Preferably, in the step (3) four sections charing the specific steps are：
(31)：Just burn section：It is 300 DEG C that retort is set, which just to burn temperature, just burns 30 points with 7-10 DEG C/min of heating rate
Clock；
(32)：First soaking zone：After treating the just burning stage, 30 minutes are kept the temperature；
(33)：High fever section：After treating the first soaking zone, calcining 45 minutes is continued with 7-10 DEG C/min of heating rate；
(34)：Second soaking zone：After treating the high fever stage, 1 hour is kept the temperature.
A kind of manufacturing method of biaxial tension self-reinforcing type PVC pipe, which is characterized in that include the following steps：
(A)：Polyvinyl chloride resin, phenolic resin, nano silicon dioxide and the nitrile rubber of the formula rate is taken to put into height together
In fast blender, 30 minutes postcoolings of 2500rpm high-speed stirreds obtain the first mixture to room temperature；
(B)：Take haloflex, stearic acid, titanium dioxide, precipitated calcium carbonate and the half formula of the formula rate
The tourmaline powder of amount is put into homogenizer together, 30 minutes postcoolings of 1500rpm high-speed stirreds to room temperature, and it is mixed to obtain second
Close material；
(C)：Take the modified fibre of the formula rate, the tourmaline powder of remaining formula ratio, step (A) gained first mixed
Second mixture obtained by closing material and step (B) is put into homogenizer together, and 3500rpm high-speed stirreds stop stirring after forty minutes
It mixes, is cooled to room temperature, obtain mixture；
(D)：Mixture obtained by step (C) is sent into double screw extruder, is extruded under 160-180 DEG C of processing temperature
Type is to get PVC pipe.
The PVC pipe of the present invention can be with various organic and inorganic filler phase as binding agent using phenolic resin
Hold, can increase wetting speed to raw material by adding a certain amount of phenolic resin, phenolic resin and nitrile rubber are simultaneously used as
Sqtructural adhesive, the common glueability for improving polyvinyl chloride resin, the micro-structure of nano silicon dioxide is spherical shape, in cotton-shaped and netted
Quasi- grain structure, according to its distinctive small-size effect and skin effect, nanometer silicon dioxide particle is sufficiently and uniformly disperseed
In the resin material mixed to phenolic resin, nitrile rubber and polyvinyl chloride resin, melted with can preferably carry out crosslinking with resin material
It closes, so as to improve the performance of resin-based materials comprehensively, further improves intensity, elongation percentage, wearability, improve material surface
Finish and anti-aging property, therefore in the PVC pipe preparation method of the present invention, first by polyvinyl chloride resin, phenolic resin, receive
Rice silica and nitrile rubber are stirred together, and with the continuous progress of stirring, temperature can also gradually rise, heat treatment
The mutual mobility between molecule is increased in the process, so that the crosslinking between resin material is more abundant, with to tree
Fat-based materials carry out performance improvement.
The PVC pipe of the present invention improves the micropore of properties of product, modification bamboo charcoal fiber and carbon fiber using modified fibre
More refinement and honeycomb have good adsorption effect, can further improve crosslinked effect；In addition to this, to bamboo charcoal fibre
Dimension is modified first, and the preparation of modification bamboo charcoal fiber uses the mao bamboon in 4-5 growth periods to ensure that bamboo charcoal for raw material
Quality carries out heat pre-treatment to mao bamboon, and to improve the molecular activity of chemical composition in mao bamboon, heating one end time causes molecule
After certain warm-up movement potential energy, mao bamboon is cleaned with ethanol solution, by the principle of similar compatibility, is taken away in mao bamboon
The relatively low oily matter of the molten boiling point that is generated by heating to carry out preliminary cleaning purification to mao bamboon, while carries out mao bamboon
It goes bacterium decontamination, reduces the generation of impurity in the bamboo charcoal fiber generated in subsequent technique, after Grape berry to be added, then pass through four
Section carbonizes to obtain required bamboo charcoal fiber.
Wherein, the processes of four sections of charings are using incremental heating charring process because with temperature difference and
Different variations can occur for the difference of heating time, each chemical constituent in mao bamboon, and the temperature for just burning the stage is controlled to increase, just
Beginning temperature and the first soaking zone, to prevent the imflammable gas that decomposition of components more unstable in mao bamboon goes out to the first burning stage
Influence, if this phase temperature it is excessively high or just burn it is excessively violent, the integrality of the character of bamboo-charcoal particles can be caused certain
It influences, takes high fever section again later, by the raising of temperature, the volatile substance in bamboo charcoal is remained in discharge, improves bamboo charcoal
Fixed carbon content.
Charing operation is carried out to mao bamboon using four sections of charrings in the present invention, it can be so that mao bamboon be preferably able to reaction point
Solution, to obtain the bamboo charcoal fiber of high quality, and the setting of the first soaking zone can smoothly be connected just between burning section and high fever section
Transition, will not because of temperature sharp increase so that in mao bamboon chemical constituent carry out violent decompose suddenly and moment generate it is a large amount of
Fuel gas or other exhaust gas, while it is also possible that in mao bamboon chemical constituent under a relatively stable temperature range into
The lasting reaction of row, with ensure the first stage just to burn the stage the reaction was complete fully, sundries discharge it is more thorough, pollutant
Less generation, then carries out the processing of high fever section again, the setting of the second soaking zone be in order to make full use of high fever section after
Residual temperature, reduces the generation of pollutant, and enables the molecule of chemical constituent after high fever section relatively mild at one
It is slowly settled out under temperature range, bamboo charcoal fiber tool is caused while charing completely, and there are one the ductility and diffusion stablized
Property, the bamboo charcoal fiber molecular activity bigger obtained after such four sections of charing process, adsorption area bigger, adsorption capacity is more
By force.
Since bamboo charcoal fiber is per se with certain negative electrical charge, double dodecyl hydroxypropyl quaternary ammonium salts can adsorb well
In bamboo charcoal fiber surface, the electrostatic of bamboo charcoal fiber and interfibrous friction are effectively reduced, makes fiber stretch without being easily bonded to
Group, so as to obtain certain soft effect, the present invention presses the bamboo charcoal fiber after charing and double dodecyl hydroxypropyl quaternary ammonium salts
According to weight percent 1：1 mixed proportion, which be modified again, has obtained the modified bamboo finally with good flexibility and extensibility
Carbon fibe in the preparation method of subsequent PVC, is preferably adhered to or is crosslinked with other components, further to reduce most
Shrinking percentage, enhancing dimensional stability, hardness and the elevated temperature strength of whole pipe material product.
The tourmaline powder of the present invention can gradually gather certain charge on its surface, pass through electricity by constantly stirring
It attracting each other between lotus and rubs, further improves the activity between molecule, to increase crosslinked effect, the present invention will be electrical
Stone powder has carried out segmentation addition with adequately so that the component in each stage can be more preferable in the manufacturing method of PVC pipe
Crosslinking.
