Abstract

The invention relates to a high shock resistance type inflaming retarding antistatic polyvinyl chloride composition and a preparation method thereof. The high shock resistance type inflaming retarding antistatic polyvinyl chloride composition is characterized by comprising the following components in parts by weight: 100 parts of polyvinyl chloride, 5-10 parts of chlorinated polyethylene, 10-18 parts of polyoxyethylene, 3.5-5 parts of stabilizing agent, 0.2-0.5 part of lubricating agent and 0-25 parts of organic or inorganic rigid flexibilizer. All of the components are mixed at a high speed, stirred for cooling at a low speed, melt for mixing, hot-cut and air-cooled to obtain blending composition granules. The high shock resistance type inflaming retarding antistatic rigid polyvinyl chloride blending composition adopts a traditional physical blending method, has simple preparation process, and is easy to control. After test, the surface resistance value of the high shock resistance type inflaming retarding antistatic polyvinyl chloride composition is less than 3*10<8> omega, and the shock strength is larger than 35KJ / m<2>. The invention provides the rigid polyvinyl chloride composition having inflaming retarding, permanent antistatic properties and high shock strength and being capable of keeping the antistatic properties under the condition of any humidity.

Problems solved by technology

However, although these measures can eliminate the accumulated static charge on the surface of polyvinyl chloride materials to a certain extent or during the period (Patent No. ZL 91107954; ZL 96102654.5; Engineering Plastics Application, 2004, 32 (2), 41~42; Synthetic resin and Plastics, 2010, 27(1), 10~12), but there are always some problems: (1) Since the ionic antistatic agent has a certain migration ability inside the rigid PVC, it is compatible with PVC and has a tendency to The speed of surface migration is an important factor affecting the performance of blend compositions

Therefore, its blend composition generally has the disadvantages of poor antistatic effect and strong dependence on environmental humidity. In the case of low humidity, it is difficult to meet the antistatic requirements; at the same time, during the entire service life of rigid polyvinyl chloride materials , these ionic antistatic agents will gradually migrate to the surface and disappear, making the rigid PVC blend lose its antistatic properties during its service life

(2) For metal or non-metallic inorganic conductive fillers, a large amount of inorganic conductive fillers need to be added to obtain the required antistatic properties. Due to the compatibility of these conductive fillers with polyvinyl chloride, the interfacial bonding strength is poor, resulting in hard The mechanical properties of high-quality PVC blend compositions, especially the impact strength, are reduced, and their rheological properties are also affected, resulting in deterioration of formability
