preparation example Construction

[0039] see figure 1 , the preparation method of plastic water pipe material of one embodiment, comprises the steps:

[0040] S110. Add 45-60 parts by weight of mineral oil to 30-60 parts by weight of styrene thermoplastic elastomer and stir for 30-60 minutes to obtain a mixture, and place the mixture at room temperature for 2-4 days.

[0041] The above-mentioned stirring device may be a horizontal mixer, and the mineral oil may be added in a spraying manner, so that the styrene thermoplastic elastomer is more evenly oiled.

[0042] S120, mixing 5-15 parts by weight of polyolefin, 5-15 parts by weight of polyolefin thermoplastic elastomer, 0.1-5 parts by weight of lubricant and 0.1-0.5 parts by weight of antioxidant with the mixture and stirring for 10 minutes to 20 minutes to obtain the premix.

[0043] Specifically, before mixing the above-mentioned raw materials, the above-mentioned raw materials need to be inspected to ensure that all the raw materials used are qualified....

Embodiment 1

[0054] Put 38 parts by weight of Yueyang Petrochemical SEBSYH503T into a horizontal mixer, uniformly add 51 parts by weight of mineral oil Karamay 500SN by spraying, and stir for 40 minutes to obtain a mixture, which is packaged and placed at room temperature for 4 days.

[0055] Put the mixture of 89 parts by weight into a horizontal mixer, add 6 parts by weight of ExxonMobil VistamaxxPOE3980, 5 parts by weight of Thailand Baolin PP1100NK, 0.15 parts by weight of Atmer1753, 0.1 parts by weight of antioxidant 168, 0.1 parts by weight Antioxidant 1076, stirred for 15 minutes to obtain a premix.

[0056] Pour the premixed material into the hopper of the co-rotating twin-screw extruder, shear and disperse through the co-rotating twin-screw, pelletize, pass through a vibrating sieve, blow dry, and cool to obtain the plastic water pipe material.

Embodiment 2

[0058] Put 35 parts by weight of Japanese Kuraray SEEPS4055 into a horizontal mixer, add 53 parts by weight of mineral oil KN4010 evenly by spraying, and stir for 50 minutes to obtain a mixture, which is packaged and placed at room temperature for 4 days.

[0059] Put 88 parts by weight of the mixture into a horizontal mixer, add 7 parts by weight of Borealis FB2230, 5 parts by weight of ExxonMobil PP7373, 0.2 parts by weight of Atmer1753, 0.15 parts by weight of antioxidant 168, 0.15 parts by weight of antioxidant Oxygen 1076, stirred for 14 minutes to obtain a premix.

[0060] Pour the premixed material into the hopper of the co-rotating twin-screw extruder, shear and disperse through the co-rotating twin-screw, pelletize, pass through a vibrating sieve, blow dry, and cool to obtain the plastic water pipe material.

Abstract

The invention relates to a plastic water pipe material. The plastic water pipe material comprises the following components in parts by weight: 30-60 parts of styrene thermoplastic elastomer, 45-60 parts of mineral oil, 5-15 parts of polyolefin, 5-15 parts of polyolefin thermoplastic elastomer, 0.1-5 parts of lubricant, and 0.1-0.5 part of antioxidant. The invention also provides a preparation method for the plastic water pipe material. The styrene thermoplastic elastomer is taken as base material, and is fully mixed with the polyolefin thermoplastic elastomer and other raw materials so as to obtain the plastic water pipe material, the styrene thermoplastic elastomer has good weather fastness, heat resistance and compression deformation resistance, the polyolefin thermoplastic elastomer has narrow relative molecular mass distribution and uniform short branched chain distribution, and the styrene thermoplastic elastomer and polyolefin thermoplastic elastomer are mixed with other materials, so that the product has good plasticity and is stably extruded, the tear strength, tensile strength and elongation at break of the plastic water pipe material are improved, and the plastic water pipe material has excellent elasticity.

Description

technical field [0001] The invention relates to a plastic water pipe material and a preparation method thereof. Background technique [0002] At present, the commonly used plastic water pipe materials are products made by melting and molding synthetic resins and additives. It has the characteristics of light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing and convenient construction. Plastic water pipe materials include thermoplastic pipes and thermosetting plastic pipes. [0003] The main materials used in thermoplastic pipes are polyvinylchloridepolymer (PVC) material, polyethylene (polyethylene, PE) material, thermoplastic polyurethane elastomer rubber (Thermoplasticpolyurethanes, TPU) material, etc. [0004] However, the above-mentioned plastic water pipe materials have poor stretchability and require a larger storage space during use. Contents of the invention [0005] Based on this, it is necessary to provide a plastic water pipe ...
