Abstract
The invention discloses a high-temperature short vulcanization process for a transverse rubber backstop, relating to an improvement on the conventional vulcanization process for the transverse backstop. The transverse backstop is produced according to the following steps and process parameters: A, setting the plate temperature of a vulcanizing press to ensure that the temperature of a mold cavity in a mould is 100-170 DEG C; B, recycling a rubber material to enable the rubber material to be rolled to be round after being recycled so as to be conveniently placed into a rubber injection cylinder; C, setting the pressure of the vulcanizing press to ensure that the pressure inside the mould is 5-15MPa; D, setting the vulcanizing time to be 10-15minutes; E, placing a lower bottom plate of the backstop into a steel shot sand blasting machine to blast shots for 8-20minutes, and placing a hard backstop into a quartz sand blasting machine to blast sand for 10-30minutes; and F, placing the formed rubber material into the rubber injection cylinder of the mould to pressurize and vulcanize. The high-temperature short vulcanization process can be used for forming the transverse rubber backstop through high-temperature short vulcanization and ensuring that a product with the rubber layer thickness of 20-50mm is vulcanized to be matured. By using the high-temperature short vulcanization process, the vertical rigidity of the product can meet the requirement of an index when the product is compressed to 10-22mm under the condition of a vertical loading force.
Description
Technical field
The present invention a kind of novel transverse rubber backstop sulfuration process, relate to the process modification to existing production transverse rubber backstop.
Background technology
Produce at present transverse rubber backstop, cure time is long, and production efficiency is low, and when product is in working order time, vertical stiffness curve rises rapidly, while causing compressing 10mm ~ 22mm, the vertical stiffness requirement that can not touch the mark, has had a strong impact on the effect of product performance stop.Therefore there is the poor problems of combination property such as long performance consuming time is not up to standard in existing processing technology.
Summary of the invention
The object of this invention is to provide a kind of production technology of transverse rubber backstop, the properties of product that the invention solves existing technique existence are not up to standard, and cure time is long, the problem that production efficiency is low.
The high-temperature short vulcanization process of transverse rubber backstop of the present invention carries out in accordance with the following steps:
1) set vulcanizing press temperature, to ensure that the die cavity temperature of mould reaches 100 ~ 170 DEG C.
2) ironware of handling well is packed in mould.In this process, ironware has not allowed pollute and collide with;
3) freshening sizing material, make freshening after sizing material be rolled into circle, facilitate sizing material to put into Glass cement squeezing device; In the time of freshening sizing material, sizing material must carry out thin-pass 3 ~ 5 times, is then rolled into cylindrically, is finally curled into circle.
4) setting vulcanizing press pressure is 12 ~ 20MPa, ensures that the pressure that mould inside bears is 5 ~ 15MPa.
5) setting cure time is 5 ~ 15min short vulcanization.
6) preformed sizing material is put into Glass cement squeezing device, ensure that sizing material is not higher than Glass cement squeezing device, then press cure.
Preferably, in step 1), be 130 ~ 190 DEG C by upper flat plate Temperature Setting on used vulcanizing press, lower plate temperature is set as 120 ~ 180 DEG C, thereby ensures that mold cavity temperature is 100 DEG C ~ 170 DEG C.
Preferably, step 2) in base plate must be put into shot sand spray machine sand spray, time is 8 ~ 20min, hard stop is put into quartzy sand-blasting machine sandblast, the time is 10 ~ 30min;
Preferably, in step 3) when freshening sizing material, sizing material must thin-pass 3 ~ 5 times, is then rolled into cylindrically, is finally curled into circle.
Transverse rubber backstop production technology of the present invention, can make product sulfuration within a short period of time ripe, enhances productivity.
The present invention has done further improvement to original horizontal stop production technology.In order to improve performance and the production efficiency of product, in process of production, improve die cavity temperature, shorten cure time.After changing, can only meet the rigidity requirement of product by adjusting rubber hardness, sizing compound formula and production technology are all brought great convenience.
