Description
Technical Field
The invention belongs to the technical field of degradable high polymer materials, and particularly relates to a double-layer packaging hose for paste cosmetics.
Background
The plastic is a petroleum product with extremely wide application range, and has the advantages of strong corrosion resistance, durability, water resistance, light weight, low cost, easy plasticity and the like; is widely applied to various fields. In the cosmetic field, the plastic package is used for more than 95% except for a small part of the glass container.
Cosmetic packaging materials are divided into a packaging hose, a hard packaging box and a packaging film. The packaging hose is a material directly used for containing cosmetics, plays a role in blocking and guaranteeing quality, and directly influences the storage and quality of the cosmetics.
At present, the cosmetic packaging material generally adopts PVC (polyethylene) as a main body; however, polyethylene has poor barrier properties; the biological degradation is impossible, the secondary use (abuse) is possibly caused, and certain potential safety hazards exist; incineration is generally adopted, so that on one hand, resources are wasted, and on the other hand, the environment is seriously polluted; is unfavorable for the green development of cosmetic packaging materials.
Polylactic acid (PLA) is the only transparent biodegradable material, and has good hot processing performance and biocompatibility; the PLA has wide application prospect, but has poor toughness due to high strength, so that the development of the PLA is limited to a certain extent; thus, there is a need to provide a degradable plastic package for the particular needs of cosmetic packages.
Disclosure of Invention
The invention provides a double-layer packaging hose for paste cosmetics, which is modified by various parts to meet the requirements of paste cosmetics.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a double-layer packaging hose for paste cosmetics comprises an outer layer packaging and an inner layer packaging;
the outer packaging comprises the following components in parts by mass:
the inner layer package comprises the following components in parts by mass:
the inner layer package comprises at least 60% of the total mass.
In particular, the particle size of the calcium carbonate is in the range of 20-100nm.
In particular, the PLA is a l-polylactic acid.
In particular, the organoclay is kaolin or/and montmorillonite.
The invention also provides a preparation method of the double-layer packaging hose for the paste cosmetics, which specifically comprises the following steps:
the preparation method of the outer package comprises the following steps: uniformly mixing the raw materials according to the proportion, and then melting, plasticizing and granulating in a double-screw extruder;
the preparation method of the inner layer package comprises the following steps: the raw materials are uniformly mixed according to the proportion, and then melted, plasticized and granulated in a double-screw extruder.
And (5) blowing the outer package and the inner package into films by adopting a coextrusion machine.
In the invention, the following components are added:
PLA (polylactic acid) refers to polylactic acid;
PLLA (Poly-L-lactic acid) refers to Poly-L-lactic acid;
PBAT (Poly (butylene glycol-co-terephthalate)) refers to a butylene adipate and butylene terephthalate copolymer;
PHBV (Polyhydroxybutyrate-co-valerate) refers to Polyhydroxybutyrate valerate copolyester;
PBO (Poly-p-phenylene benzobisoxazole) refers to Poly-p-phenylene benzobisoxazole fibers;
ADR-4300 refers to the Pasteur (BASF) chain extender ADR-4300.
The outer packaging of the invention mainly needs to have high elasticity, high transparency and high barrier property, and mainly serves to protect the inner packaging from abrasion and external pollution.
Therefore, the outer package of the invention takes highly transparent PLLA as a main body, and simultaneously adopts the poly (trimethylene carbonate) and the cinnamon essential oil as mechanical improvement and antibacterial components, so that the tensile strength and the elongation at break of the outer package can be greatly improved; meanwhile, since cosmetics are generally placed in a relatively humid space such as a bathroom, good antibacterial properties are required.
The D-lactic acid can reduce the ventilation quantity of PLLA and increase the barrier property of PLLA; triphenyl phosphate is used as a heat stabilizer; ADR-4300 is a good chain extender and is a good processing aid; meanwhile, the material also has a certain improvement effect on mechanical properties.
The inner package of the present invention is used as a direct contact content while it is necessary to print commodity information on the outer surface of the inner package, so that the main requirements of the inner package are antibacterial, barrier, printability and chemical stability.
Therefore, the inner package adopts PBAT and PHBV as main degradable materials, and simultaneously adds the paper sedge fiber to increase writability (printing) and antibacterial property, and simultaneously has good toughening and blocking effects. The three blends are used as main materials, and in order to enhance the antibacterial performance, calcium carbonate, polyhexamethylene guanidine hydrochloride and organoclay are added for compound antibacterial.
The Paper sedge fiber of the invention is Paper sedge Paper fiber (Paper) which is native to Egypt, the ignition point of the Paper sedge fiber is lower and is slightly higher than the melting temperature (Tm) of PHBV; however, the invention discovers that under the condition of uniform mixing, the paper sedge fiber still cannot burn under the premise of being higher than the ignition temperature, because the oxygen in the extruder is insufficient, and meanwhile, the air is difficult to contact under the blending mode, and in addition, the components such as calcium carbonate, organoclay and the like have better flame retardant performance under the condition, and the combustion of the components is prevented under the action of various reasons.
Meanwhile, the calcium carbonate is used as a filler, so that the mechanical property can be improved; the polyhexamethylene guanidine hydrochloride and the organoclay can also effectively reduce the air permeability and enhance the barrier property; PBO belongs to a coupling agent in the present invention for improving dispersibility between components.
The double-layer material prepared by the invention is biodegradable and environment-friendly; meanwhile, the antibacterial agent has good mechanical property, antibacterial property and chemical stability.
