Description

A kind of environment protection architecture sheet material and preparation method thereof
Technical field
The invention belongs to building material field, be specifically related to a kind of lightweight, insulation, high-intensity environment protection architecture sheet material and preparation method thereof.
Background technology
Along with socioeconomic high speed development, increasing building is rised sheer from level ground, and presents the high level requirement to " building height, Form of Architecture and construction quality ".Wherein, building heat preservation is to reduce Indoor environment heat to outdoor measure of distributing, and has important effect to creating suitable indoor thermal environment and save energy, is also to construction quality important requirement and a guarantee simultaneously.
Building environmental practice is according to the difference of construction location, is mainly divided into that building external structure is carried out and carry out two kinds of modes from building interior metope.Wherein, carrying out building heat preservation from periphery construction is the mode that current building operation is generally sampled, and this mode that mainly has benefited from peripheral construction can be unified carrying out of building operation later stage.But the construction of building heat insulating exterior wall is substantially in the majority with site operation play, conventionally adopt on exterior wall, once smear bonding use mortar, paste benzene plate, linked network, thin plaster etc., because numerous and diverse cycle of this construction process is long, and interlayer bonding force is poor, the maturation period of exterior wall is differed greatly, the heat insulation function of exterior wall is declined, even affect work-ing life.Therefore, weight, resistance to compression and the resistance to cleavage of the mode of employing external wall construction to heat preservation plate material has high requirement.Especially the glass-wall building of quite being favored now, its peripheral construction heat-insulating has been subject to many restrictions especially.The mode of therefore, constructing by indoor heat insulating is more and more being used also.
But the requirement identical with outdoor heat preservation construction, also requires the heat preservation plate material of its use to have lightweight, insulation, high-intensity performance, especially fire prevention and environmental-protecting performance are had to higher requirement.
Therefore, for building heat preservation, no matter adopt which kind of form of construction work, all cut both ways, search to the bottom and must develop a kind of building board that can meet the requirement of building heat preservation workability completely, make it have lightweight, insulation, fire prevention, high-intensity performance concurrently, also can meet the requirement of environmental protection simultaneously, make it meet different construction requirements according to operating mode.
Summary of the invention
For this reason, technical problem to be solved by this invention is that building board in prior art cannot meet the problem of the performance requriements such as environmental protection, lightweight, and then provide a kind of environment protection architecture sheet material that can be used for the insulation of outdoor wall thermal insulating and indoor wall, described sheet material has the performances such as lightweight, insulation, high strength concurrently, can meet the environmental requirement of indoor construction simultaneously.
