preparation example Construction

[0018] The invention relates to a building coating containing pearl clam shell powder and a preparation method thereof. The method comprises the following steps: 1) crushing pearl oyster shells first; 2) adding polyvinyl alcohol into hot water, stirring and dissolving to prepare polyvinyl alcohol aqueous solution for later use; 3) adding hydroxymethyl cellulose into water, stirring evenly, adding ammonia water, stirring Prepare a transparent viscous hydroxymethylcellulose aqueous solution for later use; 4) mix and stir the above-mentioned polyvinyl alcohol aqueous solution, hydroxymethylcellulose aqueous solution, fatty acid vinyl ester and vinyl acetate copolymer to form a latex slurry for later use; 5) mix the above-mentioned pearl oyster Shell powder or pearl clam shell powder is mixed with 68-78% of stone powder, 18-29% of latex slurry and 0.1-4% of formaldehyde to prepare the architectural coating containing pearl clam shell powder. The invention has good appearance decor...

Embodiment 1

[0028] Pulverize the pearl mussel shells in a ball mill. Take 0.4kg of polyvinyl alcohol and 4.8kg of water, first heat the water to 70°C, add the polyvinyl alcohol and stir until it completely dissolves into a transparent aqueous solution for later use. Get 0.8kg of hydroxymethylcellulose, 32kg of water, and 40g of ammonia water, add the hydroxymethylcellulose into water, stir evenly, add ammonia water, and make it dissolve into a transparent viscous solution for later use. Take 5kg of polyvinyl alcohol solution prepared above, 30kg of hydroxymethyl cellulose solution, 45kg of fatty acid acetate and vinyl acetate copolymer, 200kg of pearl shell powder, and 300g of formaldehyde and pour it into a mortar machine and stir at a low speed of 10 rpm Evenly pack the finished product.

Embodiment 2

[0030] The pearl clam shells are crushed by airflow. Take 0.4kg of polyvinyl alcohol and 5.6kg of water, first heat the water to 95°C, add the polyvinyl alcohol and stir until it completely dissolves into a transparent aqueous solution for later use. Take 1.2kg of hydroxymethylcellulose, 48kg of water, and 40g of ammonia water, add the hydroxymethylcellulose into water, stir evenly, add ammonia water, and make it dissolve into a transparent viscous solution for later use. Get 6kg of polyvinyl alcohol solution prepared above, 48kg of hydroxymethyl cellulose solution, 84kg of fatty acid acetate and vinyl acetate copolymer, 125kg of pearl shell powder, 500kg of stone powder, and 1kg of formaldehyde are poured into a mortar machine at 25 rpm. Minutes to stir evenly and pack the finished product.

Abstract

The invention discloses an architectural paint and preparing method with pearl case powder, which comprises the following steps: 1) grinding pearl case; 2) adding polyvinyl alcohol in the hot water; stirring to prepare the polyvinyl alcohol solution; 3) adding methylol cellulose in the water; stirring evenly to add ammonia; stirring to prepare transparent viscous methylol cellulose solution; 4) blending polyvinyl alcohol solution, methylol cellulose solution, aliphatic acid ethylene ester and vinyl acetate copolymer to form emulsion slurry; 5) mixing pearl case powder or pearl case powder and 68-78% stone powder, 18-29% emulsion and 0.1-4% formaldehyde to make the product.

Description

technical field [0001] The invention relates to a building coating containing pearl clam shell powder and a preparation method thereof. Background technique [0002] China is the first country in the world to discover and use pearls, and it is also the earliest country in the world that can be verified to cultivate pearls artificially. Pearl cultivation has a long history. With the increase in the production of freshwater pearls year by year, the pearl shells discarded after collecting pearls every year accumulate on the side of the collection field, which not only forms a huge source of pollution, but also seriously restricts the healthy development of the pearl block economy. Pearl shells are the mother body of pearls. The special structure and special optical effects of pearl shells can be used as raw materials for various novel functional materials, composite materials, and architectural decoration materials, and their application prospects are very broad. [0003] Arch...
