Description
Technical field
The present invention relates to tubing technical field, particularly relate to a kind of antimicrobial polyvinyl chloride plastic pipe and preparation method thereof.
Background technology
CNT has the strongest axial strength, toughness and elastic modelling quantity, draws through Theoretical Calculation: the Young's modulus of CNT can reach 5TPa, higher an order of magnitude than general fibre;Its Theoretical Tensile Strength is 50-20OGPa, for steel 100 times, but density only has 1/6th of steel, in addition, the cage structure of CNT hollow can occur certain volume deformation when by external force strong effect, and then show as out good pliability, it can be regarded as the most excellent fiber " and the tensile strain that CNT is born, brittle fracture will not be presented, plastic deformation fracture or bond fission, therefore, the structure of CNT than common high molecular materials firm much, at present, the compound composite prepared is carried out with other engineering material with CNT as filler, show surprising intensity, elastic, toughness and fatigue resistance etc., this just provides the widely scope of application for CNT；
The specific surface area huge due to CNT and surface can, CNT is made to be very easy to reunite, this can limit its dispersion in various matrixes virtually, effectively improve CNT dispersion in the base, it is made can more efficiently to transmit load, having become as CNT and apply institute's urgent problem, therefore, the surface modification of CNT is particularly important；
nullAnd owing to CNT can improve the mechanical property of composite、Electrical property and other performances，So CNT/rubber composite causes increasing concern，In order to realize the purpose strengthened，Two problems are had to need to solve: one is the scattering problem of CNT、Another is the interface problem of CNT and matrix，Owing to carbon nano tube surface compares relatively inert，And specific surface area easily causes more greatly reunion，So the effect of carbon nanotubes reinforced polymer is not clearly，Based on this reason，A lot of people start CNT is carried out physical or chemical treatment，In the middle of these methods，It is a kind of conventional and efficient that acid treatment produces the method for oxy radical，Because it can be provided with the reflecting point of effect，Thus realize chemical bond with matrix resin and be connected，But，In most cases,The group that this method produces is the most little，The connection that can not provide enough is bonded with matrix；
CNT has the performance of every excellence due to it, the most extremely concern of various countries' research worker, especially carbon nanotube composite materials is owing to it can possess function that more original CNT do not possesses or strengthens CNT and possesses but more weak function, the present invention is just to provide a kind of functionalization and strengthens CNT, and its composite is applied in life production field on conventional tubing, the effect reaching to improve pipe performance with this.
