▎ 摘　　要

NOVELTY - Impact-resistant lightweight foam material comprises 50-200 pts. wt. polyvinylidene fluoride (PVDF), 50-200 pts. wt. thermoplastic polymer, 50-100 pts. wt. light agent, 10-100 pts. wt. filler, 1-10 pts. wt. plasticizer and 1-5 pts. wt. antioxidant. USE - The impact-resistant lightweight foam material is used in petrochemical industry, electronic appliance, fluorocarbon coating, building, automobile and household appliance shell. ADVANTAGE - The material has uniform pore size, strong structure, good pore shrinkage and rebound resilience when impacted, with a certain memory function, and is capable of bearing large degree of external impact. It has light weight, good wear resistance, long use abrasion, suitable for pipeline, pipeline fittings, preparation of film material, especially the preparation material of luggage case. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the impact-resistant lightweight foam material, comprising melting and blending the prepared raw materials at 100-400°C, placing in a reaction kettle after shaping, adding water, increasing the temperature and the pressure, and reacting.
