Description
Technical field
The invention belongs to field of materials, relate to a kind of additive, be specially a kind of COPP tubing special assistant SYNOXM4228.
Background technology
China from prohibited in 2000 in newly-built dwelling house, use galvanized pipe as water supply line after, PA tube, polyethylene tube have obtained tremendous development.Can it be divided into HOPP (PP-H), block copolymerization polypropylene (PP-B) and atactic copolymerized polypropene (PP-R) according to different PP polymerization process conditions.Because PP-H tubing fragility has at low temperatures limited its use, is replaced by PP-B tubing, PP-R tubing gradually in some Application Areass.Two kinds of COPPs have different thermomechanical properties and roughly similar normal temperature mechanical property.Wherein the PP-B pipe is mainly used in chilled water system, ground heating system, and the application of PP-R pipe is then more extensive.PP-B, PP-R tubing also have following characteristic except having general plastics tubing characteristics: good sanitation performance, heat-resisting, heat preservation energy-saving; Easy for installation, connect reliable; Raw material is recyclable, and equipment requirements is simple, production technique is easy to be easy to control, and pipeline is laid arbitrarily.Therefore growth momentum was swift and violent in recent years.PP plastic conduit development in recent years is all right, has much the gesture that replaces crosslinked polyethylene pipe, crosslinked polyethylene aluminium composite pipe.
In general, the polypropylene material through chemosynthesis is produced is easy to take place the oxidative degradation phenomenon, the ageing of plastics that just is commonly called as.Tube material is after wearing out, because the molecular structure of material internal changes, the mechanical property of material descends significantly, when bearing internal pressure, is easy to take place explosion.In order to prolong polyacrylic work-ing life as far as possible, need in material, add additive.The kind of additive and add-on and array mode, all processing and the use to material has very big influence.In traditional tube material expressing technique, the additive that needs to add multiple inhibitor and some other subsidiary function reaches the purpose of producing tube material up to specification.But these additives often are difficult in all respects and all reach satisfied effect.Such as, when having guaranteed processing characteristics, because the mass consumption of portions additive in extrusion is affected the work-ing life of material; Perhaps, HUMAN HEALTH is impacted because the material that adds is in use separated out by the current extracting easily; Perhaps, improved and produced unit consumption of energy of tube material or the like owing to after the additive adding, reduced the throughput of extrusion machinery.
So, when producing COPP tubing, needing to add processing characteristics and the mechanical property of some special assistants to improve plastic pipe, creep-resistant properties etc. satisfy the request for utilization of building trade to COPP tubing.
The report that some correlation techniques are arranged at present: Qiu Xiangyu the research of polypropylene pipe processing characteristics (engineering plastics are used, 2002, mention in 30:28) in the random copolymerization polypropylene pipe of its exploitation compacting test qualified.But because the effect of external force, the complicated stress that also produces of crystallisation process, in use pipeline the external force effect such as is hit and is prone to produce fracture.(the modern plastics processed and applied, 2002,14 (3): test respond well in hydraulic test, but it is higher to melt finger, and shock strength is on the low side with the development of PPR special material for tube by the PPR tubing of mentioning its exploitation 5) in feedwater for Yang Aiwu.
