Abstract
The invention discloses a composition and manufacturing technique of reinforced pipe of big diameter reinforced composite polypropylene, which comprises the following parts: 75-100% polyvinyl chloride, 5-15% chlorinated polyethylene, 5-20% polypropylene, 4-6% acrylic ester, 20-40% heavy calcium carbonate, 5-15% ternary ethylen-propylene rubber, 5-6% lead salt stabilizer and 0.5-1.0% stearic acid. The invention can produce new FRPP material through copolymerizing and blending, which overcomes the difficulty of big diameter reinforced pipe and secondary manufacturing.
Description
Technology
This invention relates to the production of materials and reinforced pipe production process, specifically for the production of large
Diameter reinforced pipe production materials and production processes, especially production of large diameter reinforced composite polypropylene
Ene (FRPP) reinforced pipe production materials and production processes.
BACKGROUND
For a long time, domestic enterprises in the production of large diameter drainage pipes, generally are the use of a
Kind of ingredient, suitable with other materials to produce. Produced in this way but through the drain of the
Can not very satisfactory.
Such as polyvinyl chloride pipes, the thermal stability, impact resistance is poor, the heat in the processing
Activity is also poor. The material of the pipe, is difficult to produce large diameter reinforced pipe, production tubing
Average diameter less than DN600mm.
Again polyethylene pipe, and its low coefficient of elastic modulus, compressive strength is poor, secondary plus
Poor work performance, high temperature is poor, and higher raw material prices. The material of the pipe in the south Yi
Deformation, construction inconvenience, easily leak.
Currently the country is still unable to produce large diameter (DN800mm) above FRPP reinforced pipe.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a method for producing large diameter pipe reinforced composite reinforced polypropylene
Composition.
Another object of the present invention is to provide a method for producing large diameter reinforced composites reinforced polypropylene
The composition of tube production process.
In order to solve the above technical problem, the present invention provides the following technical solutions:
For the production of large diameter pipe reinforced glass fiber reinforced polypropylene materials include the following groups
Points and weight:
Polyvinyl chloride 75 to 100
Chlorinated polyethylene 5 to 15
Polypropylene 5-20
4-6 acrylate
Heavy calcium carbonate 20 to 40
Three yuan propylene rubber, 5 ~ 15
5-6 lead salt stabilizer
Stearic acid 0.5 ~ 1.0.
The mesh heavy calcium carbonate is 2500-3000.
Further, further comprising 0.4 to 1.0 parts by weight of an oxidized polyethylene wax.
Further, further comprising 0.4 to 1.2 parts by weight of paraffin.
Further, it also contains 0.5 to 1.5 parts by weight of carbon black.
Reinforced composites for the production of large diameter pipe reinforced polypropylene composition of the production process: Press
Produced the following order:
(a) The weight of each component according to a certain ratio of ingredients;
(b) to step (a) mixing the ingredients in a high thermal blending machine for cold mixing;
(c) to step (b) is expected to join after mixing extruder extrusion granulation;
(d) generated in the previous step of the pellets at 95 twin-screw extruder copolymerized plus
Workers.
The technical effects of the present invention: Using the composition of the present invention is production of large diameter pipe reinforced,
Effective solution to the production of large diameter pipe reinforced molding and secondary processing hard difficulty disadvantages and
Compositions of the present invention production of large diameter pipe reinforced, high temperature performance, especially suitable for
Chemical pipeline sewage (acid and alkali corrosion); elastic modulus coefficient is much higher than HDPE material
Production out of the tube; and high tensile strength.
Specific embodiments
According to specific embodiments of the present invention will be further described:
First, the raw material at a certain weight ratio of the ingredients, parts by weight of the raw materials as follows;
Then have followed weight with a good mix of raw materials in the high-speed mixing machine for hot mix
Cold mix; then mixed with a good mixture by adding extruder extrusion granulation; then the previous step
Pellets produced the 95 twin-screw extruder for further co-processing; final that was used to generate
Production of large diameter pipe reinforced polypropylene reinforced composite composition.
