Description

Thermoplastic resin composition and molded article formed therefrom

[0001] The present invention relates to a thermoplastic resin composition and a molded article formed therefrom. More specifically, the present invention relates to a thermoplastic resin composition having excellent metal bonding properties, impact resistance, fluidity, and a balance of these properties, and a molded article formed therefrom.

[0002]

[0003] Polyaryl ether ketone (PAEK) resins, such as polyether ether ketone (PEEK) resins, have excellent heat resistance, chemical resistance, rigidity, and fatigue resistance, and are used in fields such as office automation equipment and automobiles.

[0004] However, polyaryl ether ketone resin has a problem of reduced metal bonding strength due to lack of fluidity, which limits its use as a metal bonding material, and has low impact resistance, which limits its application in fields requiring impact resistance, etc.

[0005] In order to improve the impact resistance of polyaryl ether ketone resin, a method of blending polyaryl ether sulfone (PAES) resin is being used. However, due to the limited miscibility of polyaryl ether ketone resin and polyaryl ether sulfone resin blend, there is a concern that mechanical properties may deteriorate.

[0006] Therefore, there is a need to develop a thermoplastic resin composition with excellent metal bonding properties, impact resistance, fluidity, and a balance of these properties.

[0034]

[0035] Hereinafter, the present invention will be described in detail as follows.

[0036] A thermoplastic resin composition according to the present invention comprises (A) a polyaryletherketone resin including two types of polyetheretherketone resins having different melting temperatures (Tm); (B) a polyarylethersulfone resin; and (C) glass fiber.

[0037]

[0038] (A) Polyaryletherketone resin

[0039] A polyaryl ether ketone resin according to one specific example of the present invention can be applied together with a polyaryl ether sulfone resin and glass fiber, etc., to improve the metal bonding property, impact resistance, fluidity, and physical property balance of a thermoplastic resin composition, and includes (A1) a first polyether ether ketone resin having a melting temperature of about 330 to about 350°C, and (A2) a second polyether ether ketone resin having a melting temperature of about 300 to about 325°C.

[0040] (A1) First polyetheretherketone resin

[0041] According to one specific example of the present invention, the first polyether ether ketone resin may have a melting temperature (Tm) of about 330 to about 350°C, for example, about 335 to about 345°C, as measured using a differential scanning calorimeter at a heating rate of 20°C / min. When the melting temperature of the first polyether ether ketone resin is less than about 330°C, there is a concern that the metal bonding properties, fluidity, heat resistance, etc. of the thermoplastic resin composition may deteriorate, and when it exceeds about 350°C, there is a concern that the impact resistance, rigidity (tensile strength, etc.) of the thermoplastic resin composition may deteriorate.

[0042] In a specific example, the first polyetheretherketone resin may include a repeating unit represented by the following chemical formula 1.

[0043] [Chemical Formula 1]

[0044]

[0045] In a specific example, the first polyetheretherketone resin is 1 H-NMR spectroscopy (hydrogen nuclear magnetic resonance spectroscopy; 1The ratio of ketone groups and ether groups measured through H nuclear magnetic resonance spectroscopy may be about 1:1 to about 1:3. In the above range, the impact resistance, processability (flowability), etc. of the thermoplastic resin composition may be excellent.

[0046] In a specific example, the first polyetheretherketone resin is prepared at a temperature of 400°C and for 1,000 sec according to ISO 11443. -1 The melt viscosity measured by a capillary viscometer under shear rate conditions may be about 50 to about 200 Pa·s, for example, about 50 to about 150 Pa·s. Within this range, the thermoplastic resin composition may have excellent metal bonding properties, fluidity, heat resistance, etc.

[0047] In a specific example, the first polyetheretherketone resin may have a weight average molecular weight (Mw) measured by gel permeation chromatography (GPC) of about 60,000 to about 90,000 g / mol, for example, about 70,000 to about 80,000 g / mol. The thermoplastic resin composition may have excellent impact resistance, rigidity, etc.

[0048] In a specific example, the first polyetheretherketone resin may be included in an amount of about 30 to about 70 wt%, for example, about 40 to about 60 wt%, of the total 100 wt% of the polyaryl ether ketone resin including the first polyetheretherketone resin and the second polyetheretherketone resin. In this range, the metal bonding property, rigidity (flexural modulus, etc.) of the thermoplastic resin composition may be excellent.

[0050] According to one specific example of the present invention, the second polyether ether ketone resin may have a melting temperature (Tm) of about 300 to about 325°C, for example, about 300 to about 315°C, as measured using a differential scanning calorimeter at a heating rate of 20°C / min. When the melting temperature of the first polyether ether ketone resin is less than about 300°C, there is a concern that the heat resistance, processability (fluidity), etc. of the thermoplastic resin composition may be reduced, and when it exceeds about 325°C, there is a concern that the metal bonding property, fluidity (injection moldability), etc. of the thermoplastic resin composition may be reduced.

[0051] In a specific example, the second polyetheretherketone resin may include a repeating unit represented by the following chemical formula 1.

[0052] [Chemical Formula 1]

[0053]

[0054] In a specific example, the second polyetheretherketone resin is 1 H-NMR spectroscopy (hydrogen nuclear magnetic resonance spectroscopy; 1 The ratio of ketone groups and ether groups measured through H nuclear magnetic resonance spectroscopy may be about 1:1 to about 1:1.9. In the above range, the thermoplastic resin composition may have excellent metal bonding properties, fluidity, impact resistance, etc.

[0055] In a specific example, the second polyetheretherketone resin is prepared at a temperature of 340°C and for 1,000 sec according to ISO 11443. -1 The melt viscosity measured by a capillary viscometer under shear rate conditions may be about 200 to about 500 Pa·s, for example, about 200 to about 300 Pa·s. Within this range, the thermoplastic resin composition may exhibit excellent impact resistance, metal bonding properties, fluidity, etc.

[0056] In a specific example, the second polyetheretherketone resin may have a weight average molecular weight (Mw) measured by gel permeation chromatography (GPC) of about 50,000 to about 80,000 g / mol, for example, about 60,000 to about 70,000 g / mol. The thermoplastic resin composition may have excellent impact resistance, fluidity, etc.

[0057] In a specific example, the second polyetheretherketone resin may be included in an amount of about 30 to about 70 wt%, for example, about 40 to about 60 wt%, of the total 100 wt% of the polyaryl ether ketone resin including the first polyetheretherketone resin and the second polyetheretherketone resin. Within this range, the metal bonding property, rigidity (flexural modulus, etc.) of the thermoplastic resin composition may be excellent.

[0058]

[0059] (B) Polyaryl ether sulfone resin

[0060] The polyaryl ether sulfone resin according to one specific example of the present invention can be applied together with the polyaryl ether ketone resin and glass fiber, etc., to improve the metal bonding property, impact resistance, fluidity, and physical property balance of the thermoplastic resin composition, and a polyaryl ether sulfone resin used in a typical thermoplastic resin composition can be used.

[0061] In a specific example, the polyarylethersulfone resin may be a polyarylethersulfone resin (e.g., polyphenylsulfone resin) containing a repeating unit represented by the following chemical formula 2.

[0062] [Chemical Formula 2]

[0063]

[0064] In a specific example, the polyaryl ether sulfone resin is prepared at a temperature of 400°C and for 1000 sec according to ASTM D3835. -1The melt viscosity measured by a capillary viscometer under shear rate conditions may be about 200 to about 400 Pa·s, for example, about 210 to about 390 Pa·s. In this range, the fluidity, etc., of the thermoplastic resin composition may be excellent.

[0065] In a specific example, the polyaryl ether sulfone resin may be included in an amount of about 10 to about 45 parts by weight, for example, about 15 to about 40 parts by weight, relative to about 100 parts by weight of the polyaryl ether ketone resin. If the content of the polyaryl ether sulfone resin is less than about 10 parts by weight relative to about 100 parts by weight of the polyaryl ether ketone resin, there is a concern that the metal bonding properties of the thermoplastic resin composition may be reduced, and if it exceeds about 45 parts by weight, there is a concern that the impact resistance of the thermoplastic resin composition may be reduced.

[0066]

[0067] (C) Glass fiber

[0068] According to one specific example of the present invention, glass fiber can be applied together with the polyaryl ether ketone resin and the polyaryl ether sulfone resin to improve the metal bonding property, impact resistance, fluidity, and balance of these physical properties of the thermoplastic resin composition, and glass fiber used in a typical thermoplastic resin composition can be used.

[0069] In specific embodiments, the glass fibers may have various shapes, such as fiber-like, particle-like, rod-like, needle-like, flake-like, and amorphous, and may have various cross-sections, such as circular, oval, and rectangular. For example, the use of fibrous glass fibers having circular and / or rectangular cross-sections may be preferable in terms of mechanical properties.

[0070] In a specific example, the glass fiber having a circular cross-section may have a cross-sectional diameter of about 5 to about 20 μm and a length before processing of about 2 to about 20 mm, and the glass fiber having a rectangular cross-section may have an aspect ratio of the cross-section (ratio of the minor diameter of the cross-section to the major diameter of the cross-section) of about 1.5 to about 10, a minor diameter of the cross-section may be about 2 to about 10 μm, and a length before processing of about 2 to about 20 mm. In the above range, the rigidity (flexural modulus, etc.), metal bonding properties, etc. of the thermoplastic resin composition may be improved.

[0071] In a specific example, the glass fiber may be included in an amount of about 10 to about 60 parts by weight, for example, about 15 to about 50 parts by weight, relative to about 100 parts by weight of the polyaryl ether ketone resin. If the content of the glass fiber is less than about 10 parts by weight relative to about 100 parts by weight of the polyaryl ether ketone resin, there is a concern that the impact resistance, rigidity, etc. of the thermoplastic resin composition may be reduced, and if it exceeds about 60 parts by weight, there is a concern that the metal bonding property, impact resistance, fluidity, etc. of the thermoplastic resin composition may be reduced.

[0072]

Examples of the additives include, but are not limited to, heat stabilizers, ultraviolet stabilizers, impact modifiers, fillers, flame retardants, anti-drip agents, antioxidants, lubricants, release agents, nucleating agents, pigments, dyes, and mixtures thereof. When the additives are used, the content thereof may be about 0.001 to about 40 parts by weight, for example, about 0.1 to about 20 parts by weight, based on about 100 parts by weight of the polyaryletherketone resin.
