Embodiment

[0036] The present embodiment provides a PVC plastic stabilizer prepared by the following components:

[0037]

[0038] The preparation method of the PVC material stabilizer comprises the steps of:

[0039] Step 1, vegetable oleic acid, overbasic metal barium, barium monohydrate, zinc oxide, dibenzoylmethane, diphenylisodecyl phosphite, antioxidant, butyl stearate, solvent oil, the temperature is 130°C heat preservation reaction for 2 hours;

[0040] Step 2. After the reaction is complete, control the temperature at 115°C for vacuum dehydration for about half an hour;

[0041] Step 3: Press filter the product obtained in Step 2, and control the temperature at 90° C. to obtain the finished product.

Abstract

The invention provides a PVC (Polyvinylchlorid) plastic stabilizer and a preparation method thereof. The PVC plastic stabilizer is prepared from the following components: vegetable oil acid, high-alkaline metal barium, barium monohydrate, zinc oxide, dibenzoylmethane, diphenyl isodecyl phosphite, an antioxidant, butyl stearate, and solvent oil. The liquid barium-zinc composite stabilizer is prepared by a one-step method, meets the requirements of innocuity, thermal stability, light stability, transparency, good weatherability and the like, and is especially suitable for the PVC products industry with relatively high environmental protection requirements such as food packaging materials, children's toy film class I, medical supplies and the like; and likewise, a stabilizing system has the functions of inhibiting and absorbing HCl, maintains initial coloring, and controls'zinc burning' phenomenon and precipitation and exudation results to achieve the stabilizing effect.

Description

technical field [0001] The invention relates to a PVC heat stabilizer, in particular to a PVC plastic stabilizer and a preparation method thereof. Background technique [0002] The application range of PVC products is extremely wide. With the increasingly stringent environmental protection requirements, the raw materials used in the PVC industry-environmental protection stabilizer products are also tending to be diversified and diversified, especially for children's products and medical products. The PVC plastic processing aid liquid barium zinc stabilizer should have the characteristics of high efficiency, multi-function, non-toxic and pollution-free. [0003] The traditional processing of PVC plastic additives is mainly based on the composite production process, that is, after the required monomer soap barium oleate and zinc oleate are produced separately, the raw and auxiliary materials are selected for composite processing according to the production needs of their own p...
