Embodiment 1

[0037] Preparation of KH-550 coupling agent modified attapulgite: add 150mL ethanol (80%) and 3g attapulgite to a 250mL three-necked flask, add 1.5g KH-550 dropwise, and reflux and stir at 80°C for 3h, react After completion, the product was repeatedly washed with ethanol and water, and finally dried at 110° C. for 12 hours to obtain a modified attapulgite.

[0038]Preparation of KH-550 coupling agent modified montmorillonite: Add 150mL ethanol (80%) and 3g montmorillonite into a 250mL three-necked flask, add 1.5g KH-550 dropwise and reflux and stir at 80°C for 3h, react After completion, the product was repeatedly washed with ethanol and water, and finally dried at 110° C. for 12 hours to obtain a modified attapulgite.

[0039] Preparation of multifunctional additives: mix attapulgite modified with KH-550 coupling agent and montmorillonite modified with KH-550 coupling agent at a mass ratio of 1:1 to obtain mixed clay. Add 10 g of mixed clay, 3 g of pentaerythritol diphospha...

Embodiment 2

[0059] Mix the attapulgite modified with KH-550 coupling agent and the montmorillonite modified with KH-550 coupling agent at a mass ratio of 10:1 to obtain mixed clay. Add 10g of mixed clay, 2g of pentaerythritol diphosphate diphosphoryl chloride, 0.15 of triethylamine and 100mL of dichloromethane into a three-neck flask, and heat to reflux. Cool under reflux for 6 hours, filter, extract with chloroform Soxhlet for 12 hours to wash off the pentaerythritol diphosphate diphosphoryl chloride that is not grafted to the clay surface, and then wash with distilled water until there is no chloride ion. The product is vacuum-dried to constant weight, and ball-milled to 1500 mesh for later use.

Embodiment 3

[0061] Mix the attapulgite modified with KH-550 coupling agent and the montmorillonite modified with KH-550 coupling agent at a mass ratio of 1:10 to obtain mixed clay. Add 10 g of mixed clay, 5 g of pentaerythritol diphosphate diphosphoryl chloride, 0.5 g of triethylamine and 200 mL of dichloromethane into a three-neck flask, and heat to reflux. Cool under reflux for 6 hours, filter, extract with chloroform Soxhlet for 12 hours to wash off the pentaerythritol diphosphate diphosphoryl chloride that is not grafted to the clay surface, and then wash with distilled water until there is no chloride ion. The product is vacuum-dried to constant weight, and ball-milled to 1500 mesh for later use.

Abstract

The invention discloses a multifunctional auxiliary agent for polymer materials. The multifunctional auxiliary agent is modified by silane coupling agent attapulgite, silane coupling agent modified montmorillonite and pentaerythritol bisphosphate diphosphorus wherein, the mass ratio of the silane coupling agent-modified attapulgite to the silane coupling agent-modified montmorillonite is 1:10-10:1, and the amount of the pentaerythritol bisphosphate diphosphoryl chloride is The silane coupling agent-modified attapulgite and the silane coupling agent-modified montmorillonite account for 20% to 50% of the total mass. Compared with the prior art, the multifunctional adjuvant of the present invention can significantly increase the oxygen index of the polymer material, reduce the smoke density, improve the mechanical properties, improve the carbonization, reduce the heat release rate, and reduce the oxygen consumption during combustion, and Addition is low.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a multifunctional additive for polymer materials. Background technique [0002] Polymer materials can be divided into natural polymers and synthetic polymer materials according to major categories. Since the beginning of the 20th century, synthetic polymer materials represented by plastics, rubber and fibers have entered thousands of households. The wide application of synthetic polymer materials has played a pivotal role in agriculture, energy, information, environment and industrial products. Synthetic polymer materials have the characteristics of large quantity and wide range. Polymer materials are widely used in many fields such as high-end manufacturing, electronic information, transportation, building energy saving, aerospace, national defense and military industry because of their excellent properties such as light weight, high strength, temperature resistanc...
