Description

External-wall heat-insulation material and preparation method thereof
Technical field
The invention belongs to building material technical field, be specifically related to a kind of external-wall heat-insulation material and preparation method thereof.
Background technology
External thermal insulation system is constituted by heat-insulation layer, protective layer and fixing material (adhesive, anchoring piece etc.) and is suitable for General name is constructed in the non-bearing heat-preserving being arranged on exterior wall surface.External wall outer insulation can alleviate the impact of cold bridge, protects master simultaneously Body walling by great temperature degeneration stress, is not made that huge contribution in terms of building energy conservation, is current China building wall The energy-saving technological measure being most widely used in energy-saving, is also the insulation way vigorously advocated of current country.
At present, it is applied to the external thermal insulation system of China and mainly has following several form: expansion polystyrene plate (EPS) Thin-coat plaster wall outer heat preservation system, large die built-in (having net, without net) external thermal insulation system, glue powder polyphenyl granule exterior wall external thermal insulation system System, polyurethane (spraying, sheet material) external thermal insulation system, extruded sheet (XPS) external thermal insulation system etc..Wherein EPS sheet is with valency The advantages such as lattice are cheap, construction is simple occupy the biggest share in insulation market.
The heat conductivity of EPS granule is low, and thermal and insulating performance is excellent, is preferable insulation material.Portland cement has The excellent properties such as the high and low alkalescence of early strength, proportion is little, fire line good, heat conductivity is little, have the viscous of excellence with EPS granule Knot performance.Haydite is that one is mainly used in architectural engineering insulation, heat insulation, Light Wall, Qing Ji section concrete, structure coagulation The electrodeless Qing Ji section of the aspects such as soil, haydite is mainly based on clay, shale, flyash, colliery overburden, loess, mud etc. Raw material is wanted to make.But it is because excavating clay, shale, loess, mud etc. and can cause soil erosion, environmental pollution, destruction ecology Balance, is therefore not suitable for popularization and application.
Summary of the invention
The present invention proposes a kind of external-wall heat-insulation material, and this insulation material not only combustibility reaches the mark of A level incombustible material Standard, and there is higher intensity and low thermal conductivity.
The technical scheme is that and be achieved in that:
A kind of external-wall heat-insulation material, calculates, in parts by weight including following components: polystyrene foam particles 30~40 Part, portland cement 50~60 parts, slag 10~15 parts, wood fibre 4~6 parts, sodium carboxymethyl cellulose 3~5 parts, foaming agent 0~6 part with water 40~50 parts;Described polystyrene foam particles be lightweight, uniform particle sizes, surface modification and heat-insulation and heat-preservation Grain.
Further, calculate in parts by weight, including following components: polystyrene foam particles 35 parts, portland cement 55 parts, 12 parts of slag, wood fibre 5 parts, sodium carboxymethyl cellulose 4 parts, foaming agent 3 parts and 45 parts of water.
Further, described foaming agent is the mixture of tetrafluoroethane, Pentamethylene. and carbon dioxide.Tetrafluoroethane is utilized (to lead Hot coefficient is 0.0145W/ (m K)) and Pentamethylene. (heat conductivity is 0.012W/ (m K)) low thermal conductivity characteristic, reduce poly- The mean coefficient of heat conductivity of residual gas in styrene foaming product pore, reduces the heat conductivity of Polystyrene heat insulation material.
It is a further object to provide the preparation method of a kind of external-wall heat-insulation material, comprise the following steps:
First weigh required portland cement by formula proportion, slag, wood fibre, sodium carboxymethyl cellulose stir with water Mix to uniform slurry shape material;Foaming agent is added in foaming machine and foams, then foam is injected in Portland cement paste, It is stirred until homogeneous;According still further to formula proportion, polystyrene foam particles is added in foaming Portland cement paste, mix and blend Uniformly, lay alkali-proof glass fiber mesh at mold bottom and pour molding;One layer of grid cloth is finally repaved on slurry surface, Natural curing forms.
Beneficial effects of the present invention:
The external-wall heat-insulation material of the present invention passes through Organic-inorganic composite, utilize EPS granule and portland cement with organic- Prepared by inorganic compounding mode, give full play to organic material light weight, good effect of heat insulation, inorganic material early-strong-fast-hard, fire prevention Property the advantage such as good, its combustibility reaches the requirement of the A level incombustible material that GB8624-1997 standard specifies.Use flyash, mill The industrial residues such as thin slag, levigate colliery powder, silicon ash, turn waste into wealth, have significant energy conservation and environmental protection benefit.Heat conductivity 0.004~0.008w/m.k.
