Interior Finish Building Materials For Using Waste Solid And Manufacturing Method There Of}

The present invention relates to the interior and exterior building materials that significantly improved the waterproof and aging resistance by using general waste such as waste PVC, waste vinyl, waste fiber, waste wood, and more specifically, to crush and discard the waste waste to a certain size It is made of cardboard by ignition and integrated into a mixed composition of mesh board with synthetic resin solution and powder composition with high permeability, adhesiveness, flame retardancy and durability. It relates to a material and a method of manufacturing the same.

As is well known, in the case of construction, concrete plywood is used to attach film to general plywood, and in general, plywood to which film is applied is usually used 2-3 times or so. none.

Recently, due to the rapid development of the industry, the waste materials generated at the industrial site or at home are increasing rapidly. In particular, waste clothing, waste fiber, construction materials waste, waste plastics, and waste glass are the largest amount of waste materials, and are difficult to dispose of them, making them a major social problem. It is true.

In addition, civil engineering and building materials used for various buildings and construction materials are mostly made of granite or marble, which is especially popular as a finishing material in buildings, but the price is very expensive, and the general public avoids using them. to be.

On the other hand, many treatment technologies for building materials using waste are introduced. Basically, waste materials that are discarded are collected and crushed to a certain size so that the level of durability, heat resistance, and flame resistance required for building materials can be exhibited. It is common to form a new product in the form of plywood by chemical coating treatment with various synthetic resin compositions on waste cardboard which has been crushed and processed.

However, in the multi-stage plywood coating structure by coating the synthetic resin chemicals, it was not possible to expect such effects on soundproofing, waterproofing and heat dissipation over a predetermined level. There is a disadvantage that it is not absorbed well and can easily be separated.

In addition, due to the nature of the chemical coating, there is a lot of waste powder generated in the process of operation and unnecessary consumption of the material, in particular, there is a physical structural limitation that the strength and lack of durability and heat resistance sufficiently to withstand in a harsh environment.

Of course, in order to increase the strength to thicken the thickness, but there is a problem that the weight is much more than necessary. For example, when the size of the plywood is 4 characters (1,200 mm) x 9 characters (2,400 mm) and the thickness is 12 mm, there is a inconvenience in that the functionality and economics are limited due to the heavy weight of 40 kg.

Accordingly, the present applicant has developed the technology to solve all the inconvenient points of construction materials and its manufacturing methods that have not been solved by using the wastes introduced so far. It is pulverized and spun to a certain size to make paperboard, and it is structured as synthetic resin liquid and powder composition with high permeability, adhesiveness, flame retardancy and durability, but it is light and yet integrated by the mixed structure of the mesh mesh mesh structure between these materials. It is an object of the present invention to provide interior and exterior building materials and a method of manufacturing the same using a new combination of wastes that can dramatically improve durability and flame retardancy in terms of structure and properties.

Internal and external building materials utilizing the waste of the present invention for achieving the above object, basically, any one of the waste such as waste PVC, waste vinyl, waste fiber, waste wood, such as crushed and burned cardboard to a predetermined thickness 100 wt% of waste paper, phenol resin and / or melamine resin, 20-60 wt% of synthetic resin solution to be penetrated into the waste paper, and phenol powder and / or melamine powder to waste paper penetrating the waste paper. It is composed of a powder coating agent, and a mesh mesh of the network structure is inserted into the compression between the both sides of the waste cardboard in which the synthetic resin liquid and powder coating agent are integrated, these components are compression molded to a thickness of 5-15 mm sheet thickness as a whole Achieve technical features. In particular, the synthetic resin solution and powder coating agent is preferably used when the building material is used for formwork, phenolic resin and phenolic powder, and when the building material is applied for interior materials, melamine resin and melamine powder are preferably used.

In addition, the manufacturing method of the interior and exterior building materials using waste according to the present invention, any one waste collected from waste such as waste PVC, waste vinyl, waste fiber, waste wood, etc. Winding up to shape the waste cardboard, impregnating the waste cardboard with a synthetic resin solution of phenol resin and / or melamine resin as an adhesive means, and penetrating the synthetic resin liquid into the waste cardboard; Applying a powder coating agent of phenol powder and / or melamine powder, which is a mixture of fine fiber coating powder, to the waste cardboard; Inserting a plate, and first preheat compressing (compressing) the laminate of the waste paperboard with the mesh plate inserted therebetween and hot compressing it. The final cooled compressed to around 10-30 seconds after a cold pressed has a technical feature that the process comprises the step of processing cut into a predetermined size.

The interior and exterior building materials using the waste of the present invention and its manufacturing method, by utilizing the waste resources, such as waste fibers, the new construction that significantly improved the durability and flame retardancy required in the interior and exterior materials, while being a cheap manufacturing cost It can be applied to various and convenient materials. That is, through the treatment method of penetrating and applying the synthetic resin solution and the powder coating agent to crush and burn the waste fiber, and to have adhesiveness and durability, the mesh plate of the mesh structure is inserted in the middle thereof, and then it is rolled and compressed. While reducing the weight of the weight lighter than about kg can basically improve the durability and flame retardancy significantly, and in particular can provide an effect that can significantly reduce the bonding failure and excessive weight generated in the multi-stage joining method.

As such, the interior and exterior building materials utilizing wastes of the present invention, in particular, waste fibers made of durable materials, are made of wood plywood using general wastes such as waste PVC and waste vinyl, waste fibers, and waste wood. It is an aging resistance and interior and exterior building material developed as a substitute, and is applied to various products such as formwork panels, which are indispensable in the existing construction sites used as wooden plywood, which can contribute to the effect of import substitution and economic development and employment of local communities. have. In particular, the interior and exterior building materials using waste according to the manufacturing method of the present invention can prevent environmental pollution and reduce waste disposal costs, and have a definite effect on income replacement and activation of local economy as well as on farm income. It is expected to be imported.

Figure 1 and Figure 2 is a work process drawing the interior and exterior building materials utilizing the waste of the present invention.
Figure 3 is a mesh structure of the mesh structure applied as an adhesive and strength reinforcement in the middle of the waste plate of the interior and exterior building materials utilizing the waste according to the present invention.

It will be described below in detail with reference to the drawings of the preferred embodiment attached to the specific structural relationship and manufacturing principle for the interior and exterior building materials and its manufacturing method utilizing the waste of the present invention.

First, the waste applied to the interior and exterior building materials using the waste of the present invention can be used by applying most of the general waste such as used waste PVC, waste vinyl, waste fiber, waste wood, etc. Application of cardboard material is desirable for both workability and functionality.

The present invention is used as a building material utilizing waste, basically mixed with the synthetic resin solution and powder coating agent of the meralmin and phenol and powder coating agent in a predetermined size mixed and penetrated and coated on the waste cardboard and the wire core of the mesh structure By combining the separate adhesive reinforcing means as a whole in the form of a thin plate, it is possible to satisfy both economical and various functionalities that were not expected at all in the existing waste recycling building materials.

The present invention, as shown in the working process drawings of Figs. 1 and 2, first, the waste cardboard which is the waste fibers dried by drying waste fibers (waste synthetic fibers) such as fiber and wool as the collected waste synthetic resins (10). Grind through small pieces to a size as small as about 40-80 mesh.

After the finely crushed waste cardboard is burned in a downy shape through the other surface machine 20, the waste paperboard of the other side is made of fiberboard having an appropriate (constant) thickness by using the front machine 30 and the punching machine 40. Shaped to a wound through the winder (50).

Continue to use phenolic resins or melamine resins selectively, or to apply these phenolic resins and melamine resins in order to enhance the performance of sheet products as a means of reinforcing construction materials such as permeability and adhesion to waste paper and flame retardancy and durability. The synthetic resin solution of the adhesive function is made using the mixed synthetic resin of, and then the waste cardboard, which is a fiberboard body which is continuously unwound in the winder 50, is combined in each of the resin adhesives 60 on both sides.

Then, the waste cardboard in which the synthetic resin liquid has sufficiently penetrated through the adhesive machine 60 is rolled, and it is applied as a powder coating agent which is a mixed coating agent of meramine powder or phenol powder which is a fine fiber solid powder. In this case, the powder coating agent applied to the waste cardboard is applied by spraying directly onto the waste cardboard at a predetermined interval through the coating machine 90, or in some cases, the powder coating agent is buried in the roller and the waste cardboard is naturally rolled. It can also be made to apply.

That is, the powder coating agent is directly applied to the waste paperboard, or the powder coating material is buried in the rubber roller and rolled onto the waste paperboard so that the powder coating material can be reliably penetrated to the back surface including the surface of the waste paperboard, and then the synthetic resin solution And a powder coating agent on both sides of the waste cardboard formed of an adhesive layer and a coating layer, and a subsequent processing operation in which all of the components are reliably integrally structured as a whole through an iron mesh that is a separate mesh structure in the middle thereof.

This is a cold press while the synthetic resin liquid and powder coating liquid are infiltrated and applied, and the iron plate network having a network structure is bound in the middle of the structure to be integrally structured, and then slowly cooled through the process of being transported to the process. By cold pressing (cold compression), such as Press), the iron plate network is finally penetrated into the waste cardboard stack can be completed in the form of a thin plate of a certain thickness.

In this case, the mesh structure of the steel plate inserted between the waste cardboard stacks and integrally used is an expanded metal (called Expanded Metal), which is a diamond shape by insulating and cold-rolling a hot rolled steel sheet at an appropriate interval. It is a mesh structure made of steel, which is made of hot rolled steel sheets or coils as is well known, and can be safely installed and used on a structure of a large area with a minimum amount and time, and has good projectability and ventilation. It will function to more dramatically double the adhesion and durability to the multi-stage structure.

That is, the conventional method was a method of constructing and bonding a multi-stage waste cardboard stack, but there was a contradiction in efficiency decline due to the generation of poor bonding and excessive weight (typically 40 kg level) generated in the multi-stage bonding structure. However, the building materials utilizing wastes through the manufacturing method of the present invention basically compensate for these drawbacks and basically roll the waste paper boards in which the synthetic resin and the powder coating agent are penetrated and applied, and then again for the waste papers in the form of sheets. After joining by inserting Expanded Metal, which is a steel sheet network of mesh structure, in the final stages, the product is finished as a durable and flame-retardant building material in a thin thin plate form that is light weight of about 12 kg through cold and hot pressing process several times. Can be.

Then, the present invention is the primary molded body by compressing the laminated body with a power of 1,000 Ton in pressing force in the preheating press 80 to maintain the temperature of 50-70 ℃ the laminated body of the synthetic resin solution, powder coating agent and penetrated and coated waste cardboard Configure At this time, the color of the dye pattern is formed together with the first moisture drying (evaporation), and as the moisture is dried, bubbles are not generated on the surface to maintain a uniform surface and prevent adhesion failure.

Subsequently, the first press compacted waste cardboard stack is compressed in a 1,500 Ton main hot press (hot roller) and cold press (cold roller) 82 maintaining a temperature of 120-150 ° C. At this time, the waste cardboard, which is a laminated heating compressive agent, is cold-pressed at 70-100 ° C., and then cold-pressed again at about 30-50 ° C. for about 20 seconds in a 500Ton compression type cold press 84 and durability as a building material required by the present invention. Product performance that basically meets flame retardancy can be completed, and the waste cardboard stack finally loaded and discharged through a loader can be cut (cut) to a certain size and used as a product.

On the other hand, building materials using waste produced and produced through the manufacturing method of the present invention can be basically applied as a formwork and interior materials, in the case of a formwork for the first time EM (expanded) mesh network of 8-10 mm thick Died metal), phenol resin is used as the synthetic resin solution, phenol powder is used as the powder coating agent.

In the case of interior materials, the thickness is within 5 mm, and the steel grid of the mesh structure does not necessarily have to enter. In particular, the synthetic resin solution (resin raw material) and powder coating materials used when applied for interior materials, it is preferable that the melamine resin and melamine powder can be used as a nonflammable material, a flame retardant material.
