一种表面卤化改性硫化橡胶粉／聚氯乙烯共混复合物的制备方法
摘要：
本发明公开了一种表面卤化改性硫化橡胶粉/聚氯乙烯共混复合物的制备方法，其特点是该方法包括以下步骤：将平均粒径≤100μm的硫化橡胶粉100份，溶剂200～500份，卤化剂1.0～10份加入带有搅拌器、温度计和加热装置的反应器中，于温度5～50℃反应0.5～4h，经过滤，干燥，制得表面卤化改性的硫化橡胶粉；再将改性硫化橡胶粉10～50份，聚氯乙烯25～58份，增塑剂25～32份，通过高速搅拌机混合均匀，经平板硫化机在温度180～200℃，压力10～15Mpa热压成型，获得表面卤化改性硫化橡胶粉/聚氯乙烯共混复合物。
摘要（英）：

The invention discloses a preparation method of a surface halogenation modified vulcanized rubber powder/polyvinyl chloride blended compound, which is characterized by comprising the following steps: adding 100 parts of vulcanized rubber powder (of which the average particle size is smaller than or equal to 100 mu m), 200-500 parts of solvent and 1.0-10 parts of halogenating agent into a reactor provided with a stirrer, a thermometer and a heater, reacting at 5-50 DEG C for 0.5-4 hours, filtering, and drying to obtain the surface halogenation modified vulcanized rubber powder; and evenly mixing 10-50 parts of modified vulcanized rubber powder, 25-58 parts of polyvinyl chloride and 25-32 parts of plasticizer in a high-speed mixer, and thermoforming with a flat vulcanizing machine at 180-200 DEG C under the pressure of 10-15Mpa, thereby obtaining the surface halogenation modified vulcanized rubber powder/polyvinyl chloride blended compound.
