The invention relates to a light fireproof insulation board, and a method for processing the same. The light fireproofing insulation board is characterized in that: an outer wall fireproof insulation board is prepared from pearlite with the grain size of 4.1 to 4.9 mm, and the thermal coefficient of the board is 0.02 to 0.05. The invention has the advantages that: the grain sizes of the expanded perlite are screened, and the screened expanded perlite is used as raw materials for processing, so that the weight of the insulation board is reduced, the heat insulation effect is improved, and the insulation board has an obvious moistureproof effect; by fully mixing sodium methyl silicate and sodium silicate, the adhesion among perlite particles is greatly improved; meanwhile, the toughness of the insulation board is improved due to the action of a reinforcement frame, and the insulation board cannot be cracked easily and the tensile strength is improved greatly.
Description
Technical field
The present invention relates to the processing method of light fireproof thermal-insulating board, belong to building material field.
Background technology
Use at present warming plate, do not possess the fireproof function, although can preventing fires of having, but fireproof performance is relatively poor, can not satisfy actual demand, and they usually adopt cement and granules of polystyrene to mix and process, have larger weight, brittle failure easily occurs, cause and fall; And granules of polystyrene has certain impact, not environmental protection to environment.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of viscosity factor large, be difficult for occuring embrittlement, environmentally safe and resistant to elevated temperatures light fireproof thermal-insulating board and processing method thereof.Technical scheme of the present invention is: a kind of perlite exterior-wall heat insulation PLASTIC LAMINATED is characterized in that: the perlite that described exterior-wall heat insulation PLASTIC LAMINATED is 4.1～4.95mm by the grain diameter size processes, and the coefficient of thermal conductivity of this plate is 0.02～0.05.
A kind of processing method of perlite exterior-wall heat insulation PLASTIC LAMINATED is characterized in that, comprises the steps:
(1) take each raw material of following weight portion: expanded perlite 10-30 part, sodium methyl silicate 1-3 part, water glass 2-6 part;
(2) with sodium methyl silicate and the abundant mix and blend of water glass;
(3) mixed sodium methyl silicate is fully mixed with expanded perlite in cylinder with water glass, obtain mixed material;
(4) mixed material is inserted in the mould frame push, wherein, at first 1/3 of the total umber of material is inserted the mould bottom, evenly pave, then put into one deck reinforcing frame, then remaining 2/3 material is evenly paved in the mould frame, described pressure is 50-100Mpa;
(5) carry out drying after the demoulding, baking temperature is 50-300 ℃, and be 4-24 hour drying time;
(6) namely get warming plate.
A kind of processing method of perlite exterior-wall heat insulation PLASTIC LAMINATED is characterized in that, comprises the steps:
(1) take each raw material of following weight portion: expanded perlite 10-30 part, sodium methyl silicate 1-3 part, water glass 2-6 part, rock wool 10-30 part;
(2) with the abundant mix and blend of sodium methyl silicate, water glass and rock wool;
(3) mixed sodium methyl silicate, water glass and rock wool are fully mixed with expanded perlite in cylinder, obtain mixed material;
(4) mixed material is inserted in the mould frame push, wherein, at first 1/3 of the total umber of material is inserted the mould bottom, evenly pave, then put into one deck reinforcing frame, then remaining 2/3 material is evenly paved in the mould frame, carry out drying after described pressure (5) demoulding, baking temperature is 50-300 ℃, and be 4-24 hour drying time;
(6) namely get warming plate.
Advantage of the present invention is: screen by the particle diameter to expanded perlite, then process for raw material, greatly reduce the weight of warming plate, improved heat insulation effect, moisture effect is obvious, after abundant mixing by sodium methyl silicate and water glass, greatly improved the bonding force between perlite particle; Due to the effect of reinforcing frame, improve the warming plate toughness simultaneously, be difficult for embrittlement occurs, made tensile strength greatly improve.
