Abstract

The invention discloses a calcium-zinc composite stabilizer production system and a production process thereof, belonging to the technical field of heat stabilizer production. The calcium-zinc composite stabilizer production system of the present invention comprises a stirring device, a drying device and a pulverizing device which are sequentially arranged and connected according to the technological process; wherein: the stirring device includes a reaction kettle, a stirring rod, a discharge pipe and a water pump, and the The stirring rod is directly inserted into the middle and lower part of the reactor, the discharge pipe communicates with the bottom of the reactor, and the water pump communicates with the upper part of the reactor through a water pipe; the drying device is a vacuum freeze-drying device. Compared with the stabilizers of the prior art, the calcium-zinc composite stabilizer prepared by the production process of the present invention adopts three groups of components in a ratio of 1:1 for the first time, and achieves cold resistance, heat resistance and smoothness when applied to high-grade plastics. , toughness, wear resistance and other unexpected technical effects, and the service life has been proved by destructive tests, at least increasing the original service life by more than 20%.

Description

technical field [0001] The invention relates to the technical field of heat stabilizer production, in particular to a calcium-zinc composite stabilizer production system and a production process thereof. Background technique [0002] PVC and PE are general-purpose plastics with the largest output and consumption. The output of PVC in the world has exceeded 100 million tons, and that of my country is 17.8 million tons. Due to the poor thermal stability of PVC and the difficulty in processing, about 4% of heat stabilizers must be added during molding and processing. Our country consumes about 700,000 tons of heat stabilizers every year. [0003] Traditionally, the heat stabilizers are mainly lead salt heat stabilizers. Because lead salt stabilizers are highly toxic, bioaccumulative, and easy to generate dust, it will cause chronic problems for operators during production and use. Lead poisoning, and will cause serious environmental pollution after being discarded. With the ...
