Embodiment 1
[0031] The raw material formula used is:
[0032] SBS90kg, petroleum resin 17kg, polymerized rosin 16kg, rosin 25kg, terpene resin 140kg, cyclohexane 2.7kg, dichloromethane 1.9kg, ethyl acetate 84kg, 6# solvent oil 313.4kg, dichloroethane 43.3kg.
[0033] Its production method is as follows: (1) material preparation: at normal temperature, polymerized rosin, petroleum resin and rosin weighed according to the formula are crushed into uniform blocks with a diameter of about 50mm with a manual pounder, and can be ground into fine powder for better effect. Well, dissolve more lumps. (2) 6# solvent naphtha and ethylene dichloride of above-mentioned formula described weight are pumped in the stirred tank with the pumping pump, in order to avoid the material spilling that artificial dumping causes, reduce waste of material and cause the risk of environmental pollution, and Reduce labor intensity. (3) Pour the petroleum resin and rosin into the stirring tank according to the weight ...

[0035] The raw materials used are:
[0036] SBS338.4kg, petroleum resin 34kg, polymerized rosin 9kg, rosin 17kg, terpene resin 270kg, cyclohexane 5kg, methylene chloride 8kg, ethyl acetate 170kg, 6# solvent oil 530kg, dichloroethane 58.7kg.
[0037] Its production method is as follows: (1) material preparation: at normal temperature, the polymerized rosin, petroleum resin, and rosin of the above weight are crushed into uniform blocks with a diameter of about 50 mm. (2) 6# solvent naphtha and ethylene dichloride of above-mentioned weight are sucked in the stirred tank with the suction pump. (3) Pour the petroleum resin and rosin of the above weight into the stirring tank respectively, then add the SBS and terpene resin into the stirring tank according to the above weight, cover the lid of the stirring tank, and then start the motor to stir for 3 hours, then stop the motor . (4) Open the cover of the stirred tank, and now the rosin and other raw materials have dissolved a part...
