Abstract

The invention discloses an acidizing fluid thickener synthetic process based on control of the reaction monomer ratio. The process comprises the following steps: (a) purifying a reaction monomer; (b) preparing an initiator liquor; (c) weighing 2-methyl-2-acrylamidyl propanesulfonic acid solid and dissolving the solid in distilled water; (d) adding acrylic acid and dimethyl diallyl ammonium chloride and controlling the content of dimethyl diallyl ammonium chloride with 11-13%, and dissolving adequately; (e) adjusting the pH value of the liquor; (f) shifting the mixed liquid for reaction to a reaction container, and stirring; (g) adding the initiator liquor; and (h) heating the reaction system for polymerization reaction for 4-5 hours to obtain a target product. According to the process provided by the invention, the acidizing fluid thickener can be successfully synthesized, and the synthetic process is simple in step, simple to operate, short in synthetic time, high in synthetic efficiency and low in synthetic cost. Performance parameters of the synthetic product are superior to those of current acidizing fluid thickener, and the intrinsic viscosity of the target product is improved by controlling the content of dimethyl diallyl ammonium chloride.

Description

technical field [0001] The invention relates to a synthesis process of acid liquid thickener based on controlling the ratio of reaction monomers. Background technique [0002] Thickener is a kind of rheological additive, which can not only thicken the coating and prevent sagging during construction, but also endow the coating with excellent mechanical properties and storage stability. It is a very important class of additives for water-based paints with low viscosity. [0003] At present, there are many kinds of thickeners available in the market, mainly including inorganic thickeners, celluloses, polyacrylates and associative polyurethane thickeners. Cellulosic thickeners have a long history of use and there are many varieties, including methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, etc., which used to be the mainstream of thickeners. The most commonly used of these is hydroxyethyl cellulose. Polyacrylate thickeners ca...
