Description
Technical field
The present invention relates to a kind of ceiling board, particularly a kind of modification ceiling board and preparation method.
Background technology
The tradition ceiling board is to be made by certain operation by silica powder, lime, cement, asbestos, exists the shortcomings such as water-repellancy is poor, shock resistance is poor.Common ceiling board water-intake rate is up to 30% left and right, and the ceiling board folding strength after full water 50% left and right that descended.In addition, concerning ceiling board, in case suction, its thermal conductivity will sharply rise, give goods deposit, pack, transport and on-the-spot the stacking all brought very large trouble, also limited its range of application.If ceiling board is carried out modification, make it have water-repellancy and higher shock resistance, pressure-proof and snap-resistent intensity etc., can promote the use of the nonweight-bearing body of wall of building etc., prospect certainly will be wide.
Water-borne acrylic resin can coordinate with the water-based cementing matter that cement, lime, gypsum etc. are commonly used, and improves intensity, toughness and water-repellancy.

Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ceiling board of good physical performance.
For this reason, the raw material weight proportioning of ceiling board provided by the invention is: 33 parts～35 parts, diatomite, 24 parts～26 parts of carbide slags, 8 parts～10 parts of cement, 11 parts～13 parts of alkali resistant glass fibres, 8 parts～10 parts of water-borne acrylic resins, 10 parts～12 parts, water.
Cement adopts 32.5 grades of ordinary Portland cements, and the diatomite fineness is more than 200 orders, and alkali resistant glass fibre length is less than 5cm, and in carbide slag, effective calcium amount is more than 70%.
The present invention adopts water-borne acrylic resin to carry out modification to ceiling board, that water-borne acrylic resin is replaced a part of water in production process, it can be stirred fully with batching combine, then through operations such as mold pressing, steam press maintenances, make a kind of novel inorganic building material.
Modification is to be controlled by the process of the aquation of gelling material and acrylic resin film forming.In water-borne acrylic resin the segregation out water and the Ca in acrylic resin particle and ceiling board raw material
2+, solid Ca (OH)
2And chemical reaction occurs between surface of aggregate, and strengthened bonding between material, improved the mechanical property of the ceiling board after the sclerosis.Due to can be before the hydrated cementitious early stage film forming of water-borne acrylic resin, with the reaction of hydrated cementitious, moisture is fewer and feweri, just can form within a certain period of time three-dimensional reticulated structure, both additions of conserve water based acrylic resin is also in the water tolerance that to a certain degree keeps ceiling board.
In ceiling board autoclave at high temperature maintenance processes, at SiO
2-CaO-H
2In the O reaction system, during the insulation beginning, at first at the surperficial Calucium Silicate powder hydrated product CSH (I) that forms cancellated Calucium Silicate powder hydrated product CSH (II) and fiber fines shape or needle-like of diatomite.Along with the prolongation of soaking time, diatomite constantly dissolves, and makes inner hollow, and CSH (II) and CSH (I) change into the tobermorite crystal simultaneously.At last holding stage, the tobermorite crystal all changes xonotlite basically into, to reach the intensity of plate.Add water-borne acrylic resin in ceiling board making processes after, both can form one firmly whole, ceiling board is played a very good protection, thereby the mechanical property pointer such as ceiling board resistance to compression, folding strength and toughness is all increased.
The water-borne acrylic resin modification improves significantly to the performance of ceiling board, and table 1 is the performance test results of the water-borne acrylic resin modification ceiling board of different addition quantity, and compares with common ceiling board.In table, the reflection water-borne acrylic resin mixes and rear the ceiling board performance is significantly improved effect, but acquires a certain degree when volume, and the ceiling board performance variation is little, and according to test-results, the water-borne acrylic resin incorporation is selected 12 parts.
Table 1 different addition quantity water-borne acrylic resin ceiling board the performance test results
The present invention also provides the manufacture method of above-mentioned ceiling board, comprises following making step:
(1) mixing water based acrylic resin and water
Water-borne acrylic resin and 1/3 water are evenly mixed.
(2) alkali resistant glass fibre of loosening
All alkali resistant glass fibres are put into stirrer, then the 1/3 total water amount that adds is loosened.
(3) make slip
After complete 3 minutes of the alkali resistant glass fibre of loosening, drop in order carbide slag, cement, diatomite and remaining 1/3 water, then stir and made required slip in 3 minutes, pulp density is 10%～12%.
Pulp density is controlled most important to the slurry flowing process production technique, because aborning, is not adopt backwater to starching in bucket type pulp storage tank and blowing groove, and the concentration of slurrying is just the concentration of pulp flow port basically, only has the feed back beating consistency that the small portion impact is arranged.In pulping process, fiber is loosened water must be through metering, to guarantee that pulp density is in allowed band with backwater with making beating.
(4) become base
Be sent to mat forming machine and form slab through multi-stage vacuum dehydration, extruding.
(5) cut base
The slab of making is through cutting vertically and stacking after horizontal burr.
(6) high-temperature vapour maintenance
The steam-cured dolly that is placed with straight sheet pile is sent into carried out steam press maintenance in autoclave.Pressure is 0.9MPa～1MPa, and 180 ℃ of steam pressure temperature keep 10h at this pressure and temperature.
(7) oven dry
The oven dry of sheet material drying machine, water ratio is lower than 10%.
(8) plate facing sand light
The plate face carries out getting product after the single face sanding through grinder.
The present invention has that lightweight, intensity are high, waterproof, shock resistance better, the premium propertiess such as not inflammable, sound insulation good, heat insulation strong, pollution-free, easy processing, product can bore, saws, follows closely, dig, dry construction operation etc., and can large-scale industrial production.
The hydrated product that carbide slag in base material of the present invention and diatomite generate in pressing the steaming hydro-thermal reaction is mainly the tobermorite crystal, has guaranteed product strength.Water-borne acrylic resin is able to take the steam press maintenance of 180 ℃ of high temperature, has satisfied the requirement of ceiling board steam press maintenance under 180 ℃ of high temperature.
