Description
Technical field
The invention belongs to interior/exterior decoration technical field, is related to a kind of magnesite exterior wall fireproof decorative panel.
Background technology
China's fireproof decoration plate is from initial concrete, fireclay mortar material, to the fire protecting performance for considering to solve good material
And physical property, come out one after another using being modified various fireproof decoration plates of the special cement as base material, but many this type fire prevention
The greatest drawback of decorative panel is that generally existing returns halogen problem, i.e., one meets rainy days, and plate surface occurs as soon as moist phenomenon so that production
Product are difficult to popularization and application.In order to preferably solve the problems, such as to return halogen, start to release mineral wool fireproof decoration plate, mineral wool fire prevention dress
The burning grade of plaque also brings up to non-ignitable (A) level by fire retardant (B1) level, meets GB50222-1995《Building interior is fitted up
Design fire safety rules》Requirement.But the quality of the fire-proof board in the interior/exterior decoration in this mineral wool fireproof decoration plate
All very undesirable always, many fireproof decoration plates all more or less be present, as flameproof effect is poor, water resistance
Difference, matter is crisp, low intensity and influence its application performance；And due to complex manufacturing, the production cycle is long, cost is high and environment
Pollute the reason such as big so that interior/exterior decoration fire-proof plate is without the popularization and application that can obtain large area.And in recent years, with state
The continuous development of interior building cause, various building places are also increasingly increased to the requirement protected using fireproof decoration plate mineral wool,
Demand is also increasing.And with the popularization of new type fireproof board, magnesite fire-proof decorative panel is such as prevented fires with good performance, is light
Matter is high-strength, anti-corrosion, easily construction the features such as widely used in building materials field, but at present the universal weight of magnesite fire-proof decorative panel compared with
Weight, attached wall is not easy, the problem of intensity is not high, such as why not reduces magnesite fire-proof decorative panel fire protecting performance, and effectively improved magnesite and prevent
The Lightness and intensity of fiery decorative panel, turn into production magnesite fireproof plate decorative panel so as to improve the security of magnesite fire-proof decorative panel
Subject matter.
The content of the invention
It is an object of the invention to provide a kind of magnesite exterior wall fireproof decorative panel, resistance to elevated temperatures is good, light, and intensity is high, every
Heat, sound insulation property are good, effectively improve the security performance of magnesite exterior wall fireproof decorative panel.
In order to realize the above object the present invention proposes a kind of magnesite exterior wall fireproof decorative panel, according to percentage by weight
Raw material includes：Mineral wool 18~25%, mineral wool 15~22%, magnesium chloride 7~12%, magnesium cement 13~20%, caustic dolomite
Powder 6~12%, vermiculite power 4~8%, aluminum oxide 5~10%, nickel oxide 5~10%, silester 6~11%.
Preferably, described magnesite exterior wall fireproof decorative panel, includes according to the raw material of percentage by weight：Mineral wool 22%, glass
Glass cotton 18%, magnesium chloride 9%, magnesium cement 16%, caustic dolomite powder 9%, vermiculite power 6%, aluminum oxide 7%, nickel oxide 6%,

Further, described magnesium chloride is magnesium chloride granules and water by 3.7:1 fused magnesium chloride solution.
Further, described magnesium cement is obtained by the light burnt powder or low temperature calcination dolomite obtained by calcined magnesite stone
Ashes be cementing agent.
The technical effects of the invention are that：The present invention uses mineral wool, mineral wool as heat-barrier material, and itself is non-ignitable, plays
The effect of assisting flame-resistant, and resistance to elevated temperatures is good, light, the magnesite exterior wall fireproof decorative panel so based on mineral wool, mineral wool is light
Matter is affixed on exterior wall.The caustic dolomite powder of use, it by dolomite mineral (is calcium carbonate and magnesium carbonate double salt is main component to be
Ore) obtain after roasting.Magnesium chloride in the present invention is by 3.7 with water:The magnesium chloride solution of 1 mixing, compatibility are good.Magnesium
It with the light burnt powder obtained by calcined magnesite stone or the ashes (main component MgO) obtained by low temperature calcination dolomite is glue that cement, which is,
Agent is tied, with magnesium chloride hexahydrate (MgCL2·6H2) etc. O water-soluble magnesium salt is blender, adds water, the light-burning magnesium powder formed and
Magnesium chloride hexahydrate is as primary raw material.The hardenite main component that magnesium cement is formed is 5Mg (OH)2·MgCL2·8H2O and
3Mg(OH)2·MgCL2·8H2Magnesia-magnesium chloride that O crystalline phases are formed-water ternary compound crystalline phase double salt, in addition, also
Some Mg (OH)2Gel.It can be hardened quickly at normal temperatures and pressures, and formation fragility is bigger and hardness is very high
Artificial stone, the present invention utilize its this hardening gelling, are worked on the magnesite exterior wall fireproof decorative panel of the present invention, rise
It is heat-insulated, sound insulation property is good to gelatification, while using the mixed than enhancing magnesite exterior wall fireproof decorative panel intensity of the present invention.This
Invention is ground by pulverizer, the processes such as uniform slurry, forming and hardening, maintenance, obtained magnesite exterior wall fireproof decorative panel are mixed in heating
Fire prevention newly can be good, and intensity is high.
