Abstract

The invention relates to a single-component quick-drying and quick-hardening type polymer cement waterproof coating and a use method thereof. The polymer cement waterproof coating is prepared from the following raw materials in parts by weight: 30-55 parts of 42.5-level polymer cement waterproof coating, 25-60 parts of 40-200-mesh quartz sand, 0-15 parts of 320-mesh coarse whiting, 5-15 parts of polyacrylate copolymer latex powder, 6-10 parts of anhydrous sodium sulphate, 1-3 parts of water glass, 0.05-1 part of a water repellent, 0.05-0.3 part of an early strength agent, 0.05-0.25 part of a retarder, 0.5-2 parts of calcium oxide, 0.05-0.3 part of cellulose ether, 0.05-0.5 part of a powdery water reducing agent and 0.05-0.3 part of a powdery defoaming agent. By virtue of the single-component quick-drying and quick-hardening type polymer cement waterproof coating, the construction speed is greatly increased, the construction period is greatly shortened, the problems that a waterproof coating film is low in early strength and falls after being soaked in water are solved; and furthermore, by utilizing a single-component powder packaging manner, the polymer cement waterproof coating can be stored and transported at a low temperature.

Description

(1) Technical field [0001] The invention belongs to the technical field of waterproof materials for buildings, and in particular relates to a single-component quick-drying and quick-hardening polymer cement waterproof coating and its application method. (2) Background technology [0002] Polymer cement waterproof coating has the characteristics of good working performance, excellent waterproof and anti-seepage performance, strong adhesion to the base layer, and good durability. It is a water-based environmental protection material and is usually used in waterproof and moisture-proof projects for buildings. However, traditional polymer-modified cement-based waterproof materials cannot meet the requirements of rapid construction. After construction and brushing, it is necessary to wait until the cement has solidified for 3 days before the water storage test can be carried out. After the acceptance, the next process can be carried out. Moreover, traditional polymer cement water...
