Abstract
The invention discloses a preparation method of a rubber product of a sealing element. The preparation method comprises the following steps: weighing the following raw materials in parts by weight: 35-55 parts of crude rubber, 10-16 parts of fibers, 3-6 parts of metal filings, 2-7 parts of a compounding agent, 2-4 parts of a resin adhesive, 3-7 parts of a softening agent and 5-7 parts of a catalyst, wherein when the crude rubber is plastified by an open mill, the temperature of a roller is 35-40 DEG C, and the time is about 15-20 minutes; then adding the compounding agent and the resin adhesive for mixing, rolling the compounding agent into the adhesive, fully mixing the fibers with the crude rubber when adding the fibers so as to form mixed rubber; adding metal particles, the softening agent and the catalyst into the mixed rubber, then rolling for 4-5 minutes, controlling the temperature to be 40-45 DEG C, and then rolling the mixed rubber in a rolling machine to prepare rubber sheets. Compared with a plurality of common rubber products in drawability, the rubber provided by the invention is large in thermo-plasticity, is small in shrinkage rate, is easy to roll and is unlikely adhered to a heat roller; the rolling temperature can be controlled for preparing the rubber sheets.
Description
Technical field
The invention still further relates to a kind of making method of sealing member rubber item.
Background technology
During rubber product forming, through excessive pressure compacting, it cannot be eliminated because of elastomerics force of cohesion, in moulding, during from mould, often produces extremely unsettled contraction, must be through after a period of time, and could ease up and stablize.So, at the beginning of a rubber item design, no matter formula or mould all need careful calculating to coordinate, if not, easily produce product size unstable, cause product property low.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
For addressing the above problem, the invention provides a kind of making method of sealing member rubber item of quality better.
The technical solution used in the present invention:
A making method for sealing member rubber item, comprises the following steps:
A, take each raw material by weight: rubber 35-55 part, fiber 10-16 part, scrap metal 3-6 part, Synergist S-421 95 2-7 part, Resin adhesive 2-4 part, tenderizer 3-7 part and catalyzer 5-7 part;
When b, rubber are plasticated with mill, roller temperature is 35-40 ℃, and the time is 15-20min, and then it is mixing to add Synergist S-421 95, Resin adhesive to carry out, and Synergist S-421 95 roller is entered in glue, while adding fiber, should fully be mixed into rubber unvulcanizate with rubber;
In c, rubber unvulcanizate, add roll extrusion 4-5 minute after clipped wire, tenderizer and catalyzer, control temperature 40-45 ℃, then rubber unvulcanizate is made on rolling press to film.
Described Synergist S-421 95 is paraffin, stearic acid or rosin.
Described scrap metal is steel wire bits or copper wire bits.
Described rubber is chloroprene rubber or ethylene-propylene rubber(EPR).
Described catalyzer is ink.
Advantage of the present invention is: compared with several frequently seen rubber item drawability, this rubber thermoplastic shape is large, and shrinking percentage is little, and calendering easily, is difficult for adhering to hot-rolling, should control roll extrusion temperature, to make film.
Embodiment
Following embodiment is only for the present invention is described, but can not limit protection scope of the present invention.
