Description
【0001】
【産業上の利用分野】
本発明は環境問題のない、ハロゲンを含まない熱可塑性樹脂組成物に関し、特にオレフィン系樹脂とスチレンアクリロニトリル系共重合体との混合系における相互分散性と、顔料分散性を高めるために、エポキシ化したジエン系ブロック共重合体とグリシジル基含有共重合体を添加した熱可塑性樹脂組成物に関する。
【0002】
【従来の技術】
塩化ビニル系樹脂は、玩具、文房具、雨具、装丁物、あるいはその他雑貨類、日用品の包装の用途に、又自動車向けでは、内装パネル等の装備品、座席カバー等の表皮材として、フィルム、シート状の形態(以下ではシートという)で利用されているが、塩化ビニル系樹脂がこれらの用途に好適である性質の1つは、塩ビシートの高周波(HF)ウエルダー加工が容易であることにある。
【0003】
しかしこのような塩化ビニル系組成物はハロゲン(塩素)を含有しており、このポリ塩化ビニルを素材とする製品を廃棄、焼却する際、塩酸ガスが発生するため、大気を汚染する。従って、環境汚染することなく、塩化ビニル樹脂の有する高周波ウエルダー特性を保持したポリ塩化ビニルの代替材料の出現が切望されている。
【0004】
ポリ塩化ビニルを含まない樹脂組成物は高周波ウエルダー特性を付与するために、特開平6ー80838ではエチレンーエチルアクリレートー無水マレイン酸共重合体を配合することを、また特開平8ー302144ではスチレンアクリロニトリル系共重合体を配合することが提案されている。しかしながら、これらを配合した組成物では溶融混合性(分散性)が悪く、そのためにウエルダー特性、成形加工性、シートにした時の成形品の物性と外観等のバランスが十分に満たされるものではなかった。
【0005】
又、上記の欠点を補うためにαーオレフィンとα,β−不飽和酸のグリシジルエステルからなるグリシジル基含有共重合体を配合することが提案されているが、引裂き強度が低い等の物性に問題があり、これもまたシ−トやフィルムにしたときの成形外観などのバランスが十分に満たされるものではなかった。
【0006】
【発明が解決しようとする課題】
そこで本発明は、従来の塩化ビニル代替材料の問題点を解決し、ウエルダー特性、成形加工性、シートにした時の成形品外観等のバランスに優れる熱可塑性樹脂組成物を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明者らは、上記課題を解決すべく鋭意研究した結果、特定の樹脂組成物から成る樹脂組成物がウエルダー特性、成形加工性、シートにした時の成形品外観等のバランスに優れることを見出し、本発明を完成した。

即ち、本発明は、(A)オレフィン系熱可塑性樹脂、99〜1wt%と、(B)アクリロニトリル−スチレン−アルキル(メタ)アクリレ−ト系共重合体の1〜99wt%を含有する樹脂組成物100重量部(A+B)に対して、(C)エポキシ化したジエン系ブロック共重合体1〜30重量部、(D)αーオレフィンとα,β−不飽和酸のグリシジルエステルからなるグリシジル基含有共重合体1〜30重量部を配合した熱可塑性樹脂組成物に関し、該組成物は、非常に溶融混合性(分散性)が良いため物性低下もなく、そのためにHFウエルダ−特性、成形加工性、シ−トやフィルムにした時の着色性がよいので、成形品の物性と外観などのバランスが十分に満たされることを発見した。

The copolymerization amount of the glycidyl ester of α, β-unsaturated acid in the glycidyl group-containing copolymer is suitably 1 to 50% by weight, particularly 2 to 30% by weight. Further, if it is 40% by weight or less, unsaturated monomers copolymerizable with the above copolymer, that is, vinyl esters such as vinyl ethers, vinyl acetate and vinyl propionate, acrylic acid such as methyl, ethyl, propyl and butyl. One or more methacrylic acid esters, acrylonitrile, styrene, carbon monoxide and the like may be copolymerized.
The glycidyl group-containing copolymer can be produced by a known technique such as JP-A-47-23490 and JP-A-48-11388, and is commercially available under the trade name Bond manufactured by Sumitomo Chemical Co., Ltd. First etc. correspond to this.
[0026]
To the resin composition of the present invention, fibrous and granular fillers and reinforcing agents, antioxidants and heat stabilizers (for example, hindered phenols, hydroquinones, thioethers, phosphites) to the extent that the object of the present invention is not impaired. And ultraviolet light absorbers, lubricants and mold release agents, dyes and pigments, flame retardants, and the like may be added. In sheet forming, it is possible to add foaming products using a heating foaming agent for vinyl chloride, extrude onto a sheet on another support, lamination, etc., and these sheet forming The technology is described in, for example, JP-A-8-20661.

【Example】
Example 1
A resin compound having the composition shown in Table 1 below was kneaded for 10 minutes under the conditions of a temperature of 140 ° C. and a rotation speed of 100 rpm using a lab plast mill, and then the compound was taken out and 0.5 mm with two rolls. The sheet was molded and examined for suitability for HF welder, moldability, molding appearance when formed into a sheet or film, tear strength, and colorability. The results are as shown in Table 2.

[Comparative example]
Comparative Example 1
In the above Example 1, the physical properties of the sheet were measured in the same manner as in Example 1 except that the epoxidized diene block copolymer was deleted from the resin blend.
The sample was molded into a 0.5 mm sheet with two rolls, and the HF welder characteristics, molding processability, molding appearance when formed into a sheet or film, tear strength, and colorability were examined. The results are as shown in Table 2.
[0031]
Comparative Example 2
In Example 1 above, the physical properties of the sheet were measured in the same manner as in Example 1 except that the glycidyl group-containing copolymer was deleted from the resin blend.
The sample was molded into a 0.5 mm sheet with two rolls, and the HF welder characteristics, molding processability, molding appearance when formed into a sheet or film, tear strength, and colorability were examined. The results are shown in Table 2.
[0032]
The molded appearance was evaluated according to the following evaluation criteria.
○: A clean sheet or film without unevenness was obtained when it was made into a sheet or film.
Δ: Slight irregularities are observed when a sheet or film is formed.
X: Concavities and convexities are conspicuous when formed into a sheet or film.
[0033]
The colored raw material was evaluated according to the following evaluation criteria.
○: No uneven color occurs.
Δ: Color unevenness is observed.
X: The occurrence of uneven color is remarkable.
[0034]
【The invention's effect】
The present invention can be a substitute for polyvinyl chloride with high frequency (HF) welder suitability without environmental pollution.
