Description

轻质空心墙板及其制造方法 Lightweight hollow wall and its manufacturing method

本发明涉及一种建筑构件及其制备方法,特别是一种适用于高层建筑和自由组合式房屋非承重墙体的轻质墙板及其制备方法。 The present invention relates to a building element and its preparation method, especially suitable for high-rise buildings and consisting of a non-load-bearing walls of the house combined light wall and its preparation method.

传统墙体材料大多是烧结实心粘土砖,其不仅用土、毁田、占用大量土地,而且耗煤、污染环境。 Most of the traditional solid clay brick wall material is sintered, not only with soil, Hui Tian, ​​take up a lot of land, and coal, pollute the environment. 为适应现代化高层建筑和自由组合式房屋建筑的需要,逐渐采用新型非承重墙体材料代替烧结粘土砖,以减轻建筑物自重,降低工程造价。 In order to meet the needs of modern high-rise buildings and free modular housing construction, the gradual introduction of new non-load-bearing walls brick instead of sintered material, in order to reduce the weight of buildings, reduce the project cost. 目前面世的轻质墙板,如中国专利局公报公开的90101518“硅镁加气空心轻质隔墙板”、93214229“增强泡沫水泥板”、93244814“增强水泥隔墙板”等均属此类产品,此外还有轻钢龙骨石膏板、石膏珍珠岩空心板、水泥珍珠岩空心板等,都是保护土地资源、节能产品。 Currently available light panels, such as 90101518, "attapulgite aerated lightweight hollow partition board" disclosed in Chinese Patent Publication, 93214229 "enhanced foam cement board" 93244814 "reinforced cement wall board" are such other products, in addition to light steel keel gypsum board, gypsum perlite hollow plate, hollow cement perlite board, is the protection of land resources, energy-saving products. 上述构件都有各自的优点,相比之下都存在一定的缺点和使用的局限性,仍不够理想,如普通存在板材脆性大、强度低、搬运易破损,还有的易吸潮泛卤、变形、耐水性差、应用范围受到一定局限,对金属预埋件腐蚀等问题都有待进一步改进;中国专利局以公开号1122316A公开了一种“快硬高强水泥微孔空心轻质墙板及其制备方法”,它虽然拓宽了其应用的范围,但其用作加强强度和增强耐冲击能力的无机纤维或有机纤维是加工成长为15-25mm的段并与其它原料共同搅拌的,所以容易造成搅拌不均匀,从而影响墙体的质量,导致墙体的强度并不均匀,抗冲击能力并不强,且该墙板体质较重,成本相对较高。 It said member has its own advantages, in contrast there are some disadvantages and limitations of use, is still not ideal, as the presence of an ordinary sheet brittleness, low strength, and easy handling damage, as well as the pan-hygroscopic halide, deformable, water resistance is poor, the application subject to certain limitations, for problems such as corrosion of metal embedded parts have to be further improved; in Chinese Patent Publication No. 1122316A discloses a "rapid-hardening high strength cement light wall and preparation porous method ", although it broadens the scope of its application, but its strength as a reinforcing impact resistance and enhance the ability of the inorganic fibers or organic fibers are processed into segments of 15-25mm and stirred together with other raw materials, it is easy to cause stirring nonuniform, thus affecting the quality of the wall, resulting in the strength of the wall is not uniform, impact resistance is not strong, and the physical heavy wall, relatively high cost.

本发明的目的在于克服上述现有技术的缺点而提供一种轻质空心墙板及其制备方法,该墙板体质轻、成本低、强度高、耐冲击能力强,且具有平整度好、防水、防火、隔音、保温等良好的物理性能,其制备工艺简便,生产周期短,设备利用率高,显著提高工效。 Object of the present invention is to provide a lightweight hollow wall and its preparation method overcomes the drawbacks of the prior art, the wall physical light, low cost, high strength, high impact resistance, and has good flatness, waterproof , fire protection, noise, heat and other good physical properties, its preparation process is simple, short production period, high utilization, significantly improve work efficiency.

本发明的目的是这样实现的:该墙板采用常规空心轻质墙板通用结构,所用重量百分比为如下的原料:硫铝酸盐水泥45-55%、膨胀材料10-15%、粉煤灰30-35%、建筑石膏4-7%,以及微量的玻璃纤维和占原料重40-55%的水,上述原料混制成的微泡沫料浆容量为450-560kg/m3。 Object of the present invention is achieved: the hollow wall using a conventional general light wall structure, the weight percentage of raw materials used are as follows: sulfur cement 45-55%, 10-15% expanded material, fly ash 30-35%, 4-7% gypsum building, and trace amounts of glass fiber and accounts for 40-55% of the weight of the raw material in water, a slurry capacity of the foam material is made of mixed 450-560kg / m3.

制备方法如下:按量称取上述原料,先将水泥、建筑石膏和粉煤灰拌合均匀,再加入膨胀材料进行拌合,待拌合均匀后加入水搅拌成容重为450-560kg/m3的微泡沫料浆,再把此料浆浇注到成组模具中,当辅成厚度为设计厚度的三分之一时,平整表面,然后辅上与墙板设计面积相等的玻璃纤维,再将模芯置入模具中,而后再加入微泡沫料浆到设计厚度的三分之二时,捣固后按上述方法再辅一次玻璃纤维,然后再加入微泡沫料浆至设计厚度,捣固平整,于室温下在模具中放置1-1.5小时即可抽芯,4小时脱模,自然养护即可制成墙板。 It was prepared as follows: weighed according to the amount of the raw material, the first cement, fly ash and gypsum building uniform mixing, adding expandable material mixing, mixing until uniformly stirring water was added to a density of 450-560kg / m3 of micro-foam slurry, this slurry was then cast into a mold into a group, when the secondary design to a thickness of one-third the thickness of a flat surface, then the wall of glass fibers equal area design on the secondary, then the mold when the core into a mold, and then the slurry was added to the two thirds of microfoam design thickness of the auxiliary tamping once again by the above method the glass fiber and then added to the slurry to detail the design thickness of the foam, tamping leveling, placed in a mold at room temperature for 1-1.5 hours to the core back, releasing four hours, it can be made into wallboard natural conservation.

本发明相对于现有技术有如下优点:由于本发明采用具有早强、高强、速凝、自身水化热高等优良特性的硫铝酸盐水泥为胶结材料,加入粉煤灰,再铺上玻璃纤维为增强材料,同时加入膨胀材料混配成泡沫料浆,控制料浆容量后,浇注在成组模具中,利用该水泥自身水化热,无需蒸气养护即可制成墙板,所以该墙板除具有现有各种轻质墙板的优点外,还有效克服了其受外界环境影响,易吸潮、泛卤、变形、耐水性差、生产周期长等缺点。 With respect to the prior art the present invention has the following advantages: Since the present invention has adopted early strength, high strength, quick-setting, good characteristics of higher sulfur cement hydration heat of the cement material itself, fly ash was added, and then covered with a glass fiber reinforcement material, while adding a foam expandable material mixed slurry, the control slurry capacity, cast into a mold group, itself by using the heat of hydration of cement, can be made into panels without steam curing, so that the wall in addition to having various advantages over existing plate lightweight wallboard, but also effectively overcome by its external environment, easy to absorb moisture, pan halide, deformation, poor water resistance, and long production cycle disadvantages. 由于玻璃纤维的特殊介入方式,使该墙板具有优良的强度和耐冲击能力,且墙板体质轻、成本更低。 Interventions due to the special glass fibers, so that the wall having excellent strength and impact resistance, and physical light wall, at a lower cost. 本发明的墙板特性和外观质量明显优于现有墙板,其外观平整、能钉、锯、钻、刨,减少墙体占用面积50%左右,其抽芯、脱模时间短,生产过程中无“三废”产生,不污染环境,还能变废为宝,设备利用率高,不用蒸汽养护,生产周期短,显著降低制造成本,加快资金周转,增效快,可迅速扩大应用。 Wallboard quality and appearance characteristics of the present invention is significantly better than conventional wallboard, smooth appearance, to staple, sawing, drilling, planing, reducing the wall area occupied about 50% of its core pulling short demolding time, the production process no "three wastes" generated, do not pollute the environment, but also turning waste into treasure, high capacity utilization, without steam curing, short production cycle, significantly reducing manufacturing costs, accelerate cash flow, high efficiency, can rapidly expanding applications.
