Embodiment 1～2 and comparative example 1

[0068] A PVC-U drainage pipe fitting, including the components calculated in parts by weight as shown in Table 1 below.

[0069] The components and parts by weight of the PVC-U drainage pipe fittings of each embodiment and comparative example in table 1

[0070]

[0071]

[0072] The preparation method of above-mentioned PVC-U drainage pipe fitting, comprises the steps:

[0073] S1. After mixing according to the ingredients of each raw material, add it to a high-speed hot mixer for high-temperature and high-speed kneading and dispersion. When the temperature reaches 115°C, transfer to a cold mixer to stir and cool at a low speed. When the temperature drops below 55°C, discharge it into Hopper, ready for use;

[0074] S2. Add the ready-to-use mixed ingredients in the hopper described in S1 to a twin-screw extruder for plasticization, extrude and granulate, pelletize, cool in a vibrating tower, and pack the pellets; the twin-screw extruder is anisotropic parallel For the...

Abstract

The invention discloses a PVC-U drainage pipe fitting and its preparation method and application. The use of an environmentally friendly lead-free heat stabilizer, ultrafine nano-active calcium carbonate, and a composite high-efficiency environmental-friendly nano inorganic antibacterial and anti-mildew modifier component improves PVC-U. The performance of U drainage pipe fittings, the pipe fittings are not easy to migrate, precipitate, and change color, and the smoothness and brightness of the appearance of the pipe fittings have been significantly improved, the flow resistance is small, and they have good physical and mechanical properties of wear resistance and impact resistance; the pipe fittings have excellent Hydrophobic performance, smooth and flat surface, low interface free energy, difficult to adhere to the carrier and sediment, so that the pipe fittings have strong anti-fouling ability, small flow resistance, not easy to scale, discoloration, longer service life; antibacterial and anti-mildew effect Durable, safe and efficient, the pipeline system is not easy to block, and the pollution of water quality by mold is avoided.

Description

technical field [0001] The invention relates to the technical field of drainage pipe fittings, in particular to a PVC-U drainage pipe fitting and its preparation method and application. Background technique [0002] PVC-U drainage pipe fittings have good mechanical properties, corrosion resistance, electrical insulation, low cost, light weight, and easy processing, so they are widely used in construction, household, agriculture, and municipal engineering, especially in civil building materials and municipal engineering In the field of drainage and sewage, because most of the open-air water quality that this type of drainage and sewage system contacts is rich in organic matter and minerals, it is easy to breed mold and algae in the water, especially in key parts such as pipe joints. Due to the growth of mold and algae The growth causes the decline of the physical properties of the pipe fittings, the blockage of the pipe fittings, the pollution of mold and algae, and the short...
