Abstract

The invention discloses a carboxylate polymer dispersant with a deforming function. The polymer is prepared through reactions between perfluorocarboxylic acid and a petroleum product namely polyoxyethylene. The dispersant is prepared by following steps: carrying out esterification reactions between perfluorocarboxylic acid and unsaturated polyoxyethylene monomers with terminal hydroxyl groups to prepare monomers with a deforming function; adding the monomers with a deforming function, isopentenyl polyoxyethylene, styryl polyoxyethylene, unsaturated carboxylic acid derivatives, and water into areactor to carry out free radical polymerization reactions for 4 to 5 hours at a temperature of 25 to 50 DEG C under the action of a redox initiator; and then adjusting the pH to 6.0-7.0 by a sodiumhydroxide water solution to obtain the dispersant. A fluorocarbon group with a strong deforming performance is introduced into highly water-soluble polyoxyethylene polymer; the dispersant can be applied to aqueous paints, cement mortar, ceramic, and gypsum, and the deforming function is enhanced.

Description

technical field [0001] The invention relates to the field of deep processing of downstream petroleum products, in particular to a carboxylate polymer dispersant with defoaming function prepared from polyoxyethylene and perfluorocarboxylic acid, a downstream petroleum product. technical background [0002] With the rapid development of society, the dependence of various industries on the petrochemical industry has increased. Modern transportation industry, metal processing, building materials industry, light industry, textile industry and booming electronics industry have put forward higher requirements for the deep processing of petroleum downstream products. Polyoxyethylene is a downstream product of petroleum, which can be used as a polyether nonionic surfactant, and can be used in household and industrial detergents, textiles, daily chemicals, oil exploration and oil refining surfactants and other fields. Polyether-type nonionic surfactants generally have higher water so...
