Preparation method and construction technology of reflective and heat-insulating texture imitation granite water-based paint

Abstract

The invention discloses a production method and a construction process of a reflective and heat-insulating type texture imitating granite water-based paint, including: process 1, preparing a basic color paint; process 2, preparing a high-stability protective glue solution; process 3, granulating: process 1 The prepared base paint is mixed with the high-stability protective colloid solution prepared in the second step, and granulated by stirring or sieving process, so that the surface of the base paint particles forms a water-insoluble coating, and the particles that do not blend with each other The state exists in the high-stability protective colloid solution, forming colored particles; Step 4, deploying the finished paint: mixing and blending the colored particle components of various colors prepared after the granulation in Step 3 with silicone acrylic elastic acrylic emulsion to prepare The finished paint is obtained; step five, deploying fluorine-modified acrylic finish varnish. The coating produced by the invention is completely water-based, has the texture of natural granite, and has the function of reflection and heat insulation, and has high stain resistance, high elasticity, self-cleaning property, high weather resistance, and high cost performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method and a construction process of a granite-imitating water-based coating with reflection and heat insulation properties. Background technique [0002] The more popular imitation granite coatings in the market include two categories: [0003] (1) Oil-in-water type [0004] The oil-in-water type colorful paint is a kind of enamel paint of various colors, uniformly and stably dispersed in the aqueous solution containing the protective glue component, forming a complex two-phase system of oil and water. The continuous phase is water phase, which is synthetic resin emulsion, methyl protective colloid aqueous solution, etc.; the dispersed phase is oil phase, which contains solvent and nitro protective colloid, methyl styrene / butadiene copolymer, modified alkyd resin, etc. Membrane material, adding fillers, pigments and other additives. It not only has the high glo...

Problems solved by technology

[0008] As a result, various new energy-saving building materials have sprung up like bamboo shoots after rain. The most effective energy-saving material on the wall is the external wall insulation system. At present, there are mainly the following types: 1. Traditional polystyrene board external insulation or on-site spraying. Polyurethane foam insulation, in addition to construction troubles, also has fire safety hazards, so it is not as popular as it was a few years ago

2. Rock wool material has good thermal insulation effect, good air permeability, and good fire resistance, but its expensive cost, easy water permeability, and occupational injury of rock wool fiber to construction workers during on-site cutting make this product widely popularized boycotted

4. Reflective thermal insulation coating is an energy-saving and thermal insulation solution with low price and convenient construction, but the decorative effect of pure coating is very limited, and in order to meet the reflective thermal insulation effect, a uniform light-colored coating scheme has to be adopted, visually not effectively

[0009] Therefore, in addition to the defects of high cost, fire hazards, and non-environmental protection, the current external wall insulation system also lacks decoration and cannot meet people's requirements for the appearance of building facades; while ordinary imitation granite coatings have no reflection and heat insulation function, it does not contribute to the energy saving and emission reduction of buildings, and because it lacks the texture of natural granite, the decorative effect is limited
