Abstract

This invention relates to dry powder mortar characterizing that it's good in operational performance, good in construction and compatible with plaster stones, which takes cement and quartz sand as the main materials and adds white lime, hemihydrate, heavy CaCO3 to improve the compatibility with gypsum base and uses ethane-vinyl ecetate copolymer powder latex, alkyl-propyl fibrin aether, polypropylene fiber to increase binding strength and integrity of mortar and prevent cracking.

Description

石膏墙体抹灰用干粉砂浆 Plaster walls with plaster dry mortar

技术领域 FIELD

本发明涉及一种抹灰用干粉砂浆,属于一种建筑材料。 The present invention relates to a dry powder for plastering mortar, it is a building material.

技术背景目前,石膏建材作为一种新型的建筑材料,以其良好的隔热、防火、轻质、调节空气湿度、绿色安全环保等基本特性在现代建筑工程中的应用越来越广泛。 Background Currently, gypsum building materials as a new type of building material, its good insulation, fire, light, adjust the application of the basic characteristics of the air humidity, safety and environmental protection in modern green building projects more widely. 在实际应用过程中会有很多需要在石膏建筑材料上进一步抹灰装饰的情况,多年以来,人们根据传统的操作经验,在石膏建材上应用的抹灰材料仍是水泥砂浆。 In practical application process will be a lot further if necessary plaster decorative plaster in the building materials, over the years, people under the traditional operating experience, plastering materials applied in the gypsum building materials is still cement mortar. 但是,石膏制品的吸水率极高,可达到自身重量的50%,用普通水泥砂浆抹灰,由于石膏吸水的原因,不但施工时难以操作,而且由于水泥砂浆凝固后的强度太高,而石膏制品的强度较低,两者很难粘结成一个牢固的整体。 However, high water absorption of gypsum products, up to 50% of its own weight, with Portland cement mortar plastering, due to the water absorption of gypsum, is not only difficult to handle during construction, and because strength after solidification of high cement mortar, gypsum and lower strength articles, both difficult to integrally bonded into a solid. 同时由于水泥砂浆抹灰层与石膏制品膨胀系数相差太大,建筑工程会在投入使用后一年左右(即一个冻融循环周期)就会出现严重的龟裂、空鼓、甚至抹灰层大面积的脱落。 And because the plaster layer of cement mortar and gypsum products that much difference coefficient of expansion, construction will be put into use after about a year (ie, a freeze-thaw cycle) will be a serious crack, hollowing, even large plaster layer off area.

发明内容 SUMMARY

本发明的目的正是为了解决上述现有的技术不足而提供的一种在石膏建筑材料上抹灰的复合专用干粉砂浆。 An end in the present invention is to solve the above-described deficiencies of the prior art and provide a gypsum plaster building material in the composite special dry mortar.

本发明的目的是通过下列重量百分比的原料配制而成的干粉砂浆:石英砂(0.05-0.5mm) 50-56%普通硅酸盐水泥 20-28%熟石灰 8-12%重质碳酸钙 4-6% Object of the present invention are the following percentages by weight of the dry mortar fresh ingredients: quartz sand (0.05-0.5mm) 50-56% Portland cement 20-28% 8-12% by weight hydrated lime calcium carbonate 4- 6%

半水石膏 4-6%乙烯-醋酸乙烯酯共聚粉末乳胶 1.4-2.0%羟丙基甲基纤维素醚 0.2-0.4%聚丙烯纤维(3-5mm) 0.8-1.2%按上述比例将各种原材料防入犁刀式无重力混合机充分搅拌,混合均匀而制成一种专用于石膏建筑材料的抹灰砂浆。 Hemihydrate gypsum 4-6% ethylene - vinyl acetate copolymer emulsion powder 1.4-2.0% 0.2-0.4% hydroxypropyl methyl cellulose ethers of polypropylene fibers (3-5mm) 0.8-1.2% proportion the various raw materials described above preventing the coulter formula weightlessness mixer sufficiently stirred and mixed to prepare a specific gypsum building materials plastering mortar.

把按上述比例配制好的砂浆与清水按照大约4∶1.3的比例混合搅拌均匀即可用于在石膏建筑材料上抹灰。 The proportion of the above-described mixing the prepared mortar with water according to a ratio of about 4:1.3 stirred evenly for gypsum plaster in the building material. 厚度一般在3-5mm为宜。 The thickness is generally preferably 3-5mm. 按上述比例配制好的这种石膏墙抹灰砂浆具有保水性好、粘结强度高、薄层抹灰、与石膏建材有很好的相容性。 Formulated in such a good proportion of the above-described plaster wall plastering mortar having good water retention, high bond strength, a thin layer of plaster, gypsum building materials with good compatibility. 施工时易于操作、降低劳动强度,抹灰层表面可按常规做防水、粘贴瓷砖等。 Ease of construction operation, reduce labor intensity, the surface layer may be a conventional plaster waterproof paste tiles. 解决了在石膏建筑材料上面抹灰的难题,将会有效地促进石膏建材在建筑工程中的应用。 Gypsum building materials to solve the above problems plastering, will effectively promote the application of gypsum building materials in construction engineering.
