Description

Plastic substitute containing fragrance and its manufacturing method {Replacement Of Plastic With Aromatic And Fabricating Method Thereof}

The present invention relates to a plastic substitute and a method for manufacturing the same, and more particularly, to a plastic substitute having excellent degradability and aromaticity and a method for producing the same.

In general, plastic molded articles formed of polyethylene, polypropylene, etc. have excellent mechanical, thermal, and chemical properties, and thus, in the form of containers, wrapping paper, sheets, films, foams, and the like, general merchandise, home appliances, packaging materials, industrial articles, and agricultural products. It is widely used in many applications such as materials. Environmental hormones harmful to the human body are inherent in these plastic molded articles. Environmental hormone is a generic term for a substance that enters an animal or a human body and interferes with or disrupts the action of the hormone. It is scientifically referred to as an endocrine disruptor. Environmental hormones are similar to biological hormones because they act in the body as if they were natural hormones. When these environmental hormones enter the human body, they cause fatal problems for human health, such as abnormal reproductive function, disruption of sexual ratio balance, imbalance of hormone secretion, impaired immune function, increased breast cancer or prostate cancer. Accordingly, the use of substances that can generate environmental hormones is reduced, and currently, countries around the world legally prohibit the use of substances that generate environmental hormones for certain household molded products, especially baby products.

In addition, most of the various household goods, construction materials, and packaging materials that are currently used are manufactured using wood, steel, plastics, etc., and these products have a great problem in post-processing, that is, disposal after the end of their useful life. have. In particular, when molded plastic wastes of various plastic materials are left in the natural world, since their original form is maintained without decay for decades to hundreds of years, serious problems related to waste disposal are generated. In particular, when these molded product wastes are removed by the incineration method, there is a problem that not only emits air pollutants but also generates carcinogens such as dioxin in the natural world, thereby viciously endangering human health.

Therefore, unlike the conventional molded article, the appearance of a molded article made of a new substitute material that can solve the problems caused by the generation of environmental hormones and the waste treatment is particularly required, and many studies and investments for this in progress in each country.

Degradable moldings are made by microbial biosynthesis, such as poly (β-hydroxyalkanoate) s [PHAs], which are decomposed by natural light with the addition of photosensitive reagents. It can be divided into biodegradable resins in which starch and the like are added to synthetic resins such as biodegradable resins, polyethylene, and polypropylene.

However, such photodegradable resins, biodegradable resins and biodegradable resins are not easily decomposed and have high manufacturing costs. Accordingly, there is a problem in that the degradable molded articles formed therefrom are not commercialized.

Accordingly, an object of the present invention relates to a plastic substitute having excellent degradability and at the same time having a directionality and a method of manufacturing the same.

1 is a flow chart showing a method of manufacturing a plastic substitute according to the present invention.

2a to 2d are flow charts illustrating various molding methods of the plastic substitute shown in FIG.

In order to achieve the above object, the plastic substitute according to the present invention is 15 to 65% starch, 3 to 15% polyalcohol (Polyalcohol), 3 to 20% ethylene acrylate copolymer (Etylene acrylate copolymer) and , 8 to 12% salt additives, 0 to 10% plant powder, 8 to 60% polyoliphene resin, 0.2 to 40% fragrance, and 0 to 5% other adjuvants It is done.

The plastic substitute is characterized in that any one of agricultural mulching film, packaging vinyl, plates, food containers, beverage cups, pots, knives, forks, chopsticks, toys, automobiles and industrial air filters.

In order to achieve the above object, the manufacturing method of the plastic substitute according to the present invention comprises the steps of mixing the powder material, liquid material and polymer material, extruding the mixed materials to form a mixture in the form of particulates, and molding the mixture Characterized in that it comprises a step.

The plastic substitute is characterized in that it is made of any one of a brow molding method, injection molding method, sheet injection method and extrusion molding method.

The manufacturing method of the plastic substitute is characterized in that the powder material and the liquid material is mixed, and then the polymer material is mixed with the mixture separately.

Other objects and features of the present invention in addition to the above objects will become apparent from the description of the embodiments with reference to the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 1 to 2D.

The composition of the plastic substitute according to the present invention is 15 to 65% starch, 3 to 15% polyalcohol, 3 to 20% ethylene acrylate copolymer, 8 to 12% It is composed of salt additives, 0-10% plant powder, 8-60% polyolefin resin, 0.2-40% fragrance, 0-5% other auxiliaries.

Starch is formed from corn starch, sweet potato starch, potato starch, cassava (Wood Powder) starch, wheat and legume starch and their modified starches. The starch has a particle size of 100 µm or more and a water content of 12% or less.

Polyalcohol (Polyalcohol) serves to promote the compatibility between the components of the plastic substitute. In particular, polyalcohol improves the compatibility of each component with the polyolefin resin, thereby improving biodegradability and processability. This polyalcohol is a low molecular weight (molecular weight <400) condensate of ethylene glycol, diglycol, propylene glycol, propylene glycol, sorbitol, or sorbitol, pentaerythritol ) Or incomplete esterifications of long chain fatty acids, ie single steric acid, esters and the like. These polyalcohols may be used alone or in combination of two or more thereof. Preferably, 2 or more types are combined and used.

Salt additives not only improve the stability, gloss and cost reduction of the product dimensions, but also serve to promote the biodegradability of the product. The salt additives include alkyl sulfonates, organic acid molysites, polyhydroxy butyrates, steric salts (calcium (Ca), magnesium (Mg), zinc (Zn), barium (Ba), cesium (Ce)). And stearic acid salts of iron (Fe)), calcium carbonate, calcium hydrogen carbonate, hard calcium carbonate or crustacean. Preferably, steric acid salts of calcium (Ca), zinc (Zn) and iron (Fe) are used. These salt additives are used alone or in combination of two or more. Preferably, it mixes and uses 2 types.

Plant powder is used wood powder, poncho powder or sugar cane powder, and the like, preferably wood powder.

The polyolefin resin is to use a metal-free polyolefin resin made of a metal-free catalyst. For example, low density polyethylene (LDPE), high density polyethylene (HDPE), linear low density polyethylene (LLDPE), etc., which are homogeneous polymers and hybrid polymers of ethylene, are used.

Metal-free polyolefin resins have a relatively narrow molecular weight and molecular composition distribution, and have excellent performance in localization distribution. In addition, the polyolefin resin has characteristics of high impact strength, high burst strength, stress cracking, and high transparency.

In addition, since the metal-free polyolefin resin has a relatively low melting point and the initial heat sealing temperature is relatively low at about 102 to 125 ° C., the low temperature heat sealing property of the vinyl product is improved, and the processing speed is improved. In other words, the use of polyolefin resin in starch without tensile strength improves tensile strength, stress cracking, impact resistance and burst resistance.

In addition, the metal-free polyolefin resin can contain a relatively large amount of starch and its auxiliary compound because the inclusion of the starch excellent in degradability. Accordingly, the degradability of the product can be improved and environmental pollution can be lowered.

The fragrance has a mental stabilizing effect, a soothing effect and an insect repellent effect, which plays a role in dissipating the scent in the finished plastic substitute. This fragrance uses various flowers such as pine, deodeok, injin mugwort, acacia, chrysanthemum, fruit juice powder such as lemon, apple, grape, melon, and other natural flavors such as other natural plants.

Other adjuvants serve to prevent and inhibit starch, its orientation aid and resin mixture from being degraded relatively quickly due to light, heat, acid microorganisms or bacteria during processing or use. These other auxiliaries use antioxidants, light stabilizers, antifoam agents, anti-combustion agents, antistatic agents, contingencies, foaming agents, colorants, and lubricants, depending on the characteristics of the product. For example, when plastic substitutes are made into foam products, the plastic substitutes add urea, water and fatty hydrocarbons, which are blowing agents, to the composition.

A method of manufacturing a plastic substitute having such a composition will be described with reference to FIG. 1.

1 is a view showing a method of manufacturing a plastic substitute according to the present invention, the method of manufacturing a plastic substitute according to the present invention is the first and second mixing step (S1, S2), extrusion process (S3), cooling step (S4) ) And the molding step (S5).

In the first mixing step (S1), starch, polyalcohol, other adjuvants and fragrances which are liquid components are mixed using a mixer. At this time, the mixing temperature is 50 ~ 60 ℃, the mixing time proceeds to about 10-15 minutes.

In the second mixing step S2, the remaining compositions except for the composition of the starch and the liquid component are mixed.

Separately proceeding first and second mixing processes (S1, S2) may simultaneously mix the starch, the alignment material, some polymer resin material and the fragrance.

In the extrusion process (S3), the mixture mixed in the first and second mixing processes (S1, S2) is put in the powder feeder and the particle feeder so that the ratio of length to outer diameter is 44-48: 1, and the rotation speed of the screw is maximum. 900 ~ 1200 revolutions / minute, step by step temperature of each location is 90 ~ 125 ℃, 115 ~ 145 ℃, 130 ~ 170 ℃, 110 ~ 140 ℃, 105 ~ 155 ℃ extruded in a double screw extruder to form fine particles .

In the cooling step S4, the extruded mixture is cooled to a predetermined temperature and then cut to form a particulate plastic substitute.

In the molding process (S5), the plastic substitute in the form of fine particles is formed into a plastic product using a brow molding method, an extrusion method, or an injection method as shown in FIGS. 2A to 2D.

As shown in FIG. 2A, the brow molding method is color-printed after brow molding the plastic substitute in the form of fine particles. (S11, S12) Vinyl printed materials, such as agricultural mulching film or packaging vinyl, are produced by producing the color-printed plastic substitute. (S13)

As shown in Figure 2b, the extrusion method is a sheet injection of the plastic substitute of the fine particles and then mixed with the non-foaming material. (S21, S22) Then, color printing on the plastic substitute molded by the molding process, such as a drinking cup It forms cups of (S23, S24).

As shown in Fig. 2c, the foam sheet injection method mixes the foaming material after sheet injection of a plastic substitute of fine particles. (S31, S32) Then, the plastic substitute is molded to form a tableware material such as a plate. (S33)

As shown in Figure 2d, the injection method is to injection-molded plastic substitutes of fine particles to form a knife, fork, chopsticks, flower pots, toys, automobiles and industrial air filters (S41).

The plastic substitute according to the present invention and a method for producing the same can obtain the fragrance effect in the molded article by adding a fragrance. In addition, it is possible to obtain a physical and mechanical strength of the plastic substitute due to the metal-free polyoliphene can greatly increase the content of easily decomposed components in the plastic substitute.

Such a plastic substitute according to the present invention and its manufacturing method will be described in more detail with reference to the following examples. The scope of the present invention is not limited to the examples described below.

Example 1

Agricultural Mulching Film

Starch, sorbitol (Sorbitol), glycerin, epoxy soybean oil, oleic acid, steric acid zinc, steric acid calcium, 1010, UV-531, DSTP and ultra-precision carbon black shown in the table above It is placed in a material mixer to form a first mixture. At this time, heating temperature is 50-60 degreeC, and mixing time is about 15 minutes. Separately, EAA and metal-free polyethylene are put in a particle material mixer in the same mixing state to form a second mixture.

The first and second mixtures are each fed from a powder feeder and a particle feeder of a double screw extruder having a length: outer diameter = 44-48: 1 to a double screw extruder to form a particulate plastic substitute made by extrusion. At this time, the rotational speed of the double screw is 380 ~ 410rpm, step temperature of each position is 145 ℃, 155 ℃, 165 ℃, 160 ℃, 150 ℃, 155 ℃, respectively, the vacuum degree is 0.6MPa.

The particle index of these particulate plastic substitutes has a MI of 2.3, a density of 1.08 g / cm 3 and a moisture of 0.8%. In the case of thin film indicators, the tensile strength (horizontal / vertical) is 26 MPa / 21 MPa, the adiabatic stretching ratio (horizontal / vertical) is 650% / 480%, and the perpendicular tear strength (horizontal / vertical) is 90N / 110N.

The particulate plastic substitute is formed into an agricultural mulching film through a cooling process and a molding process.

After covering the mulching film on the crop, the film begins to split after passing the stabilization period (about 65 to 75 days), and then widely divided after 15 to 20 days. Thereafter, pulverization / powdering (120-180 days) appears, some of which turn into extremely fine powders, and others of which turn into water (H ₂ O) and carbon dioxide (CO ₂ ), which undergo continuous decomposition for one year. Accordingly, after a predetermined period of time, the agricultural mulching film is decomposed and disappeared.
