Abstract

The invention relates to a plant extract composite scale and corrosion inhibitor which comprises the following ingredients in parts by weight: 3-5 parts of olive leaf extract, 10-15 parts of persimmonextract, 3-5 parts of pumpkin extract, 6-8 parts of carrot extract, 1-2 parts of radix astragali extract, 20-30 parts of sodium alginate and 50-60 parts of ATMP (amino trimethylene phosphonic acid).In the plant extract composite scale and corrosion inhibitor, the persimmon extract with ionic adsorption and the anti-bacterial and anti-oxidative radix astragali extract are selected for compoundingthe olive leaf extract, the pumpkin extract and the carrot extract that have the functions of slow release and scale inhibition, and corresponding beneficial effects are extracted by selecting different extraction methods according to respectively functions, so that the scale and corrosion inhibitor has excellent functions of scale inhibition and slow release; in addition, the scale and corrosioninhibitor is good in product stability, so that the scale and corrosion inhibitor can be preserved and used for a long time.

Description

technical field [0001] The invention relates to a plant extract composite scale and corrosion inhibitor and a preparation method thereof, belonging to the field of water treatment agents. Background technique [0002] As an important class of pharmaceuticals, water treatment agents are widely used in water treatment. Natural polymers such as lignin, starch, cellulose, and tannin can be used as water treatment agents. Natural polymers have a wide range of sources, are non-toxic, and are easy to grow. degradation. The active ingredients are directly extracted from natural substances as scale and corrosion inhibitors, which have outstanding performance, are non-toxic and non-polluting, and are convenient and simple in subsequent treatment, which can reduce many unnecessary troubles. At present, the research on the performance of natural plant extracts has gradually become a research hotspot in water treatment agents. For example, the areca nut extract extracted from betel nut...
