Description
【Technical field】
The invention belongs to newtrex preparing technical field, and in particular to a kind of shallow using newtrex crude product as raw material production
The method of color newtrex.
【Background technology】
Newtrex is based on dimer, the mixture containing rosin and pinoline etc., is not crystallized, softening point compares rosin
It is high.Dimer there are about 20%-50%, more stable, not oxidizable.Molecular formula is C40H60O4.90-120 DEG C of softening point, acid number
150mgKOH/g or so.Newtrex due to the increase of relative molecular mass and partially removing for double bond, thus with lighter color,
The features such as acid number is low, viscosity is big, do not crystallize, softening point is high, compatibility is good, anti-oxidant excellent, durability is strong.Be dissolved in toluene, gasoline,
The organic solvents such as petroleum ether, chloroform, dichloroethanes.
The polypale that now prepared by tradition can not reach application requirement, it is necessary to which polypale is to meet market
Need.
【The content of the invention】
The technical problem to be solved in the present invention is to provide one kind light polymerization pine is produced by raw material of newtrex crude product

Enter hydrogen, temperature reaction, fused mass after reaction is made；
S3：Then release and turpentine oil is distilled off, polypale is made.
Further, composite antioxidant described in step S2 by antioxidant MB, antioxidant DNP by weight 10-20:5-12
Composition.
Further, the composite antioxidant is by antioxidant MB, antioxidant DNP by weight 18:6 compositions.
Further, newtrex raw material crushed material described in step S2, turpentine oil, composite antioxidant, platinum catalyst, silicon
The weight of diatomaceous earth is than 1:2.8-5.5:0.002-0.005:0.02-0.05:0.005-0.012.
Further, the newtrex raw material crushed material, turpentine oil, composite antioxidant, platinum catalyst, diatomaceous heavy
Measure ratio 1:4:0.004:0.03:0.01.
Further, the pressure of hydrogen described in step S2 is 5-25MPa.
Further, the pressure of the hydrogen is 20MPa.
Further, it is warming up to 180-220 DEG C described in step S2.
Further, 200 DEG C are warming up to described in step S2.
Further, the reaction time described in step S2 is 4-6h.
The invention has the advantages that：
(1) 8h is heated at 180 DEG C by embodiment 1-3 and comparative example 1-4 newtrex, then measures resin color and luster,
Data show, embodiment 1-3 newtrex color and luster only rises 3-5 No. Ha Sense, and comparative example 1-4 newtrex
Color number rises 10-13 No. Ha Sense, illustrates that newtrex stability made from embodiment 1-3 is high.
(2) added from embodiment 2 and comparative example 1-4 data, composite antioxidant, platinum catalyst, diatomite in catalysis
Synergy is served in hydrogen, significantly reduces newtrex color and luster；This is probably that composite antioxidant plays a part of light-colored agent；
Platinum catalyst plays a part of catalytic hydrogenation；Diatomite can disperse platinum catalyst, so that effective area increases, Ke Yiti
Its high activity, therefore composite antioxidant, platinum catalyst, diatomite serve synergy in catalytic hydrogenation newtrex, show
Work improves newtrex color and luster.
