The utility model is characterized in that the polyethylene foam thermal insulation system comprises a bonding mortar layer, a polyethylene foam layer, an anti-crack mortar layer and a decoration layer from inside to outside, wherein a basic layer is taken as the bottom; the bonding mortar layer and the polyethylene foam layer are fixed on the basic layer by anchor bolts; and the polyethylene foam layer is a blind-hole type flame-retardant organic foam plastic plate. The utility model provides the thermal insulation system containing organic porous flexible elastic material, has the obvious advantages of good sound insulation, light weight and good fire prevention, thermal insulation, moisture protection, watertightness and chemical corrosion, can only cause micro-deformation at the temperature of minus 45 to 70 DEG C and can not cause pollution to environment.
Description
Technical field
The utility model belongs to building field, is specifically related to a kind of polyethylene heat-insulation system of external wall.
Background technology
Existing is on the body of wall of needs insulation, asbestos, glass wool or foamed plastics to be installed to the adiabatic method of building heat preserving.Inorganic heat insulation material such as asbestos, glass wool is prone to suction, and suction back heat insulation effect variation loses energy-conservation meaning, and mouldy easily, breed bacteria.Expansion polyphenyl plate (EPS) easy of crack greatly reduces application life of material; Coefficient of thermal conductivity is higher, and along with the raising of energy conservation standard, its insulation layer is thicker.Extruded polystyrene board (XPS) excellent thermal insulation performance, but easy deformation.And all there is the problem of fireproof performance difference in which kind of polyphenyl plate, and burning velocity is fast and discharge a large amount of black smokes during burning.
Summary of the invention
The purpose of the utility model is, overcomes the deficiency of existing building external-wall heat-insulation material, and the polyethylene heat-insulation system of a kind of fire prevention, protection against the tide, safety and environmental protection, durable, the convenient and practical external wall with insulation heat-insulating property is provided.
The polyethylene heat-insulation system of external wall; It is characterized in that comprising with the basic unit is the outer structure layer by the lining at the end: adhesive mortar layer, polyethylene layer, anticracking grout layer and finish coat; Said adhesive mortar layer, polyethylene layer are fixed in the basic unit through crab-bolt, and said polyethylene layer is the fire-retardant organic foam plastic plate of closed pore formula.
Also has alkali-resistant glass fibre grid layer of cloth between said anticracking grout layer and the finish coat.
Said polyethylene layer thickness is 20mm～50mm.
Said polyethylene layer is bonded together by many slim polyethylene foam sheets.
The material of said finish coat is a polymer mortar.
Its coefficient of thermal conductivity is 0.030W/mk～0.037W/mk, and density is: 18kg/m
3～50kg/m
3
The utility model is applied to polyethylene foam sheet the heat-insulation system of external wall; Because the polyethylene layer is the fire-retardant organic foam plastic plate of closed pore formula; The fire-retardant organic foam plastic plate of existing closed pore formula is processed after foaming by polyvinyl, blowing agent, crosslinking agent, dispersing agent, sliding agent, fire retardant, Masterbatch component; From putting out, exhaust gas volumn is few from fire, and water absorption rate is no more than 0.05%.Its high insulating effect, good flame resistance, fire prevention, protection against the tide, convenient and practical.
Between anticracking grout layer and finish coat, be added with the alkali resistant glass fibre open weave cloth layer, make finish coat be not easy cracking, increase pulling force each other.
The advantage of the utility model is: a kind of heat-insulation system that contains the gentle elastomeric material of organic porous is provided; It has many outstanding advantages; Like sound insulation, light weight, fire prevention, thermal insulation, moistureproof and waterproof, resistance to chemical attack; Under-45 degrees centigrade～70 degrees centigrade, micro-strain only occurs, can not pollute environment.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model:
Each label is listed as follows among the figure:

The specific embodiment
Shown in 1 figure; The polyethylene heat-insulation system of the utility model external wall; Comprise with basic unit 1 being the outer structure layer by the lining at the end: adhesive mortar layer 2, polyethylene layer 3, anticracking grout layer 5, alkali-resistant glass fibre grid layer of cloth 6 and finish coat 7; Said adhesive mortar layer 2, polyethylene layer 3 are fixed in the basic unit 1 through crab-bolt 4, and said polyethylene layer 3 is the fire-retardant organic foam plastic plate of closed pore formula.The fire-retardant organic foam plastic plate of existing polyvinyl closed pore formula is processed after foaming by polyvinyl, blowing agent, crosslinking agent, dispersing agent, sliding agent, fire retardant, Masterbatch component, and from putting out, exhaust gas volumn is few from fire, and water absorption rate is no more than 0.05%.Its high insulating effect, good flame resistance, fire prevention, protection against the tide, convenient and practical.
The fire-retardant organic foam plastic plate of polyvinyl closed pore formula has commercially available, and in the present embodiment, the mass fraction of the blowing agent in the foaming component of employing is between 10～20 parts, and the density of this plate is at 20～50kg/m
3Between.
The fire-retardant organic foam plastic plate of this polyvinyl closed pore formula is to have certain thickness rectangular flat or square flat board, and it is 20mm～50mm that the heating laminating type that passes through is made into thickness, and can be used for being attached at needs the container or the external wall of insulation to make insulation layer.
The job practices of the polyethylene heat-insulation system of external wall comprises following step:
A. do leveling layer intending plastering on the body of wall will do insulation layer, the metope after the levelling should keep clean;
B. use the special bonding mortar that said building exterior wall heat preserving plate is bonded on the leveling layer;
C. use crab-bolt that the building exterior wall heat preserving plate is fixed;
D. the seam of the junction plate between every block of building exterior wall heat preserving plate is done encapsulation process;
E. do the anticracking grout leveling layer in the outside of building exterior wall heat preserving plate, and compound alkali-resistant glass fibre grid cloth;
F. cover glass fiber reticular cloth and do facing with polymer mortar.
The advantage of the utility model is: a kind of heat-insulation system that contains the gentle elastomeric material of organic porous is provided; It has many outstanding advantages; Like sound insulation, light weight, fire prevention, thermal insulation, moistureproof and waterproof, resistance to chemical attack; Under-45 degrees centigrade～70 degrees centigrade, micro-strain only occurs, can not pollute environment.
