Abstract
The invention relates to the technical field of recycle of waste plastic and discloses a surface paint cleaning agent for waste plastic and a preparation method thereof. The surface paint cleaning agent is prepared from the following raw materials in percentage by weight: 10-18% of triethanolamine, 10-18% of sulfur-containing organic matters, 7-15% of an ethoxylated alkyl guanidine-amine complex, 10-18% of sodium silicate, 5-12% of sodium tripolyphosphate, 5-9% of potassium hydroxide, 1-5% of a butyl cellosolve, 1-3% of an accelerant, 1-3% of a thickener and the balance of water. According to the surface paint cleaning agent provided by the invention, triethanolamine and sulfur-containing organic matters replace alkyl chloride in the conventional paint remover as a main solvent, so that the surface paint cleaning agent is less in damage to a human body and environment, does not damage the matrix of the waste plastic, is low in boiling point, does not volatize and the cost is lowered. The surface paint cleaning agent for waste plastic provided by the invention is good in cleaning performance, thorough in paint cleaning, low in cost, less in environmental pollution and convenient to use.
Description
Technical field
The present invention relates to waste plastics recovery reutilization technology field, refer more particularly to a kind of plastic waste surface paint clean-out system and preparation method thereof.
Background technology
Waste material in food pack, plastic sheeting for farm use, woven bag, beverage bottle, plastic tub, bucket, toy, old sandals, household appliances shell and plastics processing process etc., the environment that the white pollution that a large amount of wastes forms is directly threatening the mankind to depend on for existence.Technics of reclaim of plastic waste is utilized the measure as a save energy, protection of the environment, just day by day comes into one's own, and especially developed country's work starting early, has been received obvious benefit.Prospective oil is fewer and feweri, and reprocessed plastic(s) also mean oil regeneration.Utilize plastic waste melt pelletization, can alleviate plastic raw materials imbalance between supply and demand, can save in a large number again the foreign exchange of national imported crude oil.In addition, due to most plastics non-degradables, accumulate over a long period, can cause serious white pollution, destroy the ecotope of the earth, and plastics reuse can pollution remission problem.Waste or used plastics is processed into after particle, still has good integrated materials performance, can meet the technical requirementss such as blown film, wire drawing, trombone slide, injection moulding, extrusion profile, is widely used in the production of plastics.
After technics of reclaim of plastic waste, adhere to a large amount of paint above, if these paint are not effectively cleaned, directly granulation not only makes regenerated granule class rudimentary, but also easily causes ageing of plastics, recyclability to reduce, and the product appearance of making is attractive in appearance not, work-ing life is short, of poor quality.Waste plastics recovery reutilization technology is ripe not enough at present, a large amount of plastic waste is also for re-using again, the ununified clean-out system painting for plastic waste surface specially, and paint remover in the market is not mostly suitable for the cleaning of plastic waste, and these paint removers are larger to the injury of plastic waste matrix, environmental pollution is also larger.
