By polymerizeing a kind of thermoplastic resin obtained, nontoxic odorless, chemical stability is good, has excellent resistance to low temperature.Poly- second
Alkene has impact strength high, and toughness is preferable, is added to after being mixed with polypropylene in cup lid raw material, plays and improves cup lid impact strength
Effect.
Elastomer refers to that deformation is notable under weak stress, can be promptly restored to after stress relaxation close to original state and size
High molecular material, be divided into thermo-setting elastomer and thermoplastic elastomer (TPE).After elastomer is added in cup lid raw material, when cup lid stress
It deforms upon, elastic deformation occurs for cup lid after active force revocation, further increases the impact strength of cup lid, has reached cup lid impact
The effect of intensity height, good toughness.
The further setting of the present invention is：It counts in parts by weight, includes 60-80 parts of polypropylene, 20-30 parts of poly- second in raw material
Alkene, 10-25 part elastomer.
By using above-mentioned technical proposal, in the raw material of cup lid, including 60-80 parts of polypropylene, 20-30 parts of polyethylene, 10-
25 parts of elastomers.
The further setting of the present invention is：It counts in parts by weight, includes that 1-10 parts of whites are female in raw material.
By using above-mentioned technical proposal, color masterbatch is also known as Masterbatch, is a kind of colorant for high molecular material, white
Mother is white or albescent Masterbatch, is added in cup lid raw material for colouring, keeps cup lid color white or shallow white.
The further setting of the present invention is：The elastomer includes styrene analog thermoplastic elastomer, thermoplastic polyurethane
It is one or more in elastomer, olefin hydrocarbons thermoplasticity elastic body, thermoplastic polyamide elastomer.
By using above-mentioned technical proposal, styrene analog thermoplastic elastomer stability is good, acid and alkali-resistance.Thermoplastic polyurethane
Elastomer is also known as thermoplastic polyurethane rubber, has the excellent comprehensive performances such as high intensity, high tenacity, wear-resisting, oil resistant, is added to
In cup lid raw material, the wear-resisting property and chemical stability of cup lid are improved.Olefin hydrocarbons thermoplasticity elastic body includes olefines TPES, heat
Plasticity polyolefin, elastomer modified polypropylene, engineered polyolefin etc. have low weight and excellent processing performance.Polyamide heat
Thermoplastic elastic is made of high-melting-point crystallinity hard section polyamide and amorphism soft segment, since intramolecular includes hard section polyamides
Amine makes thermoplastic polyamide elastomer that there is excellent toughness, chemical resistance, wearability, thermoplastic polyamide elastomer to be added
Into cup lid raw material, the toughness, chemical resistance, wearability of cup lid are improved.
The further setting of the present invention is：Further include titanium dioxide nanofiber in cup lid raw material.
By using above-mentioned technical proposal, from the point of view of the fracture mechanics angle of material, the impact fracture and stretching of plastics are disconnected
Split be crack extension process.External force acts on material, since fault of construction or inhomogeneities cause stress concentration in material,
Form crazing.Crazing phenomenon is material under tensile stress effect, stress concentration occurs and generation office in the certain weak parts of material
The plastic deformation in portion and orientation, so that in occurring length on stress direction being 100 μm, width in material surface or internal vertical
10 μm or so, thickness the phenomenon that being 1 μm of fine groove.Material forms crazing and needs to consume big energy, these energy include
The surface work of viscoelastic work(, formation crazing hole when plastic work done, crazing when generating crazing extend, the chemistry of macromolecular chain fracture
Chain energy to failure etc..Further development forms crack to crazing under stress, and when external force continues effect, crack is further expanded
Greatly, the fracture of material is caused.
Include titanium dioxide nanofiber in the application cup lid raw material, titanium dioxide nanofiber is dispersed in cup lid raw material
Interior, titanium dioxide nanofiber diameter is smaller, is dispersed in cup lid raw material, can be preferable between other components in cup lid raw material
Ground combines.During cup lid after outer force effect by crazing is formed, the plastic work done etc. when not only needing to consume above-mentioned generation crazing
Energy, it is also necessary to overcome the interaction force between other components in titanium dioxide nanofiber and raw material, form the mistake of crazing
It needs to consume more energy in journey, plays and inhibit crazing phenomenon.After the crazing of cup lid forms crack, titanium dioxide nanofiber
It being dispersed in crack, plays cementation, inhibit the further expansion in crack, after external force cancels, cup lid restores original size,
Further increase the toughness of cup lid.
The further setting of the present invention is：Load has zinc sulfate on the titanium dioxide nanofiber.
It is inorganic matter that by using above-mentioned technical proposal, on titanium dioxide nanofiber, load, which has zinc sulfate, zinc sulfate, is born
After being loaded in titanium dioxide nanofiber, enhance the interaction between titanium dioxide nanofiber and cup lid inner macromolecule material
Power generates crazing after making cup lid stress and crack needs to consume more energy, further increases the toughness of cup lid.
After load has the titanium dioxide nanofiber of zinc sulfate to be dispersed in cup lid, in titanium dioxide nanofiber and cup lid
Macromolecule be completely embedded, interaction force is stronger, and cup lid will not soften or decompose when heated, improve the heat resistance of cup lid.Separately
Outside, titanium dioxide nanofiber is added in cup lid raw material, moreover it is possible to further increase the corrosion resistance of cup lid.
The further setting of the present invention is：It counts in parts by weight, includes 2-8 parts of titanium dioxide nanofibers in raw material.
Include 2-8 parts of titanium dioxide nanofibers in cup lid raw material by using above-mentioned technical proposal.
The further setting of the present invention is：It further include hydroxypropyl cellulose in raw material.
