Alternate copolymer shows signs of anger carrier, addition diffusing oil and silane coupling agent to surface of pigments wetting, and obtained tubing inside and outside wall is smooth
Smooth, product meets the related request in national standard, compared with the tubing of regular convention formula production, the mechanical property of pipe fitting and resistance to
Ageing properties etc. are significantly improved, and the extension of tubing oxidation induction time, the raising of tubing impact strength, tubing hydraulic pressure are strong
Degree and tubing ageing-resistant performance increase.
Another embodiment provided by the invention, a kind of manufacturing method for manufacturing aforementioned PPR three-way pipes, which is characterized in that packet
Include following steps：
Step A, injection molding PPR three-way pipes embryo material 1, the PPR three-way pipes embryo material include the first connecting pin, the second connection
End, third connecting pin have straight pipe between the third connecting pin and the first connecting pin, the second connection end；Step B, heating
The PPR three-way pipe embryo materials；Step C, perpendicular to first connecting pin, second connection end, third connecting pin axis where it is flat
Face is bent the straight pipe and forms the space for accommodating PPR pipe.
The manufacturing method of above-mentioned PPR three-way pipes, step B include heating the PPR three-way pipes embryo material to 130 DEG C -140 DEG C.It needs
It is noted that the softening point of PPR pipe part is 131.5 degree.
As being further improved for said program, by preferred, 135 DEG C are optimum temperature.
With reference to figure 4 and Fig. 5, further, the manufacturing method of above-mentioned PPR three-way pipes, the step B will be included after heating
PPR three-way pipes embryo material 1 is put into lower die 42, and driving upper mold 41, which pushes, is bent the straight pipe, after PPR three-way pipes cooling
The upper mold is driven to rise, it is corresponding that the upper mold and the lower die offer first connecting pin, second connection end, third connecting pin respectively
The semicircular locating slot 43 in section；The upper mold includes downward raised press section 51, and the lower die has and the extruding
The corresponding notch 52 in portion, the press section are equipped with the semicircular contact groove 53 being bonded with the straight pipe outer surface.This field skill
Art personnel should be understood that the positioning of locating slot and contact groove completion to tee pipe fitting embryo material to be processed, protrusion is squeezed
Splenium can be adjusted according to the space 3 for accommodating PPR pipe.Above-mentioned mold may be arranged as diversified forms, to meet processing
The needs of various forms of PPR bridge types three-way pipes.
Further, the manufacturing method of above-mentioned PPR three-way pipes, which is characterized in that the driving upper mold pushes bending institute
It states to be additionally included in the straight tube end before straight pipe and fills in flexible rod, the flexible rod is for preventing the straight pipe should when being bent
The section deformation of straight pipe is excessive.
Specifically, during above-mentioned manufacturing method, multiple and different PPR fusion temperatures are set：Preceding barrel：200-240
Degree, middle barrel 160-190 degree, rear barrel 160-190 degree removes deviation as possible in actual production, can reduce well overlap and
Contraction problem.Mold temperature uses 50 degree or so, and molding effect is best, too low (being less than 40 degree) the tube surface gloss difference of temperature,
Too high (being more than 90 degree) the pipe fitting buckling deformation of temperature, systolic depression.
For above-mentioned processing and manufacturing scheme specifically, since PPR molding shrinkages are big, size is unstable, yielding receipts
Therefore the characteristics of contracting, can drop molding shrinkage by improving injection pressure and injection moulding speed to reduce shearing strength between layers
It is low, but PPR mobility is fine, easily occur when injection pressure is big overlap and it is directional strong the defects of, injection pressure is generally：
50-70MPA.Here it is preferably one section of 60MPA, two sections of 60MPA, three sections of 45MPA.Injection moulding speed is preferably one section 55, two section 50,
Three section 45.In addition, dwell pressure takes percent 80 of injection pressure or so, longer dwell time feeding and longer cold is preferably taken
But the time ensures plastics size, deformation extent.About molding cycle, since product wall thickness is thicker, by the pipe of injection molding completion
Part is put into baking oven, and the softening point of PPR pipe part is 131.5 degree, so the temperature range of baking oven setting is 130-135 degree, 135
It spends for optimum temperature, standing time is 1 hour or so.The pipe fitting of its baking oven is taken out, is placed in molding die, passes through hydraulic pressure
Machine compression moulding.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
