Abstract
The invention provides an energy-saving heat-insulating wall composite material for energy-saving environment-protecting eco-friendly rooms, in particular a formulation and a technique for magnesite cement-cast energy-saving heat-insulating walls containing bamboo reinforcement ribs. The formulation comprises the following components (in percentage by weight): 58 percent of industrial-grade magnesium oxide containing 85 percent of magnesium oxide, 21.6 percent of industrial-grade magnesium chloride containing 50 percent of magnesium chloride, 2 percent of polyvinyl alcohol, 0.6 to 1.6 percentof organosilicon hydrophobic agent, 1 to 2 percent of ammonium bicarbonate or ammonium carbonate serving as foaming agent, a proper amount of short fiberglass bright silk or raw silk for reinforcementand medium alkali, and 17.5 percent of water. The process comprises the following steps: (1) adding magnesium chloride to water, fully stirring for dissolving and obtaining a magnesium chloride aqueous solution 1; (2) adding polyvinyl alcohol to water at 90 DEG C, fully melting the polyvinyl alcohol and obtaining a solution 2 containing 6.7 percent of polyvinyl alcohol; (3) adding organosilicon waterproof agent to the mixture of the solutions 1 and 2, evenly stirring and obtaining a solution 3; (4) adding magnesium oxide to the solution 3, evenly stirring and obtaining pasty slurry 4; (5) adding the foaming agent to the pasty slurry 4 and evenly stirring; and (6) casting energy-saving heat-insulating walls which are added with bamboo ribs and shaped by templates in the slurry.
Description
One, technical field
The energy-saving heat-insulating composite material that a kind of energy-saving, environment-friendly and ecological room is used, particularly a kind of prescription and Technology of energy-saving heat-insulating of the magnesite cement-cast that contains the bamboo stiffening web.
Two, background technology
2006 with Beijing energy-conserving and environment-protective exhibition in 2007 on, all released the architectural mode in the ecological, environmental protective room of ecological energy-saving farmhouse, adopted the technology of foamed bricks building energy conservation heat insulation body of wall, this ecological room pattern energy-conserving and environment-protective cost is low, the on-the-spot quantity ordered of exhibition in 2007 surpasses 5000 covers, demonstrate and have the strategic market requirement, but the body of wall mechanical property in this room is relatively poor, have to its sealing in two layers the cabin exhibition, forbid making a visit on the people, have an accident in case collapse, this shows to have and improve the necessity that improves.
Three, summary of the invention
The objective of the invention is to invent the body of wall that a kind of perfusion that is similar to cement steel that replaces reinforcing bar to make stiffening web with bamboo reinforcement becomes, the perfusion material of this body of wall adopts surface halide accumulation resistance to return the magnesite cement foamed village material of frost, thereby reach the purpose of body of wall energy-saving heat preserving, overcome the shortcoming of general magnesite background technology.
The prescription of magnesite cement foaming material of the present invention (weight %) is:
Contain the technical grade magnesium oxide 58% of magnesium oxide 85%, the technical grade magnesium chloride 21.6% that contains magnesium chloride 50%, polyvinyl alcohol 2%, organosilicon moisture repellent 0.6～1.6%, whipping agent ammonium hydrogencarbonate or carbonic acid ammonia 1～2%, strengthen with staple glass fibre boiled-off silk or raw silk, middle alkali is an amount of, water 17.5%.
Production technique of the present invention is as follows
1. magnesium chloride being added in the entry fully, stirring and dissolving gets magnesium chloride brine 1;
2. make the solution 2 that contains polyvinyl alcohol 6.7% with in 90 ℃ of water of polyvinyl alcohol adding it fully being dissolved;
3. waterproofing agent of organosilicon is added stir in the mixed solution of solution 1,2 solution 3;
4. magnesium oxide is added stir in the solution 3 pasty slurry 4;
5. whipping agent is added in the pasty slurry 4 and stir;
6. being added with bamboo reinforcement with this slurry perfusion is got final product by the energy-saving heat-insulating wall that template formalizes.
Advantage of the present invention and positively effect
1. magnesite cement foamed dabbling body of wall of the present invention has bamboo reinforcement, has guaranteed that body of wall integral body has firm mechanical property.
2. magnesite foaming bottling wall of the present invention is in light weight, economize raw material, heat preservation and energy conservation effects is good, and overcome general magnesite and return the shortcoming that halogen returns frost, further improved the quality of body of wall.
3. the foaming of employing foaming slurry perfusion body technology, surface halide accumulation resistance etc. are multi-functional once finishes, and the material technology cost is all low, and performance improves greatly, has to utilize to apply.
Four, embodiment
Identical among the prescription (weight %) of magnesia cement body of wall of the present invention perfusion slurry and construction technology and top three.
