Abstract

A reinforced gypsum plate is made of short fibres, gypsum powder, wollastonite, calcium lime powder, calcium silicate, silicate and powdered straw and stalk. Its advantages are simple preparing process, low cost, high adhesion, hardness, strength and antiwear nature, and water-proof performance.

Description

Novel enhanced plasterboard and preparation method

The present invention relates to construction material and building and ornament materials, is main materials for wall (being building and ornament materials) and the preparation method who forms the plasterboard combination that mix with terra alba by fiber yarn particularly.

As everyone knows, materials for wall be main in the material of construction also be the material of consumption maximum, its quantity accounts for 1/2nd of material of construction, the output value accounts for 1/3rd of the building materials industry gross output value, and slight internal partition wall output accounts for materials for wall 1/3rd, the market requirement is big, occupies critical role in building materials industry.The described enhancing plasterboard of this patent promptly is that lightweight inner partition wall a kind of also comprises a kind of of building and ornament materials.

At present the whole nation is leading with market, Jinzhou, Hebei, produces Thistle board, to national most of market sales such as Shandong, Hebei, Shanxi, Shaanxi, Ningxia, Sichuan, Inner Mongols, and rising tendency year by year, demand can not be estimated greatly.By the present conventional algorithm of China, be each city each mouthful people, want one square metre of floor area of building of net value every year, and one square metre of floor area of building needs 2.5 square metres materials for wall.The i.e. city of one 500,000 population, annual demand is built 500,000 square metres various houses, needs 1,250,000 square metres of construction walls.Account for 400,000 square metres and wherein contain Thistle board at interior partition plate.The above city of China's 500,000 populations is numerous, thereby this plasterboard has a extensive future, and market is huge.In addition, compared with developed countries, the novel wall material proportion of China's light energy-saving still seldom, only account for 1%, and the U.S. accounts for 41.9%, Japan accounts for 64%, Germany accounts for 49%, and Poland accounts for 46.9%, and novel wall material growth momentum at home is swift and violent, and in the materials for wall of plate class, especially this patent novel gypsum plate series product have its many advantages again, compare than former technology Thistle board, multiple material mixing supply is abundant, enhancing property is good, surface abrasion resistance, and production technique is simple, simple installation, do not need keel, product can bore, and is waterproof, waterproof, operation labor intensity is low in the construction, and speed is fast, has extremely strong competitive power.

The objective of the invention is at paper and not enough more than the plasterboard, provide a kind of enhancing plasterboard, a kind of fibrous plaster, a kind of straw plasterboard, its light weight, high-strength, fire-retardant, sound insulation is good, easy for installation, consistency of performance, be convenient to transportation, product meets DBJ01-29-96 (Beijing's standard) JG/T3029-1995 (building trade standard), JG/T829-1998 (building trade standard).Product of the present invention is mainly used in non-bearing, the dividing wall of its party wall body, branch main wall, lavatory, kitchen wall and large bay, and furred ceilings etc. are because light weight more is specially adapted to Highrise buildings.

Combination ingredient of the present invention comprises that mainly containing effective constituent is, terra alba 65～75%, starch 1～3%, wollastonite 3～5%, calcium lime powder 2～3%, lime carbonate 5～10%, silicate 5～10%, short-fibre silk 3～5%, flax silk 2～3%, straw powder 3～15% etc.

Novel gypsum plate of the present invention is the amylan with aforesaid combination agent (or additive) and different content, under room temperature or convention condition, equivalent loading (or inequality is directly mixed) stirs and gets final product novel enhanced plasterboard series product and composition (or additive) thereof, principle is feasible, component is reasonable, preparation is simple, with low cost, easy to use, at similar Thistle board relatively, bonding strength increases substantially, hardness, intensity, fastness and wear resistance are good, and have the water-proofing performance that Thistle board does not possess, thereby solved the defective that Thistle board and terra alba thereof always exist more satisfactorily, proof is present Thistle board economic benefit and obvious social benefit on inspection, is suitable for and popularizes and apply.

Below with implementing just more to elaborate the present invention.Example one:

Composition: terra alba 65%, starch 3%, wollastonite 2%, calcium lime powder 2%, lime carbonate 2%, silicate 5%, short-fibre silk 3%, flax silk 1.5%, straw powder 5%, water 12%, at room temperature, the aforesaid combination agent mixes.Example two:

Composition: terra alba 70%, starch 3%, calcium lime powder 3%, silicate 60%, short-fibre silk 3.5%, straw powder 7%, water 7%, at room temperature, the aforesaid combination agent mixes.Example three;

Composition: terra alba 75%, starch 2.5%, calcium lime powder 3%, silicate 5%, short-fibre silk 3.8%, straw powder 2%, water 8%, at room temperature, the aforesaid combination agent mixes.

Claims

1, a kind of novel enhanced terra alba composition (or additive) is characterized in that containing in the terra alba short-fibre silk for mainly effectively becoming to send out, contain short-fibre silk 3～5%, unslaked lime 2～3%, lime carbonate 3～5%, silicate 5～10%, flax silk 2～3%, straw powder 3～15% etc., all the other water components.

2, it is characterized in that containing short-fibre silk 3%, terra alba 65%, starch 3%, wollastonite 2% according to claim (described terra alba composition (additive)), calcium lime powder 2%, lime carbonate 2%, silicate 5%, flax silk 1.5%, straw powder 5%, all the other water components.3, composition according to claim 1 (or additive) is characterized in that terra alba: short-fibre silk=20: 1.
