Abstract
The application discloses a composite heat-insulating water-based waterproof coating, and belongs to the technical field of waterproof coatings. The preparation method of the composite heat-insulating water-based waterproof paint comprises the following steps: adding the liquid into a stirring tank, stirring for 20min at 400r/min, adding the auxiliary agent, stirring for 20min at 500r/min, adding the powder, stirring for 30min at 700r/min, filtering, and sealing. The single-component polymer waterproof paint is prepared from polymer emulsion, neoprene latex, inorganic powder and various auxiliary agents in scientific proportion, and the polymer emulsion, the neoprene latex and the inorganic powder form a coating film with certain elasticity after construction, so that the waterproof paint with better heat insulation and waterproof effects is achieved.
Description
Technical Field
The application belongs to the technical field of waterproof coatings, and particularly relates to a composite heat-insulating water-based waterproof coating.
Background
The water leakage phenomenon of most of metal roofs of steel structures, color steel plates and the like in China is serious, the water leakage phenomenon is more prominent in the south and north areas of China, and the water leakage is mainly concentrated at joint positions such as gutter, vertical lap joint, horizontal lap joint, ridge two-side lap joint, daylighting tile periphery, fan periphery, chimney pipeline periphery, all screws of the roofs, water tanks, parapet wall joints and the like. The main reasons for the phenomenon are various, and besides the problems of construction technology and steel structure materials, the leakage caused by deformation of the joint of the steel structure due to overlarge temperature difference is caused; the structure is deformed under the action of external forces such as wind load, snow load and the like, and the linked part is displaced to cause leakage; the problem of waterproof materials which deform and leak when the loading stress is asynchronous is also an important reason for special parts such as roof light-collecting belts.
The JS composite heat-insulating water-based waterproof paint developed in the project is Ca (OH) generated by reaction when the polymer emulsion and cement are stirred and the cement is hydrated in water 2 The concentration of the solution can reach saturation rapidly and precipitate hydrated crystal, and at the same timeEttringite crystals and hydrated calcium silicate gels are formed and polymer particles in the emulsion deposit on the surface of the gel. Along with the progress of hydration reaction, the deposition amount of polymer particles is increased more and more, and a compact stacking layer is formed on the surface of gel and on the cement particles which are not hydrated completely, so that the polymer particles are further expanded into a continuous film, and a network structure which is mutually cemented with hydrated cement paste is formed. The structure can greatly improve the physical tissue structure of the cement mortar hardened body, relieve the internal stress, reduce the generation of microcracks and strengthen the compactness and mechanical property of the polymer waterproof coating. The product coating film has stronger tensile strength and bonding strength, has stronger adaptability to various deformation and dislocation of the metal roof caused by external environment, and can effectively ensure the waterproof effect.
The product can be widely applied to waterproof coatings of metal roofs and the like.

Emulsion polymerization a polymerization process in which an initiator and an emulsifier are added to water to disperse monomers under vigorous stirring. The method has high polymerization speed and is easy to obtain polymer with high polymerization degree, namely emulsion polymer. The polymer particles are much smaller than in suspension polymerization, resulting in a stable emulsion. Polymer emulsions are heterogeneous systems in which the polymer is in a particulate, irregularly dispersed state in the emulsion. The emulsion particles and their distribution are greatly different due to the different emulsifiers and polymerization processes used in the emulsion polymerization process. Emulsion particle size and its distribution are directly related to the appearance of the emulsion, so that different emulsions have different appearances, mainly in hue.
