Abstract
DC60 (24/06/57) การประดิษฐ์เกี่ยวข้องกับวิธีการสำหรับการเตรียมชุดหลักของไดอีนอีลาสโทเมอร์และซิลิกา ซึ่งประกอบรวมด้วยขั้นตอนตามลำดับต่อไปนี้ - การเตรียมอย่างน้อยที่สุดหนึ่งสารกระจายของซิลิกาในน้ำ, - การนำมาสัมผัสและการผสมอีลาสโทเมอร์ลาเทกซ์และสารกระจายแอคเควียสซิลิกา โดยมีเกลือซิงค์อยู่ด้วย, เพื่อให้ได้มวลจับตัวเป็นก้อน, - การนำกลับคืนมาต่อมวลจับตัวเป็นก้อน, - การทำให้แห้งต่อมวลจับตัวเป็นก้อนซึ่งนำกลับคืนมาเพื่อให้ได้ชุดหลัก; ปริมาณโดยโมลของซิงค์แคทไอออน, กำหนดเป็นจำนวนของโมลของซิงค์แคทไอออนของ เกลือซิงค์ต่อหน่วยของพื้นผิวจำเพาะ BET ของซิลิกา, อยู่ระหว่าง 1.19 x 10ยกกำลัง-6 และ 5.62 x 10ยกกำลัง-6 mol/m2 : DC60 (24/06/14) The invention involved a method for the preparation of primary sets of diene, elastomer and silica. It consists of the following sequential steps - preparation of at least one aqueous silica dispersant, - exposure and mixing of elastomer, latex and actuase dispersant. silica With zinc salt in it, to obtain coagulation mass, - recovery to coagulation mass, - drying to coagulant mass recovered to obtain the main set; Molar quantity of zinc cation, is defined as the number of moles of zinc cation of The zinc salt per unit of the silica BET specific surface, is between 1.19 x 10 to the -6 power and 5.62 x 10 to the -6 mol / m2 power:
