Problems solved by technology

[0002] At present, pipelines in industrial and civil buildings have poor thermal insulation and sound insulation performance, especially in cold seasons and cold regions. Under zero temperature conditions or below minus 20°C, water, oil and other liquids or natural gas and other gases in the pipeline will not run normally. However, reducing the flow rate or bursting the pipe will seriously affect people's life and the normal operation of the energy industry; noise is a major source of pollution in the city, and the current pipeline is difficult to overcome the noise emitted by the flow of liquid and gas in the pipe, which is harmful to people's health

Abstract

This invention relates to a specialty elastomer web used for pipe warming, thermal insulating and noise insulating. It contains odor-free specialty elastomer, tackifying resin, white, light calcium carbonate, pottery clay, carbon black, age resister. The method includes (1) compound, (2) initial refine, (3)warm, (4)calender and compound, (5)press under low temperature,(6) appearance and dimension detect, (7)collect and coil. It can be used for enveloping and wrapping pipe in industry and civilian architectural, and petroleum or natural gas pipe, to prevent water freezing and pipe cracking under 0 deg.C, special -20deg.C or below. It can reduce noise to 10dB or below.
