Abstract
The invention provides a manufacturing process of a cattle hide fiber brake pad. The process comprises the steps that cattle hide products such as waste and old cattle hide shoes and waste and old cattle hide bags are segmented, and substances other than cattle hide are removed; bone powder is added to aramid fibers, and the mixing is conducted for five minutes; by weight, 7% of water is added into raw materials and auxiliary materials other than the aramid fibers, the bone powder and cattle hide fibers, and the mixing is conducted for five minutes; finally the cattle hide fibers are added in, and the mixing is conducted for 10 minutes; friction materials comprise, by weight, 11%-14% of cattle hide fibers, 33%-36% of sticky rice cross-linking agents, 6%-9% of hard shell powder and 6%-9% of rice-wheat straw friction powder of 20-40 meshes. According to the manufacturing process of the cattle hide fiber brake pad, the waste and old cattle hide shoes and waste and old cattle hide bags are adopted, and the segmentation, cleaning, high temperature disinfection and pulverized processing are conducted, so that the cattle hide fibers are processed out for serving as framework reinforcing materials.
Description
Technical field
The present invention relates to a kind of manufacturing process of kraft fibers brake block, belong to field of mechanical technique.
Background technique
Along with the raising day by day of people's living standard, also increasing to the demand of automobile.In recent years, the production and marketing quantity of China's automobile industry constantly increases, and China becomes an automobile production and marketing big country already.On automobile, most important safety system is exactly braking system, and all brake members are all safety members, and brake block is one of link important in whole braking system, directly has influence on the reliability of whole braking system.Existing semimetal, pottery, micro-metal brake pad friction material formulation contain mostly: copper, graphite, Steel Fibre, iron powder, antimony sulphide, phenolic resin, sulphur, pyrite, chromite, calcined petroleum coke, tyre talc, lead powder, glass putty.When motor vehicle brake, such brake block will produce dust, affect the respiratory system of human body, nervous system, blood circulation system, and harm people's is healthy.According to incompletely statistics, within 2013, China's automobile comprises passenger car, commercial car and engineering truck, total amount 1.4 hundred million, within 1 year, change 1.2 hundred million cover brake blocks according to a car to calculate, the braking car brake block demand of China is in 1.68 hundred million cover left and right, often overlap brake block average out to 1.5 kilograms, often overlap brake block in brake process, produce 1 kilogram of dust.
Therefore, existing motor vehicle are every year by the PM2.5 of discharge 1.68 hundred million kilograms.For these problems, enterprise technology personnel carry out Curve guide impeller to existing motor vehicle brake block, although have made some progress, but still Shortcomings.
Summary of the invention
The invention provides the manufacturing process of kraft fibers brake block, the above defect can be overcome.
For solving above technical problem, the invention provides following technological scheme: the manufacturing process of kraft fibers brake block, the ox-hide goods such as waste and old ox-hide footwear, waste and old ox-hide bag, carry out dividing processing, remove the material of non-ox-hide; Aramid fibre adds bone meal batch mixing 5 minutes; Weight percent meter, adds the water batch mixing 5 minutes of 7% in except aramid fibre, bone meal, other raw materials of kraft fibers and auxiliary material; Finally add kraft fibers batch mixing 10 minutes again; By weight percentage, its friction material contains kraft fibers 11%-14%, glutinous rice crosslinking agent 33%-36%, xylocarp shell powder 6%-9%, 20-40 object rice wheat straw Frication powder 6%-9%, 500 object calcium carbonate 11%-13%, aluminium oxide 2%, bone meal 20%, aramid fibre 2%-3%, potassium titanate crystal whisker 4% and other auxiliary materials; Compacting: first time cold moudling in a mold: briquetting aspect ratio hot pressing die height is high 4 centimetres; After colding pressing, the hardness of cold pressing block: shore hardness >45; First time hot pressing: die temperature controls under 150 ° of conditions, hot pressing 15 minutes, is vented 9 times; Trickle: the briquetting after first time hot pressing is carried out trickle process, every 100 grams of briquetting trickle weight are not more than 10 grams; Secondary hot pressing: die temperature controls under 150 ° of conditions, hot pressing 25 minutes, secondary hot pressing mould is lower 0.1 centimetre than first time hot pressing die height; Friction facing is beaten riveted holes.
This brake block of manufacturing process of this kraft fibers brake block that the present invention relates to adopts waste and old ox-hide footwear, waste and old ox-hide bag, is processed into kraft fibers, as skeleton reinforcing material through over-segmentation, cleaning, high-temperature sterilization, pulverizing.The aluminium oxide of bone meal, xylocarp shell powder, calcium carbonate and micro content is adopted to rub material as increasing.Adopt rice wheat straw Frication powder to be antifriction and lubriation material, this material has low friction coefficient, the shake produced when can reduce brake; When braking the high temperature produced, this material produces high loss, and make brake block formation space have the performance of acoustic board, the noise pollution produced when reducing brake, improves the travelling comfort of driver and passenger.This brake block has stronger adsorptive power and acid resistant alkali, Corrosion Protection, can prevent the oxidation of other materials in brake block and rotten, extends brake block working life.This brake block is in brake process, and the dust of generation can under natural environmental condition effect, biodegradation, and light degradation and chemical degradation, be finally degraded into carbon dioxide and water, effectively reduces the discharge of PM2.5; Sulfur dioxide in all right purifying automobile tail gas of calcium carbonate, protects environment.
