Abstract
The invention discloses inorganic heat-preserving slurry, which consists of following raw materials in percentage by weight: 25-45 percent of early strength cement, 35-55 percent of closed pore perlite, 10-20 percent of inorganic fiber, 2-10 percent of rare earth and 1-5 percent of rubber powder, wherein the inorganic fiber is asbestos or glass fiber or a mixture thereof; and the particle diameter of the closed pore perlite is 1.5-2.0 millimeters. The inorganic heat-preserving slurry does not burn fundamentally, is free from fire control potential safety hazard, has a structure in a fully-bonded form, has high integrity, and is free from splicing gaps and heat bridges; an inorganic material is not aged or deformed, has the same service life as a building main body, is not required to be replaced, and is low in maintaining cost; both sides of a substrate wall body are not required to be optimized with a mortar leveling structure, so that the overall thickness of an outer wall is reduced, and the construction ratio is increased; a construction process is simple and convenient, and is suitable for special parts and various shapes; and the inorganic heat-preserving slurry has high strength after being molded, is suitable for field molding of a stressed and impacted part, and is free from cutting waste.
Description
Technical field
The present invention relates to building material field, specifically is a kind of inorganic heat preservation slurry.
Background technology
Existing inorganic heat preservation panel material mainly contains EPS, XPS warming plate, polyurethane foam warming plate, glass wool, rock cotton board and phenolic board etc.But all there are a lot of defectives in these lagging materials.1, EPS, XPS warming plate: can't reach A level fire prevention, the sticking globality of system point poor, be prone to produce heat bridge, be prone to aging, basic unit's body of wall need levelling, inapplicable and moulding position, intensity low, have the plate of sanction to waste, be inappropriate for cross-operation, belong to the organic chemistry material pollution is arranged.2, polyurethane foam: can't reach A level fire prevention, be prone to aging, sometimes the thermal insulation layer outside need levelling, inapplicable and moulding position, intensity low, be inappropriate for cross-operation, belong to the organic chemistry material pollution is arranged; 3, glass wool, rock cotton board: the sticking globality of system point is poor, be prone to produce heat bridge, sometimes basic unit's body of wall need levelling, inapplicable and moulding position, intensity low, have the waste of the plate of sanction, construction operation to stimulate human body, be prone to the moisture absorption that absorbs water; 4, phenolic board: the sticking globality of system point is poor, be prone to produce heat bridge, be prone to aging, be prone to efflorescence, basic unit's body of wall need levelling, inapplicable and moulding position, intensity low, the waste of the plate of sanction is arranged, belong to the organic chemistry material and have pollution toxic.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of inorganic heat preservation slurry of high insulating effect.
Technical scheme of the present invention is achieved in that the inorganic heat preservation slurry, and its raw material is formed and content wt% is:
Short-term strength cement: 25-45
Closed perlite: 35-55
Inorganic fibre: 10-20
Rare earth: 2-10
Rubber powder: 1-5.
The preferred group of inorganic heat preservation slurry becomes:
Short-term strength cement: 30-40
Closed perlite: 40-45
Inorganic fibre: 14-18
Rare earth: 4-6
Rubber powder: 2.5-4.
Said inorganic fibre is: asbestos or spun glass or both mixtures.
The particle diameter of said closed perlite is at 1.5-2.0mm.
Beneficial effect of the present invention is: inorganic heat preservation slurry of the present invention does not burn, and no security against fire hidden danger structure is completely sticking form, and good integrity does not have splicing slit and heat bridge; Inorganic can not produce aging distortion, with the same life-span of building body, need not change, keep in repair cheap, and basic unit body of wall both sides do not need the composition optimizes of mortar levelling layer, reduce the exterior wall integral thickness, increase percentage of usable dwelling area; Construction technology is easy, and working procedure is few, short in-place forming of duration, is applicable to privileged sites and various moulding; Intensity is high after the moulding, is applicable to stressed and the position that is hit (exterior wall, party wall, roofing, staircase, elevator raise, underground heat insulation etc.) in-place forming, does not have the cutting waste; Be applicable to cross-operation, no potential safety hazard; Main material is natural mineral matter, and is pollution-free.

Inorganic heat preservation slurry of the present invention can reach A level fire prevention, good integrity do not have heat bridge, aging, reduce that working procedure is saved material, is suitable for moulding, intensity is high is suitable for and the position that is hit, suitable and cross-operation, pollution-free.It reaches technical parameter:
Fire-protection rating: A1 level
Dry density: 240-300 KG/M3
Ultimate compression strength: 0.25-0.38 Mpa
Thermal conductivity: 0.053 W/mK
Linear shrinkage ratio: 0.15-0.18 %
Pressure is fried in shallow oil cohesive strength: 60-100 Kpa
Tensile strength: 0.11-0.13MPa
Frost resistance mass loss rate: 3-4 %
Frost resistance ultimate compression strength rate of loss: 15-19 %
Ratio of briquetting: 80%.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
