Description
Technical field
The invention belongs to packaging material field, be specifically related to a kind of cosmetics plastic package material and preparation method thereof.
Background technology
Various in style, the Various Functions of cosmetics, but from the point of view of the adaptability with regard to its formalness and packaging, majority is liquid
Body, emulsion body or paste, do not possess the outward appearance of distinctness, it is necessary to by exquisite, unique package design, just can show it
Body characteristic, than metal, plastic and glass is the current main cosmetic package container material used.
Although cosmetic packing market one is taken as the leading factor to glass, but the multiformity of plastics and plasticity make plastics become
The most popular packing materials.And the resistance to impact of vial fill cost poor, frangible is high, processing and forming is more complicated etc. also
Limit the application of vial.Along with constantly clearing out the old and bringing forth the new of New Products, plastic containers achieve the most only glass
The transparent characteristic just having so that plastic is taken the course of its own on cosmetic packing market.Plastic be use plastics be main
Want the general designation of the articles for daily use of Raw material processing, industrial goods.2015, it is contemplated that plastic total output can reach 50,000,000
Ton.
The material of plastic bottle is usually PP (polypropylene), PE (polyethylene), K material, AS, ABS, acryl, PET (polyester)
Deng.PET material is environment-friendly materials, has high barrier, light weight, the most broken characteristic, chemically-resistant resistance, and the transparency is extremely strong, can do
Become pearly-lustre, coloured, magnetic is white, transparent, dress curry water in terms of be widely used.But, the easy static electrification of plastic containers existence, surface
Easily pollution, Litter can cause the problems such as environmental pollution, recycling are more difficult to be to can not be ignored and need solution badly.
Additionally, the use cycle of cosmetics is the longest, during Reusability, vessel surface often produces antibacterial
Multiplying, affect the healthy of user, exploitation antimicrobial plastic bottle is also a kind of development trend.Such as Publication No.
A kind of antibiotic plastic of the disclosure of the invention of CN104277374A, consists of the following composition: 55 parts of polrvinyl chloride, 1 by weight
～2 parts of phenyl silicone oil, 2～3 parts of aniline, 1～2 part of vinyltrimethoxy silane, 4～5 parts of calcium zinc salts, 2～3 parts of titanate esters, 1
～2 parts of glyceryl monostearates, 5～6 parts of methyl propanediol, 1～2 part of isomery ten polyoxyethylenated alcohol.And for example, Publication No.
The invention of CN104479286A relates to a kind of antibiotic plastic, is prepared by the raw materials in: plastic substrate 300-500 part,
Interface coupling agent 10-20 part, toughener 10-20 part, dispersed lubricant 1-10 part, antioxidant 10-30 part, releasing agent 0.5-3
Part and antibacterial 0.01-0.06 part, antibacterial uses 1-ethyl-4-[(4-methyl isophthalic acid-piperazinyl) methyl]-2-[(2,6-dichloros
Phenyl) sulfidomethyl]-5-hydroxyl-6-bromo-1H-indole-3-carboxylic acid's ethyl ester dihydrochloride, it is clear that this type of invention cannot be used for
Cosmetic package field.
Summary of the invention
The problems referred to above existed for prior art and defect, it is desirable to provide a kind of cosmetics plastics package material
Material, makes this material have antibacterial, antistatic property, to meet the demand of Plastics Development.
For realizing the purpose of the present invention, inventor provides following technical scheme:
