A kind of universal joint high-temperature resistant coating
Technical field
The application belongs to metallic paint field, relates in particular to a kind of universal joint high-temperature resistant coating.
Background technology
So-called universal joint refers to devices such as utilizing ball-type and exports with the axle power of realizing different directions, and it is also on automobile one very vitals.Universal joint and transmission shaft combination, be called cardan gear.On the vehicle of front-mounted engine rear wheel drive, cardan gear is arranged between transmission output shaft and main reducing gear of drive axle input shaft; And the vehicle of front-mounted engine front-wheel drive has omitted transmission shaft, universal joint is arranged between not only responsible driving but also the front axle half shaft of being responsible for turning to and wheel; Between the variator and drive axle of engine behind front wheel rear wheel drive truck.When distant between variator and drive axle, transmission shaft should be divided into two sections of even multistages, and add intermediate support.Between the transfer gear of many shaft-driven automobiles and drive axle or between drive axle and drive axle.Due to the distortion of vehicle frame, can cause between two drive disk assemblies that between axis, mutual alignment changes.Be depicted as between engine and variator.Be the parts of realizing varied angle transmission of power, for changing the position of transmission axis direction, it is " joint " parts of the universal driving device of automobile driving system.Universal joint and transmission shaft combination, be called cardan gear.On the vehicle of front-mounted engine rear wheel drive, cardan gear is arranged between transmission output shaft and main reducing gear of drive axle input shaft; And the vehicle of front-mounted engine front-wheel drive has omitted transmission shaft, universal joint is arranged between not only responsible driving but also the front axle half shaft of being responsible for turning to and wheel.
Epoxy resin is the organic high molecular compound that contains two or more epoxide groups in general reference molecule, and except indivedual, their relative molecular mass is not high.The molecular structure of epoxy resin is to contain active epoxide group in molecular chain as its feature, and epoxide group can be positioned at the end, centre of molecular chain or structure circlewise.Owing to containing active epoxide group in molecular structure, make them can form with polytype solidifying agent generation crosslinking reaction insoluble, the molten cancellated superpolymer of three-dimensional that has; The classification of epoxy resin is not yet unified at present, generally according to intensity, temperature classification and property sort, the principal item of epoxy resin has 16 kinds, comprises 16 kinds, glue in all-purpose gum, structure glue, heatproof glue, low temperature resistant glue, water and for wet surface, conductive resin, optical cement, spot welding glue, epoxy resin glued membrane, foamed glue, strain gage adhesive, soft material bonded adhesives, seal gum, special gelatin, latent curing glue, civil construction glue.And universal along with humanity concept, and the formation of novel harmonious society, design a kind of universal joint high-temperature resistant coating and be very important.
