Description

The external heat insulating wall of the inorganic modified foam heat-insulating board of mechanically-anchored grid reinforcing rib

Affiliated technical field

The utility model relates to the thermal-insulative external wall body of the inorganic modified foam heat-insulating board of a kind of mechanical fastening system anchored grid reinforcing rib, is particularly useful for the reducing energy consumption engineering of existing building exterior wall.

Background technology

Existing inorganic modified foam heat-insulating board external heat insulating wall is the combined wall being combined as base course wall and inorganic modified foam heat-insulating board by skin, and inorganic modified foam heat-insulating board is to stick with glue agent to be fixed on base course wall as insulation layer.This structure requires to bear outer heat preservation system whole load by bonding adhesive, whole load is delivered on base course wall by body of wall leveling layer simultaneously again.But, because the warming plate that the out-of-flatness of construction wall basic unit or heat preservation plate material causes is empty sticky, leave the hidden danger of quality and security and stability may to whole external heat insulating wall.In addition, when existing building exterior wall is carried out to outer heat preservation energy-saving transformation, loose, the hollowing of the local decorative structure layer of old basic unit, cracking and the defect in various degree such as surface contaminants, barrier film, directly newly-increased stability and the safety in utilization of pasting external thermal insulation of impact.Therefore, be necessary to improve the fixing means of the inorganic modified foam heat-insulating board of wall face.

In addition, existing inorganic modified foam heat-insulating board is base material organic foam warming plate after foaming by molding machine die compression set type, then adopts inorganic fireproof material to carry out polymerization, cured modified processing forms.For example, in July, 2009 " the building fire protection material handbook " write by Zhu Chunling, Ji Guangqi of the 1st edition, Beijing that Chemical Industry Press publishes disclose: existing multiple technologies can be given high polymer material fire resistance now, they be respectively add fire retardant, add inorganic filler, with the blend of high flame retardancy high polymer material, grafting, be cross-linked and synthetic self-extinguishment high polymer etc.; The common fusing point of inorganic filler is higher, with respect to burning, it is inertia, be filled in a large number in high polymer, also can effectively improve the flame-retarding characteristic of base material, can also reduce the cost of goods simultaneously, the same with inorganic combustion inhibitor, these fillers also need to carry out surface modification, to improve the compatibility (referring to the 22nd page of inverse 11st～footline) of itself and resin; When the high polymer that contains this based flame retardant is heated, surface can generate the carbonaceous froth bed of one deck even compact, can effectively completely cut off heat and oxygen, suppresses to be fuming, and can prevent that molten drop from producing, thereby there is good fire resistance (referring to the 34th page of inverse 9th～7 row); It is fire-retardant that current fire retardant polystyrene also can add the inorganic hydrates such as aluminium hydroxide, magnesium hydroxide to carry out, and they,, except playing the effect that reduces product cost, can also eliminate its phenomenon of glowing (referring to the 186th page of inverse 8th～4 row); The method of preparing flame retardant polyurethane material mainly contains adds various additive flame retardants or inorganic filler; To polyurethane material, carry out structurally-modified, use polyalcohol or isocyanates with ignition-proof element to synthesize flame-retardant polyurethane as raw material, isocyanurate structure is incorporated in polyurethane molecular chain, thereby the charing tendency that just can improve material reduces its combustibility (referring to the 249th page of 26th～29 row); Adopt the partly or entirely organic combustible filler in substituted phenolic resin of inorganic inert filler, also can improve the fire resistance (referring to the 301st page of inverse 2nd～footline) of goods.

Because the feature of inorganic modified foam heat-insulating board is that density, coefficient of thermal conductivity and combustibility are more satisfactory, but tensile strength, flexural strength and rupture strength are lower, easily produce cracking, distortion, shrink, while being used for the body of wall of mechanical anchor heat-insulation plate for external, the inorganic modified foam heat-insulating board that existence is fixed by anchoring enbrittles, problem and the shortcoming of easy fracture.Therefore, need the structure of inorganic modified foam heat-insulating board to be improved simultaneously.
