Abstract
The invention 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 coating comprises the following steps: adding the liquid material into a stirring tank, stirring at 400r/min for 20min, adding the auxiliary agent, stirring at 500r/min for 20min, finally adding the powder material, stirring at 700r/min for 30min, filtering, and sealing. The polymer emulsion, the neoprene latex, the inorganic powder and the various auxiliary agents are scientifically proportioned to prepare the single-component polymer waterproof coating, and after construction, the polymer emulsion, the neoprene latex and the inorganic powder form a coating film with certain elasticity, so that the waterproof coating achieves better heat insulation and waterproof effects.
Description
Technical Field
The invention 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 steel structures, color steel plates and other metal roofs in China is serious, the phenomenon exists in the south and north areas of China, the south is more prominent, and the water leakage is mainly concentrated at seam positions such as a gutter, a vertical lap joint, a horizontal lap joint, a ridge both-side lap joint, a lighting tile periphery, a fan periphery, a chimney pipeline periphery, all roof bolts, a water tank, a parapet wall seam and the like. The main reasons for this phenomenon are many, and besides the problems of construction process and steel structure material, the leakage caused by deformation of the steel structure joint due to excessive 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 generates displacement to cause leakage; the problem of waterproof materials which are deformed to cause leakage when the load stress is asynchronous at special parts such as roof lighting strips is also an important reason.
The JS composite heat-insulating water-based waterproof coating researched and developed by the project is Ca (OH) generated by the reaction of high-molecular emulsion and cement when the cement is hydrated in water after being stirred 2 The concentration of the solution can quickly reach saturation, hydrated crystals are separated out, meanwhile, ettringite crystals and hydrated calcium silicate gel are generated, and polymer particles in the emulsion are deposited on the surface of the gel. With the progress of hydration reaction, the deposition amount of the polymer particles is more and more, and a compact accumulation layer is formed on the surface of the gel and the cement particles which are not completely hydrated, so that the gel is expanded into a continuous film to form a network structure mutually cemented with the hydrated cement slurry. The structure can greatly improve the physical organization structure of the cement mortar hardened body, relieve the internal stress, reduce the generation of microcracks and enhance the compactness and the mechanical property of the polymer waterproof coating. The coating film has strong tensile strength and bonding strength depending on the product, has strong adaptability to various deformations and malpositions of the metal roof caused by the external environment, and can effectively ensure the waterproof effect.
The product can be widely applied to waterproof coatings of metal roofs and the like.
For example, chinese patent, application No.: CN201710144392.2 discloses a high molecular polymer emulsion, a preparation method thereof and a waterproof coating prepared by using the same, and the technical scheme is as follows:
"the first object of the present invention is implemented by the following technical means: a high molecular polymer emulsion comprises the following components in parts by mass: 0.1-2 parts of neoprene latex, 3-4.3 parts of butyl latex, 45-49 parts of ethyl acrylate latex, 15-17 parts of siloxane emulsion, 4-6 parts of dibutyl phthalate, 0.045-5 parts of anionic surfactant, 2-3.4 parts of polyvinyl alcohol, 18-22 parts of polysiloxane, 19-21 parts of sodium hydroxide and 0.2-1 part of auxiliary agent.

Emulsion polymerization the initiator and emulsifier are added into water to disperse the monomers, and the polymerization process is carried out under vigorous stirring. The method has high polymerization speed, and is easy to obtain polymers with high polymerization degree, namely emulsion polymers. The polymer particles are much smaller than in the suspension polymerization process and can form stable emulsions. The polymer emulsion is a heterogeneous system, and the polymer is in a granular irregular dispersion state in the emulsion. Because the emulsifier and the polymerization process adopted in the emulsion polymerization process are different, the generated emulsion particles and the distribution thereof are greatly different. The emulsion particle size and its distribution are directly related to the appearance of the emulsion, so that different emulsions have different appearances, mainly expressed in hue.
