Description

Background of the Invention [0001] Velcro wallpaper and method thereof [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a velcro wallpaper and a method of manufacturing the same, and more particularly, to forming a velcro hook or loop in a wallpaper or medium according to a velcro insertion type molding method.

Typical wallpaper installation is to attach nonwovens to the wall, and apply the paste to the wallpaper product and attach it to the wall. At this time, when applying the grass to the nonwoven fabric and the wallpaper, a long aging time is required in order to secure the initial tacky property, and the possibility of contamination to the grass and the dimensional change of the product due to the grass occur. Also, when the wallpaper is applied by the adhesive construction, it is difficult to demolish when constructing a new product.

Wallpaper refers to paper that is used to protect the wall of the room such as a home or office and is used for decorating. There are various kinds of patterns, and there are only simple stripes close to plain. Waterproof wallpaper can be used for water There is also a moisture-proof effect.

Recently, such wallpaper has been recognized as a very important factor in interior decoration, and various types of wallpaper are used according to the use of each space. For example, living space used as open space exposed to people or visitors is warm The patterned wallpaper of the atmosphere is used, and the bedroom used as the resting space uses the pastel-tone wallpaper with a cozy atmosphere, and the selection of the wallpaper is made considering the use of the space and the person who mainly uses it .

However, it was not easy to change the wallpaper or change it according to the use.

Embodiments are intended to easily adhere wallpaper or facilitate change or replacement of wallpaper pattern.

In the embodiment, a velcro layer of a hook or loop structure is formed on the front surface of a wallpaper or a medium so as to facilitate the change or replacement of the wallpaper pattern, or attach and detach various shapes to the wallpaper.

The embodiment is intended to form a velcro layer of a hook or loop structure provided on the front surface of wallpaper or medium according to an inserting type molding method.

Further, the velcro wallpaper according to the embodiment is intended to be formed by fastening a velcro layer of a hook or loop structure provided on the front surface of a wallpaper or an intermediary body in a one-stop type injection molding.

According to the embodiment,

wall; A first Velcro layer having a loop or hook structure provided on the wall;

A second Velcro layer of a hook or loop structure corresponding to said first Velcro layer; And

A wallpaper provided on a back surface of the second Velcro layer,

Wherein a hook or loop structure in the second velcro layer is formed on the front surface of the wallpaper,

In the molding process for the wallpaper, the upper mold 100a is placed on the front surface of the velcro end forming portion 111a of the lower mold 100a, and the upper mold 100b is fixed to the lower mold 100b through the velcro end insertion hole forming portion 111b. A hook or loop structure of the second velcro layer is formed at a predetermined position of the wallpaper so as to be inserting into the velcro step forming part.

Further, in the method of manufacturing a velcro wallpaper according to the embodiment,

Forming an upper mold including a lower mold including a velcro end forming part formed on a front surface of a wall or a vehicle and a velcro end insertion hole forming part corresponding to the velcro end forming part;

Performing inserting of a hook or looped Velcro onto the velcro end of the lower mold;

Feeding a predetermined material for forming a wallpaper or medium formed on the front surface of the hook or loop structure velcro to a supply portion including a hopper; And

Performing injection of the predetermined material melted in the heating cylinder between the lower mold and the upper mold through a propellant including a screw to complete a velcro inserting type wallpaper or medium; .

The velcro wallpaper according to the present invention can easily adhere wallpaper or facilitate change or replacement of wallpaper pattern.

In addition, the velcro wallpaper according to the present invention may be formed by forming a hook or looped velcro layer on the entire surface of a wall paper or a mediator to facilitate changing or replacing the wallpaper pattern or attaching and detaching various shapes to wallpaper.

In addition, the velcro wallpaper according to the embodiment can be formed by fixing a hook or loop type Velcro layer provided on the front surface of wallpaper or medium in one-stop method during injection molding, thereby shortening the production time.
