Abstract
The invention relates to a method used for preparing car brake disc in the field of friction material, which uses resin, fibre, grinding aid, antifriction agent, friction regular and filling agent and comprises the process steps as follows: compounding, mixing, cooling, grinding and checking. During the compounding process, according to the parts by weight, various raw materials comprise 5-15 parts of xylene arene modified resin, 2-10 parts of aramid short fibre, 10-20 parts of ceramic fibre, 5-15 parts of copper fibre, 4-6 parts of zircon, 1-3 parts of iron oxide black, 1-10 parts of graphite, 3-10 parts of friction powders, 20-30 parts of barium sulphate, 15-25 parts of potassium titanate and 2-4 parts of tyre powders. The brake disc prepared by the technical method of the invention is detected by the LINK3900 frame TP2044 standard of America, can brake with full load under the speed of 160km/h and the friction coefficient stable at more than 0.3; the car friction disc greatly improves the safety performance. Furthermore, the technique of the invention requires no modification of the existing processing technology and greatly saves the production and reconstruction cost.
Description
Technical field
The present invention relates to utilization in the friction material field prepares brake pad of car to hexichol aromatic hydrocarbon modified resin method.
Background technology
Generally include following component in the brake block preparation process: resin, fiber, increase grinding agent, anti-friction composition, friction modifier, filler.Its processing technology mainly comprises batching-batch mixing-cold mould-sulfuration-grinding-check-packing.Because the brake block of car uses under fast state usually, this just requires brake block to have the good heat-resistance characteristic, and resin is to influence the resistant to elevated temperatures principal element of brake block, occurred thus such as butyronitrile rubber modification, alternative phenolic resins such as cashew nut oil modified, organic-silicon-modified, tung oil-modified, in the hope of reaching the resistant to elevated temperatures operating characteristic of high speed.But the coefficient of friction that the brake pad of car of these production of resins is braked under 160 kilometers/hour full load situations can reach 0.2-0.25, though raising is arranged, still be difficult to satisfy instructions for use.
Summary of the invention
Purpose of the present invention is exactly at the existing defective of existing brake pad of car, and the utilization that provides a kind of high-speed and high-temperature braking quality to be improved significantly prepares the method for brake pad of car to hexichol aromatic hydrocarbon modified resin.
To achieve these goals, the present invention furthers investigate and contrast test around the following aspects emphatically: the one, and the selection of fire resistant resin material and application; The 2nd, fiber, the selection that increases grinding agent and filler material and application; The 3rd, carry out combinatory analysis and test contrast around all material proportion scale; The 4th, the reasonable coupling of new material and existing technology etc.Following technical scheme is proposed on this basis:
Utilization prepares the method for brake pad of car to hexichol aromatic hydrocarbon modified resin, be with resin, fiber, increase grinding agent, anti-friction composition, friction modifier and filler make by following processing step, batching-batch mixing-cold mould-sulfuration-grinding-check, anti-friction composition wherein is that graphite rubs, wiping conditioning agent is the friction powder, and described resin adopts paraxylene aromatic hydrocarbon modified resin, and fiber adopts aramid fiber short fibre and ceramic fibre, the copper fiber is mixed, increasing grinding agent adopts zircon and iron oxide black to be mixed, filler adopts barium sulfate and potassium titanate, tyre talc is mixed, and various raw-material weight portions are respectively in the blending process, dimethylbenzene aromatic hydrocarbon modified resin 5-15, aramid fiber short fibre 2-10, ceramic fibre 10-20, copper fiber 5-15, zircon 4-6, iron black 1-3, graphite 1-10, friction powder 3-10, barium sulfate 20-30, potassium titanate 15-25, tyre talc 2-4.
Various raw-material optimum weight part proportionings are in the blending process, dimethylbenzene aromatic hydrocarbon modified resin 8, aramid fiber short fibre 3, ceramic fibre 15, copper fiber 10, zircon 5, iron oxide black 2, graphite 8, friction powder 4, barium sulfate 25, potassium titanate 17, tyre talc 3.
Adopt the brake block of technical method preparation of the present invention, through U.S. LINK3900 stand TP2044 standard detection, the braking of 160 kilometers/hour full loads, stable friction factor is in that (under the same means of testing, the coefficient of friction that ordinary resin is filled a prescription is between 0.2-0.25 0.3 or more.), this brake pad of car security performance improves greatly.This technology does not need existing processing technology is improved in addition, has saved the production and transformation cost greatly.
The specific embodiment
Embodiment 1, and various raw-material weight portions are respectively in the blending process, dimethylbenzene aromatic hydrocarbon modified resin 10, aramid fiber short fibre 5, ceramic fibre 10, copper fiber 5, zircon 4, iron oxide black 2, graphite 5, friction powder 3, barium sulfate 20, potassium titanate 15, tyre talc 2.Above-mentioned raw materials is carried out batch mixing-cold mould-sulfuration-grinding-check on existing machining production line, final packaging promptly gets the brake pad of car finished product.
