Embodiment 1
[0013] A thermal insulation material comprising 80% of polyurethane, 15% of perlite, and 5% of additives, said additives comprising 3% of hexabromocyclododecane, 1% of polyether polyol, 1% of cyclopentane %. This program can save 12% cost.
[0014] The preparation method of described insulation material is:
[0015] Polyurethane is produced by foaming the black and white material liquid. After mixing the additives and the black and white material liquid together, the perlite and the black and white material are injected for cross-linking in 70s to 90s, and then the mixture enters the mold together.
Embodiment 2
[0017] A thermal insulation material comprising 50% of polyurethane, 40% of perlite, and 10% of additives, said additives comprising 6% of hexabromocyclododecane, 2% of polyether polyol, 2% of cyclopentane %. This program can save about 25% of the cost.
[0018] The preparation method is the same as in Example 1.
Embodiment 3
[0020] A thermal insulation material comprising 30% of polyurethane, 50% of perlite, and 20% of additives, said additives comprising 15% of hexabromocyclododecane, 2% of polyether polyol, 3% of cyclopentane %. This program can save 40% of the cost.
[0021] The preparation method is the same as in Example 1.
[0025] The same cubic foamed finished product, such as adding 50% perlite, saves 40% of the cost compared with polyurethane alone, such as adding 15% perlite, and saves 12% of the cost compared with polyurethane alone.

Abstract
The invention discloses a thermal insulation material, which comprises 10-50 parts by volume of pearlite 30-80 parts by foamed volume of polyurethane, and also comprises an additive accounting for 1-20% of the total weight of the thermal insulation material, the additive comprises, by the total weight of the thermal insulation material, 1-15% of hexabromocyclododecane, 1-5% of polyether polyols and 1-5% of cyclopentane. The invention also provides a preparation method of the thermal insulation material. The perlite is light in mass and large in volume, can replace a large portion of foamed polyurethane volume, while the polyurethane is added into the system for adhesivepolymerization, and by use of the technical scheme of the thermal insulation material, the polyurethane foaming cost is saved by 30-50%, compared with conventional polyurethane foaming cost.
Description
technical field [0001] The invention relates to a new type of thermal insulation material, in particular to a foamed thermal insulation material, and also relates to a preparation method of the thermal insulation material. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.2. Using good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. [0003] Among them, organic insulation materials mainly include polyurethane foam, polystyrene board, phenolic foam, etc. Simple use of polyurethane foam, the cost is higher. Contents of the invention [0004] The object of the present invention is to provide an insulating material with low weight and low cost. [0005] The present invention is achieved like this: [0006] A thermal insulation material, comprising 10-50 parts by volume of perlite and 30-80 parts by volume of polyureth...
