Abstract
The invention discloses polyvinyl chloride adhesive. The polyvinyl chloride adhesive is prepared by the following steps: classifying the reclaimed polystyrene foam, cleaning and airing the dirty part and breaking into small pieces for later use; mixing 52% cyclohexanone and 48% dimethyl benzene to obtain mixed solvent; and adding the polystyrene foam pieces with stirring for dissolution until the liquid becomes viscous. If the cleaned foam is dissolved, impurities need to be filtered and removed.
Description
Affiliated technical field:
The present invention relates to a kind of polyvinyl chloride tackiness agent, specifically refer to the polyvinyl chloride 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 polyvinyl chloride tackiness agent of traditional way is resin of industry, replaces resin-oatmeal promptly to save social resources with the depleted polystyrene foam, reduces the pollution of plastic refuse to environment again.
Summary of the invention:
The invention provides a kind of method, promptly replace resin of industry fully with the polystyrene foam reclaimed materials without resin of industry production polyvinyl chloride tackiness agent.
Technical scheme:
Technical scheme of the present invention is: the polystyrene foam waste that reclaims after the cleaning airing is pulverized, is dissolved in the mixed solvent of pimelinketone and dimethylbenzene, removes impurity after filtration and be the polyvinyl chloride tackiness agent.
The invention has the beneficial effects as follows: recycle renewable resources, alleviate the refuse treatment burden, reduce industrial chemicals consumption such as resin-oatmeal, 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 52% and the mixing of 48% dimethylbenzene 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, liquid is progressively retrogradation also, is dissolved into liquid always and becomes thick and get final product.
If, can directly pack with clean foam dissolved; If use, also should can be finished product packing through leaching remaining impurities through cleaning the foam dissolved of airing.
Claims (2)
1. polyvinyl chloride tackiness agent, the mixed solvent that is dissolved in pimelinketone, dimethylbenzene 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. polyvinyl chloride tackiness agent according to claim 1, its feature also is: the described mixed solvent that is dissolved in pimelinketone, dimethylbenzene 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.
