Abstract
Description
そこで、これらの課題を克服する材料の組み合わせとして、PCとポリオレフィン樹脂のアロイ、特にポリプロピレン(PP)とPCのアロイが期待されるが、相容化が困難で、そのため面衝撃が弱い、射出成形品に層剥離が生じるなどの大きな課題があり、実際実用化が困難であった。 Polycarbonate resins have high physical properties and good flame retardancy, and are used as important materials for electronic, information and electrical parts. However, it has weak points such as low fluidity and poor chemical resistance. Therefore, in the thinning of products, alloying such as PC / ABS alloy (Patent Document 1) and PC / PS is performed to improve fluidity. However, due to the recent pandemic of influenza, etc., various parts such as alcohol disinfection have been frequently cleaned and cleaned, so high chemical resistance is required for electronic, information and electrical parts. Came. However, a conventional PC / ABS or the like has a strong demand for a PC-based material having low chemical resistance, good fluidity, flame retardancy, and high chemical resistance.
Therefore, an alloy of PC and polyolefin resin, especially an alloy of polypropylene (PP) and PC, is expected as a combination of materials to overcome these problems, but it is difficult to achieve compatibility, and therefore, surface impact is weak. Injection molding There were major problems such as delamination of the product, and practical application was difficult.
特許文献3は、PPとPCの相容化剤として、末端に脂肪族OH基を有するPCとエポキシ基含有PPを溶融混練時に用いることを提案したものであるが、エポキシ基含有PPの分子量が小さく、伸びや衝撃強度の改良効果に限界があると共に、成形時に配向を助長し、厳しい折り曲げなどでは剥離が生じる。
特許文献4は、PPとPCの相容化剤として、末端に脂肪族水酸基を有するPCとカルボキシル基含有PPを溶融混練時に用いることを提案したものであるが、その反応効果は十分ではなく、伸びの改良や層剥離防止効果は小さい。
特許文献5は、PPとPCの相容化剤として、SEBSを用いることを提案したものだが、SEBSもPCとの相容性が低く、この方法では、引張伸びの向上や層剥離防止が困難である。
特許文献6は、OH末端PCとエチレン-グリシジルメタクリレート(GMA)の共重合体を溶融混練することにより、低温衝撃性を改善することを提案したものだが、この方法では流動性の改善は殆んど期待できない。また、PPとの組み合わせに関しては、全く考慮されていない。
特許文献7は、酸無水物変性ポリオレフィン(PO)とOH末端PCを反応させた樹脂改質剤が開示されており、そして、本改質剤はPPとPCの相容化剤としても活用できることを提案している。しかし、実際PCとPPの改質剤としての効果は示されておらず、酸無水物変性POとOHの反応は十分ではなく、伸びの改良や層剥離防止効果は小さい。 For example, Patent Document 2 proposes to use a hydrogenated styrene-butadiene-styrene block copolymer epoxidized product (epoxy-modified SEBS) as a compatibilizer for PP and PC. Since it does not have a functional group, it is difficult to improve tensile elongation and prevent delamination by this method.
Patent Document 3 proposes using PC having an aliphatic OH group and an epoxy group-containing PP at the time of melt-kneading as a compatibilizer for PP and PC, but the molecular weight of the epoxy group-containing PP is It is small and has limited effects on improving elongation and impact strength, promotes orientation during molding, and peels off when severely bent.
Patent Document 4 proposes to use PC having an aliphatic hydroxyl group at the terminal and carboxyl group-containing PP as a compatibilizer for PP and PC at the time of melt-kneading, but the reaction effect is not sufficient, The improvement in elongation and the effect of preventing delamination are small.
Patent Document 5 proposes the use of SEBS as a compatibilizer for PP and PC, but SEBS is also poorly compatible with PC, and this method makes it difficult to improve tensile elongation and prevent delamination. It is.
Patent Document 6 proposes to improve low-temperature impact properties by melt-kneading a copolymer of OH-terminated PC and ethylene-glycidyl methacrylate (GMA), but this method hardly improves flowability. I can't expect it. Moreover, no consideration is given to the combination with PP.
Patent Document 7 discloses a resin modifier obtained by reacting acid anhydride-modified polyolefin (PO) with OH-terminated PC, and that this modifier can also be used as a compatibilizer for PP and PC. Has proposed. However, the effect as a modifier for PC and PP is not shown in practice, and the reaction between acid anhydride-modified PO and OH is not sufficient, and the effect of improving elongation and preventing delamination is small.

フィブリル形成能を有するポリテトラフルオロエチレン(PTFE)には特に制限はないが、例えば、ASTM規格において、タイプ3に分類されるものが挙げられる。
その具体例としては、例えば、テフロン6-J[三井・デュポンフロロケミカル(株)製]、ポリフロンD-1、ポリフロンF-103、ポリフロンF201[ダイキン工業(株)製]及びCD076[旭アイシーアイフロロポリマーズ(株)製]等が挙げられる。
また、上記タイプ3に分類されるもの以外では、例えば、アルゴフロンF5(モンテフルオス株式会社製)、ポリフロンMPA及びポリフロンFA-100(ダイキン工業株式会社製)等が挙げられる。

The fluorine-containing polymer as component (F) is usually a polymer or copolymer containing a fluoroethylene structure, such as a difluoroethylene polymer, a tetrafluoroethylene polymer, or a tetrafluoroethylene-hexafluoropropylene copolymer. And a copolymer of tetrafluoroethylene and an ethylene monomer not containing fluorine. Polytetrafluoroethylene (PTFE) is preferable, and the average molecular weight is preferably 500,000 or more, and particularly preferably 500,000 to 10,000,000.
As polytetrafluoroethylene that can be used in the present invention, all of the currently known types can be used. Of polytetrafluoroethylene, those having a fibril-forming ability are preferred.
Although there is no restriction | limiting in particular in the polytetrafluoroethylene (PTFE) which has a fibril formation ability, For example, what is classified into the type 3 in ASTM standard is mentioned.
Specific examples thereof include, for example, Teflon 6-J [Mitsui / DuPont Fluorochemical Co., Ltd.], Polyflon D-1, Polyflon F-103, Polyflon F201 [Daikin Industries, Ltd.] and CD076 [Asahi ICC] Fluoropolymers Co., Ltd.] and the like.
Other than those classified as type 3 above, for example, Algoflon F5 (manufactured by Montefluos Co., Ltd.), polyflon MPA, polyflon FA-100 (manufactured by Daikin Industries, Ltd.) and the like can be mentioned.
These polytetrafluoroethylene (PTFE) may be used independently and may combine 2 or more types.
The polytetrafluoroethylene (PTFE) having the fibril-forming ability as described above is obtained by, for example, using tetrafluoroethylene in an aqueous solvent in the presence of sodium, potassium, ammonium peroxydisulfide, under a pressure of 7 to 700 kPa, at a temperature. It can be obtained by polymerization at 0 to 200 ° C., preferably 20 to 100 ° C.
The fluorine-containing polymer (F) is added for further improvement of flame retardancy (for example, V-0, 5V), and its blending amount is 100 mass of the total amount of the components (A) to (C). 0.05 to 5 parts by mass per part. When the blending amount is less than 0.05 parts by mass, the anti-dripping property is inferior, and when it exceeds 5 parts by mass, the surface appearance and mechanical properties (impact strength) are deteriorated. More preferably, it is in the range of 0.1 to 1 part by mass.
この範囲を外れると、即ち難燃剤量(E)がポリオレフィン量(B+C)の1/3よりも少ないと、難燃性が不足し、UL規格を満足できなくなる。また難燃剤量(E)がポリオレフィン量(B+C)の2倍以上になると、耐薬品性が低下し、一般的な洗浄剤に耐えられなくなる。
ちなみに、上記関係式は、流動性を改良するために添加したポリオレフィン量に対する難燃剤の必要量を割り出したものであり、ULの難燃規格と一般的な洗浄剤に対する耐薬品性と相反する特性に関し、何れも満足するような添加量を詳細な実験結果より誘導したものである。なお、この関係は、ポリカーボネート樹脂中にポリオレフィンを微細に分散させ層剥離を起こさない状態での値であり、層剥離を起こす場合は、難燃性が不足し、両者を満足する添加量は存在しなかった。 Within the range of each component, it is preferable that the components (B), (C), and (E) have a content satisfying the relationship of 1/3 (B + C) <E <2 (B + C).
If it is out of this range, that is, if the amount of flame retardant (E) is less than 1/3 of the amount of polyolefin (B + C), the flame retardancy is insufficient and the UL standard cannot be satisfied. Moreover, when the amount of flame retardant (E) is twice or more than the amount of polyolefin (B + C), the chemical resistance is lowered and it becomes impossible to withstand general cleaning agents.
By the way, the above relational expression is obtained by calculating the necessary amount of flame retardant with respect to the amount of polyolefin added to improve fluidity, and it is a characteristic that contradicts the flame resistance standard of UL and the chemical resistance to general cleaning agents. In this regard, the amount of addition that satisfies both is derived from detailed experimental results. This relationship is the value when polyolefin is finely dispersed in the polycarbonate resin and does not cause delamination. When delamination occurs, the flame retardancy is insufficient, and there is an added amount that satisfies both I did not.
