Acrylic resin manufacturing process

Acrylic resin production process:

1. Feeding: put the bottom material in the reaction kettle;

2. Temperature rise and dropwise addition: When the temperature rises to the specified temperature or there is reflux (usually reaching the boiling point of the bottom raw material), the monomer, solvent and initiator are added dropwise through the high-level tank;

3. Temperature control: At this time, the reaction of the acrylic resin is relatively violent, and the temperature needs to be controlled within a reasonable range.

It should not be too high. If it is too high, the reaction will be too intense, and if the control is not good, it will overflow.

The temperature should not be lower than a reasonable temperature range. If it is too low, the reaction will be insufficient, and the molecular weight and performance of the acrylic resin will be greatly affected.

4. Insulation: This stage is to make the residual monomer of acrylic acid react more fully. The temperature in this stage is basically a stage of slow decline. Appropriate heating is carried out for insulation, so that the residual monomer and the residual initiator can fully react.

5. Adjust the viscosity and measure the solid content: adjust the viscosity to the specified range, and detect the solid content and other indicators.

6. Cooling and packaging: After the index is qualified, cool down to below 80 degrees and pack.

Commonly used equipment for acrylic resin synthesis is as follows:

1: batching tank→dropping tank→reaction kettle→horizontal condenser→water separator→filter, etc.

2: Mixing system: Anchor frame type and one-line pulp are generally used in combination.

3: Weighing and feeding, the dripping control is true.
