Description
Technical field
The invention belongs to plastic pipe production technical field, more specifically, relate to PP/PE tubing of a kind of antibacterial, ultraviolet resistance photograph and preparation method thereof.
Background technology
((PE) is two kinds of important resins for universal use for polypropylene (PP) and polyethylene.Polypropylene (PP) over-all properties is better, quality is light, surface luster property is good, mechanical property (as yield strength, tensile strength, surface strength, rigidity and wear resistance etc.) is more excellent, resistance toheat is good, especially be insoluble to common solvent, chemical resistance corrosion, nontoxic, recoverable, non-environmental-pollution under outstanding is its good resisting environmental stress and cracking and room temperature, therefore, more and more applied in chemical building material in recent years.But PP impact resistance is low, low temperature brittleness is given prominence to, and PP very easily photoxidation, make its degradation, work-ing life declines, therefore the impact resistance of research PP is low, and low temperature brittleness, anti-light aging are particularly important.And PE has the features such as excellent electrical insulating property, chemical resistant properties, lower temperature resistance and good processing fluidity, but the shortcomings such as poor heat resistance, easily stress cracking are also quite outstanding.
In conjunction with the advantage of PP and PE, realize the performance complement of PP and PE, adopt the blended of PP and PE to be the important way preparing excellent tubing matrix material.Although PP and PE compound can be improved the shock resistance of PP and the low temperature brittleness of PE by the method for melt blending, but the cause due to both poor compatibility reduces the Rigidity and strength of matrix material, so improve consistency and the bonding strength of PP/PE matrix material, for the PP/PE matrix material obtaining excellent property, there is important practical significance.Meanwhile, when PP pipe applications is in open air, under the irradiation of UV-light, PP is photoxidation very easily, makes its degradation, and work-ing life declines, so improve the UV resistant performance of PP tubing, the outdoor work-ing life of extension tube pipe has great importance.
Current, along with the raising of quality of life, the mankind get more and more to the concern of drinking-water quality, and require also more and more higher, feedwater piping also day by day receives publicity and payes attention to.The life idea of " healthy, safety " also gives environmental protection, high-quality, " green " feedwater piping developing of health and the potential stage of development.At present, because white PP-R water service pipe has light transmission to a certain degree, sun exposure creates the effect of catalytic growth to bacterium, microorganism, makes them accelerate breeding.Thus, the exploitation of " antimicrobial form plastics tubing " and use, to increase water quality and the sanitary condition of pipeline, reduce the attachment of bacterial micro-organism etc., grow, have very large development prospect.At present, existing antiseptic-germicide comprises a few class such as inorganic antiseptic, organic antibacterial agent and natural antibacterial agent, polymer antibacterial agent etc.Although antiseptic-germicide kind number is a lot, only have antiseptic-germicide few in number can meet in antibiotic plastic, what be most widely used at present is utilize the bactericidal property of the metals such as silver, zinc and ion thereof and bacteriostasis property and an obtained class antiseptic-germicide.But this type of antiseptic-germicide and PP tubing are a kind of modes of physical mixed, and its durable antibiotic poor-performing, the metals such as silver, zinc easily move.
