The Republic of Korea ratified in November 2002 and is classified as a developing country, but has no legal obligations but is under pressure to reduce greenhouse gases along with Mexico as an OECD member.

Korea is expected to be asked to participate in the future as the compulsory countries are concentrated in developing countries in 2013 ~ 2017.In 2002, according to the IEA statistics, Korea's annual CO2 emissions were based on 2000. It is ranked 9th in the world with 134 million tons, accounting for 1.8% of total global emissions. Moreover, since 1990, the emission increase has reached 85.4%, which is the highest increase in the world, which is highly likely to be classified as a mandatory country.

The gases that are being reduced to induce global warming include carbon dioxide (CO ₂ ), methane (CH ₄ ), nitrous oxide (NO ₂ ), carbon fluoride (PFC), hydrofluorocarbon (HFC), sulfur fluoride (SF ₆ ), etc. Six types of bioplastics are currently being applied only to disposable products and some industrialized products such as plants, seaweeds, etc., with the focus on existing biodegradable plastics at a time when low carbon green growth, global warming, and carbon reduction have become a hot topic. Industrialization is rapidly progressing to the category of Bio Based Plastics, which uses carbon neutral biomass-derived raw materials, and is a very important technological advancement in that it is directly applied to finished products and leads to increased sales. It is coming true.

Recently, plastic products using biomass have been developed to prevent environmental pollution. These products contain biomass containing plant powder, etc. Because of this, the degradability was improved to some extent compared to pure synthetic plastic products. The off-flavor problem caused by

Therefore, there is a demand for developing a technology capable of improving decomposability while removing mechanical problems as well as mechanical properties as well as conventional plastic products.

It may be carried out in a different order than described above. That is, each step may be performed in the same order as specified, may be performed substantially simultaneously, or may be performed in the reverse order.

Pellets for producing a plastic product according to an embodiment of the present invention is a polymer resin; Waste paper powder obtained by grinding waste paper into fine powder; glue; Linoleic acid; Maleic acid; Silane coupling agents; And an organic peroxide; after the composition is prepared, the mixture is prepared by mixing and extruding it. The present invention is a pellet that can be used to prepare a plastic product, it can be used to produce a plastic product having the same or similar mechanical properties as the plastic product using conventional synthetic resin pellets. In addition, unlike plastic products manufactured using biomass, odor problems can be minimized, and the use of glue as a binder has an effect of improving degradability.

The polymer resin is not particularly limited, and known polymer resins such as polyethylene terephthalate (PET) resin, polypropylene (PP) resin, and polyethylene (PE) resin can be used. Preferably, polyethylene resin (PE) may be used, and in this case, a high density polyethylene (HDPE) resin, a low density polyethylene (LDPE), or the like may be mixed and used.

The waste paper powder refers to a pulverized waste paper into fine powder. Waste paper is a general paper, and means petroleum-derived resources such as newspapers. Waste paper is preferably adjusted to the size of the fine powder according to the plastic product to be manufactured, for example, it can form a fine powder in the size of 100 to 400 mesh. The present invention can improve the degradability by pulverizing waste paper instead of using only synthetic resin as in the conventional plastic products. On the other hand, the plastic products recently developed using biomass has the advantage that the degradability is improved compared to the plastic products made of conventional synthetic resins, but due to the carbonization phenomenon caused by lignin during the manufacturing process, odor problems occurred. The disadvantage is that the product is not commercially available. However, the present invention also has the effect of minimizing this off-odor problem by replacing the biomass with waste paper powder. The waste paper powder is preferably contained in an amount of 80 to 120 parts by weight based on 100 parts by weight of the polymer resin. When the content of the waste paper powder is less than 80 parts by weight, there is a disadvantage that the decomposability of the plastic product produced due to the content is insufficient compared to the polymer resin, and when it exceeds 120 parts by weight, the content is excessive compared to the polymer resin, rather mechanical The disadvantage is that the physical properties can be weakened.

Glue is a material that solidifies the liquid by orphaning animal skin, intestines, and bones, and acts as a binder that combines polymer resin and waste paper powder. Conventionally, as a binder, synthetic resins such as linear low density polyethylene (LLDPE), low density polyethylene (LDPE), and high density polyethylene (HDPE) are used. They blend the mixed composition well, but since they are synthetic resins, degradability of the final product plastic product Lowered. On the other hand, glue can be easily entangled between polymer resin and waste paper powder, while enhancing the degradability of the final product plastic product, thereby enhancing the environmentally friendly characteristics. Glue is preferably included in 40 to 60 parts by weight with respect to 100 parts by weight of the polymer resin. If the content of the glue is less than 40 parts by weight, the polymer resin and waste paper powder may not be properly entangled, resulting in a poor shape of the plastic product, and when the content is greater than 60 parts by weight, the content of the polymer resin is relatively As a result, the mechanical properties of the final plastic product are reduced.

Linoleic acid is an unsaturated fatty acid for accelerating the decomposition of finally produced plastic products to promote pyrolysis and photolysis. Linoleic acid can be used in combination with myristoleic acid, myristoleic acid is an unsaturated fatty acid having a double bond, which has the advantage of further promoting the polymer degradation function by automatic oxidation. In addition, other unsaturated fatty acids having a function similar to linoleic acid or myristoleic acid can also be used. Linoleic acid is preferably contained in 0.5 to 2 parts by weight based on 100 parts by weight of the polymer resin. If the content of linoleic acid is less than 0.5 parts by weight, there is a disadvantage that the degree of improvement of the degradability of the plastic product may be insignificant, and if it exceeds 2 parts by weight, the manufacturing cost may be increased beyond the required amount. In addition, when linoleic acid and myristicoleic acid are used together, the two components are preferably used in a weight ratio of 1: 1 in terms of improving the degradability of plastic products.

Maleic acid (maleic acid) is an organic acid component that serves as an intermediate and an oxidative decomposition agent for bonding the polymer resin and waste paper powder. Maleic acid is preferably included 1 to 3 parts by weight based on 100 parts by weight of the polymer resin. When the content of maleic acid is less than 1 part by weight, the degree of improvement of degradability of the plastic product may be insignificant, and there is a disadvantage that the molding of the product may not be performed smoothly. The disadvantage is that the cost can be increased.

The silane coupling agent contributes to improving the bonding force between the polymer resin and the waste paper powder, and complements the function of the glue. The silane coupling agent may use a vinyl-based silane coupling agent, preferably vinyl trichlorosilane, vinyl trimethoxysilane, vinyl triethoxy silane, and the like, but is not limited thereto. It is preferable that a silane coupling agent is contained in 0.5-5 weight part with respect to 100 weight part of polymer resins. If the content of the silane coupling agent is less than 0.5 parts by weight, the effect expressed by the silane coupling agent may not be obtained. If the content of the silane coupling agent is more than 5 parts by weight, the polymer resin and the closed bridge powder may be mixed unevenly.

The organic peroxide is used to improve the functionality of the silane coupling agent, and a small amount is added to function as a crosslinking agent. Organic peroxides include 2,5-dimethylhexane, 2,5-dihydro peroxide, 2,5-dimethyl-2,5-di (t-butylperoxy) hexane, 3-di-t-butyl peroxide , n-butyl-4,4-bis (t-butylperoxy) butane, 2,2-bis (t-butylperoxy) butane, 1,1-bis (t-butylperoxy) cyclohexane, 1, 1-bis (t-butylperoxy) -3,3,5-trimethylcyclohexane, t-butylperoxybenzoethone, benzoyl peroxide, t-butyl (2-ethylhexyl) monoperoxycarbonate, t -Butyl isopropyl monoperoxycarbonate, t-amyl (2-ethylhexyl) monoperoxycarbonate, 1,1-di (t-butylperoxy) cyclohexane, 1,1-di (t-butylperoxy At least one selected from) -3,3,5-trimethylcyclohexane and 1,1-di (t-amylperoxy) cyclohexane can be used. The organic peroxide is preferably contained in 0.01 to 0.03 parts by weight based on 100 parts by weight of the polymer resin.

Pellets for producing a plastic product according to an embodiment of the present invention can be prepared by further adding activated carbon powder in order to reduce the off-odor problem. Activated carbon has many pores, so it can adsorb molecules that cause off-flavor problems and also have antibacterial effects. Activated carbon powder is preferably contained 1 to 5 parts by weight based on 100 parts by weight of the polymer resin. If the content of the activated carbon powder is less than 1 part by weight, there is a disadvantage that can not effectively reduce the off-odor problem, if it exceeds 5 parts by weight, it is not only excessively uneconomical but rather weaken the mechanical properties of the plastic product produced There are disadvantages.

Pellets for producing a plastic product according to an embodiment of the present invention may be prepared by further adding sucrose (C ₁₂ H ₂₂ O ₁₁ ) to smoothen the polymer resin or waste paper powder to enhance the binding force. That is, sucrose smoothes the pores formed between the polymer resin and the waste paper powder so that graft bonding is easily performed between the polymer resin and the waste paper powder. In addition, sucrose may also become viscous in the process of mixing with the polymer resin and may trap molecules that cause off-flavor problems, thereby contributing to the solution of off-flavor problems. Sucrose is preferably used in a powder containing 95 wt% or more of 1 ~ 120 ㎛ particle size filtered by 120 mesh (mesh), and preferably contained 1 to 5 parts by weight based on 100 parts by weight of the polymer resin. When the content of sucrose is less than 1 part by weight, the effect expressed by sucrose is insignificant, and when it exceeds 5 parts by weight, the mechanical properties of the plastic product to be produced may be weakened.

Pellets for producing a plastic product according to an embodiment of the present invention may be prepared by further adding calcium oxide to improve the antimicrobial properties. Calcium oxide has a strong bactericidal or virucidal effect on bacteria, fungi and viruses, and can be produced by firing scallop shells. Specifically, the pulverized product obtained by washing, drying and crushing the scallop shell was calcined at 20 to 300 ° C. under a non-oxidizing atmosphere, and then mesophilic at 500 to 700 ° C. under an air atmosphere, and then 1100 to 1300 ° C. under an air atmosphere. It can be fired at high temperature and finely pulverized to produce an average particle diameter of 20 mu m or less. Calcium oxide is preferably contained in 1 to 5 parts by weight based on 100 parts by weight of the polymer resin. When the content of calcium oxide is less than 1 part by weight, the antibacterial effect expressed by the calcium oxide is insignificant, and when it exceeds 5 parts by weight, it is uneconomical.

Next, the manufacturing method of the pellets for plastics manufacture is demonstrated. In the description, overlapping parts will be omitted.

Pellet production method for producing a plastic product according to an embodiment of the present invention comprises a first step of producing waste paper powder by grinding waste paper into fine powder; A second step of preparing a composition by mixing the produced waste paper powder with a polymer resin, glue, linoleic acid, maleic acid, a silane coupling agent and an organic peroxide; And a third step of extruding the composition to produce pellets. The present invention is a method for producing a pellet that can be used to produce a plastic product, it is possible to produce a plastic product having the same or similar mechanical properties as the plastic product using a conventional synthetic resin pellets using the prepared pellets. In addition, unlike plastic products manufactured using biomass, odor problems can be minimized, and the use of glue as a binder has an effect of improving degradability.

The first step is to grind the waste paper into fine powder, and the waste paper is preferably formed into fine powder having a size of 100 to 400 mesh. If it is less than 100 mesh, the average particle diameter of the fine powder is too large, so that the pellets may have poor flowability and productivity, and if it exceeds 400 mesh, the grinding process may take too long, resulting in lower overall productivity and manufacturing cost. This can go down, but rather adversely in terms of dispersibility.

The second step is to prepare a composition for preparing the pellets, the waste paper powder prepared in the first step and the polymer resin, glue, linoleic acid, maleic acid, silane coupling agent and organic peroxide. At this time, activated carbon powder, sucrose and / or calcium oxide may be further added to reduce off-flavor problems, improve physical properties and antimicrobial properties of the mixture, and the like will be omitted herein because such specific components and contents are described above.

The third step is to produce a pellet by extruding the mixed composition prepared in the second step, using a twin screw extruder (twin extruder) while strengthening the binding force between the polymer resin and the waste paper powder while conveying, blowing and drying Pellets can be made by cutting or die-face hot-cutting.

Specifically, the third step is preferably performed under the conditions of the reaction temperature 100 ~ 300 ℃, screw rotational speed 300 ~ 800rpm using an extruder. If the reaction temperature is less than 100 ℃ may not proceed the reaction because the added raw materials are not melted, if the temperature exceeds 300 ℃ carbonization occurs or the temperature is too high may melt the resin like water may worsen the moldability of the pellets. In addition, if the screw rotational speed is less than 300rpm, productivity may be deteriorated, sufficient mixing and reaction may be difficult, and if the screw rotational speed exceeds 800rpm, the internal pressure of the screw rises and the carbonization may increase due to the temperature increase due to the pressure. have.

Hereinafter, the configuration of the present invention and its effects through specific examples and comparative examples will be described in more detail. However, this embodiment is intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.

Example 1

100 parts by weight of polyethylene resin (Honam UL814), 100 parts by weight of waste paper powder crushed newspaper waste paper into 300 mesh fine powder, 50 parts by weight of glue, 1 part by weight of linoleic acid, 2 parts by weight of maleic acid, 2 parts by weight of silane coupling agent, 2 After preparing the composition by mixing 0.02 parts by weight of, 5-dimethyl-2,5-di (t-butylperoxy) hexane, pellets were prepared using a twin screw extruder (reaction temperature of 200 ° C., screw rotational speed of 400 rpm). Prepared.

Example 2

A pellet was prepared in the same manner as in Example 1, except that 3 parts by weight of activated carbon powder was further added.

Example 3

The pellets were prepared in the same manner as in Example 2, except that 3 parts by weight of sucrose having a particle size of 100 μm and 3 parts by weight of calcium oxide produced by calcining and pulverizing the scallops were added.

Comparative Example 1

Pellets were prepared in the same manner as in Example 1, except that no waste paper powder and glue were contained.

Comparative Example 2

Pellets were prepared in the same manner as in Example 1, except that biomass powder obtained by grinding corncobs instead of waste paper powder and linear low density polyethylene (LLDPE) instead of glue was used.

Experimental Example

After injection molding a test sample of a plastic product using the pellets of Examples and Comparative Examples, the following experiments were conducted.

Specific gravity measurement

Specific gravity was measured according to the ASTM D test method, the results are shown in Table 1 below.

TABLE 1

As can be seen in Table 1, Examples 1 to 3 were lighter in specific gravity than Comparative Example 1, which is a conventional synthetic resin product, and accordingly, the product unit cost was about 10% or more when a plastic product was produced by molding the same weight of raw materials. It can be seen that it can have a reducing effect. In particular, in Examples 2 and 3 to which activated carbon powder was added, it was confirmed that the specific gravity is lower.

Tensile Strength Measurement

Tensile strength was measured using a universal testing machine (ASTM D 3826), and the results are shown in Table 2 below.

TABLE 2

As can be seen in Table 2, Examples 1 and 2 prepared using waste paper powder also showed a similar strength to that of the synthetic resin product. However, in the case of Example 3 to which more sucrose was added, it could be predicted that the tensile strength was increased through a more rigid graft bond.

Degradability Test

After inoculation of the mold to each sample by the ASTM G 21 test method and incubated for 60 days at 28 to 30 ° C. and a relative humidity of 85%, the sample was decayed according to the following Equation 1, and the ratio of the weight loss was measured. The results are shown in Table 3 below.

[Equation 1]

Weight loss rate (%) = weight after sampling / weight of original sample x 100

TABLE 3

As can be seen from Table 3, Comparative Example 1 hardly decomposed. On the other hand, in Examples 1 to 3 and Comparative Example 2, it was found that the degradability is excellent. It can be expected that Examples 1 to 3 exhibited improved degradability compared to Comparative Example 2 because glue was used as the binder.

Antimicrobial test

The antimicrobial activity test (JIS Z 2801) was performed about the pellet compositions of Examples 1-3 and Comparative Example 2. Test strains were used Staphylococcus aureus ATCC 6538 (E. coli), Escherichia coli ATCC 25922 (E. coli), and the antimicrobial activity (antimicrobial activity) was evaluated in Table 4 below.

TABLE 4

The antimicrobial activity value is the value of the antimicrobial evaluation by comparing the number of strains cultured for a certain time. If the value is 1 or more, 90% or more strains, if 2 or more, 99% or more strains, 3 or more, 99.9% or more strains If 4 or more, 99.99% or more strains, 5 or more, 99.999% or more strains are considered to have an antimicrobial effect. In the case of Example 2, the antimicrobial effect by the activated carbon appeared, and in Example 3, it was predicted that the antimicrobial effect by the activated carbon and calcium oxide.

Odor test

Off-flavor test was conducted for each sample and the results are shown in Table 5 below.

TABLE 5

As shown in Table 5, in the case of Comparative Example 2, off-flavor problems occurred (O), in the case of Example 1 occurred, but was insignificant (△). In the case of Comparative Example 2, it was found that the carbonization phenomenon caused by lignin occurred during the manufacturing process using the cornstalk. However, in the case of the Example, it was determined that lignin was removed using waste paper powder so that off-flavor problems hardly occurred. In particular, in Examples 2 and 3, odor problems were hardly generated due to activated carbon, sucrose and the like.

In the present specification, only a few examples of various embodiments performed by the present inventors are described, but the technical idea of the present invention is not limited thereto, but may be variously modified and implemented by those skilled in the art.
