[0031]A method for producing a high-performance copolymer resin product for producing a tire tire debris comprising the steps of:
[0032]1), according to the mass ratio carbon five dibaine: monoolefin: styrene: indole: solvent is (1 ~ 15): (1 ~ 15): (1 ~ 10): (1 ~ 10) :( 1 ~ 15), weigh the reaction material and solvent, and mix well.
[0033]2) Adding a solvent bottom to the reactor before the addition of the reaction material, then add a catalyst of 1 to 5% of the total mass of the mixed material; the catalyst is a trichloride powder, a liquid trichloride catalyst and trifluoro One or more mixtures of the boronethyl ether complex.
[0034]3), the temperature is reacted in the reaction kettle to react back to the mixed material, and the reaction temperature is controlled at 50 to 90 ° C, and the reaction kettle pressure is controlled at less than 3 MPa, and the reaction time is from 1 to 5 h. The present invention adds a mixed reactive material using a metering pump, and controls it over 0....
Embodiment 1
[0041]100 g of pentadiene, 50 g of isopustom, 50 gα-methylstyrene, 50 g of hydrotherminal mixing, then adding a toluene solvent 100g to the reactor, and then 5 g of a trichloride powder as a catalyst. After the temperature of the reaction reaches 50 ° C, the mixed material was added to the metering pump, and the mixed material was added and the mixed material was added over 30 min. After 1 h to be reacted, the reaction product was washed 5 times. It is then filtered through reduced pressure, and the final product is obtained. The softening point of the resulting resin product is 85 ° C, and the color number of the Gardner is 5, the molecular weight Mn is 720, the molecular weight width distribution 1.8, the glass conversion temperature is 35 ° C, The resulting resin product 300% of the rubber application test was 8 MPa, the puller strength reached 31MPa, the hardness before and after rubber aging was 67, 71, the door niosphere and the doorbus time were also suitable, the temperature...
Embodiment 2
[0043]A 150 g of carbon-pentanbon olefin (mass ratio pentadiene: isoprene = 3: 2), 40 g isopustom, 30 g of β-methylstyrene, 70 g of hydrauline mix is uniform. Then, a toluene solvent 100 g was added to the reactor, followed by 5 g of aluminum chloride powder as a catalyst. When the temperature of the reaction reacted at 60 ° C, the mixed material was added to the metering pump, and the mixed material was added and the mixed material was added over 30 min. After 2 h to be reacted, the reaction product was washed 3. Then, the final product was filtered, and the resulting resin product was 92 ° C, and the color number of the resulting resin product was 6, the molecular weight Mn was 810, the molecular weight width distribution 2.0, the glass conversion temperature 37 ° C, obtained The resin product is 300% of the rubber application test to 9 MPa, the puller strength of 32 MPa, the temperature of the temperature is 0.6 at 0 ° C, and the temperature of 60 ° C is 0.11.
