Abstract
The invention discloses a preparation method of light-colored terpene resin, and belongs to the technical field of rosin deep processing. The preparation method comprises the steps that 25-30 parts by weight of methylbenzene, 30-35 parts by weight of turpentine, 0.1-0.2 part by weight of aluminum trichloride anhydrous, 0.2-0.3 part by weight of chlorotrifluoroethylene and 0.05-0.1 part by weight of tetrafluoroethylene are put into a reaction kettle to be mixed to be uniform, heat preservation reacting is conducted for 0.5 h to 1 h at 0 DEG C to 5 DEG C, and distilling is conducted. According to the preparation method of the light-colored terpene resin, on the basis of a preparation method of existing terpene resin, due to the fact that a certain proportion of chlorotrifluoroethylene and 0.05-0.1 part of tetrafluoroethylene are added in the preparation process of the light-colored terpene resin, the color of the prepared product terpene resin becomes lighter.
Description
Technical field
The invention belongs to Colophonium deep process technology field, the preparation method of a kind of light color terpene resin.
Background technology
Terpene resin is some thermoplastic block copolymers, there is low abnormal smells from the patient, high rigidity, high adhesion force, non-oxidizability and Heat stability is good, the compatibility and the advantage such as dissolubility is good, SIS system of EVA system especially, the thermosols such as SBS system have the excellent compatibility and weatherability and Efficient Adhesive Promotion, it is widely used in adhesive, solid, two-sided tape, solvent-borne type glue, bookbinding version, color fills, adhesive plaster, alkene adhesive plaster, kraft paper card adhesive plaster, tapes labels, carpenter's glue, pressure sensitive adhesive, thermosol, fluid sealant, paint and the aspect such as ink and other polymer modification agent.But it is deeper to there is also some very important shortcomings, i.e. color.
Summary of the invention
The present invention provides the preparation method of a kind of light color terpene resin, and the terpene resin that the method prepares has light-colored advantage.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
By weight, 25 parts～30 parts of toluene, 30 parts～35 parts of Oleum Terebinthinaes, 0.1 part～0.2 part of aluminum trichloride (anhydrous), 0.2 part～0.3 part of CTFE, 0.05 part～0.1 part of tetrafluoroethene are put into mix homogeneously in reactor, and at 0 DEG C～5 DEG C insulation reaction 0.5 hour～1 hour, then distill.
Owing to using technique scheme, there is advantages that
The present invention is on the basis of the preparation method of existing terpene resin, by adding a certain proportion of CTFE, tetrafluoroethene in its preparation process so that the product terpene resin color that the present invention prepares becomes more shallow.
