Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring material using a fibrous glass and a mesh in a synthetic resin mixture,

The present invention relates to a flooring material using a fiber mixture and a mesh in a synthetic resin mixture and a manufacturing method thereof. More particularly, the present invention relates to a flooring material comprising a mixture of calcium carbonate (stone), silica sand, (Deck), a stepped plate, and a building interior / exterior material, which is formed by flattening a vibrator (vibrator) by inserting any one of fiber glass, an iron core and a mesh between the lower layer and the upper layer, The present invention relates to a floor material using grass and a mesh and a manufacturing method thereof.

In addition to the development of plywood manufacturing technology, it is well known that a lot of plywood with excellent physical properties is provided, and the plywood is used. When it is used for flooring such as flooring and other building materials, And its surface is coated with a resin paint to impart resistance to water resistance and scratching.

As an example of manufacturing this kind of indoor flooring flooring, there is a method of manufacturing a flooring board by adhering a veneer single plate to a synthetic upper side with a urea resin, but it has a disadvantage in that the manufacturing cost is increased, and water resistance and heat resistance are very weak.

As another example, in the case of a floor board manufactured by pressing a melamine resin impregnated paper (LPM) on the upper surface of a heavy fiberboard (MDF) at a high temperature and a high pressure, there is an advantage that manufacturing cost can be reduced. However, There are disadvantages.

In addition, although the plywood or heavy fiber boards used as the base material are usually processed in the dried state, the environment used and installed on the inner floor of the actual building is changed by the season and the change of the room temperature and humidity due to the change of seasons such as summer and winter, There is a phenomenon in which the connection site is widened or widened due to the internal stress caused by the shrinkage and swelling action, and it is difficult to maintain the initial bonding condition by chemical deterioration, and there are disadvantages such as diminished dimensional stability and water resistance . Also, it has a defective base plate because it is prohibited to use because it is harmful to the human body by adding toxic chemicals during preservation process.

On the other hand, the reinforced floor using HDF (Hight Density Fiderboard) can perform click processing and suspension construction, but it can strengthen the surface strength. However, since natural veneer can not be used, natural texture degradation and water resistance And it has a disadvantage of heavy weight.

In order to solve such a problem, Utility Model Registration No. 0399316 discloses an ondol floor of a wood fiber (wood particle) -propylene fiber composite base material.

The WPC (Wood Fiber Poiypropylene Hiber Composite Panel) is used as the main substrate of the ondol floor in the above-mentioned prior art, so that the water resistance which is the greatest disadvantage of the reinforced floor can be compensated. The disadvantage of the plywood floor complements the impact resistance, There is a problem that it is considerably difficult to obtain a flooring having a surface with a high gloss and a low scratch resistance due to the characteristics of the surface sheet.

In addition, in the case of the conventional plywood flooring, the veneer is adhered on the plywood, followed by coloring and coating by the roll coater, and the synthetic resin is forcedly injected into the veneer to reduce the surface hardness However, since the coloring process is performed by a roll coater in the case of coloring, it is impossible to directly use the wood (pattern) possessed by wood, which is an advantage of the veneer, and the disadvantages of surface hardness, surface scratch resistance, abrasion resistance, Or paints such as epoxy and acryl-based coatings are thickly coated. This is because the strength is so strong that the flexibility is lowered and it is easily broken.

In contrast to this, WPC (Wood Polymer Composite) method among several developed techniques for reinforcing the surface strength is to increase the strength and hardness by impregnating wood veneer (veneer) with resin, In some cases, the resin is forced into the pores and cell layers of the wood in a state in which the wood veneer is not attached to the plywood and is hardened by forcibly injecting. However, due to the expansion and contraction of the wood due to moisture, There is a problem that defective phenomenon such as shaving occurs.

On the other hand, in the case of the plywood manufactured by the melamine resin impregnation and overlay press method, when the veneer is laminated on the plywood, an overlay containing the veneer impregnated with melamine resin and aluminum oxide (Al2O3) is covered on the top of the veneer, , A high-pressure press is used to penetrate the inside of the veneer, which has a manufacturing method similar to that of a reinforced floor. However, this also has problems in that the economical efficiency in the production process is deteriorated due to an expensive cost and a troublesome working method, It is pointed out that it is difficult to obtain the surface texture by the coating method.

In order to prevent such disadvantages, calcium carbonate and synthetic resin are mixed in a weight ratio of 6: 4, and 97 to 99.8% by weight of the mixture, 0.2 to 3% by weight of a dye is mixed and stirred to form a lower layer; An intermediate layer formed with a fiber glass on the upper side of the lower layer; And an upper layer formed by mixing calcium carbonate and synthetic resin at a weight ratio of 7: 3 to the upper side of the intermediate layer and mixing and stirring 97 to 99.8% by weight of the mixture and 0.2 to 3% by weight of a colorant by molding. , But it does not require any shrinkage and expansion, and has good water resistance, heat resistance and durability. However, the time required for press molding is about 30 minutes and not only the consumption of press molding time but also the preparation time for press molding There is a problem in that productivity and economical efficiency are lowered due to a problem that it takes more than 40 minutes to perform the molding process as a whole because the time for separation from the post press and the time for demoulding are large.

Since the bottom material 30 is formed by mixing calcium stearate, silica sand and marble particles with synthetic resin, flame retardancy is imparted, the maximum flexural load is increased, rigidity is improved, warpability is hardly generated, At the same time, there is almost no change in weight due to the water absorption rate, and the impact strength is greatly improved as compared with that of a general deck. Therefore, even when a temperature change such as summer or winter is severe, expansion and contraction do not occur, Since the screw can be directly fixed to the frame of the floor after the hole is formed, it is possible to provide an effect that the screw is not separated or deformed even when a long period of time is elapsed.

The present invention relates to a method for manufacturing a floor material having a high tensile strength, flame retardancy and impact strength by forming a floor material having a certain thickness through the vibration of a vibrator by supplying any one of calcium carbonate, silica sand, And to provide a very useful invention that improves the performance.
