Description
Technical field
The invention belongs to building masonry wall heat insulating material technical field, is a kind of heat preserving facing integrated inorganic section bar and preparation method thereof.
Background technology
Along with the further standard of civilian construction energy-saving design " standard " and the enforcement of State Council's " energy-conservation regulations of civilian construction ", New Building Materials and wall thermal insulating system are had higher requirement, requirement should have good heat-insulating property, and outstanding resistance to compression, tension, ageing resistace are arranged again; Reliable barrier propterty should be arranged, and fundamentally stifled exhausted disaster hidden-trouble has permanent characteristic of water proof anti-seepage, application life again; Should environmental protection, nontoxic, elegance attractive in appearance again, decorative environment; Should avoid traditional exterior wall heat-preserving system complex procedures, can't monitor, the unwarranted difficult problem of quality, again operation simple and direct, be convenient to the construction, quality is guaranteed.Existing wall insulating layer uses polyphenyl plate, extruded sheet, glue powder polyphenyl particle, thermal insulation mortar material more, and take that insulating and facing overcoat combine composite structured, its construction operation method is normally outside the bearing wall layer, utilize the sticking insulation layer that applies of cementing agent, gauze wire cloth or grid cloth, reinforcing nail and heat-insulation and heat-preservation material, after treating that it condenses, do enhancement Layer, crack-resistant layer, protected decoration material such as bonding again ceramic tile or applying coatings at last at its external surface again.There are the defective of following several respects in this heat preserving mode and job practices:
1) bearing wall layer, insulating and facing overcoat are poor in conjunction with fastness each other, and the ceramic tile on top layer only has single decoration functions, it is bigger to conduct oneself with dignity, thereby strengthened the overall weight of body of wall, and ftracture easily, come off, cause maintenance difficult, insulation layer can not get effective protection, application life is short, and potential safety hazard is many, and coating ornamental surface fade easily, wrinkling etc.
2) the sticking deposited working procedure of insulation layer and finish coat is loaded down with trivial details, it is bothersome to take a lot of work, long in time limit, and quality guarantees by the manual work quality fully, belong to concealed work in addition, coarse to operation in the work progress, even use inferior materials and turn out substandard goods and be not easy check to find, cause construction quality out of control, influence the quality and the application life of heat-insulation system.
3) heat insulation, the waterproof of finish coat, self-cleaning property are poor, become easily infected by dust, spot, particularly highrise building, and cleaning is difficulty very, and construction is absolutely unsafe, and the aesthetic of influence building is faded on the surface easily.
4) body of wall furring material, construction integrated cost cost height, long construction period, and bring the negative effect of all many-sides such as comprehensive benefit and ambient influnence thus.
Up to now, though relevant department is paying great effort aspect constructional materials and the construction technology, and constantly develops various new heat insulating materials and technology, general effect is all not ideal.
Summary of the invention
