CN2073000U - Compound plaster fire board for building - Google Patents

Abstract

The utility model relates to a compound plaster fire-proof board for buildings, which uses a glass fibre mat as a surface layer and uses a plaster board which contains fillers as a middle layer. An adhesive layer is arranged between the plaster board and the glass fibre mat. The thickness of the plaster board layer is 9 to 18 mm, and the thickness of the glass fibre mat layer is 0.2 to 0.5 mm. The fillers in the plaster board is vermiculite or (and) glass fibre. The utility model has the characteristics of fire resistance, acoustic insulation, light weight, strong adaptability, etc., of a thistle board, but also has incombustibility. The fire resistance rating is A grade of the Germany DIN4102 standard, and the utility model can be used as a building element with a special fire resistance requirement.

Description

Compound plaster fire board for building

The utility model relates to the composite gypsum PLASTIC LAMINATED of using in a kind of construction work, and it can be used as the inner partition plate and the ceiling board of multilayer or high-rise building, has superior fireproof performance.

Thistle board is a kind of building construction body of wall that China grew up in nearly ten years, have light weight, heat insulation, sound insulation, characteristic such as fire-resistant, be widely used as the internal partition wall and the ceiling material of building, but its fire resistance can only reach the B level of West Germany DIN4102 standard, in actual applications, some construction site to construction material not fire class requirement high, be badly in need of solving the higher member of fire resistance rating.

The utility model is for satisfying above-mentioned those special building positions to the requirement development and design of building unit fire resistance rating, and purpose provides the composite gypsum PLASTIC LAMINATED that a kind of fire resistance rating reaches West Germany DIN4102 standard A level.

Structure of the present utility model is seen accompanying drawing 1, the surface course of making by glass fibre mat 1,5, the gypsum plank 3 that contains filler, be glue-line 2,4 between gypsum plank and the glass mat, the thickness of gypsum plank is 9～18mm, the glass fibre mat layer thickness is 0.2～0.5mm, and the cementing agent between gypsum flaggy and the mat layer is a modified starch adhesive.

Advantage of the present utility model and effect:

1. this product is in plastering, and fire resistance rating is the highest, reaches the A level of West Germany DIN4102 standard, can be used as the building unit backplate, has enlarged the range of application of former Thistle board.

2. in Thistle board is produced, need a large amount of mask paper, this paper is most of to rely on external import, though domestic have a manufacturer production, quality does not pass a test, also supply falls short of demand, after adopting the utility model technology, can not only save a large amount of foreign exchanges without mask paper, cost of production also can reduce, primary Calculation, in the cost of every square metre of Thistle board, the foreign paper cost is 3.40 yuan, the native paper cost is 3.30 yuan, and changing the utility model into, every square metre of product needs with 2.94 yuan of glass fibre mat costs, can save 0.45～0.55 yuan, annual 3000000 m that produce ²Production line, can save 135～1,650,000 yuan, and this kind product has good fire-resistance property, be used in privileged sites, price can suitably improve, and can be enterprise's profit of making profits more.

Embodiment of the present utility model is as follows:

1. main raw material(s)

Glass fibre mat

Gesso: semi-hydrated gypsum phase 〉=65%

Cementing agent: modified starch

Filler in the gypsum plank: vermiculite, glass fiber

2. technical recipe:

With the plaster of paris is 100 listed as parts by weight:

The plaster of paris 100

Modified starch 0.6～0.8

Glass fiber 0.2～0.35

Vermiculite 5～8

Glass fibre mat 2.04m ²/ m ²Plate

Water paste ratio (calculating %) 73～74 with total siccative

3. technological parameter

Slip rises heavy 1360～1420 grams per liters

3.5～4 minutes time of setting

180 °～190 ℃ of drying air temperatures

4. method of operating

Moulding on the Paper-faced gyp panel moulding apparatus at first with glass mat traction overmolding roller, is pressed in below the carry-over pinch rolls, the gypsum slurry that mixes is flow on lower floor's glass mat, converge at format roll place and upper strata mat, gypsum slurry is coated by mat, through the format roll roll extrusion, again through leveling, sclerosis, cutting, drying, operations such as stacking can be produced finished product.
