Embodiment Construction

[0010] 1 Add 100 kg of calcium powder in the mixing pot;

[0011] 2. Start the mixing pot at a low speed. The starting rotation speed of the mixing pot is 300-500 rpm. After the speed is stable, adjust to the high-speed rotating mixing pot. The speed of the high-speed rotating mixing pot is 1000 rpm. Pay attention to check the inside of the mixing pot Whether the temperature of the calcium powder rises steadily, so that the temperature of the calcium powder rises to 85°C;

[0012] 3 When the temperature in the mixing pot rises to 85°C, add 0.3 kg of activator and continue to heat up. The activator is made of palladium sulfate (PbSO 4 ) compounded with various additives;

[0013] 4 then add quality immediately and be 3 kilograms of plasticizers containing maleic anhydride, the mass content of maleic anhydride in this plasticizer is 3%, continue to heat up;

[0014] 5. Continue to rotate the mixing pot at a speed of 1000 rpm. When the temperature of the calcium powder in the m...

Abstract

The invention discloses a plastic additive calcium powder activating treatment method. The plastic additive calcium powder activating treatment method comprises the operation steps of starting a mixing pot at a low speed, feeding the calcium powder to the mixing pot for heating and stirring by rotating at a high speed, and increasing the temperature of the calcium powder to 85 DEG C, next, immediately adding an activator in the mass ratio of 2.5-3.5%o and continuously heating, next, immediately adding a plasticizer containing maleic anhydride in the mass ratio of 2.5-3.5%o and continuously heating, continuously stirring by rotating at 800-1200r / min to increase the temperature of the calcium powder to the range of 135-145 DEG C, next, adjusting the rotating speed to a low speed for rotating at 300r / min, and immediately discharging and cooling. According to the plastic additive calcium powder activating treatment method, the calcium powder is well mixed with the plastic, the grafting rate is increased; the original grafting rate is 60-70%, and the grafting rate of the technical scheme is above 90%; the plasticization property of the plastic is obviously improved to meet the use requirements.

Description

technical field [0001] The invention relates to a plastic additive processing method, in particular to a plastic additive calcium powder activation treatment method. Background technique [0002] With the development of plastic processing technology, plastic filling technology is becoming more and more mature. Adding filling materials can improve the performance of plastics and reduce the cost of plastics. However, in the process of use, it is found that the traditional additive calcium powder has the following shortcomings in the activation treatment: (1) There are many kinds of auxiliary materials, such as paraffin, zinc stearate, activator, compatibilizer, etc.; (2) ) The activation effect of calcium powder is not good, and the activated calcium powder has less grafting when processing plastics, which cannot meet the use requirements. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a plastic additive...
