Embodiment 3

[0052]according tofigure 1 The workflow is 100 parts of the hydrogenated styrene-butadiene block copolymer (SEBS), 75 parts of polypropylene (PP), 10101.6 parts of an antioxidant, 1680.8 parts of an antioxidant, 7.5 parts of antisjone and nanocarbon acid. Calcium 7.5 comparisal weighing each raw material is added to the high mixing machine at high speed for 20 minutes, disconnected; then mix the mixed material to extrud the granulation in the twin screw extruder, the extrusion temperature is 200 ° C, machine The head temperature was 190 ° C; the extrudate was injection molded into the mold at 220 ° C, and the temperature was maintained at a vacuum condition for 8 hours, and the cooling cure obtained the water tube C.

[0053]The resulting hose C is tested in heavy metal water in accordance with the test method of the BS6920-2000 standard, and the results are shown in Table 7. From the table, it can be seen that the weight of the heavy metal dissolution of the obtained hose C is not exc...

Abstract

The invention discloses an environment-friendly water supply hose without increasing the total organic carbon content in the water body, which is characterized in that it is made of hydrogenated styrene-butadiene block copolymer (SEBS), polypropylene (PP), heat stabilizer , dispersant, filler, the mass ratio of each component is: SEBS: 100 parts; PP: 10-75 parts; heat stabilizer: 0.5-2.5 parts; dispersant: 0.3-7.5 parts; filler: 0.5- 75 servings. The invention also provides a preparation method of the water supply hose. The water supply hose prepared by the invention can effectively inhibit the organic matter in the pipe body from migrating into the water body, meets the requirements of safety standards, and has good environmental protection performance.

Description

Technical field[0001]The present invention relates to the field of water supply pipe network and water supply hose, and more specifically, it involves an environmentally friendly water hose that does not increase the total organic carbon content in the water body.Background technique[0002]The total organic carbon (TOC) is the total amount of carbon containing organic matter in the water, so it can completely reactively reactively pollution of water pollution. Chemical oxygen demand (COD), biochemical oxygen demand (BOD) is a method of indirectly measuring organic matter in water, and all organics are composed of organic carbon, and the organic matter released in water is released from oxidation to form CO.2Therefore, TOC is a good method for directly measuring organic pollutants in water.[0003]The existing water supply pipe network and the water supply device are used to produce soft materials such as soft materials such as soft materials such as soft materials such as soft material...
