example 1

[0020] Weigh 80g of poplar branches, dry them in the sun, put them into a carbonization furnace, heat up to 500°C under the protection of a nitrogen atmosphere, and carbonize them for 1 hour. Add the carbonized poplar branches to a pulverizer and pulverize them, and pass them through a 100-mesh sieve to obtain carbonized powder. The carbonized powder was soaked in a 3% sodium dodecylbenzene sulfonate solution in a ratio of 1:10, soaked for 1 hour, filtered, and dried to obtain a solid, and the modified carbonized powder was obtained. According to the mass ratio of 1:1, they were called Mix asbestos fibers and glass fibers to obtain mixed fibers. According to the mass ratio of 1:4, the mixed fibers are added to the silane coupling agent KH-550 and soaked. After soaking for 30 minutes, filter residues are obtained. The dried filter residue is pulverized and passed through a 200-mesh sieve to obtain modified fiber powder. The modified fiber powder and modified carbonized powder ar...

[0022]Weigh 90g of poplar branches, dry them in the sun, put them into a carbonization furnace, heat up to 525°C under the protection of a nitrogen atmosphere, and carbonize them for 1 hour. Add the carbonized poplar branches to a pulverizer to pulverize, and pass through a 110-mesh sieve to obtain carbonized powder. The carbonized powder was soaked in a 3% sodium dodecylbenzene sulfonate solution in a ratio of 1:10, soaked for 1 hour, filtered, and dried to obtain a solid, and the modified carbonized powder was obtained. According to the mass ratio of 1:1, they were called Mix asbestos fibers and glass fibers to obtain mixed fibers. According to the mass ratio of 1:4, the mixed fibers are added to the silane coupling agent KH-550 and soaked. After soaking for 35 minutes, filter residues are obtained. The dried filter residue is pulverized and passed through a 210-mesh sieve to obtain modified fiber powder. The modified fiber powder and modified carbonized powder are mixed at a...

[0024] Weigh 100g of poplar branches, dry them in the sun, put them in a carbonization furnace, heat up to 550°C under the protection of a nitrogen atmosphere, and carbonize them for 2 hours. Add the carbonized poplar branches to a pulverizer and pulverize them, and pass them through a 120-mesh sieve to obtain carbonized powder. The carbonized powder was soaked in a 3% sodium dodecylbenzene sulfonate solution in a ratio of 1:10, soaked for 2 hours, filtered, and dried to obtain a solid to obtain modified carbonized powder. According to the mass ratio of 1:1, they were called Mix asbestos fibers and glass fibers to obtain mixed fibers. According to the mass ratio of 1:4, the mixed fibers are added to silane coupling agent KH-550 and soaked. After soaking for 40 minutes, filter residues are obtained. The dried filter residue is pulverized and passed through a 220-mesh sieve to obtain modified fiber powder. The modified fiber powder and modified carbonized powder are mixed accordi...

Abstract

The invention discloses a preparation method of automatic inflation tire repair liquid, and belongs to the technical field of tire repair liquid preparation. The preparation method comprises the following steps: firstly, sun-drying and carbonizing polar branches, and then performing crushing modification to obtain modified carbonized powder; secondly, soaking asbestos fibers and glass fibers with a silane coupling agent, then performing filtration and freeze-drying, performing crushing and screening, then performing mixing and ultrasonic dispersion with the modified carbonized powder, castor oil, super-light clay and the like to obtain modified castor oil after crushing and screening, and then performing reduced pressure mixing with polyether glycol and styrene-butadiene rubber powder to obtain viscous fluid; and finally, taking milky liquid of a fresh rubber tree to mix with the viscous fluid and isopropyl benzene hydroperoxide, then filling the mixture into a tank, and introducing nitrogen to fully fill the reset volume of a part in the tank, thereby obtaining the automatic inflation tire repair liquid. The raw materials used in the preparation method disclosed by the invention are safe and noncorrosive, cannot corrode tire hubs, and cannot cause pollution to the environment; and the prepared tire repair liquid is strong in cementation force, and can be strongly attached to the lining surface of a tire to form a layer of protective film to ensure that the adhesive layer property of the tire is enhanced and the service life of the tire is prolonged, so that the tire repair liquid has a good application prospect.

Description

technical field [0001] The invention discloses a preparation method of an automatic inflatable tire repair fluid, and belongs to the technical field of tire repair fluid preparation. Background technique [0002] Microscopic holes in the tire rubber and poor contact between the tubeless tire and the rim can cause slow deflation. When the vehicle is running, the tires will be punctured by nails or sharp hard substances on the road, causing acute deflation. Long-distance high-speed driving, especially in hot summer, on scorching road surfaces will also cause higher and higher temperatures to accumulate locally in the tires, and eventually a tire blowout will occur. In the above cases, the lighter ones will cause the vehicle to break down, and the more severe cases will cause the car to roll over or control the car, and even cause a major accident of car crash and death. Accidents like this are common around the world. Therefore, since the beginning of pneumatic tires, peopl...
