Acrylic Emulsion And Acrylic Resin

1. Acrylic Emulsion

Acrylic emulsion is a water-based dispersion system, a high molecular polymer formed by emulsion polymerization of acrylic acid monomers and their comonomers.
The appearance is usually milky white or translucent liquid, and the particle size is generally 50-5000nm.
Mainly used in water-based coatings, adhesives, textile auxiliaries, papermaking auciliaries, etc.

2. Acrylic Resin

Acrylic resin is a type of thermoplastic or thermosetting polymer, formed by copolymerization of acrylic acid and its derivatives, usually in solvent-based or solid form.
Mainly used in coatings, inks, plastic modifiers, photocurable materials, etc.

The Connection Between Acrylic Emulsion and Acrylic Resin

Similar Ingredients: Both are copolymerized by acrylic acid and its esters, and have the same main chemical structure.
Complementary Functions: Acrylic emulsion is mainly used in water-based application systems, while acrylic resin is suitable for solvent-based or solid systems.
Cross-application: Some water-based acrylic resins can be converted into acrylic emulsions through emulsification and used in the field of environmentally friendly water-based coatings.

Differences in Main Equipment of Production Line

Equipment Category	Acrylic Emulsion Production Line	Acrylic Resin Production Line
Reactor	Mainly stainless steel emulsion polymerization reactor, which needs to be equipped with jacket or coil for heating and cooling	Mainly high temperature solvent polymerization reactor, which has higher material requirements (such as carbon steel+stainless steel or all stainless steel), high temperature resistance and corrosion resistance
Mixing System	Use high shear emulsification mixing to ensure uniform dispersion of monomers	Use high torque mixing system to ensure sufficient mixing of high viscosity materials
Heating/Cooling System	Mainly use steam heating or hot water circulation, the temperature control is relatively low (60-90℃)	Use heat transfer oil heating, can reach more than 200℃, and equipped with condensation recovery system
Emulsification Equipment	High shear emulsifier is required to ensure unifomr and stable emulsion particles	No emulsifier is required, mainly relying on solvent dissolution and stirring
Vacuum System	Generally not required or required at a low level	Efficient vacuum degassing system is required to remove low molecular weight substances adn residual solvents
Condensation Recovery System	Only a simple cooling device is needed	A condensation recovery tpwer is required to prevent solvent volatilization and reduce pollution
Storage and Delivery System	The emulsion can be directly stored in a stainless steel tank and transported using a corrosion-resistant pump	A closed storage system is required, equipped with a solvent recovery device
