Embodiment 1

[0032] Weighing each composition includes the following parts by weight:

[0033] 60 parts of PVC, 10 parts of MBS, 5 parts of CPE, 5 parts of PP, 3 parts of rare earth stabilizer, 1 part of polyethylene wax, 2 parts of isopropyl triisostearyl titanate, 1 part of carbon fiber, and 1 part of titanium dioxide.

[0034]First heat and stir the PVC for 2 minutes; add stabilizer and continue stirring; raise the temperature to make the mixture temperature reach 95°C, add other additives (the carbon fiber and titanium dioxide are pre-surface treated with isopropyl triisostearyl titanate) and mix Stirring; stop stirring when the mixing temperature reaches 120°C; send the mixed material to the cooling agitator for stirring and cooling to 40°C and discharge, then send it to the next process for processing for 4 hours.

Embodiment 2

[0036] Weighing each composition includes the following parts by weight:

[0037] 70 parts of PVC, 20 parts of ACR, 10 parts of NBR, 10 parts of PP, 4 parts of rare earth stabilizer, 2 parts of ethylene bis stearic acid amide, 3 parts of monoalkoxy titanate, 3 parts of carbon fiber, 8 parts of titanium dioxide .

[0038] First heat and stir the PVC for 2 minutes; add stabilizer and continue to stir; raise the temperature so that the temperature of the mixture reaches 98°C, add other additives (the carbon fiber and titanium dioxide are pre-surface-treated with monoalkoxy titanate) and mix; mix Stop stirring when the temperature reaches 125°C; send the mixed material to a cooling agitator for stirring and cooling to 42°C, and then send it to the next process for processing for 5 hours.

Embodiment 3

[0040] Weighing each composition includes the following parts by weight:

[0041] 80 parts of PVC, 30 parts of PMI-g-ABS, 10 parts of PP, 10 parts of NBR, 10 parts of CPE, 6 parts of rare earth stabilizer, 3 parts of ethylene dioleic acid amide, 5 parts of isopropyl triisostearyl titanate Ester, 5 parts of carbon fiber, 15 parts of nano-scale light calcium carbonate.

[0042] First heat and stir the PVC for 2 minutes; add a stabilizer and continue to stir; raise the temperature so that the temperature of the mixture reaches 95-100°C, and add other additives (including carbon fiber and nano-scale light calcium carbonate with isopropyl triisostearyl titanate ester pre-surface treatment) mixing and stirring; stop stirring when the mixing temperature reaches 130°C; send the mixed material to the cooling agitator to stir and cool to 45°C, and then send it to the next process for processing for 6 hours.

Abstract

The invention discloses an anti-impact modified polyvinyl chloride water and sewage drainage pipe. The anti-impact modified polyvinyl chloride water and sewage drainage pipe comprises, by weight, 60-80 parts of PVC, 10-30 parts of anti-impact modifiers, 10-30 parts of toughening modifiers, 3-6 parts of modifiers, 1-3 parts of lubricants, 2-5 parts of coupling agents, 1-5 parts of carbon fibers and0-15 parts of fillers. A processing method includes heating and stirring the PVC for 2 minutes, adding stabilizers, continuing to stir, increasing the mixing temperature to 95-100 DEG C, adding otherauxiliaries (the carbon fibers and the fillers are subjected to surface treatment by the coupling agents), performing mixing and stirring, stopping stirring when the mixing temperature reaches 120-130 DEG C, feeding the mixtures to a cooling stirrer to be stirred and cooled to 40-45 DEG C, discharging the mixtures, and feeding the mixtures to a next step for 4-6 hours of processing. The obtainedpipe has high impact strength, temperature resistance, corrosion resistance and aging resistance.

Description

technical field [0001] The invention belongs to the field of drainage and sewage pipes, in particular to an impact-resistant modified polyvinyl chloride drainage and sewage pipe. Background technique [0002] Polyvinyl chloride (PVC) pipes use polyvinyl chloride resin as the main raw material. Polyvinyl chloride pipes are widely used for their light weight, excellent mechanical strength, excellent chemical resistance, corrosion resistance, chemical resistance, heat insulation, electrical insulation, etc., long life, and low price. use. [0003] However, when the above-mentioned polyvinyl chloride pipes are used as civil engineering and construction materials, there are disadvantages such as poor impact strength, insufficient toughness, and easy aging. On the one hand, due to its poor impact resistance and toughness, it is prone to brittle damage during transportation, installation and use; Therefore, improving various properties such as impact resistance, toughness and ag...
