Abstract

The manufacturing method to make an wood plate engraved in relief includes a first step to make a negatively engraved silicon rubber forming die (2'), a second step to make a mixture and a third step to form a sculptured wood plate by pouring the mixture into the silicon rubber die (2') and heating them. In the first step the silicon rubber is formed by pouring silicon rubber into an wood die engraved in relief with a curing agent and drying it. The mixture composition has 150 l of wood sawdust, 10 l of granite powder, 35-50 l of Formica, 3-5 l of ethylene monomer and a curing agent. The mixture poured into the silicon rubber die (2') is heated at 30- 40 deg.C for 2-3 hours, while the temperature is elevated by chemical reaction between the mixture and the agent.

The present invention relates to an embossed plate that is attached to the intestine or the front surface of the suture and a method for producing the mold. Embossed boards attached to Jangong, etc. are generally impossible to mass-produce because they are carved by human hands, and because of the labor costs of the engraver, the production cost is excessive, so the furniture attached with embossed boards is expensive. The general public was difficult to purchase.

In the past, urethane was poured into a molding mold in which a desired shape was sculpted, and thus, a molded sheet material of a carved shape was embossed. There were various drawbacks as follows.

Firstly, the mold value is expensive, and secondly, since the elaborate molding part of the mold is easily corroded due to contact with chemicals (for example, release agent, etc.), the molding part may be damaged and dirt may be attached. It is not easy to clean and shorten mold life. Third, it could not reproduce fine pattern of irregularities and especially wood grain (Nate, knot, etc.). Fourth, synthetic resin plate such as urethane molded like carved material It was treated as a low-cost product because it became monochromatic in color.

The present inventors have focused on the above-described conventional defects, and researched on the fact that molding the material of a mold by using silicon rubber instead of metal or aluminum alloy could solve such defects. The mold made of phosphorus metal or the resin made of synthetic resin has problems such as heat resistance and durability, so that the mold is deformed or soiled. Therefore, the above-mentioned problem is solved by using a silicone rubber mold having high heat resistance and not sticking to the surface, thereby achieving the desired purpose. It was found that this can be done to complete the present invention.

It is an object of the present invention to reproduce the wood grain pattern with the irregularities of the pattern, and since the precise molded part is not corroded by chemical contact, it is possible to mass produce a uniform product, easy to clean the mold, and its life is relatively long, It is to provide an engraving embossed carved mold with easy to handle because of the light weight, and another object of the present invention is to provide a method for producing a carved engraving and wood grain carved plate engraving with the above-described improved embossing. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings as follows.

1st process

In consideration of the wood grain pattern of the wood board to be carved with embossing, the wood board is selected, and as shown in Fig. 1, a wall is formed on the outer periphery of the wood board carved into the desired shape by embossing, (1) The liquid silicone rubber (SILICON RUBBER) (2) added with a small amount of hardener is gradually evenly poured to prevent bubbles from being formed, followed by natural drying or heat drying, followed by silicone rubber molding. Lifting the frame (2 ') out of the carved wooden board (1) and turning it over turns the carved irregularities on the surface of the silicone rubber molding frame (2') in an intaglio form, and at the same time, the wood grain pattern of the wood board is precisely displayed. A mold of fine silicone rubber is obtained.

2nd process

Evenly mix wood sawdust with 200 liters of 200-300 mesh powder and 10 liters of 200-300 mesh granite powder.Then, 35-50 liters of Hoikaka and ethylene monomer 3-, which consist mainly of poriechiren and ethylene monomer. Dilute the liquid homomica by mixing about 5 L and mix uniformly in the mixer.

In a homogeneous mixture (sawdust + granite powder + liquid homomica) (hereinafter referred to as "primary mixture"), a small amount (liquid homomica) ) Is added and mixed uniformly (hereinafter referred to as “secondary mixture” (3)).

If you want to increase the strength of the carved plate and at the same time increase the brightness of the color, you can mix the same amount of clamshell powder instead of granite.

3rd process

After slowly pouring the secondary mixture 3 prepared in the second step into the silicone rubber molding die 2 'manufactured according to the first step so as not to form bubbles, and heating it at a temperature of 30 ° C-40 ° C for 2-3 hours. Engraved plate (3 ') consisting of the secondary mixture (3), which was first dried by raising the temperature of the secondary mixture to 50-60 DEG C by heating and heating by the chemical reaction between the secondary mixture and the curing agent. (2 ') sculpted plate (3') that is detached from a silicone rubber molding frame (2 '), turned over, placed on a flat glass plate or plywood, completely dried and embossed, and at the same time reproduces a fine grain pattern. You get

The carved sheet 3 'molded in this way can be mass-produced in a variety of sizes, such as the entire intestinal door, the entire assembly, or a part, depending on the size of the silicone rubber molding frame 2'. It is used by harmoniously attaching with adhesive on the front and back of doors. In the present invention shaped plate 3 'is soaked in the primary mixture and secondary mixture (3) as the rosin temperature of the rosin contained in the wood sawdust is heated, so that the color of the wood itself The engraving plate 3 'molded in the third step has a color body in an intermediate coating state.

In the case of finishing the material to enhance the engraving plate (3 ') of the present invention, attaching the engraving plate (3') to the place where necessary, such as jangnon, suture, doors, etc. with an appropriate amount of pigment to make the wood grain pattern appear more clearly. When the mixed paint is applied to the surface of the engraving plate 3 'and then wiped with a rag after 1-2 minutes, pigment is deposited on the fine groove of the engraving plate 3', and no pigment is deposited on the ring part such as rings. Because it is not or less deposited naturally color difference is a very useful invention that will not only form the same uneven pieces on the surface of the uneven pieces of the engraving plate, but also to show wood grain pattern (knight, knot, etc.).

Claims (2)

According to the first process, a liquid silicone rubber (2) added with a small amount of hardener is poured into a wood carving mold (1) having a wood grain pattern and engraved with embossing, and then naturally dried or heat-dried and engraved intaglio on the surface, and the wood grain pattern Method for producing a mold made of silicone rubber 2 'finely engraved. According to the 2nd and 3rd processes, 10l of 200-300 mesh granite powder or 10l of 200-300 mesh clam shell powder is evenly mixed with 150l of wood sawdust powder (200-300 mesh), and then to 35-50l of Homica A small amount of liquid homomica diluted by mixing 3-5 liters of ethylene monomer was added to the primary mixture uniformly mixed in a mixer. The secondary mixture (3), which was uniformly mixed by adding economical efficiency, was poured into a silicone rubber molding mold (2 ') and heated to the secondary mixture (3) when heated at a temperature of 30-40 ° C for 2-3 hours. A method for producing a piece of plate 3 'formed by chemically reacting with a mixed hardener to increase the temperature to 50-60 ° C., and to dry it first on a glass plate or plywood.
