-acrylate monomer, organosilicon monomer, initiator, and solvent. The flatting agent can make coatings have functions of graffiti prevention and easy cleaning; the surfaces of the coatings are marked by a solvent marking pen, the marks can be completely removed by dry erasing; and the hydrophobicity and the oleophobic property of the flatting agent are also greatly improved.

Description

Technical field: [0001] The invention relates to a leveling agent for paint. Background technique: [0002] Existing coatings do not have anti-graffiti and easy-cleaning functions, so that the scope of use is limited. Invention content: [0003] The object of the present invention is to provide an anti-graffiti and easy-cleaning fluorosilicon modified acrylate leveling agent with anti-graffiti and easy-cleaning functions and a production method. [0004] Technical solution of the present invention is: [0005] An anti-graffiti and easy-to-clean fluorosilicon modified acrylate leveling agent is characterized in that it consists of the following raw materials by weight: [0006] Acrylate monomer 5-30% [0007] Acrylic fluorine monomer 1-15% [0008] Silicone monomer 20-70% [0009] Initiator 1-30% [0010] Solvent 20-70%. [0011] The acrylate monomers are lauryl methacrylate, stearyl methacrylate, butyl acrylate or isooctyl acrylate. [0012] The fluoroacrylate mono...
