Description
Technical Field
The invention relates to the technical field of waterproof coiled materials, in particular to a water-based spraying and adhesion-maintaining high-molecular waterproof coating and a production device.
Background
In the fields of construction engineering, highway bridges, hydraulic engineering and the like, waterproof coatings are applied everywhere and play a vital role in protecting these structures from moisture attack. Conventional waterproof coatings are usually constructed by solvent or hot melting using asphalt, polyvinyl chloride, polyethylene, butyl rubber, and the like as base materials. However, these conventional waterproof coatings have some significant problems. First, they are difficult to construct and require specialized construction personnel and equipment, which greatly increases the complexity and cost of construction. Second, these coatings are environmentally poor and can release harmful Volatile Organic Compounds (VOCs) during production and use, which pose a threat to the environment and human health. Finally, they are poor in weather resistance, are easily aged and broken under environmental changes such as sunlight, heat, cold, humidity, etc., and are difficult to endure in waterproof effect.
In recent years, the water-based waterproof paint has been widely focused and applied due to the advantages of environmental protection, convenient construction and the like. The water is used as a dispersion medium, so that the use of harmful solvents can be reduced, the construction is simple, and the paint can be applied by brush coating or spraying. In addition, aqueous waterproof coatings generally have good adhesion and elasticity, and can be tightly adhered to various surfaces to form a durable waterproof layer. However, even aqueous waterproof coatings are not perfect. For example, since moisture in the paint evaporates during the construction and drying, fine cracks may be generated on the surface of the coating film, affecting the waterproof performance. In addition, the existing water-based waterproof paint has certain problems in terms of adhesive strength, weather resistance, crack resistance and the like, and the problems may affect the waterproof effect and the service life of the paint. Therefore, the invention provides the water-based spray-coating adhesive-holding high-molecular waterproof coating and a production device thereof.

In addition, the nano titanium dioxide is environment-friendly and does not generate harmful substances. The nano silane can improve the interfacial compatibility of the filler and the matrix, thereby improving the mechanical properties of the composite material. By improving the adhesion, the nano-silane can increase the water resistance and abrasion resistance of the coating. Nano graphene is a two-dimensional material with excellent mechanical properties and electrical conductivity. It can raise the hardness and scratch resistance of paint and endow paint with certain antistatic performance. In addition, the high thermal conductivity of the nanographene can improve the thermal stability of the coating.
Further, the plasticizer is any one or a mixture of more than one of naphthenic oil, cellulose, aromatic oil, pine tar and hydrophobically modified alkali swelling acrylic copolymer.
