Abstract
The invention relates to a surface mortar for an outer wall external insulation system using sprayed rigid foam polyurethane. The surface motor is prepared by mixing the following materials in proportion (mass): 40 to 58% of cement, 20 to 35% of a lightweight insulation material, 0.1 to 0.2% of an anti-cracking agent, 0.4 to 1% of redispersible rubber powder, 0.2 to 0.3% of a water-retaining agent and 0 to 0.5% of slow-drying agent, with the balance being a filler. The surface mortar provided in the invention has good flexibility and crack resistance, can compensate for temperature strain caused by difference among expansion coefficients of materials and avoids the cracking of the external insulation system, thereby thoroughly overcoming the difficulty in leveling and the problem of proneness to cracking in the prior art. Simultaneously, a conventional process for leveling of insulation mortar and rendering of crack resistant mortar is simplified in the invention; the surface mortar provided in the invention has both the functions of leveling and rendering and has excellent leveling and filling performance and a light weight, providing reliable guarantee for the security of the system. Low cost and substantially reduced construction cost are achieved in the invention.
Description
Technical field
The present invention relates to a kind of spraying hard bubble polyurethane exterior wall outer heat preservation system plastering mortar, relate to building material technical field.
Background technology
In the external thermal insulation system of buildings, polyurethane thermal insulation system is a kind of of comparatively novelty, also has many improved places of needs though the hard polyurethane foam spraying is used for external wall outer insulation, and the advantage of this technology is clearly.Spraying polyurethane is high with general materials for wall cohesive strength owing to hard bubble, need not any tackiness agent and anchoring piece, and be a kind of natural adhesive material, can form the successive thermal insulation layer.It has the advantage of following ten aspects: 1, insulation usefulness is good; 2, stability is strong; 3, fire resistance is preferably arranged; 4, heat resistance excellent property; 5, the impact resistance performance is better than lagging materials such as EPS; 6, strong to agent structure distortion adaptive faculty, resistance to cleavage is good; 7, weather resistance satisfies requirement in 25 years; 8, has good construction performance; 9, for ease of maintenaince property is strong; 10, good environmental protection.But there is the difficult problem of difficult levelling in polyurethane thermal insulation system.
Behind the spraying hard-foam polyurethane, need with alignment material such as thermal insulation mortar levelling spray coating polyurethane rigid foam thermal insulation layer, re-use plastering mortar and criticize and be coated with.Its complex process, the technology cost is high.
Above-mentioned spraying hard bubble polyurethane exterior wall outer heat preservation system of the prior art uses plastering mortar to be miscellany, and (quality) is mixed in proportion forms by following material:
Cement 37.7%
Ash calcium 5%
Medium sand 55%
Redispersible rubber powder 2%
Auxiliary agent 0.3%.
Above-mentioned spraying hard bubble polyurethane exterior wall outer heat preservation system plastering mortar of the prior art, its shortcoming is: function is more single, and is easy to crack, and the technology cost is high, need improve.
The present invention aim to provide a kind of planeness better, not easy to crack, spraying hard bubble polyurethane exterior wall outer heat preservation system plastering mortar that cost is low.
Summary of the invention
Technical solution of the present invention is following:
A kind of spraying hard bubble polyurethane exterior wall outer heat preservation system plastering mortar is characterized in that: (quality) is mixed in proportion forms by following material:
Cement 40-58%
Light heat insulation material 20-35%
Anti-fissuring agent 0.1-0.2%
Redispersible rubber powder 0.4-1 %
Water-holding agent 0.2-0.3%
Drying retardant 0-0.5%
Surplus is a weighting agent.
The present invention has good snappiness and splitting resistance, can compensate the temperature strain that the difference because of the material coefficient of expansion produces, and avoids the outer heat preservation system cracking, has thoroughly solved the difficult levelling of traditional technology, a difficult problem easy to crack.Simultaneously traditional thermal insulation mortar levelling is added the work simplification that anticracking grout is wiped one's face, integrate levelling and the function of wiping one's face, levelling, filling properties are excellent, and light specific gravity, for the security of system provides reliable assurance.Its fillibility is good, and filling thickness 10mm needs 7kg/ ㎡, has solved problems such as planeness, cracking, cost.
Further technical scheme is:
Above-mentioned light heat insulation material is one of glass bead, granular polystyrene.
Further technical scheme is:
Above-mentioned anti-fissuring agent is one of polypropylene fibre, wood fibre.
Make anti-fissuring agent with polypropylene fibre, wood fibre, the increase effect of prestressed is good and proportion is little.
Further technical scheme is:
Above-mentioned water-holding agent is one of hydroxypropylcellulose, calcium sulphate retarder.
Further technical scheme is:
Above-mentioned light heat insulation material is a glass bead.
Adopt that glass bead improved mortar with easy mobility and anti-certainly intensity, reduce the wood property shrinking percentage, improved over-all properties and workabilities such as heat-insulating property, ageing-resistant performance, weather resistance simultaneously.
Further technical scheme is again:
Above-mentioned weighting agent is a quartz sand.
The present invention adopts quartz sand as weighting agent, replaces available technology adopting ash calcium powder as weighting agent, has increased cohesive strength, forms certain intensity, has reduced applying pass simultaneously, has improved the cracking resistance effect.
Said drying retardant is one of X 2073, polyvinyl alcohol, Ucar 35.
The present invention sprays the detection data that the hard bubble polyurethane exterior wall outer heat preservation system compares with plastering mortar with plastering mortar and spraying hard bubble polyurethane exterior wall outer heat preservation system of the prior art:
Spraying hard bubble polyurethane exterior wall outer heat preservation system plastering mortar provided by the invention; Can directly criticize and be coated on the polyurethane rigid foam material; Its planeness is better; Not easy to crack; Cost is low; Having saved simultaneously needs the operation with alignment material such as thermal insulation mortar levelling spray coating polyurethane rigid foam thermal insulation layer, and construction cost greatly reduces.
Further more again technical scheme is:
(quality) is mixed in proportion forms by following material in the present invention:
Cement 55%
Glass bead 20%
Polypropylene fibre 0.15%
Redispersible rubber powder 1%
Hydroxypropylcellulose 0.2%
X 2073 0.3%
Surplus is a quartz sand.
Through the analytical test contrast, the present technique scheme has tangible advantage, and the one, cohesive strength is higher than other scheme, and this programme can reach 0.18MPa.The snappiness of product is good, show backfin smaller be 2.7.
