Problems solved by technology

Its disadvantages are: 1. The production steps are cumbersome and the process is complex, 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. New process production The resulting product has stable performance, and its anti-separation and heat resistance are significantly better than the previous process

Abstract

The invention discloses a liquid calcium / zinc heat stabilizer. The liquid calcium / zinc heat stabilizer comprises, by weight, 10 parts to 15 parts of calcium oxide and / or calcium hydroxide, 10 parts to 20 parts of zinc oxide and / or zinc hydroxide, 30 parts to 40 parts of acid liquor, 1 part to 2 parts of azeotropic agents, 10 parts to 20 parts of saturated cycloparaffin solvents and 10 parts to 20 parts of heat-proof assistants. The invention further discloses a preparing method of the liquid calcium / zinc heat stabilizer and a device for implementing the method. According to the liquid calcium / zinc heat stabilizer, the product performance is stable, floccule can not be separated out during placing, the product is free of pungent smells, and the body of an operator can not be hurt. The preparing method of the liquid calcium / zinc heat stabilizer adopts a one-step method, the production technology is simplified, the unsafe factors in the production process are reduced, the production efficiency is improved, and the output rate is increased.

Description

technical field [0001] The invention belongs to the field of liquid stabilizers, and in particular relates to a liquid calcium / zinc heat stabilizer, a preparation method thereof and equipment for implementing the method. Background technique [0002] With the improvement of living standards, the requirements for environmental protection of industrial and household PVC products are increasing day by day. In the early 1990s, the compound lead salt stabilizer and cadmium barium zinc stabilizer were widely used. Among them, the heat stabilizers of lead salt and barium cadmium soap are cheap and have excellent performance. In developed countries, their output accounts for about 60% to 70% of the total heat stabilizers; in my country, the proportion is even larger, accounting for about 80% to 90%. %. For a long time, lead and cadmium stabilizers have dominated the consumer market of PVC heat stabilizers in the world. However, due to the high toxicity of lead salts and barium cadm...
