Abstract
The invention discloses an ultralight-colored polyterprene resin production process. The ultralight-colored polyterprene resin production process includes polymerizing, washing and distilling, and turpentine oil and catalyst of alchlor are polymerized in a reactor during the polymerizing procedure. The ultralight-colored polyterprene resin production process is characterized in that 0.2% by weight of hindered phenol oxidation inhibitor and 0.1 % by weight of decolorizer are added into a polymerized mixed product which is washed during the distilling procedure. Since the core technology at international advanced level is combined with the antioxidant decolorizer and the hindered phenol oxidation inhibitor, the product can be decolored effectively, and mother liquid in color luster ranging from 7# to 8# can be decolored into the product in color luster of 1#. Besides, the filtering procedures are added before and after the washing procedure respectively, so that aluminum dross and impurities can be separated more thoroughly, separation rate can be up to 98% or above. Further, ions, low-boiling-point components and by-products can be separated completely by the aid of precise distilling equipment integrating with the optimum process, odor of products is lightened, and pollution to the environment is reduced.
Description
Technical field
The present invention relates to a kind of production technique of terpine resin.
Background technology
Terpine resin is processed by natural turps, has superperformances such as transparent, nontoxic, neutral, electrical insulating property, hydrophobic, non-crystallizable, the diluted alkaline of anti-diluted acid the, heat-resisting, fast light, anti-aging and bonding force be strong.And various synthetics are had good intermiscibility, be soluble in aromatic hydrocarbon and vegetables oil.Terpine resin is a kind of good tackifier, and thickening property is superior to rosin and Abietyl modified thing and petroleum resin etc.; It also is the modifying agent of hot melt material, is widely used in the industry such as rubber, plastics, printing ink, coating, tackiness agent, pressure sensitive adhesive, cable, color printing, paint, packing, slushing oil, chewing gum.The main raw material of producing terpine resin is a turps; Turps is a kind of terpene mixture; It is mainly formed is firpene, and wherein α-Pai Xi and beta-pinene reach about 90%, has the particular chemical activity; Be a kind of excellent solvent, be the important source material of coating, SYNTHETIC CAMPHOR DAB 6, synthetic perfume, Terpineol 350, medicine industry, beneficiation reagent and other organic syntheses industry.
The existing production sequence and the technical process of terpine resin do; Raffinate after earlier turps being carried out rectifying and removes rectifying; Add solvent toluene and catalyzer again in the turps after rectifying; Carry out water wash procedures at turps and solvent toluene reaction back adding hot water; Obtain i.e. 2～3 the molecular firpene oligopolymer of firpene of liquid resin with distilling once more behind the refuse that produces in the catalyzer flush away and the reaction process of draining, just made terpine resin after the toluene that simultaneously liquid resin is included reclaims.Adopted this mode and made terpine resin and have following problem, one of which, during rectifying effectively group dicyclopentadiene alkene and also contain 5% α-Pai Xi and beta-pinene in the raffinate all in raffinate.Make active principle loss 3～5%, and energy consumption is big; Its two, during distillation, former technology is adding assistant not, the product color of producing is dark! ≧ 4#), iodine number high (45～75), poor heat stability (deepening 3# in following 4 hours) at 180 ℃; Its three, the original mother liquor after the original production process polymerization is not filtered, the aluminium slag is many, following operation washing difficulty also is a simple filtration after the washing, has influenced the quality of product.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the invention is to provide the production technique that can improve the ultra light terpine resin that produces quality.
To achieve these goals, the technical scheme of the present invention's employing is:
The production technique of ultra light terpine resin; Its operation comprises polymerization-washing-distillation; Wherein, in the polymerization process, turps and toluene, catalyzer aluminum chloride are carried out polyreaction in reaction kettle; It is characterized in that: in the said distillation process, the adding weight part is 0.2% Hinered phenols antioxidant and 0.1% discoloring agent in the polyreaction mix products after washing.
Set up the filtration operation respectively before the said washing step with behind the washing step.
The temperature of the water that said washing step is used is controlled at 80～100 ℃.
In the said polymerization process, the weight ratio of turps, toluene, aluminum chloride is 100: 100: 6.5.
Beneficial effect of the present invention: owing to adopt compound antioxygen discoloring agent of core technology and the Hinered phenols antioxidant with international most advanced level, product is effectively decoloured, can be 7#～8# mother liquor decolouring becoming 1# product with color and luster; Owing to before washing step He behind the washing step, set up the filtration operation respectively, isolating cleaner to aluminium slag, impurity, separation rate reaches more than 98%; In addition, adopt the accurate comprehensive optimised process of distillation plant to separate ion, low boiling component and sub product fully, reduced product odour, reduce environmental pollution.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further detailed description.
Fig. 1 is technological process of production figure of the present invention.
Embodiment
As shown in Figure 1, the production technique of ultra light terpine resin, its operation comprises polymerization-washing-distillation; Wherein, In the polymerization process, turps and toluene, catalyzer aluminum chloride are carried out polyreaction in reaction kettle, the weight ratio of turps, toluene, aluminum chloride is 100: 80: 6.5; It is characterized in that: in the said distillation process, the adding weight part is 0.2% Hinered phenols antioxidant and 0.1% discoloring agent in the polyreaction mix products after washing.
Set up the filtration operation respectively before the said washing step with behind the washing step.
The temperature of the water that said washing step is used is controlled at 70～100 ℃.
The above is a preferred implementation of the present invention, can not limit the present invention's interest field certainly with this.Should be pointed out that for those skilled in the art, technical scheme of the present invention is made amendment or is equal to replacement, do not break away from protection scope of the present invention.
