Abstract

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.

Description

technical field [0001] A pipe reinforcement masterbatch and a preparation method thereof, the invention belongs to the technical field of plastic building materials, in particular to the technical field of pipe masterbatch. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials. The quality of the pipe directly determines the quality of the pipe fittings. With the development of technology, plastic pipes have gradually replaced traditional pipes such as cast iron pipes and galvanized steel pipes and become the mainstream used pipes. Compared with traditional pipes, plastic pipes have significant advantages such as light weight, corrosion resistance, small water flow resistance, energy saving, easy and fast installation, and low cost, and are favored by the pipeline engineering industry. [0003] Calcium carbonate can play a skeleton role in plastic products, which has a great effect on the dimensio...
