Next, a method of manufacturing a foam panel for a built-in roof of a building according to the present invention will be described with reference to FIG. 6 is a flow chart showing a method of manufacturing a foam panel for a built-in roof according to the present invention.
A method of manufacturing a foam panel for a built-in roof according to the present invention includes a panel composition mixing step (S100) of blending a panel composition for forming a foam panel at a predetermined ratio, as shown in the flow chart of FIG. A panel composition mixing step (S200) of mixing the blended panel composition at a predetermined temperature for a predetermined time; A rolling mixing step (S300) of rolling the mixed panel composition using a roller for a predetermined time at a predetermined temperature; A calendering cutting step (S400) of calender-cutting the rolling mixed panel composition uniformly to the mold size; And a pressing step (S500) of foam-molding the calendered material at a predetermined temperature for a predetermined period of time, and foam molding to have a channel groove and an assembly part.
The panel composition mixing step (S100) comprises mixing 37.5 wt% of LDPE powder, 37.5 wt% of EVA powder, 21 wt% of CaCo3 powder as a reinforcing agent, 2 wt% of a crosslinking agent, 2 wt% of a foaming agent And is blended at a blending ratio. It has been confirmed that the compounding ratio is an optimal value obtained from experimental results obtained by the inventors of the present invention, prototypes in the manufacturing process, and results of research.
Here, the panel composition mixing step (S100) may further include mixing 5 to 20 parts by weight of at least one additive powder of charcoal, silver nano and loess with 100 parts by weight of the panel composition.
Next, the panel composition mixing step (S200) is performed so that the panel composition is mixed at 90 ° C to 120 ° C (preferably 110 ° C) for about 5 to 15 minutes (preferably about 10 minutes). The temperature and time in the panel composition mixing step are the numerical values derived from the experimental results to make the panel composition into a solid gel state so that smooth operation can be achieved in the subsequent process.
Subsequently, the rolling mixing step (S300) is performed for about 9 minutes at about 90 ° C to 100 ° C using an 18 to 22 inch roller. The predetermined time and temperature of this rolling mixing step is also a numerical range derived from the physical properties that allow a smooth process to be performed in the following cutting and pressing steps.
The pressing step (S500) is a step of foaming molding at a predetermined pressure for about 10 minutes to 15 minutes (preferably about 12 minutes) at 145 ° C to 170 ° C through an expansion molding machine, Like channel grooves are formed, and the assembled portions are formed at the edges of the two adjacent sides and the neighboring two sides.
Here, it is preferable that the flow channel formed in the pressing step (S500) is inclined from one side to the other side of the molded article to be molded or inclined toward both sides from the central part.
By forming the flow grooves in the molded product as described above, the flow path space is provided on the flat surface of the molded product, thereby ensuring air permeability, so that even if moisture is generated due to the temperature difference between the inside and the outside, moisture can be easily removed, So that they are easily collected in the flow path groove.
In addition, the assembly part formed in the pressing step (S500) may be configured such that a seating groove formed on one side (i.e., an upper side) of the edges of two adjacent sides of the rectangular molded article to be formed is formed, And the
Meanwhile, the method for manufacturing a foam panel for a built-in roof of the present invention further comprises forming a polymer-absorptive material receiving groove in a channel groove in a pressing step (S500), and after the pressing step (S500) And a step (S600) of inserting a polymer absorber into the polymer absorber.
The polymeric absorber receiving grooves may be formed over the entire length of the channel grooves or may include a plurality of receiving grooves formed at predetermined intervals.
The polymer absorber provided in the polymer absorber-providing step (S600) is made of a polyacrylate-based polymer capable of absorbing water at least about 50 times its own weight, and it is environmentally friendly Highly absorbent resin. Examples of the polyacrylate-based polymer include sodium polyacrylate resin, polyamide-sodium acrylate resin, starch-sodium acrylate resin, and chitosan-sodium acrylate resin.
Here, the polymeric absorber provided in the polymeric absorber receiving groove may be composed of a mixture further containing activated carbon. By including activated carbon in the polymeric absorber in this manner, it is possible to suppress the generation of germs due to moisture due to the characteristics of the activated carbon and to provide a deodorizing effect, thereby providing a pleasant environment.
As described above, according to the foam panel for building built-in roof according to the present invention and the method of manufacturing the same, it is possible to provide an eco-friendly product which is simple in construction, has no deformation,
In addition, according to the foam panel for building built-in roof of the present invention and the method of manufacturing the same, a flow path space through which a fluid can flow can be easily dried when a small amount of moisture or water droplets is generated due to temperature difference between inside and outside, And furthermore, by providing the polymeric absorber in the flow path space, it is possible to effectively cope with moisture generation due to the difference in temperature between the inside and the outside, thereby providing a pleasant environment.
The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but rather are not intended to limit the scope of the technical idea of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
