Thermal-insulation material for low-temperature pipelines
The invention relates to the technical field of thermal-insulation materials, more specifically a thermal-insulation material for low-temperature pipelines. The invention is characterized in that the thermal-insulation material for low-temperature pipelines is prepared from the following raw materials in parts by weight: 80-90 parts of straw, 20-25 parts of polyether glycol, 10-15 parts of modified coal slag, 1-2 parts of adhesive, 0.5-1 part of flame retardant, 1-2 parts of waterproofing agent and 2-3 parts of foaming agent. The straw is rationally utilized to save the energy source. The straw fiber has large pores, and thus, has favorable thermal-insulation effect. The added polyether glycol and modified coal slag can be attached into the pores of the straw fiber, thereby enhancing the thermal-insulation effect and hardness of the prepared thermal-insulation material.
