Embodiment
Further describe the present invention below in conjunction with specific embodiment, advantage and disadvantage of the present invention will be more clear along with description.But these embodiment are only exemplary, scope of the present invention are not formed to any restriction.It will be understood by those skilled in the art that lower without departing from the spirit and scope of the present invention and can modify or replace details and the form of technical solution of the present invention, but these modifications and replacement all fall within the scope of protection of the present invention.
Purpose of the present invention is the material behavior that is to overcome styrene-butadiene rubber(SBR) itself, but a kind of styrene-butadiene rubber(SBR) formula of high-foaming is provided, to prepare the butadiene styrene rubber foaming material of high-foaming.
Styrene-butadiene rubber(SBR) formula of the present invention includes:
And above-mentioned whipping agent can be divided into two classes by its chemical structure:
(1) mineral-type: include bicarbonate of ammonia (Ammonium Bicarbonate) and sodium bicarbonate (Sodium Bicardonate).The two heat can discharge carbonic acid gas (CO
2) gas, can be used for making the class organic blowing agents such as perforating bipeltate goods (Open Cell Sponge) or cooperation AC for the manufacture of closed pore formula bipeltate goods.
(2) organic: this type of whipping agent heat can decomposite take nitrogen as main gaseous mixture.General all for the manufacture of closed pore formula bipeltate goods (Closed Cell Sponge).The organic whipping agent is different decomposition temperature and gas forming amount by its chemical structure difference.
Refer to the 1st figure, it uses above-mentioned styrene-butadiene rubber(SBR) formula, with the Production Flow Chart of the matrix material for preparing high-foaming styrene-butadiene rubber(SBR).
At first, as described in step S1, carry out rubber mastication (mastication): by used styrene-butadiene rubber(SBR) prior to the middle enforcement of ten thousand horsepowers of machines (Banbury) mastication, the time of mastication is different because of volume and the rotor speed of ten thousand horsepowers of machines (Banbury), treats that mastication is complete can rolling standby.The effect of mastication can utilize Mooney (Mooney) trier to measure.
For instance, the Mooney point of general styrene-butadiene rubber(SBR) (SBR 1502) is about 50 ~ 55, and the present invention is after the styrene-butadiene rubber(SBR) mastication, and Mooney point can be down between 30 ~ 35, so reaches the purpose of mastication.
Gimmick by the rubber mastication interrupts the molecular chain of styrene-butadiene rubber(SBR), and its chain length is shortened, and reduces to be entangled with and to make molecular chain more easily movable between molecular chain.
Continue, as described in step S2, carry out compounding rubber: styrene-butadiene rubber(SBR), tenderizer, weighting agent, strengthening agent and functional Synergist S-421 95 are mixed 5 minutes with ten thousand horsepowers (Banbury).Feeding sequence is main glue, functional Synergist S-421 95, weighting agent, strengthening agent, tenderizer, and it is between 90 to 100 ℃ that melting temperature is controlled, and is cooled to room temperature after mixing to deposit 24 hours; Afterwards again by the above-mentioned mixing rubber size completed with second wheel (Open Roller) and mixing 2 minutes halfs of vulcanizing agent, it is 70 ~ 80 ℃ that temperature is controlled, and after mixing completing, can carry out next flow process production.
Step S3 is described for another example, rolls laminating: first base cloth is coated with and then uses the rubber thickener through pasting machine (Coater).Again the above-mentioned rubber size mixed is sent in rolling press and utilized the rubber thickener to fit on base cloth, service temperature is between 90 ~ 100 ℃.Sizing material is set the thickness of calendering between 0.25 ~ 0.30mm, after calendering laminating sizing material, makes the combined type cladding that structure is rubber/fabric.This step can be adopted the continous way mode of production or be batched standby to next flow process.
Above-mentioned base cloth material is nylon fiber cloth, and also replaceable is polyester fiber cloth, cotton, polyester/nylon blending gauze and other different union yarn Woven Fabricss that form fiber.
Finally, as described in step S4, added sulphur: the matrix material of rubber/woven fabric structure prepared by last flow process carries out the continous way sulfur adding treatment.It adds the sulphur design temperature is 135 ~ 150 ℃, produces speed and is set as 15 ~ 20 yards of per minutes, and rubber prepared by last flow process/woven fabric structure matrix material adds sulphur with vertical type air oven (Oven).
Through sulfuration, finish, what get final product as shown in Figure 2 is positioned at by a base cloth 10 and a matrix material 14 that the high-foaming styrene-butadiene rubber(SBR) layer 12 on base cloth 10 forms.And 12, base cloth 10 and styrene-butadiene rubber(SBR) layer have one to follow the rubber paste bed of material 16.
The present invention interrupts the molecular chain of styrene-butadiene rubber(SBR) by the gimmick of rubber mastication, and its chain length is shortened, and reduces to be entangled with and to make molecular chain more easily movable between molecular chain.Secondly, add a large amount of tenderizers, to reduce the friction between molecular chain, improve the reactivity of molecular chain, the air chamber of foam material is more easily produced.Break through the material behavior of styrene-butadiene rubber(SBR) itself by above-mentioned two kinds of modes, allow the styrene-butadiene rubber(SBR) also can be as the material of high foaming material.
