Abstract
The invention relates to a method for recovering a polystyrene resin foamed material, which comprises the following steps: crushing the polystyrene resin foamed material, putting the crushed polystyrene resin foamed material in a container, adding orange oil (which is 5-10 times by mass of the polystyrene resin foamed material) into the container, heating while stirring, reacting at 30-80 DEG C for 3-10 hours until the polystyrene resin foamed material is completely dissolved, carrying out reduced pressure or steam distillation to remove the solvent and leave the resin, and recovering the resin. The orange oil is a natural green solvent with excellent solubility, and is approximate to benzene aromatic compounds. The natural solvent orange oil is utilized to dissolve the foamed material, the solvent is distilled off to recover the resin, and the recovered resin is foamed and molded to prepare the regenerated foamed material which can be used as a common packaging material. Therefore, when being used for recovering white garbage, the orange oil is nontoxic and harmless.
Description
Technical field:
The present invention relates to chemical field, particularly relate to a kind of polystyrene resin foam material, particularly a kind of method recycling polystyrene resin foam material.
Background technology:
China abounds with oranges and tangerines, and except a part directly eats, a large amount of oranges and tangerines all will be processed into the converted products such as can or beverage.So the application of peel of Citrus reticulata Blanco is a very important problem, adopts the methods such as milling process, steam distillation, solvent extraction, supercritical extraction from peel of Citrus reticulata Blanco, extract tangerine oil at present and be widely used.The composition of tangerine oil was reported with composition existing a lot of research worker's work literary composition.The tangerine oil of current production is mainly used in making spices, household cleaners and medicine industry.
The foam material of polystyrene resin is widely used, and is a very important environmental protection subject with the process of waste later.In prior art, discard again after using solvent to be dissolved, but solvent can not the foamed of dissolved polystyrene resin completely, is that foam material reduces volume.
Summary of the invention:
The object of the present invention is to provide a kind of method recycling polystyrene resin foam material, the method for described this recycling polystyrene resin foam material will solve the technical problem of polystyrene resin foam material contaminate environment of the prior art.
A kind of method recycling polystyrene resin foam material of the present invention, first that polystyrene resin foam material is broken, then the polystyrene resin foam material after fragmentation is positioned in a container, tangerine oil is added in described container, the quality of described tangerine oil is 5 ~ 10 times of polystyrene resin foam material quality, heat while stirring, Heating temperature is 30 ~ 80 DEG C, reaction times is 3 ~ 10 hours, dissolve completely and carry out again reducing pressure or steam distillation, steam solvent, remain as resin, be recycled.
Further, in described tangerine oil, be also added with raw spirit, described raw spirit and the volume ratio of tangerine oil are 0.01 ~ 0.1:1.
Further, the step of a cleaning is also comprised after described polystyrene resin foam material fragmentation.
Tangerine oil is a kind of natural, green solvent, and the solubility property of tangerine oil is very good, close to benzene quasi-aromatic compound.The present invention adopts this natural solvent of tangerine oil, by foam material dissolve, then boil off solvent recuperation resin again foaming make generative foaming material, can be used as general wrapping material.
The present invention compares with prior art, and its technical progress is significant.Because tangerine oil is natural solvent, so discharge without obnoxious flavour in whole removal process.If discarded material to be processed sandwiching without rubbish, removal process can think zero release in theory.Therefore, tangerine oil is used for reclaiming white garbage by the present invention, nontoxic, harmless.
Embodiment:
A kind of method recycling polystyrene resin foam material of the present invention, first that polystyrene resin foam material is broken, then the polystyrene resin foam material after fragmentation is positioned in a container, tangerine oil is added in described container, the quality of described tangerine oil is 5 ~ 10 times of polystyrene resin foam material quality, heat while stirring, Heating temperature is 30 ~ 80 DEG C, reaction times is 3 ~ 10 hours, dissolve completely and carry out again reducing pressure or steam distillation, steam solvent, remain as resin, be recycled.
Further, in described tangerine oil, be also added with raw spirit, described raw spirit and the volume ratio of tangerine oil are 0.01 ~ 0.1:1.
Further, the step of a cleaning is also comprised after described polystyrene resin foam material fragmentation.
Claims (3)
1. one kind recycles the method for polystyrene resin foam material, it is characterized in that: first that polystyrene resin foam material is broken, then the polystyrene resin foam material after fragmentation is positioned in a container, tangerine oil is added in described container, the quality of described tangerine oil is 5 ~ 10 times of polystyrene resin foam material quality, heat while stirring, Heating temperature is 30 ~ 80 DEG C, reaction times is 3 ~ 10 hours, dissolve completely and carry out again reducing pressure or steam distillation, steam solvent, remain as resin, be recycled.
2. a kind of method recycling polystyrene resin foam material according to claim 1, is characterized in that: in described tangerine oil, be also added with raw spirit, and described raw spirit and the volume ratio of tangerine oil are 0.01 ~ 0.1:1.
3. a kind of method recycling polystyrene resin foam material according to claim 1, is characterized in that: the step also comprising a cleaning after described polystyrene resin foam material fragmentation.
