Description
Technical field
The present invention relates to a kind of transparent anti-aging cups, belong to technical field of living goods.
Background technique
It is several to be generally divided into glass, plastics, ceramics etc. by material for cup, and glass, ceramic water cup are intolerant to falling, and plastics water
Cup is relatively durable, and moulding is changeable, therefore plastic cup occupies bigger market.Plastic cup is generally by polypropylene (abbreviation
PP), the materials such as polycarbonate (abbreviation PC) or polyethylene terephthalate (abbreviation PET) are made, wherein PET plastic cup one
As non-refractory, for maximum operation (service) temperature no more than 70 DEG C, wall of cup is relatively thin, is mainly used for packing soda, drinking water, fruit
Juice, ferment and tea beverage etc.；PC is a kind of material being widely used, and is especially chiefly used in manufacturing feeding bottle, Space cup etc., but because
Controversial always containing bisphenol-A (BPA), BPA will lead to endocrine disorder, threaten fetus and the health of children.Cancer and
Obesity caused by metabolic disturbance is recognized as related with this.European Union thinks that feeding bottle containing bisphenol-A can induce sex premature, from 2011
From on March 2, in, forbid the baby bottles for producing bisphenol-A containing chemical substance (BPA).Also prohibit and on June 1st, 2011 in China
Only bisphenol-A is for infant food container (such as feeding bottle) production and import.PC feeding bottle is quietly withdrawn from the market.And polypropylene without
Malicious, odorless, tasteless, quality is light, is one of kind most light in current all plastics, and polypropylene has good heat resistance,
Product can carry out disinfection sterilizing in 100 DEG C of temperatures above, and under conditions of not by external force, 150 DEG C also indeformable.Alternative PC and
PET is used to prepare transparent cup.
But polypropylene transparent performance is bad, oxidative resistance and radiation resistance are poor, relatively variable in the case where there is sunlight irradiation
Shape.Therefore needing to be modified polypropylene material processing or addition auxiliary agent overcomes these problems, to meet transparent cup use
Demand.
Currently, mainly improving polyacrylic crystal size and form by addition nucleating agent, to make polyacrylic
Bright performance increases, a kind of polypropylene material for transparent bottles as disclosed in Chinese patent (publication number: CN 102391585A), this is poly-
Propylene material improves the product transparency by introducing antioxidant and transparent agent, although the polypropylene material transparency is mentioned
Height, but because a large amount of additions of antioxidant, transparent agent and acid absorbent, seriously reduce the mechanical property of material, antioxygen
The property changed can not meet the application under outdoor sports and hot conditions.Chinese patent (publication number: CN102869719A) discloses
A kind of polypropylene vial, the patent by addition nucleating agent improve product mechanical property, although improve the impact property of product,
Rigid nature, but the transparency of product does not obtain substantive raising, the product transparency of acquisition is only 90% or so.
Summary of the invention
For existing polypropylene material be applied to cup light transmittance it is low, the problem of oxidative resistance and radiation resistance difference, this hair
It is bright to provide that a kind of transparency is good, ageing resistance is strong and mechanical property and excellent polypropylene material, be applied to cup, from beautiful and
Practical upper imparting cup more high transparency and ageing resistance.
Above-mentioned purpose of the present invention can be realized by the following technical scheme: a kind of transparent anti-aging cup, the water
Cup have it is circular opening, circular bottom of a cup and connection opening and bottom of a cup wall of cup, the cup it is straight via bottom of a cup from be open
It becomes larger, and is arranged on wall of cup in axial step shape；The cup is made of composite material, the composite material include with
The ingredient of lower parts by weight:
Polypropylene: 50-75 parts
Polymethyl methacrylate: 25-35 parts
High density polyethylene (HDPE): 6-18 parts
Modified Nano filling: 5-12 parts
Compatilizer: 5-15 parts
Transparent agent: 0.01-0.3 parts
Age resister: 0.02-0.3 parts

The composite material of the transparent anti-aging cup of the present invention is used in compounding poly-methyl methacrylate using polypropylene as matrix
Ester, high density polyethylene (HDPE), modified Nano filling effectively improve the light transmittance, ageing resistance and mechanical property of polypropylene material
Can, while also added compatilizer, transparent agent, age resister and each analog assistant, pass through the synergistic effect generated between each component
Further increase polypropylene material properties.
Polymethyl methacrylate (PMMA) has good mechanical property, tensile strength, bending strength and compression
Intensity etc. is significantly larger than other general-purpose plastics and makes because of the presence of the pending methyl group on the biggish side carbomethoxy of PMMA and alpha-carbon atom
The rigidity of polymer molecular chain increases, and causes PMMA hardness big.PMMA has very excellent optical property, as three kinds of skies
Between found the mixture of structure body, macroscopically belong to amorphous polymer, for rigid colourless transparent material, therefore transmissivity is high, can be with silicon
Glass compares favourably, and transmissivity is greater than 91%.And PMMA has good anti-aging property, open air that can be strong in ultraviolet light for a long time
It uses, sample passes through 4 years natural ageing tests, and quality is unchanged, and tensile strength, transmissivity are declined slightly, other physics
Performance does not almost change.Polypropylene is blended with PMMA, improves the interface between mixed system by the introducing of compatilizer and ties
Intensity is closed, realizes and has complementary advantages, obtained material can integrate polypropylene and PMMA excellent performance, can improve the power of product
Intensity is learned, while improving the surface hardness of product, increases the light transmittance and ageing resistance of product.Polypropylene and the optimal matter of PMMA
Amount compounding is than being (2-3): 1, material property within this range is more excellent.
High density polyethylene (HDPE) (HDPE) is blended with system, and PP and HDPE has obstruction to make between each other in crystallization in system
With HDPE has carried out insertion segmentation to PP spherocrystal, so that PP spherocrystal becomes lesser fragment, reaches the mesh of refinement PP spherocrystal
, to make the transparency of polypropylene material, shock resistance enhancing.
The partial size of nanoparticle is smaller, and surface energy with higher and Surface binding energy cause nanoparticle easily to be reunited,
Nanoparticle after reunion is unfavorable for the improvement of material mechanical performance, anti-aging property, therefore carries out at surface to nanoparticle
Reason is the key that prepare that mechanical property is good, the good polypropylene material of ageing resistance.The introducing of modified Nano filling can improve material
The mechanical property of material adds a small amount of nanoparticle and makes polypropylene spherocrystal particle tiny and uniform, plays to polypropylene material
The effect of activeness and quietness, and because of nanofiller, partial size is small, large specific surface area, activity are high, has bigger contact surface with polypropylene
Product is simultaneously more firm with substrate adhesive, when material is by external impacts, the physical three-dimensional network meeting of nanofiller and polypropylene formation
Play the role of stress concentration, absorbs impact energy to improve the impact resistance of material.The introducing of modified Nano filling can be effective
Improve the ageing resistance of material, on the one hand, nanofiller has suitable particle size range, therefore has stronger dissipate to ultraviolet light
Ability and function of shielding are penetrated, the ultraviolet part for being irradiated to material is shielded, delays material aging；On the other hand, nanometer is filled out
The quantum size effect of material not only makes it generate blue-shifted phenomenon to ultraviolet light, and existing with widthization to the absorption of various wavelength lights
As this makes nanofiller have certain absorbability to ultraviolet light, reduces ultraviolet break and changes.Virgin pp material accelerates through ultraviolet light
When being aged to 200h, 50% or more loss of tensile strength, and impact strength is only the 2/3 of initial value；It is exposed to the open air in ultraviolet light
When 700h, for loss of tensile strength close to 90%, impact strength damages half.After nano-filler modified, the mechanics of PP
Property retention rate increases substantially, and substantially increases the actual use value of PP material.Modified Nano filling adds in the present invention
Number keeps material property optimal, and the excessive nanofiller that is added will affect the transparency of material.
The transparent agent and age resister that composite material of the present invention introduces are filled out with polypropylene, PMMA, HDPE and modified Nano
