Abstract
The method of present invention processing waste polystyrene resin foamed material, first polystyrene resin foamed material is crushed, then broken polystyrene resin foamed material is placed in a container, tangerine oil is added in the container, the quality of the tangerine oil is 4~8 times of polystyrene resin foamed material quality, it heats while stirring, heating temperature is 30~80 DEG C, reaction time is 3~10 hours, decompression or steam distillation are carried out after dissolution completely again, solvent is steamed, remains as resin, is recycled.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 uses this natural solvent of tangerine oil, foamed material is dissolved, then boiling off solvent recovery resin, generative foaming material is made in foaming again, can be used as general packaging material.Therefore, tangerine oil is used to recycle white garbage by the present invention, nontoxic, harmless.
Description
Technical field
It is discarded poly- that the present invention relates to chemical field more particularly to a kind of polystyrene resin foamed material, especially processing
The method of styrene resin foamed material.
Background technique
China abounds with citrus, and in addition to a part is directly edible, a large amount of citrus will be processed into can or beverage etc. and add
Chemical product.So the application of orange peel is a very important project, taken out at present using squeezing method, steam distillation, solvent
It mentions, the methods of supercritical extract extracts tangerine oil from orange peel and is widely used.Ingredient and composition to tangerine oil is existing
Many research workers write text and reported.The tangerine oil produced at present is mainly used for making fragrance, household cleaners and medical work
Industry.
The foamed material of polystyrene resin is widely used, and the processing with waste later is one highly important
Environmental protection subject.In the prior art, it is discarded again after being dissolved using solvent, but solvent cannot be completely dissolved polystyrene resin
Foamed, only foamed material reduces volume.
Summary of the invention
The purpose of the present invention is to provide the method for processing waste polystyrene resin foamed material, this recycling
The method of processing polystyrene resin foamed material will solve polystyrene resin foamed material pollution environment in the prior art
The technical issues of.
The method that the present invention handles waste polystyrene resin foamed material, first breaks polystyrene resin foamed material
It is broken, then broken polystyrene resin foamed material is placed in a container, citrus is added in the container
Oil, the quality of the tangerine oil are 4~8 times of polystyrene resin foamed material quality, are heated while stirring, heating temperature
It is 30~80 DEG C, the reaction time is 3~10 hours, carries out decompression or steam distillation after dissolution completely again, steams solvent, residual
It is left resin, is recycled.
Further, absolute alcohol, the body of the absolute alcohol and tangerine oil are also added in the tangerine oil
Product is than being 0.01~0.1:1.
Further, a cleaning is further included the steps that after the polystyrene resin foamed material is broken.
Tangerine oil is a kind of natural, green solvent, and the solubility property of tangerine oil is very good, close to benzene class aromatic series
Compound.The present invention uses this natural solvent of tangerine oil, and foamed material is dissolved, solvent recovery resin is then boiled off and sends out again
Generative foaming material is made in the type of soaking, and can be used as general packaging material.
The present invention is compared with prior art, and technological progress is significant.Since tangerine oil is natural solvent, so whole
It is discharged in a removal process without pernicious gas.If discarded material to be processed sandwiching without rubbish, removal process theoretically may be used
It is considered zero-emission.Therefore, tangerine oil is used to recycle white garbage by the present invention, nontoxic, harmless.
Specific embodiment
The method that the present invention handles waste polystyrene resin foamed material, first breaks polystyrene resin foamed material
It is broken, then broken polystyrene resin foamed material is placed in a container, citrus is added in the container
Oil, the quality of the tangerine oil are 4~8 times of polystyrene resin foamed material quality, are heated while stirring, heating temperature
It is 30~80 DEG C, the reaction time is 3~10 hours, carries out decompression or steam distillation after dissolution completely again, steams solvent, residual
It is left resin, is recycled.
Further, absolute alcohol, the body of the absolute alcohol and tangerine oil are also added in the tangerine oil
Product is than being 0.01~0.1:1.
Further, a cleaning is further included the steps that after the polystyrene resin foamed material is broken.
