Embodiment 1

[0013] Add 5 kg of polyurethane and 6.5 kg of rosin water into the reaction vessel, stir, and fully dissolve; add 0.5 kg of titanium dioxide and 0.2 kg of paraben into the reaction container, heat up to 80 ° C, stir, and react for 60 minutes; Add 1.5 kg of butyl acetate, 1.8 kg of propylene glycol methyl ether acetate, 0.2 kg of sodium polyacrylate, 0.75 kg of sodium dehydroacetate, 0.65 kg of xylene, 0.5 kg of tributyl tin chloride and 0.3 kg of Benzophenone was heated to 110° C., stirred, reacted for 4 hours, and cooled to obtain an anti-yellowing floor coating.

[0014] The construction method of the anti-yellowing floor coating in this example is: polishing with sandpaper → dust removal → smoothing the wall surface → roller coating of a thin layer of anti-yellowing floor coating → drying → roller coating of the second layer of anti-yellowing floor Coating, finishing by roller coating → dry naturally.

Embodiment 2

[0017] Add 55 kg of polyurethane and 60 kg of rosin water into the reaction container, stir and fully dissolve; add 10 kg of titanium dioxide and 1 kg of paraben into the reaction container, heat up to 90 ° C, stir, and react for 40 minutes; Add 20 kilograms of butyl acetate in the reaction vessel, 15 kilograms of propylene glycol methyl ether acetate, 12 kilograms of sodium polyacrylate, 5 kilograms of sodium dehydroacetate, 5 kilograms of xylene, 10 kilograms of tributyltin chloride and 4 kilograms Benzophenone is heated to 115° C., stirred, reacted for 3.5 hours, and cooled to obtain an anti-yellowing floor coating.

[0018] The construction method of the anti-yellowing floor coating of this embodiment includes the following steps: sanding paper polishing → dust removal → grinding the wall surface → roller coating of a thin layer of anti-yellowing floor coating → drying → roller coating of the second layer of anti-yellowing Change the floor coating, finish by roller coating...

Embodiment 3

[0021] Add 600 kg of polyurethane and 700 kg of rosin water into the reaction vessel, stir, and fully dissolve; add 75 kg of titanium dioxide and 30 kg of paraben into the reaction container, heat up to 85 ° C, stir, and react for 50 minutes; Add 250 kilograms of butyl acetate in the reaction vessel, 200 kilograms of propylene glycol methyl ether acetate, 150 kilograms of sodium polyacrylate, 100 kilograms of sodium dehydroacetate, 800 kilograms of xylene, 75 kilograms of tributyl tin chloride and 50 kilograms Benzophenone is heated to 1120° C., stirred, reacted for 3 hours, and cooled to obtain an anti-yellowing floor coating.

[0022] The construction method of the anti-yellowing floor coating of this embodiment includes the following steps: sanding paper polishing → dust removal → grinding the wall surface → roller coating of a thin layer of anti-yellowing floor coating → drying → roller coating of the second layer of anti-yellowing Change the floor coating, finish by rolle...

Abstract

The invention discloses an anti-yellowing terrace coating and a construction method thereof. The anti-yellowing terrace coating is prepared from the following raw materials in parts by weight: 50-60 parts of polyurethane, 60-70 parts of rosin water, 15-25 parts of butyl acetate, 15-20 parts of propylene glycol 1-monomethyl ether 2-acetate, 8-15 parts of sodium polyacrylate, 5-10 parts of sodium dehydroacetate, 5-8 parts of xylene, 5-10 parts of tributyl tin chloride, 3-5 parts of benzophenone and 1-3 parts of nipalgin; the construction method of the anti-yellowing terrace coating sequentially comprises the following steps: polishing with abrasive paper, dedusting, puttying, rubbing down a wall surface, roll-painting a thin layer of anti-yellowing terrace coating, airing, roll-painting a second layer of anti-yellowing terrace coating, carrying out roll-painting finishing and naturally airing. The anti-yellowing terrace coating is excellent in anti-yellowing property and is still purely white after being painted for multiple years.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an anti-yellowing floor coating and a construction method thereof. Background technique [0002] Floor coatings were first invented in Germany in 1934 and are mainly made of oil, tree materials, colors, and solvents. According to the film-forming substances, floor coatings include epoxy resin floor coatings, polyurethane resin floor coatings, unsaturated polyester resin floor coatings, acrylic floor coatings, crystal floor coatings, and polyurea elastomer floor coatings. Coatings, concrete sealing and curing agents, etc. Polyurethane floor coatings are high-solid thick coatings, which have excellent corrosion resistance, insulation properties, acid and alkali salt resistance, high strength and elasticity, and the ground coated with polyurethane floor coatings is smooth and non-slip, elastic Good, wear-resistant, pressure-resistant, water-resistant, beautiful and elega...
