A variety of paper fabric products can be manufactured in one manufacturing device through a combination of the sprayed ingredients and whether or not the transfer paper is attached. At this time, by using a release agent or adhesive that has excellent water dissociation properties, not only can the paper tape be easily repulped from the paper fabric product without removing it, but also a paper tape of excellent quality can be produced by eliminating foreign substances or lumps. In particular, when manufacturing the aqueous release agent and the aqueous adhesive, the concentration can be adjusted using distilled water, so the desired peeling force can be adjusted according to the purpose of use of the paper tape.

Description

Comprehensive manufacturing equipment for paper fabric products {COMPLEX MANUFACTURING APPARATUS FOR PAPER FABRIC}

The present invention relates to a comprehensive manufacturing device for paper fabric products. More specifically, the present invention relates to a comprehensive manufacturing device for paper fabric products. More specifically, two coating devices each equipped with a dryer apply ink, resin, or water-based adhesive to one side of the base paper, dry it, and apply a slot die to the other side of the base paper. By applying a water-based adhesive and drying it, and supplying additional paper as needed to attach it as a whole, it is possible to produce a variety of tape-type paper fabric products in small quantities. At this time, by using the water-based release paper and water-based adhesive that have excellent water dissociation properties, the paper tape can be dissociated from the paper fabric product without separating the paper tape used in the paper fabric product such as a paper box, thereby increasing the recycling rate of paper. It was made to exist.

Paper tape, a representative tape-type paper fabric product, is not only easy to tear and use by hand, but can also be produced in an eco-friendly manner, so it is used in a variety of ways, such as when assembling boxes. These paper tapes are manufactured using various manufacturing methods, as shown in (Patent Document 1) to (Patent Document 3) below, so that they do not easily come off or peel off from the adhesive surface when used and can maintain adhesive performance firmly even in external environments.

This relates to a method of manufacturing paper tape with improved adhesion. The upper and lower rollers between the three vertical rollers are made of wool paper rollers, and the middle roller is a metal roller. The heating temperature is 100~150℃ and the tape is heated to 10~15kg. A compression processing process that pressurizes the substrate to /inch2; A pretreatment process of coating the substrate that has undergone the pressing process with a water-soluble polymer resin; A backside treatment process of applying solvent-free silicone to the backside of the substrate that has undergone the pretreatment process; An application process of applying an adhesive to the surface of the substrate that has undergone the back surface treatment process; a drying process of heating the applied adhesive to adhere to the substrate; It consists of a winding process of winding the dried substrate. In the pressing process, the voids formed in the paper are pressed to close, so that the adhesive applied to the surface of the paper penetrates into the inside of the paper, and the amount of adhesive attached to the surface increases. It increases the adhesive strength of the paper tape by preventing it from shrinking, and by pressurizing the paper, the strength of the paper increases, improving the wear resistance and elongation of the paper tape, maintaining the smoothness of the paper surface in a good state, and making it a water-soluble acrylic product that can be recycled. By using an adhesive, etc., it is easy to regenerate during recycling, and the adhesive strength of the adhesive is prevented from deteriorating over time.

The aim is to provide a method of manufacturing eco-friendly paper tape with water-retaining properties that are highly recyclable and environmentally friendly. After applying water-based silicone, which has mold release properties, to the entire surface of one side of this paper-based base paper, hot air at 130°C is sprayed at a speed of 30 m per minute to form a water-based silicone film on the surface while drying, and the water-based silicone film is formed on the surface. A water-soluble adhesive with water-soluble properties is applied to the opposite side of the silicone film, and then dried by spraying hot air at 130°C at a speed of 30 m per minute to form a water-soluble first adhesive film protected by release paper on the surface. On the surface of the silicone film, which is the opposite side of the first adhesive film, a water-soluble second adhesive film is laminated in the form of a band at regular intervals over the entire length of the base paper. As a result, it is possible to reduce environmental pollution by allowing it to be recycled as old paper when used as a packaging material for products, and when used for industrial purposes such as paper-and-pencil connection at paper companies, automatic connection can be made without slowing down the speed (1300M/Min). It has characteristics that allow it to exist.

Otherwise, if no impurities other than the pulp are contained and the pulp does not exhibit stickiness, it can be evaluated as alkaline dissociation or alkali dispersibility.

(Compare soot)

On the other hand, as shown in [FIG. 8], as a result of comparing the degree of soot generated by burning the Example and the Comparative Example, almost no soot was generated in the Example as shown in (a), but Comparative Example 1(b) and Comparative Example In 2(c), it can be seen that soot is generated. Therefore, it can be seen that the example is a paper tape that is harmless to the human body.

(heat resistance test)

The heat resistance test compared the physical properties of the Examples according to the present invention and Comparative Example 1 using hot melt when exposed to 70°C for 24 hours and when exposed to 105°C for 3 hours. As a result, as shown in [FIG. 9], there was little change in Example 1 even at 105°C, but in Example 1, the physical properties of the adhesive surface changed at 105°C and the adhesive strength decreased. Therefore, it can be seen that the present invention has excellent heat resistance compared to the comparative example.
