Embodiment Construction

[0012] Such as figure 1 Shown, the production technique of phellandrene resin, its operation comprises polymerization-washing-distillation-sheet making, in described polymerization process, toluene, catalyst are put into reactor, then put into phellandrene and carry out polymerization reaction, wherein , the weight ratio of phellandrene, toluene and catalyst is 100:150:4; the catalyst adopts Lewis acid iodine or iron. In the polymerization process, the temperature in the reactor is -10--0°C, and the polymerization reaction time is 8 hours.

[0013] Filtration processes are respectively added before and after the water washing process.

[0014] In the sheet-making process, the finished product is a solid transparent substance.

[0015] The performance contrast of the present invention and traditional product:

[0016] Phellandrene resin: color (iron-cobalt method) not greater than 2; softening point (ring and ball method) 135-150°C; acid value 0.5; saponification value not ...

Abstract

The invention discloses a phellandrene resin production process, which includes polymerizing, washing, distilling and slicing. The phellandrene resin production process is characterized in that during the polymerizing procedure, toluene and catalyst are added into a reactor and are polymerized after phellandrene is added into the reactor, the weight ratio of the phellandrene, the toluene and the catalyst is 100:150:4, and the catalyst is lewis acid iodine or iron. The phellandrene resin production process has the advantages that (1), the phellandrene resin and the production process thereof are originated in the nation; (2), the phellandrene resin production process utilizes self-researched composite high-activity catalyst which is based on the lewis acid catalyst; (3) the produced phellandrene resin is high in polymerization degree, high in recovery rate and low in cost; (4) the softening point of the produced phellandrene resin is higher than 135 DEG C and even can reach 150 DEG C; and (5), the produced phellandrene resin is high in polymerization degrees and large in molecular weight, few in low-boiling-point substances and stable in structure, and is fine in distilling and separating effect when being distilled and excellent in inoxidizability without any oxidation inhibitor.

Description

technical field [0001] The invention relates to a production process of a tackifier, in particular to a production process of phellandrene resin. Background technique [0002] Traditionally used tackifiers such as hydrogenated petroleum resins, hydrogenated rosin resins, β-pinene resins and imported terpene resins have the following disadvantages: their polarity is relatively large, and they are more compatible with elastomers such as EVA, SIS, and SBS than terpenes. The resin-like resin is slightly inferior, the softening point of the product is not too high, and the stability and high temperature resistance of the produced glue are slightly worse. Contents of the invention [0003] In order to overcome above-mentioned deficiency, the object of the present invention is to provide the production technology of the phellandrene resin that the softening point of a kind of tackifier is high, product structure is stable. [0004] In order to achieve the above object, the techn...
