First, the introduction of acrylic resin:

Acrylic resin is also known as acrylate adhesive, and polyacrylate is a one-component or main component adhesive. Both thermoplastic and thermoset.

Second, the production process of acrylic resin production line adhesive:

    1) Add raw materials and emulsifiers to the emulsification tank for emulsification to obtain raw material monomers.

    2) The fully emulsified monomer and initiator are added to the jacketed reaction vessel, stirred and heated in a water bath to allow thorough mixing.

    3) When the temperature is raised to 80 ° C, the initiator is added, and acrylic acid and other mixed liquid are added dropwise from the dropping funnel, and the addition is completed within 2 hours.

    4) The temperature is controlled at 85 °C ± 2 °C, and then kept warm.

    5) Add the additive and continue stirring at 75 ° C for 1 hour.

    6) Cooling and discharging. A milky white viscous liquid is obtained.

    (Add distilled water and emulsifier to the four-necked flask equipped with a stirrer, thermometer, reflux condenser and feeding device, stir and heat in a water bath. When the temperature is raised to 80 ° C, add the initiator and add dropwise from the dropping funnel. A mixture of acrylic acid, butyl acrylate, styrene and vinyl acetate is added dropwise within 2 hours. The temperature is controlled at 85 ° C ± 2 ° C, and then kept warm. 1 h, adding tackifier and crosslinker, at 75 Stirring was continued for 1 h at ° C, then the temperature was lowered and discharged. The appearance of the product was milky white viscous liquid.)
