Abstract
The invention relates to a chemical sealing product, in particular to a fabrication process for a fiber-rubber diaphragm panel for an air brake valve of a railway freight car. 100 shares of nitrile rubbers, 70 shares of fillers, 5 shares of resin tackifiers B and 5 shares of curing agents are mixed uniformly with each other in mass portion so as to prepare the rubber compounds for reservation and then 1m2 of nylon cloth, 5 shares of resins and 100 shares of water are taken, and the resin is diluted into the resin solution; the nylon cloth is immersed in the resin solution for 10 minutes and then put in a stoving chest with a temperature ranging from 60 to 70 DEG C for 20 minutes and then nylon cloth is taken out to be dried naturally; the nylon cloth is cut according to the requirement for reservation and the cloth mixed and cut into blocks is vulcanized by pressurizing using a die provided with a mould capable of preventing the cloth layer from being crinkled for a certain period of time and then the mould is opened to take out the products. The invention has the advanctages that the materials are reasonably selected; the process is simple; the fiber-rubber diaphragm panel fabricated throug the process has reliable working performance, is uneasy to be cracked, and has long service life, and is in particular suitable for the 120 air brake valve of a railway freight car.
Description
(1) technical field
The present invention relates to a kind of sealing prod, especially a kind of air break valve rubber fabric film plate for railway freight car manufacture craft.
(2) background technology
Before the seventies in last century, sealing on the China railways freight car braking machine use between the metal closely cooperate and mutually abrasive action finish.Nineteen ninety, the Ministry of Railways begins to assign presss from both sides cloth lamina membranacea development task to railway freight-car with 120 air damping valve rubbers, and the lamina membranacea product adopts the natural rubber material.The relevant manufacturer production synthetic rubber of calendar year 2001 Ministry of Railways's official approval lamina membranacea product.But be the requirement that the natural rubber template or the reliability of synthetic rubber lamina membranacea all are difficult to satisfy existing goods train vehicle safe operation, break, accident such as perforation happens occasionally.
(3) summary of the invention
The object of the present invention is to provide a kind of selection reasonable, manufacture craft is simple, and products obtained therefrom-rubber folder cloth lamina membranacea reliable working performance is difficult for breaking, and a kind of air break valve rubber fabric film plate for railway freight car and the preparation technology of long service life.
Invention is achieved like this in order to achieve the above object, the present invention is made up of paracril, carbon black, tackifier resin B (R60), vulcanizing agent, nylon cloth, resin and water, according to the mass fraction: paracril 100, carbon black 70, tackifier resin B (R60) 5, vulcanizing agent 5, nylon cloth 1m
2, resin 5, water 100, its manufacture craft process be for to get paracril 100, carbon black 70, tackifier resin B (R60) 5, vulcanizing agent 5 by above-mentioned mass fraction, above four kinds of materials are mixed are prepared into the rubber unvulcanizate semi-finished product for standby; Get nylon cloth 1m by mass fraction again
2, resin 5 and water 100, water is resin furnishing resin solution, nylon cloth put into resin solution soak that to put into temperature after taking out in 10 minutes be 60-70 ℃ drying baker, takes out the nature airing after 20 minutes, it is stand-by as required cloth to be cut into work in-process; With the rubber unvulcanizate work in-process be cut into half-finished cloth and can prevent layer of cloth corrugated mould matched moulds pressurization 10～15MPa sulfuration after 20 ± 1 minutes with being added with, die sinking taking-up product gets final product at last.The invention has the advantages that selection is reasonable, preparation technology is simple, and the rubber folder cloth lamina membranacea reliable working performance with this technology is made is difficult for breaking, and long service life.Its is special to adapt at railway freight-car and uses on 120 air brake valves, is the contrast of Northwest Rubber ﹠ Plastics Institute's test-results below.
The adhesive property test (stripping strength unit K N/m) of cloth and rubber body
Contrast by above test-results, proof adds a certain amount of tackifier in sizing material have effect to cloth bonding very much, and the bonding effect that can see use tackifier resin B and nylon cloth is best, so serve as the main folder cloth lamina membranacea of manufacturing experimently with tackifier resin B and nylon cloth just.
Be the testing data of the present invention's 120 air damping valve rubbers folder cloth lamina membranacea sample below in fatigue durability test platform, cold test platform and Qiqihar low-temperature test of Sichuan braking Science and Technology Ltd.
Normal, the fatigue testing at low temperature result of folder cloth lamina membranacea

(4) specific implementation
The present invention is made up of paracril, carbon black, tackifier resin B (R60), vulcanizing agent, nylon cloth, resin and water, according to the mass fraction: paracril 100, carbon black 70, tackifier resin B (R60) 5, vulcanizing agent 5, nylon cloth 1m
2, resin 5, water 100, its manufacture craft process is for to get paracril 100, weighting agent (being carbon black) 70, tackifier resin B (being R60) 5, vulcanizing agent 5 by above-mentioned mass fraction, above four kinds of materials mixed be prepared into the rubber unvulcanizate semi-finished product for standby; Get nylon cloth 1m by mass fraction again
2, resin 5 and water 100, water is resin furnishing resin solution, nylon cloth put into resin solution soak that to put into temperature after taking out in 10 minutes be 60-70 ℃ drying baker, takes out the nature airing after 20 minutes, it is stand-by as required cloth to be cut into work in-process; With the rubber unvulcanizate work in-process be cut into half-finished cloth and can prevent layer of cloth corrugated mould matched moulds pressurization 10～15MPa sulfuration after 20 ± 1 minutes with being added with, die sinking taking-up product gets final product at last.(selecting for use difference to be added with to prevent layer of cloth corrugated mould from can produce the required various different rubber folder cloth template products of railway freight-car 120 air brake valves respectively).
