Abstract

The invention discloses a low-alkali scale inhibitor and a preparation method thereof. The low-alkali scale inhibitor is prepared from the following components in parts by mass: 40 to 55 parts of petroleum sodium sulfonate, 45 to 55 parts of imidazoline phosphate, 20 to 40 parts of a solvent, 10 to 15 parts of a bactericide, 10 to 20 parts of an antiseptic, 5 to 10 parts of graphene oxide, 0.1 to0.15 part of an amide surfactant and 0.01 to 0.04 part of a dispersant. The low-alkali scale inhibitor disclosed by the invention is good in dispersity, low in toxicity and good in compatibility of substances, has the characteristics of high temperature resistance, chloride resistance and low cost, can remove scale attached to a pipeline and effectively prevent the scale from being attached to thepipeline again, can be used for corrosion prevention and sterilization, produces a fresh-keeping effect on water equipment and the pipeline, does not contain inorganic phosphorus, and is safe and healthy.

Description

technical field [0001] The invention relates to a scale inhibitor and a preparation method thereof, in particular to a low-alkali scale inhibitor and a preparation method thereof, belonging to the field of water treatment. Background technique [0002] In the prior art, the building tap water supply process is that the water supply plant passes the water through the water pump, and sends the water from the water supply pipe network to the faucets (ie water pipes) provided to each user, so that each household can use the water source. When the water supply network uses a section After a period of time, scale will adhere to the pipe wall of each water supply pipeline, which will lead to the growth of bacteria, causing users to have doubts about hygiene when using water. [0003] The composition of scale is relatively complex, and can be roughly divided into two types: hard scale and soft scale according to its formation reasons and forming states. When the water contains impur...
