Abstract

The invention provides a preparation method of a high-temperature-resistant anti-aging polyethylene foamed tubular material, wherein the preparation method comprises the following steps: a, preparation of an A material: carrying out mixed melting of 170-215 parts by weight of polyethylene with the density of 0.905-0.918 g / cm<3> and 2-10 parts by weight of a modifier at the temperature of 150-180 DEG C to obtain the A material; b, preparation of a B material: carrying out mixed melting of 5-10 parts by weight of polyethylene with the density of 0.920-0.935 g / cm<3> and 0.3-1 parts by weight of an antioxidant at the temperature of 150-180 DEG C to obtain the B material; and c, mixed foaming: mixing the A material prepared in the step a and the B material prepared in the step b, adding 10-15 parts of a foaming agent, foaming, and thus obtaining a finished product. The invention also provides the high-temperature-resistant anti-aging polyethylene foamed tubular material comprising the following components in parts by weight: 180-220 parts of polyethylene, 2-10 parts of the modifier, 0.3-1 part of the antioxidant, and 10-15 parts of the foaming agent. The foamed tubular material improves the shrinkage resistance, high temperature resistance and anti-aging performance, prolongs the service life, is environmentally friendly, has the cost lower than rubber and plastics, and can basically replace the rubber and plastics for use in household electrical appliance industry.

Description

technical field [0001] The invention relates to a polyethylene material and a preparation method thereof, in particular to a high-temperature-resistant and aging-resistant polyethylene foam pipe and a preparation method thereof. Background technique [0002] At present, with the rapid development of my country's housing industry and the continuous advancement of urban construction and western development, the investment in urban infrastructure construction continues to increase, bringing huge market demand for plastic pipes. Statistics show that by the end of 2010, at least 80% of the country's building water supply and hot water supply fields use plastic pipes, and the demand for plastic pipes has reached 80,000-100,000 tons per year. That is, plastic pipes have been well developed in the field of cold and hot water transportation. However, people have found in the process of using plastic pipes that ordinary plastic pipes are made of ten materials, which causes some short...
