Description
Technical field
The present invention relates to a kind of self-cleaning materials in the tube and preparation method thereof and its multiple tube being made, belong to tubing technical field.
Background technology
The advantages of PPR pipe is because of its good wholesomeness, toughness, resistance to pressure, in China, building field is widely used.
Nontoxic salubrity is required PPR plastic tubes in itself, but the characteristic due to PPR raw materials in itself makes its pipeline being made not have self-cleaning work(
Can, under this specific environment of household water, the technique and the outmoded of pipe network that the pollution at water source, waterworks fall behind do not conform to
Reason, in use for some time, inside pipe wall secondary pollution is serious for PPR plastic tubes, is that bacterium, Legionella, microorganism and algae are planted
The breeding place of thing, seriously threatens health, and this defect is necessary to be improved.
Kynoar (PVDF) has splendid chemical resistance and anti-permeability, containing extremely low extractable matter or completely
Without extractable matter.For extractable matter, PVDF is one of most pure commercially available polymer, is also to have to whole chemical substances
There is the semi-crystalline polymer of splendid chemical resistance.In addition, PVDF is for water, carbon dioxide, oxygen and HC fuel and many
Other compounds have splendid anti-permeability.
The existing pure PVDF pipes of in the market can independently be used in civilian house ornamentation aqueduct, can effectively prevent in-tube fouling from pressing down
Bacterium processed and algae infestation attachment, but its high price is difficult to be received by normal domestic customer.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of self-cleaning materials in the tube and preparation method thereof and its it is made
Multiple tube.
To achieve these goals, the present invention is to realize by the following technical solutions：
A kind of self-cleaning materials in the tube, include the raw material of following parts by weight：50-60 parts of Kynoar, poly-methyl methacrylate
35-46 parts of ester, maleic anhydride modified polypropylene 2-8 parts and 0.1-0.5 parts of tristerin.
A kind of described self-cleaning materials in the tube, include the raw material of following parts by weight：55 parts of Kynoar, polymethylacrylic acid
0.3 part of 40.7 parts of methyl esters, 4 parts of maleic anhydride modified polypropylene and tristerin.
A kind of described self-cleaning materials in the tube, include the raw material of following parts by weight：50 parts of Kynoar, polymethylacrylic acid
0.1 part of 35 parts of methyl esters, 8 parts of maleic anhydride modified polypropylene and tristerin.
A kind of preparation method of described self-cleaning materials in the tube, each raw material mixes 4h according to parts by weight under the conditions of 75 DEG C, then
Mixed using high speed batch mixing mixer, finally carry out blending granulation using the parallel double-screws of φ 50 blending granulation unit.
A kind of self-cleaning multiple tubes of three-layer co-extruded PPR, including internal layer, middle level and outer layer, the internal layer by it is described it is a kind of from
Clean materials in the tube are made, and the middle level is transition zone, and the outer layer is made up of PPR materials.
A kind of described three-layer co-extruded self-cleaning multiple tubes of PPR, the usage amount of the self-cleaning materials in the tube accounts for total multiple tube unit weight
The 10% of amount.
Beneficial effects of the present invention：The self-cleaning materials in the tube moisture content of the present invention<0.3, outward appearance to be transparent or semitransparent, its with it is outer
Layer PPR coextrusion composite molding surface smoothness (or roughness Ra≤0.1 μm) level is not less than the shaping table of conventional PPR materials
Face.The molding shrinkage (containing the expansion and contraction for depositing and using process) and the PPR or intermediate function of coextrusion of self-cleaning materials in the tube
Layer material is basically identical.The tubing produced with self-cleaning materials in the tube meets standard GB/T/T18742.2-2002 standards.
The self-cleaning multiple tubes of three-layer co-extruded PPR of the present invention solve PVDF can not with the compound inside and outside layer of PPR resin coextrusion
Laminating, and the unstable problem of delamination separation equidimension.
The self-cleaning multiple tube：Inner wall roughness：0.1 μm of Ra ＜
Boiling water digestion：50mm length pipeline section 10 is intercepted, 95 DEG C of water loggings are boiled 1 hour.Normal temperature is naturally cooled to, is not found interior
Layer deformation and peelable situation.
Long-term storage：Standard sample pipe (6m) is deposited one week to six months, and differentiation contraction does not occur causes deformation with peeling off
Delamination.
The physical property of tubing meets GB/T18742.2-2002 standards.
