Abstract

The invention provides a polymer water-proofing agent and a preparation method and a usage method thereof, relates to a water-proofing agent and a preparation method and a usage method thereof and aims at solving the problem that a macromolecular polymer water-proofing material is instable under strong base condition and is invalid when being mixed with ordinary concrete and mortar. The water-proofing agent is prepared from a methyl ester monomer, a butyl ester monomer, an acrylic monomer, styrene, an assistant, a coupling agent, an initiator, an emulsifier, a protection agent, a buffering agent, calcium lignosulphonate, triethanolamine, acrylonitrile and water. The preparation method comprises the steps that the emulsifier, the protection agent, the buffering agent and water are added to a reactor, stirring and heating are performed; a part of initiator is added, heating is performed, the mixed monomer of the methyl ester monomer, the acrylic monomer, the butyl ester monomer, the styrene, the acrylamide and the acrylonitrile is added for heat preservation; the residual mixed monomer and the coupling agent are added; the assistant, the calcium lignosulphonate, the triethanolamine and the initiator are added, and heating is performed; temperature reduction is performed for discharging. The polymer water-proofing agent is used in the field of building water proofing.

Description

technical field [0001] The invention relates to a waterproofing agent and its preparation method and application method. Background technique [0002] There are a large number of capillary pores and hydrophilic hydroxyl groups inside the concrete material, which are easy to absorb water in a humid environment, causing frost damage; at the same time, harmful substances such as chloride ions will also enter the material with water, accelerating the corrosion of steel bars in reinforced concrete. Soluble salt in concrete is prone to water-soluble migration, forming salt frost on the surface of the building, affecting the appearance of the building. Therefore, waterproofing the concrete has a positive effect on strengthening and improving the performance of the concrete mechanism and prolonging the service life. [0003] Currently commonly used waterproof materials are mainly divided into two types, rigid waterproof and flexible waterproof. Among them, the commonly used rigid ...
