Description
技术领域technical field
本发明属于塑料建材领域，特别是一种建筑给水用硬质聚氯乙烯(UPVC)管件及其制造方法。The invention belongs to the field of plastic building materials, in particular to a rigid polyvinyl chloride (UPVC) pipe fitting for building water supply and a manufacturing method thereof.
背景技术Background technique
建筑给水管件是包括管道接头等在内的连接件，被广泛地用于在建筑给水行业中。与其它材料生产的给水管件比较，硬质聚氯乙烯(UPVC)管件具有加工容易、粘接方便、价格低、外观质量好、水流阻力小等优点，但是，PVC的分子结构的决定了PVC材料具有较大的脆性，尤其是低温脆性大。因此，在生产建筑给水用硬质聚氯乙烯(UPVC)管件时必须加入抗冲改性剂以提高产品的冲击韧性，抗冲改性剂一般为橡胶或热塑性弹性体，如丁腈橡胶(NBR)、氯化聚乙烯(CPE)等，这类材料的加入虽然能提高硬质聚氯乙烯(UPVC)产品的冲击韧性，但是会引起硬质聚氯乙烯(UPVC)材料的强度下降，导致所生产的管件的耐水压性能下降，给水管件在使用中容易破裂。硬质聚氯乙烯(UPVC)给水管件的耐水压性能和抗冲韧性是本发明要解决的主要问题。Building water supply pipe fittings are connectors including pipe joints, etc., which are widely used in the building water supply industry. Compared with water supply pipe fittings made of other materials, rigid polyvinyl chloride (UPVC) pipe fittings have the advantages of easy processing, convenient bonding, low price, good appearance quality, and small water flow resistance. However, the molecular structure of PVC determines the quality of PVC materials. Has greater brittleness, especially low temperature brittleness. Therefore, when producing rigid polyvinyl chloride (UPVC) pipe fittings for building water supply, an impact modifier must be added to improve the impact toughness of the product. The impact modifier is generally rubber or thermoplastic elastomer, such as nitrile rubber (NBR ), chlorinated polyethylene (CPE), etc. Although the addition of such materials can improve the impact toughness of rigid polyvinyl chloride (UPVC) products, it will cause the strength of rigid polyvinyl chloride (UPVC) materials to decrease, resulting in the The water pressure resistance of the produced pipe fittings is reduced, and the water supply pipe fittings are easily broken during use. The water pressure resistance and impact toughness of rigid polyvinyl chloride (UPVC) water supply pipe fittings are the main problems to be solved by the present invention.
发明内容Contents of the invention

Using this process to produce rigid polyvinyl chloride (UPVC) pipe fittings for building water supply requires higher plasticizing capacity of the injection molding machine.
工艺二，先将PVC树脂、稳定剂、润滑剂、丙烯酸酯树脂按比例加到高速混合机中混合；混合机内物料温度达到90℃～100℃后，然后再将纳米材料加入高速混合机中；在高速混合机内的物料温度升到115～125℃后，将高速混合机内的物料放到冷却混合机内；将物料冷却混合45℃后，将冷却混合机的物料排出；将混合好的物料加入挤出造粒机内，挤出机料筒和机头温度控制在165℃～185℃；将制得的粒料冷却干燥，将干燥后的硬质聚氯乙烯(UPVC)粒料加入注射机内；注射机料筒温度控制在165℃～180℃，熔融塑化的物料注入闭合的模具内，模具内的料温冷却至45℃以下，将模具打开取出制品，即得到本发明涉及的建筑给水用硬质聚氯乙烯(UPVC)管件。根据管件规格的不同，注射过程的工艺条件(包括注射量、注射时间、保压时间、冷却时间、注射压力)需要适当的调整。在用该工艺生产管件时，由于PVC混合料已经被预塑化，因此该工艺对注射成型机的塑化能力的要求比工艺一要相对低一些。Process 2, first add PVC resin, stabilizer, lubricant, and acrylate resin to the high-speed mixer in proportion and mix them; after the temperature of the material in the mixer reaches 90°C to 100°C, then add the nanomaterials into the high-speed mixer ;After the temperature of the material in the high-speed mixer rises to 115-125°C, put the material in the high-speed mixer into the cooling mixer; after cooling and mixing the material at 45°C, discharge the material from the cooling mixer; The material is put into the extruder granulator, and the temperature of the barrel and head of the extruder is controlled at 165°C to 185°C; the prepared pellets are cooled and dried, and the dried rigid polyvinyl chloride (UPVC) pellets are Put it into the injection machine; the temperature of the barrel of the injection machine is controlled at 165 ° C ~ 180 ° C, the molten and plasticized material is injected into the closed mold, the temperature of the material in the mold is cooled to below 45 ° C, the mold is opened to take out the product, and the present invention is obtained.

取聚氯乙烯树脂100kg，铅盐复合稳定剂5kg，丙烯酸酯树脂(ACR401)1.5kg，纳米碳酸钙10kg，将纳米碳酸钙以外的物料投入到高速混合机中，高速混合至物料温度为95℃，再将有纳米碳酸钙加到混合机内，在高速混合机内的物料温度升到115～125℃后将高速混合机内物料排入冷却混合机，将物料冷却至45℃后放料。将混合均匀的物料加入注射成型机内，注射成型机料筒的温度控制在175～185℃，利用注射成型机将塑化好的塑料熔体注入模具内，模具内的塑料冷却至50℃以下后，开模取出制品，即得到本发明涉及的建筑给水用硬质聚氯乙烯(UPVC)管件。Take 100kg of polyvinyl chloride resin, 5kg of lead salt composite stabilizer, 1.5kg of acrylate resin (ACR401), and 10kg of nano-calcium carbonate, and put materials other than nano-calcium carbonate into a high-speed mixer, and mix at a high speed until the material temperature is 95°C , and then add nano-calcium carbonate into the mixer. After the temperature of the material in the high-speed mixer rises to 115-125 ° C, the material in the high-speed mixer is discharged into the cooling mixer, and the material is cooled to 45 ° C before discharging. Put the uniformly mixed material into the injection molding machine. The temperature of the barrel of the injection molding machine is controlled at 175-185°C. Use the injection molding machine to inject the plasticized plastic melt into the mold, and the plastic in the mold is cooled to below 50°C. Finally, the mold is opened to take out the product, and the rigid polyvinyl chloride (UPVC) pipe fitting for building water supply related to the present invention is obtained.
更换模具，可以生产不同形状和规格的建筑给水硬质聚氯乙烯(UPVC)管件，但是，对于不同形状和规格的硬质聚氯乙烯(UPVC)管件，生产工艺(包括注射量、注射时间、保压时间、冷却时间、注射压力)需要一定的调整，这些属于现有技术。根据产品颜色的不同，管件配方中一般需要添加着色剂，如碳黑、酞青蓝、钛白粉等。Changing the mold can produce different shapes and specifications of building water supply rigid polyvinyl chloride (UPVC) pipe fittings. However, for rigid polyvinyl chloride (UPVC) pipe fittings of different shapes and specifications, the production process (including injection volume, injection time, Holding time, cooling time, injection pressure) need certain adjustment, and these belong to prior art. Depending on the color of the product, coloring agents, such as carbon black, phthalocyanine blue, titanium dioxide, etc., generally need to be added to the pipe fitting formula.
