Embodiment 1

[0033] The preparation method of a kind of photocatalytic self-cleaning environmental protection coating of the present embodiment comprises the following steps:

[0034] (1) Mix 80g waste marble powder, 50g hollow glass microspheres, 30g titanium hydride and 30g sodium peroxide in ethanol and stir for 0.5h.

[0035] (2) Add 10g of tin powder and 10g of antimony iodide in sequence and continue mixing and stirring for 0.5h.

[0036] (3) Put the mixed liquid into the polytetrafluoroethylene lining after soaking in aqua regia for 1 hour and distilling and boiling for 3 times, then place the lining in the matching cylinder and tighten it.

[0037] (4) The whole reaction kettle was placed in a constant temperature reactor and reacted at 150°C for 3 hours.

[0038] (5) After the reaction, all the products were centrifuged at a speed of 6000r / min, and the precipitate was taken, washed with deionized water, and then dried to obtain a powder.

[0039] (6) Take 80g of the final powder...

Embodiment 2

[0052]The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. In this embodiment, 100g of waste marble powder, 80g of hollow glass microspheres, 50g of titanium hydride and 45g of sodium peroxide were mixed and stirred in ethanol for 1 hour, and then 20 grams of tin powder and 15 grams of antimony iodide were added successively and continued to mix and stir for 1 hour . Put the mixed liquid into the polytetrafluoroethylene liner soaked in aqua regia and distilled and boiled, and then place the secondary liner in the matching cylinder and tighten it. The whole reaction kettle was placed in a constant temperature reactor, and reacted at 250° C. for 7 hours. After the reaction, all the products were centrifuged at a speed of 8000r / min, and the precipitate was collected, washed with deionized water, and then dried to obtain a powder...

Embodiment 3

[0054] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. In this example, 90g of waste marble powder, 65g of hollow glass microspheres, 40g of titanium hydride and 35g of sodium peroxide were mixed and stirred in ethanol for 0.75h, and then 15g of tin powder and 20g of antimony iodide were added successively to continue mixing Stir for 0.75h. Put the mixed liquid into the polytetrafluoroethylene liner soaked in aqua regia and distilled and boiled, and then place the secondary liner in the matching cylinder and tighten it. The whole reaction kettle was placed in a constant temperature reactor and reacted at 200°C for 5h. After the reaction, all the products were centrifuged at a speed of 6000r / min, and the precipitate was collected, washed with deionized water, and then dried to obtain a powder. Take 90g of final powder an...

Abstract

The invention discloses a photocatalytic self-cleaning environment-friendly paint and a preparation method thereof. The paint is prepared by a hydrothermal method, and a post crystallization treatment is required. The prepared powder has the advantages of narrow particle size distribution, low agglomeration degree, pure components, small pollution during the preparation process, and easiness for industrial production. Moreover, the particle size of the powder can be adjusted by controlling the reaction conditions. The preparation technology is simple, and the equipment is cheap. The particle size of powder can be controlled by controlling the reaction conditions and doping concentration, and the obtained photocatalytic self-cleaning environment-friendly paint has a photocatalytic function and an excellent self-cleaning performance, and is heatproof and environment-friendly.

Description

technical field [0001] The invention relates to the field of preparation of building exterior wall coatings, in particular to a photocatalytic self-cleaning environmental protection coating and a preparation method thereof. Background technique [0002] A large number of leftover materials and dust residues generated during stone processing are problems that need to be solved urgently. The leftovers from production can be processed into mosaics, which can be finely carved and sold again. However, a large amount of marble powder and waste slag produced after the development of molding materials are piled up by landfill or allowed to flow into rivers and seas, etc., which will not only cause serious land compaction and water quality deterioration, but also discharge particles and dust generated during the dumping process. , will also cause serious air pollution and human respiratory hazards. How to reuse the marble powder waste slag becomes a subject to be developed. [000...
