Low-smoke thermal insulation material and preparation method thereof

The invention relates to the technical field of a thermal insulation material and a preparation method thereof, in particular to a low-smoke thermal insulation material and a preparation method thereof. The preparation method comprises the following steps of: step 1. accurately measuring materials; step 2. carrying out banbury mixing on the materials to obtain rubber No. 1; step 3. slicing the rubber No. 1 to obtain rubber slices No. 1; step 4. putting into an open mill, adding an accelerator; step 5. adding to an extruder for extrusion and molding; step 6. feeding a molding material into a drying oven for foaming to obtain rubber hoses; and step 7. introducing into a water tank for cooling; and step 8. shearing and packaging. The low-smoke thermal insulation material has the advantages ofno fiber, no dust, anti-condensation, soft surface and high anti-aging degree and is environmentally friendly and non-toxic; and when the low-smoke thermal insulation material is burned, smoke is reduced by 50%. 本发明涉及绝热材料及其制
