Embodiment Construction

[0013] The present invention is a high-strength pipeline, wherein the high-strength pipeline is composed of polybutene material, wherein additives are added to the polybutene material, and the additive is a toughening agent, or a light stabilizer, or antioxidants, or pigments.

[0014] Further, the toughening agent is a polyolefin material.

[0015] Further, the light stabilizer is a polymeric hindered amine material.

[0016] Further, the antioxidant is a phosphite compound.

[0017] Further, the pigment is a colorant.

[0018] The present invention also provides a method for preparing the above-mentioned high-strength pipeline, the preparation method comprising the following steps:

[0019] First, 6 parts of toughening agent, 5 parts of light stabilizer, 3.5 parts of antioxidant, and 0.5 part of pigment were weighed in parts by weight, and then blended and extruded to obtain master batches, and secondly, master batches and polybutene 1000 parts are dispersed and blended,...

Abstract

A high strength pipeline is formed by polybutylene material, wherein the polybutylene material is added with additive, and the additive is toughening agent, light stabilizer, antioxidant or pigment. The invention also provides a method for preparing the high strength pipeline, which includes the following steps: firstly the toughening agent, the light stabilizer, the antioxidant and the pigment are weighted according to the weight percentage followed by mixing and extrusion granulation to obtain master batch; then the master batch and the polybutylene are distributed and blended followed by extrusion, cooling and cutting to obtain the product. The pipeline of the invention has high heat resistance, good flexibility, and has much better resistance to pressure compared with conventional plastic pipes under the same service temperature.

Description

Technical field: [0001] The invention relates to the construction field, in particular to building components, in particular to pipes, in particular to a high-strength pipe and a preparation method thereof. Background technique: [0002] In the prior art, the plastic cold and hot water supply and heating pipes used in buildings are mainly made of polyolefin materials through extrusion processing, and the main materials are PE (polyethylene, including PE80, PE100, PE-RT, PE -X), PP (polypropylene, including PP-R, PP-B, PP-H), the pipes made of the above materials have a certain pressure resistance within the specified service life, but there are some inherent shortcomings. Such as low strength, poor heat resistance, high brittleness, poor flexibility, etc. Invention content: [0003] The purpose of the present invention is to provide a high-strength pipe, which solves the technical problems of low strength, poor heat resistance, high brittleness and poor flexibility in the...
