Abstract

The invention relates to a multifunctional PPR (polypropylene random copolymer) tube stock which comprises the following raw materials in mass percentage: 0.1-1% of functional master batch and the balance of PPR master batch. The preparation method comprises the following specific steps of: mixing the raw material and color master batch, loading in vacuum, drying raw materials, putting into a single-screw extruder, putting into a color line extruder, putting into a spiral die, and putting into a sizing sleeve, spraying in a vacuum setting tank, spraying in a cooking water tank, operating on an ink-jet printing machine, dragging by a caterpillar tractor, detecting the finished product and packaging into PPR tube stock specification. The multifunctional PPR tube stock disclosed by the invention is preferable in mechanical property, and high in stretching yield strength and anti-shock performance; the PPR tube is non-toxic and sanitary, convenient to mount and good in chemical resistance, and is especially good in hot welding performance.

Description

【Technical field】 [0001] The invention relates to the technical field of functional materials, in particular to a multifunctional PPR pipe and a preparation method thereof. 【Background technique】 [0002] With the rapid development of industry and the improvement of people's living standards, especially the awareness of health is also increasing. Because harmful bacteria are widely distributed in nature, and there are various types and large numbers, they seriously threaten human health. Diseases caused by bacterial transmission and infection have become a major social problem and have attracted widespread attention. Therefore, research on disinfectants is particularly important. Guanidine disinfectant is a type of disinfectant and antibacterial agent that has been widely used in recent years. It is easy to use and has a wide antibacterial spectrum, low toxicity, and no irritation. , It can also be used for the disinfection of fiber paper, food and daily necessities (towe...
