Abstract
The invention belongs to hollow rubber pad technical field, disclose a kind of hollow rubber pad and preparation method thereof.Its technical characteristics is: in the cavity of described rubber cushion body joint, be provided with support tube, in process of production, film stock is left all the time in body two ends, when tube length reaches the girth of required hollow rubber pad, the film stock at body two ends is put sulfuration in a mold, and support tube ensure that cavity communicates, and whole hollow rubber pad is connected as a single entity after joint sulfuration, under boiling and high pressure, be not easy fracture, can repeatedly use, longer service life.
Description
Technical field
The invention belongs to for reaction under high pressure tank body port sealing pad technical field, relate to the preparation method of hollow rubber pad and this rubber pad concretely.
Background technique
In the fields such as chemical industry, vacuum reaction still is widely used.Most vacuum reaction still adopts the sealing of hollow rubber pad.This hollow rubber pad is in use crushed, and insert in high-temperature water by the hollow rubber pad after using, the air in its cavity is through adding thermal expansion, and hollow rubber pad returns to again original shape, and its performance also can be recovered substantially.The hollow rubber pad of current use, owing to being subject to the impact of production technology, first being produced body, is then docked, and adopts binder bonding at docking port place.There is following defect in the hollow rubber pad that the method is produced: at high temperature under high pressure, binder is easily aging, and jointing easily ruptures, and working life is short; In-furnace temperature is high, causes product rejection in reactor, accident of also blasting after sealing gasket fracture.
Summary of the invention
First technical problem that the present invention solves just is to provide and a kind ofly repeatedly can uses, long service life, the hollow rubber pad that ruptures is less likely to occur.
For solving the problems of the technologies described above, the technological scheme that the present invention proposes is: comprise rubber cushion body and cavity, in the cavity of described rubber cushion body joint, be provided with support tube.
Its additional technical feature is:
The external diameter of described support tube is slightly less than the internal diameter of described cavity;
Described support tube is metallic hose.
Second technical problem that the present invention solves just is to provide the hollow rubber pad preparation method that a kind of method is simple, manufacturing efficiency is high.
For solving the problems of the technologies described above, the technological scheme that the present invention proposes is:
This preparation method comprises the following steps:
The first step, charging
In the cavity of mould, insert film stock, above described film stock, place core, then above core, place film stock, cover die cover, described mould is stretched out at the two ends of described film stock, and the length of described core is greater than the length of mould, and described both mold ends is stretched out at the two ends of this core;
Second step, sulfuration
By the mold heated sulfuration with film stock, sulfurize temperature controls 150---and 170 DEG C, cure time is 35---45 minutes; Open die cover, extract core out, obtain the body of two ends with film stock;
3rd step, continues
The film stock of body one end to be inserted in mould together with part body, then the film stock that continues in a mold, core is inserted in the cavity of body, above core, cover film stock, make the film stock that continues and core stretch out outside mould;
4th step, continue sulfuration
By the mold heated sulfuration continued, sulfurize temperature controls 150---and 170 DEG C, cure time is 35---45 minutes; Open die cover, extract core out;
5th step, continues to continue
According to length needs, proceed to continue and continue vulcanisation step, until the difference of rubber cushion body girth and tube length is between 1/3-1/2 of die length;
6th step, joint
Support tube is inserted in body one end, body two ends are docked, and the other end of support tube is inserted the other end of body, joint is inserted in mould, and need continue film stock or wipe out film stock more than needed according to length, baking, sulfurize temperature controls 155---and 170 DEG C, cure time is 55---65 minutes; Open die cover, take out body;
7th step, packaging.
Its additional technical feature is:
In described first step charging and described 3rd step subsequent steps, the length that film stock stretches out mould is more than or equal to 10 centimetres;
Continue in vulcanisation step in described second step sulfuration and the 4th step, sulfurize temperature controls 158---and 162 DEG C, cure time is 39---41 minutes; In described 6th step joint step, sulfurize temperature controls 159---161 DEG C, cure time is 59---61 minutes.
Hollow rubber pad provided by the invention and preparation method thereof, compared with the existing technology comparatively have the following advantages: one, owing to being provided with support tube in the cavity of described rubber cushion body joint, in process of production, film stock is left all the time in body two ends, when tube length reaches the girth of required hollow rubber pad, the film stock at body two ends is put sulfuration in a mold, support tube ensure that cavity communicates, and whole hollow rubber pad is connected as a single entity after joint sulfuration, under boiling and high pressure, be not easy fracture, can repeatedly use, longer service life; Its two, because described support tube is metallic hose, not only make in joint cavity communicate, and there is elasticity, make the sealability of hollow rubber pad better; Its three, due in the charging of the described first step and described 3rd step subsequent steps, the length that film stock stretches out mould is more than or equal to 10 centimetres, ensure that the join strength of Liang Ge mould lap-joint rubber cushion body.
