Pipe strengthening master batch and preparation method thereof

The invention discloses a pipe strengthening master batch and a preparation method thereof, belongs to the technical field of plastic building materials, and aims to overcome the defect that the existing master batch for pipes easily causes insufficient pressure resistance of pipes and pipe fittings. The pipe strengthening master batch comprises the following components in parts by weight: 5-20 parts of a polyolefin resin, 30-80 parts of a filler, 0.1-6 part of a dispersing agent, 0.1-6 part of a processing aid, 0.1-2 part of a coupling agent, 1-4 parts of lubricating agent, 2-20 parts of glass fiber, 0.01-0.2 part of allicin and 1-10 parts of wood fiber powder. According to the invention, glass fibers have the properties of good insulativity, strong heat resistance, good corrosion resistance and high mechanical strength, lignocellulose has small specific gravity, large specific surface area, excellent heat preservation, heat insulation, sound insulation, insulation, uniform thermal expansion, no cracking and excellent flexibility and dispersibility, a three-dimensional network structure is formed after mixing, and the glass fibers, the wood fibers and the filler are mixed, so thatthe strength of the master batch can be improved, cracking is not likely to happen, and performance is good.
