The invention relates to a modified cured rubber compound which comprises (i) the rubber components of natural rubber or synthetic rubber, (ii) methano donator, (iii) aralkyl substituted phenol resin as the methano acceptor, wherein the aralkyl substituted phenol (resorcin) methano donator resin can be prepared by reacting the substituted or non-substituted phenol compound, vinyl aromatic compound and aldehyde and/or ketone in the presence of organic metal phosphate or phosphite ester catalyst. The inventive methano acceptor has lower smoke degree than R-80 (resorcin-80). And in the tension strength and dynamic mechanical property test, the aralkyl substituted resorcin phenol resin has better performance than R-80 and resorcin-formaldehyde (RF) resin.
