preparation example Construction

[0071] In one embodiment, the preparation method of the titanium dioxide-coated hollow ceramic microspheres comprises the following steps:

[0072] Weigh 5g of ceramic microbeads, put in 50mL of distilled water, drop in 10 drops of alanine glutamate, stir and disperse in a 500mL four-neck flask, adjust the pH of the system to 2.0 with hydrochloric acid solution, add an appropriate amount of urea, and then heat up At 70-80°C, add 10% tin tetrachloride solution, use the OH- generated by the hydrolysis of urea to precipitate the tin salt and evenly deposit it on the surface of the ceramic microbeads, then add TiCl 4 At the same time, an appropriate amount of urea was added to the solution, reacted at 70°C for 1h, continued to heat up to 80°C for another 2h, and then aged at 70°C for 1h. Filter the microbeads, roast at 300° C. to remove crystal water, and then roast at 900° C. for 30 minutes to obtain titanium dioxide-coated ceramic microbeads in rutile phase.

Embodiment 1

[0123] This embodiment provides a thermal insulation dry powder putty and its preparation method and use method, the steps are as follows:

[0124] In terms of weight percentage, weigh 50% desulfurized gypsum, 3% redispersible latex powder, 10% titanium dioxide-coated hollow ceramic microspheres, 4% aluminum oxide powder, 6% mica powder, 26.1% heavy calcium, 0.1 % retarder, 0.5% water retaining agent, 0.3% water reducing agent.

[0125] Preparation method: Pour desulfurized gypsum, redispersible latex powder, aluminum oxide powder, mica powder, heavy calcium, retarder, water retaining agent and water reducer into mixing equipment and mix evenly, then pack to obtain component A . The titanium dioxide-coated hollow ceramic microspheres are individually packaged to obtain component B.

[0126] How to use: Weigh water, pour into component A, stir at 800rpm at high speed for 4 minutes, then let stand for 5 minutes, then add component B, stir at 200rpm at low speed for 2 minutes, ...

Embodiment 2

[0128] This embodiment provides a thermal insulation dry powder putty and its preparation method and use method, which are basically the same as in Embodiment 1, the only difference being that the amount of titanium dioxide-coated hollow ceramic microspheres and heavy calcium is different, and the steps are as follows:

[0129] In terms of weight percentage, weigh 50% desulfurized gypsum, 3% redispersible latex powder, 5% titanium dioxide-coated hollow ceramic microspheres, 4% aluminum oxide powder, 6% mica powder, 31.1% heavy calcium, 0.1 % retarder, 0.5% water retaining agent, 0.3% water reducing agent.

[0130] Preparation method: Pour desulfurized gypsum, redispersible latex powder, aluminum oxide powder, mica powder, heavy calcium, retarder, water retaining agent and water reducer into mixing equipment and mix evenly, then pack to obtain component A . The titanium dioxide-coated hollow ceramic microspheres are individually packaged to obtain component B.

Abstract

The invention relates to thermal insulation dry powder putty and its application method. The thermal insulation dry powder putty includes A component and B component; in parts by weight, the preparation raw materials of the A component include: 40-60 parts of gypsum; 4-8 parts of aluminum oxide; In total, the raw materials for the preparation of component B include: 5-15 parts of hollow ceramic microspheres coated with titanium dioxide. The thermal insulation dry powder putty can be scraped or sprayed on the wall in batches of 2mm-5mm, without increasing the construction process and without reducing the building area, it can play a role in heat insulation and reduce building energy consumption, and is suitable for hot summer and cold winter regions A residential building with compartmentalized and intermittent energy consumption.

Description

technical field [0001] The invention relates to the field of building materials, in particular to thermal insulation dry powder putty and its application method. Background technique [0002] In hot-summer and cold-winter regions in my country, summer is hot and uncomfortable, and winter is humid and cold. With the improvement of people's economic and living standards, the requirements for indoor environment comfort are getting higher and higher. Air-conditioning refrigeration and heating have become the main means of improvement in hot summer and cold winter regions, but this has brought about the problem of increased building energy consumption. At present, building energy saving is an important national strategy of our country, and the energy saving of envelope structure is one of the most effective ways of building energy saving. [0003] Residential buildings in hot-summer and cold-winter regions in my country generally adopt compartmentalized and intermittent energy c...
