Description

Yellow earth resin composition emitting far-infrared rays and polymer articles having improved mechanical properties and esthetic surface characteristics manufactured using the same

The present invention relates to an ocher resin composition and an ocher polymer article prepared by using the same, and more particularly, to an ocher resin composition and a far infrared ray emitting ocher polymer article having improved mechanical properties and beautiful appearance characteristics prepared using the same.

Background Art Conventionally, resin compositions obtained by compounding ocher, which has functional properties such as far-infrared radiation properties, antibacterial properties, and deodorizing properties, with synthetic resins have been developed and used in the manufacture of food containers, electronics housings, flooring materials and the like.

For example, Korean Patent Publication No. 10-2000-0066632 discloses a resin of any one of polypropylene, polyethylene, and polyethylene terephthalate, 5 to 20% by weight of fine clay powder of 1 to 3 µm, 2 to 3% by weight of coupling agent, It discloses a loess-containing synthetic resin composition and a method for producing the same, characterized in that 0.5% by weight of butyl stearate, 10% by weight of fine resin powder, and the remainder are made of synthetic resin in the same chip state as the synthetic resin.

Korean Patent Publication No. 10-2003-0096514 discloses 1 to 30% by weight of one or more powders of loess, mud, illite, charcoal, jade, quartz, 1-10 μm in size, 2-3% by weight of coupling agent, butylstearate 0.5 Disclosed is a method for producing a composite resin chip from a weight% and a composition consisting of a synthetic resin powder.

Korean Patent Publication No. 10-1999-0044822 discloses a resin composition consisting of 70% by weight of ocher, 10% by weight of low density polyethylene, 5% by weight of plasticizer such as DOP, 5% by weight of dispersant, and 10% by weight of shedding agent such as paraffin wax. .

However, in the case of the above composite resins, a large amount of a liquid coupling agent or a low molecular weight dispersant such as γ-methacryloxy-propyltrimethoxysilane must be used in order to assist mixing of the resin with fillers such as loess. There are disadvantages.

(1) When the coupling agent is used in compounding, a separate mixing process of the liquid coupling agent and the loess is added, and the coupling agent is diluted in a large amount of a lower alcohol solvent such as methanol to facilitate the dispersion of the liquid coupling agent. Should be used. This complicates the manufacturing process and increases the manufacturing cost.

(2) Since the coupling agent and the low molecular weight dispersant are transferred to the surface of the molded product to contaminate the appearance of the product, the surface state is not good and it is difficult to obtain a beautiful appearance product.

(3) Coupling of synthetic resin and loess is not enough, so tensile strength is improved but impact strength is poor.

Accordingly, the technical problem to be achieved by the present invention is to provide an economical synthetic resin composition which can easily obtain molded products having excellent mechanical properties such as tensile strength, flexural strength, flexural modulus, impact strength, and good appearance characteristics. .

One embodiment of the present invention to achieve the above technical problem,

60 to 99% by weight of base resin;

0.1 to 20% by weight loess powder having a 325 mesh pass through ratio of 98 to 100% by weight; And

It is different from the loess powder, and has an average particle diameter of 1 ~ 2㎛ far infrared emitter powder 0.1 to 20% by weight; provides an ocher resin composition comprising a.

The ocher resin composition may optionally have 0.1 to 10 weight of a polymer compatibilizer having a weight average molecular weight of 30,000 to 50,000 g / mol to improve the interfacial adhesion between the ocher powder and the far-infrared radiator powder and the base resin and the flowability of the entire resin composition. It may further include%.

The ocher resin composition of the present invention is an ocher resin composition of the present invention in which an interface between an inorganic filler and a base resin is reinforced by using a complex system of ocher powder / far infrared emitter powder and optionally a polymer compatibilizer. Compared with the far-infrared radiation resin composition supplemented by a silane coupling agent, mechanical properties and appearance characteristics such as impact resistance and tensile strength are excellent. Therefore, the ocher resin composition of the present invention can be usefully used for manufacturing by injecting, extruding, or blow molding a household article including a far infrared ray-releasing polymer article, especially an ocher food container.

Hereinafter, the ocher resin composition according to the present invention will be described in detail.

Ocher resin composition according to an embodiment of the present invention is 60 to 99% by weight of the base resin; 0.1 to 20% by weight loess powder having a 325 mesh pass through ratio of 98 to 100% by weight; And from 0.1 to 20% by weight of far-infrared emitter powder different from the ocher powder and having an average particle diameter of 1 to 2 µm.

The base resin is not particularly limited, such as polyolefin resin, polyamide resin, polyester resin, polycarbonate resin, melamine resin, phenol resin, etc., but economical aspects, chemical resistance, ocher powder and far-infrared emitter powder and polymer commercialization will be described below. In terms of compatibility with the product, it is preferable that the polyolefin resin having a melt index of 1 to 100 g / 10 minutes measured at a temperature of 230 ° C. and a load of 2.16 kg according to the specification described in ASTM D1238, and has a melt index of 5 to 50 g. More preferably, it is a polyolefin resin which is 10 minutes. If the melt index is less than 1g / 10min, injection molding may be degraded. If the melt index is more than 100g / 10min, the impact characteristic may be significantly reduced.

The polyolefin resin is particularly preferably a polypropylene, polyethylene or ethylene-propylene copolymer in view of availability, mechanical properties and economics. The term "polyethylene" herein means not only a homopolymer of ethylene but also a copolymer in which at least 85% of the repeating units are ethylene units. By "polypropylene" is meant to include not only homopolymers of propylene but also copolymers in which at least 85% of the repeating units are propylene units. "Ethylene-propylene copolymer" means a copolymer of ethylene-propylene wherein more than 15% and less than 85% of the repeating units are propylene units or ethylene units. Herein, the form of the copolymer is not particularly limited and includes random copolymers, block copolymers, graft copolymers or mixtures thereof.

If the content of the base resin is less than 60% by weight, the content of the loess powder and the far infrared emitter powder is increased so that the far-infrared emissivity increases, but the mechanical properties of the molded article are insufficient and the appearance defect is also not preferable. When the content of the base resin exceeds 99% by weight, the content of the ocher powder and the far infrared emitter powder is too small, resulting in insufficient far infrared emissivity.

The ocher resin composition according to an embodiment of the present invention includes an ocher powder and other far infrared emitter powders as far infrared emitters.

The ocher powder has a 325 mesh through fraction of 98 to 100% by weight, preferably 325 mesh through fraction of 99.5 to 100% by weight. If the 325 mesh passing fraction is less than 98% by weight, there is a problem in that the appearance of the molded article is poor.

The far-infrared emitter powder is mud, clay, kaolin, white clay, elvan, illite, biotite, tourmaline, jade, zeolite, cordierite, graphite or a mixture thereof, characterized in that the average particle diameter is 1 ~ 2㎛. Far-infrared radiator powder shows far-infrared emissivity equivalent to that of ocher powder, but its powder size is much smaller. Therefore, it acts as a lubricant when melting the base resin and increases the fluidity of the resin composition. Physical properties can be improved.

The content of ocher powder and far-infrared emitter powder is preferably 0.1 to 20% by weight, respectively. If the content of the ocher powder is less than 0.1% by weight, there is a problem of lowering the far-infrared emissivity, and if it exceeds 20% by weight, the impact strength is significantly lowered and the appearance is poor. If the content of the far-infrared radiator powder is less than 0.1% by weight, there is a problem in that the performance expression as a lubricant and a nucleating agent is not sufficient, and if it exceeds 20% by weight, the impact strength is lowered.

If the average particle diameter of the far-infrared radiator powder is less than 1 µm, it is difficult to inject the radiator in the extrusion process, and if it exceeds 2 µm, there is a problem that performance expression as a lubricant and a nucleating agent is not sufficient.

As described above, the ocher resin composition of the present invention is a composite of a combination of ocher powder having a relatively large particle diameter, which exhibits far-infrared radiation characteristics, deodorization characteristics, antibacterial characteristics, and the like, and fine particle-sized far-infrared radiator powder which affects dispersion and improvement of physical properties of the composite resin. It is used as an inorganic filler. As a result, the far-infrared radiator powder of fine particle size plays a role of lubricant and nucleating agent in addition to the function of far-infrared radiation. Mechanical properties such as strength injection processability, extrusion processability, dimensional stability, surface hardness and scratch resistance can be improved. Here, the term "nucleating agent" refers to an additive which acts as a crystal nucleus in the cooling process after thermoforming and increases the crystallinity of the crystalline base resin to increase the mechanical properties of the polymer article.

The ocher resin composition according to another embodiment of the present invention optionally has a weight average molecular weight of 30,000 to 50,000 g / mol to improve the interfacial adhesion between the ocher powder and the far infrared emitter powder and the base resin and the flowability of the entire resin composition. The polymer compatibilizer may further include 0.1 to 10% by weight.

When the weight average molecular weight of the polymer compatibilizer is less than 30,000 g / mol, there is a problem in that the compatibilizer migrates to the surface and generates stains at high temperature molding such as injection molding and extrusion molding. When the weight average molecular weight of the compatibilizer exceeds 50,000 g / mol, there is a problem that the flowability and moldability of the resin composition are lowered.

If the content of the polymer compatibilizer is less than 0.1% by weight, the effect of adding the polymer compatibilizer may not be substantially obtained. If the content of the polymer compatibilizer is more than 10% by weight, the bonding force between the loess and the far-infrared radiator and the base resin may be excessively increased, thereby reducing the thermoformability of the resin composition. There is a problem.

Examples of the polymer compatibilizing agent include modified polypropylene, modified polyethylene, and modified polyunsaturated polypropylene, polyethylene or ethylene-propylene copolymer in which a backbone chain is grafted in an amount of 0.3 to 10% by weight based on the weight of the backbone chain. It is preferable that it is an ethylene-propylene copolymer, since the optimum compatibilization effect with a base resin can be acquired.

If the graft amount of the unsaturated monomer is less than 0.3% by weight based on the weight of the backbone chain, commercialization performance is difficult to expect, and when it exceeds 10% by weight, the commercialization performance reaches a saturation state. Do not increase over.

The unsaturated monomer grafted to the backbone chain is not particularly limited, but specific examples thereof include acrylic acid, methacrylic acid, maleic acid, fumaric acid, maleic anhydride, methyl maleic acid, methyl maleic anhydride, acrylamide, vinyl benzoic acid, vinylaniline, vinylpyridine, and styrene sulfide. Sodium salt of phonic acid or mixtures thereof;

In the polymer compatibilizer, the backbone chain of the polypropylene, polyethylene or ethylene-propylene copolymer is a part having affinity for the polyolefin base resin, and the polar unsaturated monomers grafted thereto are ocher powder and far infrared emitter powder. It is a part with affinity. Therefore, by adding the polymer compatibilizer of such a structure, it is possible to improve the interfacial adhesion between the ocher powder and the far infrared emitter powder and the base resin. Therefore, the polymer article manufactured using the resin composition according to another embodiment of the present invention further improves mechanical and appearance properties such as tensile strength, flexural strength, flexural modulus, impact strength, dimensional stability, surface hardness, and scratch resistance. Can be.

The modified polypropylene or modified polyethylene or modified ethylene-based rubber as the polymer compatibilizing agent is a modified polypropylene resin obtained by grafting a physically affinity polar unsaturated monomer to crystalline polypropylene or polyethylene or ethylene-based rubber, It is characterized in that the modified polypropylene or modified polyethylene or modified ethylene-based rubber composition grafted in the ratio of 0.3 to 10% by weight with the acrylic acid, maleic anhydride or methyl maleic anhydride.

The ocher resin composition according to one embodiment and the other embodiments of the present invention described above is an antioxidant, a lubricant, a light stabilizer, a silicone preparation, a release agent, a pigment, an antistatic agent, an antimicrobial agent, an antidropping agent, an antifriction wear agent, or a mixture thereof. Typically, additives added during the manufacture of the composite resin may further include about 0.1 to 5 wt% based on the total weight of the resin composition.

Next, the manufacturing method of the far-infrared radiation resin composition of this invention is demonstrated.

The resin composition of the present invention can be prepared according to any conventional composite resin production method. For example, the base resin, ocher powder and other additives such as far infrared emitter powder, antioxidant, light stabilizer, mold release agent and the like are weighed and dry blended. The mixture is then melt kneaded to obtain a composite resin composition in which each component is uniformly dispersed. Melt kneading is performed in such a manner as to stir while dissolving the base resin using a Banbury mixer, a pressurized kneader, a kneader, a single screw extruder, a twin screw extruder, a brabender, and the like to uniformly disperse each component. Although kneading temperature changes with kinds of base resin, it is the range of about 160 degreeC-280 degreeC, Preferably it is 200 degreeC-250 degreeC. If the kneading temperature is lower than 160 ° C, the kneading takes a long time, the torque applied to the kneading device is increased too much, and the kneading device may be worn. If the kneading temperature is higher than 250 ° C, the energy cost is excessive, and in some cases, There is a risk of thermal decomposition.

If the kneading process is carried out in an extruder, the resin composition is directly pelletized and collected.In the case of a kneading apparatus such as a Banbury mixer or a brabender, the obtained resin composition is extruded from an extruder and cut into pellets of appropriate size at the tip of the extruder. To collect.

The pellets thus obtained can be directly used for producing final polymer articles such as pipes, food containers, sheets, bottles, etc. by molding methods such as injection molding, extrusion molding, blow molding, and blow molding.

Hereinafter, an Example is given and this invention is demonstrated in detail. This is for the purpose of illustration of the present invention, of course, the scope of the present invention is not limited thereto.

As can be seen from Table 1, the resin composition of Examples 1 to 6 is to change the content of both of them in a state in which the total content of the ocher powder and the far infrared emitter powder is fixed to 13% by weight.

According to the change in physical properties, the resin composition of Example 1 including 1 wt% of far infrared emitters in addition to ocher powder showed a tendency to increase all mechanical properties compared to that of Comparative Example 1 which does not include any far infrared emitters. In particular, MFI, flexural modulus and impact strength were increased. It can be seen that the physical properties of the resin composition of Example 2 in which the content of the far-infrared radiator powder is increased to 2% by weight are higher than those of Example 1.

The resin composition of Example 3, in which the content of far infrared emitter powder was further increased to 5% by weight, exhibited almost the same physical properties as those of Example 2. This increases the mechanical properties of the far-infrared emitter powder with fine particle size as a lubricant and nucleating agent, and further increases the mechanical properties than when containing only loess, but this increase effect is saturated when the content of the far-infrared emitter powder is around 2% by weight. .

Therefore, it can be seen that in the composite inorganic filler system of loess powder / far infrared emitter powder, various product requirements can be satisfied without changing physical properties and appearance by changing their content ratio.

In the case of the resin composition of Example 4, which further contains 1% by weight of a modified polypropylene polymer compatibilizer as compared to Example 3, the impact strength was particularly increased, and the surface state of the specimen was excellent. there was. This is presumably because the polymer compatibilizer improves the mechanical properties by improving the interfacial adhesion between the ocher powder and the far infrared emitter powder and the polypropylene copolymer resin. In addition, the beautiful appearance of the specimen is that the polymer compatibilizer has a high molecular weight and a polar compatibilizer for ocher powder and far-infrared emitter powder and a non-polar moiety that is compatible with non-polar resin such as PP copolymer. It is assumed that this is because the surface of the specimen is not stained because it does not migrate to the specimen surface.

In the case of using the polymer compatibilizer, the silane coupling agent or the titanium coupling agent may also be extruded immediately after dry blending with other components without the need for pretreatment and dilution with a lower alcohol solvent. The process for obtaining a master batch also has economic advantages.

In the case of the resin composition of Comparative Example 1 using only ocher powder and does not include a fine far-infrared emitter powder that acts as a lubricant and nucleating agent, the mechanical properties are generally poorer than in the case of the embodiment, and in particular, the tensile strength and the impact strength are low. It can be seen that the polymer article manufactured by the present invention may be destroyed by an external impact.

In the case of Comparative Example 2 when the ocher and polypropylene are coupled using a silane coupling agent, the tensile strength and modulus are slightly improved, but the impact strength due to excessive hardening of the silane coupling agent during the high temperature processing in Examples 1 to 6 It can be seen that it is quite low compared to. In addition, the silane coupling agent migrated to the specimen surface, resulting in poor surface condition. In particular, the production process is complicated by the use of the silane coupling agent, and the production cost is not economical because an alcohol solvent such as methanol must be used separately.

On the other hand, as can be seen from Table 1, the resin compositions of Examples 1 to 6 and Comparative Examples 1 and 2 exhibited almost the same degree of functionality in terms of far-infrared emissivity, antimicrobial activity, deodorization rate, food container safety and the like. From this it can be seen that the resin composition according to the present invention can be usefully used as a master batch for injection molding food containers.

As described above, the ocher resin composition of the present invention, in which the interface between the inorganic filler and the base resin is reinforced by using a complex system of ocher powder / far infrared emitter powder and optionally a polymer compatibilizer, is applied to a conventional ocher resin composition, in particular, a silane coupling agent. Compared with the far-infrared radiation resin composition supplemented by the present invention, mechanical properties such as impact resistance and tensile strength are excellent. Therefore, the ocher resin composition of the present invention can be usefully used for manufacturing by injecting, extruding, or blow molding a household article including a far infrared ray-releasing polymer article, especially an ocher food container.
