Environment-friendly and energy-saving water-proof wall material for assembly-type building and production method for wall material

Abstract

The invention relates to the field of wall materials for construction such as industrial plants, civil housing, hotels and schools, in particular to an environment-friendly and energy-saving and water-proof wall material for an assembly-type building and a production method for the wall material. The wall material comprises the followings: 900-1400 parts of light concrete, 1.75-2.1 parts of an adhesive, 5.52-6.07 parts of energy-saving materials, 60-90 parts of rebar materials, 25-30 parts of pre-buried pieces, and 2.2-3.3 parts of composite pieces. A decorative material comprises the followings: 4.2-5.2 parts of inner wall putty, 5.2-7.0 parts of outer wall putty, and 10.5-14 parts of waterproof latex paint. A lightweight coarse particle material is the particle made of one or more of waste polyphenyl foam, polyurethane foam and waste phenolic resin foam, the particle size is 5-15 mm, and the stacking density is 10 kg/m3. The wall material has the advantages of being low in water absorption rate, poisonless, harmless, energy-saving, heat-insulation and long in service life.

Description

technical field [0001] 本发明涉及工业厂房、民用住宅、宾馆、学校等建筑用墙体材料领域,尤其涉及一种装配式建筑用环保节能防水型墙材及其生产方法。 Background technique [0002] 现有钢结构建筑及钢筋混凝土建筑用墙材产品普遍存在以下缺陷: [0003] 1)节能环保性能较差,尤其复合式墙材的“冷(热)桥”未能解决,在北方尤为明显冬季可以看到由于冷桥的缘故室内挂霜,当室内温度略高时挂霜处结成冷凝水;而在南方由于热桥的缘故制冷时能量损耗大,多年来一直没有解决。 [0004] 2)目前市场上现有的复合式墙材,因外叶钢筋混凝土与夹芯节能材料间两种材料的密度及理化性能不同,产生界面间微小的间隙,正是由于界面间隙的产生,在北方冬季产生冷凝水,随之而来的产生冻涨,反复冻涨导致外叶混凝土遭到损害,严重影响建筑使用寿命。 [0005] 3)近两三年由国外引进和购买的复合式墙材用于复合的FRP连接件,该材料属于利用某种树脂制成的玻璃钢材料,其耐老化及耐久性较差,对于建筑物的耐久性影响较大。 [0006] 4)我国在近十年间各地纷纷出现了普通混凝土复合式预制墙材,该板面密度大,以某省城几家企业生产的复合式墙材为例因面密度大,制作、运输及吊装难度较大,无法满足装配式钢结构建筑及装配式混凝土建筑的需求,同时也因生产成本、运输及安装成本过高,市场无法接受。 Contents of the invention [0007] 为克服上述现有技术的不足,本发明提供了一种装配式建筑用环保节能防水型墙材及其生产方法。本发明具有吸水率低、无毒无害、保温节能、使用寿命高的优点。 [0008] In order to achieve the above object, the present invention adopts the following technical solutions to realize: [0009] 一种装配式建筑用环保节能防水型墙材,该墙材的原料组成及质量份数如下: [0010] [0011] [0012] 装饰材料:内墙腻子4.2~5.2份,外墙腻子5.2~7.0份,防水乳胶漆10.5~14份; [0013] 所述轻质混凝土为泡沫颗粒混...

AI Technical Summary

Problems solved by technology

[0003] 1) The energy saving and environmental protection performance is poor, especially the "cold (hot) bridge" of composite wall materials has not been solved, especially in the north. In winter, indoor frost can be seen due to the cold bridge. When the indoor temperature is slightly higher, frost hangs Condensed water is formed; in the south, due to the thermal bridge, the energy loss during cooling is large, and it has not been solved for many years.

[0004] 2) In the existing composite wall materials currently on the market, due to the difference in density and physical and chemical properties of the two materials between the outer leaf reinforced concrete and the sandwich energy-saving material, there is a small gap between the interfaces. It is precisely because of the interface gap that in Condensation water is generated in winter in the north, followed by freezing and swelling. Repeated freezing and swelling cause damage to the outer leaf concrete, which seriously affects the service life of the building

[0005] 3) In the past two or three years, the composite wall material imported and purchased from abroad is used for composite FRP connectors. This material is a glass fiber reinforced plastic material made of a certain resin, and its aging resistance and durability are poor. Great impact on durability

[0006] 4) Ordinary concrete composite prefabricated wall materials have appeared in various places in my country in the past ten years. The surface density of the board is high. Take the composite wall materials produced by several enterprises in a provincial city as an example. It is difficult and cannot meet the needs of prefabricated steel structure buildings and prefabricated concrete buildings. At the same time, due to high production costs, transportation and installation costs, the market cannot accept it
