Abstract

The invention discloses a preparation method of a high-temperature-resistant amidoalkyl hyperconcentrated emulsion polymer. The polymer is mainly prepared from the following materials: 1.5 to 3.0 parts of a hydrophilic small monomer for emulsification, 2.5 to 3.5 parts of a hydrophobic small monomer for emulsification, 10 to 35 parts of an amide small monomer, 0.04 to 0.18 part of an emulsion initiator, 2.5 to 4.9 parts of an initiator a, 3.3 to 5.6 parts of an initiator b, 380-420 parts of an alkyl small monomer, 6.6-8.9 parts of a cross-linking agent, 4.5-7.2 parts of a flexible small monomer, 25-42 parts of a fluorine functional monomer, 0.08-0.30 part of a chain transfer agent, 5-10 parts of a neutralizer, 5-10 parts of a pH regulator, 3.0-9.0 parts of a co-emulsifier and 0.6-1.8 partsof a liquid film enhancer, with the balance being water, wherein the total mass part of the polymer is 1000, and the solid content of the polymer is 50%. The hyperconcentrated emulsion polymer is formed by polymerizing the amide small monomer and the alkyl small monomer through a hyperconcentrated polymerization method; a jelly-like hyperconcentrated emulsion is prepared through the hyperconcentrated emulsion polymerization method and used for a polymerization reaction; and the hyperconcentrated emulsion has the characteristic of good stability, and the formed hyperconcentrated emulsion polymer also has very excellent stability.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to the field of waterproof materials, in particular to a method for preparing a high-temperature-resistant amidoalkyl ultra-concentrated emulsion polymer. Background technique [0002] The synthesis reaction of polymer emulsion is a polymerization process in which monomer and water are configured into an emulsion under the action of an emulsifier. The synthesis of polymer emulsions is one of the stricter synthesis methods. Before large-scale production of polymer emulsions, strict pilot tests are required. Especially, thermally induced polymer emulsion synthesis experiments require high temperature control. Under automatic operation conditions, the influence of human factors will inevitably affect the reaction process of the pilot test synthesis, such as the dropping time and dropping speed of the pre-emulsified monomer, the temperature control in the reactor, the temperatur...
