Abstract

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%.

Description

technical field [0001] The invention relates to the technical field of heat insulation materials and preparation methods thereof, in particular to a low-smoke heat insulation material and a preparation method thereof. Background technique [0002] Thermal insulation material refers to the material that can block the transfer of heat flow, also known as thermal insulation material. Traditional thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., new thermal insulation materials, such as airgel felt, vacuum panels, etc. They are used in building envelopes or thermal equipment, materials or material composites that resist heat flow transfer, including thermal insulation materials and cold insulation materials. On the one hand, thermal insulation materials meet the thermal environment of building space or thermal equipment, and on the other hand, they also save energy. [0003] At present, the thermal insulation materials on the market will p...
