Embodiment 1
[0018] A polypropylene toughened corrugated pipe for vehicles, made of the following raw materials in parts by weight: 100 parts of polypropylene (PP K8303), 6 parts of polyethylene octene co-elastomer, tetrabromobisphenol A-bis(2, 3 parts of 3-dibromopropyl ether), 1.5 parts of antimony trioxide, 0.5 part of masterbatch and 2 parts of antioxidant; said antioxidant includes main antioxidant 1010, didodecyl thiomalonate and Antioxidant matrix (polyvinyl chloride), the weight ratio between main antioxidant 1010, didodecyl thiomalonate and antioxidant matrix is 1:3:4.
[0019] Theoretically, adding elastomers such as POE, EVA, etc. can be used to increase the toughness of the product. In order to achieve the ideal toughness of the material, the amount of elastomer (such as POE) should be very strict, because the introduction of POE will inevitably reduce the oxygen index. In order to make the product reach the corresponding UF94 F-V0 The standard flame retardant requirement re...
