Description

A lightweight composite thermal insulation wallboard

technical field

The utility model relates to a thermal insulation wallboard, in particular to a lightweight composite thermal insulation wallboard.

Background technique

With the development of industry and the improvement of people's living standards, people's demand for energy continues to increase. At present, my country has become the second largest energy consumer after the United States, and the situation of energy conservation and emission reduction is very severe. In my country, building energy consumption accounts for more than 27% of the total energy consumption, and it is still increasing at a rate of 1% per year. According to statistics from the Ministry of Housing and Urban-Rural Development, the construction area of newly built houses in urban and rural areas in my country is nearly 2 billion square meters each year, of which more than 80% are high-energy buildings; the existing buildings are nearly 40 billion square meters, and more than 95% are high-energy buildings. The proportion of building energy consumption in the country's total energy consumption will rise rapidly from the current 27.6% to more than 33%. my country's new buildings have been basically designed according to energy-saving standards, the proportion is as high as 95.7%, while the proportion of energy-saving design standards in the construction stage is only 53.8%.

Building walls are one of the key points of building energy-saving design, and their material performance and structure are directly related to the quality of indoor thermal environment and the level of building energy efficiency. In residential buildings, the heat transfer through the envelope structure accounts for 72-77% of the building's energy consumption, and the heat loss through air infiltration accounts for 23-28% of the building's energy consumption. It can be seen that improving the thermal insulation performance of building walls is the key to reducing the total energy consumption of buildings. Traditional measures to improve the thermal insulation performance of building exterior walls include external thermal insulation systems and internal thermal insulation systems. The former uses foamed thermal insulation boards that are processed and pasted or glued and fastened to the external wall, or foamed particles are mixed with mortar and embedded in a batch. The thickness is on the outer wall surface, which is wrapped on the outside of the building wall with a material with good heat insulation performance; the latter is adhered or fastened to the inside of the building wall with a material with good heat insulation performance. Although the above two methods can usually meet the requirements of building thermal insulation and energy saving, there are disadvantages such as long construction period, high cost, difficult quality control, troublesome maintenance and replacement, etc., and the fire resistance and durability of the wall are often difficult to meet the requirements.

Lightweight composite thermal insulation wall panels not only have the advantages of light weight, good thermal insulation and sound insulation effects, but also can easily realize factory mechanized production, thereby shortening the construction period and speeding up the construction speed. Existing lightweight thermal insulation wallboards mostly use gypsum board or glass fiber reinforced cement composite board as the inner and outer panels, and a steel wire mesh frame is set between the two panels to connect, and polystyrene particles, mineral wool and other thermal insulation materials are filled in the cavity . This structural form is complex in structure, difficult in production process, high in cost, low in strength of the wallboard, and unsatisfactory in fireproof performance and durability of the wallboard.
