Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new slow-release environmentally friendly stabilizer applied to PVC double-layer shaft hollow pipes, which solves the problem that the existing calcium-zinc stabilizer is applied to the raw materials of PVC double-layer shaft hollow pipes. During the production process, the performance of the PVC double-layer shaft hollow pipe after production is single, and at the same time, the degradation speed is fast and the thermal stability is poor, which affects the stability of the subsequent pipe in practice.

Embodiment

[0037] A new slow-release environmentally friendly stabilizer applied to PVC double-layer shaft hollow tubes, using raw materials containing the following weight percentages:

[0038] Zinc stearate 20%;

[0039] Calcium stearate 5%;

[0040] Syke 10%;

[0041] Uracil 2%;

[0042] Zeolite 36%;

[0043] Calcium hydroxide 8%;

[0044] Antioxidant 3%;

[0045] Synergistic heat stabilizer 10%;

[0046] Polyol 6%.

[0047] Prepared by following steps:

[0048] Step 1. Stir zinc stearate, calcium stearate, Cyclo, uracil and polyhydric alcohol in proportion at 28°C for 10 minutes;

[0049] Step 2, add zeolite and calcium hydroxide and mix and stir for 17 minutes;

[0050]Step 3. Finally, add synergistic stabilizers, antioxidants and high-performance graphene oxide calcium-zinc stabilizers and stir for 6 minutes at 75°C with nitrogen protection, and obtain PVC stabilizers after cooling;

[0051] Step 4, for the PVC stabilizer that obtains in the step 3, adopting outer diamete...

Abstract

The invention discloses a novel slow-release environment-friendly stabilizer applied to a PVC double-layer shaft hollow tube. The stabilizer comprises the following components in percentage by weight:20% of zinc stearate, 5% of calcium stearate, 10% of Sika, 2% of uracil, 36% of zeolite, 8% of calcium hydroxide, 3% of an antioxidant, 10% of a synergistic heat stabilizer and 6% of polyol. The invention relates to the technical field of hollow tube stabilizers. According to the novel slow-release environment-friendly stabilizer applied to the PVC double-layer shaft hollow pipe, the problems that when an existing calcium-zinc stabilizer is applied to the production process of raw materials of the PVC double-layer shaft hollow pipe, the produced PVC double-layer shaft hollow pipe is single inperformance, high in degradation speed and poor in thermal stability, and the actual stability of subsequent pipelines is affected are solved.

Description

technical field [0001] The invention relates to the technical field of hollow tube stabilizers, in particular to a new slow-release environmentally friendly stabilizer applied to PVC double-layer shaft hollow tubes. Background technique [0002] There are more and more municipal rain and sewage separation, drainage pipeline reconstruction projects, and sponge city construction, and the demand for drainage pipes and inspection wells is increasing. Compared with cement pipes and inspection wells, hard polyvinyl chloride (PVC-U) double-layer axial hollow wall pipes and polyvinyl chloride (pvc) inspection wells have good connection sealing performance, corrosion resistance, convenient transportation, fast construction, and save construction time obvious advantage. It is used more and more in drainage projects in our country. [0003] Existing calcium-zinc stabilizers are used in the production process of PVC double-layer shaft hollow pipe raw materials. After production, the P...
