Description

Mold for manufacturing artificial marble {MOLD FOR PRODUCING ARTIFICIAL MARBLE}

The present invention relates to a method of manufacturing a mold for manufacturing artificial marble. In particular, the present invention relates to a mold for manufacturing artificial marble which can produce high quality artificial marble by minimizing deformation of the mold during manufacturing of artificial marble.

Conventional building wall materials have been used to cut stones into certain shapes and to smoothly polish their surfaces. However, due to various problems such as limited resources, environmental destruction, and transportation doors, artificial marble has recently been used a lot.

Artificial marble is blended with additives such as natural stone powder, minerals and / or resin chips, to bases such as acrylic resins, unsaturated polyester resins and / or epoxy resins, or cements, and additives such as pigments as necessary. It is an artificial composite that embodies the texture of natural stone.

Such artificial marble has a beautiful appearance and excellent workability, is lighter than natural marble, and has excellent strength and is widely used as various interior materials such as counter tables and building exterior walls.

Artificial marble is mainly produced by pressurizing the mold after filling the above-mentioned material in a constant mold.

The mold mainly consists of a bottom plate and a top plate, and the bottom plate and the top plate each have a multi-layer structure made of a combination of rubber and fabric.

This multi-layered form is mainly composed of rubber layers and fabric layers. The bonding of the rubber layers and fabric layers is made by stacking them and passing them between the pressurized rollers.

The mold is made of a certain size or more in order to increase the production yield, and the situation is to use a mold of more than a certain size of marble made by using a mold, and then cut the leg to a certain size.

However, when manufactured using the heat-pressing rollers as described above, the length of the width is limited, it is a situation to manufacture a mold by connecting the sheets produced in multiple layers to each other.

In this way, when the mold is manufactured by connecting sheets made in multiple layers, the lifespan thereof is not only reduced, but also the quality of the artificial marble that is easily deformed and manufactured may be degraded.

In addition, since the rubber layer and the fabric layers are attached only by thermal pressure without a separate adhesive, there is a case where the bonding between them occurs or is not ideally made.

That is, the artificial marble is filled in the space formed on the lower plate and the upper plate is pressed to obtain the artificial marble of a predetermined shape. In this case, when the thickness and bonding of each layer of the upper plate and the lower plate is not ideally made, deformation of the upper plate and the lower plate occurs, which makes it difficult to obtain high-quality artificial marble. In addition, there is a problem that the deformation easily occurs and the life is shortened.

Accordingly, an object of the present invention is to provide an artificial marble manufacturing template that can be made of artificial marble of high quality, so that the thickness and bonding of each layer of the top plate can be made ideally.

Still another object of the present invention is to provide a mold for preparing artificial marble, in particular, a press plate for manufacturing the top plate in a multi-layer manufacturing process, by adding an adhesive between the layers to increase the bonding reliability of each layer. .

Another object of the present invention is to provide a mold for manufacturing artificial marble that can prevent deformation of the product by forming the upper plate by a press body to form a single body of sufficient size.

In the state in which the first layer and the second layer are adhered, the adhesion of the third layer and the third layer and the adhesion of the second layer and the third layer are performed by a primary heat press operation with a contact agent therebetween. The pressure of the second press operation may be 150-170 Kgf / cm ² .

The thickness of the rubber sheet forming the second and fourth layers may be 1.6-1.8 cm.

The adhesive may be made of N.N'-CM-PHENYLENE DIMALEIMIDE.

A fluorine or silicon coating layer may be further formed on the fourth layer.

According to another embodiment of the present invention, in the mold for manufacturing artificial marble comprising a lower plate having a molding space and an upper marble formed by pressing the artificial marble material filled in the molding space using an external force, the lower plate is
