Abstract

The invention relates to preparation method of rubber / halloysite nanotube nano-composite material, the invention adopts the preparation method that the rubber, the halloysite nanotube and modifying agent are mixed according to the mass ratio of 100:5 to 100 : 0.5-20 through the ordinary rubber pugging equipment and technique, then the sulphation is performed through the ordinary sulphidizing process and equipment to realize the in-situ modification, and finally, the rubber / halloysite nanotube nano-composite material with nano-dispersion, good interfacial bonding and good performance. Wherein, the modifying agent comprises compound in-situ generated phenolic resin, alkyl phenolic resin, modified rubber, methacrylic acid metal salt and one or more than one mixture (s) in the sulfur-containing organosilane coupling agent. The preparation method of rubber / halloysite nanotube nano-composite material has the advantages that the defects that the rubber / halloysite nanotube nano-composite material is difficult to be dispersed, the interfacial bonding is not good, the performance can not be improved observably can be overcome, and the preparation method can be applied in a variety of rubber products, rubber toughening plastics and binding agents and the like.

Description

(1) Technical field

[0001] The invention relates to the technical field of nanocomposite materials, in particular to a method for preparing rubber and / or halloysite nanotube nanocomposite materials. (2) Background technology

[0002] Reinforcing fillers are the largest non-rubber components in vulcanized rubber. At present, the reinforcing filler for rubber is still mainly carbon black. In recent years, the carbon black industry is facing the problem of shortage of raw material oil sources and skyrocketing prices. At the same time, the development of high-performance rubber products such as green tires has put forward many new requirements for reinforcing fillers. Therefore, the research and development of non-carbon black reinforcing fillers has become the current An important development direction of the rubber industry.

[0003] Since the end of the 20th century, some inorganic nanomaterials, such as montmorillonite, nano-calcium carbonate, nano-silica, carbon nanotubes...
