Embodiment 1

[0034] Embodiment 1: Preparation of attapulgite and natural rubber nanocomposite

[0035] (1) sample

[0036] The attapulgite raw ore is produced in Xuyi, Jiangsu, and the attapulgite purified sample is self-made from the attapulgite raw ore. Figure 1 is the XRD pattern of the attapulgite purified sample. The strongest diffraction peak at d1.03779 nanometers in Figure 1 is the strongest characteristic diffraction peak of attapulgite, and the other diffraction peaks are very weak, indicating that the main phase in the purified sample is attapulgite.

Abstract

The invention discloses a making method of concave-convex bar-stone and natural rubber nanometer composite material, which comprises the following steps: dispersing through ultraviolet; modifying; blending; conglutinating; thinning; washing; dehydrating; melting; sulfurizing. The invention disperses nanometer crystal of concave-convex bar-stone in the natural rubber base, which improves rubber property.

Description

technical field [0001] The invention relates to the preparation technology of mineral and polymer-based nanocomposite materials, in particular to a method for preparing attapulgite and natural rubber nanocomposite materials by ultrasonic dispersion, surface modification, emulsion blending and coagulation and other processes. Background technique [0002] Attapulgite is a hydrous magnesium-aluminum silicate mineral with a unique structure. A single crystal particle has a one-dimensional nanometer scale. It is a natural one-dimensional nanomaterial with many excellent properties. King, the all-purpose earth". The unique nano-grain structure of attapulgite determines that it is an ideal mineral resource for preparing polymer nanocomposites. [0003] However, attapulgite nano-grains are easy to agglomerate under normal conditions, resulting in that attapulgite and polymers cannot be dispersed well after being combined, and the nano-material effect of attapulgite grains cannot b...
