Embodiment 1

[0055] Add 20Kg of water into the stirring tank, add 1.5Kg of dispersant hydrophobic polycarboxylate sodium salt under stirring, stir and mix evenly, then add 15Kg of titanium dioxide and 28Kg of flame retardant aluminum hydroxide in turn, increase the speed to 1200-1500 rpm / min, stirring for 20-30 minutes. After stirring and mixing evenly to form a slurry, it is sent to a sand mill for grinding until the particle size is 50-60 microns. Put the ground slurry into the paint mixing kettle, stir at 600-800 rpm, then add 28Kg of acrylate polymer and 2Kg of inorganic nanomaterial nano-calcium carbonate, and stir for 10-20 minutes. Then add 1.8Kg of film-forming aid pentylene glycol monoisobutyrate, 0.4Kg of organic silicon defoamer and 1.5Kg of compound antifungal agent composed of Mydi 1011 and isothiazolinone. Stir for another 20 to 30 minutes, then add 1.8Kg of associative polyurethane thickener and 2Kg of nano-modified coating film enhancer nano-hydrophobic liquid silica, con...

Embodiment 2

[0057]Add 10Kg of water into the stirring tank, then add 2Kg of dispersant hydrophobic polycarboxylate potassium salt and stir for 8-10 minutes, then add 10-12Kg of titanium dioxide and 20Kg of flame retardant aluminum hydroxide in turn, increase the speed and continue stirring. After stirring and mixing evenly to form a slurry, grind to a particle size of 50-60 microns. Put the ground slurry into the paint mixing kettle, adjust the rotation speed to 500-600 rpm for stirring, then add 40Kg of acrylate polymer and 0.5Kg of inorganic nanomaterial nano-titanium dioxide, and stir for 30-40 minutes. Then add 1.2Kg of film-forming aid alcohol ester-12, 0.6Kg of defoamer and 2.0Kg of mildew 1011 antifungal agent, and stir for 30 to 40 minutes. Then add 1.2-1.5Kg of polyurethane thickener and 1-1.2Kg of nano-modified coating film enhancer nano-hydrophobic liquid aluminum oxide, stir and mix evenly, adjust the viscosity to 90-110 seconds (using the Torrfield viscosity method), filter ...

Embodiment 3

[0059] Add 30Kg of water into the stirring tank, add 1Kg of dispersant mixture of hydrophobic polycarboxylate potassium salt and sodium salt under stirring, stir for 2-3 minutes, then add 18-20Kg of titanium dioxide and 40Kg of flame retardant borax in sequence, and stir After mixing evenly to form a slurry, send it to a sand mill to grind to a particle size of 40-50 microns. Add the ground slurry into the paint mixing kettle, stir and mix, then add 20-23Kg of acrylate polymer and 3-3.5Kg of inorganic nano-material nano-montmorillonite, stir for 20-30 minutes, and then add 2.5Kg of film-forming assistants in sequence Add ethylene glycol n-butyl ether, 0.2Kg polyether defoamer and 1Kg compound antifungal agent composed of No. 75 antifungal agent, Mydi 1011 and isothiazolinone, and stir for 20 to 30 minutes. Then add 2.0-2.5Kg of associative polyurethane thickener and 2.5-3Kg of nano-modified coating film enhancer, a mixture of nano-hydrophobic liquid silicon dioxide and aluminu...

Abstract

The invention relates to mildewproof flame-retardant tunnel decoration paint, a preparation method and application thereof. The paint comprises the following components in parts by mass: 10 to 30 parts of water, 1.0 to 2.0 parts of dispersant, 1.0 to 2.0 parts of antimildew agent, 10 to 20 parts of titanium dioxide, 20 40 parts of flame retardant, 20 to 40 parts of acrylic ester polymer, 1.0 to 3.0 parts of nanometer modified coating reinforcing agent, 1.2 to 2.5 parts of film-forming additive, 0.2 to 0.6 parts of defoamer, 1.2 to 2.5 parts of polyurethane thickener, and 0.5 to 3.5 parts of inorganic nano-materials. The preparation method mainly comprises the steps of adding needed components under certain conditions, uniformly mixing or grinding the components, adding the needed component in turn, uniformly mixing all raw materials and then adjusting the mixture to have appropriate viscosity. The paint is applied to the decoration of tunnels, aboveground buildings and underground buildings, and has the characteristics of fire prevention, flame retardancy, mildewproof property, waterproof property, moisture-proof property, high adhesion, non-shedding property, strong resistance tohigh-pressure water impact, long lifespan and the like.

Description

Technical field [0001] The invention relates to a mildew-proof and flame-retardant coating and its preparation method and application, in particular to a mildew-proof and flame-retardant decorative coating for tunnels, above-ground buildings and underground buildings, its preparation method and application. Background technique [0002] In recent years, with the development of my country's economic construction, various tunnels, above-ground buildings and underground buildings have been increasing. Tunnels not only undertake the task of transportation, but also function as channels for optical cables, cables, and even oil pipelines and water pipelines. At the same time, with the continuous increase of long tunnels and extra-long tunnels in our country, the layered fireproof, mildew-proof and flame-retardant protective decoration of tunnel structures has become an important research topic. safety factor in . People pay more and more attention to the fire safety of above-gro...
