Stamping die rubber spring

Abstract

The invention relates to a stamping die rubber spring. The stamping die rubber spring is characterized by comprising raw rubber, a vulcanizing agent, a filling reinforcing agent, a plasticizer, an anti-aging agent and additives. In terms of relative mass parts, the dosage of the raw rubber NBR is 100 parts; the dosage of stearic acid is 5-20 parts; the dosage of peroxide is 5-20 parts; the dosage of carbon black is 5-100 parts, and the balance additives. According to the claim 1, the stamping die rubber spring is characterized in that: the plasticizer is dibutoxyethoxyethyl ester adipate, i.e. TP-95 plasticizer. With the stamping die rubber spring provided by the invention, the safety and reliability of rubber seal can be improved, the corresponding replacement cost is reduced, and the service life of parts can be greatly prolonged.

Description

[0001] technical field

[0002] The invention relates to the field of sealing materials, and in particular provides a stamping die rubber spring. Background technique

[0003] The stamping die rubber spring is easily damaged by ozone due to its unsaturation, and the poor flexibility of the molecular chain makes the ozone crack expand faster. Especially when the product is in contact with oil during use, the antiozonant added during compounding is easily extracted by the oil, resulting in a decrease in the ability to protect against ozone damage. Contents of the invention

[0004] The purpose of the present invention is to provide a stamping die rubber spring with high hardness, low compression deformation, good heat resistance and cold resistance, and good processing performance.

[0005] The invention provides a stamping die rubber spring, which is characterized in that: the stamping die rubber spring is composed of raw rubber, vulcanizing agent, filling reinforcing agen...
