Embodiment 1

[0032] The compounding ratio of the formula components in terms of parts by mass is: 87.5 parts of PVC-C resin, 12.5 parts of interpenetrating network copolymer formed by grafting of mildly chlorinated HDPE and acrylate, 0.5 part of silicone dispersant, no 4.8 parts of composite stabilizer containing heavy metal substances, 1.2 parts of lubricant, 2.7 parts of anti-aging agent;

[0033] The forming process uses the following work steps:

[0034] Step 1: Use medium-speed mixer C1 to pre-mix the composite stabilizer without heavy metal substances according to the component ratio, and weigh it for use after cooling;

[0035] Step 2, use the high and low speed mixer C2 to successively put in PVC-C resin, slightly chlorinated HDPE and the interpenetrating network copolymer formed by grafting of acrylate, and the organic silicon dispersant to stir evenly at a low speed, and continue to put in the composite stabilizer, Lubricants, anti-aging agents and other processing aids are mixe...

Abstract

The invention discloses a formula of PVC-C alloy material for a clean antibacterial direct drinking water home-entry branch pipeline and a forming technology. The formula comprises the following components in parts by mass: 85 to 92 parts of PVC-C resin, 8 to 15 parts of interpenetrating network copolymer formed by grafting lightly chlorinated HDPE and acrylate, 0.3 to 0.8 part of organic silicondispersant, 3 to 6 parts of composite stabilizer without heavy metal substances, 0.5 to 1.5 parts of lubricant and 2 to 4 parts of anti-aging agent. The raw materials and processing aids used in the formula do not contain lead, tin and cadmium heavy metal substances, and no heavy metal substances are dissolved out in the use process of the pipeline so that secondary pollution of the heavy metal substances to the direct drinking water pipeline is effectively eliminated. The PVC-C alloy formula material is suitable for extrusion processing of direct drinking water home-entry branch pipelines with the specification of DN15mm-DN80mm so that the antibacterial, clean, environment-friendly, sanitary, safe and other properties of the direct drinking water home-entry branch pipelines are comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of drinking water pipelines, and more specifically relates to a PVC-C alloy material formula and molding technology for clean antibacterial direct drinking water branch pipelines. Background technique [0002] As a new type of drinking water system, the pipeline direct drinking water system has great advantages such as hygienic and safe controllable, energy saving and environmental protection in operation, and healthy and convenient drinking. Therefore, it is very necessary to advocate urban sanitation and safe drinking water and to promote high-quality and healthy direct drinking water projects. While introducing the direct drinking water system, it is necessary to pay attention to the operation and maintenance of direct drinking water, to eliminate the secondary pollution of the pipeline in the water quality transportation process, and to make the direct drinking water project develop healthily and steadil...
