Abstract

PURPOSE: A bonding method of untreated sleeper and patterned sleeper in a patterned sleeper wrapping molding is provided to prevent the separation between untreated and patterned sleepers through a chemical reaction with the volatile matter contained in an oil-based coloring material by differentiating the bonding substances of the both sides in the process of a patterned sleeper wrapping molding. CONSTITUTION: A bonding method of untreated sleeper and patterned sleeper in a patterned sleeper wrapping molding comprises the following steps of: coating hot melt glue on only the front side of the growood paper coated on both sides; sticking the patterned sleeper to the back of that growood paper with blending water-glue for wood and papering-glue in a ratio of 2 to 8; then bonding the untreated and patterned sleepers using by hot-air of 450°C. Therefore, the separation of the patterned sleeper is protected by the differentiation of the glue substances between the coated both sides.

Description

Joining method of material wood and veneer in veneer wrapping molding {.}

The present invention relates to a method of joining a material wood and veneer in the process of producing veneer wrapping molding, and more specifically, by using the adhesive coated on both sides using a coated paper coated on both sides with the volatile material contained in the oil paint It is a method of joining material wood and member wood by chemical reaction.

In general, veneer lapping molding uses a nonwoven fabric coated with hot melt (HOT MELT GLUE) on both sides to join the veneer and the material.

However, the veneer wrapping molding manufactured in this way has no problem in appearance, but when the oil coating is applied to the veneer wrapping molding, the material and the veneer of the wood are formed by the chemical reaction with the hot melt (HOT MELT GLUE) by the volatile substances included in the oil coating. Problems that cause peeling will occur.

In order to solve the above problems, the present invention uses oil-based paints by varying adhesive components on both sides by using a coated paper on both sides instead of a non-woven fabric coated with hot melt (HOT MELT GLUE) on both sides when joining material wood and veneer in an existing product. It is an object of the present invention to block the peeling of the material and non-woven fabric by the chemical reaction during use.

In order to achieve the above object, the present invention is a step of applying a hot melt (HOT MELT GLUE) to the front surface of the coated paper on both sides in the process of joining the material wood and veneer, water-based adhesive and paper on the back of the coated paper Mixing the veneer by mixing the glue 2: 8, it is characterized by consisting of the step of joining the veneer and the veneer using the 450 ℃ hot air after the step.

Drawings are cross-sectional views illustrating the components of veneer wrapping moldings.

Detailed description of the above is as follows.

HOT MELT GLUE, which is used as an adhesive for veneer and material, has the advantage of being easy as an adhesive for veneer, but it has a disadvantage of causing chemical reaction with volatile substances such as thinner and benzol, resulting in peeling phenomenon.

In order to compensate for the disadvantages of the hot melt glass (HOT MELT GLUE), both sides of the coated paper is used as a device to block the chemical reaction of the volatile and hot melt (HOT MELT GLUE).

By applying hot melt on only one side of coated paper on both sides, it prevents chemical reactions that occur when volatile materials are applied to veneer wrapping molding products.

In this state, the cross section not coated with HOT MELT GLUE is contacted with veneer by mixing 2: 8 with an aqueous adhesive and a paper paste.

Coated wood and coated veneer through the above process is bonded to the material using a hot air of 450 ℃.

The veneer wrapping molding produced in this way is to prevent the peeling of the veneer and the material wood by the volatile material by changing the adhesive component of both sides on the double-coated grout.

As described above, the present invention is a hot melt (HOT MELT GLUE), which is an adhesive for the veneer and material wood when oil-based paint is used in the veneer wrapping molding product by varying the adhesive components of the front and back surfaces of the coated paper coated on both sides during the joining of the veneer and the material wood. By blocking the chemical reactions caused by volatile substances), peeling phenomenon, which is the biggest problem of veneer wrapping molding products, can be prevented.

Claims (1)

In the process of joining the material wood and veneer, hot melt (HOT MELT GLUE) is applied only to the front surface of the fixed paper on both sides, Step of contacting the veneer by combining the aqueous adhesive for woodworking and the paper paste on the back of the coated grout paper, Joining method of the veneer and the material wood in the veneer wrapping molding consisting of the step of bonding the material wood and veneer using the 450 ℃ hot air after the step.
