Description
Technical field
The present invention relates to a kind of technical field of plastic package, specifically a kind of cleaning agent for ink printed on surface of plastic and system thereof
Preparation Method.
Background technology
Along with the progress of China's economic society, China Plastics Industry quickly grows.Plastic yield is opened by reform
Put 1,040,000 tons of the initial stage, develop into current 36,000,000 ton, wherein five big product (PE/PP/PVC/PS/ABS) 34,000,000 tons,
1,200,000 tons of engineering plastics (PBT/PC/POM/PMMA etc.), polyester (PET) 800,000 tons (bottle level 650,000 tons, BOPET 150,000 tons).
Within 2005, China produces the plastic about 8,000,000 tons for packaging, agricultural film 1,300,000 tons altogether.Making of a large amount of plastic product
With, also bring serious environmental issue to Chinese society.Owing to plastic nature is stable, difficult degradation, can make if discarded
Become environmental pollution.Along with the reinforcement of people's environmental consciousness, the day by day exhausted of petroleum resources and the enforcement of the strategy of sustainable development,
The recycling of plastic has become as the hot issue of Chinese society.And the cleaning of ink printed on surface of plastic is removed,
Through becoming the inevitable technique of recycled plastic high value added utilization, there is important economic and social benefit.
The most conventional detergent for ink is broadly divided into two big classes: a class is vapour, kerosene.Vapour, kerosene are that a kind of wide spectrum has
Machine thing solvent, less expensive, it is adaptable to a lot of industries.Overwhelming majority printing enterprise is still using vapour, kerosene to make in a large number
Detergent for ink.But gasoline, kerosene there is also following shortcomings: first is safety problem.Vapour oil flash only has twenties
Degree, if the ventilation equipment in printing Factory Building is bad, it is easy to situation of causing danger.Even if the air circulation in Factory Building is very well,
Will not cause danger in workshop, but after the vapour of cleaned ink, kerosene are discharged away, in the season that outdoor temperature is higher
In, equally exist the danger of blast.Second is pollution problem.Vapour, kerosene, as a kind of organic solvent, itself have certain
Toxicity.Owing to vapour oil volatility is very big, even if the well-ventilated in workshop, workman sucks a certain amount of oil more or less
Gas.Meanwhile, workman is when being carried out operation, and other positions of hands or health can touch vapour, kerosene unavoidably.The gasoline sucked
Human body all can be caused certain injury by oil gas and the vapour, the kerosene that touch.Long-term so, the healthy of workman can be caused
Damage in various degree.If the 3rd be by kerosene, gasoline be used as ink printed on surface of plastic abluent, due to kerosene, gasoline
Solvability relatively strong, often in addition to dissolving ink, also can dissolve plastic basis material simultaneously, not reach the purpose of recycled plastic.
Summary of the invention
It is an object of the invention to provide a kind of cleaning agent for ink printed on surface of plastic and preparation method thereof, above-mentioned to solve
The problem proposed in background technology.
For achieving the above object, the present invention provides following technical scheme:
