Description

Plastic building board

The invention relates to a plastic building board, in particular to a plastic wave board used for a roof or a plastic wall board used for a wall. In order to increase the bonding between the plastic building boards, there is no peeling and weather resistance.

According to the traditional roof, the wave board or the wall used for the wall is usually made of plastic material, or made of glazed plastic. The plastic wave board is usually used on the outdoor roof or plastic wall for the wall. Weatherability and long-term use are not ideal. Therefore, after the long-term exposure of the plastic wave board or the plastic siding to the sun and the rain, the plastic wave board or the plastic siding is prone to damage and water seepage, and the service life is poor, and actually has a great improvement space.
Generally, the industry often uses a plastic wave board 1 composed of a roof and three layers combined with each other. A PU foaming intermediate layer 13 is disposed between an upper layer 11 and a lower layer 12 of the plastic wave board 1, see the first As shown in the figure, the plastic wave board 1 is bonded to the upper board layer 11 and the lower board layer 12 by the adhesiveness of the PU foaming intermediate layer 13 itself. However, although the plastic wave plate 1 formed by bonding three layers to each other has a relatively thick thickness, and the adhesiveness seems to be feasible at first glance, the adhesion is very difficult to control after long-term use, and this is also the three-layer plastic. The PU foaming intermediate layer 13 of the wave plate 1 and the bonding portion 14 between the upper plate layer 11 and the lower plate layer 12 are respectively subjected to the sun and strong wind, so that the plastic wave plate 1 and the upper plate layer 11 and the lower plate layer 12 are respectively Peeling is likely to occur, resulting in poor bonding between the plastic wave plates.

The invention solves the technical problem that the plastic material is improved in the adhesiveness of the plastic wave board, and the weather resistance and the service life are not ideal. The invention provides the plastic wave board used for the roof or the plastic wall board used for the wall. In order to strengthen the combination of plastic building panels, there will be no peeling, and plastic building panels with increased heat resistance temperature, weather resistance and long service life.
For the purpose of the foregoing invention, the technical solution adopted by the present invention is to provide a plastic building board comprising a plastic inner layer, a plastic foam layer disposed above the inner layer of the plastic, and a plastic layer disposed on the plastic a plastic outer layer above the foam layer and more weather resistant than the inner layer of the plastic, the material between the plastic foam layer and the inner layer of the plastic is melted to form a first fusion layer, and the material between the plastic foam layer and the outer layer of the plastic is melted Forming a second fusion layer, passing through the first fusion layer and the second fusion layer, the intermediate plastic foam layer is more tightly bonded to the inner plastic layer and the plastic outer layer, and no peeling occurs therebetween, and the outer layer of the plastic can be utilized. Heat resistance makes plastic building panels increase their heat resistance temperature, weather resistance and service life.
The outer layer of the plastic has a thickness of 0.1 to 0.15 mm, the inner layer of the plastic has a thickness of 0.2 to 0.3 mm, and the thickness of the plastic foam layer is 2 to 3 mm, so that the total thickness of the thin plastic sheet is formed. The plastic wave board has the same thickness.
The outer layer of the plastic is made of ASA resin, and the ASA resin is made of copolymerization of styrene, acrylonitrile and acrylic rubber. Technically, ASA resin not only maintains the main characteristics of ABS plastic heat and impact resistance, but also combines the advantages of acrylic UV protection and weather resistance, so that the plastic wave board of the plastic building board of the invention can be used for outdoor roof use or Plastic panels are available for walls.
The inner layer of the plastic is made of PVC or PC plastic material, so as to maintain the advantages of light weight and good extensibility of the plastic material.
The plastic foam layer in the middle of the plastic building board is made of PVC or PE or PP or PC and a foaming agent.
By the plastic building board of the invention, the main effects can be as follows:
The plastic building board of the present invention is formed by melting a material between the plastic inner layer and the outer layer of the plastic to form a first fusion layer and a second fusion layer, and the first and second fusion layers are added to the middle. The plastic foam layer is tightly bonded to the inner layer of the plastic and the outer layer of the plastic, and no peeling occurs therebetween.
The plastic building board of the invention is disposed above the inner layer of the plastic and has a longer service life than the plastic outer layer of the plastic inner layer, so that the plastic building board has high heat resistance, impact resistance, weather resistance, and ultraviolet protection function. Provides excellent usability.

The purpose, technical contents, features and effects achieved by the present invention will become more apparent from the detailed description of the embodiments.
Referring to Figures 2-1 and 2-2, the plastic building board of the present invention refers to a thin plastic wave board 2 generally used for roofing, or a thin plastic panel used for walls as shown in Fig. 4. 4. The plastic building board comprises a plastic inner layer 21, a plastic foam layer 23 disposed above the plastic inner layer 21, and a plastic foam layer 23 disposed above the plastic inner layer 21 and weather resistant. The plastic outer layer 22, the material between the intermediate plastic foam layer 23 and the inner plastic layer 21 is melted to form a first fusion layer 24, and the material between the intermediate plastic foam layer 23 and the plastic outer layer 22 is melted to form a Second fusion layer 25.
In the embodiment of the present invention, the plastic outer layer 22 of the plastic building board has a thickness of 0.1 to 0.15 mm, the plastic inner layer 21 has a thickness of 0.2 to 0.3 mm, and the plastic foam layer 23 has a thickness of 2 to 3 mm. The total thickness of the plastic building panels forming the thin layer is the same as the thickness of the general plastic wave board.
