Abstract

The utility model discloses a novel light heat insulation fireproof wallboard, which comprises steel wires 1, steel wire meshes 2, expanded perlite 3, cement mortar layers 4 and foamed cement 5. The cement mortar layers 4 are arranged on two surfaces of the novel light heat insulation fireproof wallboard 6; the steel wire meshes 2 are arranged in the middles of the cement mortar layers 4; the steel wires 1 for connection are arranged between the two steel wire meshes 2; and a composite heat insulator formed by gluing the foamed cement 5 with the expanded perlite 3 is sandwiched between the two cement mortar layers 4. By the aid of the composite heat insulator formed by gluing the foamed cement with the expanded perlite, the problem of fire protection of a thin plastered outer wall heat insulation system for an EPS (expanded polystyrene) board is solved, a traditional brick wall is replaced, the weight of a building is reduced, and the novel light heat insulation fireproof wallboard has the advantages of non-toxicity, odorlessness, non-flammability, corrosion resistance, acid-base resistance, sound insulation, heat insulation and low cost.

Description

Novel light insulated fire wallboard

(1) technical field

The utility model relates to a kind of novel light insulated fire wallboard, specifically relates to a kind of building inside and outside wall energy-saving heat preserving fire-retardant wall plate, and a lot of aspects can substitute EPS polyphenyl plate thin plastering exterior wall heat-insulation system, reach flameproof effect.

(2) background technology

In the large-scale application building energy-saving heat-insulating material, mainly contain expanded polystyrene foams (EPS), extruded polystyrene foam (XPS), polyurethane foam products such as (PU).At present, the market share, what accounting was maximum is styrofoam (containing EPS, XPS), is about 80%, and urethane accounts for 10%, and other type materials are about 10%.In fact, EPS, XPS, PU belong to organic insulation material, and great advantage is that light weight, insulation and thermal insulation are good, and greatest drawback is that fire savety is poor, and easily aging, easy firing produce a large amount of smog when burning, and toxicity is very big.EPS polyphenyl plate thin plastering exterior wall heat-insulation system bans use of in more than 20 state of the U.S. owing to relate to serious fire safety problem; In Britain, the buildings more than 18 meters does not allow to use; In Germany, the buildings more than 22 meters does not allow to use.In Europe, a lot of Insurance Company forbid accepting insurance to the building that adopts EPS to do insulation.Yet, in but large-scale promotion use of China EPS.

(3) summary of the invention

The purpose of this utility model is to have overcome the deficiencies in the prior art, and a kind of light thermal-insulation fire-retardant wall plate is provided, and can substitute EPS polyphenyl plate thin plastering exterior wall heat-insulation system and substitute traditional brick wall.

For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: the utility model light thermal-insulation fire-retardant wall plate is made up of steel wire 1, woven wire 2, pearlstone 3, cement mortar layer 4, foam cement 5.On novel light insulated fire wallboard 6 two sides cement mortar layer 4 is arranged, woven wire 2 places the centre of cement mortar layer 4, have steel wire 1 to connect between two woven wires 2, the cement mortar layer 4 on two sides clips the complex heat-preservation body that foam cement 5 glued pearlstones 3 form.

Compared with prior art, the beneficial effects of the utility model are: solved EPS polyphenyl plate thin plastering exterior wall heat-insulation system fire safety problem, substituted traditional brick wall, alleviated buildings weight, have nontoxic, tasteless, do not fire, be stale-proof, the advantage at the bottom of the acid and alkali-resistance, sound-insulating and heat-insulating, cost.The thermal conductivity of foam cement is 0.06-0.28W/ (M.K).The thermal conductivity of pearlstone is 0.055W/ (M.K).Thermal conductivity of the present utility model is at 0.06-0.10W/ (M.K).

Fig. 1 is this novel light insulated fire panel structure synoptic diagram: 1. steel wires among the figure; 2. woven wire; 3. pearlstone; 4. cement mortar layer; 5. foam cement; 6. novel light insulated fire wallboard.

(5) specific implementation method

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: Fig. 1 is this novel light insulated fire wallboard, is made up of steel wire 1, woven wire 2, pearlstone 3, cement mortar layer 4, foam cement 5.On the two sides of light thermal-insulation fire-retardant wall plate 6 cement mortar layer 4 is arranged, woven wire 2 places the centre of cement mortar layer 4, between two woven wires 2, there is steel wire 1 to connect, between two-layer cement mortar layer 4, clips the complex heat-preservation body that foam cement 5 glued pearlstones 3 form.

Claims

1. novel light insulated fire wallboard, its structure comprises steel wire (1), woven wire (2), pearlstone (3), cement mortar layer (4), foam cement (5) composition, it is characterized in that: cement mortar layer (4) is arranged on the two sides of novel light insulated fire wallboard (6), woven wire (2) places the centre of cement mortar layer (4), between two woven wires (2), there is steel wire (1) to connect, between two-layer cement mortar layer (4), accompanies the complex heat-preservation body that the glued pearlstone of foam cement (5) (3) forms.
