本発明は異方性溶融相を形成しうる溶融加工性ポリエス

形品の表面処理法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for surface treatment of a melt-processable polyester (hereinafter simply referred to as "liquid crystalline polyester") resin molded product capable of forming an anisotropic melt phase.

品を効率よく得るための表面処理法に関する。More specifically, surface treatment to efficiently obtain liquid crystalline polyester resin molded products with excellent heat resistance and moldability that have surface characteristics suitable for surface decoration by printing, painting, vapor deposition, plating, etc. and adhesion with adhesives. Regarding the law.

断応力を受けるだけで一方向に配向し、液状でも結晶性
を示すいわゆる液晶性を示す。Unlike generally known thermoplastic polyesters such as polybutylene terephthalate and polyethylene terephthalate, liquid crystalline polyester is made of a rigid polymer, and its molecular chains are difficult to bend and maintain a rod shape even in the molten state. It has little entanglement, is oriented in one direction when subjected to a slight shear stress, and exhibits so-called liquid crystallinity, which means that it exhibits crystallinity even in liquid form.

表面は強い配向のため表層部は剥離し毛羽立ちを生じ易
く、そのままでは接着、塗装、メツキによる2次加工が
できない。Although the commonly used injection molding processing method can be applied to such liquid crystalline polyester, the surface of the molded product is highly oriented, so the surface layer tends to peel off and become fluffy, and if left as is, it will not be possible to bond, paint, or plate it. secondary processing is not possible.

ない。Therefore, surface roughening treatment using chemicals such as those conventionally used for general resins may be considered, but the surface is extremely inert chemically and there is no suitable solvent with affinity for the surface layer. It is not possible to remove the alignment layer and roughen the surface.

い。On the other hand, thermally, liquid crystalline polyester exhibits a low linear expansion coefficient comparable to that of general metals, and has characteristics such as heat resistance such as no abnormality even when immersed in a 260°C solder bath for 10 seconds. There has been a need for a surface treatment method that takes advantage of this property and improves the surface properties for applications such as parts bonded to metals with adhesives and plated substrates, but this method has not yet been satisfied. There is no known method of climbing.

、本発明を完成するに至った。[Means for Solving the Problems] The present inventors took advantage of the thermally beneficial characteristics of liquid crystalline polyester to create a material that chemically activates the surface without impairing its physical or chemical properties. As a result of intensive research into a method that does not generate a surface layer that is easy to peel off, molded products made of a composition containing 5 to 80% by weight (based on the total amount of the composition) of a specific inorganic filler in liquid crystalline polyester were prepared using Mietchinda liquid. If a combination of a specific material composition and a specific etching solution is used, such as contact treatment with an aqueous solution containing an alkali metal hydroxide or an alkaline earth metal hydroxide as a main component, liquid crystallinity can be achieved. The present inventors have discovered that the surface workability of polyester resin molded products is significantly improved, and have completed the present invention.

It is 70% by weight. At 5% by weight, uneven flow marks occur on the surface of the molded product, and when the adhesive tape is attached to the surface of the molded product, a thin film easily peels off when the tape is peeled off. Causes unevenness. On the other hand, 8
If it exceeds 0% by weight, the fluidity of the resin will decrease, making it impossible to obtain a molded product with a good surface, causing roughness on the surface due to etching, and at the same time reducing the mechanical strength of the molded product, which is not preferable.
