Description
Technical field
The present invention relates to a kind of warming plate, in particular, it relates to a kind of a kind of Multifunction foam cement plate that is applied to building trade.
Technical field
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 seriation insulating products has appearred, particularly building trade adopts especially one after another, so, the numerous and confused development of each big scientific research institution and private enterprise external-wall heat-insulation material of different nature, the heat insulating inner wall material, fire-blocking belt product etc., as: resin cotton, glass wool, aluminium silicate wool, the warming plate that rock wool is made, rubber sheet, polystyrene board, polyurethane sheet, phenolic board etc., but these products all exist certain disadvantage: resin cotton, glass wool, aluminium silicate wool, the warming plate that rock wool is made and the poor adhesion of cement, easy and body of wall decortication, physical strength is bad, non-watertightly is easy to bursting by freezing; And rubber sheet, polystyrene board, polyurethane sheet, phenolic board are inflammable especially, and the cost height, and above product also produces very big environmental pollution in process of production, and a topmost weakness is the requirement that does not reach the A level product of national regulation.Therefore, the extensive application of the said products, cause frequently as: fire, thermal insulation layer decortication, cause serious economy loss and personnel safety accident.From the fp angle, replacing the organic heat-insulating plate with the inorganic heat preservation plate has become present external wall insulation, fire-blocking belt, the developing direction that thermal insulation of roof, floor insulation are used.In inorganic not so material, multicellular glass, foamed ceramics have certain occupation rate, but these things are on the high side, and poor toughness, and unit weight is big, only are applicable to specific place, are unfavorable for promoting the use of in building trade.Comprehensive relatively it is low that the foam cement that contains a large amount of sealed porositys has cost, and production technique is simple, pollution-free in the production process, have good insulation, heat-proof quality and physical strength preferably, topmost characteristics are not burn, therefore, series product are widely used in Building Trade in China.But, the warming plate that this common foam cement material forms, because volume to weight ratio is bigger, the bad control of bubbles volume, can only be applicable to the fire-blocking belt, and the insulation on spatial separation, roof and the floor of general framed building, because weight is big, bubble is uneven, physical strength is irregular, use range is affected, more can not be applicable to the insulation of external walls of building, therefore develop aly have that unit weight is light, machinery slightly good, encapsulated bubble evenly, the novel multifunctional foam cement plate of good heat insulating, imperative.
Summary of the invention
Purpose of the present invention just provides that a kind of physical strength is good, encapsulated bubble is even, unit weight is controlled, does not burn, strong adhesion, economic environmental protection, cost is low, heat insulation and preservation effect good, be easy to a kind of Multifunction foam cement plate of cutting and constructing.
In order to achieve the above object, the present invention is achieved in that a kind of Multifunction foam cement plate, be made up of cement slurry and foam, cement slurry is: cement, terra alba, active admixture, hydrogen peroxide, re-dispersible glue powder, 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:

2. foam is by following weight part proportioning
1 part of whipping agent, suds-stabilizing agent 0.2-0.9 part, water 40-60 part
Described cement slurry and prefabricated foam wt blending ratio are 1: (0.1---0.9), wherein volume of foam density is every cubic metre of 50--100 kilogram.
Described cement is 42.5 grades of silicate 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 later stage, hydrogen peroxide is industrial hydrogen peroxide, has the effect that improves the foam cement physical strength, can be cold cut property polyethylene alcohol powder disperseing rubber powder, can improve the cohesion of foam cement, flexibility and elasticity, ether of cellulose is the first class ether of cellulose, has water retention, and water reducer is the amino acid water reducer, can improve the flowability of cement slurry, hydrophober is organosilicon moisture repellent, reduces the water-intake rate of foam cement, and whipping agent is compound foaming agent, suds-stabilizing agent is empgen BB, fortifying fibre is short cut journey 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, do not burn.
2, have good sound insulation, heat insulation, heat-insulating property.
3, the avidity with body of wall is good, does not chap, does not peel.
4, the function that has antidetonation, hydrophobic.
5, low, the production process non-pollution discharge of cost.
6, goods rate of closed hole height, good uniformity.
7, unit weight is adjustable, and physical strength is good.
A kind of Multifunction foam cement plate of the present invention, be a kind of fire prevention, energy-conservation, physical strength good, the porous, inorganic thermal insulation material that can cut out arbitrarily, is applicable to that ground insulating, body of wall play the shielding of partition, thermal insulation of roof, exterior-wall heat insulation, fire-blocking belt, noise source etc.
