Embodiment 1

[0022] The preparation method of automobile rubber composition of the present invention, comprises the following steps:

[0023] S1. Weigh each raw material according to the weight and number ratio of Example 1 in Table 1; open the mill, raise the temperature to 32°C, set the roll distance to 0.6mm, and add natural rubber, styrene-butadiene rubber and butadiene rubber at the same time In the open mill, after plasticizing for 14.7 minutes, discharge the glue, pound, press, tablet, cool to room temperature, and park for 3 hours to obtain the plasticized rubber;

[0024] S2. Raise the temperature of the internal mixer to 89°C, adjust the roll distance to 3 mm, add 35% wt of the masticated rubber described in S1, and add the high wear-resistant carbon black and modified white weighed in S1 after mixing for 6 minutes. Carbon black, benzoic acid, phthalic anhydride, rubber leveling agent, tackifying resin E1102, aromatic oil, after mixing for 3.2 minutes, add zinc oxide, stearic aci...

Embodiment 2

[0027] The preparation method of automobile rubber composition of the present invention, comprises the following steps:

[0028] S1. Weigh each raw material according to the ratio of parts by weight; turn on the open mill, raise the temperature to 35°C, set the roll distance to 0.8mm, add natural rubber, styrene-butadiene rubber and butadiene rubber into the open mill at the same time, plastic After refining for 10 minutes, remove the glue, tamping, pressing, tableting, cooling to room temperature, and then park for 3.8 hours to obtain plasticized rubber;

[0029] S2. Raise the temperature of the internal mixer to 82°C, adjust the roll distance to 3.3mm, add 32%wt of the plasticizing rubber described in S1, and add the high wear-resistant carbon black and modified carbon black weighed in S1 after mixing for 8 minutes. Silica, benzoic acid, phthalic anhydride, rubber leveling agent, tackifying resin E1102, aromatic oil, after mixing for 4.8 minutes, add zinc oxide, stearic acid...

Embodiment 3

[0032] The preparation method of automobile rubber composition of the present invention, comprises the following steps:

[0033] S1. Weigh each raw material according to the weight and number ratio of Example 3 in Table 1; open the mill, raise the temperature to 30°C, set the roll distance to 0.7mm, and add natural rubber, styrene-butadiene rubber and butadiene rubber at the same time In the open mill, after plasticizing for 6 minutes, discharge glue, tamping, pressing, tableting, cooling to room temperature, and then park for 4.2 hours to obtain plasticizing rubber;

[0034] S2. Heat up the internal mixer to 85°C, adjust the roll distance to 3.5mm, add 30%wt of the masticated rubber described in S1, and add the high wear-resistant carbon black and modified carbon black weighed in S1 after mixing for 5 minutes. Silica, benzoic acid, phthalic anhydride, rubber leveling agent, tackifier resin E1102, aromatic oil, after mixing for 4.4 minutes, add zinc oxide, stearic acid, activato...

The rubber composition has good wear resistance and heat resistance, so that the rubber composition with good comprehensive performance used for the automobile is obtained.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber composition for automobiles and a preparation method thereof. Background technique [0002] Tires are circular elastic products for vehicles, agricultural machinery, construction machinery, and aircraft take-off and landing. It is the main accessory of vehicles, agricultural machinery, construction machinery and aircraft, etc. It can absorb the vibration and external impact caused by uneven road surface, making the ride comfortable. Tires are the main products in the rubber industry, and the amount of rubber they consume accounts for 50%-60% of the total amount of rubber, and is an indispensable strategic material. The tread of the tire should be in direct contact with the road surface. Therefore, the rubber used for the tire should have good wear resistance, low rolling resistance and noise, and also have excellent heat resistance and puncture resistance. The wear resi...
