Embodiment 1
[0039] This embodiment discloses a sugar resin insulation material, which includes the following ingredients in parts by mass:
[0040] 100 parts of sugar resin, 2.5 parts of foam stabilizer (AK-8805 silicone oil, produced by Nanjing Meisid New Material Co., Ltd.), 1.5 parts of catalyst potassium oleate (purchased from Shanghai Deyin Chemical Co., Ltd.), solidflame retardant trioxide 35 parts of antimony, 15 parts of TCEP liquid flame retardant (manufactured by Qingdao Lianmei Chemical Co., Ltd.), 4 parts of curing agent ammoniumsulfate, and 3 parts of purified water.
[0041] The present embodiment further provides the preparation method of this sugar resin insulation material:
[0042] 1) Add the sugar resin into the stirring tank and the temperature rises to 60 degrees, then add the foam stabilizer and catalyst into the stirring tank at the same time and stir for 15 minutes,
[0043] 2) Then add purified water, solid flame retardant and liquid flame retardant into the mi...
Embodiment 2
[0049] This embodiment discloses a sugar resin insulation material, which includes the following ingredients in parts by mass:
[0050]100 parts of sugar resin, 5 parts of crosslinking agent polyether 403, 2.5 parts of foam stabilizer (AK-8805 silicone oil), 1.5 parts of catalyst potassium oleate (purchased from Shanghai Deyin Chemical Co., Ltd.), solid flame retardant 20 parts of antimony, 15 parts of TCEP liquid flame retardant (purchased from Qingdao Lianmei Chemical Co., Ltd.), 4 parts of curing agent ammoniumsulfate, and 3 parts of purified water.
[0051] The preparation method is the same as in Example 1, wherein the crosslinking agent is added together with the sugar resin in step 1).
[0052] The sugar resin insulation material obtained in this embodiment was tested, and the product density was 37 kg / m3, the compressive strength was 70 kPa, the thermal conductivity was 0.037 W / m·k, the dimensional stability was 5%, and the water absorption rate was 8%. The fire perf...
Embodiment 3
[0054] The same formula as Example 2, just do not add purified water. The preparation method is the same as in Example 2, and the thermal conductivity of the product is 0.027W / m·k. Therefore, it is judged that water is the main factor affecting the thermal conductivity. Subsequent tests did not add water.

Abstract
The invention proposes a sugar resin thermal insulation material and its preparation and recycling. The sugar resin insulation material includes the following components by mass: 80-100 parts of sugar resin, 0-8 parts of crosslinking agent, 2-3 parts of foam stabilizer, 1-2 parts of catalyst, 10-50 parts of flame retardant, 10-20 parts of liquid flame retardant, 0-3 parts of chain extender, 0-6 parts of foaming agent, 4-15 parts of curing agent, and 0-3 parts of water. The sugar resin insulation material proposed by the present invention uses sugar resin as the main raw material; sugar resin is a formaldehyde-free, degradable, renewable carbohydrate, and is a thermosetting resin; the foam product produced by the invention has stable performance and low VOC, eco-friendly features.
Description
technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-efficiency thermal insulation material and its preparation and application. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. As the main functional material for energy saving and consumption reduction, thermal insulation materials are widely used in building exterior walls, vehicle decoration, refrigeration facilities, boat interiors and other fields. Thermal insulation materials include inorganic thermal insulation materials and organic synthetic thermal insulation materials. The non-polar ones mainly include glass wool, rock wool, expanded perlite, foamed cement, etc. When used in industrial facilities or vehicle and ship interior decoration, there are defects such as difficult molding and complicated processing. ;Organic synthetic materials include polystyrene board, polyureth...
