Problems solved by technology

[0004] In the prior art, pipe fittings are formed by multi-layer compounding. However, due to the large difference in the connection strength between the materials in each layer, it is easy to cause the problem that the high-pressure resistance is not good enough

Embodiment 1

[0057] Example 1: A high-pressure resistant pipe, the components included and the corresponding parts by weight are shown in Table 1, and are prepared by the following steps:

[0058] S1, mixing PVC resin, heat stabilizer, filler, impact aid, lubricant, light stabilizer, and coloring agent uniformly to obtain a first mixture;

[0059] S2, granulating the first mixture obtained in step S1 to obtain materials for high-pressure pipe fittings;

[0060] S3, extruding the high-pressure resistant pipe material obtained in step S2 to obtain the high-pressure resistant pipe.

[0061] Among them, the heat stabilizer is a calcium-zinc heat stabilizer;

[0062] The filler is nano calcium carbonate;

[0063] The impact resistance agent is KANEACE B-561 impact modifier and KANEACE PA101 processing aid with a weight ratio of 4:1;

[0064] Lubricants are ethylene bis-stearamide, oxidized polyethylene wax, and paraffin with a weight ratio of 1:1:1;

[0065] The light stabilizer is the ultraviolet absorber ...

Embodiment 2-5

[0067] Embodiment 2-5: A high-pressure resistant pipe fitting, which is different from Embodiment 1 in that the included components and their corresponding weight parts are shown in Table 1.

[0068] Table 1 The components included in Examples 1-5 and their corresponding parts by weight

[0069]

Embodiment 6

[0070] Example 6: A high-pressure resistant pipe fitting. The difference from implementation 1 is that all the impact additives are KANE ACE B-561 impact modifiers.

Abstract

The invention discloses a high-pressure-resisting pipe fitting and its preparation technique. The high-pressure-resisting pipe fitting is prepared from, by weight, 100 parts of PVC resin, 5-9 parts ofheat stabilizer, 10-15 parts of filling agent, 6-11 parts of antishock assistant, 0.25-0.9 part of lubricant, 0.1-0.5 part of light stabilizing assistant, and 0.2-0.9 part of coloring agent; the antishock assistant includes at least one of KANE ACE B-561 anti-impact modifier, KANE ACE PA 101 processing assistant; the lubricant includes at least one of ethylene bis-stearamide, oxidized polyethlenewax and paraffin. The high-pressure-resisting pipe fitting has a smooth surface and is not easy to scale; besides, the high-pressure-resisting pipe fitting can reduce fluid resistance and has good high-pressure resisting effect.

Description

Technical field [0001] The invention relates to the technical field of plastic materials, more specifically, it relates to a high-pressure resistant pipe fitting and a preparation process thereof. Background technique [0002] High-pressure pipe fittings refer to pipe fittings with higher pressure resistance. In my country's chemical standards, high-pressure pipe fittings can withstand pressure ≥16MPa. High-pressure pipe fittings are used in specific environments, such as high-pressure steam equipment, chemical high-temperature and high-pressure pipelines, etc. [0003] The Chinese patent with publication number CN1436649A and publication date on August 20, 2003 discloses a method for preparing a multilayer plastic composite pipe. The inner layer to the outer layer is reinforced by a corrosion-resistant and anti-friction layer, an adhesive layer, and glass fiber. The four-layer composite material is composed of four-layer composite material and the anti-corrosion and impact-resist...
