Embodiment Construction

[0033] Palm fiber reinforced environmentally friendly brake pads use melamine modified phenolic resin as binder, palm fiber, aramid fiber, ceramic fiber as reinforcement material, and add corundum friction material, soft foam iron powder, flake aluminum powder and Artificial granular graphite is used as a friction performance modifier to improve and enhance the friction performance of brake pads. In order to improve the production efficiency and the qualification rate of brake pads, the brake pads were prepared by a process of 2-step temperature rise, 3-time deflation, and temperature-controlled curing. The product has simple molding process, wide sources of raw materials, low cost, no harm, and good comprehensive performance. Its main performance indicators have reached the relevant national standards, and it is expected to become a new generation of asbestos-free brake pads.

[0034] The optimum formula ratio that the present invention obtains through repeated tests is:

Abstract

The invention relates to a palm fiber-reinforced environment-friendly type brake pad and a preparation method thereof. The palm fiber-reinforced environment-friendly type brake pad comprises the components of natural palm reinforced fibers taken as a material framework, ceramic fibers, melamine modified phenolic resin, a friction performance conditioning agent and a filler; the parts by weight of the components are as follows: 25-35 parts of reinforced fibers, 10-15 parts of adhesive, 8-12 parts of friction performance conditioning agent and 35-45 parts of filler. After being pretreated, the natural palm fibers have multiple good performances of being long in fibers, tenacious in texture, high in elasticity and tensile strength, wear-resistant and the like, and belong to renewable resource. Under optimal process conditions, the prepared palm fiber-reinforced brake pad can stabilize and reduce the expansion of material and improve the braking performance; the palm fiber-reinforced environment-friendly type brake pad is good in chemical stability and heat fading performance, so that the surface of the brake pad is prevented from being corroded. A great deal of gaps exist among the palm fibers, and the palm fibers are internally hollow, so that the manufactured brake pad is high in porosity, reduces the brake noise and is an ideal environment-friendly type natural fiber-reinforced material.

Description

technical field [0001] The invention relates to a brake pad for automobile braking, in particular to a palm fiber reinforced environment-friendly brake pad and a preparation method thereof. Background technique [0002] In the past 20 years, the composition and manufacturing process of brake pads for mobile machinery represented by automobiles have undergone significant changes. New brake pads have better braking performance, longer life and are more conducive to environmental protection and human health. . Traditional non-metallic brake pads are mainly asbestos brake pads, which have been gradually replaced by inorganic fibers, organic fibers and natural fibers because of their environmental pollution and poor high temperature stability. At present, in foreign countries, especially developed regions such as Europe, Japan, and the United States, non-asbestos brake pads are widely used. [0003] Reinforcing fiber is the main friction component of brake pads and plays a role...
