The internal temperature preservation system comprises a substrate wall body; the inner side of the substrate wall body is sequentially provided with a first desulfurization gypsum temperature preservation mortar layer, a polyurethane inorganic composite plate, a second desulfurization gypsum temperature preservation mortar layer, a gypsum layer as well as a water-resistant putty layer arranged on the surface of the gypsum layer by shaving; and glass fiber gridding cloth is embedded into the gypsum layer. The internal temperature preservation system provided by the utility model has the beneficial effects that the system has the advantages of low heat conduction coefficient, good temperature preservation performance, water resistance and dampness resistance; the combustion performance level achieves the A-level fire-proofing requirement, and meets the A2-level relevant provisions in GB8624-2006 Building Material and Product Combustion Performance Classification.

Description

Exterior wall internal insulation system

Technical field

The utility model relates to a kind of exterior wall heat-preserving system, relates in particular to a kind of outer heat-insulation system within the walls.

Background technology

General people adopt external wall outer insulation to building usually, but not only cost is higher owing to exterior-wall heat insulation, and heat up (cooling) is slow, so be difficult to rapidly fire extinguishing when breaking out of fire.

In recent years, how architectural exterior insulation material fire occurs in succession, cause serious casualties and property loss, building inflammable, flammable heat insulating material for external has become a kind of new disaster hidden-trouble, and the fire that causes thus also has been the multiple impetus.

The utility model content

The purpose of this utility model is to solve above-mentioned technical problem, and a kind of exterior wall internal insulation system is provided.

The purpose of this utility model is achieved through the following technical solutions:

Exterior wall internal insulation system, comprise base course wall, the inboard of described base course wall is disposed with from inside to outside the first desulfurated plaster heat preservation slurry layer, polyurethane inorganic composite plate, the second desulfurated plaster heat preservation slurry layer, gypsic horizon and scrapes batch water proof putty layer that is arranged at the gypsic horizon surface, is embedded with glass fiber reticular cloth in the described gypsic horizon.

Preferably, described the first desulfurated plaster heat preservation slurry layer and the second desulfurated plaster heat preservation slurry layer thickness are at least 10mm.

Preferably, described gypsic horizon thickness is 5-8mm.

Preferably, described polyurethane inorganic composite plate comprises the polyurethane inner core and is sprayed at the fire proof heat-insulation layer of core surface.

The beneficial effects of the utility model are mainly reflected in: (1) External Wall adopts heat preservation system inside, it is low that system has a coefficient of thermal conductivity, good heat insulating, the advantage of waterproof, protection against the tide, and the combustibility rank reaches the requirement of A level fireproof, satisfies the relevant regulations of A2 level among the GB8624-2006 " constructional materials and goods classification system for fire performance ".

(2) desulfurated plaster is cementitious material, not only solved the desulfurated plaster land occupation and environment has been caused the problem of secondary pollution, and its price is lower than the plaster of paris, and its economic benefit and social benefit all are higher than the plaster of paris, are engineerings that turns waste into wealth.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Fig. 1: structural representation of the present utility model.

The specific embodiment

The utility model has disclosed a kind of exterior wall internal insulation system, and deck comprises base course wall 1 as shown in Figure 1.The inboard of described base course wall 1 is disposed with from inside to outside the first desulfurated plaster heat preservation slurry layer 2, polyurethane inorganic composite plate 3, the second desulfurated plaster heat preservation slurry layer 4, gypsic horizon 5 and scrapes batch water proof putty layer (meaning not shown in the figures) that is arranged at the gypsic horizon surface, is embedded with glass fiber reticular cloth 6 in the described gypsic horizon 5.

Concrete, described the first desulfurated plaster heat preservation slurry layer 2 and the second desulfurated plaster heat preservation slurry layer 4 are as cementing agent in the utility model, connect thickness and are approximately 10mm.Described gypsic horizon 5 thickness are 5-8mm.

Described desulfurated plaster heat preservation slurry layer is take desulfurated plaster as cementitious material, and the light materials such as perlite, glass bead, expanded vermiculite, haydite are aggregate, the inorganic heat preservation slurry formulated with multiple additives.

Described gypsic horizon is take desulfurated plaster as cementitious material, and fine sand is aggregate, and is formulated with multiple additives.

Adopt the desulfurated plaster heat preservation slurry to wrap up the polyurethane inorganic composite plate, when heat-insulation system ran into fire, the gypsum decomposes became semi-hydrated gypsum, hard burnt plaster by dihydrate gypsum, and the moisture that discharges has retarding action to fire spreading;

Because polyurethane is wrapped in the desulfurated plaster heat preservation slurry, the flue gas that the polyurethane burning discharges is sealed in the middle of the system, thereby the flue gas that discharges when reducing fire reduces the loss that fire causes;

Simultaneously, in order to improve the fire resistance of polyurethane, described polyurethane inorganic composite plate 3 is by the polyurethane inner core and all is coated with fire-proof heat-insulating material six of inner core and makes.

Below sketch lower job practices of the present utility model:

Step 1, at first to the body of wall base treatment;

Step 2, the body of wall basic unit that handles well is carried out snap the line, do ash cake, floating screed;

Step 3, stirring desulphurization gypsum insulation slurry are pasted the polyurethane inorganic composite plate take the desulfurated plaster heat preservation slurry as cementing agent, adopt completely sticking method construction, guarantee whole heat-insulation system without cavity, reserve the 10mm slit between plate and the plate;

Step 4, stirring desulphurization gypsum insulation slurry are smeared the desulfurated plaster heat preservation slurry in the polyurethane inorganic composite surface, the about 10mm of construction thickness, and fill up the plate seam;

Step 5, float coat brushing gypsum, construction thickness 5-8mm, and be pressed into glass fiber reticular cloth;

Step 6, batch scrape water proof putty;

The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
