Abstract

EVA / EPDM / CPE / MMT nano-composite closed-cell micro-cellular foam rubber-plastic combined inner tube belongs to the scientific and technological field of nano-composite foam rubber and plastic products. The method is to mix and shear the EVA nanocomposite base material and other filler additives according to the weight of the preferred formula to make EVA blended foam material, put it into the molding machine, heat it at high temperature for foaming, and then you can get high-performance Molecular EVA nano-composite rubber and plastic products. The invention solves the versatility of the combined tire inner tubes of various vehicles, airplanes and bicycles, and obtains a substantive breakthrough in new material products that are not afraid of being punctured and not inflated, high in quality and low in price, can be recycled and utilized.

Description

technical field [0001] The invention belongs to the scientific and technical field of nanocomposite foamed rubber and plastic products, and is an EVA nanocomposite closed-cell microporous foamed rubber and plastic inner tube widely used in tires for bicycles, light trucks and cars. Background technique [0002] The tires of cycling, light-duty trucks and cars are already familiar items in people's field of vision, and what can cause people's attention the most is the replacement of tire bursts and inflation of various types of tires. With the continuous advancement of science and technology, the products of the tire industry have also improved to varying degrees. For example, the solid and hollow rubber tires in the current products have the advantage of not being afraid of being punctured and not being inflated. However, these tires still cannot achieve versatility and high strength. , wear resistance and long service life requirements. We analyze and compare the functions...
