The invention relates to a
processing method of
pine resin and belongs to the field of
rosin production. The
processing method of
pine resin comprises the following steps of: a, dissolving, namely dissolving the
pine resin by adopting a dissolving solution, wherein the dissolving solution comprises the following components in percentage by weight: 55-82% of
turpentine oil, 17.5-44.5% of water and 0.1-0.5% of
oxalic acid; b, clarifying and colating, namely placing the dissolved pine resin liquid in a transition pot to be clarified and then colating to obtain colature; c,
acid washing, namely adding the
oxalic acid for washing; d, washing, namely adding hot water for washing; e, clarifying and carrying out refined
filtration, namely placing the pine resin liquid into the transition pot to be clarified and then carrying out refined
filtration; and f, heating and distilling, namely placing the pine resin liquid in a rectifying
tower to be subjected to the heating and distilling, so that
rosin and
turpentine oil finished products are respectively obtained. The
processing method of
rosin provided by the invention has the beneficial effect that the qualities of the rosin and
turpentine oil obtained by processing pine resin are excellent, so that demand of downstream industries is met.
