Description

A kind of exterior wall heat-insulating board
Technical field
The present invention relates to a kind of warming plate, in particular, it relates to the powder filled modified a kind of exterior wall heat-insulating board of a kind of Tourmaline.
Background technology
In recent years, because environmental consciousness constantly causes the attention of scientific circles in people's life, energy-saving and emission-reduction are widely known reason especially, therefore a large amount of insulating products has appearred, particularly the external wall body thermal insulation of building trade adopts especially one after another, so, the numerous and confused development of each large scientific research institution and private enterprise external-wall heat-insulation material of different nature, as: the warming plate that resin cotton, glass wool, aluminium silicate wool, rock wool are made, rubber sheet, polystyrene board, polyurethane sheet, phenolic board etc., but these all exist certain disadvantage.The warming plate that resin cotton, glass wool, aluminium silicate wool, rock wool are made, bad mechanical strength with the poor adhesion of cement, is easily peeled with body of wall, non-watertightly is easy to bursting by freezing; And rubber sheet, polystyrene board, polyurethane sheet, phenolic board are inflammable especially, and cost is high, and it is very large that the said products pollutes in process of production, most importantly do not reach the requirement of the A level product of national regulation.Therefore, the extensive application of the said products causes fire frequently, and wall insulating layer comes off, and causes serious financial loss and personnel safety accident.From the fp angle, replacing the organic heat-insulating plate with inorganic heat-insulation board has become the developing direction that present external wall insulation uses.In the inorganic non-combustible material, multicellular glass, foamed ceramics have certain occupation rate, but these things are on the high side, and poor toughness, and unit weight is large, are unfavorable in building trade particularly promoting the use of aspect the exterior-wall heat insulation.Relatively comprehensive, it is low that the foam cement that contains a large amount of sealed porositys has cost, production technique is simple, good insulation, heat-proof quality and physical strength preferably, topmost characteristics are not burn, pollution-free in the production process, therefore be widely used in Building Trade in China, but the warming plate that this common cement foaming material is made is because volume to weight ratio is larger, can only be applicable to the fire-blocking belt, the spatial separation of general framework building, the insulation on roof and floor is not suitable for the insulation of external walls of building.Therefore develop a novel inorganic external wall thermal-insulation plate, imperative.
Summary of the invention
Purpose of the present invention just provides that a kind of unit weight is light, strong adhesion, good, the economic environmental protection of physical strength, cost are low, do not burn, heat insulation and preservation effect is good, be easy to cutting and construction, has a kind of exterior wall heat-insulating board of negative ion-releasing function.
In order to achieve the above object, the present invention is achieved in that a kind of exterior wall heat-insulating board, by cement slurry and foam composition, cement slurry is: Tourmaline powder, cement, terra alba, active admixture, re-dispersible glue powder, tackiness agent, ether of cellulose, water reducer, hydrophober, fortifying fibre, water.Foam raw material is: whipping agent, suds-stabilizing agent, water.Its raw material consumption mass ratio is as follows:
1. cement slurry is pressed following weight part proportioning:
Tourmaline powder 0.8-1.5 part
100 parts of cement

2. foam is by following weight part proportioning
1 part of whipping agent, suds-stabilizing agent 0.3-1 part, water 40-60 part
Described cement slurry and prefabricated foam wt blending ratio are 1: 1, and wherein the volume density of foam is every cubic metre of 70-75 kilogram.
Above-mentioned Tourmaline powder is that the particle that the Tourmaline ore obtains by pulverizing is the powder of 0.3 μ m, function with anion releasing, described cement is 42.5 grades of quick hardening sulphoaluminate cements, terra alba is that gesso has micro-expansibility, can reduce the shrinkage strain of foam cement, active admixture is flyash, the weight that both can alleviate foam cement can also improve the intensity in foam cement later stage, can be cold cut property polyethylene alcohol powder disperseing rubber powder, can improve the cohesion of foam cement, flexibility and elasticity, tackiness agent is 801 glue for building, physical strength that can enhanced foaming cement, ether of cellulose is the first class ether of cellulose, has water retention, water reducer is the amino acid high efficiency water reducing agent, can improve the flowability of cement slurry, hydrophober is organosilicon moisture repellent, reduce the water-intake rate of foam cement, whipping agent is compound foaming agent, suds-stabilizing agent is empgen BB, fortifying fibre is chopped engineering polypropylene fibre, splitting resistance that can the enhanced foaming cement later stage, enhance mechanical strength.
After adopting such scheme, the invention has the beneficial effects as follows:
1, the Tourmaline powder as stopping composition is a kind of pulvis that has at normal temperatures long-term negative ion-releasing function, can purify air.
2, do not burn.
3, has good sound-insulating performance.
4, good with the avidity of body of wall, do not chap, do not peel, unit weight is light, physical strength good.
5, cost is low.
