Abstract
The invention belongs to building material technical field, specially a kind of high strength gypsum partition plate and preparation method thereof.The high strength gypsum partition plate includes the raw material of following parts by weight: half 600-900 parts of water type land plaster, 2-5 parts of gypsum reinforcing agent, 0.2-0.6 parts of calcium sulphate retarder, 100-400 parts of flyash, 400-700 parts of ardealite, 200-500 parts of ceramsite sand, 8-30 parts of lignocellulosic, 6-30 parts of re-dispersible glue powder, bentonite, 10-50 parts, 600-630 parts of tap water.With land plaster (half water type) for major gelled material, the plate being prepared has the characteristics that "dead", free of contamination the present invention；Shock resistance is good, since incorporation gypsum is distributed in panel structure as reinforcing agent, then by wood-fibred, makes the shock resistance of plate, cracking resistance is improved；Due to being mixed with re-dispersible glue powder in wallboard, wall can be improved and pull surface strength and preferable waterproof effect.
Description
Technical field
The invention belongs to building material technical field, specially a kind of high strength gypsum partition plate and preparation method thereof.
Background technique
Using building gypsum as raw material, essence adds water and stirs gypsum partition board, the light-weight building plastering of moulding by casting.Production
In allow that fiber, perlite, cement, river sand, flyash, clinker etc. is added.The drying shrinkage value of gypsum partition board is only
0.24mm/m (and the drying shrinkage value of cement class walling is generally 0.8 or so), meanwhile, novel gypsum wallboard stitching portion is using now
For composite material shrinkage-compensating mounting technique, solves the problems, such as wallboard installation after-contraction cracking.Novel gypsum wallboard (GEB) is led
Hot coefficient is small, about the 20% of Cement Concrete product thermal coefficient, and the 25% of clay brick, there is good heat insulating effect, outside
Wall wallboard reaches the standard requirements of 65 ﹪ of national energy-saving, is ideal building energy conservation walling, also has fire prevention, safety and comfortable
The characteristics of, it is deep to be liked by the majority of consumers.
But gypsum partition board employed in construction market wall product at present, intensity is still lower, waterproof effect
Difference, so needing to develop, a kind of intensity is high, and water-proof function is good, has energy conservation, the gypsum partition board through matter and environmental protection characteristic.
Summary of the invention
The purpose of the present invention is against the above technical problems, provide a kind of high strength gypsum partition plate.The plasterboard ingredient comes
Source is extensive, and price is relatively low, and the product surface enhanced strength which prepares, water retention property is good, and shock resistance mentions
It rises, crack resistance is good.
Another goal of the invention of the invention is to provide the preparation method of high strength gypsum partition plate described above.
In order to realize the above goal of the invention, the specific technical proposal of the invention is:
A kind of high strength gypsum partition plate comprising the raw material of following parts by weight:
Preferably, high strength gypsum partition plate includes the raw material of following parts by weight:
The preparation method of high strength gypsum partition plate described above, comprising the following steps: weigh each raw material in proportion, then will
The half water type land plaster that weighs, gypsum reinforcing agent, calcium sulphate retarder, flyash, ardealite, ceramsite sand, lignocellulosic,
Re-dispersible glue powder and bentonite successively put into forced mixer and are stirred uniformly, after then tap water is added again into
Row stirring, wet stirring is expected, then carries out extruding or roller-compaction, last obtained by drying.
Preferably, the time stirred every time is 5-6 minutes.
Gypsum reinforcing agent can use soda ash；Calcium sulphate retarder can use sodium gluconate；Employed in the application
The preferred 2-4mm of ceramsite sand, and all raw materials are commercial product.
The positive effect of the present invention is embodied in:
(1), with land plaster (half water type) for major gelled material, the plate being prepared has "dead", pollution-free
The characteristics of.
(2), shock resistance is good, is distributed in panel structure due to mixing gypsum reinforcing agent, then by wood-fibred, makes plate
The shock resistance of material, cracking resistance are improved.
(3), due to being mixed with re-dispersible glue powder in wallboard, wall can be improved and pull surface strength, and preferably waterproof effect
Fruit.
