This article is enough to understand acrylic emulsion!

1.Acrylic Emulsion

Acrylic emulsion is a milky white or nearly transparent viscous liquid. Acrylic emulsion is an emulsion copolymerized from pure acrylic ester monomers. It is a small-particle, multi-purpose, and high-performance emulsion.

2.Features

Excellent gloss and transparency

Water resistance and weather resistance

Alkali resistance and stain resistance

Good adhesion

Non-toxic, non-irritating, harmless to the human body, low pollution, in line with environmental protection requirements

3.Application

△ Suitable for a variety of paint formulas, mainly used for building waterproofing, casein glue, water-based ink, plywood glue, etc.

△ High-gloss and semi-gloss paints

△ Masonry, wood and steel surfaces

△ Used to prepare flat, semi-gloss and high-gloss latex paints, and can also be used to prepare high-quality floor, cement tile and tennis court finishing paints.

4.Classification

Emulsions can be classified into: interior wall emulsions, exterior wall emulsions, real stone paint emulsions, elastic emulsions, liquid granite paint emulsions, waterproof emulsions, sealing emulsions, etc. by product use.

According to the composition of the product, it can be divided into: pure acrylic emulsions, silicone acrylic emulsions, styrene acrylic emulsions, vinegar acrylic emulsions, etc.

5. Composition of lotion

☆Monomer:

Pure acrylic acid: acrylic acid, methyl acrylate, ethyl acrylate, methyl methacrylate, butyl methacrylate, etc.

Comonomer: vinyl acetate, styrene, acrylonitrile, dibutyl maleate, butadiene, etc.

Functional monomer: methacrylic acid, maleic acid, fumaric acid, methacrylamide, etc.

Crosslinking monomer: hydroxymethyl acrylamide, hydroxyethyl methacrylate, hydroxypropyl methacrylate, divinylbenzene, etc.

☆Initiator:

According to the reaction system: water-soluble initiator, oil-soluble initiator

According to the free radical generation system: thermal decomposition type, redox type

☆Emulsifier: anionic, cationic, nonionic, amphoteric

☆Neutralizer:

Anionic water-based resin: alkaline neutralizer, ammonia, amines.

Cationic water-based resin: organic acid neutralizer, formic acid, acetic acid, lactic acid, etc.

☆Co-solvents: mainly alcohols, ethanol, isopropanol, n-butanol, tert-butanol, etc.
