Description

Double wave board

The invention relates to a wave board, in particular to a double-layer wave board used for roofing in order to increase its weather resistance.

According to the traditional roof, the wave board is usually made of plastic material, or made of glazed tile plastic. However, the plastic wave board is usually on the outdoor roof, and its weather resistance and long-term use are not ideal. Therefore, after the long-term exposure of the plastic wave board to the sun and the rain, the plastic wave board is prone to damage and water seepage, and the service life is poor, and actually there is a great room for improvement.

The invention solves the technical problem of improving the weather resistance and the poor service life of the plastic wave board made of plastic material. The invention provides the double-layer wave board which strengthens the heat-resistant temperature of the double-layer wave board to increase the weather resistance and the service life.

For the purpose of the foregoing invention, the technical solution adopted by the present invention is to provide a double-layer wave board, which comprises a plastic wave inner layer and a weatherproof layer disposed on the inner layer of the plastic wave board and opposite to the inner layer of the plastic wave board. The outer layer of the plastic wave board allows the double-layer wave board to increase its heat-resistant temperature and service life by increasing the heat resistance of the outer layer of the plastic wave board.

The outer layer of the plastic wave board 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, making the double-layer wave board of the invention suitable for outdoor roof use.

By the double-layer wave board of the invention, the main effects can be achieved as follows:

The invention utilizes the outer layer of the plastic wave board disposed above the inner layer of the plastic wave board and is more weather-resistant than the inner layer of the plastic wave board, can increase the service life, and the double-layer wave board can improve the heat resistance, the impact resistance, the weather resistance, and the ultraviolet protection function. , providing 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 1 and 2, the present invention refers to a wave board for use in a roof. The double-layer wave board 1 includes a plastic wave inner layer 11 and a plastic wave board inner layer 11 disposed above the plastic sheet. The inner layer of the wave board 11 is weather resistant plastic wave outer layer 12.

The inner layer 11 of the plastic wave board is made of PVC or PC plastic material, so as to maintain the advantages of light weight and good extensibility of the plastic material.

In the embodiment of the present invention, the production method of the inner layer 11 of the plastic wave board and the outer layer 12 of the plastic wave board of the double-layer wave board 1 can be integrally extruded, and the thickness of the extrusion is the same as the thickness of the general wave board.

The outer layer 12 of the plastic wave board of the invention is made of ASA resin, and the ASA resin is copolymerized by styrene, acrylonitrile and acrylic rubber, so in the production process, the ASA resin not only maintains the heat resistance and impact resistance of the ABS plastic. The main characteristics, the most important is the combination of acrylic UV protection and weather resistance, making the double-layer wave board 1 of the invention suitable for outdoor roof use, heat-resistant, impact-resistant, weather-resistant, and UV-resistant. And the effect of increasing the useful life.

The outer layer 12 of the plastic wave board of the invention can be added into the color material in the production process to form the desired color and the building features, in addition to being heat-resistant and impact-resistant, and can increase the aesthetic advantages of the double-layer wave board.

The double-layer wave plate 1 of the present invention can be made into a double-glazed wave plate 1a of a glazed tile type as shown in Figs.

The outer layer 12 of the plastic wave board of the double-layer wave board 1 of the invention is made of ASA resin material which is heat-resistant, impact-resistant, weather-resistant and has ultraviolet protection function. In actual use, the double-layer wave board 1 is laid on the roof. The plastic inner wave layer 11 has the advantages of light weight, and a thin layer of plastic wave board 12 with heat resistance, impact resistance and weather resistance is provided on the inner layer 11 of the plastic wave board to provide a double layer. The heat-resistant temperature of the wave board 1 increases the heat resistance, impact resistance, weather resistance, UV protection function, and the effect of increasing the service life, so that the consumer can use the double-layer wave board 1 on the roof to achieve heat resistance, impact resistance and weather resistance. Sex, so that the double-layer wave board 1 can not only reduce the damage rate, but also provide consumers with excellent usability.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the patents of the present invention. Other equivalents of the patent spirit of the present invention are all within the scope of the invention.
