Description

Technical Field

[0001] This utility model relates to the field of sheet technology, specifically a continuously produced plastic-metal-rubber composite sheet used to manufacture sealing gaskets, shock absorbers, and sound-absorbing sheets. Background Technology

[0002] Existing metal gaskets generally have good sealing performance and service life, but require high sealing pressure. Metal gaskets have poor elasticity and flexibility, and when subjected to vibration, impact or temperature changes, they cannot adapt through their own elastic deformation like non-metallic gaskets, which may lead to sealing gaps and thus affect the sealing performance. Non-metallic gaskets, due to their poor rigidity and durability, are difficult to use for the sealing requirements of high-performance vehicles, equipment and pipelines.

[0003] Current metal-rubber composite gaskets have rubber layers on both sides. The overall rubber layer is relatively soft and has a large surface roughness. When subjected to force, the friction will be greater. In some applications that require sliding, during assembly and relative movement with the sealing surface, a large frictional resistance will be generated, which will accelerate the wear of the sealing surface and the gasket itself, and shorten the service life of the gasket and related equipment.

[0006] Furthermore, the thickness of the metal plate is 0.3-1.2 mm.

[0007] Furthermore, the plastic layer is made of polyimide (PI), ether ether ketone (PEEK), or polyphenylene sulfide (PPS).

[0008] The beneficial effects of this utility model are:

[0009] 1. The plastic layer uses polyimide (PI), polyetheretherketone (PEEK), or polyphenylene sulfide (PPS); Polyimide (PI): possesses excellent high temperature resistance, radiation resistance, chemical corrosion resistance, as well as high mechanical strength and electrical insulation properties; Polyetheretherketone (PEEK): possesses high temperature resistance, wear resistance, corrosion resistance, and high strength; Polyphenylene sulfide (PPS): possesses excellent thermal stability, chemical stability, flame retardancy, and electrical properties;

[0010] 2. The metal plate is coated with an adhesive layer on both sides to prevent the steel plate from rusting and to increase the adhesion between the substrate and the rubber and plastic layers.

[0011] 3. Plastic and rubber are bonded to the adhesive layers on both sides of the metal plate, resulting in a lower coefficient of friction and better vibration reduction for the sound-absorbing sheet and spring clips.

[0012] 4. The resulting plastic-metal-rubber composite sheet is resistant to oil, antifreeze, and salt spray, and has excellent aging resistance.

[0013] 5. Composite panels can be produced continuously. Attached Figure Description

[0016] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.

[0017] like Figure 1 As shown, a continuously produced plastic-metal-rubber composite sheet includes a metal plate 1 with a thickness of 0.3-1.2 mm, preferably 0.4 mm; adhesive is applied to both sides of the metal plate 1 by roller coating and dried to form an adhesive layer 2; rubber slurry is then applied to one side of the adhesive layer 2 by scraping or extrusion, and after surface drying, a rubber layer 4 is formed; an anti-adhesive layer is then applied to the rubber layer 4 to form an anti-adhesive layer 5; a plastic layer is applied to the other side of the adhesive layer 2 and after surface drying, a plastic layer 3 is formed; and finally, the plastic-metal-rubber composite sheet is formed by passing it through a vulcanization oven.

[0018] The aforementioned plastic layer is made of polyimide (PI), ether ether ketone (PEEK), or polyphenylene sulfide (PPS).

[0019] Polyimide (PI): It has excellent high temperature resistance, radiation resistance, chemical corrosion resistance, as well as high mechanical strength and electrical insulation properties; it is often used in the aerospace field, such as heat insulation materials for aircraft engines and high temperature resistant components for electronic devices; in the electronics field, it is used in the manufacture of flexible circuit boards, taking advantage of its high temperature resistance and good flexibility.

[0020] Polyetheretherketone (PEEK): It has properties such as high temperature resistance, wear resistance, corrosion resistance, and high strength. In the medical field, it can be used to manufacture artificial joints, dental implants, etc. In the aerospace field, it is used to manufacture key components such as aircraft wings and landing gear.

[0024] High strength and pressure resistance: The addition of metallic materials enhances the overall strength of the sealing plate, enabling it to withstand high pressure and resist deformation and damage, making it suitable for high-pressure sealing systems;

[0025] High temperature and low temperature resistance: Plastic-metal-rubber composite sheets can maintain stable performance over a wide temperature range. They do not soften or lose elasticity at high temperatures, nor do they become brittle or crack at low temperatures.

[0026] Wear resistance: The plastic layer used on one side of the plastic-metal-rubber composite sheet has good sliding and wear resistance, which can resist friction and wear between sealing surfaces, extend service life, and reduce maintenance costs.
