Abstract
A reinforcing gypsum product with different composition fibers is formed in the following weight ratio: bita gypsum powder 100 portions, redispersable rubber powders: 1-3 portions bastose: 0.2-0.3, paper fiber: 2-4, neutral glass fiber; 0.3-0.5, aggregate: 4-5, water: 70-75. First of all, water and paper fiber are put into a mixing beater to be mixed for 2 minutes according to the said proportion, then, the gypsum powder, redispersable rubber powder, bastose, the glass fiber and aggregates are added into it and mixed for one minute to be poured into the die by a pouring machine. When the slury is hardened, it is dried manually to get the product.
Description
Technical field:
The invention belongs to the materials for wall of building, particularly building nonbearing partition material.
Background technology:
The body of wall product of construction market is a lot of at present, mainly contain cement class, gypsum class, calcium silicates class three major types product from the material classification, wherein in the majority, and the gypsum series products is under new form, energy-conservation, lightweight, environmental protection, reusable characteristics stable development with it with the cement series products.
Summary of the invention:
The three-dimensional gypsum board products that strengthens of the non-bearing of our development is to form with the raw material of following weight ratio: 100 parts of β land plasters; Re-dispersible glue powder 1-3 part; Lignocellulosic 0.2-0.3 part; Paper fiber 2-4 part; Medium-alkali glass fibre 0.3-0.5 part; Aggregate 4-5 part; Water 70-75 part.
1, the β land plaster is that main coagulated material is given full play to its time of setting of fast, convenient formation, lightweight, "dead", reusable characteristics.
2, lignocellulosic, paper fiber, medium-alkali glass fibre are reinforcing material.Through special process three kinds of fibers are evenly dispersed in the three dimensions of sheet material, have strengthened the shock resistance and the cracking resistance of sheet material greatly.Because composition, length, the modulus of elasticity difference of above-mentioned three kinds of fibers are so should not evenly disperse by general technology.For this reason our specialized designs dispersing technology.
Dispersing technology:
It is in 200 rev/mins the mixer that paper fiber and water are put into rotating speed, stirs 2 minutes.And then add lignocellulosic, medium-alkali glass fibre, land plaster, expanded perlite, re-dispersible glue powder etc. and stir and got final product in 1 minute.
3, re-dispersible glue powder is the gelled networks material.Improve the surface strength of sheet material, reduced the water absorption rate of sheet material.
4, expanded perlite is an aggregate.Select specific unit weight (unit weight 〉=80kg/m for use
3) expanded perlite be aggregate, reduce the surface density of sheet material effectively.
Compared following characteristics by the three-dimensional enhancing gypsum plank that above-mentioned material is made with other sheet material:
1, be that main material thereby sheet material have "dead", free of contamination characteristics with the β land plaster.And the energy consumption of land plaster production is 1/3 of a cement production consumption, so this product is the natural green product.
2, shock resistance is good, by be uneven in length, fiber distributed in three dimensions in sheet material of three kinds of unlike materials that modulus of elasticity is different, make the shock resistance of sheet material improve more than 30% than the sheet material that fiber bidimensional distributes.The cracking resistance of sheet material also is improved simultaneously.
3, lightweight, sheet material surface density are 22-25kg/m
2High-strength, sheet material compressive strength 〉=10Mpa.
4, the sheet material specification is 1200-900 * 900-600 * 25-30mm.The sheet material specification is moderate, meet construction module, is convenient to carrying and construction is used.
5, added certain water yield in process of production, a part of water can evaporate along with drying, has formed a large amount of fine gap in sheet material inside, improves the fireproof performance of sheet material.The fireproof performance of this sheet material satisfies national standard.
6, owing in sheet material, added re-dispersible glue powder, make this product solve the big problem of common gypsum goods water absorption rate preferably.
7, sheet material is taked artificial drying.Send into the Drying tunnel kiln after the sheet material sclerosis and dry drying time 24 hours, 80 ℃ of bake out temperatures.
8, this sheet material is according to the construction technology of national worker's law regulation, forms the lightweight nonbearing partition, can satisfy the functions of use such as fire prevention, sound insulation, shock resistance of internal partition wall.
Description of drawings:
Accompanying drawing is a process chart of the present invention.
The specific embodiment:
Example one:
Get 100 parts of β land plasters by weight, 2 parts of re-dispersible glue powders, 0.2 part of lignocellulosic, 0.3 part of medium-alkali glass fibre, 4 parts of expanded perlites mix above-mentioned material, again with 2 parts of paper fibers, join in the above-mentioned materials mixed after 70 parts of mixing of water, stir, get final product through cast, oven dry.
Example two: get 100 parts of β land plasters by weight, 3 parts of re-dispersible glue powders, 0.3 part of lignocellulosic, 0.5 part of medium-alkali glass fibre, 5 parts of expanded perlites.3 parts of paper fibers, 75 parts in water gets final product by above-mentioned technology making.
Claims (2)
1, a kind of three-dimensional gypsum plank that strengthens is characterized in that forming with the raw material of following weight ratio:
β land plaster: 100 parts
Re-dispersible glue powder: 1-3 part
Lignocellulosic: 0.2-0.3 part
Medium-alkali glass fibre: 0.3-0.5 part
Paper fiber: 2-4 part
Aggregate: 4-5 part
Water: 70-75 part
Get the said ratio raw material, earlier β land plaster, re-dispersible glue powder, lignocellulosic, medium-alkali glass fibre, aggregate are stirred, the mixture that adds entry and paper fiber again stirs into slip, makes through pouring into a mould, drying.
2, the three-dimensional manufacture craft that strengthens gypsum plank, it is characterized in that: it is in 200 rev/mins the mixer that paper fiber and water are put into rotating speed, stirred 2 minutes, and then add lignocellulosic, medium-alkali glass fibre, land plaster, expanded perlite, re-dispersible glue powder and stir and got final product in 1 minute.
