Abstract
วิธีการทำยาง ซิส 1, 4-โพลีไอโซพรีนที่ได้เอพอกซิไดซ์แล้วจากลาเท็กซ์ของซิส 1,4-โพลีโอโซพรีนชนิดธรรมชาติหรือสังเคราะห์ ที่ประกอบด้วยการทำปฏิกิริยาของลาเท็กซ์ของยางกับกรดเพอร์ฟอร์มิคหรือกรดเพอร์แอซิดที่เกิดขึ้นในที่เป็นการทำให้ลาเท็กซ์จับตัวเป็นก้อน การเติมเบสลงในยางและการล้างสารที่จับตัวเป็นก้อนอย่างทั่วถึงเพื่อขจัดตัวทำปฏิกิริยาที่เหลือตกค้างอยู่ทั้งหมดและส่วนที่ไม่ใช่ยางที่ได้ถูกดัดแปลงแล้วออกได้มากพอ วิธีนี้ได้ทำให้เหมาะสำหรับปฏิบัติการของขนาดทางพานิชย์ที่มี ปฏิกิริยาข้างเคียงน้อยที่สุด เพื่อให้ได้ยางที่ได้เอพอกซิไดซ์ แล้วที่จะใช้เตรียมวัลคานิเซทที่มีคุณสมบัติที่ดี Method for making sis 1, 4-polyisoprene epoxidized rubber from sis latex. 1,4-polyozoprene, natural or synthetic It consists of the reaction of rubber latex with performic acid or peracid that is formed in which the latex coagulates. The addition of bases to the rubber and thorough washing of the coagulation agents remove enough of all residual reagents and modified non-rubber sections. This approach makes it suitable for operations of any commercial scale. minimal side effects to obtain epoxidized rubber And then to use to prepare the vulcaniseate with good properties.
