Embodiment 1

[0011] Example 1: A quench-resistant sealing ring used in a low-temperature storage tank, characterized by being made of the following parts by weight of raw materials: 50 parts of modified cinder, 10 parts of nickel, 0.5 parts of copper, 6 parts of aluminum, 1 part of silicon , 3 parts iron, 0.05 parts chromium.

[0012] Modified cinder is made of the following raw materials by weight: 100 parts of cinder, 2 parts of polytetrafluoroethylene powder, 1 part of ammonium sulfate, 0.5 part of sodium lignosulfonate, 3 parts of epoxy resin, 1 part of diatomaceous earth, 0.5 One part sodium pyrophosphate, one part sodium carboxymethyl cellulose.

Embodiment 2

[0013] Example 2: A quench-resistant sealing ring used in a low-temperature storage tank, characterized by being made of the following parts by weight of raw materials: 60 parts of modified coal slag, 13 parts of nickel, 1 part of copper, 8 parts of aluminum, and 2 parts of silicon , 4 parts iron, 0.1 part chromium.

[0014] Modified cinder is made of the following raw materials by weight: 110 parts of cinder, 3 parts of polytetrafluoroethylene powder, 2 parts of ammonium sulfate, 1 part of sodium lignosulfonate, 4 parts of epoxy resin, 1.5 parts of diatomaceous earth, 1 part One part sodium pyrophosphate, 2 parts sodium carboxymethyl cellulose.

[0015] The modified cinder preparation method is as follows: the cinder is sintered again at 1000-1200 DEG C for 3-4 hours, and then ground into a powder form, and the remaining raw materials are added and mixed uniformly, dried, and ground into a powder form.

Abstract

The invention relates to the technical field of gaskets, in particular to a quenching-resistant sealing ring for a low-temperature storage tank. The quenching-resistant sealing ring is characterized in that the quenching-resistant sealing ring comprises, by weight, 50-60 parts of modified coal cinder, 10-13 parts of nickel, 0.5-1 part of copper, 6-8 parts of aluminum, 1-2 parts of silicon, 3-4 parts of iron and 0.05-0.1 part of chromium. The modified coal cinder is adopted in the obtained sealing ring, energy sources are saved, then other metals are added, comprehensive performance is improved, and the quenching resistance and low temperature resistance of the sealing ring are enhanced.

Description

Technical field: [0001] The present invention relates to the technical field of gaskets, and more specifically to a quench-resistant gasket used in a low-temperature storage tank. Background technique: [0002] Sealing rings generally pay attention to the following conditions: full of elasticity and resilience; appropriate mechanical strength, including expansion strength, elongation and tear strength, etc.; stable performance, not easy to swell in the medium, and small thermal shrinkage (Joule effect) ;Easy to process and shape, and can maintain precise dimensions; does not corrode the contact surface, does not pollute the medium, etc., in the low-temperature storage tank, when filling the liquid, a sealing ring is used between the metal hose and the inlet, and it is sealed under normal conditions The ring is in a normal temperature state. When the liquid is filled, the sealing ring will suddenly come into contact with a low temperature liquid of more than one hundred degrees be...
