Problems solved by technology

The "explosion-proof tires" that appear on the market are actually "run-flat tires". They are just tires with harder sidewalls than ordinary tires. The reinforced sidewalls greatly reduce the comfort and even affect the handling of the vehicle. performance, and the run-flat tires are expensive, but the service life is the same as that of ordinary tires. Not only that, because the run-flat tires have hard sidewalls, they cannot be replaced without professional tire changing tools. Incorrect replacement methods may even damage the tires. circle, which adds difficulty to the maintenance of the vehicle

Embodiment 1

[0028] Embodiment 1 Universal tire

[0029] The composition of the MSR compound is by weight percentage: 45% of elastomer, 40% of tackifier, 5% of softener, 1% of anti-aging agent, 2% of foaming agent, 6% of filler, and 1% of crosslinking agent. The steps are as follows:

[0030] The first step: quickly put each component of the rubber compound into four airtight small stirring tanks that have been preheated to 180°C-190°C, and stir automatically for 2 hours;

[0031] Step 2: Use a booster pump to pump the rubber in the four closed small stirring tanks into the main stirring tank that is preheated to 180°C-190°C, and continue to stir automatically for 2 hours;

[0032] Step 3: Then use a booster pump to pump the rubber in the main stirring tank into the semi-open glue collection box, and use circulating cooling water in the glue collection box to indirectly cool the glue to room temperature, and the taken out glue can be packaged until the end.

Embodiment 2

[0043] Embodiment 2 Special type tire for military and civilian use

[0044] The composition of the MSR rubber compound is as follows: 51% elastomer, 36% tackifier, 2% foaming agent, 7% softener, 2% filler, 1% anti-aging agent, 1% crosslinking agent. Wherein the preparation steps are roughly the same as those in Example 1, only the temperature conditions and time conditions are different, and Example 2 is after mixing for 1.5 hours under the condition of 250°C.

[0045] In addition, the method of applying the MSR compound to the tubeless tire is also roughly the same as in Example 1, wherein the thickness of the compound sprayed is 2mm, and the special type tire for military and civilian use of the present invention is obtained.

[0046] The obtained physical properties of MSR sizing material in embodiment 2 are specifically as follows:

[0047] Tensile strength ≤ 0.37MPa; tensile elongation ≥ 1500%

[0048] Softening point 108°C; initial viscosity ≥ 7MM

[0049] Peel stren...

Embodiment 3

[0051] Example 3 Truck tire

[0052]The composition of the MSR rubber compound is as follows: 45% elastomer, 43% tackifier, 5% filler, 6% softener, 1% anti-aging agent. The preparation steps are roughly the same as those in Example 1, only the temperature conditions and time conditions are different, and Example 3 is after kneading at 190° C. for 2.5 hours.

[0053] In addition, the method of applying the MSR sizing material to the tubeless tire is also roughly the same as in Example 1, wherein the sizing material is sprayed on the inner wall of the tubeless tire by a casting method, and the thickness of the sizing material spraying is 6mm, which obtains the load-bearing capacity of the present invention. Car tires.

[0054] The obtained physical properties of MSR sizing material in embodiment 3 are specifically as follows:

[0055] Tensile strength≤0.37MPa; tensile elongation≥1450%

[0056] Softening point 108°C; initial viscosity ≥ 7MM

[0057] Peel strength 21KN / M; low ...

Abstract

The invention relates to a memory of polymer synthetic rubber sealing (MSR) sizing material and a method thereof. The MSR sizing material comprises the following components in percentage by weight: 42 to 61.5 percent of elastomer, 35 to 54 percent of tackifier, 3 to 8 percent of softener and 0.5 to 1.5 percent of antiager. Tires sprayed by the MSR sizing material have functions of puncture resistance, leakage prevention, slow leakage prevention, energy conservation, little oil, capacity of realizing dynamic balance and the like.

Description

technical field [0001] The invention belongs to a rubber compound for automobile tires and a method thereof, in particular to an MSR rubber compound and a method thereof. Background technique [0002] Along with popularizing day by day of automobile, the road condition of road is more and more severe, cause automobile tire to be easy to be punctured and blow out, and blowout is very serious safety accident, especially blowout on expressway. And according to authoritative department statistics, in the car crash tragedy that tire blowout causes on the highway, have 60-70% to cause because tire blowout, therefore be badly in need of the industry to solve and prevent tire blowout problem. The "explosion-proof tires" that appear on the market are actually "run-flat tires". They are just tires with harder sidewalls than ordinary tires. The reinforced sidewalls greatly reduce the comfort and even affect the handling of the vehicle. performance, and run-flat tires are expensive, bu...
