Abstract
The invention relates to a solvent and a formula of a scavenger for UV (ultraviolet) screen printing ink on the surface of a medical PP (polypropylene) saline bag, belonging to the technical field of chemical industry. The scavenger contains cyclohexanone which accounts for 15-90% of the volume of the scavenger and also contains a mixture of ethyl acetate and acetone, a mixture of isopropyl alcohol and alkylphenol polyoxyethylene ether compound or a mixture of Isopropanol and sodium dodecyl benzene sulfonate. After the scavenger is used, the UV screen printing ink on the surface of the medical PP saline bag can be effectively removed by infiltrating for a very short period of time and applying an external force, thus favoring the recycling of the medical PP saline bags.
Description
Technical field
The present invention relates to solvent and the formula of a kind of medical PP bag of saline surface UV ink for screen printing scavenging agent, belong to chemical technology field.
Background technology
The material of current most medical bag of saline mainly adopts PVC, but because existing certain toxicity and advocate in the world, the PVC monomer adopt nontoxic PP material as bag of saline, PP material bag of saline has progressively replaced PVC material bag of saline at present, starts to become the main flow in medical market.Relatively simple for the recycling of the bag of saline of PVC and PP material in the past, mainly adopt the mode of landfill and burning.Pass through also hard degradation of many decades even the subject matter that the former exists is macromolecular compound after landfill, this processing mode will certainly cause great pollution to environment such as soil on every side, waters, has not basically adopted at present.The latter is the way of recycling often adopted at present, but there are two problems in this mode: the one, because PVC and PP all belong to macromolecular organic compound, burn when insufficient and easily produce the carinogenicity waste gas such as CO, Dioxins, atmosphere, environment and people's health is produced to infringement greatly; The 2nd, the utilization ratio that produces heat during for PVC and PP burning is current or relatively low.Therefore, be badly in need of the new PVC of exploitation and the recovery technology of PP.
For the PVC preferably characteristics relative to the PP material of preparation medical grade, many manufacturers intend after the PVC of medical grade and PP processing, carrying out regeneration.The Major Difficulties of regeneration is to find a kind of suitable chemical solvents formula, can effectively remove the printing ink on bag of saline surface, thereby improves the purity of PVC and PP reclaimed materials.For the bag of saline of PVC material, current common way is to adopt certain density caustic soda soln that the PVC bag of saline is boiled to the printing ink that certain hour can be removed the bag of saline surface, can reach the purpose of recycling after granulation.But the bag of saline for the PP material, owing to having adopted the UV curing technology when the screen printing ink, make the macromolecular chain that forms printing ink connect and solidify fast, printing ink is very large with the attachment fastness of PP material, and single chemical solvents is difficult to remove the UV ink for screen printing of PP material surface as ethanol, gasoline etc.Therefore, find the UV ink for screen printing that compound chemical solvents and formula thereof remove the PP material surface, become the main bugbear of the regeneration that hinders the medical bag of saline of PP.
In sum, the chemical solvents and the formula thereof that lack at present a kind of UV ink for screen printing of effective removal PP material surface.
Summary of the invention
The purpose of this invention is to provide a kind of chemical solvents and formula thereof of removing efficiently, cheaply the UV ink for screen printing of PP material surface.
For solving the problems of the technologies described above, a kind of scavenging agent, it is the scavenging agent for medical PP bag of saline surface UV ink for screen printing, described scavenging agent contains and accounts for the pimelinketone that described scavenging agent volume percent is 15～90, also contains the mixture of mixture (OP-10) of mixture, Virahol and alkylphenol polyoxyethylene of ethyl acetate and acetone or the mixture of Virahol and Sodium dodecylbenzene sulfonate.
Volumetric mixture ratio 12～the 16:1 of ethyl acetate and acetone～2 in the mixture of the ethyl acetate described in the present invention and acetone.
In the mixture of the mixture of the Virahol described in the present invention and alkylphenol polyoxyethylene, the mixture volume ratio of mixture of Virahol and alkylphenol polyoxyethylene is 39:1.
In the mixture of the Virahol described in the present invention and Sodium dodecylbenzene sulfonate, the volumetric mixture ratio of Virahol and sodium laurylsulfonate is 39:1.
The volume percent of the pimelinketone described in the present invention is 80, the Virahol volume percent is 19.5, described Sodium dodecylbenzene sulfonate volume percent is 0.5,50%～75% of the volume of mixture that the volume of volume external adding water is whole pimelinketone, Virahol and Sodium dodecylbenzene sulfonate.
The invention has the beneficial effects as follows: adopt the chemical solvents of the present invention's configuration, infiltrate the very short time, add certain external force, can realize the effective removal to medical PP bag of saline surface UV ink for screen printing, be conducive to the recycling utilization of the medical bag of saline of PP.
Embodiment
Below in conjunction with embodiment, the invention will be further described, yet the present invention absolutely not only is confined to described embodiment.
