Abstract
The invention discloses a coating for a universal node. The coating is prepared from the following components in parts by weight: 100 parts of epoxy resin, 14-16 parts of melamine, 20-30 parts of zinc powder, 10-15 parts of aluminum powder, 8-10 parts of dimethylformamide, 1-2 parts of carbon black, 25-35 parts of glycol ether, 10-12 parts of modifier, 8-10 parts of acetone and 1-1.5 parts of talcum powder. The surface drying time of the coating product is 2-3h and the solid drying time is 10-15h; and the coating resists the high temperature of 371 DEG C for 5 days, resists salt mist for 500h, resists acid and alkali, is high in the impact strength, is long in the service life, can be widely produced and can be used for continuously replacing the existing materials.
Description
Technical field
The application belongs to metallic paint field, relates in particular to a kind of universal joint 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.The structure of universal joint and effect are a little as the joint in human limb, and the angle between the part that it allows to be connected changes within the specific limits.The angle causing for the bob that meets transmission of power, adapts to produce while turning to automobilism changes, the drive axle of front drive automobile, and between semiaxis and wheel shaft, conventional universal joint is connected.But owing to being subject to the restriction of axial dimension, require drift angle larger again, the instantaneous angular velocity that single universal joint can not make output shaft and axle enter axle equates, easily cause vibration, the damage of aggravation parts, and produce very large noise, so extensively adopt constant velocity cardan joint miscellaneous.On front drive automobile, two constant velocity cardan joints for each semiaxis, are inboard universal joints near the universal joint of transaxle, and near axletree is outboard universal joint.On rear-drive automobile, engine, clutch coupling and variator are as a complete installation on vehicle frame, and drive axle is connected with vehicle frame by resilient suspension, has a distance between the two, need to connect.In automobilism, Uneven road produces and beats, the potential difference of load variations or two assembly installations etc., capital changes angle and the distance between transmission output shaft and main reducing gear of drive axle input shaft, therefore all adopt double Hooke's joint at the universal joint type of belt drive of rear-drive automobile, be exactly that transmission shaft two ends respectively have a universal joint, its effect is that the angle at transmission shaft two ends is equated, thereby guarantees that output shaft equates all the time with the instantaneous angular velocity of input shaft.
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 epoxy resin of domestic actual production only has several trades mark of bisphenol A-type.According to statistics, within 1997, national epoxy resin demand is about 110kt, and turnout is about 30kt, and import volume is about 60kt.The production kind trade mark of domestic epoxy is very single, is mainly bisphenol A-type.Due to domestic epoxy inferior quality, manyly require the high occasion must the external high-quality epoxy of import, as high-quality liquid epoxy, brominated epoxy, phenolic aldehyde epoxy etc.And universal along with humanity concept, and the formation of novel harmonious society, design a kind of universal joint coating and be very important.
