Problems solved by technology

Its disadvantages are: 1. The production steps are cumbersome and the process is complicated, including feeding, salt formation, dehydration, compounding, pressure filtration, and finished product packaging processes. Each process is completed in different equipment, and semi-finished products need to be manually transferred. It is very troublesome; 2. Production The time period is long and the energy consumption is high, especially the dehydration and the two production processes of the filter press consume a lot of energy; 3. A large amount of acid mist is formed during high-temperature production, and the production of the equipment is not closed, which is harmful to the operators; 4. The new formula is new In the process, there is no bisphenol A and nonylphenol prohibited by the European Union, and the thermal stability time and processing performance have been significantly improved compared with the previous process

Description

technical field [0001] The invention belongs to the field of liquid stabilizers, and in particular relates to a liquid barium / zinc heat stabilizer, a preparation method thereof and equipment for implementing the method. Background technique [0002] With the rise of the PVC market, heat stabilizers as the main processing aids have undergone revolutionary changes. Since the industry was first developed, it was widely used in high-transparency liquid barium-cadmium-zinc and barium-cadmium paste heat stabilizers. With the rise of EU environmental protection requirements and Sony Electronics requirements, more and more countries have begun to use liquid barium-cadmium-zinc and barium Restricted use or prohibition of cadmium paste heat stabilizers. In this way, agricultural films, transparent shoe soles, car floor mats, and high-transparency toy materials that were widely used in the past are gradually replaced by liquid barium-zinc heat stabilizers. [0003] At present, the pr...
