Embodiment 1

[0033] Example 1: Heat stabilizer containing liquid barium and zinc (see the process flow chart figure 1 )

[0034] 1. Preparation of liquid barium carboxylate: In a 2000L enamel reactor, put 567kg of oleic acid, 66kg of benzoic acid, 92kg of p-tert-butylbenzoic acid, and 193kg of odorless kerosene into the 2000L enamel reactor. Put barium hydroxide octahydrate (Ba(OH)) into the reactor 2 ·8H 2 O) 321kg, heat up to 100℃ after the cast, start the normal pressure distillation dehydration reaction, about 2h basically no water vapor out, and then under the conditions of temperature 110℃, vacuum degree ≥ 0.09Mpa, the dehydration reaction is continued under reduced pressure until nothing Moisture is removed, dehydration is stopped and the temperature of the system is reduced to 85°C to obtain a clear and light yellow oily transparent liquid for use;

[0036] In a 2000L enamel reactor, put 234kg of isooctanoic acid, 78kg of benzoic acid, ...

Embodiment 2

[0040] Example 2: Heat stabilizer containing liquid barium and zinc (see the process flow chart figure 1 )

[0041] 1. Preparation of liquid barium carboxylate: In a 2000L enamel reactor, put 465 kg of oleic acid, 84 kg of benzoic acid, 86 kg of p-tert-butyl benzoic acid, and 193 kg of odorless kerosene into the 2000L enamel reactor. Start stirring and turn on the steam to heat up to 70°C. Put 425kg of barium hydroxide octahydrate into the reaction kettle. After the addition, the temperature is raised to 100°C to start the atmospheric distillation dehydration reaction. The reaction is about 2h, and the stirring is stopped when there is almost no water vapor. Then the temperature is 110°C, the vacuum degree is ≥0.09Mpa Under the conditions, the dehydration reaction is continued by vacuum distillation until anhydrous gas is removed, the dehydration is stopped, and the temperature of the system is cooled to 85°C to obtain a clear and light yellow oily transparent liquid for use;

[0046] Example 3: Heat stabilizer containing liquid barium and zinc (see the process flow chart figure 1 )

[0047] 1. Preparation of liquid barium carboxylate: In a 2000L enamel reactor, put 423 kg of oleic acid, 105 kg of benzoic acid, 123 kg of p-tert-butyl benzoic acid, and 193 kg of odorless kerosene into the 2000L enamel reactor. Start stirring and turn on the steam to heat up to 70°C. Put 512kg of barium hydroxide octahydrate in the reaction kettle. After the addition, the temperature is raised to 105°C and the normal pressure distillation dehydration reaction is started for 2h until almost anhydrous gas is removed. Then, under the conditions of temperature 110°C and vacuum degree ≥0.09Mpa, vacuum distillation Continue the dehydration reaction until anhydrous gas escapes, stop the dehydration and cool the system to 85°C for later use, to obtain a clear and light yellow oily transparent liquid.

Abstract

The invention relates to a heat stabilizer containing liquid barium and zinc, a preparation method thereof, and application thereof. The heat stabilizer consists of the following components in percentage by weight: 10%-30% of liquid carboxylate with the percentage by weight of barium as 5%-20%, 5%-30% of liquid carboxylate with the percentage by weight of zinc as 2%-15%, 10%-40% of composite phosphite ester, 1.5%-5% of beta-diketone, 0.5%-3% of antioxygen1010, 10%-40% of DOP (dioctyl phthalate), and 1.0%-5% of odourless kerosene. Liquid carboxylic acid metallic soap and auxiliary stabilizer are adopted to exert the synergistic effect, excellent heat stability and excellent initial-stage dyeing property and transparency are achieved for PVC (polyvinyl chloride) soft products, the production process is simple, only two steps are required, the production cost is low, the investment is low, and the heat stabilizer containing liquid barium and zinc is applicable to large-scale industrial production.

Description

Technical field [0001] The invention relates to a PVC stabilizer, in particular to a production method and application of a liquid barium zinc stabilizer applied to PVC soft products. Background technique [0002] Heat stabilizers are chemicals that can increase the stability of solutions, colloids, solids, and mixtures. They are called stabilizers. It can slow down reactions, maintain chemical balance, reduce surface tension, and prevent light, thermal decomposition or oxidative decomposition. [0003] The stricter requirements of environmental protection regulations are driving changes in heat stabilizers. In order to protect the human living environment, many countries have passed laws to restrict the application of toxic heavy metals in PVC processing. Among heat stabilizers, cadmium-free, low-lead, dust-free and replacement of lead salts have become the development focus of this industry. [0004] The consumption structure of heat stabilizers in different countries is...
