人民解放軍 PLA（ポリ乳酸）はポリ乳酸とも呼ばれ、ポリ乳酸の製造プロセスは無公害であり、生成物は生分解性で自然界でのリサイクルが可能であるため、理想的なグリーンポリマー素材であり、代表的なものの一つです。生分解性プラスチック。 PLA の構造は、その耐熱性、靭性、機械的強度、分解性、生体適合性に重要な影響を与えます。以下、耐熱性への影響を中心に説明します。 PLA分子の主鎖にはサブメチレンが1つしかなく、分子鎖がらせん構造をしており、活性が低い。そのため、射出成形後のPLAは結晶化速度が遅いためほとんど結晶化せず、製品の耐熱性が劣ります。熱処理中にエステル結合が部分的に切断されて末端カルボキシル基が生成され、これが PLA の熱劣化に対して自己触媒分解効果をもたらします。 LGF強化PLA The rigidity of the fiber makes it play the role of skeleton support in the polymer matrix. When the polymer is heated, the movement of the chain segment is limited, thus improving the heat resistance of the material. At present, the fibers that can be used for enhancement modification of PLA include natural plant fiber (sisal, flax, linen, bamboo, coconut, wood fiber, etc.), natural animal fiber (silk, etc.), mineral fiber (basalt fiber, etc.), and chemical fiber (carbon fiber, glass fiber, etc.). Among these fibers, carbon fiber and glass fiber are widely used for their high strength and high modulus. Natural plant fiber has been widely studied because of its wide source, degradability and improved thermal and mechanical properties of composites. Modified natural fiber and modified inorganic fiber (glass fiber or carbon fiber) were mixed into the PLA matrix to prepare two kinds of fiber reinforced PLA composites. The test results show that the Vica softening temperature of the composites exceeds 140℃. Compared with Short fiber(SGF) Compared with the short fiber, it has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.
