Abstract

The utility model relates to a multifunctional light composite board, which is used for new buildings. An upper and a lower surface layers adopt rigid fire-proof boards with metal or non-metal materials; core materials adopt inorganic cellucotton or other thermal insulation fire-proof materials. The core materials are bonded between the upper and the lower surface layers by binding agents, and an integral body is formed; the binding agents adopt polyurethanes binding agents. The utility model has the advantages that mechanical favorable mechanical properties, and favorable properties of thermal insulation, sound absorption and fire prevention. The utility model can be widely used for the new buildings.

Description

The multifunctional light composite plate

The utility model is a kind of multifunctional light composite plate, belongs to the New Building Materials field.

The existing light composite board that puts goods on the market, it is that color painted steel strip, core are that the polyphenyl battenboard and the core of polyphenyl foam plate is the polyurethane laminboard of hard polyurethane foam plate that surface layer is arranged, the shortcoming of this kind sheet material is that fire protecting performance is poor, intensity is also poor, especially under high temperature and thunderbolt situation, the very fast contraction of the core of plate, distortion lose intensity so that catch fire.

The purpose of this utility model is the weak point at above-mentioned existing several light composite boards, according to of the requirement of novel building industry to the composite board serviceability, manufacture and design a kind of material that has certain intensity with heatproof, lightweight and make core, with metal or nonmetal rigidity fire-proof board multifunctional light composite plate, to be applicable to roof of buildings and materials for walls such as industrial premises, garage, combined padding and drying system, computer floor as surface layer.

The technical solution of the utility model as shown in Figure 1, as surface layer 1, cotton or other insulated fire light material is as core 3 with inorfil with metal or nonmetallic rigidity fire-proof board, with polyurethane adhesive as adhesive layer 2.Surface material can be used color painted steel strip, zinc-plated roll bending, black sheet plate, Thistle board, cement pressure plare, GRC plate etc.; Core 3 can be used rock wool, mineral wool, mineral wool, honeycomb paper etc., and binding agent is with the polyurethane adhesive of one-component or two components.According to instructions for use; Upper and lower surface layer 1 can be used same material, also can be with same material not, and as the one side color painted steel strip, another side is with plasterboard or GRC plate cement pressure plare etc.

The utility model and correlation technique its advantage of comparison and effect are as follows:

1. this slate cotton fiber is upright to stressed, so it has higher mechanical property, and rock wool fibers has toughness, can well resist reloading.

This plate thermal resistance R be 1.72mk/w (2.0m.h ℃/kcal); Coefficient K is 588w/m ²K (0.48kcal/m ².h. ℃), be equivalent to following traditional exterior wall heat transfer property in winter, a, the body of wall of wiping one's face inside and outside three bricks; B, a brick false add 25mm foamed brick wood-fibred adds rendering layer; C, 600 unit weight aerated blocks 300mm wipe one's face the thick both sides that add.

3. its fire protecting performance, the plate that 80mm is thick, the structure fire resistance limit can reach more than 2 hours, was far superior to polyphenyl battenboard (75 ℃ of decomposition) and polyurethane foam composite plate (132.5 ℃ of decomposition).

4. rock wool is a kind of efficient sound-absorbing material, so this plate has acoustical behavior preferably.

Therefore, the utility model is not only a kind of multi-use architecture parts, a kind of especially fire prevention energy-saving material, it can be widely used in big-and-middle-sized industrial premises, hangar, garage, computer floor, commercial scenery travelling point architecture, assembled house, office etc., because it has lightweight characteristics, also be suitable for overbuilding story, go along with sb. to guard him cutting apart between wholly etc.

Accompanying drawing 2,3,4,5,6,7 is embodiment of the present utility model.

Embodiment 1 (Fig. 2,3) if the light composite board desired strength is good, indeformable, will cut into inch strips perpendicular to the rock wool fibers direction as the rock wool of core 3, with rock cotton sliver 7 stand up make rock wool fibers perpendicular to surface layer, rock cotton sliver arrange be positioned over upper and lower two-layer between, be bonded on the upper and lower surface layer with polyurethane adhesive, this kind composite plate structure, fiber are vertically stressed, the intensity height, composite plate can not be compressed distortion, can be used as structural member and uses.

Embodiment 2 (Fig. 4,5) if light composite board is only made warming plate, can be tiled in the rock cotton board monoblock between the upper and lower faces layer, is bonded on two surface layers with binding agent.

Embodiment 3 (Fig. 6) is if light composite board as building wall board usefulness, can need to use on the color painted steel strip according to decorating, roll compacting goes out decorative stripe 4 on rolling mill, plate width both sides are pressed into the connection termination 5 of requirement, so that when installing, peg graft mutually or overlap joint with the polylith composite plate.

Embodiment 4 (Fig. 7), if light composite board as building top board usefulness, roll compacting has decorative stripe 4 on the following surface layer color painted steel strip, roll compacting has the reinforcement 6 of trapezoidal cross-section on the upper layer color painted steel strip; Also fill up core in the trapezoidal cross-section, reinforcement can be strengthened the rigidity of building top board.
