Description

Composition of writing utensils and craters erased with an eraser (crayons, colored pencils, colored pencil pencil core)

The present invention relates to crayons, colored pencils, such as craters and writing instruments such as color sharp pencils, and more specifically, unlike conventional crayons and colored pencils, the surface is densely applied when painted on paper without bubbles. It is so thick that it is painted like paint, and the painted part is not stained on the other side like crayon, it does not get on the hand when touched, and the composition is hard, so that the strength is so strong that it cannot be broken by the force of the hand held by the composition. After painting and scratching with a fingernail does not come out on the nail, and erased with a rubber eraser for graphite pencil stationery and relates to the composition of the writing instruments and writing instruments that are erased and erased from the paper.

Until now, coloring materials such as colored pencil crayon crayons are not densely painted on paper like watercolor paints, but the bubble phenomenon (a glimpse of paper in the paper area painted on paper) occurs severely, and the paper is peeped even after several times. In the state

If you erase with a rubber eraser for stationery, it will not be completely erased, but rather will spread around and become very messy. In addition, the storage of paintings or documents painted with these coloring materials will cause the coloring material to be deposited on other papers that come into contact with the colored papers. Therefore, the present inventors have repeatedly conducted various experiments, such as rubber pigments (pigments or dyes) for plastic cosmetics, plastic melters, plasticizers, dispersants, coloring aids, optical illusion inducers (light emitting agents), and heat stabilizers that are generally distributed. In the production using the extrusion method of the conventional method using the (including fragrance), the erasable composition of the present invention is possible, even if possible (1. smoothly painted while meeting the characteristics that must be hard, 2. painted without bubbles Close to, dense and sharply applied, 3. dense and vividly applied, 4. unspoiled after being applied, 5. cleared). To purchase pigments and randomly processed raw materials by separate order The manufacturing method devised by the inventor for the present invention which is a processing method of furnace ((1. Porous inorganic production method. 2. Pigment (dye) and fineness (ultra fine powder) control processing method of porous inorganic material. Manufacturing method to coat pigment (pigment, dye) on the porous inorganic material manufactured by the manufacturing method, 4. Master batch or pallet manufacturing method, 5. Pencil-based flavor bonding manufacturing method) to satisfy marketability On the contrary, when the components of the composition of the present invention are mixed with a general compounding machine and produced by a general extrusion method, the colored pencils may be erased, but they may not have a product value at all, and they may not be densely painted even if they are placed on the market. I know it doesn't sell in the market because it doesn't get too thick and doesn't paint too hard. It became.

Conventional colored pencil technology

Conventional crayon colored pencils are made by using paraffin resin in a pigment with a large amount of wheeler, kneading with carnauba wax, wax, hardened oil, stearic acid and other colorants, heating, melting, pouring into a mold and cooling.

Such coloring materials contain a large amount of fat- or oil-resin resin and do not care about the miniaturization of pigments, and even if they are miniaturized, the milk fat does not appear densely packed into a colorant (wheeler) and is erased with a rubber eraser. If you mix a lot of wheels for back strength adjustment, it will not be painted well. If you put less, the cutting strength is too weak to be a product. It is also a disadvantage of conventional products that are buried on the other side of the used paper is not easy to store and buried in the hand, and that one side of the paper will be damaged if one function is good.

Challenges to be determined by invention

Therefore, until now, colored pencil crayons have not been able to invent the technology intended by the present inventors because of the characteristics of commercially available raw materials and ingredients, and the stereotype that the role of a given machine does not exceed a certain limit. As described above, the present inventors also felt frustrated because they could not be differentiated from conventional colored pencils by hitting the wall of stereotypes due to the state of pigments that are mass-produced on the market and the mechanical facilities given to reality. Products made of existing facilities and existing ingredients of the product could be erased, but they are barely painted by pressing firmly and the colors are faintly applied, but the colors are so light that they are painted rather than scratched. Level, and if you paint in double, the first color Naohmyeonseo kkakyeo summed vaguely seven eh More Everyday color faded and blotchy (shit), the purpose of the erased itself is made eoteuna was hardly lead to the conclusion that goods be impossible. At the time, I had to go through the process of giving up a lot of times, but with persistence, I studied the manufacturing method and experimented variously with the material obtained by random order in the facility. As a result of completing and painting the present invention, the inventors have obtained a result that can satisfy the intended purpose.

Detailed description of the manufacturing method

Method 1: Description of manufacturing method of porous inorganic material

The composition of the colored pencil that is erased in the course of studying the present invention is so thick that it does not cause poo 2 to 3 times higher than the pigment for the purpose of obtaining a thick effect even if only one problem is not applied when painted on paper. However, it is a work to artificially improve the porous inorganic material for coating with molten resin after inserting the pigment into the micropores (circles) by making the shape of the particles porous with C or S shape.

Device structure description: Electric, gas, petroleum, petroleum gas, which has opening and closing device with diameter of 2mm in the furnace (metal furnace that can withstand the temperature to heat and melt inorganic matter) suitable for the capacity to be manufactured In order to increase productivity, it is equipped with a plurality of melt discharge pipes, and a mesh conveyor conveyor system with a diameter of 1mm is installed at the lower end of the system, and guide rails are installed on both sides of the melt so that the melt does not overflow out of the mesh. When the water comes out, the cooling water is installed in the shape of a tank so that it can be immediately cooled. The water is sprayed into a thin balloon, and the minerals are blown out and cooled in the cooling water to become porous inorganics. Separated and pulled into buckets in the purpose and the mineralized minerals are loaded onto the conveyor It is collecting and fall into a collection vessel at the bottom.

In this process, 2mm pipe melt is discharged and the opening is opened by connecting a high-pressure air tank and a pipe by drilling a hole at the end of 5cm. In this regard, the melt is molten but stiff and loads the melt into a 2mm discharge pipe. Pipes connect air tanks and furnaces to prevent them from being discharged alone. At this time, it should be noted that the pressure automatic control device is attached to the switch of the high-pressure tank, so that the furnace loses its inherent strength due to heating and is weakened, so it is safe to control the air pressure to around 15 kilolbs. The switch is a device that can be manually adjusted to ensure that the flow of the melt and the foaming state is optimally porous.

2nd manufacturing method: Description of the fineness control processing method (Liposome) of inorganic substances and pigments

Pigments and dyes are generally produced and distributed in volume particles having a density of about 250 mash. The composition of the present invention has to be finely pigmented to overcome the fact that the characteristics of the colored pencils of the existing craters and writing instruments are not densely applied like paints, and the dye is dissolved in an aqueous solution like an aqueous oil. The finest molecules are known, but the main composition is a solid resin that is used as a base material, so it does not dissolve or automatically dilute, so it is blended into the resin as particles at the time of blowing. If it is not mixed with more than 1,000 mash, it is essential for the purpose of obtaining a dense effect like paint, and also to facilitate the insertion of a gap into the porous inorganic material having a transparency of 250 mash. In this process, the purpose of controlling the fineness of the porous inorganic material is intended to have a larger volume volume of the inorganic material than the pigment.

Third Manufacturing Method: Description of manufacturing method for coating pigment on porous inorganics

In the selection of a colorant, it is difficult to obtain a vivid color due to deterioration effect due to the heating temperature or in the case of an inorganic pigment, so when the powder and lubricity colorant are made, both the dark side sharpness of the color and the dense applicability can be erased. Because it is difficult to use both, no color, base pigments together, it does not satisfy both the vividness and the darkness of the color, dye can solve this problem. However, dyes are unstable pigments that have excellent transferability and discoloration properties and dissolve on paper if they have a little moisture or moisture. Therefore, dyes should be inserted into the micropore of the minerals and coated to prevent them. You have to go through this process.

In the manufacturing process, the inorganic material and the dye are mixed in a non-melting heat high-speed stirrer (mixer), and then in the process of blending the three-dimensional silicon with the mineral molding saturated with the pigment during the second crosslinking, the mixture is stirred with a heat of fusion of 80 to 150 ° C. do. At this time, it may be stirred with high density polyethylene (LDPE).

Fourth Manufacturing Method: Mastering Method or Manufacturing Method to Palletize

After mixing the pigment + resin + coloring aid (dye coated with microorganisms) + plasticizer + dispersant + heat stabilizer evenly in the cost of fusing heat, (1) at a temperature having a heat of resin melting at 150 ° C. in a kneader (stirrer) 100% evenly melt-dispersed formulations are made into master batches (pallets) and (2) molded by extrusion or press molding or injection molds of the required thickness. (3) In case of manufacturing sharp pencil (0.5mm, 1mm) at this time, mix 1,000 ~ 2,000 mash powder of inorganic material by color preparation pencil, color pencil, crayon and so on. do.

5th Manufacturing Method: Flavor Bonding Method

Purpose: When the fragrance is blended into the formulations completed by the above four manufacturing methods by the fourth method, the inherent properties of the fragrance (the compounding wheeler changes inherent properties depending on acidity, alkalinity and heat) It is difficult to obtain the inherent physical properties of colored pencils because the seam is molded and bonded to the wall of the seam when there is a little heat in the middle of the cooling process. In the final extruded mold of the shim extruder, three-holes are made in the pipe immediately before the pipe cooling device exiting the mold extruder, and the fragrance is blown into the air and joined (see pneumatic spray coating method) to cool the pipe with some temperature and the remaining cooling passage. In the process of passing, the method of joining by forced pressure friction has no effect on color.

In the present composition, the pigments (pigments and dyes) is a pigment that does not have a property of being stained with paper that prevents the human body from being harmless, discolored, and discolored. It is relatively broad in color only when inorganic, organic, and basic are used together. The particle size of these particles is more than 1,000 mesh ultra fine particles, the denser the paint surface, the denser it is, the better it is dispersed in a high-performance grinder such as a three-roller ball mill. Here, the dye is a color that is strong in color and has the most dense effect, and is a highly stable unstable pigment. It is dissolved at room temperature in water, which prevents it from penetrating and erasing into paper. Therefore, the particle size of artificial inorganic porous particles other than high-density polyethylene resin is prevented. Four times the space of the dye is processed into particles, the dye is inserted into the pores, and then coated with three-dimensional silicon can be more dense and dense to obtain a color close to the paint.

Auxiliary explanation for the above technology

The resin in the composition is the erased main material of the present invention. In general, the solid plastic resin is hard and has a high cutting strength. It is applied to the most dense resin, which is the most dense resin, and the colorless appearance of the particle, that is, the linear structure of the molecular structure is the shortest linear form. If only the plasticizer is added to it, it can be seen that high density than low density does not cause swelling, and it cuts cleanly and is densely painted on paper. Therefore, the choice of resin meets the task of erasing the problem of the present invention, and more importantly, all inventions can be commercially applied to the industrial field only if they are excellent in practicality and commerciality in daily life. It is most suitable as the main component of colored pencils that are erased by high density polyethylene (HDPE) in order to meet the task of dissolving in water and causing delamination when recycled in water without dung. It can be said.

The plasticizer in the present composition is added to impart ductility to the synthetic resin, and its blending amount is determined according to the type and blending amount of the resin used. For example, in the case of high density polyethylene, it is preferable to use a larger amount than in the case of low density polyethylene. As an example of a plasticizer suitable for use in the present composition, mineral oil is most suitable according to the JIS S6026 hazardous substance control method among those listed above.

The amount of usage varies depending on the case of colored pencils, crayons, and color pencils (0.5 to 2.0mm) for high density polyethylene.For sharp pencils, the minimum amount of plasticizer should be used in addition to inorganic fillers and dispersants. In this chapter, maximum color pencils are used as long as they do not impede physical properties.

Dispersants, also called lubricants, are formulated into the composition to ensure that the components are evenly dispersed. Examples include the types described above, and the selection of the most suitable component is a metal soap with a fine powder of at least 1,000 mesh. This dispersant has a high melting point crushed into ultra fine particles as much as possible when the sharp core (0.5 ~ 1.0 mm fine pencil core) is produced in addition to the purpose of dispersing. Or metal powder must be added and it is 2 times more weight than crayon manufacturing.

Color Inducing Agent (Fluorescent Agent): This fluorescent agent is a raw material generally used in highlighter pens, and it is not intended to make a fluorescent pencil because it is a raw material used in a highlighter pen. When the finished product is manufactured by the above manufacturing method without the addition of a fluorescent agent, it is very dense and thicker than the existing product, and is almost similar to that of the paint, but when viewed in detail, it can be felt as a small powder and can be clearly distinguished from the paint. It is formulated in small amounts to take advantage of optical illusions (spasparc) in order to look more dense and dense, like more paint. In the case of fluorescent writing instruments, the eye is tired due to eye disturbance when used for a long time, and the optical bubble that is visually felt in the state of being painted with this composition (the phenomenon of paper seeing) is a little optical illusion It is suitable to use 0.01 parts by weight of a pigment and a resin composition ratio proportional fluorescent agent because it appears to be painted even if it is produced.

As described above, by making a porous inorganic material having a particle size of 250 to 450 mesh by the first manufacturing method, diluting it with 3D silicon, and putting the dye therein into a high speed screw mixer without heat, the silicon is bonded to the microporous inorganic material. In the dye, due to the aqueous nature of the silicone, some of the dye is coated on the outer wall of the inorganic material and the dye is not completely dissolved due to the lack of the silicone solution is solidified and solidified with the centrifugal force and friction of the high-speed screw, It is pushed in and the continuous rotation gives the coating effect during the friction heat. The primary processed packed pigment processed material, that is, the colorant (the above-mentioned B) is mixed with 30 parts by weight of a total of 70 parts by weight of a + b + c + d + e + f of A to be sufficiently dispersed in a kneader, and then, plastic When molding a compound pellet manufacturing system or pencil lead into a press machine, it is molded on a sheet forming machine, and when molding a pencil lead by injection or extrusion, a kneading extruder or a double Molded into a twin extruder to make a masterbatch.

In the process of flavor bonding, in the case of forming a pencil lead by pressing, a small amount of perfume is inserted into the tip of the core opposite to the portion to be painted of the pencil lead, and in the case of extrusion, the perfume bonding is performed by the fifth manufacturing method.

Colored pencils (core diameter of 2 to 7 mm), crayons, and color sharp pencils (0.3 to 1.0 mm) produced by the method described above are completely coated without bubbles when they are painted on various paper materials, do not appear buried, and are thickened with rubber erasers. If you erase it, it will fall off cleanly, and in particular, the paper painted with colored pencils according to the present invention soaked in water can be easily released and recycled. As such, when the colored pencil crayon color sharp pencil composition of the present invention is used, various effects and advantages that cannot be achieved by the existing colored pencil, crayon, and color sharp pencil can be obtained. Advantages and other features of the present invention will become more apparent from the following non-limiting examples.

<< Example >>

Hereinafter, the present invention will be described in detail with reference to Examples.

<< Example 1 >>

As an example of the preparation of the erased colored pencils, the product of the colored pencils, which is intermediate between the crayons and the sharp colored pencils, which are commonly referred to according to the size and use of the area of the painted cores, was found to be the most suitable formulation.

If the contact area of the seam is wide like crayons, the properties of the seam should be soft. If the cutting area of the seam is narrow like sharp, the pigment will be concentrated on the small circle of sharp seam where the finger presses for cutting. The color pencil is a medium concept, so it looks dark even if it is not dark. Therefore, it is optimal to mix the dark, dense, painted face and erase it without smearing on the hand. The compound can be molded with an automatic extruder to increase productivity and reduce costs.

<< Example 2 >>

In this experiment, in order to avoid the characteristics of the paper being rubbed with the seam and paper like the crayons, the resin is not easily densely painted. First, the resin is added in small weight% and the plasticizer is added to make the cutting strength weak. In addition, unlike colored pencils and sharps, dyes were added to optimize the color smoothly and smoothly. It is painted well even with less effort, but it does not get scratched, so it gets erased well, but as time goes by, the transferability of the dye tends to be adsorbed on the paper. If it is not corrected, it is stored almost as it is. It is rare to modify it after several days or a certain time. And if the humidity or temperature change is not severe, the color paper adsorption phenomenon due to the transition phenomenon was not found until several days. This compound should be molded by press mold.

<< Example 3 >>

This experimental formulation is a blending example for producing a thin pencil (commonly known as a color sharp pencil) for writing instruments.

Unlike colored pencil crayons, when the core was thin and molded into a blend of colored pencils (Example 1) with a diameter of 0.3 to 2.0 mm, the tip was bent to obtain a result that cannot be used as a sharp pencil lead. Since the composition is so weak that it does not become sharp at all, it bends or crumbles, and thus it is a stone powder with a high heat of fusion, so it retains its mold even when melted and blended. The compounding ratio of was increased in a relatively large amount. It is economical for this compound to be molded by a press die.

The above composition was extruded or press-molded the compound formed by the method of the manufacturing method 1, 2, 3, 4, 5, the inventors arbitrarily intended to prepare a shim of 6mm diameter 170mm long and 0.5mm diameter 50mm standard.

General crayons and colored pencils of the same standard purchased from commercially available crayon colored pencils and sharp pencils and sharp pencil cores made of graphite are characterized by the following physical properties, adhesion coating properties, transition properties, peelability by a rubber eraser, and composition according to a high magnification electron microscope. The surface arrival color of the paper was also tested for density and density. The test results are as follows.

* burglar ; This product is 5 ~ 10 times harder than ordinary colored pencils and crayons, and sharp pencils are elastic and bent like bending, unlike general products.

* Wear: The service life of this product is more than 10 times longer than the colored pencils and crayons of the general product, and the sharp pencil has more than 3 times longer life than the graphite pencil.

* Adhesive coating property: When scratched with a knife after application, ordinary crayons are severely scratched from the Joey, and ordinary colored pencils are scratched a little less, but this product is not peeled off, and sharp pencils have no big difference but when rubbed with sweaty hands Graphite pencil smeared, but this product did not smear.

* Transition: When rub the coated paper with your hands and other papers, crayons, colored pencils and graphite pencils are all stained with your hands and paper, but this product is not stained at all. Even if you touch the product itself with your fingers, the crayons are badly stained, but they are not washed well in water, and the colored pencils are only slightly stained compared to the crayons.

* Peelability by water: The crayon colored pencils of general products are smeared on paper when they are soaked in water and do not peel off because the color is soaked on the paper, but this product falls off and recycles with high-quality paper or has less discoloration ratio when paper is recycled. Could.

* Peelability by rubber eraser: When the color painted on paper is rubbed with graphite pencil rubber eraser for general stationery, the crayon is not erased but the smudge is smeared and the colored pencil is about 50% peeled off a little, but the color is soaked on paper. It is not erased anymore after remaining, but this product comes off easily easily.
