Embodiment 1

[0026] 1. Preparation of calcium intermediates

[0027] In the reaction tank, put 100 parts of aliphatic carboxylic acid, 45 parts of aromatic carboxylic acid and 50 parts of oleic acid, and start stirring at a constant speed. Inject steam into the jacket of the reaction tank to heat the material, control the amount of steam in the jacket, slowly add 30 parts of aromatic carboxylic acid when the temperature of the material rises to 70°C-80°C, stir for 10 minutes to fully dissolve, Increase the temperature to 90°C and add 250 parts of Ca(OH) 2 , when Ca(OH) 2 When everything is put into the reaction tank, the temperature is kept at 100°C, the feeding port is locked, and a certain amount of nitrogen is introduced from the top of the reaction tank to completely discharge the steam in the reaction tank, so that the material can react without contact with the air at all, and the temperature rises , at the same time, in the reaction process, the water generated by the reaction of ...

Embodiment 2

[0035] 1. Preparation of calcium intermediates

[0036] In the reaction tank, put 120 parts of aliphatic carboxylic acid, 75 parts of aromatic carboxylic acid and 75 parts of oleic acid, and start stirring at a constant speed. Inject steam into the jacket of the reaction tank to heat the material, control the amount of steam in the jacket, slowly add 15 parts of aromatic carboxylic acid when the temperature of the material rises to 70°C-80°C, stir for 10 minutes to fully dissolve, Increase the temperature to 90°C and add 275 parts of Ca(OH) 2 . When Ca(OH) 2When everything is put into the reaction tank, the temperature is kept at 100°C, the feeding port is locked, and a certain amount of nitrogen is introduced from the top of the reaction tank to completely discharge the chamber steam in the reaction tank, so that the material can be reacted without contact with the air at all. Heating up, at the same time, during the reaction process, the water generated by the reaction of...

Abstract

The invention belongs to the field of PVC thermal stabilizers, and in particular relates to a calcium magnesium zinc composite thermal stabilizer, a preparation method and application thereof. Particularly, the preparation method comprises the following steps of: adding aliphatic carboxylic acid, aromatic carboxylic acid, oleinic acid and Ca(OH)2 in proportion; introducing nitrogen, rising a temperature and dewatering; discharging the oleinic acid to obtain a calcium intermediate; adding the aliphatic carboxylic acid, the aromatic carboxylic acid, the oleinic acid and Mg(OH)2 in proportion; introducing the nitrogen, rising the temperature and dewatering; discharging the oleinic acid to obtain a magnesium intermediate; adding the aliphatic carboxylic acid, the aromatic carboxylic acid, the oleinic acid and the Zn(OH)2 in proportion; introducing the nitrogen, rising the temperature and dewatering; discharging the oleinic acid to obtain a zinc intermediate; adding the calcium intermediate, the zinc intermediate, the magnesium intermediate, higher alcohol, phosphite ester, an anti-ageing agent, a light stabilizer and the oleinic acid in proportion; and mixing to prepare the calcium magnesium zinc composite thermal stabilizer. The calcium magnesium zinc composite thermal stabilizer has high weather resistance, ageing resistance, light resistance, and heat resistance.

Description

[0001] technical field [0002] The invention belongs to the field of PVC heat stabilizer preparation, and particularly relates to a magnesium-calcium-zinc composite heat stabilizer with good weather resistance, aging resistance, light resistance and heat resistance, and a preparation method and application thereof. Background technique [0003] In recent years, global health, safety, and environmental regulations have become increasingly stringent. "Green" plastics have become the development direction of the plastics industry in the 21st century, while high-efficiency, multi-functional, non-toxic, and pollution-free are the development trends of plastic additives. On the one hand, the current domestic research on magnesium, calcium and zinc is still in the exploratory stage. The stability of the domestic calcium soap zinc soap compound stabilizer is relatively poor, and the compatibility with PVC is not good, and the calcium soap is transparent when the amount of calcium ...
