Problems solved by technology

Although these gaskets can be selectively used on certain machines to meet the performance requirements of specific working environments, as mentioned above, their overall performance is affected by the density of graphite, asbestos or other non-metallic materials covered on them. and strength limitations, but cannot meet specific or higher use requirements
Therefore, high-precision gaskets used in complex working environments tend to be damaged quickly, and often need to be maintained or replaced, affecting normal production and increasing maintenance costs

Embodiment 1

[0027] A method for preparing a rubber-coated sealing and shock-absorbing and sound-absorbing material for a metal sheet 1, wherein the coating layer (A) coated on the metal sheet is composed of rubber, fillers and compounding agents, and the specific composition ratio (weight Percentage) is as follows:

[0028] Rubber 60wt%

[0029] Filler 40wt%

[0030] Addition, compounding agent 2.4wt%

[0031] Among them, the manufacturing process of the coating layer (A) is:

[0032] 1) The rubber is fluorine rubber.

[0033] According to the capacity of the open mill (open rubber mill), the actual composition of each vehicle is calculated according to the above formula ratio. Put a certain weight of fluorine rubber into the open mill for rubber breaking and rolling, and then put in various batches and fillers for mixing in sequence.

[0034] Compounding agents include accelerators, vulcanizing agents, white carbon black, plasticizers, stabilizers, smoothing agents, acid absorbents and the l...

Embodiment 2

[0042] Another method for preparing a rubber-coated sealing and damping and sound-absorbing material for a metal sheet 1, wherein the coating layer (B) coated on the metal sheet is composed of rubber, fillers and compounding agents, and the specific composition ratio ( The weight percentage) is as follows:

[0043] Rubber 70wt%

[0044] Filler 30wt%

[0045] Addition, compounding agent 2.9wt%

[0046] Among them, the manufacturing process of the coating layer (B) is:

[0047] 1) The rubber is selected from styrene-butadiene rubber, or used in combination with natural rubber or butadiene rubber.

[0048] According to the capacity of the open mixer (open rubber mixer), the actual composition of each car is calculated according to the above formula ratio.

[0049] SBR generally does not need to be masticated, but according to the characteristics of this product, a certain degree of mastication can be appropriately carried out to improve the smoothness of the product. Plastic refining...

Embodiment 3

[0058] Another method for preparing a rubber-coated sealing and shock-absorbing and sound-absorbing material for a metal sheet 1, wherein the coating layer (C) coated on the metal sheet is composed of rubber, fillers and compounding agents, and the specific composition ratio ( The weight percentage) is as follows:

[0059] Rubber 50wt%

[0060] Filler 50wt%

[0061] Addition, compounding agent 2.0wt%

[0062] Among them, the manufacturing process of the coating layer (C) is:

[0063] 1) The rubber is nitrile rubber or acrylic rubber.

[0064] According to the capacity of the open mill, the actual component dosage of each car is calculated according to the above formula ratio.

[0065] Put the calculated certain weight of nitrile rubber into the open mill for mastication. Nitrile rubber usually needs to be masticated. Nitrile rubber has high toughness and low plasticizing effect, so a low-roller temperature, small-roller distance, and low-volume plasticizing process is required. Th...

Abstract

The present invention is sealing, damping and silencing material comprising metal sheet and coating. The coating consists of rubber, stuffing and compound ingredient. The compound ingredient includes sulfur, zinc oxide, stabilizer, etc.; the rubber is one or two selected from fluororubber, NBR, SBR, etc.; and the stuffing may be graphite, carbon black, kaolin, etc. The sealing, damping and silencing material may be machined into sealing washer in required shape, can resist the corrosion of various gas and liquid medium, operate in the temperature up to 400 deg.c and pressure up to 120 kg/sq cm, and possesses reliable sealing.

Description

Technical field [0001] The invention relates to a "rubber-metal" material, in particular to a sealing, shock-absorbing and sound-absorbing material coated with rubber on a metal sheet and a preparation method thereof. Background technique [0002] Various seals or gaskets are widely used in power machinery such as engines and refrigerators, fluid control and driving devices such as pumps and valves, and petrochemical equipment. Because these sealing materials are installed in different working environments and occasions, they must have the required mechanical, physical, chemical and other comprehensive properties to ensure the reliability and long service life of the seal. For example, mechanical parts need to work under oil resistance, acid resistance, alkali resistance, high temperature resistance, high pressure resistance or low temperature resistance. The sealing material should adapt to the above working environment and maintain good mechanical performance and safe and relia...
