A sort of method of fast manufacturing Rosin Resin, makes up the adhering to actions:
a. Crushing and grinding: Take 100kg of polished rosin with a pureness ≥ 99.2%, damage it and also grind it to 90-120 mesh;
b. Preheating: Include rosin ground to 90-120 mesh symphonious an as well as include it to the preheating pot. The pre-heating pot is shut as well as loaded with nitrogen defense. Include 1.8 kg of glycerin, include 0.75 kg of fumaric acid into the preheating kettle, include 0.10 kg of driver zinc oxide into the pre-heating kettle, warmth while stirring, and preheat to 260 ° C after 1.2 h;
c. Microwave catalysis: the preheated solution in the action b is discharged into the microwave activator, the microwave reactor is a closed air pressure type, and also a microwave generator as well as a stirring tool are set up, and also the power of the microwave generator is 10kW, And it is full of nitrogen security, switch on the microwave generator and stirring tool, as well as mix while accomplishing microwave radiation. The duration is 25 minutes, and also microwave catalysis is finished; the mixing device is suitable for the workplace of microwave radiation. Through microwave catalysis, it is beneficial to strengthen molecular vibration. Improve the thermal impact of reaction and enhance the rate of esterification reaction;
d. Ultrasonic catalysis: release the solution finished by microwave catalysis symphonious c into the ultrasonic reactor, which is closed and atmospheric pressure, and also full of nitrogen defense. The ultrasonic generator as well as mixing tool are set up on the ultrasonic reactor, and also the ultrasonic Generator, keep the frequency at 25kHz, keep it for 20min, then stop the ultrasonic generator, mix for 10min, after that stand still for 30min, keep the temperature of the ultrasonic activator at 265-270 ° C, repeat this action when; make use of ultrasonic cavitation Activity and mechanical action can increase the price of esterification reaction;
e. Pressurized catalysis: discharge the remedy completed by ultrasonic catalysis symphonious d into a pressurized activator. The pressurized activator is shut as well as loaded with nitrogen security. The service in the kettle was pressurized to 0.18 MPa, then stood still for 30 minutes, and then the stress in the pressurized response kettle was reduced to normal stress; the method of pressurization was made use of to enhance the rate of esterification response;
f. air conditioning: the solution that pressurizes and also militarizes in the step e is discharged right into the air conditioning kettle, and after the cooling is completed, the Rosin Material product 103.02 kg is acquired by the standard approach.
After inspection, the technological indications of Rosin Material products generated are: item shade (Hasson shade number) ≤ 50, acid worth ≤ 30mg KOH/g, softening point 100-105 ° C, thermal stability (in air): 180 ° C, 4h begin to alter shade.
