Description
Technical field
The present invention relates to building material field, be specifically related to a kind of inorganic floor heating heat insulation formwork and preparation method thereof.
Background technology
Floor heating (Radiant Floor Heating) is the abbreviation of floor panel heating, be to be radiator with whole ground, by the heating agent in the flooring radiation layer, evenly heat whole ground, utilize the make progress rule of radiation of the accumulation of heat on ground self and heat to conduct from the bottom to top, reach the purpose of heating.The thermograde that low temperature ground heating agent successively decreases to head gradually at indoor formation sole, thus give the cool comfort of the warm head of pin.Ground radiation heating meets the fitness theory of the traditional Chinese medical science " temperature foot top is cool ", is the heating system of present the most comfortable, also is the symbol of modern life quality.Floor heating has developed more than 20 year in China, but realizes that really develop rapidly is after 21 century, especially in recent years.
The structure of floor heating mainly is made of floor heating heat insulation layer, floor heating pipe, floor heating backfill layer from bottom to up, and people are paving floor on backfill layer in use.Heat insulation layer for floor heating has descriptions of materials such as styrofoam, rock wool, extruded sheet in the market, the each have their own advantage of these materials, but common fatal shortcoming is: 1. this type of material is after the floor heating pipe heating, be raised to uniform temperature, a kind of poisonous organic benzene can be discharged, health of human body can be had a strong impact on; 2. this type of material is being subjected to trampling under the heavy burden situation for a long time, meeting atrophy attenuation, not only heat-insulating property is affected, also can cause heat insulation layer to separate with backfill layer, make the backfill layer hollowing, under the situation of bearing a heavy burden even fracture, the backfill layer of fracture may crush floor heating pipe under the situation of bearing a heavy burden, make the water outflow in the pipe, if maintenance, bother very much again, remove top floor, backfill layer the heat insulation layer of changing, be equivalent to the floor of warming up, ground has been done one time again, bother very much and waste; 3. after this type of material goes out of use, decompose very slowly, contaminative is very big; 4. this type of material is inflammable, and disaster hidden-trouble is big, is the material that fire department limits or forbids using in building industry.But nearly 2 years,, the problems referred to above of materials such as styrofoam, rock wool, extruded sheet have been solved with the on-the-spot pouring of foam cement floor heating heat insulation layer.All showed incomparable superiority at aspects such as energy-conservation, synergy, environmental protection, sound insulations.But all be the big machinery construction of marching into the arena with the on-the-spot pouring of foam cement floor heating heat insulation layer in the market, require the on-the-spot stirring of special technical staff, scene to lay, the curing period about 5～7 days also will be arranged, have many weak points: influenced greatly by objective condition such as technology, temperature, humidity, floor height; 2. the construction period long, task difficulty is big; 3. the know-how personnel will be arranged, supervision property is poor, and quality is difficult to guarantee; 4. be confined to large-scale building site, waste material is many; 5. and can not the quantizating index standard; Problem such as expansion, crack also appear in the later stage easily, cave in.
Summary of the invention

| Construction property | The room is polluted in the wet type floor heating, the lower floor of leaking easily, and can not construct winter. | With the benzene plate | The room is not polluted in the environment-protection dry type floor heating, and is water-tight, is not subjected to seasonal effect, four seasons raised path between farm fields construction |
| The maintenance characteristic | Floor heating pipe and backfill cement are directly built and are become one, and can't dismantle maintenance | With the benzene plate | Detachable maintenance |
| Bearing capacity | Bearing capacity is low, and ground is if any the weight point, and heating coil oppressively easily causes the floor heating pipe distortion, breaks for a long time | Bearing strength 1.2Mpa | Bearing strength can reach 6Mpa, more can not ftracture because of ballast |
| Heating-up time | Fuel factor is very slow, and the heating-up time is very long, generally needs 6～8 hours. | With the benzene plate | Fuel factor is very fast, and general 1～3 hour heating-up time is suitable with radiator. |
| Durability | After under 60 ℃ of environments for use 6 years, the benzene plate can wear out and become fragile, and can't support ground weight, the surface subsidence crack occurs | Same template | 50 years shelf-lifves, identical with building life, indeformable. |
| Slabbing | Can cause the crack when becoming the benzene plate construction of piece, and ground there is free paddy phenomenon, easily cracks | Same template | Finished product is laid, and does not produce and splits |
| Sound insulation value | Because benzene plate density is too low, surface layer is trampled and can be produced the sound in cavity | Same template | Whole soundproof effect is good, and sound absorbing power can reach 0.09～0.19% |
| Construction quality | Heat insulation layer divides several different material layer plies, can not become as a whole, is difficult for ensuring the quality of products | Same template | Heat insulation layer and packed layer all are cement products, have identical service life, and quality is guaranteed |
