Anti-aging sisal fiber modified SBS (styrene butadiene styrene) composite material

Abstract

The invention relates to an SBS (styrene butadiene styrene) composite material, in particular to an anti-aging sisal fiber modified SBS composite material, which is characterized by being prepared from the following ingredients in parts by weight: 50 to 70 parts of SBS, 6 to 13 parts of polystyrene, 5 to 10 parts of modified sisal fiber, 2 to 5 parts of ceramic fiber, 0.01 to 0.05 part of spermine-NO, 0.01 to 0.03 part of citric acid, 0.1 to 0.3 part of dioxane, 1 to 3 parts of antioxidants and 0.5 to 1 part of lubricating agents. The invention also provides a preparation method of the SBS composite material. The SBS composite material prepared by the method has the characteristics of excellent anti-aging performance, excellent anti-impact performance and the like.

Description

Technical field

[0001] The present invention relates to the technical field of SBS composite material modification, and more specifically, to a SBS composite material modified by aging resistant sisal fiber. Background technique

[0002] Sisal belongs to the Agave family and is a widely cultivated perennial economical plant. The sisal fiber taken from its leaves has a white color, is resistant to seawater corrosion, has tough texture, low density, high tensile strength and modulus. It has a wide range of sources and low price. Therefore, sisal fiber has obvious advantages for preparing high-strength, high-modulus and inexpensive fiber-reinforced polymer-based composites.

[0003] Styrene-butadiene-styrene block copolymer (SBS) is a block copolymer with styrene as monomer. It has the characteristics of plastic and rubber, has good chemical stability, excellent low-temperature performance, and low price. It is one of the important general-purpose plastics in the industry due to its ...
