Problems solved by technology

However, the acrylic resin films described in References 26 to 28 do not describe their light back resistance, and the acrylic resin films using the resin composition described in the examples as raw materials do not have any expected light back resistance. A level for building materials, not suitable for laminated films or sheets for building materials
[0049] On the other hand, when an acrylic resin film with excellent heat resistance (for example, references 1 to 4) is used, it is excellent in light reflection resistance, but it is not suitable for use as a laminate for building materials because of poor molding whitening resistance. film or sheet

Embodiment 1

[0781] To 100 parts of the multilayer structure polymer (I-1), 2.7 parts of the product name "Chiubin 234" manufactured by Chiba Special Chemicals Co., Ltd. and 0.1 part of the product name "Adecastab AO-50" manufactured by Asahi Denka Kogyo Co., Ltd. were added as compounding agents. and 0.3 part of the product name "Adecastab LA-57" manufactured by Asahi Denka Co., Ltd., and mixed with a Henschel mixer. This mixture [resin composition (III-1)] was heated to 230°C, supplied to a degassing extruder (PCM-30 (trade name) manufactured by Ikegai Iron Works Co., Ltd.), and kneaded to obtain pellets. .

[0782] The granules produced by the above method are dried at 80°C - day and night, with a 40mm φ non-bending screw extruder (L / D=26) equipped with a 300mm wide T-die, at a barrel temperature of 180-240°C, T Film formation was carried out at a mold temperature of 240° C. to obtain an acrylic resin film (A) having a thickness of 125 μm. Formation of the decorative layer (B) was goo...

Embodiment 2

[0784] In addition to using 90 parts of multilayer structure polymer (I-1) and thermoplastic polymer (II-1) [MMA / MA=99 / 1 (mass ratio), reduced viscosity ηsp / c=0.06L / g] instead of 10 parts Except for 100 parts of the multilayer structure polymer (I-1), a mixture [resin composition (III-2)] was obtained in the same manner as in Example 1, and a film was formed to obtain an acrylic resin film (A). Formation of the decorative layer (B) was good, and there were few printing omissions.

Embodiment 3

[0786] Except using 75 parts of multilayer construction polymers (I-1) and 25 parts of thermoplastic polymers (II-1) to replace 100 parts of multilayer construction polymers (I-1), the mixture [resin Composition (III-3)] was formed into a film to obtain an acrylic resin film (A). Formation of the decorative layer (B) was good, and there were few printing omissions.

Abstract

An acrylic resin film material comprising at least a multilayer structure polymer with a particular structure prevent a molded item from being whitened during insert- or in-mold molding and meet the requirement for surface hardness, heat resistance, and transparency or matting performance for vehicle applications. It is also possible to use an acrylic resin film material exhibiting a difference of 30% or less between haze values as determined in accordance with the testing method of JIS K7136 (haze measurement method) after and before a tensile test where a test piece with a width of 20 mm is pulled under the conditions of an initial inter-chuck distance of 25 mm, a rate of 50 mm / min and a temperature of 23 DEG C. until an end-point inter-chuck distance becomes 33 mm as well as having a pencil hardness of 2 B or higher as determined in accordance with JIS K5400.

Description

technical field [0001] The present invention relates to multilayer structure polymers and resin compositions, acrylic resin films, acrylic resin laminated films, photocurable acrylic resin films and sheets, laminated films and sheets, and laminated moldings in which these are laminated Taste. Background technique [0002] As a method of imparting a pattern to a molded product at low cost, there are insert molding or inmold molding. The insert molding method is to form a film or sheet of polyester resin, polycarbonate resin, acrylic resin, etc. with printing and other decorations into a three-dimensional shape by pre-vacuum forming, remove unnecessary film or sheet parts, and then move it into the injection molding machine. In the molding die, the base resin is injection-molded to obtain an integrated molded product. On the other hand, the in-mold molding method is to place a film or sheet of polyester resin, polycarbonate resin, acrylic resin, etc., which has been decorate...
