Description
Technical field
The utility model is related to the fields of external heat preserving structure for exterior wall, and in particular to a kind of polyphenyl board exterior wall outer thermal insulation system.
Background technology
With the development of economy, people's living standard improves, and inhabitation, public building condition improve constantly, to building
The requirement of design also constantly improves, modern architecture not only to consider it is beautiful and comfortable, will also be in the same of the individual character in view of design
When, take into account environmental protection and energy-efficient design and utilization.External thermal insulation system comes into being, and is increasingly becoming building thermal-insulation energy-saving
The mainstream of form.
External thermal insulation system is mainly base course wall+bonding mortar layer+insulating layer+decorative mortar layer+finish coat, exterior wall
Outside wall heat preservation has protection agent structure, extends building life, substantially eliminates the influence of " heat bridge " and be convenient for old building
The advantages of carrying out reducing energy consumption, but still there is certain limitation in External Thermal Insulation Technology for External.The inside of insulating layer is by Indoor Temperature
Spending environment influences, and annual range of temperature variation is smaller, and the outside of insulating layer is influenced by outdoor temperature environment, annual range of temperature variation compared with
Greatly, the difference variation difference of insulating layer both sides causes entire wall body structure to deform upon, and forms the crack of building structure, at this time rain
Water or steam will enter insulating layer and bonding mortar layer along crack, and then the adhesive strength of insulating layer is caused to decline, from
And external thermal insulation structure is caused to fall off.Moreover, it when using styrofoam as external wall outer insulation material, is produced since exterior wall cracks
Raw crack, part styrofoam is exposed in air, and the fire-protection rating of styrofoam on the market is not high at present, essentially B2 grades
(flammable) and B3 grades (inflammable).Therefore when fire occurs, exposed styrofoam encounters burning things which may cause a fire disaster and will burn, and then causes
Exterior wall burning generates thick smoke, endangers the life security and health of people.
Utility model content
The utility model is intended to provide a kind of polyphenyl board exterior wall outer thermal insulation system, to solve in External Thermal Insulation System
External thermal insulation structure is caused to fall off and the problem of Fire-proof Capability of Outer-wall External Thermal difference because the adhesive strength of insulating layer reduces.
In order to achieve the above objectives, the basic technology scheme of the utility model is as follows：A kind of polyphenyl board exterior wall outer thermal insulation system,
The adhesive layer that is arranged from inside to outside successively including wall base and from the wall base, glass fiber mesh, is smeared insulating layer
Facing sand pulp layer and finish coat；The insulating layer includes several modified polyphenyl plates, and the modified polyphenyl plate is styrofoam processed
The modified polyphenyl plate that fire retardant generates is added in journey；Enhancing net is equipped between the glass fiber mesh and decorative mortar layer, it is described
Insulation putty for architectural exterior wall layer is equipped between decorative mortar layer and finish coat, the finish coat includes fireproof coating layer.
The principle of this programme is：Fire retardant is added in styrofoam process and generates modified polyphenyl plate, improves styrofoam
Fire retardant performance, and then improve external thermal insulation system fire-protection rating.When practical application, applied in wall base first
It covers bonding agent and forms adhesive layer, modified polyphenyl plate is secondly bonded in formation modified polyphenyl plate insulating layer in wall base,
Then glass fiber mesh is covered on modified polyphenyl plate insulating layer, then will enhancing net to be covered in glass fibre online, utilize anchor
Gu glass fiber mesh and enhancing net are fixed on modified polyphenyl plate insulating layer by nail, modified polyphenyl plate insulating layer is further fixed,
It is avoided to fall off from wall base.Then, in the online coating decorative mortar layer of enhancing, exterior wall guarantor is coated outside decorative mortar layer
Warm putty layer.Since insulation putty for architectural exterior wall layer has the function of heat-insulation and heat-preservation, ambient temperature can be reduced to wall
The influence of structure so that the difference variations of insulating layer both sides reduces, and then reduces the cracking of wall body structure, to avoid steam into
Entering modified polyphenyl plate insulating layer and adhesive layer causes modified polyphenyl plate insulating layer to be detached from wall base because bonding force reduces, with
And avoid modified polyphenyl plate insulating layer exposed in air.Finally, the decorations such as fireproof coating layer are coated outside insulation putty for architectural exterior wall layer
Face layer, coating fireproof coating layer can effectively avoid occurring the sprawling of intensity of a fire when fire.
The advantages of this programme is：1, styrofoam is modified, improves its fire protecting performance, avoid the exterior wall when fire occurs
Outer heat preservation system encourages fire spreading, threatens the life security of people.2, common using glass fiber mesh and enhancing net Double-level Reticulated
Fixed modified polyphenyl plate insulating layer, is further ensured that modified polyphenyl plate insulating layer will not be fallen off easily.3, in decorative mortar
It is equipped with exterior insulation putty layer between layer and finish coat, reduces influence of the ambient temperature to wall body structure, reduces wall
The cracking of structure, avoiding rainwater or steam from entering wall body structure internal layer causes modified polyphenyl plate insulating layer to fall off, and avoids
Modified polyphenyl plate is exposed in air.4, finish coat includes fireproof coating layer, further improves external thermal insulation system
Fire protecting performance.
Preferably, as an improvement, the additive amount of the fire retardant accounts for the 4%~8% of styrofoam quality.
When the additive amount of fire retardant accounts for 4% or less styrofoam quality, the fire protecting performance of the modified polyphenyl plate of generation is paid no attention to
Think；When the additive amount of fire retardant accounts for 8% or more of styrofoam quality, the fire protecting performance of the modified polyphenyl plate of generation is no longer carried
It rises.Therefore, the additive amount of fire retardant accounts for the 4%~8% of styrofoam quality more preferably to select.
Preferably, as an improvement, the modified polyphenyl plate surface is coated with one layer of fire protection flame retarding layer.
The fire protecting performance for improving modified polyphenyl plate, further increases the fire protecting performance of external thermal insulation system.
Preferably, as an improvement, the enhancing net is that galvanizing is welded steel wire.
Galvanizing be welded steel wire have excellent anticorrosive property, solder joint is secured, mesh is uniform, local mechanical processing performance
The advantages that good.
Preferably, as an improvement, bonding agent used in the adhesive layer is QH-101 styrofoam bonding agents.
Compared to other bonding agents, QH-101 styrofoam bonding agents have more excellent adhesive property, and with excellent
Sagging resistance and water-retaining property.
Preferably, as an improvement, decorative mortar used in the decorative mortar layer is QH-102 protective facing sand
Slurry.
Compared to other decorative mortars, QH-102 protective facing mortars have very excellent elasticity and adhesive property, and
And have the advantages that shock resistance, ageing-resistant, water resistance is high, nontoxic, odorless and non-ignitable.
