Description

technical field [0001] The invention belongs to the technical field of polymer molding, and in particular relates to a high-hardness, low-compression deformation rubber nanocomposite material and a preparation method thereof. Background technique [0002] Rubber has the characteristics of high elasticity, low modulus, low glass transition temperature, high wear resistance, low density and can be filled in large quantities, and is widely used in various fields of the national economy. Rubber compounds can be processed into various types of products through different processing methods. The rubber material can be vulcanized into various molded products with the help of hot presses and molds, such as sealing rings, leather cups, shock-absorbing pads, etc.; hoses and profiles of different diameters can be extruded through an extruder. [0003] Rubber extrusion is a process in which the rubber material passes through the action between the extruder barrel wall and the screw to c...
