Embodiment Construction

[0034] Safflower fiber reinforced environment-friendly friction material adopts high temperature resistant polyimide modified epoxy resin as binder, three kinds of fibers as hemp fiber, high-strength high-modulus polyethylene fiber and basalt fiber are used as hybrid reinforcement fibers, and corundum is added Friction-increasing materials, copper powder, and artificial graphite are used as friction performance regulators to improve and enhance the friction performance of friction materials. In order to improve the production efficiency and the qualification rate of friction materials, the friction materials were prepared by a process of 2-step heating, 3-time degassing, and temperature-controlled curing. The product has simple molding process, good physical and mechanical properties, small attenuation of friction coefficient with temperature rise, good comprehensive performance, safe and effective braking, comfortable and stable ride, and meets the humanized design requirement...

Abstract

The invention discloses an agave americana fiber-reinforced environment-friendly friction material and a preparation method thereof. The agave americana fiber-reinforced environment-friendly friction material comprises agave americana fiber serving as a material skeleton, high-strength high-modulus polyethylene fiber, basalt fiber, a friction property modifier coupling agent and filler; the content of the components is as follows: 20-30 parts of reinforcing fiber, 9-16 parts of adhesive, 8-14 parts of friction property modifier and 40-50 parts of filler. The agave americana fiber after the joint pretreatment by ultrasonic and chemical methods has multiple good properties such as good heat resistance, high decomposition temperature, relatively long fiber, relatively low fineness irregularity, relatively high elongation at break and the like. Through microfiber treatment, the interface structure between the fiber and polymer can be improved, and the mechanical properties of the fiber-reinforced polymer are enhanced. The prepared agave americana fiber-reinforced friction material has good chemical stability, good heat fading property and relatively high friction stability and is environment-friendly, thereby being an environment-friendly friction material.

Description

technical field [0001] The invention relates to a friction material for automobile braking, in particular to a spinaf fiber-reinforced environment-friendly friction material and a preparation method thereof. Background technique [0002] Friction material is a multi-component composite material, which is mainly made of three major components: reinforcing fiber, binder (resin and rubber) and friction performance modifier, and other fillers through a series of manufacturing processes. Its products are not only To have a certain good friction coefficient and wear resistance, but also have a certain heat resistance and mechanical strength. [0003] With the important changes in the production, technology and market conditions of the brake friction material industry at home and abroad, the brake material is facing a severe situation, and its performance requirements are getting higher and higher: it must have a sufficient and stable friction coefficient; The difference between t...
