Abstract
The invention discloses tyre repair rubber which is composed of rubber A and rubber B with weight ratio of 1:0.5-1. A vulcanization system used in the rubber A comprises sulphur, dibenzothiazyl disulfide and C7H5NS2. A vulcanization system used in the rubber B comprises N-Ethyl-N-phenyldithiocarbamic acid zinc salt, zinc dibutyl dithiocarbamate, diphenylguanidine and triethanolamine. According to the tyre repair rubber, the special vulcanization systems are used, vulcanization can be achieved on a normal-temperature condition, and after the rubber A and the rubber B are mixed evenly, the vulcanization can be achieved at the temperature of about 25 DEG C and within 10-24 hours. A heating vulcanization technology is of no need, the tyre rubber cannot be damaged by aging, original tyre mechanical physical performance can not be lowered, and the tyre repair rubber has the advantages of being strong in adhesive strength.
