preparation example Construction

[0134] Any method may be adopted for the production of the thermoplastic resin composition of the present invention. For example, the method of premixing A component, B component, and other components, melt-kneading, and granulating is mentioned. As the means of premixing, a Nauta (NAUTA) mixer, a V-blender, a Henschel mixer, a mechanochemical device, an extrusion mixer, etc. are mentioned. In premixing, granulation may be performed using an extrusion granulator, a briquetting machine, or the like as needed. After premixing, melt kneading is performed using a melt kneader represented by a vented twin-screw extruder, and granulation is performed using a machine such as a granulator. As the melt-kneading machine, a Banbury mixer, a kneading roll, a constant-temperature stirring vessel, etc. may also be mentioned, but a vented twin-screw extruder is preferable.

[0135] In addition, a method of independently supplying each component to a melt-kneader represented by a twin-screw...

Embodiment 1-11、 comparative example 1-5

[0208] Each evaluation result of Examples 1-11 and Comparative Examples 1-5 is described in Table 1.

[0209] [Table 1]

[0210]

[0211] As shown in Examples 1-11, the resin composition of the present invention has a flexural modulus of 2,200 MPa or more and less than 12,000 MPa as measured in accordance with ISO-178, and the film insert molded product not only has excellent appearance, but also has excellent adhesion, and The impact resistance was excellent, and the deflection temperature under load was high, and no problems occurred in the warm water test.

[0212] Comparing Example 1 and Comparative Example 1, it can be seen that if no impact modifier is incorporated into the film insert molded product, wrinkles will be generated. Comparing Examples 2 and 3 with Comparative Examples 2 and 3, it can be seen that when the components B and C are contained in a large amount, the elastic modulus is 2,200 MPa or less, and the deflection temperature under load is lowered, res...

Abstract

The present invention provides a resin composition for film insert molding and a molded product thereof, namely, a thermoplastic resin composition which can form the molded product of the film insert that has the advantages of excellent rigidity, excellent impact resistance, excellent closing performance and excellent appearance designing performance, and the molded product of the film insert formed by the thermoplastic resin composition. The resin composition for film insert molding is characterized in that: relatively to 100 parts by mass of resin composition which is composed of 100-50wt% of (A) polycarbonate resin (component A) and 0-50wt% of (B) a resin (component B) except for polycarbonate resin, the resin composition comprises 0.1-30 parts by mass of (C) impact modifying material (component C) and 0-30 parts by mass of (D) inorganic filling material (component D). Furthermore the bending elastic modulus obtained according to ISO-178 is above 2,200MPa and less than 12,000MPa.

Description

technical field [0001] The present invention relates to a resin composition suitable for film insert molding excellent in rigidity, impact resistance, adhesion, and design, and to reducing environmental load, number of steps, and cost by eliminating a painting process or a plating process Decorative film insert molded products with excellent rationality. Background technique [0002] The trend of replacing inorganic materials with resin materials is accelerating due to reasons such as weight reduction, design freedom, processability, and cost reduction. In recent years, in the automotive field, office automation (OA) field, and home electric appliances, the thickness reduction and weight reduction of parts are rapidly progressing, and the use of resin materials is increasing. With the thinning of products, high rigidity and impact resistance are required for resin materials, and various resin compositions are provided. [0003] In recent years, the use of various plastic m...
