This cheap, stable quality, it is safe and non-toxic, meet safe and healthy, suitable making cup shell.
Although above-mentioned plastic cup all has respective advantage and feature, but also still have several drawbacks, plastic cup
As the apparatus for holding the beverages such as water, tea, make tea, electuary when, can generally import hot water, it is more thin for some chamber walls
For disposal plastic cup, since it is by hot poor, the easy deformation of cup body after heated, and intensity is greatly reduced, and influences to make
With.Secondly, as drinking instrument, if having grown bacterium on cup body, and then sanitary condition is influenced, is finally harmful to health, if
Plastic cup can have antibacterial action, just be avoided that the above situation.
Invention content
In order to solve the above technical problem, the present invention provides a kind of high-temperature resistant antibacterial PET plastic cup, plastics of the invention
Cup, as primary raw material, has effects that high temperature resistant, antibacterial using modified PET, and heated rear cup body is not easy deformation, and stability is good,
And the growth of bacterium can also be inhibited, beneficial to health.The invention also discloses a kind of high-temperature resistant antibacterial PET plastic cups
Preparation method.The preparation method is simple, and production efficiency is high, and at low cost, plastic cup quality obtained is good, and product stability is high, fits
Together in large-scale production.
The specific technical solution of the present invention is：A kind of high-temperature resistant antibacterial PET plastic cup, by the raw material of following mass percent
It is made：
The modified PET of 85-95%,
The glass fibre of 3-7%,
The heat stabilizer of 1-5%,
The lubricant of 1-3%.
The present invention plastic cup primary raw material be PET, PET be highly crystalline polymer, smooth surface and have light
Pool, nontoxic, water absorption rate is low, and hardness is high, and easy to process, molding, the raw material be especially suitable for plastic cup.But PET is also deposited
Itself the shortcomings that, PET is intolerant to hot-water soak.Therefore for plastic cup, especially disposal plastic cup, in soaking beverage
When adding hot water in cup, cup body is easy heated and softens, deforms, and leads to strength reduction, seriously affects use.For this purpose,
The present invention compounds PET and glass fibre, heat stabilizer and lubricant, and glass fibre can not only effectively promote plastics
Heat resistance, and can also further promote the toughness of plastics.Heat stabilizer can prevent plastics by thermal oxide, decompose, with glass
Fiber, which acts synergistically, further increases the thermal stability of plastics.After above-mentioned compounding, disposable PET plastic cup is enabled to
Heated softening temperature is promoted to 100 DEG C or so by 60 DEG C, with boiling water temperature close, is convenient for actual use.
Wherein, the preparation method of the modified PET includes the following steps：
1) terephthalic acid (TPA) 1: 1.3-1.7 is mixed in molar ratio with ethylene glycol, is heated to 220- under the action of catalyst
260 DEG C of progress esterifications, reaction pressure 0.3-0.5MPa, reaction time 0.5-2h.
2) it is 15- that cellulose dissolution is obtained to mass fraction in 1- butyl, 3- methylene diacetate imidazolium ionic liquids
25% cellulose solution；The cellulose solution of its quality 10-20% is added into the reaction solution of step 1) and is stirred evenly；So
Polynary nitric acid metal salt solution is added dropwise into reaction solution with the speed of 20-30mL/min afterwards and is stirred evenly, is added dropwise rear quiet
Set 20-40min；The dripping quantity of polynary nitric acid metal salt solution is the 5-15% of step 1) reaction solution quality afterwards；During step 2)
Reaction temperature is 200-240 DEG C, reaction pressure 5000-400Pa, reaction time 1-2h.
3) reaction temperature is warming up to 260-280 DEG C, reaction pressure is adjusted to 100-400Pa, the reaction was continued 2-3h.
4) reaction product is taken out after reacting, modified PET is made after filtering, drying.
In addition, in order to make plastics that there are antibacterial functions, the present invention to have carried out modification to PET.In the above-mentioned methods, it walks
It is rapid 1) in it is existing terephthalic acid (TPA) and ethylene glycol are first subjected to pre-reaction, under special reaction condition, obtain molecular weight it is lower and
Molecule end has the performed polymer of hydroxyl.
In step 2), first cellulose solution is mixed with the reaction solution of step 1), polynary nitric acid metal salt is then added dropwise
Solution.Due to active higher group (especially cellulose) on PET performed polymers and cellulose, can with metal ion into
Row ion exchange, reaction, to the upper a variety of different metal ions of grafting.Different metal ions meets water due to price difference
Micro- magnetic field can be formed after heating, and under micro- magnetic fields, the antibacterial activity of metal ion has obtained significantly reinforcing, from
And plastics is made to be provided with outstanding antibacterial functions.And with it is traditional directly add antiseptic in the plastic the difference is that
The present invention is to graft on metal ion on PET and cellulose, and more preferably, there is no common antibacterials for dispersibility and stability
The case where additive is easy to be lost in from plastic substrate in long-time or after being heated, therefore antibiotic property is ensured.In addition,
The order of addition of each substance also has considered critical in this step, it is necessary to first mix cellulose solution with PET performed polymers, then side drop
It adds first nitric acid metal salt solution side and carries out polymerisation.Benefit, which is cellulose, can be interspersed in PET performed polymer systems, and fine
Reaction can be crosslinked again between dimension element, formed network, after PET performed polymers continue polymerization, enabled to cellulose mutual with PET
Envelope fully merges, and in grafting after metal ion, the dispersibility and stability of metal ion can also further increase.Metal from
Son is dispersed between plastic molecules, can be formed one layer uniform " metal ion protection network ", is realized in plastic cup
The sterilization of the beverages such as water.In conclusion with traditional compared with adding antiseptic again after PET polymerize, the present invention is when PET polymerize
Antimicrobial component just is added, there is better antibacterial effect, dispersibility and stability.In addition, cellulose can also be carried further
The toughness of high PET.
In step 3), continuing raising reaction temperature and vacuum degree, considered critical reaction condition can improve PET's
Reactivity reduces the generation of side reaction.
