[0025] (1) The preparation process of attapulgite-based polymer additives is as follows:

[0026] Activation of attapulgite: Add attapulgite powder into 10wt% sodium hydroxide solution, prepare a slurry with a concentration of 15wt%~35wt%, stir and react at 80~100°C for 5~10h, then centrifuge and wash until Neutral, dry at 100-150°C for 5 hours, and crush to more than 2000 mesh.

[0027] Modification: add activated attapulgite powder into absolute ethanol, control the mass concentration at 15% to 35%, and add dibutyltin diacetate with a mass fraction of attapulgite powder of 1 to 20%, 60 to Stir the reaction at 100°C for 1-5 hours, and then centrifuge.

[0028] Purification: Soxhlet extraction of the centrifuged product with acetone, dichloromethane, and chloroform for 10-15 hours, and finally vacuum-drying at 100-120°C for 10-15 hours, airflow crushing to more than 2500 mesh to obtain attapulgite Additives for polymer-based materials.

Embodiment 1

[0038] Add attapulgite powder into 10wt% sodium hydroxide solution, prepare a slurry with a concentration of 15wt%, stir and react at 80°C for 10h, then centrifugally wash until neutral, dry at 100-150°C for 5h, and pulverize To more than 2000 mesh. The powder was added to absolute ethanol, the mass concentration was controlled at 15% to 35%, and dibutyltin diacetate with a mass fraction of attapulgite powder of 1% was added, stirred and reacted at 60°C for 5 h, and then centrifuged. The centrifuged product is sequentially extracted with acetone, dichloromethane, and chloroform for 10-15 hours, and finally vacuum-dried at 100-120°C for 10-15 hours, and air-jet crushed to a size above 2500 mesh to obtain attapulgite-based high Additives for molecular materials.

Embodiment 2

[0040] Add attapulgite powder into 10wt% sodium hydroxide solution, prepare a slurry with a concentration of 20wt%, stir and react at 90°C for 8h, then centrifugally wash until neutral, dry at 100-150°C for 5h, and pulverize To more than 2000 mesh. The powder was added to absolute ethanol, the mass concentration was controlled at 15% to 35%, and dibutyltin diacetate with a mass fraction of attapulgite powder of 5% was added, stirred and reacted at 70°C for 4 h, and then centrifuged. The centrifuged product is sequentially extracted with acetone, dichloromethane, and chloroform for 10-15 hours, and finally vacuum-dried at 100-120°C for 10-15 hours, and air-jet crushed to a size above 2500 mesh to obtain attapulgite-based high Additives for molecular materials.

Abstract

The invention discloses an attapulgite-based polymer material additive. The attapulgite-based polymer material additive is attapulgite which is chemically grafted with dibutyltin diacetate on the surface. The attapulgite-based polymer material additive can be obtained by enabling attapulgite to react with the dibutyltin diacetate in an organic solvent at 60-100 DEG C. The attapulgite-based polymermaterial additive can significantly improve the crusting property of polymer materials, has the macro performance of flame retardancy, reduces flue gas emission, reduces toxicity during combustion, increases carbon residual rate after combustion, and can be used for preparing flame-retardant polymer materials such as a halogen-free low-smoke flame-retardant cable material.

Description

technical field [0001] The invention belongs to the field of flame-retardant materials, and in particular relates to an attapulgite-based polymer material additive, a preparation method thereof, and an application in preparing flame-retardant polymer materials. Background technique [0002] With the development of science and technology, more and more polymer materials have entered people's lives, especially the wide application of synthetic polymers such as rubber, plastics, and fibers, which has brought unprecedented prosperity to the history of human material applications. "Plastic Age" makes people feel the blessings brought to us by colorful polymer materials, but also makes people suffer from the threat of fire caused by it. According to US statistics, building fires occur every 60s, residential fires occur every 82s, and traffic fires occur every 85s; outdoor fires are even more frequent, occurring once every 34s. The national average fire frequency is once every 17s...
