The preparation method has the advantages that the defect that an insulation material of a normal wall cannot be automatically maintained is solved, the absorption and discharging of the moisture are automatically balanced, the problems of cracking, hollowing, falling and the like occurring after the construction are solved, complex working procedures for utilizing gridding cloth and the like are omitted, the construction difficulty under the normal temperature is low, and the energy conservation and environmental protection requirements are met.
Description
Technical field
The present invention relates to a kind of material for body of wall, particularly light composite heat-preserving fire-type dry-mix and compound method thereof.
Background technology
General wall heat insulation material mainly adopts rubber powder urethane, cement as coagulated material at present, aggregate mainly adopts calcium silicate board with microporous, styrofoam, extruded sheet organic material or traditional inorganic materials, and existing general wall heat insulation material has the following disadvantages: do not prevent fires, ultimate compression strength is low, deformation coefficient is large, safety and firmness is poor, easy to crack, heat insulating coefficient is low, not energy-conservation, easily cause that environmental pollution, difficulty of construction are large, cost is higher.Do not meet fire prevention, energy-saving and environmental protection, easily construction, requirement cheaply.
Summary of the invention
The present invention is in order to overcome above-mentioned deficiency, one maintenance is voluntarily provided, self-poise moisture absorption and discharge, and constructed and be difficult for out drum afterwards, come off and light composite heat-preserving fire-type dry-mix that can be effectively energy-conservation, the collocation method of this dry-mix is provided simultaneously.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical programs: a kind of light composite heat-preserving fire-type dry-mix, by the raw material of the following weight proportion wood fibre 1-3 part that is made, hydroxypropyl methyl fiber 3-6 part, polypropene staple 3-7 part, : resin type re-dispersible glue powder 5-8 part, dicalcium powder 80-120 part, white lime 80-120 part, flyash 80-120 part, cement 600-800 part, glass bead 300-500 part, molasses 2-4 part, sulfonated lignin 3-6 part, calcium formiate 5-6 part, high efficiency water reducing agent 1-2.5 part, thixotroping lubricant 1-3 part, concrete waterproofer 3-5 part, air entrapment agent 0.1-0.4 part.
Most preferably scheme of the present invention is: a kind of light composite heat-preserving fire-type dry-mix, raw material by following weight proportion is made: wood fibre 1.5-2.5 part, hydroxypropyl methyl fiber 4-5 part, polypropene staple 3.5-5.5 part, resin type re-dispersible glue powder 5.5-7 part, dicalcium powder 90-105 part, white lime 80-120 part, flyash 80-120 part, cement 650-750 part, glass bead 350-400 part, molasses 1-3.5 part, sulfonated lignin 4-5 part, calcium formiate 3-5 part, high efficiency water reducing agent 1.5-2 part, thixotroping lubricant 1.5-2.5 part, concrete waterproofer 3-4 part, air entrapment agent 0.1-0.3 part.
Preparation method of the present invention is: get the raw materials ready by the weight ratio of above-mentioned each component, in fine material mixer, first add hydroxypropyl methyl fiber, wood fibre, polypropene staple, fully stir, add again cement, dicalcium powder, flyash, white lime, after fully stirring, add glass bead, molasses, sulfonated lignin, calcium formiate, resin type re-dispersible glue powder, thixotroping lubricant, high efficiency water reducing agent, concrete waterproofer, air entrapment agent, fully be uniformly mixed, more than operate under normal temperature and pressure and sealing condition and carry out, the mixing speed of described stirrer is 30-100r/min.
Core of the present invention is that the alternative traditional common rubber powder of low-carbon (LC) final resin type re-dispersible glue powder that the reproducible natural macromolecular material of screening is main raw material is made coagulated material, adopts flyash to substitute the organic materials such as traditional calcium silicate board with microporous, styrofoam, extruded sheet as lightweight reactive aggregate.Can there is gelling reaction at redispersion rubber powder, molasses, sulfonated lignin, calcium formiate and cement, flyash etc. in resin type, generate new gelling thing, new gelling thing has stronger sustainability maintenance and the ability of equilibrium water gas, can keep the stable of mortar later stage cohesive strength and constantly increase its intensity, moisture content in energy balance mortar, prevent that percolating water and body of wall aqueous vapor from assembling, dewfall, effectively control and reduce the drying shrinkage of cement, increase plasticity, prevent out that bag is poly-, hollowing, come off.New gelling thing can infiltrate in the shallow table cavity of glass bead pore, and glass bead is coated, and connects each particle formation intensity higher; dense, the better thermal insulation separation thermosphere of stability, the ultimate compression strength of raising glass bead; water tolerance, reduces water-absorbent, reaches fp object simultaneously.Add thixotroping lubricant and improve grey evenness and the cracking resistance ability of mixing.Add high efficiency water reducing agent and reduce pore quantity, improve system compactness and anti-permeability performance.Add concrete waterproofer and reduce system water regain, improve heat-insulating property and ventilation property.
