preparation example Construction

[0014] Modified coumarone petroleum resin of the present invention and preparation method thereof, its steps are as follows:

[0015] Step 1, feed the raw material HW-263-008-04 into the pretreatment device to make it into a fluid liquid. No matter the raw material HW-263-008-04 is in liquid, solid or semi-solid semi-liquid state, it enters the raw material pretreatment device according to the measured ratio to make it into a fluid liquid.

[0016] Step 2, the raw materials are put into the metering tank for metering, and put into the reaction kettle to carry out the polymerization reaction. The raw material measurement is: cyclopentadiene 10.55%-15.58%, acrolein 1.67%-2.85%, acrylonitrile 8.99%-10.95%, 2-2 hexadiene 0.55%-1.45%, 1,4 dihydroxy 2-butane 32.96%-40.46% ene, 0.65%-1.35% heptylonitrile, 13.85%-15.96% carbon dioxide, 0.85%-1.55% styrene, 1.25%-1.88% 2-allylphenol, 3.85%-4.69% acrylic acid, Hydroxypropyl nitrile 1.45%-2.55%, cyclopentenylmethylpyridine 1.35%-2.45%,...

Abstract

The invention discloses modified coumarone petroleum resin and a preparation method thereof. The preparation method comprises the steps of firstly adding a raw material HW-263-008-04 into a pretreatment device, enabling the raw material to become flowing fluid; entering into a gauge tank for metering, pumping into a reaction still for polymerization reaction; adding an initiator A for free radical polymerization when the polymerization reaction is performed, adding auxiliaries B and C for cross-linked polymerization, adding a polymerization inhibitor D to terminate polymerization; performing distillation when the polymerization is finished, distilling out the unpolymerized components; emptying, smashing, and packaging the distilled product, then a finished product of the modified coumarone petroleum resin is obtained. According to the modified coumarone petroleum resin and the preparation method thereof, the distillation generated in a production process of imidacloprid and induction residue HW-263-008-04 are utilized to produce the modified coumarone petroleum resin, the modified coumarone petroleum resin and the preparation method can change waste into valuable, improve environment, reduce pollution, and bring benefit to society and people.

Description

technical field [0001] The invention belongs to the technical field of resin preparation, in particular to a modified coumarone resin and a preparation method thereof. Background technique [0002] At present, the domestic production of coumarone petroleum resin mainly uses carbon nine, carbon five, ethylene tar, etc. as raw materials for production and processing. The process generally adopts catalytic polymerization or thermal polymerization, which not only has extremely high production costs, but also produces a large amount of pollutants, which is easy to cause Environmental pollution has caused a bad impact on society and the lives of the people, especially in the production process will produce a large amount of distillation and reaction residue HW04 pesticide waste (see the national list of hazardous waste, such as 263-008-04, for the convenience of description , will be referred to as HW-263-008-04) will cause great harm to the environment and human body. The main c...
