Performance evaluation of synthesized acrylic acid grafted polyethylene in aluminum hydroxide highly filled polyethylene composites

Abstract

A polymeric agent acrylic acid grafted polyethylene (AAgPE) was synthesized and used as a coupling agent in aluminum hydroxide [Al(OH) 3 ] highly filled linear low-density polyethylene (LLDPE) composite. It is found that AAgPE improves the interfacial adhesion between the filler and the polyethylene matrix, which results in good mechanical properties of the composite. Silicon oil is an effective additive for improving the impact strength, the elongation at break, and the rheological property of the filled composite, but it decreases the tensile strength remarkably.The combination of AAgPE and silicon oil can lead to good performance of the composite. Flammability properties and fracture surface morphologies of the composites through scanning electron microscopy were investigated. The relationship between mechanical properties and microstructure of the composites was discussed

Morphology development of PP/POE blends with high loading of magnesium hydroxide

“…In a typical dual phase co-continuous structure, two phases interpenetrate with each other, suggesting that both phases remain continuous throughout the material [9,11,13] , and the resulting 45 microstructure in such blends enables each phase to share in the load bearing capability of the material [2,3,13] . This somewhat reduces the need for efficient stress transfer between the phases required in dispersed phase blends; and this type of morphology has been observed in various polymer blends under the proper 50 conditions. Varied research has been done to investigate the cocontinuous structured polymer composites via various techniques, including the solvent extraction technique, microscopy, and rheological analysis [11,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] .…”

“…Unfortunately, the addition of the metal hydroxides into polymers to meet the flame-retardant requirement is always extremely high, and the addition of high amounts of inorganic fillers would unavoidably deteriorate the mechanical properties of the resulting materials. Elongation at break is especially affected 55 due primarily to the poor interfacial adhesion between the two components [50][51][52][53] . However, in certain fields of industrial application, such as the material selection for wire and cable use, 10-15 MPa tensile strength and elongation at break larger than 150 % is basically prerequisite.…”

Effect of Interfacial Interaction on Properties of Gamma Ray-Irradiated High Density Polyethylene Reinforced by Sericite-Tridymite-Cristobalite

“…In order to achieve high performance of polymer composites, the matrix-filler interfacial interaction needs to be improved. The method of introducing either the polar group to polymer chain or bridging polymer and filler by the third component=coupling agent could improve the dispersion of fillers in polyethylene matrix and the interfacial interaction between filler and polyethylene matrix [5][6][7][8] .…”

Preparation and properties of flame retardant high impact polystyrene

“…However, the fire safety levels of these nanocomposites cannot meet the requirements of UL 94 V tests. Extensive work has also been carried out to investigate the flame retardant properties of aluminum trihydrate, magnesium hydroxide, and some phosphorous compounds [24][25][26][27][28][29], which sometimes replace halogenated compounds as flame retardants and smoke suppressant fillers for thermoplastics.…”
