A prefabricated composite wallboard based on mortar external thermal insulation treatment and its manufacturing method

Abstract

The invention relates to an assembled type composite wall board based on heat insulating treatment outside mortar and a manufacturing method of the assembled type composite wall board. The assembled type composite wall board comprises a composite wall board, polymer bonding mortar, heat insulating mortar, polymer crack-resistant mortar and alkali-proof glass grid cloth, wherein the polymer bonding mortar is coated on one surface of the composite wall board; the heat insulating mortar is sprayed or poured on the polymer bonding mortar; the polymer crack-resistant mortar is sprayed or poured on the heat insulating mortar; the alkali-proof glass grid cloth is pressed into the polymer crack-resistant mortar. According to the composite wall board disclosed by the invention, a novel ecological concrete material is used, so that the problem of high consumption of conventional raw materials can be effectively solved, and the composite wall board has the advantages of being energy-saving, environment-friendly, green, ecological and the like; factory fabricated production is adopted, so that the industrialization of building components is facilitated, on-site construction assembly is facilitated, the construction efficiency is greatly improved, and the construction time is shortened. The composite wall board has the advantages of being low in cost, good in quality stability, strong in structural completeness, and quick to construct, can also well meet the energy-saving requirement of regions where the temperature is high in summer and is low in winter in China.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an assembled composite wallboard based on mortar external heat preservation treatment. Background technique [0002] In the context of the continuous advancement of my country's new urbanization process, the proportion of building energy consumption in the total energy consumption of society has been rising, which has seriously restricted economic development. Construction is more economical, energy-saving, environmentally friendly, and sustainable. The development of residential buildings is an important and effective measure to improve the level of urbanization in our country, so building energy conservation is urgent, and exterior wall energy conservation plays a dominant role in the energy consumption of the entire building. The energy-saving and structural integration of prefabricated concrete conforms to the social requirements of resource conservation and e...

Problems solved by technology

At present, the development of traditional external wall insulation faces many problems. On the one hand, the load-bearing wall and thermal insulation system are not fully integrated. The traditional external wall thermal insulation system is fixed on the main structure of the external wall by sticking or mechanically. The force of the system is complicated. The construction process is relatively complicated, requiring secondary construction, the cost is high, and the project quality is difficult to control

On the other hand, organic materials such as expanded polystyrene (EPS) or extruded polystyrene (XPS) are mainly used as external thermal insulation materials for residential buildings in my country. These materials generally have high prices, are flammable, and are easy to age , poor durability and other issues, and once burned, it will release toxic gases, endangering human health and causing environmental pollution

At the same time, the material used for the wall is traditional concrete material, which makes our country's energy and raw material consumption too large. Therefore, finding new ecological concrete wall materials has become an urgent problem to be solved now.

Finally, the structural integrity of the traditional prefabricated shear wall is poor, and the connection method needs to be further improved
