Description
Technical field
The present invention relates to tubing preparations more particularly to a kind of AGR pipe and preparation method thereof.
Background technique
AGR (Ackylic Graft Resin) is the acrylic (Acrylieester, acrylic resin) by ultramicron
Elastomer sufficiently cooperates among polyvinyl chloride molecule, with novel resin material made of chemical copolymerization combination, Chinese name
Title is acrylic acid copolymer polyvinyl chloride.This material has excellent shock resistance and resistance to low temperature (≤- 10 DEG C), safety
Hygienic, reliable and stable, long service life, quality comply fully with the requirement of the drinking purified pipe standard of health ministry, are
Town and country high standard water supply network, national one of infrastructure engineering and permanent work first choice water-feeding pipes.
AGR pipe-line system can not have to concern pipeline in transport, construction at all in subzero 30 DEG C of extremely frigid zones normal use
It can occur to impact breakage event in the process.AGR pipe-line system shock resistance is brilliant.Under the conditions of -10 DEG C, the pipe of Dn20
Material can bear 1Kg weight, the freely falling body of 2m height is impacted without cracking；The tubing of nominal diameter 75cm or more can be with
The freely falling body impact of 10Kg weight, 2.0m height is born without cracking, and other plastic pipes fittings are in same item
It when comparing experiment under part, can all be pounded to crush by weight, the impact test of this high intensity can not be withstood.
AGR pipe-line system tensile strength is 50.3~53.2MPa, elasticity modulus 2156MPa, linear expansion coefficient are only 6
×10-5M/m DEG C, these rigorous, science testing results show it with good rigidity.Compared with the pipelines such as PP-R, PE,
AGR pipeline is unlikely to deform heat, no matter it is bright dress or concealed installation be suitable for；The supporter needed in the construction process is few, it is beautiful and
Construction cost is low.Rigid height also ensures that AGR pipe part can bear biggish pressure resistance, and under the conditions of equipressure, the wall thickness of AGR is wanted
Wall thickness than pipelines such as PP-R, PE is thin, just can reach identical water flow using the AGR pipeline compared with small diameter tube, so as to save
Province's expense and raising installation effectiveness.
AGR pipe-line system uses the dedicated No.80 adhesive of ponding.This adhesive and AGR resin compatibility are very good, Gu
It is fast to change speed, to realize the double effects of excellent adhesive strength and rapid construction.By the connector of tubing and pipe fitting into
The detection of row burst pressure tests generates the position for bursting and destroying all on tubing, and the connecting portion of tubing and pipe fitting is never
It can occur to leak or destroy；It is sampled from the connecting portion of tubing and pipe fitting and carries out tension test, the position of rupture failure is also whole
On tubing, and tubing is Nian Jie with the connecting portion of pipe fitting intact.Under the conditions of 17.5Kg hydrostatic pressing, by the company of tubing and pipe fitting
Socket part position carries out ± 4 degree of hydrostatic pressing cripping test repeatedly, and bending 2000 times or more joint area will not leak or loosen.
These harsh tests all demonstrate AGR tubing and the adhesive strength of pipe fitting is high, can construct stronger, more secure and reliable water supply
Pipe network.AGR pipeline is not influenced by chlorine residue in water, many polyolefine materials, such as when PP, PE, PB encounter the chlorine residue in water, can
Polymer segment decomposition, which can occur, leads to pipeline metrorrhagia and metrostaxis, it was reported that the U.S. was just it has been found that such problem occurred for PB pipeline.
AGR is not influenced by chlorine residue in water, this more enhances the security reliability of AGR pipe-line system.
Summary of the invention
The present invention provides a kind of AGR pipe and preparation method thereof.
The technical scheme to solve the above technical problems is that a kind of AGR pipe, which is characterized in that in parts by weight
Meter, including following component: 80-120 parts of GKC, 3-5 parts of MBS, 1-4 parts of heat stabilizer, 1-2 parts of lubricant, defoaming agent 0.2-
0.8 part, 0.3-0.6 parts of pigment, 0.3-0.7 parts of calcium stearate, 0.6-1 parts of stearic acid.
Wherein, the heat stabilizer is one of thiol methyl tin, lauric acid antimony or sad antimony；The lubricant is PE
One of wax, paraffin or OPE wax are a variety of；The defoaming agent is octadecyl alcolol or hexadecanol；The pigment be carbon black, ultramarine and
Mixture of the titanium dioxide by weight 1:1:1.
The invention also discloses the preparation methods of above-mentioned AGR pipe, comprising the following steps:
1) each component is weighed by weight, is uniformly mixed in blending bucket；
2) twin-screw extrusion electromechanical source is opened, extruder temperature is set and mold temperature is 175 DEG C, preheats 4h；
3) blending bucket is opened, setting screw speed is 15-16rpm, and fusant is squeezed out through mold；
4) tubing of extrusion is successively imported into vacuum cooled cylinder and spraying box, last drawing and forming.
The beneficial effects of the present invention are: AGR pipe of the present invention is low temperature resistant, intensity is high, strong shock resistance, pipeline cleanliness
Height, corrosion resistance and good can be applied to the conveying of fine chemistry industry and electronics industry cleaning water conveying system, life direct drinking.This
It is simple to invent AGR tube preparation method, large-scale continuous production can be met.
