Abstract
The utility model discloses a flake graphite composite sealing sheet which is composed of base material (1) and an ultrathin metal sheet (2) with small holes (3) and is characterized in that the base material (1) is composed of flake graphite, rubber and assistant mixture. The utility model has the advantages of good integral structure, strong spring back, high temperature resistance and low cost and overcomes the defects in an existing graphite packing of low strength and high cost, being widely used for sealing an automobile cylinder.
Description
The utility model discloses a kind of crystalline flake graphite that adopts is the compound seal sheet material of base-material, belongs to automobile sealed material technology field.
Traditional steam packing material has asbestos composite metal plate, Expanded graphite composite metal plate.All there is certain defective in these several sealing materials: the asbestos composite metal plate, its production technology is to adopt the indirect complex method of secondary, promptly at first adopt to copy and follow the example of the asbestos slate of producing required thickness, super thin metal with the spurt perforation is composited then, thereby asbestos separate easily with metal, have influenced quality of product and working life; The Expanded graphite composite metal plate has utilized the resistant to elevated temperatures characteristic of graphite, be used for the cylinder liner sealing material, be that other materials is incomparable, and the characteristics of graphite granule good fluidity have been utilized, can be directly and sheet metal be composited, but still have some deadly defects: the one, mechanical strength is low; The 2nd, easily sticking cylinder body, not reproducible use; The 3rd, because the Expanded graphite cost is higher, cause the product cost height, be not widely adopted so far.
It is the expensive low crystalline flake graphite compound seal sheet material of mechanical strength of main raw material with the crystalline flake graphite that goal of the invention of the present utility model provides a kind of.
The technical solution of the utility model is to adopt the mixture of crystalline flake graphite, rubber and auxiliary agent as base-material and the compound formation of super thin metal plate.
The utility model is to constitute like this: a kind of crystalline flake graphite compound seal sheet material, super thin metal plate (2) formation by base-material (1) and band aperture (3) is characterized in that base-material (1) is made of crystalline flake graphite, rubber and agent mixture.
Manufacture method of the present utility model is base material to be mixed add roll-forming behind the sheet metal in the middle of the back.
The utility model is compared with background technique, and its useful effect is:
Overall structure is good, the rebound elasticity height, high temperature resistant, oil absorbency is low, under 300 ℃ of high temperature, does not have significant rational the variation.Than asbestos composite board life-span raising 5-6 doubly, eliminated the asbestos pollution on the environment, than Expanded graphite composite board life-span raising 3-4 doubly, cost reduces about 30%.Can be widely used on the automobile as the cylinder sealing gasket.
Figure of description 1 is a structure cutaway view of the present utility model.Among the figure: (1) is base-material, and (2) are the super thin metal plate, and (3) are aperture.
Among the embodiment of the present utility model: quality is 10 o'clock than crystalline flake graphite in the base-material, and rubber is 2-3, and auxiliary agent is 0.5-1.
Claims (2)
1, a kind of crystalline flake graphite compound seal sheet material, super thin metal plate (2) formation by base-material (1) and band aperture (3) is characterized in that base-material (1) is made of crystalline flake graphite, rubber and agent mixture.
2, according to the described crystalline flake graphite compound seal of claim 1 sheet material, it is characterized in that the quality in the base-material (1) is than crystalline flake graphite at 10 o'clock, rubber is 2-3, auxiliary agent is 0.5-1.
