For achieving the above object, this utility model provides following technical scheme:
A kind of sealing gasket for engine, including head gasket, described head gasket includes three-layer sealed plate and double layer of metal central layer, metal core board is compounded in three-layer sealed plate by rolling after making a spurt becomes composite plate, wherein the thickness of metal core board is 0.23mm, sealing plate surface roller coating have the organosilicon coating that seals, the cylinder mouth retainer seal position of head gasket is provided with stiffening ring, stiffening ring is suppressed with ripple, the outside of stiffening ring is coated with guard ring, and the corrosion resistant plate that described guard ring adopts thickness to be 0.25 ~ 0.28mm is made；The oilhole place of head gasket is inlaid with oilhole stiffening ring, and the water hole place of head gasket is provided with water hole stiffening ring.
As further program of the utility model: described stiffening ring adopts band ripple muscle slab to make.
As this utility model further scheme: described sealing plate adopts graphite cake, makes without asbestos board or Muscovitum.
As this utility model further scheme: described metal core board adopts cold-rolled steel sheet or tin plate to make.
As this utility model further scheme: described water hole stiffening ring adopts sheet copper, tin plate or organosilicon sealant to make.
As this utility model further scheme: described oilhole stiffening ring adopts rubber seal or organosilicon sealant to make.
Compared with prior art, the beneficial effects of the utility model are: this utility model adopts the soft base nonmetallic materials of multilamellar and multiple layer metal acicular hook produced with combination engine gasket, adopt two-layer central layer metal material (cold-rolled steel sheet, tin plate) to roll with three-layer sealed material (graphite cake, without asbestos board, Muscovitum) to be composited, composite plate intensity is high, anti-engine pressure is high, and composite plate is easy fracture not；Envelope gas place is provided with stiffening ring, it is possible to increase sealability；Corrugating on stiffening ring, it is possible to increase pressure, improve sealability further；Water hole adopts sheet copper, tin plate or printing organosilicon sealant to strengthen and seals, and oilhole inlays rubber seal or printing organosilicon sealant improves sealability further.
