Abstract
The invention relates to a formula of a low-temperature resistant silicone rubber seal ring. The formula comprises the following components in percentage by mass: 75% to 86% of low-phenyl silicone rubber, 4% to 7% of t-butyl perbenzoate, 2% to 6% of silicon dioxide, 5% to 10% of quartz powder and 2% to 6% of diphenyl silanediol. The formula disclosed by the invention has the following advantages that the proportion is reasonable, the property is stable, the cost is low, the molding quality of the seal ring can be guaranteed, and the like, and therefore the production benefit of a factory is increased.
Description
Technical field
The present invention relates to specialty elastomer material technology field, is a kind of formula of low temperature resistant silicone rubber O-ring specifically.
Background technology
The circular cowling that rubber seal is comprised of one or several part, be fixed on lasso of bearing or packing ring and contact or form narrow labyrinth clearance with another lasso or packing ring, prevents that lubricating oil from spilling and foreign object is invaded.That sealing-ring is mainly used in is grease proofing, waterproof, anticorrosion etc.Sealing-ring has O RunddichtringO, V-shaped seal ring, YX RunddichtringO and YX type hole back-up ring for hole on the whole.General rubber seal normal working temperature is between subzero 20 to 160 degrees centigrade, and still more and more, to particularization, diversified future development, traditional sealing-ring no longer can meet modern industrial requirements to present engineer operation environment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of reasonable ratio, stable performance, with low cost, can guarantee the formula of sealing-ring Forming Quality, i.e. a kind of formula of low temperature resistant silicone rubber O-ring.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of formula of low temperature resistant silicone rubber O-ring, this formula comprises low-phenyl silicone rubber, t-butylperoxyl benzoate, silicon-dioxide, silica powder, Diphenylsilanediol, the shared mass percent of described each component is as follows:
The shared best in quality per-cent of described each component is as follows:
The performance of described each component and effect are as follows:
Trifluoropropyl siloxane: the rubber as silica gel product is used, and high and low temperature resistance is good.
Benzoyl peroxide: vulcanizing agent, vulcanizing agent is generally at room temperature more stable, but can decompose rapidly the generation free radical under higher curing temperature, thus it is crosslinked that silicon rubber is produced.
Silicon-dioxide: the main raw of the reinforcing filler of silicon rubber claims again white carbon black.Silicon-dioxide can be divided into thermal silica and precipitated silica.Fumed silica is one of the most frequently used strengthening agent of silicon rubber,, good electrical property high by the physical strength of its cross-linked rubber of sizing material of its reinforcement, and can with other strengthening agent or weak strengthening agent use, prepare the sizing material of different service requirementss.
Silica powder: weak reinforcing filler, they generally do not use separately in silicon rubber, but with silicon-dioxide use, to regulate the hardness of silicon rubber, improve the processing performance of sizing material and oil resistance and the solvent resistance of cross-linked rubber, reduce the cost of sizing material.
Diphenylsilanediol: constitution controller, meeting hardening in the silicone rubber compounds storage process of employing fumed silica reinforcement, plasticity value descends, and loses gradually process industrial art performance, and this phenomenon is called " structurizing " effect.For preventing and weaken that the Synergist S-421 95 that this " structurizing " tendency adds is called " constitution controller ".
The invention has the beneficial effects as follows: the present invention has reasonable ratio, stable performance, with low cost, can guarantee the advantages such as sealing-ring Forming Quality, has improved the productivity effect of factory.
