Description
Technical field
The present invention relates to technical field of rail traffic, particularly relate to a kind of system for controlling platform door opening and closing state and
Method.
Background technology
Friction material is to brake the multi-element composite material with transmission, the direct shadow of its quality for vehicle and dynamic power machine
Ring reliability and the life security of operator of machine.Friction material mainly include brake facing (being commonly called as brake block) and from
Clutch dough sheet (is commonly called as clutch disc).Brake block is used for braking, and clutch disc is used for transmission.
The brake block of organic type without asbestos, as possessing the brake block of excellent properties, is the main flow of application at present.At present without stone
The research and development of cotton organic type brake block, it is raw-material chooses, and the aspects such as formula designs, the design of Rotating fields, the improvement of technique are equal
There is technical problem.Additionally, traditional technology of preparing also limit the lifting without asbestos organic type brake block combination property.
Traditional gasket for disc brake preparation technology is as follows:
1) inspection sentenced by material: tested by physicochemical property, is evaluated used raw material.
2) raw material mixes platform: measures raw material by formula proportion and permits a point mixing, making various raw material divide as far as possible
Dissipate uniformly.Batch mixing can be divided into dry method batch mixing, semidry method batch mixing and material by wet type mixing.
3) hot-forming forming method includes one-step method and two step method, and one-step method is that mixed raw material is loaded mould,
Directly molding on hot press, mixed raw material is first prepared as preform by two step method, reinstalls hot sizing in hot pressing die.
4) post processing: after hot forming, friction material not yet assimilates completely, needs further according to the technological parameter set
Carry out post curing treatment in an oven.
5) sharp processing.
Along with the development of 3D printing technique, it is difficult to coordinate without asbestos organic type brake block combination property for high-performance, multiple
Miscellaneous structure is difficult to the defect of molding, and it is gradually overcome.
Summary of the invention
It is an object of the invention to propose a kind of 3D printing and prepare brake liner blade technolgy, it is possible to realize control property control shape one
Change and manufacture, it is thus achieved that required high-performance.
For reaching this purpose, the present invention by the following technical solutions:
Brake liner blade technolgy is prepared in a kind of 3D printing, including:
(1) batch mixing: solid fillers dry mixed is uniform, then adhesive and other additives of liquid are configured to peptization
Liquid, and solid fillers is sprayed；
(2) paving powder: the powder obtained after batch mixing is spread powder to 0.5mm thickness；
(3) glue spraying: by liquid phenolic resin, coupling agent, acetone soln and nitrile rubber powder and the reinforcing agent of plasticizer
The dry powder blend of composition is uniform, is then added to mix homogeneously in dehydrated alcohol, and adjustment colloid density is 700kg/m3, injection pressure
150kPa, carries out glue spraying；
(4) hot blast is quick-drying: be dried 100-130min under temperature 50 C；Then cut out material and be overlapped；
(5) shaped by fluid pressure: carry out shaped by fluid pressure under molding temperature 130-170 DEG C, 18-30MPa briquetting pressure, during pressurize
Between be 15-30min.
Using the brake facing that the above-mentioned technique of the present invention prepares, when 100-250 degree Celsius, its coefficient of friction is steady
Being scheduled between 0.476-0.53, heat fading is the least, has well restorative, the wearability of heat and shear resistant.
Detailed description of the invention
Technical scheme is further illustrated below by detailed description of the invention.
