Abstract
A kind of metal frame foamed silastic compound seal plate is provided, there is metal frame, the upper and lower both ends of the surface of described metal frame equal compound high-low temperature resistant foamed silastic.The utility model by the thin all composite foamed silicone rubber of the upper and lower both ends of the surface of SPCC sheet metal, improves the creep properties of silicone rubber, low-intensity and varies with temperature the erratic behavior of its expansion coefficient, make the sealing material that using scope is wider.
Description
Technical field
The utility model belongs to new material technology field, is specifically related to a kind of metal frame foamed silastic compound seal plate.
Background technique
Silicone rubber material is a kind of high-low temperature resistant excellence and the composite material of low cost, pass through Material cladding, silicone rubber excellent specific property can be given full play to, simple silicone rubber is poor in intensity, but composite material has the advantages such as anti-corrosion, heat-resisting, low temperature resistant, ageing-resistant, and improve its thermal conductivity and hardness, reduce cost.The Sealing of special operation condition has been made both at home and abroad with this advanced composite material (ACM), such as high pressure, high temperature, at a high speed, high vacuum, inflammable and explosive, poisonous, strong corrosive media etc., these Sealings are widely used in petrochemical industry, chemical fertilizer, agricultural chemicals, Aeronautics and Astronautics and nuclear industry, be commonly used for the sealing of reciprocal axial motion, as the sealing of piston and piston rod, above-mentioned composite material both can be used for the occasion of dry friction oil-free lubrication, again can be unaffected to oil lubrication when conditions permit.But due to many deficiencys that silicone rubber exists when doing sealing material, as intensity, viscosity, expansion erratic behavior etc., limiting the using scope that silicone rubber is wider in Sealing, being therefore necessary to propose to improve.
Model utility content
The technical problem that the utility model solves: a kind of metal frame foamed silastic compound seal plate is provided, at the thin all composite foamed silicone rubber of the upper and lower both ends of the surface of SPCC sheet metal, by foamed silastic is compounded on steel plate, improve the creep properties of silicone rubber, low-intensity and vary with temperature the erratic behavior of its expansion coefficient, make the sealing material that using scope is wider.
The technical solution adopted in the utility model: metal frame foamed silastic compound seal plate, has metal frame, the upper and lower both ends of the surface of described metal frame equal compound high-low temperature resistant foamed silastic.
Further, described metal frame is SPCC sheet metal, and its thickness is only 0.15mm.
Further, the thickness of described high-low temperature resistant foamed silastic is 0.5mm.
The utility model advantage compared with prior art:
1, after foaming, the creep-resistant property of silicone rubber is reduced greatly, increase anti-extrudability;
2, through special process process, foamed silastic is attached on ultra-thin SPCC steel plate, and its intensity is improved greatly;
3, reduce practical set thickness, increase nominal thickness, make it have height and fill up performance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing 1, a kind of embodiment of the present utility model is described.
Metal frame foamed silastic compound seal plate, has metal frame 1, described metal frame about 1 both ends of the surface equal compound high-low temperature resistant foamed silastic 2.Described metal frame 1 is SPCC sheet metal, and its thickness is only 0.15mm, when steel plate is thicker than 0.15mm, product impact briquetting is produced and stretch, cause outward appearance out-of-flatness and assembling impact, the thickness of described high-low temperature resistant foamed silastic 2 is less than 0.3mm, and its thickness deviation is less than 0.15mm.
The utility model is by being compounded on metal frame 1 by high-low temperature resistant foamed silastic 2, thus improve the creep properties of silicone rubber, increase simultaneously its high strength and and high-foaming after assemble increase and fill up performance, make the sealing material that using scope is wider, sealing gasket after improvement is applied on rail motor set, electric locomotive or motor, and the high-low temperature resistant using scope of its application is at-50 DEG C-200 DEG C.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
Claims (2)
1. metal frame foamed silastic compound seal plate, it is characterized in that: there is metal frame (1), described metal frame (1) is both ends of the surface equal compound high-low temperature resistant foamed silastic (2) up and down, described metal frame (1) is SPCC sheet metal, and its thickness is only 0.15mm.
2. metal frame foamed silastic compound seal plate according to claim 1, is characterized in that: the thickness of described high-low temperature resistant foamed silastic (2) is less than 0.3mm, and thickness deviation is less than 0.15mm.
