Description
Technical field
The present invention relates to a kind of Grade-A fireproof self-heat-insulationwall wall body and manufacture method thereof.
Background technology
Along with carrying out of energy conservation, exterior wall external insulation technology of buildings is widely used, but while outside wall heat preservation is generally applied, fire failure also occurs again and again.Fire occur reason be many-sided, but lagging material inflammable be also a major reason.Existing warming plate fire-protection rating is generally B1, B2 level.For this reason; inorganic heat insulation material (as rock wool, glass bead, pearlstone etc.) is adopted to be invented as the building exterior-wall A-class fireproof thermal-insulating plate of filling; because the good heat insulating of rock wool, price are low; A level fireproof heated board often adopts rock cotton board to be lagging material; its structure by upper strata screed, moderate soak material layer and below screed form, be three layers of integrative-structure.The deficiencies in the prior art are, 1, due to outside fireproof heated board end face rock wool layer is directly exposed to, the easy water-absorbent of rock wool layer is high, yielding; 2, workman directly contacts rock cotton board in construction, generally causes tetter, even if protect, also cannot avoid; 3, rock cotton board insufficient strength, easily comes off.Need to be improved.In recent years, although occurred that some can substitute the A level fire-retardant heat-insulation material of rock wool, all keep away and unavoidably carry out again hanging the trouble of pasting warming plate after building body is completed, take a lot of work, bothersome, increase cost and extend the duration; And the appearance of the bodies of wall such as air-entrained concrete building block does not reach the requirement of energy-conservation 65%.
Summary of the invention
Object of the present invention is exactly to solve the problem, a kind of Grade-A fireproof self-heat-insulationwall wall body and manufacture method thereof are provided, this body of wall is once constructed, both completed building by laying bricks or stones of main body body of wall, the requirement of energy-conservation 65% can have been reached again, and do not needed to do heat preservation construction again, also there is the features such as the fire prevention of A level, water-impervious, and quality is light, intensity is large, effectively reduces the heavy burden of buildings, be beneficial to quake evaluation.
