Polyether type phosphorus-free copolymer scale inhibitor

Polyether type phosphorus-free copolymer scale inhibitor

[Physical and chemical properties] The solid content is about 30%, light yellow transparent liquid

[Preparation method] Using acrylic acid (AA) and macromonomer allyl polyoxyethylene carboxylic acid (APEY) as raw materials, a polyether-type phosphorus-free copolymer scale inhibitor is prepared in the water phase by free radical polymerization.

(1) Synthesis of APEY

Allyl polyoxyethylene ether APEG and maleic anhydride MA were put into a three-necked flask, stirred at room temperature for 1.

(2) Synthesis of AA/APEY

In a multi-necked flask equipped with mechanical stirring, thermometer, reflux condenser, constant pressure funnel and nitrogen inlet, add APEY and distilled water according to a certain ratio.

[Performance] The scale inhibitor does not contain eutrophic elements such as phosphorus and nitrogen, and is an environmentally friendly scale inhibitor
