Abstract
The invention discloses a compensation air bag rubber pipe and a production method, and belongs to the technical field of rubber. The compensation air bag rubber pipe comprises, by weight, 100 parts of NBR, 0-30 parts of liquid NBR, 5-10 parts of factice, 10-30 parts of E-74P, 5-10 parts of DOS, 5-10 parts of N550, 1-2 parts of Si69, 1-2 parts of sulfur, 1-2 parts of TMTD and 1.5-2 parts of CZ in a sulfuration mode. The salt-bath sulfuration technology is adopted, and pure rubber pipes which are low in hardness, small in wall thickness and large in diameter can be produced and used for train shock absorber compensation air bags.
Description
Technical field
The invention belongs to field of rubber technology, soft, the 2 ± 0.15mm thin-walled train vibroshock that is thick, diameter >=50mm particularly relating to a kind of 45 ± 5 Shao Er A compensates air bag sebific duct and production method.
Background technology
In traditional sebific duct industry, rubber hardness generally more than 60 degree, sebific duct more than wall thickness 2mm, sebific duct diameter seldom has the situation being greater than 50mm, has skeletal support inside general sebific duct, braided construction hose or fabric hose, such sebific duct has well very property, and when sulfuration, sebific duct can not be out of shape.But require that (sebific duct cross section can not be circular to the pure glue sebific duct of the soft of rubber 45 ± 5 Shao Er A, 2 ± 0.15mm sebific duct wall thickness, more than diameter 50mm herein simultaneously, can for oval) use conventional rubber formula, conventional vulcanized tank, there is a lot of problem in the sulfuration of microwave vulcanization machine, the low forcing machine of such as rubber hardness is difficult to extrude, and extrudes inhomogeneity of wall thickness even.With conventional vulcanized tank sulfuration, stick together for preventing rubber tube inner wall and must overlap fuse, sebific duct is hung because influence of gravity there will be sebific duct upper and lower inhomogeneity of wall thickness even phenomenon during sulfuration, the situation that sebific duct horizontal positioned be there will be again compressive deformation bottom sebific duct occurs, can not ensure the homogeneity of sebific duct wall thickness.With the sulfuration of microwave vulcanization machine, sebific duct is extruded rear because not shaping by quick high-temp, there will be the phenomenon that inwall sticks together, there is impression lower surface in microwave drying tunnel.If use vulcanizing press to carry out the mode of molded vulcanization, because conventional vulcanization machine hot-plate size is limited, also can only the sebific duct of sulfuration length within 1 meter, be difficult to when sebific duct length is greater than 1 meter carry out molded vulcanization.And this vulcanization complex technical process, production efficiency is low, is difficult to meet the demand produced in enormous quantities.
Summary of the invention
The object of the invention is to the deficiency of improvement prior art and a kind of soft, thin-walled thick, large diameter compensation air bag sebific duct and sulfuration production technique are provided.
The object of the present invention is achieved like this, a kind of compensate air bag sebific duct, be characterized in by weight part be: the NBR of 100 parts, the liquid NBR of 10 ~ 20 parts, the ointment of 5 ~ 10 parts, the E-74P of 15 ~ 30 parts, DOS, the N550 of 5 ~ 10 parts, the Si69 of 1 ~ 2 part, the Sulfur of 1 ~ 2 part, the TMTD of 1 ~ 2 part, the CZ sulfuration of 1.5 ~ 2.5 parts of 5 ~ 10 parts form.
In order to realize object of the present invention further, can be by weight part: the NBR of 100 parts, the liquid NBR of 10 parts, the ointment of 8 parts, the E-74P of 20 parts, DOS, the N550 of 5 parts, the Si69 of 1.5 parts, the Sulfur of 1.5 parts, the TMTD of 1.2 parts, the CZ sulfuration of 2 parts of 5 parts form.

In order to realize object of the present invention further, can be by weight part: the NBR of 100 parts, the liquid NBR of 20 parts, the ointment of 8 parts, the E-74P of 25 parts, DOS, the N550 of 10 parts, the Si69 of 1.7 parts, the Sulfur of 1.2 parts, the TMTD of 1.5 parts, the CZ sulfuration of 2.2 parts of 10 parts form.
The production method of compensation air bag sebific duct described above, is characterized in adopting salt bath vulcanization production technique, salt temperature 200-220 DEG C, extruded velocity setting 15-20 m/min, curing time 4-8 minute.
In order to realize object of the present invention further, can be adopt salt bath vulcanization production technique, salt temperature 210 DEG C, extruded velocity sets 20 ms/min, curing time 5 minutes.
In order to realize object of the present invention further, can be adopt salt bath vulcanization production technique, salt temperature 210 DEG C, extruded velocity sets 25 ms/min, curing time 4 minutes.
In order to realize object of the present invention further, can be adopt salt bath vulcanization production technique, salt temperature 210 DEG C, extruded velocity sets 16.5 ms/min, curing time 6 minutes.
Feature of the present invention and beneficial effect as follows:
The present invention compensates in air bag rubber hose component and adds liquid NBR and ointment, effectively can reduce rubber hardness, improves caoutchouc elasticity; Add E-74P, it is a kind of low specific surface area white carbon black, and specific surface area is at 60m
2/ below g, its advantage is to fill in a large number and rubber hardness can not be significantly improved, and obviously improve the compression set of rubber, and after adding E-74P white carbon black, Mooney viscosity of rubber increases to some extent simultaneously, thus improve rubber very row, make rubber be easier to extrude and keep dimensional stabilizing; Add appropriate carbon black N550 to improve the intensity of rubber, make up the reinforcing slightly poor shortcoming of E-74P.
This sebific duct adopts and extrudes---salt bath vulcanization quantity-produced mode, and whole production line is mainly divided into following components: forcing machine, conveying belt, the adhesive tape of half meter long float on brine sparge high-temperature shaping above salt solution, adhesive tape immerses in salt solution and carries out salt bath, cleaning; Salt used is the mixture of finished product salt, KCl, nitrate etc.Sebific duct is shaped by brine sparge quick high-temp after forcing machine is extruded, immerse again in salt solution and carry out baking, because there is salt solution to enter in sebific duct, so rubber tube inner wall can not adhere to together, this ensure that the homogeneity of sebific duct wall thickness, different according to formula, grope through long-term experiment, adopt the salt bath vulcanization production technique being applicable to different ingredients, by the rational allocation to basal rate, temperature and time, produce high-quality compensation air bag sebific duct.
