Description
Technical field
The invention belongs to construction materials and technical field of building construction, and in particular to a kind of sprayable heat preservation sand of high water resistance
Slurry.
Background technique
When desulfurized gypsum refers to the sulfur dioxide in use lime-lime stone recycling fire coal or cooking fume, the work of generation
Industry solid waste, the immense pressure that the bulk deposition of desulfurized gypsum generates environment.Conventional vacuum mortar is cementing with cement base
Material, expansion polystyrene are lightweight aggregate, and shrinking percentage is big, and easy cracking, heat insulation effect is poor, heat-proof quality is poor, fire protecting performance
Difference, and not can be recycled, the problem of causing environmental pollution, high resource consumption, high-energy source consumption.
Summary of the invention
The present invention overcomes the shortcomings of the prior art, provides a kind of sprayable thermal insulation mortar of high water resistance, solves traditional sand
Starch the low problem of poor water resistance, intensity.The present invention is achieved through the following technical solutions.
A kind of sprayable thermal insulation mortar of high water resistance, the raw material including following parts by weight: 70 ~ 200 parts of desulfurized gypsum；Vitreous is micro-
20 ~ 50 parts of pearl；10 ~ 50 parts of cement；10 ~ 30 parts of flyash；5 ~ 20 parts of silicon ash；0.5 ~ 5 part of HPMC；Polypropylene fibre 0.1 ~ 1
Part；0.2 ~ 5 part of redispersible latex powder；1 ~ 10 part of styrene-acrylic emulsion；2 ~ 15 parts of polyvinyl alcohol；0.01 ~ 1 part of citric acid；Water 150
~ 350 parts.
It, can be with gypsum due to the polycarboxylic acid molecule that citric acid is hydroxyl when the present invention uses citric acid as retarder
The calcium ion on surface occurs complex reaction and generates stable calcium citrate complex compound, which can be adsorbed on gypsum particle table
Face achievees the effect that slow setting to inhibit the hydration reaction of gypsum, to realize sprayable property of the thermal insulation mortar in construction；
When using HPMC as polymer, macromolecule polymer material can be used as a kind of stress absorption film, itself belong to a kind of flexible, tough
Property, highly elastic material when caning absorb the development of mortar basic crack the ess-strain that generates played to hinder the development in crack
The effect of cracking resistance.
Preferably, the polyvinyl alcohol is the modified polyvinyl alcohol of graft crosslinking.Modified poly ethylene alcoholic solution substitution one
Part water, to achieve the purpose that reduce water absorption rate.
Preferably, the partial size of the glass bead be 10 ~ 30 mesh, 30 ~ 50 mesh, 70 ~ 90 mesh one of which or its
Meaning combination.
Preferably, the cement is portland cement or magnesium oxysulfide concrete or combination of the above.
A kind of sprayable thermal insulation mortar preparation method of high water resistance: by the desulfurized gypsum, glass bead, cement, fine coal
The abundant dry mixing in blender of ash, silicon ash, HPMC, polypropylene fibre, redispersible latex powder, polyvinyl alcohol is mixed to form dry
Mixing；After again mixing water and styrene-acrylic emulsion, citric acid, it is added in the dry blend, stirs evenly to get the heat preservation sand
Slurry.
The sprayable thermal insulation mortar preparation method of high water resistance can also are as follows: using maleic anhydride or epoxy resin to polyethylene
It is modified that alcohol carries out graft crosslinking, then the desulfurized gypsum, glass bead, cement, flyash, silicon ash, HPMC, polypropylene is fine
The abundant dry mixing in blender of dimension, redispersible latex powder, modified polyvinyl alcohol is mixed to form dry blend；Finally by water
After styrene-acrylic emulsion, citric acid mixing, it is added in the dry blend, stirs evenly to get the thermal insulation mortar.
Graft crosslinking is carried out to polyvinyl alcohol using maleic anhydride or epoxy resin to be modified, and is then mixing and stirring mortar
When, modified poly ethylene alcoholic solution substitutes a part of water, to achieve the purpose that reduce water absorption rate.
The present invention problem high for conventional gypsum base thermal insulation material water absorption rate, while improving water resistance, so that its
Adhesion strength greatly improves.Desulfurized gypsum base thermal insulation mortar category inorganic heat insulation material, it is "dead", pollution-free, it is used as interior wall and protects
Adiabator is more comfortable, more healthier than organic styrofoam, polyphenyl particle heat-insulating mortar.And the use of desulfurized gypsum improves its money
Sourceization efficiently utilizes, and promotes the further development of national environmental protection circular economy, while reducing the yield of ore cream, is pushing away
The development of green building material has been driven while dynamic efforts at environmental protection.
The present invention is generated compared with the existing technology to be had the beneficial effect that.
The present invention has both the characteristics of heat preservation and excellent mechanical performances again while meeting spraying application, by adding lemon
Acid can increase the presetting period of thermal insulation mortar, and not influence final mechanical strength；Polypropylene fibre and glass fibre is added
It can inhibit mortar cracking, reduce the dry of mortar early stage and shrink, the continuity of amplified medium material；It is added what graft crosslinking was modified
Polyvinyl alcohol can greatly improve the water resistance of material, while polyvinyl alcohol has the function of certain foam stabilizing, generate foaming agent
Foam is uniform, stablizes, to reduce the thermal coefficient of thermal insulation mortar.
The present invention uses the solid waste such as desulfurized gypsum, flyash to meet country as the raw material of production thermal insulation mortar
Resource-conserving, environmentally friendly policy.The sprayable thermal insulation mortar of the high water resistance being prepared into both had met the requirement of spraying application,
Thermal property is led with high-intensitive, low again.
