Description
Technical field
The present invention relates to a kind of novel environment friendly magnesium oxide foam material.
Background technology
Inorganic materials has that intensity is high, fire protection flame retarding security is good, thermal property is good, it is convenient to construct, stability is high, the non-harmful feature of environmental protection, is therefore widely used in building field, as made lagging material or fire-retardant material uses.Common magnesium cement material has the performances such as intensity is high, fire-resistant, anticorrosion, is the one that in inorganic materials, prospects for commercial application is higher.But other lagging material of volume to weight ratio of common magnesium cement is large, constrains the development of common magnesium cement as lagging material.For this shortcoming, current common way reduces its unit weight by adding whipping agent, or do not add magnesium chloride, reduces burn into and return halogen, moisture absorption phenomenon, or the function reaching control noises, purify air while foaming.
Generally speaking, the whipping agent of use generates bubble due to reaction or generates bubble due to decomposition, and the addition of whipping agent increases with the unit weight reduction of goods.A kind of magnesite cement foaming material is disclosed for this feature CN1115308A, tensio-active agent is wherein used to reduce the surface brute force of slurry, the interfacial state of change system, thus produce wetting or dewetting, emulsification or breakdown of emulsion, a series of effects such as foaming or froth breaking, to control size and the structure of goods pore, control the unit weight of goods simultaneously.But be wherein mixed into bittern, because chlorion can the continuous moisture absorption and have corrodibility, thus goods inevitably occur that halogen and moisture absorption phenomenon are returned in burn into surface, cause unstable properties.
CN1075472A discloses a kind of light foamed building material containing magnesium, wherein in order to intensity and the toughness of strongthener, adds the filler such as aggregate and cellulosic, and finally having made unit weight is 200-1000kg/m
3goods.But need to add appropriate minor glue agent to use together, as the soluble magnesium such as magnesium chloride, magnesium sulfate salts solution.And the whipping agent adopted is single whipping agent.
In order to solve the moisture absorption and the corrosion problems of magnesium oxide and magnesium chloride and the rear chlorion of hydrogen peroxide foaming, CN101851111A discloses a kind of PLASTIC LAMINATED, is made up of the raw material of following weight part: magnesium oxide 500-1000 part, magnesium sulfate 60-120 part, kaolin 200-500 part, phosphoric acid 20-30 part, hydrogen peroxide 50-200 part, water 50-200 part.This product not magnesium chloride containing, and adopt magnesium sulfate as minor glue agent, therefore have corrosion-free, without returning halogen, without moisture absorption phenomenon, environment-protecting asepsis.But its shortcoming is to add proportion.
CN102101787A discloses a kind of magnesium cement foam material, pressed the weight percent mixing of 10-90%, 5-89%, 0.8-10% by light-magnesite powder, filler and compound foaming agent after, with the 100-150% mix magnesium chloride solution of mixture total weight amount, through stirring, casting and get final product.Wherein use the composite foamable agent mixed by the mass ratio of 90-95%, 1-6%, 1-5% by superoxide, treating compound, suds-stabilizing agent, have that expansion rate is fast, the feature of uniform in foaming, unit weight is 400-900kg/m
3, thermal conductivity is 0.06-0.25W/ (M.K), and thermal resistance is about the 10-20 of normal concrete doubly.
CN103265317A discloses a kind of powdered magnesia whipping agent, is made up of light magnesium oxide, high sticky attapulgite clay powder, activated attapulgite, sodium lauryl sulphate, SPC-D, sodium polyacrylate, sodium pyrosulfate and poly-naphthalene formaldehyde sulfonate salt.This product is for pouring into a mould foam product, layering is there will not be in casting process, the product stripping time is shorter, gas contains a certain amount of oxygen, be conducive to the air ambient protecting working-yard, and with uses merely compared with sodium lauryl sulphate, better, hole size is more even for the froth stability of compound foaming agent; The product produced not only can effectively pollute by control noises, the function being incubated in addition and purifying air.
As can be seen from the development of above-mentioned magnesium oxide foam material, use the advantage of the more single whipping agent of composite foamable agent obvious, simultaneously along with the variation of the market requirement, also more and more abundanter to the requirement of magnesia foamed material, from initial unit weight requirement, high-strength light till now and can sound-deadening and noise-reducing, the multiple demandization development purified air.During simple use superoxide foaming, bubble formation is fast, but also there is partial rupture in bubble, i.e. less stable, thus not only need the bubble production volume controlling unit volume, also need the stability and the homogeneity that control bubble, generally can by adding appropriate suds-stabilizing agent to control, control the structural stability of air bubble liquid-membrane, give elasticity and the self-reparing capability of have good lather.In addition, for the extra demand purified air, can by adding appropriate filler to realize, as attapulgite clay powder etc.But the realization of additional functionality can increase the cost of raw material usually, as the process etc. of attapulgite clay powder, be unfavorable for suitability for industrialized production on a large scale.
Summary of the invention
In sum, the object of the present invention is to provide a kind of intensity high, the low and magnesium oxide foam material of low cost of unit weight.
A kind of novel environment friendly magnesium oxide foam material of the present invention, is characterized in that: this material feedstock comprises the compound foaming agent of the light-magnesite powder of 80-90 weight part, the fleut of 5-15 weight part and 1-10 weight part.
Described light-magnesite powder refers to that, by the light calcined magnesia of magnesite at 700-850oC temperature lower calcination, the content of magnesia wherein in light-magnesite powder is 75-80%.
