Abstract
The invention relates to a reusing treatment immersion cleaning agent for a PET bottle flake. The reusing treatment immersion cleaning agent is prepared from the following raw materials in parts by weight: 10-25 parts of a compound surfactant, 1-5 parts of a chelating agent, 5-15 parts of a buffering agent, 1-5 parts of an expanding agent, 10-25 parts of a saponifier and 40-80 parts of a filler. Compared with the prior art, by adopting the surfactant compounded by surfactants with the emulsion dispersion property and the seepage property, the reusing treatment immersion cleaning agent has the strengthened seepage property and is capable of easily seeping into capillary pores of the bottle flake to remove pollutants. As for removing pollutants in the capillary pores with hard surfaces, the mechanical force is useless, and sufficient seepage time is needed, so that the formula needs to be operated in a static impregnation mode. When being used, the impregnation time of the PET bottle flake is generally 8-15 minutes, and the impregnation time of an oil bottle flake which is severely polluted is 20-35 minutes.
Description
Technical field
The present invention relates to a kind of lotion, especially relate to a kind of PET bottle sheet recycling process lotion.
Background technology
The cleaning of recycling PET bottle or other plastics is the wash characteristics belonging to " crust ", and the polarity that is combined with between pollutent and crust adheres to, sticks together the several types such as adhesion, pore infiltration and plated film attachment.Because the characteristic of product and material, the more unmanageable form of poluttants of recycled PET bottles mostly occur stick together adhesion and pore permeate two kinds.
Stick together use glue the remaining on PET material surface adhering to the present adhesive type label of multilist, in practice, the kind of label glue can reach tens kinds, and therefore the removal efficiency of all kinds of glue kind is widely different.Cull retains in the course of processing of PET regenerative raw materials and subsequent applications, the comparatively leading cracking of PET of most colloid, produces complicated chemical composition, not only upsets the production efficiency of following process, and have a strong impact on the quality of PET subsequent product.At the regenerative PET of high quality applications scope, the quality demarcation that its cull retains is located between 5 ~ 15ppm.
Pore infiltration adheres to more intuitively to be discovered, surface capillary hole careful small be the characteristic of PET material, this is also same material terylene scrim easy dyeing characteristic not easy to fade.In the occasion of PET bottle recycling, the main source of pore osmosis pollution is that liquid packaged by PET bottle produces.If the component containing subset in packed liq, all can infiltrate pet sheet face pore after being installed in for some time.Affect the factor of regenerative PET chip mass, do not lie in infiltrate total amount number, but be to infiltrate the kind of material.Polymer is that in the material that possible infiltrate PET pore, the most difficult removal also affects most regenerative PET quality.The representational product of most is exactly edible oil, and the recycling of edible oil PET bottle cannot become the raw material of high additive value product all the time, can only be applied at most in the thicker common short fiber of low order.In addition in recent years, the downstream application of regenerative PET oneself be generalized to extreme bottle to bottle (Bottle to Bottle-is reduced to food grade PET bottle with the regenerative PET bottle material) stage, regenerative PET quality required in this field has been not the foreign matter content that naked eyes can be differentiated, the more important thing is the objectionable impurities focusing on and may infiltrate in the pore of pet sheet face.
Under the background of above-mentioned two existing difficult problems, domestic even external existing correlation technique all cannot with comprehensively, effectively and meet environmental protection, the method for economic principle reaches the object of dealing with problems.Below sketch art methods:
1. wash with the alkali lye of single high density, PET material, for a long time under highly basic effect, can produce splitting action, so that characteristic reduces, because the kind of cull is complicated, so heavy alkali not can effectively be removed all glue, for the pollutent in pore without any scavenging(action).
2. wash with commercially available industrial cleaners, effect comparatively may be better than item, but general commercially available composition there is no and fills a prescription targetedly, and washing effect cannot reach target, and many containing the ninth of the ten Heavenly Stems phenol system and tripoly phosphate sodium STPP etc. to environment sensitive or unfriendly composition.
3. with the mechanical force of high strength friction pet sheet face, the means on worn material top layer are utilized to reach the object removing pollutent, removal for cull can reach the effect of certain degree, but PET bottle sheet the flat surface of irregularity, so still have dead angle to remove, to pore cleaning also without effect.And the consume of this mode to power, work material and physical construction wears down greatly.
4. wash with the method for high-temperature boiling, under high temperature (lower than water boiling point 100 DEG C) condition, part cull (thermally melting glue) has ruckbildung and is easy to depart from, but also not all cull is all suitable for this principle, and this method does not have help to pore cleaning.The heat energy that the mode demand of high-temperature boiling is a large amount of, because of the characteristic of technique, heat energy is recycle not easily, causes very large waste.
5., with Organic chemical solvents washing, this is the method the most easily causing work peace accident and environmental pollution, and may need preparation 2 ~ 3 kinds of different solvents for different culls, processing condition relative complex.Already present pore is polluted to the possibility having removing, but solvent itself cause secondary pollution again, and not easily to remove.
Comprehensive aforesaid method merges use, only has the factor of more magnifies shortcomings, still cannot reach the effect of demand.
Summary of the invention
Object of the present invention is exactly provide a kind of to overcome defect that above-mentioned prior art exists thoroughly to remove pet sheet face pore remains, finished product high bake is non-yellowing PET bottle sheet recycling process lotion.
Object of the present invention can be achieved through the following technical solutions:
A kind of PET bottle sheet recycling process lotion, is mixed by the raw material of following component and weight part:
As preferably, described lotion is mixed by the raw material of following component and weight part:
Described tensio-active agent is selected from the composite of emulsion dispersion property class tensio-active agent and Penetration Signature class tensio-active agent, and the composite weight ratio of emulsion dispersion property class tensio-active agent and Penetration Signature class tensio-active agent is 1:1-2:5.
Described emulsion dispersion property class tensio-active agent comprises: iso-octyl Soxylat A 25-7, octadecane alcohol radical Soxylat A 25-7, different tridecanol polyoxyethylene ether, polyoxyethylene oleic acid ester, glycerin polyoxyethylene ether polyoxypropylene ether fatty acid ester, alkylbenzene sulfonate, N-Methyl fatty amide group taurate or Sodium dodecylbenzene sulfonate;
Described Penetration Signature class tensio-active agent comprises: alkyl sodium sulfonate, sodium alkyl benzene sulfonate, alkyl sulfuric ester sodium, Seconary Alkane Sulphonate Sodium, secondary alkyl sulphate sodium, fatty alcohol-polyoxyethylene ether phosphoric acid ester, sodium alkyl naphthalene sulfonate, succsinic acid alkyl ester sulfonate sodium or α mono-sodium olefin sulfonate.
Described sequestrant is selected from one or more in disodium edta, sodium polyacrylate or 4A zeolite.
Described buffer reagent is selected from one or more in water glass, sodium-acetate, Sodium Tetraborate or Trisodium Citrate.
