Rectorite organic compound for synthesizing nano compound material and preparation method thereof

Abstract

The present invention relates to a kind of rectorite / organic monomer composite material for synthesizing nano composite material and its preparation method. Its preparation method includes the following steps: dispering the rectorite in dispersing agent, high-speed stirring to obtain mud suspension, then adding organic monomer cation exchanger or organic monomer and protonation reagent and making them produce ion exchange reaction for 0.5-8h. at room temp., and separating rectorite / organic flocculate, dehydrating, washing, drying and breaking so as to obtain the invented finished product. Said composite is a functional filler capable of producing cross-linking reaction with polymer substrate, and is suitable for synthesizing plastic or rubber polymer nano composite material.

Description

technical field

[0001] The invention relates to a rectorite / organic compound used for synthesizing nano-composite materials and its preparation method, specifically a functional filler capable of polymerizing and cross-linking with a polymer matrix, belonging to organic macromolecular compounds field. Background technique

[0002] In order to improve the mechanical strength and thermal properties of polymers such as plastics or rubber, it is often used to add modified inorganic mineral fillers to the polymer matrix, because the properties of the organic molecules on the surface of the modified mineral and the polymer phase interface are too different. Large, the binding force is relatively weak, so it is very limited to improve the performance of the polymer with fillers modified by ordinary coupling agents. In 1988, U.S. Patent No. 4,739,007 disclosed a method for preparing polyamide / clay nanocomposite materials by intercalation method. The composite materials produced hav...
