Abstract

The invention discloses a water-based environmentally friendly flame-retardant and heat-insulating coating and a preparation method thereof. The formula of the water-based environmentally-friendly flame-retardant and heat-insulating coating includes, in mass percentage: 20-40% of water-based acrylic emulsion, water-based epoxy resin emulsion 10-20%, water-based inorganic flame retardant dispersion slurry 20%-30%, water-based thermal insulation nano-dispersion slurry 5%-10%, water-based wetting and dispersing agent 0.1%-0.3%, water-based defoamer 0.1 %-1%, silane coupling agent 1%-3%, lead-free pigment 5%-10%, film-forming aid 0.5%-2.5% and deionized water 5%-25%. The water-based, environment-friendly, flame-retardant, heat-insulating and heat-insulating paint of the invention can form effective protection against corrosion, abrasion resistance, acid and alkali resistance, impact resistance, flame retardancy and fire prevention on the surface of the coated substrate. Under high-temperature combustion conditions, it does not produce harmful gases such as corrosive halogen gas, does not volatilize, has a long-lasting effect, is non-toxic, smoke-free, and does not drip.

Description

technical field [0001] The invention relates to the technical field of water-based flame-retardant and heat-insulating materials, in particular to a water-based environmentally friendly flame-retardant and heat-insulating coating and a preparation method thereof. Background technique [0002] With the development and progress of society, the improvement of people's living conditions and the pursuit of the concept of environmental protection and healthy life, water-based coatings are more and more popular with consumers due to their advantages of energy saving, environmental protection, health and safety, non-flammable and non-explosive, and very few volatile organic compounds. From architectural coatings to industrial anti-corrosion coatings to special coatings, the materials range from wood materials, plastic products, and the surface of steel structures. The application of water-based coatings has penetrated into various application fields with the ever-changing industrial ...
