Problems solved by technology

There have been a lot of research in this area, but the effect of monomers with single and double functional groups is not very good, and the comprehensive performance and effect are not significant enough.
This leads to an increase in usage, which also increases the cost

Embodiment 1

[0020] Put 30 g of malic acid at 90°C, pass through N 2 After heating to melt, add 0.3 g of dibutyltin dilaurate; vacuumize to 0.04 Mpa, react for 4 h; vacuum dry at 60°C to obtain 30 g of white solid powder. The white powder is dissolved in pure water at 30-40% by mass to obtain a concentrated antiscalant solution, which is diluted 11 times with pure water before use, and it is biodegradable dendritic antiscalant A.

Embodiment 2

[0022] Put 30 g of malic acid at 110°C, 2 protection, heating to melting, adding 0.3 g of dibutyltin dilaurate; vacuuming to 0.04 Mpa, reacting for 5 h; at 60°C, vacuum drying to obtain 28.5 g of white solid powder, which was mixed according to 30% by mass Dissolve ~40% in pure water to obtain concentrated solution of antiscalant, dilute 11 times with pure water before use, it is biodegradable dendritic antiscalant B.

Embodiment 3

[0024] Put 30 g of malic acid at 120°C, 2 protection, heating to melting, adding 0.3 g of n-butyl titanate; vacuuming to 0.04 Mpa, and reacting for 6 h; at 60°C, vacuum drying to obtain 28.9 g of white solid powder. ~40% is dissolved in pure water to obtain a concentrated antiscalant solution, which is diluted 11 times with pure water before use. It is a biodegradable dendritic antiscalant C.

Abstract

The invention relates to high polymer material modification technical field, and particularly relates to a new biodegradable dendritic scale inhibitor. The biodegradable dendritic scale inhibitor is a dendritic polymer scale inhibitor, and has the advantages of low adding amount, high scale inhibition performance, low production cost, industrialization promotion, biodegradation, no pollution to environment, simple post processing and the like.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to a biodegradable dendritic scale inhibitor. Background technique [0002] Scale inhibitor is a polymer containing ether bond, carboxyl group, amine group, sulfonic acid group, phosphine group, hydroxyl group, etc. It has certain scale inhibition and dispersion ability for various scales, and has certain corrosion inhibition performance. Adding antiscalant for antiscaling treatment is one of the relatively convenient and efficient methods among many antiscaling methods. [0003] Among the numerous antiscalants, non-toxic, less polluting, and environmentally acceptable water treatment agents are in increasing demand. Most of these antiscalants are polymer antiscalants, and many of them have been put into industrial production. But the problem of small molecular weight generally exists. However, polymer scale inhibitors, due to their special symmetrical struct...
