Abstract

The invention relates to hollow heat-retaining putty which is prepared by the following steps: mineral fiber, heat-response powder and base material gluing auxiliary powder are evenly mixed with a weight proportion of 1.0-2.0:0.2-0.8:89.5-137.3 to prepare the putty, ant the putty is weighted and packaged by bags. The putty overcomes the defects that the prior product has large blocking force, is easy to sag and can not ensure the blow thickness of a coat when being used in construction, the grains of the product are easy to smash when being stirred and blown, and the adhesive force is unsteady. The invention has fire resistance, heat insulation, heat preservation, sound insulation, crack resistance and yellowing resistance, steady structure, long quality guarantee period and low cost, thereby being particularly suitable for the actual need of energy saving in construction engineering.

Description

The hollow heat preservation putty

Technical field:

The present invention is a kind of hollow heat preservation putty that belongs to wall thermal insulating lagging material technical field.

Background technology:

Present normally used wall thermal insulating thermal insulation system, granular polystyrene, polyphenyl extruded sheet, thermal insulation mortar, the construction technology complexity, the bearing capacity of heat insulating layer and construction wall fixedly be rely on organic adhesion agent and steel nail, woven wire fixing, steel nail damages body of wall basic unit; Granular polystyrene, polyphenyl extruded sheet, fire resistance is poor, and deformability is big again, and cost is higher, is easy to generate large-area coming off.According to retrieval; the hollow glass bead mentioned in the technology collected works that beneficial U.S. high molecular polymer institute provided, pearlstone are encircled because light weight in Beijing; barrier force is big during construction; easily produce sagging; can not guarantee the thickness of batch scraping of coating; particle is in stirring and criticize fragmentation easily when scraping, and body of wall and slurry cohesive force are difficult to guarantee the effect of heat insulating and the long-acting performance of quality built on the sand.

Summary of the invention:

The purpose of this invention is to provide a kind of hollow heat preservation putty, a kind of novel have environmental protection, energy-conservation, fire prevention, protection against the tide, sound-absorbing, anti-aging, do not degrade, quality stability is reliable, heat insulating efficient height, easily construction, construction material that cost is low.

The present invention is achieved in that this hollow heat preservation putty is by the ore fiber, the mixture allotment of thermal response powder and the gluing auxiliary powder of base-material is made, described ore fiber, the weight proportion of thermal response powder and the gluing auxiliary powder mixture of base-material is 1.0～2.0: 0.2～0.8: 91.5～139.3 according to this, the three promptly gets putty splitting metering packing after mixing, above-mentioned ore fiber is to be fired by ripe striate gypsum to be ground into, above-mentioned thermal response powder is hybridly prepared into by 2: 1 weight ratios by sheet alkali and weisspiessglanz, and the gluing auxiliary powder mixture of described base-material is with flyash, cement, the hollow ceramic pearl, closed perlite, Vltra tears, redispersable latex powder, the polyethylene micro mist, lignocellulose, the powder of surging is a raw material, according to this by 10.0～30.0: 70.0～85.0: 4.0～8.0: 6.0～12.0: 0.4～0.8: 0.2～0.6: 0.2～0.8: 0.5～1.5: 0.2～0.6 weight ratio is mixed institute and is mixed with, through following prepared:

A, above-mentioned raw materials ore fiber is at first fired through 100 ℃ of temperature by ripe striate gypsum, be ground into 150～400 orders then routinely;

B, the flyash in the gluing auxiliary powder mixture of above-mentioned base-material is removed impurity, be ground into 100～500 orders routinely;

C, the gluing auxiliary powder of various raw ore fibers, thermal response powder and base-material of above-mentioned gained mixed.

Therefrom in the hollow heat preservation putty of the present invention of Huo Deing, because its component ore fiber has extremely strong stability and anti-sag performance, make putty layer be coated with when scraping 8～15mm not disposable that sagging does not ftracture, reduce the pH value of product, reduce the usage quantity of high price tackiness agent, strengthen being coated with the elasticity and the anti-fragility of scraping layer; The thermal response powder is a kind of self-leveling plate, improves water temperature, helps the dispersion that is difficult to the dissolved coarseparticulate in gluing, strengthens the gelling and the weather-resistant property of product; Flyash is to utilize the elasticity of cinder to reduce the fiery and forthright property of cement, utilizes the fibrous expansion texture of cinder, strengthens heat insulation effect, and cement to be other materials be difficult to the rigid gelling material of displaced inorganic aquation; The hollow ceramic pearl is the heat preserving and insulating material that a kind of and cement, organic adhesion agent both have affine cohesive force, has characteristics such as fire prevention, electrical insulation capability are good, uniform particles, water-intake rate is low, free-running property good, flintiness is strong, shrinkage coefficient is little; Closed perlite is by having certain particle diameter, inside keeping complete porous, hollow hollow structure, product has kept the purity of perlite natural inorganic Chemical Composition, the characteristics that conventional expanded perlite water-intake rate is big, intensity is low, flowability is poor have been overcome, extend the Application Areas of pearlstone, had high strength, light weight, heat insulating, characteristics such as electrical insulation capability is good, purity is high, uniform particles, water-intake rate is low, free-running property is good; Vltra tears is a kind of gluing powder of organic water conservation that can be dissolved in water fast, can make cement maintain the effect of high water conservation, reduces the frictional coefficient of particle object, improves the lubricity of product, well protective colloid; Redispersable latex powder can improve the force of cohesion of material, improves workability, prevents the dry too fast of cement, has high-flexibility, high-weatherability and to the high-adhesion of various base materials; The polyethylene micro mist can increase the plasticity-of material, increases anti-folding resistance to impact shock and wear-resisting weather-proof, increases clinging power, flowability of cement, mortar and slows down cement surface time of drying, and the increase coating adaptability prevents the be full of cracks of cementitious coating; Lignocellulose can obtain the fiber reinforcement effect and the thickening power of product, improves thixotropy and bleeding resistance, improves stability, strengthens anti-the contraction and anti-cracking performance, prolongs the operating time, has good snappiness, dispersiveness and unreactiveness; The powder of surging is a kind of prevent liquid water or effect capillaceous, penetrates solidified material, reduces the problem of sealing of returning, and reduces the water-intake rate of base material.Therefore the hollow heat preservation putty that becomes by the above-mentioned raw materials hybrid process it solved hollow glass bead, pearlstone because in light weight; barrier force is big during construction; easily produce sagging; can not guarantee the thickness of batch scraping of coating; particle is in stirring and criticize when scraping broken easily; with body of wall and slurry cohesive force built on the sand, be difficult to guarantee the effect of heat insulating and the long-acting performance issue of quality.It is insecure to have overcome expanded polystyrene veneer polyphenyl plate heat preserving system common styrofoam and base adhesive in engineering practice, promptly use screw to reinforce, yet exist come off and the hidden danger of safety (because of clenching bad admittedly or the time one is grown, nail meeting corrosion), the fire line of granular polystyrene is very poor in the expanded polystyrene veneer polyphenyl board exterior wall heat insulation system, one meets fire, and whole heat-insulation system will soon be burnt.And construction costs is higher, and difficulty of construction is big, time-consuming problem.From cost performance, the hollow heat preservation putty obviously is better than the heat preserving and insulating material of other heat insulating layer, is fit to very much the energy-conservation actual needs of construction work.
