Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: a fireproof and flame-retardant wood veneer comprises a plywood layer 1 and two surface layers 2 compounded on the upper surface and the lower surface of the plywood layer 1.
As shown in fig. 1, the plywood layer 1 includes an upper substrate layer 11, an intermediate flame-retardant board layer 12, and a lower substrate layer 13, which are sequentially laminated. The upper substrate layer 11, the middle flame-retardant board layer 12 and the lower substrate layer 13 are compounded through glue. A plurality of embedding parts 121 respectively embedded in the upper substrate layer 11 and the lower substrate layer 13 are arranged on both the upper surface and the lower surface of the middle flame-retardant sheet layer 12, and the embedding parts 121 are integrally formed on the middle flame-retardant sheet layer 12.
As shown in fig. 1 and 2, a plurality of first grooves 14 are formed on the upper surface of the upper substrate layer 11 of the plywood layer 1 and are arranged and distributed along the length direction of the plywood layer 1. A plurality of second grooves 15 are formed in the lower surface of the lower substrate layer 13 of the plywood layer 1 and arranged along the length direction of the plywood layer 1. The first grooves 14 and the second grooves 15 have the same depth. And the orthographic projection of the first groove 14 covers the space portion between the two second grooves 15 adjacent below.
As shown in fig. 1 and 2, a fireproof mesh fabric layer 16 is provided in each of the first groove 14 and the second groove 15. A fireproof paint layer 17 is coated on the upper surface of the upper substrate layer 11 except the first groove 14 and the lower surface of the lower substrate layer 13 except the second groove 15, and the thickness of the fireproof mesh fabric layer 16 is the same as the depth of the fireproof paint layer 17 combined with the depth of the first groove 14.
As shown in fig. 1 and 2, two surface layers 2 are respectively compounded on the upper substrate layer 11 and the lower substrate layer 13 by glue, and the surface layer 2 compresses the fireproof mesh fabric layer 16 after compounding.
The implementation effect is as follows: (1) a plurality of first grooves 14 and second grooves 15 are respectively formed in the upper surface and the lower surface of the plywood layer 1, the orthographic projection of each first groove 14 covers the interval part between two adjacent second grooves 15 below, and the fireproof gridding cloth layers 16 in the first grooves 14 and the second grooves 15 are staggered with each other at the moment, so that the fireproof and flame-retardant effects are guaranteed; the surface layer 2 can not be directly covered on the fireproof gridding cloth layer 16, so that the structural stability of the surface layer 2 after being compounded can be improved; meanwhile, the first groove 14 and the second groove 15 are provided with cavities, so that a certain heat preservation effect is achieved. (2) The depth of the first groove 14 is the same as that of the second groove 15, the thickness of the fireproof gridding cloth layer 16 is the same as that of the first groove 14, and at the moment, the fireproof gridding cloth layer 16 is filled in the first groove 14 and the second groove 15, so that the fireproof gridding cloth layer 16 can be compressed by the surface layer 2 when the surface layer 2 is compounded, and the fireproof gridding cloth layer 16 is fixed. (3) Because of fireproof grid cloth layer 16's fire behaviour is higher than fireproof paint layer 17's fire behaviour, but the direct structure steadiness after can leading to compounding that covers of surface course 2 on fireproof grid cloth layer 16 is relatively poor, be in first recess 14 through plywood layer 1 upper and lower two surfaces this moment, second recess 15 department has all been scribbled fireproof paint layer 17, cooperate first recess 14 again, the fireproof grid cloth layer 16 that sets up in the second recess 15, finally realize guaranteeing the structure steadiness after surface course 2 compounds under the condition that improves fireproof fire behaviour. (4) The plywood layer 1 comprises an upper substrate layer 11, a middle flame-retardant board layer 12 and a lower substrate layer 13, and the interior of the plywood can be flame-retardant through the middle flame-retardant board layer 12, so that the fireproof flame-retardant effect is improved; meanwhile, the embedding part 121 on the middle flame-retardant layer is embedded in the upper substrate layer 11 and the lower substrate layer 13, so that the structural strength of the plywood layer 1 can be improved.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
