Abstract
The invention discloses a fire-proof heat-insulation coating of buildings, and the fire-proof heat-insulation coating comprises the following main components (by weight): 40-50 parts of microporous silica; 15-20 parts of calcification cotton; 20-28 parts of calcium carbonate; 5-10 parts of gypsum; 15-25 parts of cement; 3-5 parts of PEO (polyethylene oxide); and a proper amount of water. The fire-proof heat-insulation coating has the advantages of simple preparation technology, fewer but better needed raw materials and relatively fewer required devices. The prepared product has high compressive strength, higher hardness, low tendency to fall off and age, and non-deterioration, non-toxic and tasteless and other significant characteristics, and the production cost of the fire-proof heat-insulation coating of the invention is lower than that of fire-proof heat-insulation coatings in the prior art. The fire-proof heat-insulation coating has the advantages of simple raw materials, low production cost, good applying property, environmental friendliness and uncommon fire-proof heat-insulation property, so that the fire-proof heat-insulation coating has a wide market application prospect, is one of indispensable products of interior decoration, and can be widely applicable to various exterior and outside walls of buildings, and the fire-proof heat-insulation coating product is convenient in raw material taking, has good environmental protection property, is convenient in popularization and application, and has significant social and economic benefits.
Description
Technical field
The present invention relates to a kind of novel concrete fire resistant heat preserving coating.
Background technology
Heat transmission is mainly to realize by following three kinds of approach: (1) convection current; (2) radiation; (3) molecular vibration thermal conduction.For coating, thermal convection is mainly that the air in coating completes; Thermal-radiating transmission is without any need for medium; The thermal conduction mainly solid part in coating has been assigned to.Therefore, obtain good heat insulation and preservation effect, the one, airborne convection current is attenuated to the limit; The 2nd, be by being bordering on infinite many interfaces and the modification by material makes thermal radiation drop to minimum through reflection, scattering and absorption; The 3rd, be when keeping sufficient mechanical strength, what the volume density of material will be extreme is little.
Along with socioeconomic development, the energy problem day by day highlighting is related to the every aspect of the lives of the people, the energy-conservation focus that becomes whole society's concern.In China, building energy consumption accounts for 1/3rd of national total energy consumption at present, is genuine big power consumer.Can the target that the energy consumption problem that how to reduce building trade is related to energy-saving and emission-reduction realize smoothly, is related to country's Economic Development Mode Conversion as early as possible, reduce build middle industry energy consumption by the emphasis that is our following work.
The thermal insulation coatings of selling on current China building materials market is mostly comprehensive poor, the following a series of shortcoming of ubiquity: during use, transmission of heat by convection and radiative transfer sharply raise, thermal conductivity is larger, heat insulating effect is not satisfactory, thermal insulation layer is thicker again, there is again complicated process of preparation simultaneously, material composition is various and source is inconvenient, and processing units is not enough, high expensive, and the coating of most of interior and exterior finishes does not possess environmental protection characteristic, contain many poisonous carcinogenic substance compositions, than being easier to produce secondary harm, we healthy of grievous injury.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is, provide a kind of technical process simple, operation steps is few, required equipment is few, and product dry density is light, with low cost, and fire resistant heat preserving is good, sound insulation and noise reduction, fire protection flame retarding, wear-resisting withstand voltage, insulation is resisted and is worn, acid-proof alkaline is excellent, long service life, nontoxic, extremely friendly to environment cement refractory thermal insulation coatings for building.
For solving the problems of the technologies described above, the technology used in the present invention route is: a kind of novel concrete fire resistant heat preserving coating, is become to be grouped into by following parts by weight:
The advantage of the present invention's fire resistant heat preserving coating for building is: preparation technology is simple, required starting material are fewer but better, required equipment is also fewer simultaneously, the product ultimate compression strength obtaining is high, coating is harder, difficult drop-off, be difficult for aging, never degenerate, nonpoisonous and tasteless, thermal conductivity is less than 0.05w/mk, dry density is light, heat insulation, shockproof, sound-absorbing texts is remarkable, and production cost is also low compared with the fire resistant heat preserving coating in currently available technology, exactly because the production cost of product of the present invention is low, there is again original fire resistant heat preserving characteristic simultaneously, therefore the existing wide market application foreground of product of the present invention, it is one of indispensable product of interior decoration, can also be applicable to widely various Discussion on architecture metopes uses simultaneously, and this product is existing draws materials conveniently, and there is good environmental protection characteristic, be convenient to apply, there are significant economic results in society.

Embodiment
Below in conjunction with example, the present invention is further elaborated, object is only better to understand content of the present invention.
Embodiment 1: a kind of novel concrete fire resistant heat preserving coating, is comprised of the following mainly raw material of weight part:
Its manufacturing process steps is:
(1) PEO adds 100 parts, water, soaks and makes it to become viscous solution in 6 hours, standby;
(2), by the mesoporous silica taking by formula, calcification is cotton, calcium carbonate, and add a small amount of dispersion agent, and carry out mix and blend, then add PEO solution fully to stir 30～40 minutes;
(3) add cement, gypsum to continue to stir.
Embodiment 2: a kind of novel concrete fire resistant heat preserving coating, is comprised of the following mainly raw material of weight part:
Its manufacture craft is with embodiment 1.
