Description
Technical field
The present invention relates to building fields, and in particular to a kind of thermal insulation material composite assistant and is used to prepare heat absorbing type magnesium-based not
Fire the application of fireproof heated board.
Background technique
In building thermal insulation material industry, mainly there is two major classes product at present；One kind is organic matter thermal insulation material, such as: poly- ammonia
Ester cystosepiment, polystyrene foam (including xps extruded sheet, polystyrene foam styrofoam, phenolic resin foamed board etc.), it is this kind of
The good heat insulating of material, thermal coefficient is in 0.028~0.042 (w/ (m.k)), but the anti-flammability of these materials, thermostabilization
Property, the strength of materials are all undesirable, and Actual combustion grade is all at B2 grades or less.In addition one kind is inorganic material or mixing material, such as:
Foamed cement rock wool board, magnesite foam board etc., this kind of material thermal conductivity is higher, generally in 0.046~0.09 (w/ (m.k)),
And water absorption rate is higher, intensity is also undesirable.
In order to enable thermal insulation material to have more dominance, successively there is true golden plate, polymerization styrofoam in nearly 2 years market.This two
Kind of material only improves a step in flame retardant property, but majority at A2 grades hereinafter, and stability, anti-flammability etc. do not mentioned
It is high.
Summary of the invention
The purpose of the present invention is to provide a kind of thermal insulation material composite assistant and it is used to prepare the non-ignitable fire prevention of heat absorbing type magnesium-based
The application of insulation board.
To achieve the above object, the invention adopts a technical scheme as:
A kind of thermal insulation material composite assistant, composite assistant component are as follows: magnesia, magnesium sulfate, gypsum, aluminium hydroxide, phase transformation
Material, mixed aid；
Composite assistant components by weight are as follows:
The composite assistant components by weight are as follows:
The phase-change material is acrylic acid；The mixed aid is water-reducing agent, waterproofing agent, reinforcing agent；Wherein water-reducing agent, anti-
Aqua, reinforcing agent are used according to arbitrary proportion mixing as mixed aid, and water-reducing agent is polycarboxylate dehydragent；Waterproofing agent is hard
Resin acid calcium；Reinforcing agent is ceramic fibre.
The composite assistant is used to prepare the non-ignitable fireproof heated board of heat absorbing type magnesium-based, using foamed polystyrene board as substrate,
Composite assistant is injected in foamed polystyrene board through vacuum infiltration equipment, the non-ignitable fireproof heated board of heat absorbing type magnesium-based is made.
The foamed polystyrene board is that EPS particle high-temperature foaming and setting forms, bulk density 18Kg/m3。
The preparation step of the non-ignitable fireproof heated board of heat absorbing type magnesium-based are as follows:
1) by weight mixed oxidization magnesium, magnesium sulfate, gypsum, aluminium hydroxide, phase-change material, mixed aid, stirring preparation
Composite assistant；
2) foamed polystyrene board is put into vacuum infiltration equipment, is injected into polystyrene through vacuum infiltration composite assistant
In foamed board；
3) by inject composite assistant after foamed polystyrene board be put into maintenance between, through conserve be made heat absorbing type magnesium-based it is non-ignitable
Fireproof heated board.
The vacuum infiltration pressure of the vacuum infiltration equipment is -3bar；Curing temperature is 30-40 DEG C between the maintenance, is supported
Protecting the time is 20~24 hours.
Reaction mechanism of the invention are as follows: the chemical reaction of special composite assistant produces when by burning to absorb organic compound combustion
Raw heat, usually releasing along with chemical bonded refractory Heshui, amount of heat, which is absorbed, to be taken away.
Advantage for present invention:
Of the invention is used to prepare the non-ignitable fireproof heated board of heat absorbing type magnesium-based using composite assistant, and thermal coefficient is in 0.042-
0.045 (w/m.k), combustion rating are A grades, have the characteristics that excellent combination property, are ideal external-wall heat-insulation materials, installation is applied
Work is easy, and cost performance is high, in addition, pollution-free in use, no discharge is met environmental requirements.
