Abstract

The invention belongs to the technical fields of paint and paint production technology, in particular relates to water-soluble low surface energy paint. The paint is characterized in that the paint comprises latex for low surface energy paint, preservative, deforming agent, wetting dispersant, pH regulator, pigment and filler, nanometer fine powder, film- forming additive, thickener, flatting agent and water. The pigment, filler and nanometer fine powder can be added in the paint of the invention according to applications and demands. The technology process of the invention comprises the following steps: firstly adding water in a dispersion tank in a defined ratio, stirring, then successively adding wetting dispersant, film- forming additive and bactericide in the dispersion tank according to a defined ratio to stir evenly, and finally adding latex for low surface energy paint, pH regulator, film- forming additive, thickener and flatting agent according to a ratio to disperse evenly. The water-soluble low surface energy paint of the invention has the advantage of scrubbing resistance, acid and alkali resistance, salt water and salt spray resistance, aging resistance, safety and environmental protection and easy construction; and the surface energy of the paint of the invention is lower, the contact angle between the paint and water is over 100 degrees, and the contact angle between the paint and methylene diiodide is 70 degrees.

Description

Technical field: [0001] The invention belongs to the technical field of paint and paint production technology, in particular to a water-based low surface energy paint and a preparation method thereof. Background technique: [0002] Low surface energy coatings have a series of excellent properties such as hydrophobicity, oleophobicity, self-cleaning, drag reduction, and anti-corrosion. Anti-graffiti and anti-stick coatings have potential application prospects. [0003] At present, in the field of low surface energy coatings, trifluoro resin coatings and tetrafluoro resin coatings are mostly used, but the surface energy of these two coatings is only relatively lower than that of epoxy coatings, acrylate coatings, polyurethane coatings, etc., and cannot achieve Anti-small advertisement paste requirements; therefore, some manufacturers at home and abroad have successively developed a series of anti-graffiti and anti-adhesive coatings, but these coatings still have various defic...
