Description

Technical Field

[0001] The utility model relates to the technical field of PVC foam boards, in particular to a fireproof PVC foam board. Background Art

[0002] PVC foam board is also called Chevron board and Andy board. Its chemical composition is polyvinyl chloride, so it is also called foam polyvinyl chloride board. It is widely used in interior decoration boards, building exterior wall boards and interior decoration boards. PVC foam board is easily affected by the environment during use and has poor fire resistance. It is easy to spontaneously combust due to high temperature in extreme environments, which makes the fireproof effect of the foam board poor. It is also easy to be affected by moisture. Over time, it is easy to absorb moisture and mildew, which makes the waterproof effect of the foam board poor, affecting the service life of the foam board. Utility Model Content

[0003] In view of this, the utility model provides a fireproof PVC foam board, which can take into account the waterproof, moisture-proof and fireproof functions of the PVC foam board, extend its service life, and improve the waterproof and fireproof effects of the PVC foam board.

[0004] The technical solution is: a fireproof PVC foam board, including a PVC foam board, a fixed layer, dehumidification holes, dehumidification cotton, a fireproof layer, a support plate, a waterproof layer and a wear-resistant layer. Fixed layers are arranged on both sides of the PVC foam board, and the two fixed layers are symmetrically arranged. A plurality of dehumidification holes are opened on the two fixed layers. The plurality of dehumidification holes located on the same fixed layer form a group, and dehumidification cotton is arranged in a ring shape in each of the plurality of dehumidification holes. A fireproof layer is arranged on the side of the two fixed layers away from each other, a support plate is arranged on the side of the two fireproof layers away from each other, a waterproof layer is arranged on the side of the two support plates away from each other, and a wear-resistant layer is arranged on the side of the two waterproof layers away from each other.

[0005] Furthermore, the two fixing layers are both polyester sheets.

[0006] Furthermore, both fireproof layers are made of aluminum oxide.

[0007] Furthermore, both waterproof layers use nano-penetrating high-efficiency waterproofing agent.

[0008] Furthermore, both wear-resistant layers are made of ceramic particles.

[0009] The beneficial effects are as follows: in the utility model, dehumidification is performed through a plurality of dehumidification holes on the two fixed layers, so that the foam board is drier when in use, and the two waterproof layers can make the foam board have better waterproof and moisture-proof functions, and at the same time, the two fireproof layers can make the foam board have better fireproof effect, thereby extending its service life and improving the waterproof and fireproof effects of the PVC foam board.

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] Embodiment 1: A fireproof PVC foam board, such as Figure 1-Figure 2 As shown, it includes a PVC foam board, a fixed layer, dehumidification holes, dehumidification cotton, a fireproof layer, a support plate, a waterproof layer and a wear-resistant layer. The fixed layers are fixedly connected on both sides of the PVC foam board, and the two fixed layers are symmetrically arranged. A plurality of dehumidification holes are opened on the two fixed layers. The plurality of dehumidification holes located on the same fixed layer form a group, and a plurality of dehumidification holes in each group are provided with dehumidification cotton. The plurality of dehumidification cottons are arranged in a ring shape. The fireproof layer is fixedly connected on the sides of the two fixed layers away from each other, the support plates are arranged on the sides of the two fireproof layers away from each other, the waterproof layer is arranged on the sides of the two support plates away from each other, and the wear-resistant layer is arranged on the sides of the two waterproof layers away from each other.

[0015] Furthermore, the two fixing layers are both polyester sheets.

[0016] Furthermore, both fireproof layers are made of aluminum oxide.

[0017] Furthermore, both waterproof layers use nano-penetrating high-efficiency waterproofing agent.

[0018] Furthermore, both wear-resistant layers are made of ceramic particles.

[0019] In the utility model, dehumidification is performed through a plurality of dehumidification holes on the two fixed layers, and dehumidification cottons are connected to the dehumidification holes. The plurality of dehumidification cottons absorb moisture on the foam board, so that the foam board is drier when in use. The two waterproof layers can make the foam board have better waterproof and moisture-proof functions, and the foam board can be prevented from absorbing moisture and mildewing in a humid air environment as much as possible. At the same time, the two fireproof layers can make the foam board have better fireproof effect, and the foam board can be prevented from spontaneous combustion due to excessive temperature as much as possible, so that the fireproof effect of the foam board is better when in use, the service life of the foam board is extended, and the waterproof and fireproof effects of the PVC foam board are improved.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
