Embodiment 1

[0012] Embodiment 1--adopting longifolene is the method for raw material production terpene resin:

[0013] Put 50kg of longifolene, 1kg of oligomeric diol, 5kg of diisocyanate, 0.5kg of organosilicon-modified polysiloxane and 0.05kg of anhydrous aluminum trichloride into the reactor and mix them evenly, and keep warm at 80°C for 20 minutes, followed by distillation.

[0014] The production cycle of the product terpene resin of this embodiment was shortened by 2 hours.

Embodiment 2

[0015] Embodiment 2--adopting longifolene is the method for raw material production terpene resin:

[0016] Put 55kg of longifolene, 5kg of oligomeric diol, 8kg of diisocyanate, 1kg of organosilicon-modified polysiloxane and 0.1kg of anhydrous aluminum trichloride into the reaction kettle, mix them evenly, and keep warm at 95°C for 10 minutes , followed by distillation.

[0017] The production cycle of the product terpene resin of this embodiment was shortened by 2 hours.

Embodiment 3

[0018] Embodiment 3--adopting longifolene is the method for raw material production terpene resin:

[0019] Put 52kg of longifolene, 2kg of oligomeric diol, 6kg of diisocyanate, 0.8kg of organosilicon-modified polysiloxane, and 0.07kg of anhydrous aluminum trichloride into the reactor, mix them evenly, and keep warm at 90°C for 15 minutes, followed by distillation.

[0020] The production cycle of the product terpene resin of this embodiment was shortened by 2 hours.

Abstract

The invention discloses a method for producing terpene resin by using longifolene as a raw material, and belongs to the technical field of rosin deep processing. The present invention adopts the following raw materials in parts by weight: 50 to 55 parts of longifolene, 1 to 5 parts of oligomeric diol, 5 to 8 parts of diisocyanate, 0.5 to 1 part of organosilicon-modified polysiloxane and 0.05 part to 0.1 part of anhydrous aluminum trichloride; including putting the above-mentioned raw materials longifolin, oligomeric diol, diisocyanate, organosilicon-modified polysiloxane and anhydrous aluminum trichloride into the reaction kettle and mixing uniformly, And heat-preserve and react at 80° C. to 95° C. for 10 minutes to 20 minutes, and then carry out distillation. The present invention adds a certain proportion of oligomeric diol, diisocyanate, organosilicon-modified polysiloxane and anhydrous aluminum trichloride in the preparation process, thereby effectively shortening the production cycle of the product terpene resin and reducing its cost .

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, in particular to a method for producing terpene resin by using longifolene as a raw material. Background technique [0002] Terpene resins are some thermoplastic block copolymers, which have the advantages of low odor, high hardness, high adhesion, good oxidation resistance and thermal stability, good compatibility and solubility, especially EVA series, SIS series, SBS series, etc. Hot melt has excellent compatibility, weather resistance and thickening effect. It is widely used in adhesives, adhesives, double-sided tapes, solvent-based glues, book bindings, color packaging, tapes, olefin tapes, kraft paper card tapes, Tape label, wood glue, pressure sensitive adhesive, hot melt adhesive, sealant, paint and ink and other polymer modifiers, etc. But it also has some disadvantages that cannot be ignored, that is, the disadvantages of long preparation period and high cost.
