Abstract
The invention discloses a beta-diketone organotin PVC heat stabilizer and a preparation method thereof, and belongs to the technical field of a PVC heat stabilizer. According to main points of the technical scheme, the beta-diketone organotin PVC heat stabilizer has a structural formula as shown in the specification, wherein R is phenyl or heptadecyl. The invention also discloses a preparation method of the beta-diketone organo tin PVC heat stabilizer. Advantages of an organotin stabilizing agent and a beta-diketone compound auxiliary heat stabilizer are combined, thus achieving the effects of the two substances. Then, the product is more convenient to use. In the preparation method of the beta-diketone organotin PVC heat stabilizer, the use of ultrasonic wave can avoid ammonium chloride which is generated after a reaction and doped in the product from affecting quality of the product; and by the use of nitrogen during the whole reaction, a solvent is not easy to volatilize under the condition of 0 DEG C. through nitrogen for solvent volatilization, crystallization can be promoted, and the influence of oxygen on the combination of a beta-diketone compound and stannous ion can be avoided.
