Description
Technical field
The invention belongs to production of construction materials field, relate generally to a kind of inorganic core for A level fireproof metal composite plates and
Its preparation method.
Background technology
With the quickening of process of industrialization, the heavy construction in city gradually increases, but, what heavy construction was faced disappears
Anti- difficulty is also much larger compared with common building, and with the frequent generation of domestic large-sized fire accident in recent years, country builds for high level
Build propose higher and higher requirement using the fire protecting performance of material, there is many lacking in itself in the PE interlayers of traditional aluminium-plastic panel
Fall into, for example：Inflammable PE, the pole fire hazardous under the conditions of high pressure, heat release, electric discharge etc., in combustion process, flame retardant effect is not good
PE can in a large number melt drop, melt drop thing sustained combustion the intensity of a fire can be caused again constantly to expand, in burning generation a large amount of flue gases pair
Human body also toxic effect, the in addition decomposition of PE burnings can also cause the Collapse Deformation of sheet material, especially apply in airport, car
Stand, gymnasium, the decoration such as public top grade entertainment place and skyscraper when, the common aluminum plastic containing PE interlayers is subject to certain
Limit.The PE masterbatch of existing B levels fire-protection rating, simply improves its burning point, the still meeting after temperature reaches burning point
Burning, so as to initiation fire accident.Drawbacks described above causes composited aluminum and plastic decking to have serious fire risk, once there is fire
Calamity, will cause immeasurable threat to the life and property of people, so, aluminium-plastic panel cannot be expired using PE as core interlayer
The burning behavior class of sufficient national compulsory architectural fire-protection methods code requirement, people urgently find more preferable material to solve this
A little problems.
The content of the invention
It is steady that the technical problem to be solved is to provide a kind of reasonable, the obtained product quality of concise in technology
Fixed, completely unnatural, environmentally friendly inorganic core for A level fireproof metal composite plates and preparation method thereof.
The present invention is achieved through the following technical solutions：
For the inorganic core of A level fireproof metal composite plates, it is comprising component and mass fraction：42-77 parts of magnesium hydroxide, AR

The characteristics of, for frost-cracking-preventing effect when severe cold area or low skyscraper high temperature.
Based on knowledge accumulation for many years and practical experience, inventor is final to determine to take as above again through test of many times
Raw material type coordinates and corresponding proportioning, and main consideration is：First, it would be desirable to select to embody the topmost fire prevention resistance of this product
The basic material of the effect of combustion, i.e. magnesium hydroxide, magnesium hydroxide as main fire retardant, with environmental friendliness, fire-retardant, suppression cigarette and
Filling function, and decomposition temperature is high, can use under conditions of processing temperature is higher, when there is combustion case, hydrogen-oxygen
Changing magnesium can occur the decomposition reaction being dehydrated of absorbing heat, and dilute flame zone gas concentration, take away a part of combustion heat, while be dehydrated generating
Oxide the charring layer of one firm compact is formed in material surface, play a part of to stop that heat and oxygen are entered, so as to
Reduction burning velocity is reached, propagation of flame has been prevented, is reduced smokescope, and from the effect of fiery self-extinguishment；And AR glass fibres, it is
100% inorfil, is not only able to be bonded to improve service life, and bring in the erosion for being effective against high alkaloid substance at ordinary times
Power is strong, elastic modelling quantity, shock resistance, tension, bending strength is high, do not fire, freeze proof, resistance to temperature, humidity changing capability are strong, cracking resistance,
The remarkable characteristic of anti-permeability performance, the structure that especially physical modification brings strengthens ability and projects, and designability is strong, easy-formation, greatly
The big performance for improving core, it has good compatibility and powder between, can mix with other raw materials rapidly, is evenly distributed,
Uniform and irregular network distribution system is formed in powder, disperses structural stress, so as to reach the enhanced effect of cracking resistance；
Glass bead, because surface vitreous forms certain granule strength, physicochemical property is sufficiently stable, and ageing-resistant weatherability is strong, has
The anti-fiery ﹑ sound absorption qualities of excellent exhausted hot ﹑, as aglite in this product, can improve as inorganic core needed for manufacture
Slurry and easy mobility and from anti-intensity, reduce finished product shrinkage factor, improve product combination property, reduce comprehensive production cost；
Meanwhile, blast furnace iron powder is typically made steel the waste residue refinement for producing by steel mill and is formed, and has also reached twice laid, the mesh of reduces cost
's.The final employing of these raw materials and the selection of their mass fraction are all the inorganic cores according to A level fireproof metal composite plates
Performance requirement determined by lot of experiments, according to the design that principles above is carried out, the A levels fire prevention plate core that the present invention is provided
The powder of material has reached that A level flameproof effects, physical property be up to standard, environmental protection beneficial effect, and the cooperation of these ratios makes
The inorganic core of the invention is obtained while ensure that performance, manufacturing cost is minimum, if using other formulas or comparing
Example, the possible poor-performing of fireproof metal composite plate for causing product cost high or to be finally made is undesirable.
The invention also discloses the preparation method of the above-mentioned inorganic core for A level fireproof metal composite plates, comprises the steps of：
（1）Prepare raw material, in strict accordance with technological requirement raw material is purchased, incoming material must be tested strictly by quality requirement
Receive, detect do not meet quality requirement material forbid warehouse-in；
（2）Various raw materials are weighed in proportion by dispensing, must be in strict accordance with regulation during weighing；
