Abstract
กรรมวิธีการเตรียมสารเคลือบผิวจากยางธรรมชาติและพอลิไวนิลคลอไรด์ เป็นการนำน้ำยางธรรมชาติ และพอลิไวนิลคลอไรด์ผสมกับสารเคมี เช่น ซิงค์ออกไซด์, กรดสเตียริก, ไดเบนโซไทอะซิลไดซัลไฟด์, สารยึด เกาะ สารแอนติออกซิแดนท์ และกำมะถัน โดยสารเคมีเหล่านี้จะถูกเติมลงไปในของผสมในรูปลักษณะสารดิส เพอร์ชัน (Dispersion) ทำการผสมสารเคมีให้ของผสมอยู่ในรูปของน้ำยางพรีวัลคาไนซ์ โดยนำไปเคลือบผิว สำหรับผลิตภัณฑ์ที่ป้องกันการดูดซับน้ำหรือผลิตภัณฑ์ที่ต้องการ เช่น กล่องกระดาษ เป็นต้น เนื่องจากวัสดุที่ ใช้ทำผลิตภัณฑ์กระดาษส่วนมากทำมาจากเส้นใยจากเยื่อไม้ ซึ่งเส้นใยจากเยื่อไม้จะมีความเป็นรูพรุนในตัวสูง ทำให้มีคุณสมบัติทางด้านการดูดซับที่ดี จึงทำการป้องกันด้วยการเคลือบผิวผลิตภัณฑ์ เมื่อสารเคลือบผิวแห้ง แล้วจะเกิดเป็นชั้นแผ่นฟิล์มบาง (Thin film) แบบเนื้อแน่น ทำให้ช่วยปกป้องผิวหน้าของผลิตภัณฑ์ไม่ให้สาร หรือไอออนต่างๆ ซึมผ่านไปได้ Process for preparing coating from natural rubber and polyvinyl chloride. Is the introduction of natural latex And polyvinyl chloride mixed with chemicals such as zinc oxide, stearic acid, dibenzothai, acetyl disulfide, binder, antioxidant and sulfur by chemicals. These are added to the mixture as a dispersion (Dispersion), chemical mixing to make the mixture in the form of pre-vulcanized latex. By applying to the surface For products that prevent water absorption or products that require such as paper boxes, because the Used to make paper products, most of them are made from fibers from wood pulp. The fibers from wood pulp have a high porosity. It has good adsorption properties. Therefore doing protection by coating the product surface When the coating is dry Then it will form a thin film (Thin film), tight texture, helping to protect the surface of the product from substances Or various ions are permeable
