Embodiment 1

[0041] Embodiment 1: a kind of method of rosin waste extraction processing

[0042] The part of turpentine (pine clear part) or tree pockets that have been cut for many years when felling pine wood is used as raw material. After slicing and rolling, the turpentine is recovered. After the turpentine recovery is completed, the wood chips are put into the rotary furnace, and a ton of wood chips is added with a medium boiling point solvent. Oil 2000Kg, coal ash 400Kg, urea 15Kg, benzophenone 0.5Kg. After the addition, seal the feed port of the rotary furnace, start the machine, rotate and stir, and heat to 80°C-100°C to react for about 2-2.5 hours. After finishing, open the discharge valve to discharge the medium-boiling solvent oil into the storage tank, and the remaining wood chips in the rotary furnace go through the screw extruder to squeeze and recover the medium-boiling solvent oil remaining in the wood chips to the storage tank . Finally, the wood chips containing a small...

Embodiment 2

[0045] Embodiment 2: a kind of method of rosin waste extraction processing

[0046] Get one ton of rosin waste wood residue, put it into a fully enclosed rotary furnace, then add 2000Kg of high boiling point solvent oil, 400Kg of coal ash, 15Kg of urea, and 0.5Kg of benzophenone. After the addition, seal the feed port of the rotary furnace, start the machine, rotate and stir, and heat to 80°C-100°C to react for about 2-2.5 hours. Then open the discharge valve to discharge the high boiling point solvent oil into the storage tank, and the waste residue remaining in the rotary furnace passes through the screw extruder to squeeze and recover the high boiling point solvent oil remaining in the waste residue into the storage tank. Then put the waste residue containing a small amount of high boiling point solvent oil into the pan dryer, and heat it to 200°C to recover the high boiling point solvent oil. Then send the dry wood slag that does not contain rosin to the workshop for prod...

Embodiment 3

[0049] Embodiment 3: a kind of method for extraction and processing of rosin waste

[0050] Include the following steps:

[0051] (1) rosin waste wood is put into a fully enclosed rotary furnace;

[0052] (2) adding the rosin waste extracting agent described in claim 6 in the rotary furnace; the rosin waste extracting agent is 2200 parts of high-boiling solvent naphtha, 450 parts of coal ash, 20 parts of urea, and 0.8 part of benzophenone;

[0053] (3) Seal the feed port of the rotary furnace, start the machine, rotate and stir, and heat to 80°C-100°C for about 2-2.5 hours;

[0054] (4) Open the discharge valve and solvent oil is discharged into the storage tank, and the waste residue remaining in the rotary furnace passes through the screw extruder again, and the solvent oil remaining in the waste residue is squeezed and recycled into the storage tank;

[0055] (5) put a small amount of solvent oil waste residue into the disc dryer, and heat to 200°C to recover the solvent ...

Abstract

The invention discloses a rosin waste extracting agent which is prepared from the following raw materials in parts by weight: 1500-2500 parts of solvent oil, 300-500 parts of coal ash, 10-25 parts of urea and 0.1-1.0 part of benzophenone. The invention also discloses a rosin waste extracting and processing method. According to the rosin waste extracting agent and the rosin waste extracting and processing method, various rosin plant castaway slag and waste leftover materials generated by processing of various woods are recycled as main production raw materials and special treatment is performed, so that rosin products are obtained.

Description

technical field [0001] The invention relates to a processing method of rosin, in particular to a rosin waste extractant and a method for extracting and processing rosin waste. Background technique [0002] Rosin products have a wide range of uses in the market, and are widely used in medicine, ink, papermaking, paint, coatings, printing and dyeing, and daily chemical products. As far as the ink industry is concerned, my country has more than 300 ink manufacturers, with an annual ink production capacity of 250,000 tons, second only to Japan and Germany. According to statistics from industry insiders: the consumption of printing inks in 2004 has exceeded 300,000 tons, and the consumption of printing inks in 2010 is nearly 450,000 tons. Experts predict that by 2020, my country's printing ink will reach more than 600,000 tons per year. With the rapid development of the domestic rosin deep processing industry, the demand for rosin products continues to increase. And rosin prod...
