Description

Panel and Manufacturing Method Thereof {A PANEL AND ITS MAKING METHOD}

The present invention relates to a panel and a method for manufacturing the same. Specifically, an alloy composition comprising cellulose extracted from a plant, a panel made of the alloy composition, and a foam layer in the center layer of the panel using the alloy composition. The panel is formed and the outer layer is formed with a non-foaming layer and a method for producing the panel.

More specifically, the method for manufacturing a panel with a foam layer of the present invention forms a foam layer in which a foaming composition with cellulose and an additive is added to the center layer of the panel, and the outer layer of the panel is a non-foamed layer with cellulose. To form, the foam layer and the non-foaming layer relates to a method for producing a panel formed by co-extrusion using a co-extruder.

In the case of synthetic wood, physical properties affected by the external environment such as temperature and humidity, that is, weather resistance is weak, especially when the high temperature and humidified, there is a problem in the expansion of its use due to severe warpage or deformation due to the load. In addition, the use of wood flour material generally has a significant decrease in mechanical properties compared to general-purpose plastics, so that by adopting a method of changing the structure of the product, such as a thicker thickness, problems such as weight reduction compared to existing wood materials remained. For example, when 40 parts by weight of wood powder is added to 100 parts by weight of vinyl chloride resin, and is bonded through a general binder and then molded, the impact resistance and tensile strength of the vinyl chloride composition are about 10 to 20 compared to the case where no wood powder is added. In addition to the level of only about%, the moisture tendency of the moisture of the wood powder and the high discoloration by the external drag has a disadvantage in that it is easily discolored and easily deformed or broken.

On the other hand, in the general extrusion process, it is difficult to extinguish foamed and non-foamed resins having completely different characteristics in one production process. It is a situation that a product is made through a post process such as attaching a transfer sheet.

The present invention has been made to solve the above problems, an object of the present invention is to minimize the deformation of the heat-resistant deformation due to temperature through the grafting of various materials specialized in the temperature, humidity, flame retardant properties reference value, and deformation against load and moisture It is to provide a panel and a method of manufacturing the same that has dramatically increased the performance, corruption and weight reduction of the product.

Another object of the present invention is to provide a panel and a method for manufacturing the same, which implements an appearance texture similar to expensive wood, and can replace a problem wood during construction and after-care and fire occurrence.

It is still another object of the present invention to provide a method for manufacturing a panel in which a post-processing process is not required separately for molding two materials having completely different properties.

As can be seen in Table 6, Examples 4, 5, and 6, which are flooring materials manufactured using an alloy composition containing cellulose, are flooring materials manufactured using an alloy composition including wood powder instead of cellulose, and Compared to 3, it can be seen that compared to Example 1, which is a flooring manufactured without using cellulose and wood flour, it shows more improved performance and physical properties. Accordingly, it was found that panels such as flooring and inner wall finishes made using the alloy composition comprising cellulose of the present invention have improved performance over conventional products. In Table 6, the meaning of 'comprehensive evaluation' is a general evaluation result for a general flooring generally used and a flooring made of an alloy composition including cellulose of the present invention. It can be seen that the flooring material of the present application made of an alloy composition including cellulose is superior in terms of long-term weather resistance and deformation.

Next, the performance comparison evaluation for the flooring material and general flooring material which provided with the foam layer of this invention was performed. Table 7 shows the components used in each example and whether the foam layer was formed.

As can be seen in Table 7, Example 8 is a non-foamed flooring material of PVC material and the same as the components of Example 1, Example 9 is an unfoamed flooring material of the wood powder composite material of Example 3 It is the same as the component. On the other hand, 9, 10, 11 in the embodiment is a flooring material made of an alloy composition containing the cellulose of the present invention. Example 9 is a flooring made only of an alloy composition comprising cellulose without adding a blowing agent, the constituents of which are the same as in Example 5. In Example 10, a non-foaming layer was formed of an alloy composition containing cellulose on an outer layer of a flooring material, and a foaming agent was added to an alloy composition containing cellulose on an inner layer of a flooring material to form a general foaming layer having a specific gravity after foaming of 0.8. to be. In Example 11, a non-foaming layer was formed of an alloy composition containing cellulose on an outer layer of a flooring material, and a foaming agent was added to an alloy composition containing cellulose on an inner layer of a flooring material to form a general foaming layer having a specific gravity after foaming of 0.8. to be. Example 10 and Example 11 are different from Example 9 in that the foam layer to which the foaming agent was added was formed in an inner layer, and the other components are the same.

The flooring materials of Examples 7 to 11 were evaluated for specific gravity and degree of deformation of the finished product.

Specific gravity

Specific gravity was measured using ASTM, which is generally used to measure the mechanical properties of plastic materials around the world. Table 8 below shows the evaluation criteria for long-term weather resistance.

evaluation standard ★ Less than 1.1 ☆ Within 1.1 to 1.3 ◇ More than 1.3

Evaluation of Deformation Degree After Assembly

The deformation degree of the flooring material manufactured by Examples 7-11 was measured. The measurement was performed by attaching a weight of 5 kg after assembling the flooring and standing for 72 hours at 50 ° C. to observe the degree of deformation visually.

evaluation standard ★ Bent to less than 1 cm ☆ Curved within 1 to 3 cm ◇ Bent more than 3 cm

As can be seen from Table 1, in the case of the flooring manufactured using the composition containing the cellulose of the present application (Examples 9, 10, 11), PVC flooring material (slashing example 7) or wood ash composite material flooring ( It was superior in the specific gravity and the deformation degree than Example 8). On the other hand, it can be seen that the flooring material (Example 10, 11) having a foam layer in the inner layer is better in specific gravity than the flooring material (Example 9) does not have a foam layer in the inner layer.
