Abstract

PURPOSE: Provided is a method for manufacturing a pyroligneous liquid-containing sheet having far infrared ray- and anion-emitting effect, electron wave protectability, and antibacterial and deodorizing effects, without adversely affecting the physical properties of polyurethane. CONSTITUTION: The method for manufacturing a pyroligneous liquid-containing sheet comprises the steps of: ejecting a predetermined amount of polyol contained in a polyol tank(10) to a mixing tank(30); ejecting a predetermined amount of isocyanate contained in an isocyanate tank(20) to the mixing tank(30); ejecting a predetermined amount of wood vinegar contained in a pyroligneous liquid injector(40) to the mixing tank(30); and introducing the mixture of polyol, isocyanate and pyroligneous liquid contained in the mixing tank(30) into a mold and then foaming the mixture.

Description

Wood manufacturing solution sheet {seat manufacturing method}

The present invention relates to a method for producing a sheet composed of polyurethane foam, comprising a foaming method by injecting a wood solution having antibacterial and odor removing properties into a mold together with polyurethane, The present invention relates to a method for producing a wood vinegar sheet, which emits far-infrared rays and anions that are beneficial to the human body without affecting them, blocks electromagnetic waves, and has excellent antibacterial and odor removal properties.

In general, the sheet is urethane is injected into the mold and foamed, and the urethane is foamed in the mold, so that the sheet can be easily produced in a desired shape.

Polyurethane sheet is foamed by mixing water with a polyol containing a catalyst and then mixed with isocyanate and injected into the mold.

Recently, many products using charcoal have been developed and are being studied to apply it to sheets. Charcoal has excellent antibacterial and odor removal properties, which can suppress bacterial growth such as odors or molds generated in old sheets.

However, since the charcoal absorbs water in the process of blending the charcoal powder into the polyol, the chemical reaction between the polyol and the water is insufficient, and thus the polyurethane sheet cannot be changed and the polyurethane sheet having the desired hardness and buffering property cannot be produced.

Therefore, in the prior art, there was a technical difficulty in making a sheet using charcoal.

The present invention was developed in view of the conventional problems, and an object of the present invention is to mix the wood vinegar generated in the process of making charcoal into a polyol and isocyanate, which is a raw material of polyurethane, and to inject it into a mold to make a sheet of a desired shape. In particular, since the wood vinegar is liquid, it has antimicrobial and odor removal properties, which are charcoal functions, without affecting the physical properties of the polyol, and also has a variety of functions such as physical and mental stability, anion generation, air purification, and electromagnetic wave absorption. In providing.

In order to achieve the above object, the present invention provides a process for quantitatively discharging a polyol in a polyol tank to a mixing tank, a step for quantitatively discharging isocyanate in an isocyanate tank to a mixing tank, and a step for quantitatively discharging the wood vinegar of a wood vinegar injector into the mixing tank. It is made, and the polyol and isocyanate and wood vinegar of the mixing tank is injected into the mold to foam.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a process chart showing a manufacturing process of the sheet of the present invention. The present invention provides a mixing tank having a polyol tank (10) for storing and stirring a polyol which is a raw material of polyurethane, an isocyanate tank (20) for storing and stirring isocyanates and a nozzle (31) for injecting these polyols and isocyanates into a mold ( 30).

The polyol is stored in the polyol tank 10 in admixture with water for chemical reaction.

And the present invention is provided with a wood vinegar injector 40 for storing the wood vinegar. The wood vinegar injector 40 is connected to the mixing tank 30 and allows the wood vinegar to mix together when the polyol and isocyanate are mixed. Since the wood vinegar is a liquid phase does not absorb or denature the catalyst or water required for the chemical reaction of the polyol, it is possible to produce a polyurethane sheet.

The mixing amount of the present invention is polyol 49 ?? 69.9 weight%, isocyanate 29.8 ?? 49% by weight and 0.3% herb liquor ?? 2 wt%.

Wood vinegar is a material that cools and condenses smoke from carbonizing oaks, and about one third of the weight of charcoal is collected. Wood vinegar is excellent in antibacterial and odor removal. Especially, it releases far infrared rays and negative ions to promote metabolism of human body. And it also works to block electromagnetic waves, so it is effective when used on a seating person.

According to the present invention configured as described above, polyol and isocyanate supplied from the polyol tank 10 and the isocyanate tank 20 to the mixing tank 30 are mixed with the wood vinegar of the wood vinegar injector 40 and then injected into the mold through the nozzle 31. do.

The mold is a mold for making sheets, and the injected raw material is foamed and hardened into polyurethane foam. The finished polyurethane foam sheet contains wood vinegar solution, which has antibacterial and odor removal properties.

And since it emits far infrared rays and negative ions, it can be manufactured as a car seat to activate the driver's metabolism to stabilize the mind and body, purify the air inside the car, and remove moldy odors.

As described above, according to the present invention, a urethane is formed by adding wood vinegar to a polyol which is a raw material of polyurethane, thereby forming a sheet having a function unique to wood vinegar.

Since the wood vinegar is a liquid, it does not affect the water required for the chemical reaction of the polyol, so that polyurethane foam can be made, and a sheet having durability and antibacterial and odor removal effects can be produced.
