Description

Embossed bed mat with voids using epoxy

The present invention relates to a bed mat having embossing and air permeability by combining molding with a combination of natural stone (cobblestone) and various dictations to a functional epoxy, and more particularly, an epoxy which is a special aqueous substance including a large molecular weight in an epoxy base resin. The present invention relates to a method for producing a healthy bedside product using a first composition composed of a resin, a flame retardant, an antifoaming agent, an amine curing agent, a second composition and a natural stone.

The simple functions of the bed mats that are generally used can be divided into two types: hard and soft. The hard type is mainly marble, while the soft type is spring-wrapped mat.

In addition, there are various types of bed mats that have functionalities, and they express anthropological characteristics in their own way, providing a comfortable and comfortable bed, and gaining great entertainment from customers.

However, research and development including the human health is thought to be constantly making efforts in keeping with the development of the industrial society. As a result of research and development for the development of a healthy bed mat for the human body of a completely new concept that meets such expectations, the usual epoxy Resin A natural stone (cobblestone) of the appropriate size is mixed with a conventional epoxy resin to make a surface layer by compressing plastering to make the surface smooth, then hardening and demolding the panel to make it comfortable and comfortable. It is about the production method to commercialize the bed mat that can provide.

Hereinafter, the present invention will be described in detail.

In order to provide bed mats using epoxy resins, the research papers of developed countries, which have produced epoxy structures and conducted numerous studies as many as the use of chemical resins in contact with the skin of the human body, investigate the harmlessness to the human body. On the other hand, the existing bedside has the hard and hard feeling as described above and the soft type with the cushion, which is the part of the skin that closes the skin when the bed has the hard and hard feeling. This impairs the smooth ventilation, and especially in the summer when the temperature is high, the part where the skin and the skin are anchored may cause various skin diseases due to the lack of oxygen supply.

In the case of marble, when the temperature is low, the direct ondol function using electric coil is harmful and the touch of low temperature of marble is harmful and the comfort can be impaired in high summer. Comfortable and comfortable bed In order to Metro, how reliable is the harmlessness of epoxy resin to human body and should be widely panelized, so that no deformation should be shown, and it is able to cope with chlorine emission from human body and other materials. It gives a soft and hard feeling, giving it a soft touch and a smooth surface, while the natural beauty of the material stands out.

In addition, the present invention has been completed by having an embossed shape and a space to have a desired ventilation.

These bed fields provide epoxy base resin, cresol novolac epoxy resin among epoxy resins of high molecular weight, epoxy constituents of cyclo-epoxy epoxy resin in a special composition, and petabromo diphenyl oxide as a flame retardant. As the polysiloxani-based antifoaming agent, the metaxylene diamine (aromatic modified amine) isopropyl diamine (aliphatic modified amine) as a hardener for the weight of the first composition of the resin component, the curing component comprising an epoxy base resin, Epoxy composition consisting of parts by weight of the second composition and the weight of the epoxy composition with the main composition of the epoxy composition to the weight of the natural stone using a size other than the natural stone here, by pressing plastering to a certain thickness using a tempered glass sheet molding and cured To complete.

The diameter of natural and non-natural materials is 3 / mm to 15 / mm and the panel thickness is applied to 20 / mm to 50 / mm. In addition to natural stone, also includes oval round jade ball, natural amethyst ball, jade stone ball. Paneling is done using glass dictation, wooden neck dictation, etc.

The new bed mat is formed by adding an appropriate amount of the epoxy resin prepared above to natural stone or various materials in order to have air gaps to allow ventilation and to have a smooth and embossed surface layer. If you add too little, you will not be able to achieve the desired functions and properties. The proper mixing amount of resin makes it possible to form voids between materials using natural stone or various materials, which not only has a good ventilation, but also has a good physical property such as "human resistance" and "resistance of deformation" from the weight of the human body. Indicates. In addition, by using the air permeability to circulate the warm air installed on the bottom of the bed mat will have the ability to run through the air gap. In addition, the surface mat is smooth and embossed, so the developed mat is a new function that is completely different from the past with a comfortable breathability and soft touch.

In addition, the epoxy resin is composed of a transparent resin and mixed with other materials besides natural stone to enhance the aesthetics by making the natural color of the material at the time of crimping plastering look better.

Meanwhile, when developing such a product, the transparent epoxy composition having smooth physical properties is described in more detail as follows.

Epoxy Basic Resin 75 ~ 85% by weight Epoxy molecular weight 5 ~ 10% by weight Cresol Novolac resin 5 ~ 10% by weight Cyclo-Eripic resin, a special composition, Flame retardant Pentabromo diphenyl oxide 2 ~ 5% by weight Defoamer 0.1 ~ 60-50% by weight of metaxylene diamine 30% by weight of 30 parts by weight of a main body consisting of 0.2% by weight of 40-50 parts by weight of a curing agent consisting of 10% by weight of epoxy base resin is used.

Unlike the epoxy resin composition, the transparent epoxy resin of the present invention has a very high crosslinking density and a heat resistance of 120 ° C. or higher, so that no deformation is observed and no yellowing property and adhesion. As a composition with excellent wear resistance and weather resistance, it is molded and mixed with other materials such as natural stone by using a molding mortar to show the color of the material when demolding, as well as excellent in the beautiful appearance.

And in manufacturing molding molding, attach the support of metal or plastic mold of the desired thickness and shape to the tempered glass plate of the standard, apply the release agent, and mix the selected material and the composition epoxy resin 10: 1 After putting, using a prepared plastering knife pressed to plaster to increase the smoothness. The curing time of the resin is cured at room temperature 20 ℃ 12 hours.

And the same resin is used to coat in the first secondary injection form, cured again, and finished by demolding.

In this case, the injection type coating is used to ensure that the gap between the formed material and the material can be firmly bound so that the formed voids are not filled, and the resin is repeatedly overlapped with the air spray to allow the resin to flow evenly from the surface layer. Sprinkle It is cured and then demolded product is placed on the bedside using wood and metal that is manufactured separately.

On the other hand, here, the bed is produced to seat the bed mat is made of wood and metal in various ways, such as one-person or two-person or circular shape, such as the installation of an ion wind device, the device is hot air rises By using the air bed at the bottom of the bed to create a space layer and evenly circulated through the metal pipe hot air is slowly circulating through the space to develop the ondol function through the air gap of the developed bed mat,
