Reverse osmosis scale inhibitor and preparation process thereof

Abstract

The invention discloses a reverse osmosis scale inhibitor and a preparation process thereof. The scale inhibitor is prepared from the following composition ingredients in parts by weight: 32 to 38 parts of sodium hexametaphosphate, 4 to 8 parts of hydrolytic polymaleic anhydride, 2 to 6 parts of sodium dodecyl benzene sulfonate, 3 to 7 parts of mercaptobenzothiazole, 2 to 8 parts of hexadecyl dimethyl benzyl ammonium chloridecetyl dimethyl benzyl ammonium chloride, 15 to 19 parts of polyepoxysuccinic acid, 4 to 10 parts of zinc sulfate, 1 to 5 parts of isopentane, 3 to 7 parts of 2-acrylamido-2-methylpropanesulfonic acid-acrylic acid multipolymersacrylic acid-2-acrylamide-2-methylpropanesulfonic acid multicomponent copolymers, 6 to 12 parts of sodium carbonate, 3 to 7 parts of copper corrosion inhibitors, 8 to 12 parts of reverse osmosisreverse penetrating agents, 100 to 120 parts of ethanol and 88 to 98 parts of deionized water. A good scale inhibition effect can be achieved; good effects of inhibiting water scale generation and peeling old scales can be achieved; the scale inhibition performance is excellent; the reverse osmosis effect is achieved; the effect is and obvious; safety and reliability are realized. Meanwhile, the preparation process is simple and scientific; the implementation is easy; the cost is low; the reverse osmosis scale inhibitor is applicable to industrialized popularization and the like.

Description

technical field [0001] The invention relates to the technical field of scale inhibition, in particular to a reverse osmosis scale inhibitor and a preparation process thereof. Background technique [0002] Scale inhibitors are a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation and scaling of insoluble inorganic salts on metal surfaces, and maintain good heat transfer effects on metal equipment. The anti-corrosion and anti-scaling agent for cold-changing equipment is formulated with epoxy resin and specific amino resin as the base material, adding appropriate amount of various anti-rust, anti-corrosion and other additives, and is a single component. It has excellent shielding, anti-seepage, anti-rust properties, good scale resistance, thermal conductivity, excellent resistance to weak acids, strong alkalis, organic solvents, etc. It has strong adhesion, and the film layer is bright, flexible, dense, and hard. . ...

Problems solved by technology

[0004] However, the existing scale inhibitors are usually difficult to maintain a relatively consistent scale inhibition efficiency under different pH conditions, and the reverse osmosis ability is weak, etc.
