Embodiment Construction

[0017] The present invention will be further described below in conjunction with embodiment.

[0018] First, some raw materials are introduced as follows:

[0019] Anionic neoprene latex, available in the market, requires a glass transition temperature of -10 degrees, a viscosity of 800, a solid content of about 57%, and a minimum film-forming temperature of -20°;

[0020] Quartz powder: also known as silica powder, quartz powder is a hard, wear-resistant, chemically stable silicate mineral, its main mineral component is SiO2, the fineness is 100 mesh-150 mesh, SiO2≥99-99.5%, available in the market;

[0021] Sulfur-aluminum cement: Sulphoaluminate cement is anhydrous calcium sulphoaluminate (C4A3S) and dicalcium silicate ( C2S) is a clinker mainly composed of minerals, mixed with an appropriate amount of mixed materials (gypsum and limestone, etc.) Divided into 5 varieties such as rapid hardening sulfoaluminate cement, high-strength sulfoaluminate cement, expansive sulfoal...

Abstract

The invention relates to the technical field of waterproof materials, in particular to a method for implementing a cement-based spraying and rapid hardening water-borne waterproof coating. The methodcomprises the following steps: a, injecting an anionic neoprene latex into a mixing reaction kettle, performing stirring at the normal temperature, slowly adding water, a wetting dispersant and a defoamer, and performing uniform stirring to prepare a first auxiliary; b, adding sulfur aluminum cement and portland cement powder mixing stirrer, then adding quartz powder, cellulose ether and dispersible latex powder at different times, and uniformly stirring the raw materials to prepare a second auxiliary; c, spraying the first auxiliary and the second auxiliary onto the surface of a building according to the spray amount ratio of 1:2 to form the cement-based spraying and rapid hardening water-borne waterproof coating. The cement-based spraying and rapid hardening water-borne waterproof coating has a very high condensation speed, can be condensed firmly within 15 min and cannot drop off or be stripped off a base plane.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to an implementation method of a waterproof coating layer. Background technique [0002] In the prior art, there are many implementation methods for the waterproof material layer, but there are generally disadvantages such as long setting time, low bonding strength, poor waterproof effect, not suitable for waterproof surface construction of some special structures, and cannot meet the requirements of some constructions. . Contents of the invention [0003] The purpose of the present invention is exactly to above-mentioned shortcoming, provides a kind of setting speed faster, the implementation method of cement-based spraying quick-setting water-based waterproof coating layer with higher bonding strength. [0004] The technical scheme of the present invention is achieved in that a kind of implementation method of cement-based spraying quick-setting water-based waterpr...
