Embodiment Construction
[0009] Obtain 100KG of the mixture of the following components according to the mass percentage, and stir evenly: cement 31.5%, ash calcium powder 6.5%
[0010] , heavy calcium powder 60%, hydroxypropyl methylcellulose 4.5‰, latex powder 12.53‰, wood fiber 2.3‰, starch ether 0.4‰.
[0011] According to the water-cement ratio of 0.35, it is evenly mixed. After entrusted inspection, all the test indicators meet the standard requirements of JG / T 157-2009 "Putty for Building Exterior Walls". According to the internal measurement of the enterprise, the construction efficiency can be increased by 10%-15%, and the paint can be saved by 5%.

The invention provides a formula of glossy putty powder for exterior wall decoration. With the adoption of the formula, structural compactness can be effectively improved, bonding strength and constructability are improved, and while construction quality is improved, construction efficiency can be substantially improved and economic benefit of construction is increased. The formula is characterized in that the glossy putty powder is prepared from components in percentage by mass as follows: 30%-35% of cement, 5%-8% of ash calcium powder, 60%-65% of ground calcium carbonate powder, 4 permillage-5 permillage of hydroxypropyl methyl cellulose, 10 permillage-15 permillage of latex powder, 2 permillage-2.5 permillage of wood fiber and 0.3 permillage-0.6 permillage of starch ether.
Description
technical field [0001] The invention belongs to the field of coatings for wall decoration and decoration, and in particular relates to a formula of smooth putty powder for exterior walls. Background technique [0002] The smooth putty is used as an exterior wall putty, which is used to fill the fine holes on the surface and provide a smooth and delicate surface. The smooth putty is suitable for the base layer whose flatness has reached the standard requirements. Before coating and scraping, the base should be thoroughly cleaned with sandpaper. Generally, it is constructed by scraping to prevent moisture, and it is better to scrape and coat twice. The putty should be scraped as little as possible and fully scraped, and it is not suitable for construction below 0°C. [0003] In the field of building exterior decoration, the requirements for the smooth surface of the exterior wall are generally not high, and the attention is not enough. But for some high-end buildings, especi...
