Description

一种高强度耐水粉刷石膏及其生产方法技术领域本发明涉及一种高强耐水石膏基复合抹面材料及其生产方法,具体地说,是涉及一种用于建筑物内墙、外墙及房顶板表面抹面的高强耐水粉刷石膏及其生产方法背景技术粉刷石膏具有与基材粘结牢固,凝结硬化快,凝结硬化时不收縮,施工方便, 工作效率高等特点,可以避免传统的水泥砂浆抹面层出现开裂、空鼓、脱落缺点,特别适用于加气混凝土墙面和剪力墙墙面的抹面。 A high-strength plaster and water Technical Field The present invention relates to a high-strength water-resistant gypsum plaster based composite material and method for producing, in particular, it relates to a building interior, for external walls and roof panels plaster surface of the high-strength water-resistant gypsum stucco and plaster production bACKGROUND firmly bonded to the substrate having, fast setting and hardening, setting and hardening without shrinkage, easy construction, high work efficiency, avoid the traditional cement mortar layer surface cracking, hollowing, shedding drawback, especially for plastering aerated concrete shear walls and wall. 在国外,粉刷石膏的使用已经相当普遍,如德国,70%以上的抹灰材料是粉刷石膏,英国粉刷石膏是石膏总量的50%。 In other countries, the use of plaster has been quite common, such as Germany, more than 70% of the material is plaster wall plaster, wall plaster Britain 50% of the total cast. 我国粉刷石膏的研究开发始于上世纪80年代初,现已形成四大类、十个品种,这四大类十个品种粉刷石膏是从石膏粉料相组成分类的,即半水相粉刷石膏、n型硬石膏粉刷石膏、混合相型粉刷石膏(半水石膏与硬石膏ns混合粉刷石膏,前期强度由半水石膏水化获得,而后期强度由硬石膏ns 水化获得,使粉刷石膏上墙后,具有连续的水化过程和强度增长过程),以及石膏、石灰混合型粉刷石膏。 Began research and development on our wall plaster the early 1980s, has now formed four major categories, dozens of varieties, these four categories of dozens of varieties from plaster wall plaster powder phase classification, that is half the water phase plaster , n-type anhydrite plaster mixed phase type plaster (hemihydrate plaster and anhydrite mixed ns, the intensity obtained from a pre-hydrated gypsum hemihydrate, anhydrite and late strength obtained by the hydration ns, so that the wall plaster after the wall having a continuous process and the strength increasing hydration process), and gypsum, lime plaster mixed. 在前三类粉刷石膏中,又可分成面层、底层和保温粉刷石膏,而石膏、石灰混合型粉刷石膏只适用于面层,构成了十个品种的粉刷石膏。 Three in the front wall plaster, can be divided into the surface layer, insulation layer and plaster, and plaster, lime plaster mixed applies only to the surface layer, it constitutes dozens of varieties of plaster. 在上述十种粉刷石膏中,粉刷石膏水化硬化后,其基本结构是二水石膏, 而二水石膏强度低、耐水性能差(软化系数低),而且需煅烧,生产成本高。 In the above ten kinds of plaster, the plaster after hydration and hardening, which is the basic structure of gypsum, gypsum dihydrate low strength, poor water resistance (low softening coefficient), and the need to calcination, high production costs. 我国国土辽阔,东西、南北气候差异很大,西北地区少雨,空气干燥,南方地区多雨,空气潮湿,特别是梅雨季节,空气相对湿度在80%以上,并且不管北方和南方,其厨房和卫生间总是处于潮湿空气状态,传统粉刷石膏不宜在这些环境中使用。 Our country is a vast, great stuff, the North-South differences in climate, Northwest drier, air-dried, southern rainy, humid air, especially in the rainy season, the air relative humidity is above 80%, and regardless of the North and the South, its kitchen and bathroom total moist air is in a state, the traditional plaster should not be used in these environments. 因此,需要提高粉刷石膏的耐水性能。 Therefore, the need to improve the water resistance of wall plaster. 再者,我国目前每年的工业副产品磷石膏有2000万吨,并以每年15%的速度增长;每年产生的脱硫石膏有400万吨,2010年后每年还将新增脱硫石膏2000 万吨以上;而且,还有大量的氟石膏、柠檬石膏、硼石膏、钛石膏、盐石膏等(其中氟石膏为无水石膏,无水石膏也称为硬石膏,脱硫石膏、磷石膏、柠檬石膏、硼石膏、钛石膏和盐石膏等均为二水石膏),这些工业副产品石膏又称化学石膏,仅有少量用于水泥添加剂,多数处于堆放状态,不仅占用大量土地, 而且污染环境和地下水资源。 Moreover, China's current annual industrial by-product phosphogypsum 2,000 tons, and a rate of 15% a year; gypsum produced annually by 400 million tons per year will be added in 2010 after more than 20 million tons of gypsum; Further, there are a lot of fluorine gypsum, gypsum lemon, boron gypsum, titanium gypsum, gypsum and other salts (wherein fluorgypsum anhydrous gypsum, anhydrite also known as anhydrite, gypsum, phosphogypsum, lemon gypsum, gypsum boron , titanium gypsum and gypsum and other salts are gypsum), these industrial by-product gypsum plaster, also known as chemical, only a small amount of additives used in cement, piling up the majority in the state, not only occupy a lot of land, but also pollute the environment and groundwater resources. 本发明的目的在于克服现有粉刷石膏存在的一些缺陷,提供一种高强耐水粉刷石膏,并可利用脱硫石膏、磷石膏、氟石膏、柠檬石膏等无需煅烧的化学石膏作原材料进行制备,既可降低粉刷石膏的生产成本,又有利于节能减排, 保护环境。 Object of the present invention to overcome some of the drawbacks of the prior plaster, there is provided a high-strength plaster water, and without the use of chemical gypsum calcined gypsum, phosphogypsum, fluorgypsum, lemon and the like as raw materials for the preparation of gypsum, both reduce the production cost of plaster, but also conducive to energy conservation, environmental protection. 本发明的目的是通过以下技术方案实现的:本发明之高强耐水粉刷石膏由下列材料与重量配比组成:石膏基复合胶凝材料10%〜99% (优选40%〜70%),骨料0〜90% (优选30%〜69%),添加剂0. 08〜 4%,吸附剂0〜16. 1%;所述石膏基复合胶凝材料由下列组分材料组成:混合石膏粉40%〜80% (优选50%〜70%),活性掺合料10%〜45% (优选15%〜35%),碱性激发剂4%〜15% (优发明内容选6%〜12%),可再分散胶粉0. 1%〜2%,促凝剂0%〜6% (优选1%〜3%),石灰0〜 5%,早强剂0〜1%,减水剂0〜1%,纤维0〜1.0%;所述混合石膏粉为选自二水石膏粉、硬石膏粉中的一种或它们的混合物;所述二水石膏粉可为天然二水石膏粉、脱硫石膏粉、预处理的磷石膏粉或预处理的柠檬石膏粉;优选配方,二水石膏:硬石膏=30%〜90%: 10%〜70%;必要时可加入0〜15%的半水石膏(P-CaS(v| H20或a -CaS04*| H20);粉末粒度60目〜500目(优选8 Object of the present invention is achieved by the following technical solution: The present invention water-resistant high-strength plaster from the following materials and the composition ratio by weight: 10% ~99% gypsum-based composite cementitious material (preferably 40% ~ 70%), aggregate 0~90% (preferably 30% ~69%), 4% additive 08~ 0.5, 1% adsorbent 0~16;
