Problems solved by technology

[0002] Some inorganic substances are usually introduced into the current polymer materials to act as fillers or as reinforcing agents (such as glass fiber, clay, or carbon black, etc.), the purpose of which is to reduce costs and reinforce the physical properties of the original polymer substrate. properties or strength to form a composite material, however, the properties of the composite material are still limited by the dispersion of such inorganic mater

Embodiment Construction

[0021] In a specific embodiment of the present invention, the modification preparation method of the lipophilic functional group modified clay is:

[0022] Take the inorganic layered montmorillonite PK-805 produced by Baikang Nano Technology Co., Ltd., with a cation exchange equivalent of 98meq / 100g, add water and stir for 10-12 hours, and configure it as a suspension solution of 25-40% by weight to make the clay swell Moisten; take cetyltrimethylammonium bromide, about 40-50% by weight relative to the inorganic layered montmorillonite PK-805, dissolve it into an aqueous solution, and slowly drop into the aforementioned inorganic layered montmorillonite PK-805 805 suspension solution and stirred overnight; after stirring, filter the precipitate; wash the precipitate repeatedly with distilled water and then dry it at 80°C; grind the dried precipitate with a ball mill until the particle size of the powder is about 10 -6m, namely, the lipophilic functional group-modified clay of ...

Abstract

Said invention relates to a kind of lipophilic modified clay, nano ABS compounded material composed of same and preparation thereof. Said clay has layered structure, water-proof, self-cleaning function and strengthened intension and can be moulded into products with self-cleaning and water-proof function.

Description

technical field [0001] The present invention obtains an ABS nanocomposite material by mixing ABS resin with lipophilic modified clay, and the inorganic layered clay is modified by lipophilic functional groups, which can improve the compatibility with the organic ABS polymer mixing process, and The modified clay can be used to open the gap between the layered clay layer and the layer to facilitate the integration of the ABS polymer particle material, and then fully mix the ABS polymer material with the modified clay by a melting intercalation technology. refining. The technology does not need to use a solvent, can reduce the cost of a large amount of solvent materials and reduce the consideration of environmental protection factors, and obtain the nano-ABS composite material of the present invention. The nano-ABS composite material of the invention has self-cleaning properties, can improve mechanical strength, has thermal stability, can be prepared in mass production, and redu...
