Abstract
The invention discloses an anti-cracking coating for a universal joint. The anti-cracking coating comprises the following components in parts by weight: 100 parts by weight of epoxy resin, 10-15 parts by weight of adipic acid, 5-10 parts by weight of m-phthalic acid, 2-6 parts by weight of curing agent, 10-12 parts by weight of neopentyl glycol, 1-1.5 parts by weight of methylimidazole, 10-15 parts by weight of trimethylolpropane, 50-60 parts by weight of superfine silica powder, 20-25 parts by weight of titanium dioxide and 5-10 parts by weight of butadiene styrene rubber. The surface drying time of a product is 3-4 hours, and the hard drying time of the product is 20-22 hours; the fragmentation surface is 2 mm<2> after being soaked in saline water for 72 hours, the corrosion degree is 0.1 and the anti-cracking coating resists high temperature and cold. The anti-cracking coating is anti-cracking, is high in impact strength and long in service life, and can be widely produced and used for continuously replacing an existing material.
Description
Technical field
The application belongs to metallic paint field, relates in particular to a kind of universal joint cracking resistance 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.Knuckle centre maintenance will be ground gear oil, and because the grease fitting of knuckle centre needle bearing is a common grease nipple, so cause a kind of illusion to people, the butter of generally annotating for a long time lubricates.And in fact, be to be difficult to butter filler, to needle bearing, even reach joint spider shaft neck end face also very difficult from this grease nipple.Can cause large quantities of cross shaft needle bearing earlier period damages with butter (being quicklime grease) is lubricated.
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; China started epoxy resin to be studied from 1958, and drop into industrial production with very fast speed, so far flourish throughout the country, except producing common dihydroxyphenyl propane-epoxy chloropropane type epoxy resin, also produce various types of neo-epoxy resins, to meet the urgent need of national defense construction and national economy all departments.And universal along with humanity concept, and the formation of novel harmonious society, design a kind of universal joint cracking resistance coating and be very important.
Summary of the invention
