Embodiment 1

[0037] Preparation of barium fatty acid:

[0038] Mix 100kg oleic acid, 300kg isooctanoic acid, 130kg barium hydroxide and 300kg ethylene glycol butyl ether, stir, slowly heat up to 150°C, react for 1.5 hours, distill under reduced pressure for 5 minutes, and dry at 80°C to obtain 800kg of barium fatty acid.

Embodiment 2

[0040] Preparation of Zinc Fatty Acid:

[0041] Mix 100kg of isooctanoic acid, 80kg of p-tert-butylbenzoic acid, 30kg of zinc oxide and 80kg of diethylene glycol butyl ether, stir, slowly heat up to 150°C, react for 1.5 hours, distill under reduced pressure for 5 minutes, and dry at 80°C. 280kg of zinc fatty acid was obtained.

Embodiment 3

[0043] Mix 40kg of fatty acid barium, 10kg of fatty acid zinc and 10kg of diethylene glycol butyl ether evenly, stir, then heat to 75°C, then add 35kg of phenol-free phosphite, keep warm for 30 minutes, and then add 10kg of tetrakis [methyl-β -(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester and 7kg oleoylbenzoylmethane, heat at 85°C for 30 minutes, cool and filter to obtain zinc-based liquid compound Heat stabilizer 112kg.

Abstract

The invention discloses a zinc base liquid composite heat stabilizer and a preparation method of the zinc base liquid composite heat stabilizer. The heat stabilizer is formed by the following raw materials according to mass ratio: 40-60 parts of barium fatty acid, 10-18 parts of zinc fatty acid, 10-35 parts of phosphite ester, 2-7 parts of beta-diketone, 1-10 parts of anti oxidizers and 10-20 parts of solvent, wherein barium in the barium fatty acid accounts for 10-15 percent in mass fraction, zinc in the zinc fatty acid accounts for 8-12 percent in mass fraction, and one of diethylene glycolmonobutylether, butyl cellosolve, dipropylene glycol methyl ether, tripropylene glycol methyl ether, white oil or coal oil is used as the solvent; the zinc base liquid composite heat stabilizer can effectively delay zinc burning phenomenon in a system, the PVC (polyvinyl chloride) thermal stabilization is improved, auxiliaries and PVC resin selected in the system have more approximate refractive indexes, a prepared PVC product has good transparent performance and good anti-precipitation property.

Description

(1) Technical field [0001] The invention relates to a zinc-based liquid composite heat stabilizer and a preparation method thereof, in particular to a zinc-based liquid composite heat stabilizer for polyvinyl chloride (PVC) and a preparation method thereof. (2) Background technology [0002] Polyvinyl chloride (PVC) is the second largest plastic species next to polyethylene. It has high strength, excellent corrosion resistance and insulation. Its products are widely used in construction, electrical appliances, toys, packaging and other industries. However, PVC has its structural defects. It is unstable when heated and decomposes to release hydrogen chloride gas. The solution is to add heat stabilizers to PVC processing. [0003] Commonly used heat stabilizers mainly include lead salts, metal soaps and organic tins. Lead salt stabilizer is cheap and has good heat stabilizing effect. It is the most used heat stabilizer, but its toxicity is high, which seriously endangers huma...
