Abstract

The invention discloses an anti-aging rubber sealing ring material and a preparation method thereof. The anti-aging rubber sealing ring material is prepared from the following raw materials in parts by mass: 80-90 parts of fluorinated silicone rubber, 15-20 parts of acrylic rubber, 10-15 parts of chloroprene rubber, 10-15 parts of polyurethane rubber, 8-12 parts of polycaprolactone, 12-20 parts ofa filler, 5-8 parts of nano silica, 6-10 parts of a quartz fiber, 3-8 parts of a composite anti-aging agent and 2-5 parts of a vulcanizing agent. The preparation method of the anti-aging rubber sealing ring material comprises the following steps: weighing the raw materials, pretreating the raw materials, preparing a premix, preparing blended rubber, carrying out vulcanization molding, and carrying out trimming treatment. Due to addition of the environmental-friendly polycaprolactone in a sealing ring made of the anti-aging rubber sealing ring material, the polycaprolactone is cross-linked with the polyurethane rubber to form a dense net structure, and in addition, the material has a certain self repairing function; meanwhile, due to addition of the nano silica and the quartz fiber, the pressure resistance and the aging resistance of the sealing ring material are improved, and the service life of the sealing ring can be prolonged.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to an anti-aging rubber sealing ring material and a preparation method thereof. Background technique [0002] The sealing ring is a material or part that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents impurities such as external dust or water from intruding into the internal parts of the machine equipment. The sealing ring generally works under certain pressure and temperature conditions. Sealing rings with different structures and materials have different sealing effects under different conditions. However, once the sealing ring fails, it will directly affect the use of the equipment. At present, due to the poor aging resistance of the rubber sealing ring, the service life of the sealing ring will be shortened. At the same time, the aging sealing ring will bond with the metal, the mechanical properties will deteriorate, and the therma...
