Problems solved by technology

However, due to the poor performance of the traditional styrene-acrylic emulsion coating film in terms of hardness, adhesion, solvent resistance, and water resistance, it limits its scope of use to a large extent. Therefore, the modification method is used to obtain more Excellent performance is an important breakthrough to further expand the scope of use of styrene-acrylic emulsion based on the excellent characteristics of styrene-acrylic emulsion
In recent years, research on the modification of styrene-acrylic emulsions has achieved good results, such as modified styrene-acrylic emulsion coatings with stronger coating film hardness or better corrosion resistance, but most modified styrene-acrylic emulsions Unable to combine more performances, there are more obvious defects

Abstract

The invention discloses an epoxy silane coupling agent-organic fluorine composite modification styrene-acrylic emulsion and a preparation method thereof. Methyl methacrylate, styrene, n-butyl acrylate, methacrylic acid, dodecafluoroheptyl methacrylate, 3-glycidyl ether oxy-propyl trimethoxy silane, octaphenyl polyoxyethyiene, sodium dodecyl benzene sulfonate, ammonium persulfate and distilled water are used as main raw materials; through an emulsion polymerization mode, the epoxy silane coupling agent-organic fluorine composite modification styrene-acrylic emulsion is prepared. Compared with the conventional styrene-acrylic emulsion, the prepared modified styrene-acrylic emulsion has the advantages of more excellent properties such as film coating intensity, film coating adhesion power, film coating water absorption rate, film coating anti-corrosion performance and emulsion conversion rate. The film coating pencil hardness is 4H or higher; the adhesion power reaches grade 1 or higher;the water absorption rate is 8 percent or higher; the emulsion conversion rate is 99 percent or higher; great application prospects are realized.

Description

technical field [0001] The invention relates to an epoxy silane coupling agent-organic fluorine composite modified styrene-acrylic emulsion and a preparation method, belonging to the technical field of architectural coatings. Background technique [0002] Styrene-acrylic emulsion has low manufacturing cost, and has the characteristics of non-toxic, odorless, non-flammable, less pollution, weather resistance, stain resistance, and excellent corrosion resistance. It is widely used in the field of coatings. However, due to the poor performance of the traditional styrene-acrylic emulsion coating film in terms of hardness, adhesion, solvent resistance, and water resistance, it limits its scope of use to a large extent. Therefore, the modification method is used to obtain more Excellent performance is an important breakthrough to further expand the scope of use of styrene-acrylic emulsion on the basis of utilizing the excellent characteristics of styrene-acrylic emulsion. In rece...
