Abstract
The present invention relates to a regenerating filler compound of a discarded mixed resin film. The filler compound is a mineral powder mixture comprising 45-55 wt% of magnesia (MgO), 30-40 wt% of calcium carbonate (CaCO 3 ), and 10-20 wt% of zeolite and; Oxide transition metal element additive; A filler containing a vanadium catalyst for compatibilizing is grafted and extruded into a thermoplastic synthetic resin to form pellets.
Description
The present invention relates to a filler compound for recycling a waste synthetic resin film, and more particularly, to a filler compound which can improve properties such as miscibility, compatibility and impact resistance by using an inorganic material as a main material, .
Generally, films made of thermoplastic synthetic resin are produced in various kinds by using PE (polyethylene), PP (polypropylene), PVC (polyvinylchloride), PET (polyethylene terephthalate), PEF (polyethylene film) and Nylon. Particularly, as in the case of PE, it may be finely divided according to a specific purpose and use such as high density (HD), low density (LD) and low density (LLD). In the case of food packaging, another material such as nylon Film is also provided.
In terms of applications, thermoplastic synthetic resin films are widely used for a variety of purposes in fields such as agriculture, industrial use, commercial use, and household use. The problem lies in the disposal of used waste plastic film.
For example, if the waste synthetic resin film can be selectively sorted according to the type and physical properties, a considerable portion thereof may be easily recycled. However, in the process of collecting, collecting, and collecting, it is a reality. Therefore, these synthetic resin films are discarded and incinerated or buried when they are used. When they are incinerated, they release toxic substances such as dioxin and cause serious air pollution. When they are buried, they do not decompose in the soil and destroy the ecosystem. It is becoming a main cause of environmental pollution.
In recent years, methods for recycling waste synthetic resins by sorting, separating, washing, and recycling the waste synthetic resin have been developed for the purpose of recycling resources. However, these techniques are used for sorting, separating, It is difficult to apply this method to a small-sized company that does not deviate from the small-sized company because the cost of labor and the cost of manufacturing are lowered.
Therefore, development of a new technology for recycling waste synthetic resin is required. Particularly, a filler capable of regenerating waste synthetic resin in an environmentally friendly manner and its use have been demanded.
A proposed synthetic resin composition for regenerating waste synthetic resin disclosed in Patent Publication No. 2003-77517. According to the disclosed composition, the above-mentioned additive agent comprises 0.01 to 1.0 part by weight of a transition metal element and 0.1 to 10 parts by weight of a stabilizer in 100 parts by weight of dolomite, 10 to 20 parts by weight of fly ash, 5 to 10 parts by weight of sericite and 5 to 10 parts by weight of zeolite, 0.5 part by weight. The mixture is mixed with 20 to 30 parts by weight of 100 parts by weight of pulverized synthetic resin pulverized at 5 to 10 mm 2 without being subjected to a screening or separation operation, heated at a high temperature and extruded to obtain a recycled synthetic resin.
As described above, dolomite is used as the main material as the inorganic compound mixture. This is because dolomite contains magnesia, which is well known as a basic refractory material, and can control the melting temperature of various waste synthetic resins having different melting point temperatures. However, since dolomite generally contains calcite and soluble components above magnesia, dolomite is required in a considerably large amount in order to sufficiently exhibit the above characteristics. In the above-mentioned composition, 100 parts by weight of dolomite is mainly used.
That is, even if the above-mentioned composition is considered to be useful for regenerating the waste synthetic resin, it can be said that the material, particularly dolomite, is used in a wasteful manner. In other words, it is quite disadvantageous from the economical point of view.
A proposed synthetic resin filler disclosed in Japanese Patent Laid-Open Publication No. 2011-25368 is proposed. According to the disclosed disclosure, the filler comprises a mineral-based mixture of crushed and ground magnesia, magnesia ore, basalt, flyash, zeolite and the like; An oxide transition metal element and an additive including a stabilizer. In the case of this filler, by using magnesia ore instead of dolomite, it is possible to function more than a conventional filler in a small amount. In this case, it is premised that a basalt is combined with a sericite instead of a sericite as an inorganic material for melt-bonding with a synthetic resin.
As in this patent, it is recognized that the use of magnesia ore is advantageous over using dolomite. On the other hand, however, the problem of melt-bonding is inevitably serious, and here, the disadvantage in terms of the combination of a considerable amount of basalt as an inorganic material for this is likewise disadvantageous. In a preferred embodiment, for example, the magnesia and basalt in the mixture are each 30-40% by weight and are described in the same amounts.
Conversely, since the magnesia ore is not used as much as the amount of basalt required in the filler, the magnesia content is not actually increased in the filler, but the magnesia content is not substantially increased, There is also a problem. These problems are offset by the disadvantage of offsetting the advantageous benefits of the patent, and ultimately the patent shows no benefit.
To solve this problem is a compatibilizing filler for regenerating waste synthetic resin disclosed in Japanese Patent No. 1463400. It has been disclosed that the fillers herein are intended to exclude the use of separate basalt using a magnesium-dolomite with MgO and CaO composition ratios of 60-70: 30-40. However, the specific content of the stones is not uncommon, and it is almost impossible to apply them.
On the other hand, all the above patents disclose a filler based on an inorganic raw material mineral containing a magnesia component. It is true that this component plays a role in controlling the melting temperature of various waste-mixed synthetic resin films having different melting points. It is also disclosed that sericite or basalt can be used as a binder or not used separately.
However, the discarded and mixed synthetic resin films have different physical properties, and therefore, the processing conditions such as the melting temperature and the RPM may vary greatly. As a result, the interfacial temperature response changes during the recycling process, and the surface morphology itself is changed differently, resulting in incomplete commercialization. As a result, the problem that the compatibility and impact resistance required for molding extrusion or injection can not be obtained have.

Patent No. 1463400
The present invention has been proposed to solve the problems of the above-mentioned prior arts. An object of the present invention is to provide a filler capable of greatly improving miscibility and impact resistance when recycled waste synthetic resin films are added by using a specific catalyst based on an inorganic material containing magnesia as a main material . In other words, the present invention aims at solving the problem of miscibility, compatibilization and impact resistance of the conventional filler in terms of the catalyst.
The filler compound of the present invention comprises:
Magnesia (苦土, MgO) mineral-based powder mixture comprising 45-55 wt.%, Calcium carbonate (輕炭, CaCO 3) 30-40 % by weight, zeolite (沸石, zeolite) 10-20% by weight and; Oxide transition metal element additive; A filler comprising a vanadium catalyst for compatibilization,
Grafting and extruding the thermoplastic synthetic resin,
Formed of pellets,
.
Preferably, the transition metal element includes at least one selected from the group consisting of aluminum oxide, titanium oxide, iron oxide, cobalt oxide, and silver. The transition metal element additive is added in an amount of 10-20 parts by weight based on 100 parts by weight of the mixture.
Preferably, the vanadium catalyst is a vanadium salt (VOCl 3 ), which is composed of 30 wt% of vanadium, 60 wt% of chlorine (powder), and 10 wt% of other metal elements. The vanadium catalyst is added in an amount of 5-10 parts by weight based on 100 parts by weight of the mixture.
The filler of the present invention is based on an inorganic material containing magnesia as a main material and a specific catalyst, that is, a vanadium catalyst is added thereto, and is applied as a filler in regenerating a waste synthetic resin film.
The materials are as environmentally friendly as possible;
As a result, compatibility and impact resistance can be greatly improved;
It is effective.
The features and effects of the invention "regenerating filler compound " of the discarded mixed resin film (hereinafter" filler compound ") described or not described above will become more apparent through the description of the embodiments described in detail below .
The filler compound according to the present invention is characterized by being formed into pellets by grafting and extruding a compatibilizing filler into a thermoplastic synthetic resin.
The filler according to the present invention is characterized in that an inorganic oxide powder mixture obtained by crushing and grinding magnesia (hard soil, MgO), calcium carbonate (CaCO 3 ) and zeolite is mixed with an oxide transition metal element additive, And a vanadium catalyst.
The mixture here is magnesia (苦土, MgO) 45-55% by weight of calcium carbonate (輕炭, CaCO 3) 30-40% by weight of zeolite mineral-based powder containing (沸石, zeolite) 10-20% by weight . Magnesia in the mixture can be applied as a basic refractory material by appropriately adjusting the melting temperature of various waste synthetic resins.
In addition, the mixture contains a certain amount of calcium carbonate and zeolite to smoothly melt the waste synthetic resin and to form a binder. The calcium carbonate and the zeolite are mixed together with a small amount of the calcareous component of the magnesia, Thereby facilitating formation. In particular, calcium carbonate plays a role as a compatible filler having excellent adsorption and bonding properties upon melting.
Generally, various kinds of waste synthetic resins are mixed and crushed, and heated and extruded by heating at a temperature higher than the recrystallization temperature to carbonize and decompose due to their different melting points and densities, making extrusion impossible. By standardizing the difference in melting point, it is possible to remove moisture and the like and to induce formation of a specific bond.
The oxide transition metal element of the present invention neutralizes, deodorizes, and removes soot containing toxic gases such as dioxin and chlorine gas generated during the heat extrusion of a foreign substance to further smoothly induce the combined body. The above-mentioned zeolite can also be helpful for heavy metal neutralization. The oxide transition metal elements that can be used here include aluminum oxide (Al 2 O 3 ), titanium oxide (TiO 2 ), iron oxide (Fe 2 O 3 ), cobalt oxide (CO 2 CO 3 ), silver (Ag) , And one or more transition metal elements selected therefrom are added to the mixture.
The oxide transition metal element is added in an amount of 10-20 parts by weight based on 100 parts by weight of the mixture. More specifically, the transition metal element is most preferably composed of 40 wt% of aluminum oxide, 40 wt% of titanium oxide, and 20 wt% of other elements.
The vanadium catalyst of the present invention plays an important role as a means for commercializing various waste synthetic resins, in particular, as a means for improving the compatibility and miscibility between synthetic resin interfaces and maintaining morphology uniformly.
The vanadium catalyst is vanadate (VOCl 3 ), and preferably the vanadium catalyst is added in an amount of 5-10 parts by weight based on 100 parts by weight of the mixture. More specifically, the vanadium catalyst is composed of 30 wt% of vanadium, 60 wt% of chlorine (powder), and 10 wt% of at least one element selected from silicon, aluminum, iron, titanium, chromium and nickel.
In the present invention, the above-mentioned filler is grafted and extruded into thermoplastic synthetic resin to form pellets, and the obtained pellets can be used for regeneration of the waste synthetic resin. Preferably, the thermoplastic synthetic resin is a polyethylene (PE) resin, which accounts for 60% of the total synthetic resin production. By subdivision, high-density PE is more suitable.
More specifically, the pellet is composed of 60 to 80% by weight of the filler and 20 to 40% by weight of a polyethylene resin as thermoplastic synthetic resin.
Example 1: Filler compound
First, 50% by weight of magnesia, 35% by weight of calcium carbonate and 15% by weight of zeolite were crushed and pulverized into 320 mesh to prepare an inorganic mixture. Then, 100 parts by weight of the mixture was mixed with an oxide containing aluminum oxide, titanium oxide, 15 parts by weight of a transition metal element and 5 parts by weight of a vanadium catalyst containing vanadium and chlorine (powder) were mixed to obtain an inorganic filler.
Next, 70% by weight of a filler and 30% by weight of a high-density polyethylene (HDPE) resin are mixed and poured into an extruder having a discharge port to pelletize the filler. At this time, the melting temperature is 190-200 占 폚 (concretely, the hopper inlet cylinder temperature is 200 占 폚, the middle discharge cylinder temperature is 220 占 폚, the die temperature is 190 占 폚), and RPM / Then, extrusion and cutting are performed to obtain a filler compound in the form of pellets according to the present invention.
In other embodiments, the present invention is applied to the range or kind defined in the present invention under the same conditions, but as a result, there is no significant difference in comparison with the present embodiment, so the description thereof will be omitted.
≪ Example 2 >: Recycling of waste synthetic resin
A regenerated synthetic resin was prepared using the filler compound prepared in Example 1 above. Waste Mixed synthetic resins were obtained from field dumplings, of which PE (HD) was the most prevalent in 67% of the randomly grouped samples. Relatively PP, PVC, PET, etc. make up at most 10% because of the high production amount of PE, and it is also a basis for using PE as a draft material in the present invention.
The waste synthetic resin was ground to a size of 10 mu m without selection. 85% by weight of the pulverized waste synthetic resin and 15% by weight of the filler compound of the present invention were mixed and then heat-extruded to prepare a recycled synthetic resin. At this time, the extrusion processing conditions were a hopper inlet cylinder temperature of 180 占 폚, an intermediate discharge cylinder temperature of 210 占 폚, a die temperature of 190 占 폚, and RPM / min of 32 times.
As a result, the recycled recycled synthetic resin was obtained by removing the soot and odor containing toxic gas such as dioxin by using a filler obtained by adding a transition metal element, which is an oxide, and a vanadium catalyst to an inorganic mixture, It was confirmed that foreign substances such as chromaticity were neutralized and the thermal expansion coefficient was evenly minimized.
Tensile strength, bending strength and thermal expansion coefficient of the thus-produced recycled synthetic resin were measured. The tensile strength was measured in accordance with KSM 3006-193 1 type (test pin tensile speed 50 mm / min), bending strength KSM 3008-83, and thermal expansion coefficient according to KSM 3015-97. Respectively.
Control experiments (1) and (2) in Table 1 are experiments on recycled synthetic resins obtained using conventional fillers based on dolomite and magnesia, respectively. Here, when the filler compound of the present invention is used, the characteristics of the recycled synthetic resin obtained therefrom are superior to those of the conventional case. In addition, considering that the effect of the filler compound of the present invention results from the commercialized coupling properties obtained only by the vanadium catalyst and pelletization, the total charge compound of the present invention is considered to be sufficiently competitive.
