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 as well as a preparation method and application thereof. The performance of the PVC-U drainage pipe fitting is improved by using an environment-friendly lead-free heat stabilizer, superfine nano active calcium carbonate and a composite efficient environment-friendly nano inorganic antibacterial mildew-proof modifier, the pipe fitting is not easy to migrate, separate out and discolor, the appearance smoothness and brightness of the pipe fitting are obviously improved, the flow resistance is small, and the pipe fitting has good physical and mechanical properties of wear resistance and impact resistance; the pipe fitting has the advantages of excellent hydrophobic performance, smooth and flat surface, low interface free energy and difficult adhesion of a carrier and silt, so that the pipe fitting has the advantages of extremely strong dirt resistance, small flow resistance, difficult scaling and discoloration, and longer service life; and the antibacterial and mildew-proof effects are lasting, safe and efficient, a pipeline system is not easy to block, and the pollution of mildew to water quality 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...
