Description
Technical field
The invention belongs to high-tech functional composite material fields, and in particular to a kind of based on nanometer Cu/C composite materials
The tablecloth of polyester antibacterial plastic concentrate.
Background technology
The tablecloth, be covered in platform, on desktop to antifouling or increase beautiful article.Because being habitually to be covered in table
On son, so also referred to as tablecloth.Due to domestic and international use habit and the specification of desk, shape is different, and title is different, there is fang platform
Set, round platform set, Tea Service set, dinner table set etc., are mainly used for furnishings, dinner party, dining, apply in general to hotel, the elegance such as teahouse
Place.
The tablecloth uses attribute, under moist, nutrition and suitable temperature, makes it easily and cause the growth of microorganism and numerous
It grows.Therefore its antimicrobial treatment is very important.Currently, the antibiotic property of the tablecloth is mainly realized by afterfinish method.By siloxanes
Quaternary ammonium salt, organic halogen class and chitosan class etc. carry out final finishing to cotton fabric, you can assign the antibacterial of the tablecloth to a certain degree
Ability (deer osmanthus universe etc., " synthesis of reactive polymer antibacterial agent and the antibiotic finish to cotton fabric ",《Ion exchange and suction
It is attached》, 2010,26,289-299).
However, these carry out the antibacterial tablecloth of final finishing preparation using homogenous material, durable antibacterial effect is poor, antibacterial
Falling off for agent can also cause environment centainly to pollute.Textile is handled using different antibacterial plastic concentrates, can mutually take long benefit
Short, deficiency when single antibacterial plastic concentrate being avoided to use, the approach is to obtain one of the novel method of excellent antibacterial fabric at present.Example
Such as, carry out water conservancy etc. to arrange (come water conservancy etc., " nanometer Ag/HACC cotton fabric using nanometer Ag/HACC complex antimicrobials
Composite antibacterial arranges ",《Printing and dyeing》, 2010,5-35-37)；Zhao Xiaoyan etc. uses low temperature magnetic sputtering technology, by rare earth/TiO2
Complex antimicrobials handle non-woven cloth, and (Zhao Xiaoyan etc., " magnetron sputtering prepares rare-earth activated TiO2Composite antibacterial is non-to be knitted
Make cloth ",《Textile journal》2008,29,39-43).Though above-mentioned physical method can make the tablecloth obtain good antibiotic property, permanent
Antibacterial ability is explored there is still a need for further.
102499260 A of patent CN disclose a kind of nanometer of Cu/C composite material, to Escherichia coli, golden grape ball
Other fungies such as bacterium, Candida albicans and Bipolaris fungi have antibacterial or bactericidal effect.But due to applying upper technology
Problem, so far there are no the application in macromolecule polymer material.
Invention content
The purpose of the present invention is to provide a kind of tablecloths of the polyester antibacterial plastic concentrate based on nanometer Cu/C composite materials.It is this
The tablecloth for including the polyester antibacterial plastic concentrate of nanometer Cu/C composite materials has lasting, efficient, broad-spectrum antiseptic, nontoxic to human body
It is harmless, will not cause allergy or damage, environmental-friendly, ecological friendly, advantage in human contact.
To achieve the goals above, the present invention uses following technical scheme：
A kind of tablecloth of the polyester antibacterial plastic concentrate based on nanometer Cu/C composite materials, the tablecloth is by blending polyester in proportion
The polyester resin of antibacterial plastic concentrate, after the pre-crystallized of routine, drying, melt-spun prepares antibiotic polyester fiber, then weaves, or and
Cotton, fiber crops and other chemical fibre blended unions form antibiotic fabric；Antibiotic fabric, which arranges to prepare by printing and dyeing, has antibacterial functions
The tablecloth；Wherein polyester antibacterial plastic concentrate is that nanometer Cu/C composite materials, micro-nano inorganic particle, auxiliary agent etc. is blended with polyester resin
It is made by plasticizing, mixing, extrusion, tie rod, cooling, granulation；The raw material of the polyester antibacterial plastic concentrate calculates by weight includes
Following components：36~88 5~20 parts of part, nanometer Cu/C composite materials of polyester resin, 5~25 parts of inorganic particle, coating material
0~5 part of 0.6~3 part, 1~5 part of dispersant, 0.2~2 part of antioxidant, 0.3~4 part of lubricant and stabilizer.
In the technical scheme, nanometer Cu/C composite materials can keep the change of metallic copper for a long time in usual environment
State, under oxidative conditions, nano copper particle can form the equilibrium system of copper-cuprous oxide (1 valence copper), will not generate divalent
Copper.When encountering reducing environment (many bacterial growths will produce reducing environment), the cuprous oxide in copper-cuprous oxide system is again
It can restore as zerovalent copper.Cyclic oxidation-the reduction reaction of such " copper-cuprous oxide-copper " can be related to continuous electricity
Son exchanges, and exactly the exchange reaction of these electronics can generate the growth of microbial cell interference, and then inhibit, destroy cell
Growth, plays the role of antibacterial and sterilization, along with due to cuprous oxide it is not soluble in water, avoid nano copper particle in water
Dissolving, not only prevents pollution of the copper ion to environment, also ensures the durability of copper nano particles.
In the technical scheme, a nanometer Cu/C composite materials can be made to obtain sufficiently effective dispersion；Prevent it because of " group
It is poly- " and the persistence for the antibacterial effect that fails, keeps, enable a nanometer Cu/C composite materials that can have effect in polyester resin
With.This polyester antibacterial plastic concentrate of the present invention can be applied in the antibacterial, antibacterial and anti-corrosion of the tablecloth.
