Abstract
The invention discloses a fiberglass reinforced hollow gypsum wallboard. The fiberglass reinforced hollow gypsum wallboard includes gypsum layers, wherein the gypsum layers from bottom to top include a first gypsum layer (1) and a second gypsum layer (1'); a plurality of cavities (2) are arranged between the first gypsum layer (1) and the second gypsum layer (1'); fiberglass (3) is embedded in each gypsum layer. By arranging cavities between the gypsum layers and embedding multiple layers of fiberglass in the cavities, the fiberglass reinforced hollow gypsum wallboard provided by the invention has the advantages that the weight of the wallboard is reduced; the compressive strength and bending strength of the wallboard are enhanced; the fireproof performance of the wallboard is improved. Furthermore, the wallboard has a simple structure, is convenient for construction, reduces costs, and is highly safe.
Description
Technical field
The present invention relates to building material manufacture field, particularly a kind of glass fiber reinforced gypsum hollow wall panel.
Background technology
Now current gypsum gathers materials and has the advantages such as light weight, insulation, heat insulation, fire prevention, sound insulation, damping, has been widely used in the field such as energy-saving wall material, mine filling material.But, light gypsum gather materials still have that fragility is large, the shortcoming such as resistance to compression and rupture strength is low, micro-expansibility, in transport or secondary processing process, easily there is crackle, brittle failure, and then have influence on following process and product quality in the light gypsum hollow wall panel that especially Area comparison is large.
Summary of the invention
The technical problem to be solved in the present invention there is provided a kind of not only lightweight but also the glass fiber reinforced gypsum hollow wall panel of pressure-proof and snap-resistent.
Technical scheme of the present invention is as follows:
A kind of glass fiber reinforced gypsum hollow wall panel, comprise gypsic horizon, described gypsic horizon comprises the first gypsic horizon and the second gypsic horizon from the bottom up, between described second gypsic horizon and the first gypsic horizon, be provided with multiple cavity, in each described gypsic horizon, be embedded with glass fiber.Adopt above structure, the weight that cavity can alleviate wallboard is set in the plaster of paris, in gypsum, add glass fiber can make wallboard coefficient of elasticity high, flexible good, not fragile in transport and process, simultaneously, because glass fiber is inorfil, there is noninflammability, and chemical resistance is good, substantially increases safety in utilization.
In order to improve the elongation of wallboard in elastic limit, and guarantee to bear high strength stretching, absorb a large amount of impact force, as preferably, be embedded with glass fiber in the middle and upper part of described first gypsic horizon, be also all embedded with glass fiber on described second gypsic horizon top and the correspondence position of pressing close to multiple described cavity inner wall.
According to the concrete condition used and the effect of load intensity, as preferably, the shape of cross section of described cavity is rectangle.
In order to reach the most dense stacking states, reaching cost-saving, improving the target of gypsic horizon combination property, as preferably, the rate that tails over of described gypsum is less than 3%, and bulk density is 800-1200kg/m
3.
In order to improve hot strength, ensureing the stability of wallboard, and having good workability, as preferably, described glass fiber is the alkali-free glass fibre rubbing shape.
Beneficial effect: the present invention arranges cavity and embeds compound glass silk and not only alleviates wallboard weight in gypsic horizon, also improves the compressive strength of wallboard, rupture strength, and improves the fire savety of wallboard, structure is simple, easy construction, cost-saving, safety is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 be in Fig. 1 A to glass filament construction schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, the present invention is made up of gypsic horizon etc., and the rate that tails over that described gypsic horizon comprises the first gypsic horizon 1 and the second gypsic horizon 1 ', two described gypsic horizons from the bottom up is all less than 3%, and bulk density is 800-1200kg/m
2.
Between described second gypsic horizon 1 ' and the first gypsic horizon 1, be provided with multiple cavity 2, the shape of cross section of described cavity 2 is rectangle; Be embedded with glass fiber 3 in the middle and upper part of described first gypsic horizon 1, be also all embedded with glass fiber 3 on described second gypsic horizon 1 ' top and the correspondence position of pressing close to multiple described cavity 3 inwall, described glass fiber 3 is the alkali-free glass fibre rubbing shape.
Manufacturing theory of the present invention is as follows:
As depicted in figs. 1 and 2, the flat steel workbench scribbling epoxy resin is gently spread lubrication oil, steel limit is risen, the first gypsic horizon 1 poured into a mould by material machine (sign), on material machine, glass fiber 3 twists disconnected by glass fiber cutter, and on the first gypsic horizon 1, lay one deck glass fiber 3 along with material machine moves, then with net formula roller, this one deck glass fiber 3 roll extrusion is entered in the first gypsic horizon 1.
Then, the rectangle mold cavity chamber core required by one group is put again in the upper surface of the first gypsic horizon 1, materials vehicle is mobile in the opposite direction afterwards also pours gypsum for the second time, now gypsum parcel covers rectangle mold cavity chamber core and forms the second gypsic horizon 1 ', second layer glass fiber 3 is re-layed at the upper surface of the second gypsic horizon 1 ', with net formula roller, this one deck glass fiber 3 roll extrusion is entered in the second gypsic horizon 1 ', and inject with serration type slotting tool in the gap of adjacent rectangle die cavity chamber core, and the glass fiber 3 of correspondence position is pressed in gap.
Then, material machine third time lays glass fiber 3, with net formula roller rolling press several times by this one deck glass fiber 3 again roll extrusion enter in the second gypsic horizon 1 ', with standard scraper plate, the second gypsic horizon 1 ' surface level is scraped several times when the second gypsic horizon 1 ' initial set, make the upper surface of the second gypsic horizon 1 ' smooth.
Last after the first gypsic horizon 1 and the second gypsic horizon 1 ' setting and harden, rectangle mold cavity chamber core is extracted out from wallboard and can form cavity 2.
It is consistent with prior art that the present invention does not describe part, and therefore not to repeat here.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing manual of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
