Problems solved by technology

[0003] Synthetic resin materials show certain side effects in the application process, such as not easy to decompose, environmental pollution, etc. In addition, stabilizers, plasticizers, crosslinking agents, etc. are used in the production process of plastic materials on the market, causing environmental pollution of many plastic products Very large, it is very easy to cause harm or damage to the ecological environment after use, and cause potential huge damage to human health
As a key component of plastics, plastic additives have a major impact on the production process and performance of the plastic industry and people's production and life. However, the development of the entire industry is currently focused on large-scale production of general-purpose varieties, and there are few structurally innovative products.

Embodiment 1

[0038] A kind of bicyclic triazole-based amphiphilic additive that can be used as PVC heat stabilizer and antibacterial agent, the preparation method is: add 14.18 kilograms (64.5mol) sodium dichloroisocyanurate (SDIC) in reaction vessel, add 100 liters of distilled water, Stir for 30 minutes until dissolved, add 14 liters of anhydrous acetic acid to the above SDIC aqueous solution, stir for 30 minutes, dissolve 2.18 kg (16 mol) bi-1,2,4-triazole (BTz) in 20 liters of distilled water, and directly dissolve the BTz aqueous solution Added to the above solution, stirred at room temperature for 12h. The reaction solution was filtered, the filter cake was washed with distilled water at 60°C, the white solid filter cake was dissolved in acetone, and recrystallized to obtain 3.75 kg of pure product tetrachlorobis-1,2,4-triazole (TCBT). was 85.6%. m.p.: 248.6~249.2℃; 13 C NMR (DMSO-d 6 )δC: 142.68ppm; IR (KBr): 1484, 1472, 1316, 1293, 963, 664, 506cm -1 . The above-mentioned filt...

Embodiment 2

[0046] Preparation of a bicyclic triazole-based amphiphilic PVC heat stabilizer: stearic acid and 3,3',5,5'-tetrachloro-4,4'-azo-1,2,4-triazole After the chlorine atom undergoes a nucleophilic substitution reaction under specific conditions, the obtained azotriazole containing stearate group has improved its blendability with plastics compared with the raw material before the reaction, and then through complexation reaction with Zinc oxide complexation can be realized as a PVC heat stabilizer and has a certain ultraviolet absorption function.

[0047] Specifically: add stearic acid and triethylamine into the reaction vessel at a molar ratio of 3:2, stir at room temperature until the stearic acid is completely dissolved, and then add 1 / 4 of the molar amount of stearic acid 3,3' , 5,5'-tetrachloro-azo-1,2,4-triazole, heated until the system reached 80-90°C, reacted for 3 hours under reflux condensation, stopped heating, cooled to room temperature, and washed the obtained product...

Abstract

The invention belongs to the technical field of plastic production, and discloses a bicyclic triazolyl amphiphilic multifunctional plastic additive and a preparation method thereof. A bicyclotriazole skeleton is firstly derivatized, and then the bicyclotriazole-based amphiphilic multifunctional plastic additive is prepared through nucleophilic substitution, complex reaction or double decomposition reaction and the like, so that the preparation method is simple in process, high in technical content, environment-friendly, energy-saving, consumption-reducing, high in production efficiency, low in requirements on equipment and reaction conditions, and suitable for continuous large-scale production, and high popularization and application values are realized. The obtained amphiphilic additive is a novel environment-friendly multifunctional additive, has a polar end and a non-polar end in the structure, and the polarities of the two ends can be adjusted, so that the amphiphilic additive is suitable for polar materials and non-polar materials, and has a function enhancing effect on other additives in resin processing; the additive can be used as a stabilizer, a pigment, an antioxidant, an ultraviolet absorbent, a bactericide, a mildew inhibitor and the like.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to a bicyclic triazole-based amphiphilic multifunctional plastic additive and a preparation method thereof. Background technique [0002] With the advancement of polymer synthesis technology and the development of new material technology, synthetic resin materials (plastics) have become one of the most important materials in people's daily life, and are widely used in people's daily necessities.
