Embodiment 1

[0041] Add 20% of attapulgite powder to 20% hydrochloric acid by mass fraction, soak in hydrochloric acid, stir mechanically for 2 hours, centrifuge and wash. 30% of the ceramic waste powder is crushed, ball milled, dried, sieved and granulated to make a powder with a fineness of 350 mesh. Mix octadecyltriethylammonium chloride, magnesium chloride and water evenly, heat the mixed solution to 60°C, adjust the pH of the mixed solution to 2 with hydrochloric acid; transfer the prepared mixed solution into a stirring tank, and add green layer silicon at the same time 40% cerite powder, start the emulsifier to stir, heat to 120°C, and stir for 1 hour. Add 0.5% of silane coupling agent and 9.5% of nano-titanium dioxide powder into the mixed solution, heat the mixed solution to 160°C, and stir and evaporate for 1 hour.

Embodiment 2

[0043] Add 10% of attapulgite powder to 1% hydrochloric acid by mass fraction, soak it, stir it mechanically for 2 hours, centrifuge and wash it. 23% of the ceramic waste powder was crushed, ball milled, dried, sieved and granulated to make a powder with a fineness of 850 mesh. Mix cetyltriethylammonium bromide, calcium chloride and water evenly, heat the mixed solution to 90°C, adjust the pH of the mixed solution to 6 with hydrochloric acid; transfer the prepared mixed solution into a stirring tank, and add green Layer 60% of cerite powder, start the emulsifier to stir, heat to 150°C, and stir for 3 hours. Add 2% of titanate coupling agent and 5% of nano-titanium dioxide powder into the mixed solution, heat the mixed solution to 180°C, stir and evaporate for 0.5h.

Embodiment 3

[0045] Add 13% attapulgite powder to 15% mass fraction of acetic acid to soak, mechanically stir for 2 hours, centrifuge and wash. 20% of the ceramic waste powder is crushed, ball milled, dried, sieved and granulated to make a powder with a fineness of 500 mesh. Mix octadecyltriethylammonium chloride, calcium chloride and water evenly, heat the mixed solution to 80°C, adjust the pH of the mixed solution to 4 with hydrochloric acid; transfer the prepared mixed solution into a stirring tank, and add green Layer 55% cerite powder, start the emulsifier to stir, heat to 130°C, and stir for 2 hours. Add 2% aluminate coupling agent and 10% nano-titanium dioxide powder into the mixed solution, heat the mixed solution to 170°C, and stir and evaporate for 1 hour.

Abstract

The invention belongs to the technical field of preparation of an exterior coating, which concretely relates to a powder material for the exterior coating. The powder material comprises the following raw materials by weight percentage: 10-20% of attapulgite powder, 20-30% of ceramic waste material powder, 5-10% of nanometer titanium dioxide powder and 0.5-2% of coupling agent. The powder material has the obvious effect that 1) addition of the ceramic waste material in the raw materials provides a new approach for processing the ceramic waste material, solves the environment pollution problem of the waste ceramic, and the powder material has good economic benefit and social benefit; and 2)addition of the powder material can obviously improve the high / low temperature resistance performance and aging resistance performance of the coating.

Description

technical field [0001] The invention belongs to the technical field of exterior wall paint preparation, and in particular relates to a powder material for exterior wall paint. Background technique [0002] Due to the large specific surface area and strong interfacial interaction of nano-dispersed phases, quantum effects and surface effects are generated, so that nano-materials not only exhibit properties different from general macro-composite materials, but may also have special properties and functions that the original components do not have. It has broad prospects for preparing high-performance and multi-functional materials. [0003] Exterior wall coatings currently available on the market, such as latex paint, have problems such as short service life and poor weather resistance. Affected by climates such as high temperature in summer and low temperature in winter, the coating is prone to aging, wrinkling, cracking, and peeling. Therefore, in order to make up for the de...
