Description
Technical field
The present invention relates to a kind of composite plate for building, more particularly, to a kind of perlite calcium silicate board.
Background technology
Expanded perlite is that perlite ore is preheated, manufactured a kind of internal to be cellular after TRANSIENT HIGH TEMPERATURE calcining expansion
The material of the white granular of structure.Its principle is:Perlite ore is through the broken ore in sand form for forming certain particle size, preheated roasting
Burn, instant heating (more than 1000 DEG C), moisture vaporizes in ore in sand form, in vitreous ore in sand form internal expansion that contains of softening, is formed
Loose structure, the nonmetal mineral product perlites of 10-30 times of volumetric expansion are divided into according to its expansion process technology and purposes difference
Three kinds of forms:Open bore (open cell), closed pore (closed cell), hollow hole (balloon).
But expanded perlite thermal-nsulation plate due to be expanded perlite granule by adhesives into tabular, although matter
Gently, but complex manufacturing technology, the pearlite slab production technology produced both at home and abroad at present are to pass through hot pressing with artificial auxiliary material, conveying
Shaping, its shortcoming are；Labour cost is too high, yields poorly, and production cost is high, and production daily is average to produce 15 pieces per hour.And
The thickness of plate cannot be below 8mm, can not be molded if being less than 8mm, during making.
The negative oxygen ion that negative oxygen ion is described as " air vitamin " is advantageous to the physical and mental health of human body.It mainly passes through
The nervous system of people and blood circulation can have an impact to the organism physiology activity of people, and negative oxygen ion can allow the capillary of human body to expand
, promote regenerative cell's tissue so as to play a part of stimulating circulation.And cellular oxidation can be also prevented, it is exactly so-called anti-
Only aging, enhance metabolism, improve immunity.In addition also have except hiding, prevent bacterial growth, mould proof, heat accumulation and other effects.Electricity
The releasable negative oxygen ion of gas stone, but the speed of tourmaline releasing negative oxygen ion is low, concentration is low, it is impossible to meet demand.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of labour cost is low, production
Cost is low, the high perlite calcium silicate board of yield.
The purpose of the present invention can be achieved through the following technical solutions：A kind of perlite calcium silicate board, it is characterised in that
Include the raw material of volumes below percentage composition component：
Described raw material includes the component of volumes below percentage composition：
Described expanded perlite is that perlite raw material is placed in puffing furnace in 600-900 DEG C, it is expanded by 10s and
Into.
Described cellulose includes the one or more in wood fibre, paper fiber, rice fiber, bamboo fibre or mineral wool.
The thickness of described calcium silicate board is 3~30mm.Both 5-10MM thin plate can be fabricated to, can also be fabricated to 20-
30MM slab, can flexible Application.
The particle diameter of described expanded perlite is 0.5~5mm, and the particle diameter of described tourmaline is 200~6000 mesh.Expansion
The volume ratio of perlite and tourmaline is preferred：55~56：0.4~0.5.
When crushing tourmaline, powder size will control the micro situation within 200-6000 mesh, and fineness exceedes this scope
When it is excessively careful be unfavorable for manufacturing process, and not up to the scope when powder cross the perlite that conference leads to not insert after expansion
Interlayer, influence anion burst size.Expanded vermiculite granularity will be controlled between 0.5-5MM, and particle is too small, influence sheet material bear from
The function of son release, particle is too big, can reduce the intensity of sheet material.
Therefore the key that granularity this details in particular range is technique is controlled in crushing process.
Tourmaline has the function of releasing negative oxygen ion, but the amount of pure tourmaline releasing negative oxygen ion is few, speed is slow, presses
Tourmaline is mixed with expanded perlite according to ratio of the present invention, expanded perlite has cellular more hollow structures, and insulating properties is stronger,
Electric charge can be added up, form the potential difference of various ranks, " tourmaline " is a kind of special polarity crystalline solid of structure, has pyroelectricity
And piezoelectricity, in the presence of the lower and change of ambient temperature is excited by electric field, anion is can release, anion is empty
After oxygen capture in gas, negative oxygen ion is formd.Therefore, expanded perlite can improve the energy of tourmaline releasing negative oxygen ion
Power, and because perlite has higher layer charge number, therefore handed over higher cation exchange capacity and stronger cation
Adsorption capacity is changed, can lasting releasing negative oxygen ion.
A kind of preparation method of perlite calcium silicate board, it is characterised in that comprise the following steps：
(1) feeding：It is raw material to weigh expanded perlite, cellulose, quartz sand, cement, tourmaline by volumn concentration；
(2) spice：Above-mentioned raw materials are mixed by agitator, stirred；
(3) it is molded：The material to stir is injected into stock tank by high-pressure pump, belt is then being flowed into by stock tank
In；Self-forming processed is starched using belt stream slurry conveying cylinder pressure viscosity；
(4) dry：Product elder generation normal temperature after shaping conserves 4 hours, then 100 DEG C of steam pressures 18 hours, finally with 120 DEG C of bakings
Dry temperature is dried 5 hours.
Stirring described in step (2) is high-speed stirred 5-10min.
The speed of belt stream slurry conveying described in step (3) is 50m/min.
The perlite calcium silicate board technological process of production of the present invention is to pass through cold moudling, high temperature with the production of full-automatic slurry flowing process
Maintenance, dry, packaging.Can also use drags slurry processes or mucilage method to prepare pearlite slab of the present invention.Its advantage；Labour cost is low, raw
It is low to produce cost, yield is high, and average production yields 200 per hour is opened daily.
Compared with prior art, the present invention has advantages below：
The characteristics of 1.0 products are both outside the unique advantage with perlite also with calcium silicate board
1.1 fire protecting performances are good, and fire resisting rank is up to A levels；
It is 1.2 anticorrosions, anti-mildew

1.4 noise reductions, sound insulation
1.5 intensity are high, shock resistance is good
1.6 water resistances are good, and hydroscopicity is high
2.0 is capable of releasing negative ion, is splendid green product
Strictly in ratio batch mixing of the present invention, if the content of tourmaline powder can cause the release of anion when being less than this scope
Amount is not abundant enough, if the content of same expanded perlite influences whether fire prevention, anticorrosion, sound-absorbing when being less than the index, every
The effect of sound.The amount for the sheet material releasing negative oxygen ion that inventive formulation obtains is used as 3000/cm3.It is sufficiently mixed uniformly
Above composition is also critically important.Especially the present invention uses cement as binding agent, without being bonded using conventional swelling perlite powder
The adhesive needed, its main advantage are：A/ timber intensities are high；B/ not mutabilities；C/ water resistances are good；D/ is free of organic matter,
Discharged without pernicious gas, D/ is easy to construction and installation.
3.0 product thickness scopes are big, and use is wide
Product can both be fabricated to 5-10MM thin plate, can also be fabricated to 20-30MM slab, can flexible Application.
4.0 product yields are high, cost is low
5.0 product lightweights, construction and installation are convenient
Expanded perlite is added in 5.1 products, there is the advantages of lightweight
The back side of 5.2 products can screw in crab-bolt or screw, realize the mode that machinery hangs patch, construction and installation, dismounting are extremely
It is convenient.
6.0 it is widely used
Available for positions such as the lining of building, Side fascia, ceiling board, curtain wall liner plate, composite wall faceplates.
