Abstract
The invention relates to a rubber dynamic sealing material which is prepared by the following raw materials in parts by weight: 90-100 parts of acrylic rubber, 2-5 parts of triethylenetetramine, 2-5 parts of benzoyl peroxide, 8-12 parts of zinc oxide, 8-12 parts of magnesium oxide, 40-60 parts of silica and 0.7-0.8 part of sulfur. When in preparation, plasticating is firstly carried out on raw rubber, then mixing, semi-finished extrusion, bonding, mold pressing, vulcanizing and trimming are further carried out on the raw rubber and vulcanizing agent, reinforcing agent, plasticizer, accelerator, anti-aging agent and the like, thereby preparing a finished product. The abrasion resistance of the rubber dynamic sealing material is more than 10 times of that of natural rubber, and the rubber dynamic sealing material can work under the occasions at the temperature of about 200 DEG C due to the heat resistance. In addition, the swelling ratio is lower than 15%, and the oil-resistant performance is greatly increased.
Description
Technical field
The present invention relates to a kind of sealing material, particularly a kind of rubber dynamic sealing material.
Background technology
Gu the shape dynamic sealing material mainly is a rubber-like,, just must possess following properties as solid shape dynamic sealing material: wear resistance, thermotolerance and oil-proofness because solid shape dynamic seal will be noted the harshness of the working conditions of various dynamic junctions.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed all very strong rubber dynamic sealing material of a kind of wear resistance, thermotolerance and oil-proofness.
The technical problem to be solved in the present invention is achieved through the following technical solutions, and a kind of rubber dynamic sealing material is characterized in: it is made by following materials of weight proportions,
Acrylic elastomer 90～100 triethylene tetramines 2～5
Benzoyl peroxide 2～5 zinc oxide 8～12
Magnesium oxide 8～12 white carbon blacks 40～60
Sulphur 0.7～0.8.
Earlier rubber is plasticated when the present invention prepares, mixing together with vulcanizing agent, strengthening agent, softening agent, promotor, anti-aging agent etc. again, work in-process extrude, bonding, mold pressing, sulfuration and deburring, get final product finished product.Its wear resistance is more than 10 times of natural rubber, and heat resisting temperature can be worked under the occasion about 200 ℃.Its swelling ratio has increased its oil resistance greatly below 15% in addition.
Embodiment
A kind of rubber dynamic sealing material, it is made by following materials of weight proportions,
Acrylic elastomer 90～100 triethylene tetramines 2～5
Benzoyl peroxide 2～5 zinc oxide 8～12
Magnesium oxide 8～12 white carbon blacks 40～60
Sulphur 0.7～0.8.
The optimum weight proportioning of this rubber dynamic sealing material is:
Acrylic elastomer 100 triethylene tetramines 2
Benzoyl peroxide 3 zinc oxide 10
Magnesium oxide 10 white carbon blacks 50
Sulphur 0.7.
Earlier rubber is plasticated when the present invention prepares, mixing together with vulcanizing agent, strengthening agent, softening agent, promotor, anti-aging agent etc. again, work in-process extrude, bonding, mold pressing, sulfuration and deburring, get final product finished product.
