Abstract
A high-density calcium silicate board is made up of cement, flyash, quartz sand, cellulose fibres, wollastonite, kaolin, alumina and mica through beating, storing, discharging, copying, shaping, pressurizing, ordinary-pressure steaming, demoulding, pressing and sand grinding, and features high compactness, high nail-holding power, high strength, good fire-proof performance and convenient machining.
Description
Technical field
The present invention relates to a kind of New Building Materials, especially a kind of high-density calcium silicate board that is used to build inside and outside body of wall.
Background technology
Existing calcium silicate board be a kind of be the material of construction that main raw material is made with siliceous material, calcareous material and fortifying fibre, its moiety mainly contains following several types:
(1) mainly by cement, flyash, fibrous, wherein the flyash ratio is big, and product water-intake rate height, nail-holding ability are poor;
(2) mainly by cement, quartz sand, fibrous, wherein the quartz sand ratio is big, and product hardness height, embrittlement are difficult for later stage polishing and cutting.
(3) mainly by cement, slaked lime, quartz sand, fibrous, wherein replace cement with a large amount of slaked limes, panel density is low, intensity and nail-holding ability is poor, the water-intake rate height.
Above-mentioned several calcium silicate board all has weak point as the wallboard of the inside and outside body of wall of building.
Summary of the invention
In order to overcome the deficiency of existing calcium silicate board, the invention provides a kind of high-density calcium silicate board, have high-compactness, high nail-holding ability, and intensity increases, fire resistance is good, following process is convenient.
A kind of high-density calcium silicate board provided by the invention, its component and content are: cement 25-60%, flyash 10-50%, quartz sand 10-40%, cellulosic fibre 6-14%, wollastonite 2-8%, kaolin 2-10%, alumina 1-8%, mica 0.5-4%, all percentage ratio are weight percentage.
Making method of the present invention is: with above-mentioned materials through making beating, storage slurry, blowing, copy get, moulding, pressurization, normal pressure are steam-cured, the demoulding, pressure are steamed, sand milling is made finished product, wherein key is: the grating of improving storeroom on the one hand by interpolation kaolin and alumina fine particle, the density of product is improved, water resistance strengthens; Density and the intensity that further improves product by pressurizeing after moulding on the other hand also helps improving the nail-holding ability of product.
The invention has the beneficial effects as follows: density height, nail-holding ability height, intensity increase, fire resistance is good, following process is convenient, is suitable for building the wallboard of inside and outside body of wall.
Embodiment
The invention will be further described below in conjunction with embodiment.
The prescription of embodiment 1. each component is: 60 kilograms of cement (common 32.5#), 80 kilograms in flyash, 40 kilograms of quartz sands (250 order), 30 kilograms of cellulosic fibres (wood pulp), 10 kilograms of wollastonites (fibrous), 10 kilograms of kaolin (320 order), 8 kilograms in alumina (250 order), 2 kilograms on mica (100 order);
The prescription of embodiment 2. each components is cement (common 32.5#) 120 kg, 59 kilograms in flyash, 70 kilograms of quartz sands (250 order), 29 kilograms of cellulosic fibres (wood pulp), 10 kilograms of wollastonites (fibrous), 20 kilograms of kaolin (320 order), 10 kilograms in alumina (250 order), 2 kilograms on mica (100 order);
The prescription of embodiment 3. each components is 285 kilograms of cement (common 32.5#), 52 kilograms in flyash, 70 kilograms of quartz sands (250 order), 30 kilograms of cellulosic fibres (wood pulp), 10 kilograms of wollastonites (fibrous), 15 kilograms of kaolin (320 order), 10 kilograms in alumina (250 order), 3 kilograms on mica (100 order).
In above-mentioned 3 embodiment, respectively add an amount of water, carry out production operation by following processing parameter then:
Fiber is buckled degree of separating: 20-80%, and beating consistency: 13-16%,
Pulp storage tank concentration: 11-14%, net cage concentration: 6-8%,
Backwater concentration: 2-2.8%, negative pressure of vacuum: 0.01-0.04Mpa
Bed of material moisture: 60-68% before the vacuum, bed of material moisture: 48-58% after the vacuum,
Copy base moisture: 32-37%, moulding pressure: 24-40Mpa,
Ordinary pressure curing: 75 ℃, 8 hours.
Press and steam: 4 hours (1) heating-up times; (2) thermostat temperature pressure: 177 ℃, 0.9Mpa;
(3) constant temperature time 20-25 hour; (4) temperature fall time: 3 hours.
It is big to make density height, nail-holding ability height, intensity, and fire resistance is good, and following process is calcium silicate board easily, and the wallboard that is used to build inside and outside body of wall can satisfy service requirements.
