Description
Technical field
The present invention relates to a kind of sheet material, mainly can be used as the various structural lumbers except that bearing wall.
Background technology
Existing structural lumber except that bearing wall has a variety of forms, for example as the gypsum plank of decorative panel, as cement composite board of inner wall panel and partition board or the like, these sheet materials have its advantage separately, all in certain field, used effectively, but having a total shortcoming, is exactly that consumption of natural resources is many.Therefore, based on environmental friendliness and resource-effective consideration, should satisfy under the condition of instructions for use, realize the recycling of waste material as much as possible, reduce the consumption of natural resource, therefore be necessary to continually develop new technology, substitute natural resource to adopt waste material.
On the other hand, at present because China's industry and the urbanization speed of development are very fast, the output of multiple trade waste such as building waste is very big, conventional land-fill method is owing to need take a large amount of land resources, therefore more and more be restricted, finding new outlets how for these trade wastes also becomes serious problems that influence sustainable development.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of stone material type and strengthen light type composite panel, this sheet material consumption of natural resources is few, and can be with multiple trade waste as its primary raw material.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of stone material type is strengthened light type composite panel, comprise central layer and two side plates that lay respectively at described central layer both sides, described each side plate all is bonded to one with described central layer, wherein a side plate adopts single layer structure at the most, at least one side plate adopts sandwich construction, the side plate of described employing single layer structure is provided with a tack coat, the side plate of described employing sandwich construction comprises a plurality of tack coats, be provided with enhancement Layer between the adjacent described tack coat, the both sides of described enhancement Layer are bonded to one with described adjacent tack coat respectively, described enhancement Layer adopts net, fabric or nonwoven, described tack coat is formed by mixed slurry curing, at least comprise in the raw material of described mixed slurry: magnesia binding material 100 mass parts, trade waste 100-900 mass parts, described magnesia binding material is made up of magnesia and magnesium salts, mol ratio between described magnesia and the described magnesium salts is 1: 0.6-1.4, described magnesium salts is a magnesium chloride, the combination of magnesium sulfate or magnesium chloride and magnesium sulfate arbitrary proportion, described trade waste adopts the powder form.
The invention has the beneficial effects as follows: owing to adopted magnesia and magnesium chloride/magnesium sulfate slurry as cementing agent, can add the powder of a large amount of trade wastes therein as filler, and improved the intensity of side plate effectively by the mode that enhancement Layer is set between tack coat, can realize the various requirement of strength that sheet material is required thus; Owing to use the trade waste powder as filler in large quantities, therefore trade waste is effectively utilized, saved natural resource in large quantities, but also reduced because of handling the required expense of these trade wastes, therefore be adapted to the various occasions that the trade waste output is many and processing cost is high, processing requirements is tight especially; Because employed trade waste powder all has certain rigidity, and wherein considerable material belongs to inorganic salts, therefore this composite board has at aspects such as hardness with the similar performance of stone material, and have the surperficial texture of stone material, therefore can be used for substituting the use occasion of stone material usually; Owing to also in the middle of side plate, be provided with central layer, can be according to actual conditions, adopt different core material, to realize the characteristic of composite plate in each side such as insulation, sound insulation, intensity, be adapted to the instructions for use of different occasions, can also to reduce the proportion of monolithic composite panel, enlarge the scope of application of this composite board thus by selecting the lighter central layer of proportion simultaneously.According to applicant's experiment, provide in the preferred embodiment in the present invention, can be not more than 820kg/m at extrudate density
3Situation under, can realize bending resistance load greater than 2800N, tensile strength is greater than 0.1MPa, compressive strength is greater than 5MPa, fire-retardant coefficient is greater than 0.98 (m
2.K)/W, and adopt at central layer under the situation of the expanded material with good soundproof effect, the sound insulation factor of the sheet material of thickness 100mm can be greater than 50dB.In addition, because side plate also has good processing properties, therefore under the situation of selecting suitable central layers such as foam cement, this composite plate can be carried out machining easily, and convenient thus the use enlarged the scope of application and mode of occupation, reduces difficulty of processing.
