High-strength high-temperature-resistant clutch facing and method for preparing same

Abstract

The invention discloses a high-strength high-temperature-resistant clutch facing and a method for preparing the same. The high-strength high-temperature-resistant clutch facing is made from phenolic resin, preservatives, thickeners, nitrile rubber, wollastonite, inorganic silicate, inorganic phosphate, iron black, carbon black, zinc oxide, sodium chloride, aluminum oxide and distilled water. The high-strength high-temperature-resistant clutch facing and the method have the advantages that the proportions of various components of the high-strength high-temperature-resistant clutch facing are strictly controlled, the traditional clutch facing formulas are changed, accordingly, the comprehensive performance of the high-strength high-temperature-resistant clutch facing can be greatly improved,and processes for manufacturing the high-strength high-temperature-resistant clutch facing are simple; the water temperature is easy to control in water-bath heating modes, and accordingly the high-strength high-temperature-resistant clutch facing is stable in performance; styrene butadiene rubber in existing formulas is replaced by the nitrile rubber, and accordingly the high-temperature resistance of the high-strength high-temperature-resistant clutch facing can be greatly improved; framework core materials are reinforcement composite wires, each reinforcement composite wire comprises two wires and three expanded glass fibers, each wire comprises twelve 18-wire copper wires, a chemical fiber and three glass fibers which are combined with one another and are primarily twisted, and accordingly the bonding strength of framework materials and slurry can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a high-strength and high-temperature-resistant clutch facing and a preparation method thereof. Background technique [0002] The clutch face is a polymer ternary composite material, which is mainly composed of polymer binder (resin and rubber), reinforcing material, friction filler and other compounding ingredients. It is produced through a series of production and processing. products. Due to the vigorous development of the automobile industry, its requirements for the braking system are also more stringent, and the friction material must comply with the demand. On the one hand, it must meet the various performance indicators that should be achieved when the automobile is driven, and on the other hand, it must meet the safety and comfort of use. Stable, harmless to the human body, no pollution to the environment, and also have the effect of saving energy and reducing ...

Problems solved by technology

[0004] However, the above scheme still has certain defects. The combination of the skeleton core material and the slurry is not good, which makes the friction and wear performance of the clutch face product unstable, and the clutch face is easy to cause large shrinkage.
