Abstract:
      Abstract：The application of four kinds of tackifying resins （butyl phenol acetylene resin，super tackifying resin BHK1360，alkyl phenol-formaldehyde resin and C5 petroleum resin） in the carcass cord compound of agricultural radial tire was studied. The results showed that，after adding tacking resin into the carcass cord compound of agricultural radial tire，the carbon black dispersion of the vulcanizate was improved，the shore A hardness，tensile strength，elongation at break，H extraction force and cord adhesion increased to varying degrees，the adhesion of the carcass of the finished tire was enhanced，and the durability was significantly improved. In comparison，the modification effects of butyl phenol acetylene resin and super tackifying resin BHK1360 on the carcass compound were more significant，followed by alkyl phenolformaldehyde resin，and the effect of C5 petroleum resin was the least.
