Abstract
The invention belongs to daily chemical product manufacture field, and in particular to a kind of photocatalyst bristles, the bristle is by as follows into being grouped into：The resin raw material of the photocatalyst of 1.5 3 weight portions, 97 98.5 weight portions.After invention in these bristle materials to the photocatalyst with the 30nm of photocatalysis 5 is added into, after bristle filaments are made, tensile strength, bending strength are not all in, impact strength, than pure raw materials itself improves 325%, 106%, 89.8% respectively, and due to the photocatalysis of photocatalyst, bristle surface is set to produce the extremely strong free hydroxy of activity and superoxide anion, active oxygen of oxidability, with very strong photoredox function, make bristle itself that there is good antibacterial, sterilizing function.
Description
Technical field
The invention belongs to daily chemical product manufacture field, and in particular to a kind of photocatalyst bristles.
Background technology
Traditional bristles are generally the making of the fibers such as PP, PA, PE, PET, in our every day uses, due to often connecing
Water, food Disabled slags etc. are touched, bacteria breed can be formed in bristle.Mouth infection is easily caused when reusing.To healthy
Produce influence.
The content of the invention
Therefore, the technical problems to be solved by the invention are the bottleneck for overcoming prior art, so as to propose one kind itself
Toothbrush bristle with good antibacterial, sterilizing function.
In order to solve the above technical problems, the invention discloses a kind of photocatalyst bristles, the bristle is by as follows into packet
Into：The photocatalyst of 1.5-3 weight portions, the resin raw material of 97-98.5 weight portions.
Preferably, the photocatalyst is T iO2、ZrO2、ZnO、Fe2O3、SrTiO3、SiO2, platinum, Lao, Palladium, in gold, silver
It is a kind of.
Preferably, the resin raw material is PET or polyamide.
Preferably, the photocatalyst is the photocatalyst of 5-30nm.
Preferably, the photocatalyst is rutile-type photocatalyst or anatase titanium dioxide photocatalyst.
Preferably, the TiO2It is 1.5 weight portions.
It is more highly preferred to, the preparation method of the bristle is as follows：Weigh the photocatalyst of corresponding weight portion, add resin former material
Material, at a temperature of 260 DEG C, being extruded by extruder and being cooled down to obtain.
Above-mentioned technical proposal of the invention has advantages below compared to existing technology, and the invention of this formula is to these bristle materials
In be added into the photocatalyst with photocatalysis 5-30nm after, after bristle filaments are made, tensile strength, bending are not all in strong
Degree, impact strength, than pure raw materials 325%, 106%, 89.8% is itself improves respectively, importantly due to photocatalyst
Photocatalysis, makes bristle surface produce the extremely strong free hydroxy of activity and superoxide anion, active oxygen of oxidability, tool
There is very strong photoredox function, make bristle itself that there is good antibacterial, sterilizing function.Disinfection rate is 99.8%.
Specific embodiment
Present embodiment discloses a kind of photocatalyst bristles, the bristle is by as follows into being grouped into for embodiment 1：1.5 weight
The TiO of part2The PET of photocatalyst, 98 weight portions.
Preferably, the photocatalyst is the nano level photocatalysts of 20nm.The photocatalyst is rutile-type photocatalyst.
The preparation method of the bristle is as follows：Weigh the photocatalyst of corresponding weight portion, add PET,
The hot-extrudable shaping at 260 DEG C.
Present embodiment discloses a kind of photocatalyst bristles, the bristle is by as follows into being grouped into for embodiment 2：2 weight portions
ZrO2The polyamide of photocatalyst, 97 weight portions.
The photocatalyst is the nano level photocatalysts of 30nm.The photocatalyst is rutile-type photocatalyst.
The preparation method of the bristle is as follows：Weigh the photocatalyst of corresponding weight portion, resin raw material added, at 260 DEG C
Under hot-extrudable shaping.
Present embodiment discloses a kind of photocatalyst bristles, the bristle is by as follows into being grouped into for embodiment 3：3 weight portions
ZnO photocatalysts, the PET of 98.5 weight portions.
The photocatalyst is TiO2、ZrO2、Fe2O3、SrTiO3、SiO2, platinum, Lao, Palladium, any one in gold, silver.
The photocatalyst is the nano level photocatalysts of 5nm.The photocatalyst is rutile-type photocatalyst.
The preparation method of the bristle is as follows：Weigh the photocatalyst of corresponding weight portion, resin raw material added, at 260 DEG C
Under hot-extrudable shaping.
Bristle principle described in embodiment 1-3：Photocatalyst (Nano titanium dioxide) ultramicron is receiving wavelength for 388nm
When following ultraviolet or far infrared, the irradiation of visible ray, similar photosynthetic light-catalyzed reaction can be produced, inside it by
Generation electron hole pair is excited in absorption luminous energy, i.e. photo-generated carrier, its surface is then moved to rapidly and activation is inhaled
Attached oxygen and moisture, produces the oxidability extremely strong free hydroxy of activity and superoxide anion, active oxygen, with very strong
Photoredox function light life group, the energy equivalence of these light life groups in the high temperature of 3600K, with very strong oxidation
Property.Various organic compounds and part inorganic matter in the oxidable pigment for decomposing dental surface and oral cavity, can destroy the thin of bacterium
The protein of after birth and solidification virus, can kill bacterium and decomposing organic pollutant, organic pollution be resolved into free of contamination
Water and carbon dioxide, thus with extremely strong sterilized, degerming functions.Prevent bacterium from being grown on bristle, bristle is kept naturally
Cleaning, disinfection rate is 99.8%.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of implementation method.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need and unable to be exhaustive to all of implementation method.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
