Description

Composition for manufacturing polymer composites with excellent thermal stability, polymer composites using the same, and method for manufacturing the same {COMPOSITION FOR PREPARING POLYMER COMPOSITE WITH EXCELLENT THERMAL STABILITY, POLYMER COMPOSITE USING THE SAME AND METHOD FOR PREPARING THEREOF}

The present invention relates to a composition for producing a polymer composite with excellent thermal stability, a polymer composite using the same, and a method for producing the same. More specifically, a composition for producing a polymer composite with improved adhesion and thermal stability, the composite, and a method for producing such a composite. It's about.

Various polymer compounds widely used in daily life have the disadvantage of poor combustion resistance and thermal stability compared to their versatility due to their excellent performance such as mechanical strength. Therefore, research to improve these shortcomings is actively underway. Currently, the four major general-purpose polymer resins commonly used in daily life include polypropylene (PP), polyethylene (PE), polyvinyl alcohol (PVC), and polystyrene (PS). .

Meanwhile, polyurethane is a polymer with the fifth largest consumption market following polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and polystyrene, and is especially the largest among thermosetting resins. It had a large consumer market. Polyurethane is attracting attention as a material for consumer electronics and automobile parts due to its excellent hardness and heat resistance, and has made it possible to manufacture products with various physical properties such as hard and soft foam, film, and fiber. However, polyurethane, a polar polymer, has the disadvantage of poor combustion resistance and poor thermal stability, so its use in applications requiring these properties is limited. For example, Korean Patent Application No. 2014-0053094 relates to a method of modifying a polyolefin-based polymer using waste polyurethane through radiation and a polyolefin-based polymer modified thereby, which involves pulverizing polyurethane into fine powder, and pulverizing the polyurethane into fine powder. Modified polyolefin-based polymers are provided by mixing them with polyolefin-based polymers, but this technology is not a technology that can control thermal stability.

Furthermore, as the possibility of fire due to electrical safety accidents increases, the demand for cross-linked wires that ensure safety such as high heat resistance, flame retardancy, and flame retardancy is rapidly increasing, and with the advent of the electric vehicle era, they are used for charging, power supply, driving, and operating sensors. The demand for high-performance bridging wires that require high safety and control is explosively increasing. Furthermore, as interest in electrical fires, which account for about 50% of frequent large-scale fire accidents, is increasing recently, the use of high-performance cross-linked wires that can withstand higher temperatures for a long time is required, and the wire cross-linking method using existing chemical methods is The process is complex due to the high temperature and/or high pressure, an additional separator is required due to the adhesion of the insulator and the conductor, and the uniformity of the crosslink density is poor, which has the problem of deteriorating physical properties. In addition, the use of organic peroxides as a cross-linking agent has problems such as bad odor or micro-pores generated by by-products after cross-linking, which deteriorates the insulation performance.

In order to solve these problems, a material is required that allows a crosslinking reaction at room temperature without the use of organic peroxides, has a simple process, and has excellent flame retardancy, adhesiveness, and high heat resistance.

In the composition for producing a polymer composite material of the present invention, if the crosslinking agent is included in less than the above range, the improvement in physical properties tends to be insufficient due to insufficient crosslinking, based on the weight of the entire composition, and if it is included in excess of the above range, the crosslinking agent tends to be insufficient to improve physical properties. Crosslinking may actually cause a decrease in physical properties.

In the composition for producing a polymer composite of the present invention, if the clay is contained below the above range based on the weight of the entire composition, the thermal stability tends to decrease and the physical properties are insufficiently improved due to insufficient crosslinking, and if the clay is contained beyond the above range, If it is included, excessive crosslinking may actually cause a decrease in physical properties.

Meanwhile, the polymer mixture includes 5 to 15 parts by weight of polyurethane and 1 to 5 parts by weight of maleic anhydride grafted ethylene-butylacrylate copolymer based on 100 parts by weight of thermoplastic resin, for example, based on 100 parts by weight of thermoplastic resin. It may include 8 to 13 parts by weight of polyurethane and 2 to 4 parts by weight of maleic anhydride grafted ethylene-butylacrylate copolymer.

If the polymer mixture contains less than the above ratio of polyurethane based on 100 parts by weight of the thermoplastic resin, heat resistance and elasticity are insufficient, and if it exceeds the above ratio, there is a problem of decreased tensile strength. On the other hand, in the polymer mixture, if the maleic anhydride grafted ethylene-butylacrylate copolymer is less than the above ratio based on 100 parts by weight of the thermoplastic resin, the dispersibility of the components of the resin composition is reduced, causing problems with agglomeration or non-uniform mixing. If the ratio is exceeded, there is a problem that thermal and mechanical properties are reduced.

In the present invention, the cross-linking agent may include an acrylic monomer, a silane compound, and a cyanurate-based compound in a weight ratio of 1 to 3: 1 to 3: 1 to 3, for example, in a weight ratio of 1:1:1. It may include

If the acrylic monomer is included less than the above range, there is a problem that sufficient improvement in physical properties is not obtained, and if it is exceeded, there may be a problem of inhibiting a uniform crosslinking reaction.

If the silane compound is less than the above range, there is a problem in improving mechanical properties and hydrophobicity, and if the silane compound is more than the above range, crosslinking is too high, resulting in poor processability during heat compression molding and injection molding.

If the cyanurate-based compound is contained below the above range, there is a problem of insufficient improvement in physical properties because sufficient crosslinking is not obtained, and if it is exceeded, there may be a problem of deterioration in molding processability due to an increase in the degree of crosslinking upon irradiation. .

According to the present invention, a polymer composite material containing the composition for producing a polymer composite material of the present invention described above is provided. In the present invention, 'polymer composite' may refer to both polymer composites before and after irradiation, and, if necessary, may be divided into polymer composites before irradiation and polymer composites after irradiation.

More specifically, according to another aspect of the present invention, a polymer composite in which the composition for producing a polymer composite of the present invention described above is cured with electron beams may be provided, and the polymer composite of the present invention may be a material for covering electric wires.

According to another aspect of the present invention, obtaining an extrudate by extrusion molding the composition for producing a polymer composite material of the present invention described above; And a method for producing a polymer composite is provided, including the step of irradiating 50 to 250 kGy of radiation to the extrudate.

In the step of obtaining an extrudate by extrusion molding the composition for producing a polymer composite of the present invention described above, the extrusion molding may be interpreted as including injection molding or following such a step, but is not limited thereto, for example It is preferably carried out at a temperature of 170 to 230°C, and more preferably at a temperature of 170 to 200°C. If the extrusion molding temperature is less than 170°C, smooth molding tends to be difficult due to insufficient fluidity, and if it is higher than 230°C, carbonization may occur.

When an extrudate is created by extrusion molding, cooling and/or cutting the extrudate may be subsequently performed. At this time, the cooling method may be, for example, natural cooling at room temperature, cooling using cooling water, etc., but is not particularly limited thereto.

For example, the cooling is preferably performed at a temperature of 5 to 80 ℃, preferably 15 to 70 ℃, and if the cutting is performed at less than 5 ℃, the cutting may be smooth due to excessive strength. There is a problem that it is difficult to perform properly, and if it is performed above 80℃, the viscosity increases, so cutting is not done cleanly and there is a problem of sticking to the cutter.

Subsequently, a step of irradiating the cut extrudate obtained as above with radiation of 50 to 250 kGy, for example, 80 to 120 kGy, is additionally performed, where the radiation dose is, for example, 10 to 75 kGy, preferably Typically, it is 10 to 50 kGy. When the radiation dose is less than 50 kGy, bonding between the components of the composition for producing polymer composites tends to be insufficient, and when it is more than 250 kGy, the crosslinking rate increases, resulting in the problem that extrusion and injection molding are not possible.

At this time, the radiation may be selected from the group consisting of gamma rays, electron beams, ultraviolet rays, and X-rays, and electron beams are preferably used.

Furthermore, the step of irradiating the electron beam is preferably performed with an electron beam energy of 1 to 5 MeV, for example, with an electron beam energy of 2 to 3 MeV. If it is less than the above range, the improvement of physical properties such as flexural strength may be insufficient, and if it exceeds the above range, decomposition of the wood composite may occur and physical properties such as flexural strength may be reduced.

According to the present invention, a polymer composite manufactured by the polymer composite manufacturing method of the present invention as described above can be obtained, and the polymer composite obtained by the present invention has excellent thermal stability and other physical properties of the polymer composite. , It can also be applied for special purposes such as bridging wires.

Hereinafter, the present invention will be described in more detail through specific examples. The following examples are merely examples to aid understanding of the present invention, and the scope of the present invention is not limited thereto.

High Density Polyethylene resin (hereinafter referred to as 'PE' or 'HDPE'), polyurethane (hereinafter referred to as 'PU' or 'U') and Fusabond 250D (hereinafter referred to as 'Fusabond' or a polymer mixture comprising (indicated by 'F'); a crosslinking agent selected from trimethylolpropane trimethacrylate (TMPTMA), 3-(trimethoxysilyl)propylmethacrylate (TMPMA), and triallyl isocyanurate (TAIC); And clay (hereinafter referred to as 'Clay' or 'Cl') was added in the composition shown in Table 1 below, blended in a super mixer, and then extruded at a temperature of 190 to 200°C using a twin extruder (SM Platek). After extrusion, masterbatch petlets were manufactured using a cutting machine.

The pellets obtained in this way were injected using an injection machine (SM Platek, Injection Machine) at an injection temperature (nozzle: 183°C, cylinder 1: 181°C, cylinder 2: 196°C).

Furthermore, cross-linking was performed by irradiating a dose of 100 kGy (25 kGy/cycle) using an electron beam accelerator (2.5. MeV, UELV-10-105). The sample code obtained in this way is referred to below as the composition number shown in Table 1 below.

2. Confirmation of physical properties of polymer composites

(1) Cross-linking rate measurement

A specimen was manufactured to evaluate the physical properties. When manufacturing the specimen, the sample was compressed between the upper and lower plates of a hot press with an upper plate temperature of 180~215℃ and a lower plate temperature of 180~215℃ and waited until sufficiently melted. Slowly apply pressure to increase the pressure until it reaches 25-30 MPa, wait for 5 to 20 minutes, take it out, cool it at room temperature, and obtain a physical property measurement specimen in the form of a sheet with a thickness of 3 mm.

The cross-linking rate was measured five times using the Soxhlet extraction method to obtain the average value. More specifically, after measuring the weight of each specimen, it was placed in xylene and heated at 140°C for 8 hours to remove unreacted material, dried in a vacuum oven for 12 hours, and then naturally dried for 4 hours. The weight of the samples was measured, and the crosslinking rate was measured using each weight.

At this time, the crosslinking rate was calculated using the following equation (1).

Crosslinking rate (%) = (Weight after reaction / Weight before reaction) × 100 ... Equation (1)

Before electron beam irradiation, a cross-linking rate (gelation) of about 18% to 24% was analyzed within the error range in all specimen groups, which is believed to be due to the formation of a physical cross-linked structure due to the melting temperature. Meanwhile, after electron beam irradiation, all groups showed a crosslinking rate (gelation) of about 58% to 62% within the error range (Figure 1(a)). The gelation ratio of the polymer composite before and after electron beam was found to increase more in samples 2 to 6 than in sample 1 (Figure 1(b)).

More specifically, in the case of Samples 1 and 2, the increase in cross-linking rate increased by about 4% from 58% to 72% depending on whether or not clay was mixed when irradiated with electron beam, so it is interpreted that clay increases the cross-linking rate. can do. In the case of samples 1 and 3, the increase in crosslinking increased by about 4% from 58% to 72% depending on the presence or absence of TMPTMA mixed upon electron beam irradiation, which can be interpreted as TMPTMA increasing the crosslinking rate by forming a crosslinking structure inside the polymer. You can. In the case of samples 3 and 4, when mixing the cross-linking agent (TMPTMA) upon electron beam irradiation, the cross-linking rate increased depending on the presence or absence of clay, but the increase decreased by about 5% from 72% to 67%, indicating that the clay is a cross-linked structure of TMPTMA within the polymer. It can be interpreted as hindering formation. In the case of yarns 4 to 6, it was confirmed that when mixing TMPTMA, TMPMA, and TAIC components upon electron beam irradiation, the crosslinking increase rate increased to TAIC > TMPMA > TMPTMA, which was determined by electron beam irradiation depending on the number of functional groups of the acrylates of TMPMA, TMPTMA, and TAIC. This can be interpreted as affecting the formation of a cross-linked structure.

(2) Tensile strength and elongation

To confirm the tensile strength and elongation of each specimen, they were measured using a universal testing machine (UTM, Instron 5982, Norfolk, MA, USA). The specimen was measured according to ASTM D638 standard.

The tensile stress of all specimens before and after electron beam irradiation was measured to be about 35 to 36 MPa, and a slight increase in the overall error range was confirmed after electron beam irradiation (Figure 2(a)).

Meanwhile, it was confirmed that the tensile elongation (elongation) of all specimens decreased after electron beam irradiation. In this way, it was experimentally proven that a cross-linked structure was formed in the spray chain of uncross-linked HDPE when irradiated with electron beam (Figure 2(b)). Additionally, when looking at the elongation of the polymer composite specimen before and after electron beam, Sample 2 was higher than that of Sample 1. In the case of samples 1 and 2, the elongation rate increased from about 489% to 365% depending on the presence or absence of clay mixing when irradiated with electron beam, as the decrease amount increased in samples 1 to 6. It can be interpreted that the clay increases the cross-linking structure formation and cross-linking rate. In the case of samples 1 and 3, the increase in cross-linking decreased from 489% to 449% depending on whether TMPTMA was mixed or not when irradiated with electron beam. It is thought that TMPTMA increases the cross-linking rate by forming a cross-linked structure inside the polymer, but the effect was found to be less than that of clay.

(3) Flexural modulus of elasticity

In order to check the flexural modulus of each specimen, a universal testing machine (UTM, Instron 5982, Norfolk, MA, USA) was used to measure the flexural modulus obtained during stress deformation when a standard bent specimen was fixed to both clamps and bent at a constant speed. did. The specimens were measured according to ASTM D790 standards.

As can be seen in Figure 3, it was confirmed that the flexural modulus increased with the addition of the crosslinking agent component of the present invention. In the case of Samples 1 and 2, which did not contain a cross-linker, the flexural modulus decreased due to the decomposition of the polymer among the sample components after electron beam irradiation, but in the case of Samples 3, 4, 5, and 6, the flexural elastic modulus decreased due to the formation of a cross-linked structure between the polymer and the cross-linker upon electron beam irradiation. This is believed to be because the flexural modulus increased due to the excellent tensile properties. In addition, it was confirmed that the flexural modulus can be controlled depending on the type of crosslinking agent.

(4) Thermal stability (Char formation)

To measure the thermal safety of each specimen, each sample was placed in an aluminum pan using a thermogravimetric analysis (TGA), and then measured under nitrogen conditions from 25°C to 800°C at 10°C/min.

It was confirmed that the thermal safety of composite specimens containing clay increased before and after electron beam irradiation, and the results are shown in Figure 4. Figure 4(a) shows the glass transition temperature (Tg) of samples 1, 7, 8, 9, and 10 before electron beam irradiation, and Figure 4(b) shows the glass transition temperature of samples 1, 7, 8, and 9. and 10 shows the glass transition temperature of the specimen after electron beam irradiation.

Referring to Figure 4(c), in the case of samples 1, 7, 8, 9, and 10, char formation increases depending on whether or not the cross-linking agent component is mixed when irradiated with electron beam, and the cross-linking agent component and clay of the present invention It was confirmed that thermal stability was improved by increasing the cross-linking rate by forming a cross-linked structure inside the polymer. Referring to Figure 4, it can be interpreted that the thermal stability of the polymer composite of the present invention is improved rapidly and the thermal stability is rapidly increased due to the formation of a cross-linked structure within the overall composition including clay and cross-linking components.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and variations are possible without departing from the technical spirit of the present invention as set forth in the claims. This will be self-evident to those with ordinary knowledge in the field.
