Description
Technical Field
The invention is applied to the technical field of environment-friendly rubber reinforcing materials, and particularly relates to a preparation method of an environment-friendly coating additive.
Background
The attapulgite mineral has the advantages of abundant resources, easy exploitation, low price and the like, and is a water-containing magnesium-rich aluminosilicate clay mineral with a chain layered structure. In recent years, nanocomposites have been the hot spot of research in the field of materials science, and have become the most important leading research direction of composite materials due to their excellent combination of properties. The attapulgite serving as a natural one-dimensional nano material has a good reinforcing effect on polymers theoretically, and attracts extensive attention of researchers. Many researches are carried out on the nano reinforcing filler for the attapulgite-based rubber, but most researches stay in the theoretical research stage, and no report on industrialization of the rubber/attapulgite composite material is found. The reason is that the traditional processing method in the rubber industry is a mechanical mixing method, although attapulgite belongs to a layered silicate mineral, the attapulgite has a special structure, is a fiber which is rich in zeolite water, coordinated water and structural water and is internally distributed with pore channels consistent with the extension direction, has stronger polarity on the surface and can not be well compatible with the nonpolar nature of rubber, so that the attapulgite can not simply enlarge the interlayer spacing by virtue of the shearing action of macromolecular chains like montmorillonite, strip a nanoscale sheet layer, and can not easily obtain a nanocomposite material with excellent performance, the surface of the attapulgite needs to be treated, the surface polarity of the attapulgite is reduced, and the compatibility of the attapulgite and a nonpolar material is increased so as to achieve nanoscale dispersion in a matrix material; the rubber is a high-elasticity polymer material with reversible deformation, is rich in elasticity at room temperature, can generate large deformation under the action of small external force, and can recover the original shape after the external force is removed. Has good physical and mechanical properties and chemical stability. Rubber is a basic raw material in the rubber industry and is widely used for manufacturing tires, rubber tubes, adhesive tapes, cables and other various rubber products.
Considering that the industrial production scale of the attapulgite mineral can be realized by refining the purification conditions and optimizing the purification process; the problem of overhigh polarity of the attapulgite can be solved without changing the existing production equipment and process conditions of a factory, the rubber latex and the attapulgite are well compounded, and the attapulgite is uniformly dispersed in rubber to play a more effective reinforcing role.
