Embodiment
[0036] A method for surface treatment of the ultra-high molecular weight polyethylene skeleton material used for rubber damping products of the present invention, comprising the following steps:
[0037] (1) Grinding: Mechanically grind the surface of the UHMWPE skeleton material (also the bonding surface pre-bonded with rubber) used for rubber vibration-damping products, so that the surface roughness Rz reaches 30 μm.
[0038] (2) Cleaning: Clean the bonded surface of the polished ultra-high molecular weight polyethylene skeleton material with absolute ethanol to remove surface adherents such as oil stains and dust on the surface.
[0039] (3) Plasma surface active treatment: place the cleaned ultra-high molecular weight polyethylene skeleton material in conventional plasma treatment equipment (such as jet low-temperature plasma surface treatment equipment), set the equipment speed to 200 rpm, and the distance between the nozzles to exceed The distance between the bonding sur...

Abstract
The invention discloses a surface treating method for an ultra-high molecular weight polyethylene skeleton material for rubber damping products and an application. The surface treating method comprises steps as follows: performing plasma surface activity treatment, silane coupling agent coating, baking, adhesive coating and drying on the ultra-high molecular weight polyethylene skeleton material; effective bonding of ultra-high molecular weight polyethylene and rubber is realized in a heat vulcanization manner in the application. With the adoption of the surface treating method, the bonding strength of the ultra-high molecular weight polyethylene skeleton material and the rubber can reach 30 N / mm, and the adhesive coverage can be as high as 90% or higher. The surface treating method is particularly applicable to solution of the condition of incapability of realizing high bonding strength and high adhesive coverage bonding of the ultra-high molecular weight polyethylene and the rubber.
Description
technical field [0001] The invention belongs to the field of rubber damping products, and in particular relates to a surface treatment method and application of an ultra-high molecular weight polyethylene skeleton material used for rubber damping products. Background technique [0002] The extremely high molecular weight of ultra-high molecular weight polyethylene endows it with excellent performance. It has comprehensive properties such as wear resistance, impact resistance, self-lubrication, corrosion resistance, impact energy absorption, low temperature resistance, no adhesion, no water absorption, and low density. In recent years, in the field of rail transit rubber vibration-damping products, ultra-high molecular weight polyethylene has been gradually introduced into rubber vibration-damping products as a skeleton material because of its low density and many advantages such as wear resistance. [0003] Rubber vibration-damping products usually act in an environment wher...
