Abstract
The invention discloses a polystyrene adhesive. Polystyrene foam reclaiming materials are classified, sordid parts thereof are clean and dried in advance and are respectively crushed into small bulks for later user. 28% of cyclohexanone and 72% of toluene are prepared to a mixed solvent, polystyrene foam fragments are added under the condition of stirring until is the polystyrene foam fragments are dissolved into sticky liquid. If the liquid is obtained by dissolving cleaned foam, filtering is further needed to remove impurities.
Description
Affiliated technical field:
The present invention relates to a kind of polystyrene tackiness agent, specifically refer to the polystyrene special-purpose adhesive made with the waste polystyrene foam, genus resource regeneration.
Background technology:
Annual depleted polystyrene foam is countless, becomes white pollution.And what use during the production of the polystyrene tackiness agent of traditional way is resin of industry.Replace resin of industry promptly to save social resources with the depleted polystyrene foam, reduce the pollution of plastic refuse again environment.
Summary of the invention:
The invention provides a kind of method, promptly replace resin of industry fully with the polystyrene foam reclaimed materials without the poly-stupid adhesive ethylene of resin of industry production.
Technical scheme:
Technical scheme of the present invention is: the polystyrene foam waste that reclaims after cleaning airing fragmentation, is dissolved in the mixed solvent of pimelinketone and toluene, removes impurity after filtration and be poly-stupid adhesive ethylene.
The invention has the beneficial effects as follows: recycle renewable resources, alleviate the refuse treatment burden, reduce industrial chemicals consumption such as resin of industry, reduce product cost.
Embodiment:
At first with the polystyrene foam classification of reclaiming, promptly separate clean and pollution is arranged, will there be the part of dust and dirt to clean airing; Clean then and through clean airing to be broken into fritter respectively standby.
By weight percentage, pimelinketone with 28% and the mixing of 72% toluene place in the big metal bucket of opening, prepare stirrer at a slow speed, under condition of stirring, add the polystyrene foam fragment, foam is soon by organic solvent dissolution, and liquid is progressively retrogradation also, is dissolved into liquid always and becomes thick and get final product.
If, can directly press the finished product packing with clean foam dissolved; If use, also should filter out remaining impurities and can be finished product packing through cleaning the foam dissolved of airing.
Claims (2)
1. polystyrene tackiness agent, the mixed solvent that is dissolved in pimelinketone, toluene by polystyrene foam forms, and it is characterized in that: utilize the depleted polystyrene foam to substitute resin of industry, save industrial chemicals, reduce the pollution of waste plastic to environment.
2. polystyrene tackiness agent according to claim 1, its feature also is: the described mixed solvent that is dissolved in pimelinketone, toluene by polystyrene foam forms, for utilizing very easily dissolved characteristic in ketones solvent of polystyrene foam, simplify the dissolving resin program, further reduced product cost.
