Description

Novel heat-preserving energy-saving inside and outside wall board

Technical field:

The utility model belongs to building material technical field, especially relates to a kind of novel heat-preserving energy-saving inside and outside wall board.

Background technology:

The materials for wall innovation is the important content of protecting land resources, energy conservation, comprehensive utilization of resources, improving environment; increase and rapid economy development along with China's population; the pressure of resource and environment is increasing; therefore must fundamentally change the situation of a large amount of land occupations of traditional materials for wall, consumes energy, contaminated environment; develop and apply novel wall material energetically, form the new industry that adapts with sustainable development.At present, though there is the part inventor also to invent some novel materials for walls, sandwich wall board and various combined wall board as straw utilization mostly exist intensity not high, and heat insulating ability is not strong, problems such as utilization of resources difference.

Summary of the invention:

The purpose of this utility model is, a kind of high-strength light, thermal insulation, easy for installation, novel heat-preserving energy-saving inside and outside wall board that can utilize resources synthetically are provided.

To achieve these goals, the technical solution of the utility model is, comprise shell and sandwich, sandwich is the heat preservation and soundproof layer, shell is an inorganic material layer, and inorganic material layer contains light burnt powder magnesia, magnesium chloride, light aggregate, glass fiber and modifier, inorganic material layer be coated on the heat preservation and soundproof layer around, have the double buckle of convex and the mother-son groove of spill on the upper and lower installed surface of shell respectively, light aggregate contains sawdust, stalk and flyash.

The beneficial effects of the utility model are that owing to adopted inside and outside shell structure design, sandwich is the heat preservation and soundproof layer, in light weight, heat-insulating property is superior, and shell is the inorganic material layer of scientific formulation, makes resource obtain comprehensive utilization, the intensity height, easily paste, shock resistance, anti-aging, the scope of application is wide, and is quick and easy for installation.

Description of drawings:

Fig. 1 is the structural representation of the utility model novel heat-preserving energy-saving inside and outside wall board;

Fig. 2 is the structural representation of the another kind of embodiment of the utility model.

The specific embodiment:

From the structural representation of the utility model novel heat-preserving energy-saving inside and outside wall board shown in Figure 1 as can be seen, the utility model is made up of sandwich 2 and shell 1, sandwich 2 is the heat preservation and soundproof layer, shell 1 is an inorganic material layer, inorganic material layer be coated on the heat preservation and soundproof layer around, the double buckle 3 that on installed surface on the shell 1, has convex, the mother-son groove 4 that has spill on the following installed surface, the double buckle and the mother-son groove of two blocks of whenever adjacent wallboards match during installation.Fig. 1 can be used as inner wall panel, has one deck heat preservation and soundproof layer.Heat preservation and soundproof layer as sandwich 2 can be made up of polystyrene foam plate, that polystyrene foam plate has is heat insulation, sound insulation, characteristic such as shockproof, water-fast, acidproof, alkaline-resisting, 150～180 ℃ of melt temperatures, 300 ℃ of heat decomposition temperatures, can be dissolved in aromatic hydrocarbon, chlorohydrocarbon and ketone (removing acetone) and ester class, anti-many mineral matters, organic acid, alkali, salt, lower alcohol and the aqueous solution thereof require density＞15kg/ cubic meter.The heat preservation and soundproof layer can also be made by the nano vacuum blowing agent, and the nano vacuum blowing agent has advantages such as fire prevention, nontoxic, tasteless, "dead" element.Inorganic material layer as shell 1 comprises light burnt powder magnesia 40%, magnesium chloride 30%, sawdust and stalk 20%, flyash 20% and various modifier.Light burnt powder MgO claims caustic magnesia again, the white cubic crystal, proportion 3.58 (25 ℃), 2800 ℃ of fusing points, 3600 ℃ of boiling points, be dissolved in acid and ammonium salt, be insoluble in water and ethanol, can from air, absorb moisture and carbon dioxide gradually, has activity, can be fixed with the water effect, require to contain MgO＞more than 85%, fineness 200 orders.Magnesium chloride Mg Cl26H2O, the deliquescent monoclinic crystal of white, bitter saline taste is arranged, proportion 1.56,118 ℃ of fusing points, water-soluble and ethanol, heating then loses the crystallization water simultaneously and hydrogen chloride forms magnesia, and anhydride is colourless hex crystal, proportion 2.325 (25 ℃), 712 ℃ of fusing points, 1412 ℃ of requirements of boiling point contain MgCl2＞45% fineness＞200 orders.Behind light burnt powder and the magnesium chloride mix, the initial setting time is short, and sclerosis back intensity height all has strong compatibility with mineral fibers or string.Sawdust, stalk and flyash can reduce overall weight greatly as light aggregate, turn waste into wealth.Glass fiber is as reinforcing material, and intensity is very high, and good heat resistance, corrosion resistance, thermal insulation, sound absorption properties and electrical insulating property are arranged, and requires length 1.5～2.0mm.The utility model adds micro-modifier, the fixation fire retardant of adding 4/1000ths or 8/1000ths dioxygen phosphoric acid water or millesimal silicate glasses water or millesimal ferromagnesium sulfate in order to strengthen the performance of product in the inorganic material layer of shell 1.Present embodiment can be used as inner wall panel and uses, and product specification has KPB3000 * 600 * 900mm, KPB2800 * 600 * 900mm, KPB3000 * specifications such as 600 * 1200mm.

Fig. 2 is the structural representation of the another kind of embodiment of the utility model, can be used as side fascia and uses, and two heat preservation and soundproof layers are arranged, and product specification has KPB3000 * 600 * 1500mm, KPB1800 * 600 * 900mm, KPB1800 * specifications such as 600 * 1200mm.

The utility model raw material resources is abundant, turns bane into boon, and is cheap.Because adopt bulk part combined type to install, rapid and convenient can reduce wet trade, has reduced labour intensity, has accelerated construction speed.Because lightweight, the 150mm side fascia only is 1/16 of brick mix structure 49 wall weight, can alleviate the building structure longitudinal load significantly again, reduce the building deadweight, help changing the structure design of fertile beam, fat post, deep foundation, can save steel, cement, reduce construction costs.Because wallboard is thin, under identical building area situation, can increase the usable floor area about 22%.Owing to use polystyrene foam plate, make the heat-insulating property of product and superior as sandwich thermal insulated material.

Fig. 1 and Fig. 2 are two kinds of specific embodiment of the present utility model, can also adopt other embodiment, and other concrete mode that all those skilled in the art expect without creative work is all within the utility model protection domain.
