Embodiment Construction

[0032] Illustrate the present invention with the following examples, but do not limit the examples of the invention: (1) Instruments and manufacturing techniques used in Examples 1 to 6

[0033] According to the components listed in Table 1, 70% of the solvent and deionized water, compound emulsifier, initiator and all acrylate mixtures are added at room temperature in a container equipped with a high-shear mixer, at a speed of 1000r / min , pre-emulsified for 0.5h. The obtained emulsion is placed in a dropping funnel to pass through nitrogen to remove oxygen for use.

[0034] In another four-necked flask equipped with agitator, condenser, thermometer and dropping funnel, add another 30% solvent and deionized water emulsifier and initiator, nitrogen deoxygenation, heated to 80 ℃, after 15 minutes of heat preservation, take 2 hours, control the temperature at 80 ℃, add the monomer pre-emulsion dropwise under stirring, after the pre-emulsion is dripped, then add the organosilane ...

Abstract

The present invention relates to a fluorine and silicon contained copolymer resin emulsion and paint, it contains organo-fluorine compound, organo-silicon compound and other vinyl compound, in which the organo-fluorine compound is (methyl) acrylic fluorine-contained ester, and the organo-silicon compound is the compound containing alkylene and containing water-soluble siloxane group, and the other vinyl compound is that can be copolymerized with (methyl) acrylic fluorine-contained ester. Said invented fluorine-contained copolymer water paint has excellent cohesive force, and its formed paint film has excellent acid-resistant and alkali-resistant properties.

Description

Technical field: [0001] The invention relates to a copolymer resin emulsion and paint, in particular to a fluorine-containing, silicon-acrylic acid copolymer resin emulsion and paint. Background technique: [0002] Copolymers containing fluorine elements are well known as coatings for treating substrates such as fibers, paper, sand, ceramics, plastics, and metals. This is because fluorine atom compounds have unique low surface properties, so they are often used as hydrophobic and oil-repellent agents for fibers, mold release agents, protective coatings for building exterior walls, and special industrial materials such as optical materials. [0003] However, because of its low surface properties, it has poor adhesion to various substrates, especially emulsion-type coatings, so it is difficult to obtain a durable coating film. Usually, monomers containing hydroxyl groups and carboxyl groups are added to the polymer to improve the adhesion to common substrates. For example, 2-...
