Description
Technical field
The present invention relates to a kind of wall body structure, refer in particular to a kind of body of wall intelligent heat preserving space enclosing structure.
Background technology
The energy-conservation starting of China is late, and awareness of saving energy is not strong, and the energy consumption waste is very serious, take inhabitation as example, the developed country identical with weather conditions compares, and exterior wall is substantially 4～5 times, and the roof is 2.5～5 times, exterior window is 1.5～2.2 times, and the door and window gas permeability is 3～6 times, and total power consumption is 3～4 times.
The relevant departments such as State Council, the Committee of Development and Reform, the Ministry of Construction, State Environmental Protection Administration propose to be strict with, be the Eleventh Five-Year Plan period, and building energy conservation will realize saving 1.01 hundred million tons of standard coals, reduce discharging more than 400,000,000 ton of carbon dioxide.The gross area of energy saving building will be above 21.6 hundred million square metres.
Along with the develop rapidly of national economy, people require to change the comfort type of " cool in summer and warm in winter " into from the basic model of " keeping out wind and rain " to living environment simultaneously.Be the comfort level in the holding chamber, utilize air-conditioning system that adjustment is carried out in the room, impel the temperature adjustment energy consumption of building to increase considerably.At present, the power consumption of the air-conditioning of China's building accounts for more than 68% of total energy consumption of building.In addition, along with the quickening of Development of China's Urbanization, the growth at full speed of China's overall floorage becomes another important power consumption field so that be used for the energy consumption of building.For this reason, in the Medium-and Long-Term Plan for Conserving Energy Resources that National Development and Reform Commission promulgates, building energy conservation is classified as and industrial energy saving and energy-conservation one of the three important large emphasis energy-saving field that are all of transportation.Along with the requirement of building a resource-conserving society of China's proposition and the in succession appearance of national energy-saving consumption reduction policy, the energy-saving building material certainly will will become the from now on developing direction of building material.And research high strength, low cost and high fire line, low-density foamed material are the problems that needs to be resolved hurrily.
For these reasons, on the construction market a kind of body of wall intelligent heat preserving space enclosing structure of employing is arranged at present, it generally comprises from outside to inside finishing coat, strengthens floated coat, bottom screed, foaming cement thermal insulation layer (usually adopting the EPS material), adhesive layer and body of wall substrate layer, wherein also is coated with glass strengthening grid layer of cloth in the above-mentioned enhancing floated coat.Above-mentioned body of wall intelligent heat preserving space enclosing structure mainly realizes the heat insulating effect of body of wall by described foaming cement thermal insulation layer.
So-called foam cement namely is to inflate and the light-weight foam heat insulating material of formation in cement paste, has reached the purpose that reduces cement slurry density, proposes at Aldrish and the Mitchell by the U.S. in 1975.Foam cement is applied in the construction technology of reinforcing oil well the earliest.1979, the people such as the Yamads of the U.S. first in the oil field with foam cement and obtained good effect.Along with the development of modern foam cement technology, foaming and steady bubble technology have all obtained significant progress.Bubble can be uniform and stable be dispersed in the whole foam cement slurry system, thereby make the building foamed cement material of function admirable.Compare with other cement, foamed cement material has the characteristics such as density is low, permeability is low, thermal conductivity is low, and slip is sneaked into bubble in whipping process, and forms the foam cement mixture, the rear expansion that pours into the mold, thereby can produce the foamed material product of various shapes.Along with the progress of foaming technique, foam cement not only is applied to the insulation of reinforcing oil well and well casing, but with a kind of brand-new light thermal-insulating constructional materials appear at common people in face of.
Although foam cement is as insulating, its unique superiority is arranged, not only has compressive strength high, coefficient of thermal conductivity is low, stable chemical performance, environmental protection, the advantage such as modification not, but foam cement is not batch production production, need in building-site operation construction, thereby product quality exists very big-difference, some foam cement does not reach due physical performance index at all, and mainly there is following problems in the described foam cement construction: at first be that the foam cement water supply volume is too much, cause the oeverall quality of foam cement to descend; Next is that cement consumption is excessive, and thermal and insulating performance be can not be guaranteed; The quality heterogeneity of foaming water at last, poor stability.The in addition common heat insulating material that adopts of China, all belong to organic material such as EPS, XPS, polyurethane foam board etc., although have preferably heat-insulating property, but because fire-protection rating is low, endurance quality is poor, energy consumption is high etc. problem, not only renovate cost high, and aspect safety, brought great potential safety hazard.Emphasized again in No. 65 literary composition of the Ministry of Public Security in 2011 that it is the material of A level that the civilian construction heat insulating material for external must adopt combustibility.This shows, we pay attention to that building energy conservation reduces discharging, in the dwelling environment comfort level, we also will pay attention to other combination properties such as security performance, endurance quality, environment pollution of material.
