Description
【発明の詳細な説明】 この発明は合成樹脂成形材料に関するものである。[Detailed description of the invention] This invention relates to synthetic resin molding materials.
一般に、電子部品製造用の合成樹脂成形材料や積層板製
造用の合成樹脂成形材料には、難燃材が配合されている
。Generally, flame retardants are blended into synthetic resin molding materials for manufacturing electronic parts and synthetic resin molding materials for manufacturing laminates.
このような合成樹脂成形材料（以下「成形材料」と略す
）のうち、ハロゲン系難燃剤が配合されている成形材料
にはつぎのような難点があつた。すなわち、この成形材

によつて接点部分の金属や端子金属等の金属材料の腐食
が起こり、それらの性能が低下していた。例えば、接点
においては、接触抵抗の増加が起こつていた。そのため
、このような問題の起こらない成形材料の実現が強く求
められていた。この発明は、このような事情に鑑みなさ

樹脂成形材料であつて、ハロゲンによる腐食を防止する
ために、合成樹脂の一部としてカテコール樹脂を用いる
ことを特徴とする合成樹脂成形材料をその要旨とするも
のである。Among such synthetic resin molding materials (hereinafter abbreviated as "molding materials"), molding materials containing halogen flame retardants have the following disadvantages. In other words, this molding material generates halogen radicals (e.g. Br, Cl) when plastic molded products (electronic parts, laminates, etc.) made using it are heated (pyrolyzed), and these halogen radicals are corrosive. Since hydrogen halides are rich in hydrogen, they have the disadvantage of causing corrosion of surrounding objects, such as metal materials such as contacts. Therefore, when electronic parts made using such molding materials are heated, hydrogen halide causes corrosion of metal materials such as contact metals and terminal metals, reducing their performance. Ta. For example, at contacts, an increase in contact resistance has occurred. Therefore, there has been a strong demand for a molding material that does not cause such problems. This invention was made in view of the above circumstances, and is a synthetic resin molding material containing halogen-based flame retardants, in which catechol resin is added as part of the synthetic resin to prevent corrosion caused by halogens. The gist thereof is a synthetic resin molding material characterized by the use of.
すなわち、この成形材料には、カテコール樹脂が用いら

捉作用をもつ０−ベンゾキノンを発生してラジカルを捕
捉し、腐食性に富むハロゲン化水素の発生を阻止するた
め、上記のような問題の発生が防がれるのである。In other words, catechol resin is used in this molding material, and when heated, this catechol resin generates 0-benzoquinone, which has a radical-scavenging effect, traps radicals and prevents the generation of highly corrosive hydrogen halides. This prevents the above problems from occurring.
成形材料中に配合されるハロゲン系難燃剤類としては、
例えば下記の式で示されるようなハロゲン系難燃剤があ
げられる。Halogen flame retardants that are mixed into molding materials include:
For example, halogen flame retardants as shown by the following formula can be mentioned.
・作ミ干・
（テトラブロモビスフェノールＡ）
（テトラクロロ無水フタル酸）
（テトラブロモ無水フタル酸）
また、上記のもの以外に、臭素化ジフェニルエーテル、
塩素化ジフェニルエーテル等もあげられる。・Sakumiboshi・ (Tetrabromobisphenol A) (Tetrachlorophthalic anhydride) (Tetrabromophthalic anhydride) In addition to the above, brominated diphenyl ether,
Also included are chlorinated diphenyl ethers and the like.
カテコール樹脂は、加熱されると、ｏ−ベンゾキノン，
フェノール，カテコール，ｏ−メトキシフェニル等を生
成する。When catechol resin is heated, o-benzoquinone,
Produces phenol, catechol, o-methoxyphenyl, etc.
これらの生成物のうち、下記の式で表わされるｏ−ベン
ゾキノンは、ラジカル捕捉剤であり、加熱時にハロゲン
系難燃剤類から発生するハロゲンラジカルを捕捉して不
活性化する作用を発揮する。Among these products, o-benzoquinone represented by the following formula is a radical scavenger, and exhibits the effect of capturing and inactivating halogen radicals generated from halogen flame retardants upon heating.
その結果、ハロゲン化水素の発生が阻止されるのである
。カテコール樹脂の使用量は、ハロゲン系難燃剤＊１類
に対してカテコール樹脂が等量以上になるように選ぶこ
とが好ましい。As a result, generation of hydrogen halide is prevented. The amount of catechol resin to be used is preferably selected so that the amount of catechol resin is equal to or more than the amount of halogen flame retardant*1.
カテコール樹脂の使用量が、等量よりも下まわると効果
が不充分になる傾向がみられるからである。成形材料に
用いられる合成樹脂としては、フェノール樹脂、ポリア
ミド樹脂等があげられる。This is because if the amount of catechol resin used is less than the equivalent amount, the effect tends to be insufficient. Examples of synthetic resins used as molding materials include phenol resins and polyamide resins.
なお、この発明の合成樹脂成形材料は、合成樹脂として
、カテコール樹脂だけを用いて構成してもよいのである
。この発明の成形材料の製造は、上記のような原料およ
び必要な場合にはそれ以外の原料を用い、公知の方法に
よつて行われるのである。Note that the synthetic resin molding material of the present invention may be constructed using only catechol resin as the synthetic resin. The molding material of the present invention is produced by a known method using the above-mentioned raw materials and, if necessary, other raw materials.
このようにして得られた成形材料は、加熱時にハロゲン
化水素を発生することのない成形品をつ７くりうるため
、電子部品用等として最適である。The molding material thus obtained can be used to produce molded products that do not generate hydrogen halide during heating, and is therefore ideal for use in electronic parts and the like.
つぎに、実施例について比較例と併せて説明する。次表

類ならびにカテコール樹脂を同表にＬ示す割合で配合し
た。Next, examples will be described together with comparative examples. The base phenol resin, halogen flame retardants, and catechol resin shown in the following table were blended in the proportions shown in the table.
