Method for improving interface bonding of long glass fiber-polyolefin composite material based on non-covalent entanglement

The invention belongs to the field of high polymer materials, and discloses a method for improving interface bonding of a long glass fiber-polyolefin composite material based on non-covalent entanglement, and a long-chain aliphatic silane coupling agent is introduced into the long glass fiber-polyolefin composite material to improve interface bonding of the long glass fiber-polyolefin composite material and the long glass fiber-polyolefin composite material. The long glass fiber impregnated master batch comprises polyolefin, long glass fiber, a novel silane coupling agent mixture or a novel silane coupling agent mixture, an antioxidant, a lubricant and other various functional additives. The polyolefin functional master batch comprises polyolefin, an antioxidant, a lubricant, a novel silane coupling agent mixture or a novel silane coupling agent mixture, and other various functional additives. According to the invention, the interface bonding between the long glass fiber and polyolefin is improved, convenienc
