Abstract
The invention relates to a body, particularly a molded body made of polystyrene, particularly polystyrene particle foam or polystyrene hard foam, wherein the polystyrene, particularly the polystyrene particle foam or the polystyrene hard foam, comprises petroleum coke, particularly petroleum coke particles.
Claims15
Body, in particular, a molded body made of polystyrene, in particular, made of polystyrene particle foam or polystyrene hard foam,
- characterized in that
- the polystyrene, in particular the polystyrene particle foam or the polystyrene hard foam, contains petroleum coke, in particular petroleum coke particles.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke consists of isotropic or anisotropic material.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke is produced as needle coke.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke particles or at least a part of the petroleum coke particles exhibit a platelet-like grain shape.
Body, as claimed any one of the preceding claims,
- characterized in that
- the petroleum coke particles exhibit an average particle size of 1 μm to 50 μm, preferably of 1 μm to 10 μm.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke particles were ground in delamination mills.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke particles were ground in ball mills.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke particles were ground in air jet mills.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke particles exhibit an aspect ratio of 1 to 500, preferably 5 to 50.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the petroleum coke content is in a range between 0.5% by weight and 10% by weight, based on the finished body.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the body has a density of less than 40 kg/m3.
Body, as claimed in any one of the preceding claims,
- characterized in that
- the body has a coefficient of thermal conductivity ranging from 20 mW/(m·K) to 40 mW/(m·K), in particular from 25 mW/(m·K) to 30 mW/(m·K),
Body, as claimed in any one of the preceding claims,
- characterized in that
- the thermal conductivity of the body comprising petroleum coke is reduced by 25% to 35%, compared to a corresponding body without petroleum coke.
