Technical Field

The utility model relates to a fire floor technical field, concretely relates to OSB fire floor.

Background

Oriented strand board (OSB board) is recognized as one of the most developed, organically and technically mature panels. The OSB board is made up of soft needle, small diameter wood of broad leaf tree, fast growing intermediate cut wood, etc. such as eucalyptus, fir, poplar intermediate cut wood, etc. through drying, gluing, directional spreading and hot pressing. The fireproof performance and the sound insulation performance of the floor manufactured by the OSB board are slightly insufficient at present. Particularly, the OSB fireproof floor has high use value in places with high fireproof performance, such as hotels, KTVs and the like.

An OSB fireproof floor comprises an OSB substrate layer, a sound insulation layer, a first fireproof layer, a second fireproof layer, a finishing layer and a fireproof coating layer which are sequentially arranged from bottom to top;

the thickness of the OSB substrate layer is 15-18mm, and two sides of the OSB substrate layer are respectively provided with a semi-cylindrical concave part and a semi-cylindrical convex part;

the sound insulation layer is a polyester fiber sound absorption plate, a plurality of groups of cylindrical hollow holes are arranged on the polyester fiber sound absorption plate in a penetrating mode, and the thickness of the polyester fiber sound absorption plate is 2-4 mm;

the first fireproof layer is a magnesium chloride fireproof layer, the thickness of the magnesium chloride fireproof layer is 1-2mm, the second fireproof layer is an asbestos plate, and the thickness of the asbestos plate is 2-3 mm;

the decorative layer is a melamine impregnated bond paper decorative artificial board, the thickness of the melamine impregnated bond paper decorative artificial board is 2-3mm, and the thickness of the fireproof coating layer is 1-2 mm.

The fireproof coating layer is made of transparent fireproof coating.

And the OSB substrate layers of two adjacent OSB fireproof floors are mutually clamped through the concave parts and the convex parts.

Detailed Description

As shown in the attached drawings, the OSB fireproof floor comprises an OSB substrate layer 1, a sound insulation layer 2, a first fireproof layer 3, a second fireproof layer 4, a decorative layer 5 and a fireproof coating layer 6 which are sequentially arranged from bottom to top;

the thickness of the OSB substrate layer 1 is 15-18mm, and two sides of the OSB substrate layer 1 are respectively provided with a semi-cylindrical concave part 8 and a convex part 9;

the sound insulation layer 2 is a polyester fiber sound absorption plate, a plurality of groups of cylindrical hollow holes 7 are arranged on the polyester fiber sound absorption plate in a penetrating mode, and the thickness of the polyester fiber sound absorption plate is 2-4 mm;

the first fireproof layer 3 is a magnesium chloride fireproof layer, the thickness of the magnesium chloride fireproof layer is 1-2mm, the second fireproof layer 4 is an asbestos plate, and the thickness of the asbestos plate is 2-3 mm;

the decorative layer 5 is a melamine impregnated bond paper decorative artificial board, the thickness of the melamine impregnated bond paper decorative artificial board is 2-3mm, and the thickness of the fireproof coating layer 6 is 1-2 mm.

The fireproof coating layer 6 is made of transparent fireproof coating, and the decorative effect of the decorative layer cannot be damaged.

OSB substrate layers 1 of two adjacent OSB fireproof floors are mutually clamped through the concave parts 8 and the convex parts 9, so that the bottom plates can be conveniently spliced.

The OSB substrate layer 1, the sound insulation layer 2, the first fireproof layer 3, the second fireproof layer 4, the decorative layer 5 and the fireproof coating layer 6 are bonded with one another through environment-friendly adhesives, and zero emission of formaldehyde is achieved.

The aperture of the cylindrical hollow hole 7 is 2-4mm, so that sound insulation is effectively realized.

The working principle is as follows: the OSB substrate layer 1 is sequentially bonded with a polyester fiber sound-absorbing board, a magnesium chloride fireproof layer, an asbestos board and a melamine impregnated bond paper veneer artificial board through an environment-friendly adhesive, and a transparent fireproof coating is coated on the melamine impregnated bond paper veneer artificial board; multilayer flame retardant coating sets up the transparent fire retardant coating of cooperation, and effective fire-retardant fire prevention bonds through the environmental protection gluing agent between each layer and is in the same place, realizes the formaldehyde zero release, and the floor sound insulation effect is good simultaneously, and especially adapted application has use value in places such as the hotel or KTV that fire prevention sound insulation performance required height.
