Above-mentioned nano material modified PVC water transfer hosetube, its carbon black that uses is high-carbon black pigment, middle colour carbon black or ordinary carbon black pigment.
Preparation method of the present invention: to nanometer CaCO
3Carry out drying and surface treatment, with the nanometer CaCO that handles well
3Mix by a certain percentage with polyvinyl chloride resin, add the back fusion that is mixed of corresponding modified additive, granulation, again after forcing machine is extruded according to certain technological temperature, vacuum sizing cools off, traction, rolling be prepared into nano material modified PVC water transfer hosetube at last.
At present, polyvinyl chloride (PVC) and polyethylene (PE) are the plastic working raw materials that generally uses, because polyvinyl chloride (PVC) RESINS density is bigger, compare with polyethylene and to have higher intensity, rigidity, hardness and lower toughness, elongation at break and shock strength are lower, poor heat stability, the melt viscosity height, processing difficulties, therefore, those skilled in the art thinks and can't produce agricultural delivery hose with PVC all the time, and is that main raw material is produced agricultural delivery hose with polyethylene (PE), and the present invention from the technical point of view, overcome the technology prejudice of this area, with the PVC raw material substitution PE raw material after the modification processing,, make the nano material modified PVC water transfer hosetube after modification is handled have the excellent comprehensive performance by using nano material and multiple modified additive.
