Description
本發明係關於一種樹脂組成物,尤指一種可提升熱傳導係數之樹脂組成物。The present invention relates to a resin composition, and more particularly to a resin composition which can increase the heat transfer coefficient.
聚碳酸酯系樹脂具有極佳之模具和塑形能力,因此廣泛應用於日常生活中的各種領域。例如,樹脂組成物可用於製作成筆記型電腦、攜帶型儀器之外殼,而由於設置於其內部之中央處理器(CPU)、記憶體、硬碟等元件係為發熱源,並且隨著筆記型電腦、攜帶型儀器之高速化,使得中央處理器之發熱量會越來越增加,因此散熱問題就顯得更為重要。Polycarbonate resins are widely used in various fields of daily life because of their excellent mold and shape. For example, the resin composition can be used as a casing for a notebook computer or a portable device, and a component such as a central processing unit (CPU), a memory, a hard disk, or the like disposed inside is a heat source, and is attached to a notebook. The high speed of computers and portable instruments makes the heat generated by the central processor more and more, so the heat dissipation problem is even more important.
對於散熱而言,外殼所使用之材料較佳是具有高熱傳導率者,由於一般的樹脂材料熱傳導率都很低,因此就必須探討使用樹脂製外殼時,使外殼散熱之其他方法。For the heat dissipation, the material used for the outer casing is preferably one having a high thermal conductivity. Since the general thermal conductivity of the resin material is low, it is necessary to investigate other methods of dissipating the outer casing when using the resin outer casing.
此外,從環境方面來考量,對應德國或瑞士等國家之環保標籤(Eco Label)之要求,較佳係使用不含有氯或溴等鹵素之阻燃性材料。In addition, from the environmental point of view, it is preferable to use a flame retardant material which does not contain a halogen such as chlorine or bromine, in accordance with the requirements of the Eco Label of a country such as Germany or Switzerland.
例如,日本專利特開2000-349486號中,係揭露一種外殼係對經成形加工熱可塑性樹脂所得到之樹脂成形品的表面進行金屬電鍍,使可得到輕質量且具有高剛硬性、熱傳導性良好及低成本之機器外殼。然而,其使用的磷酸酯系阻燃劑會使得樹脂組成物在成形時氣體之產生量會變多而導致良率低下的問題。For example, Japanese Laid-Open Patent Publication No. 2000-349486 discloses a case in which a surface of a resin molded article obtained by forming a thermoplastic resin is subjected to metal plating to obtain a light weight, high rigidity, and good thermal conductivity. And a low-cost machine casing. However, the phosphate-based flame retardant used therein causes a problem that the amount of gas generated during the molding of the resin composition increases, resulting in a low yield.
有鑑於上述之狀況,本領域需研究開發新的改良配方,使可不斷的提升熱傳導係數,而可具有長的使用壽命,並同時符合環保要求。In view of the above situation, it is necessary to research and develop new and improved formulations in the field, so that the heat transfer coefficient can be continuously improved, and the service life can be long and at the same time meet environmental protection requirements.
