Abstract
The present invention relates to a double-fibre reinforced gypsum board, belonging to the field of building material. Glass fibre web fabric is used as external reinforcement material, and the gypsum power mixed with the plant and mineral short fibre is used as internal reinforcement material, a small quantity of water of added, then the above-mentioned materials are mixed into semi-dried form, said semi-dried material is moulded by mechanically-extruding so as to obtain the invented gypsum board. Said invented double-fibre reinforced gypsum board not only possesses common characteristics of general gypsum board, but also it strength, toughness, nail-holding force and water-property exceed that of other gypsum board.
Description
The present invention relates to a kind of double-fibre reinforced gypsum board, belong to building material field.
Used partition wall in the present building, the dalle kind is a lot, Thistle board, double-reinforced gypsum plate, honeycomb paper gypsum plank, gypsum bubble card, paper fibrous plaster etc. are arranged, the former belongs to pouring forming technology production, back two kind semidry method compression moulding technologies, the pouring forming technology timber intensity is low, and is frangible in the carrying, construction and installation percent defective height; Compression moulding technology, although the timber intensity height, equipment investment is big, and production efficiency is low, is difficult for popularizing on a large scale, and application is restricted.
Double-fibre reinforced gypsum board and production technology thereof:
The present invention relates to a kind of double-fibre reinforced gypsum board and production technology thereof; Specifically be the gypsum plank that a kind of geminal fibers strengthens, belong to building materials field.
Adopt plastering to be a lot of of nonbearing partition, ornament materials both at home and abroad.Plant the fine composite plate etc. that strengthens as Thistle board, sandwich composite gypsum board, plasterboard, gypsum particle board, gypsum parian plate, gypsum; Wherein Thistle board is in the humidity larger area, and application is restricted.Gypsum bubble card, although the energy machinery production, sheet material thickness restraining factors are more, equipment investment is big, the cost height, though paper fibrous plaster intensity height, material has limitation based on the paper fiber.
The purpose of this invention is to provide a kind of can mechanization production continuously, be not subjected to the restriction of material condition again, adopt glass fiber mesh to strengthen outward, a kind of sheet material of plant, the interior semidry method extruding moulding box moulding process that strengthens of mineral chopped strand being produced.
Double-fibre reinforced gypsum board of the present invention can be widely used in body of wall, roof, floor and furniture, be to make the external surface reinforcing material with glass fiber mesh, in the plate core, do interior reinforcing material with corn nuclear, bagasse, various short fiber of plant, mix with cementitious material such as gypsum, add low amounts of water and mix and stir into leather hard through the moulding of extruding moulding box, curing forms on the production line.
The prescription of this gypsum partition board is: gypsum 75-85%, light material 15-25%, the water of gypsum weight 30 ± 5%.Its manufacturing process flow is a land plaster, and light material mixes according to a certain ratio, sprays into the water of gypsum weight 30 ± 5% then, mix and stir into leather hard, supply with the moulding box single lead screw ex truding briquetting machine, applied the sheet material that glass fiber net cloth is made in shop, two surfaces up and down simultaneously, the length cutting that sheet material can be on request.
Figure of description is as follows:
Fig. 1 is a double-reinforced gypsum plate section of the present invention.
Accompanying drawings embodiment is as follows:
(1) is the surface layer glass fiber mesh in the double-fibre reinforced gypsum board of the present invention (Fig. 1); (2) be the bottom glass fiber mesh; (3) be the board core material material.
The technological process of production is: earlier with building gypsum plaster 75-85%, light material (corn nuclear, bagasse, various short fiber of plant) reinforcing material was mixed by weight in 25-15% did: spray into the water that accounts for gypsum weight 30 ± 5% then, in mixing machine, mix and stir into leather hard, supply with the moulding box single lead screw ex truding briquetting machine then, glass screen cloth spreading machine structure is the end of with about the while warp, the top layer at sheet material is applied in surface layer glass fiber mesh shop, extrude compacting through moulding box, again through rolling device compacting once more, make inner short fiber, cementitious matter gypsum and appearance reticular fibre are closely linked, solidify the back by the design size cutting, drying is finished product then.
As the prescription of dual-fibre gypsum board, different according to different inserts.
1. filler is that corn nuclear (being crushed to 0-5mm) is that main prescription is: building gypsum plaster 75-85%, corn nuclear 22-12%, bamboo fibre or glass fiber (the long 5-10mm of φ＜1mm), 3%, above-mentioned three kinds of materials are mixed spill into the blending mixing device after even, spray into the water that accounts for gypsum weight 30 ± 5% then, mix and stir into leather hard, supply with the moulding box single lead screw ex truding briquetting machine then, the while warp is glass screen cloth spreading machine structure up and down, the end of with, the top layer at sheet material is applied in surface layer glass fiber mesh shop, extrude compacting through moulding box,, make inner short fiber inserts again through rolling device compacting once more, cementitious matter gypsum and appearance reticular fibre are closely linked, solidify the back by the design size cutting, drying is finished product then.
2. filler is that the prescription of sweet screening slag (string, saw do not look into etc.) is: plaster of Paris 82-85% filler 18-15%, other method for production is with 1.
Double-fibre reinforced gypsum board of the present invention, except that having the total characteristic of other gypsum plank, intensity especially, toughness, nail-holding ability, water resistance is all above other template, and panel weight is light, and the crack is not indeformable, and physical dimension is accurately stable, but the mechanization batch process.
Claims (3)
1. double-fibre reinforced gypsum board, be characterized in fiberglass gridding cloth as the external surface reinforcing material, the core filler is a reinforcing material in corn nuclear, bagasse, wood fibre and various short fiber of plant are done, mix with cementitious material such as gypsum, add low amounts of water and mix and stir into leather hard through the moulding of extruding moulding box, solidify a kind of sheet material that forms on the production line, be called for short double-fibre reinforced gypsum board.
2. it is characterized in that according to 1 said double-fibre reinforced gypsum board on the claim plate core prescription is: building gypsum plaster 75-85%, (being crushed to 0-5mm) corn nuclear 22-12%, bamboo fibre or glass fiber (the long 5-10mm of φ＜1mm), 3%, above-mentioned three kinds of materials are mixed spill into the blending mixing device after even, spray into the water that accounts for gypsum weight 30 ± 5% then, mix and stir into leather hard, supply with the moulding box single lead screw ex truding briquetting machine then, the while warp is glass screen cloth spreading machine structure up and down, the end of with, the top layer at sheet material is applied in surface layer glass fiber mesh shop, extrude compacting through moulding box,, make inner short fiber inserts again through rolling device compacting once more, a kind of sheet material that cementitious matter gypsum and appearance reticular fibre are closely linked and make, solidify the back by the design size cutting, drying is finished product then.
