Abstract

The invention discloses a building heat-insulating foam material. The foam material is prepared from, by weight, 5-7 parts of potassium titanate whiskers, 130-150 parts of styrene, 5-7 parts of an initiator, 6-8 parts of zinc diricinoleate, 20-30 parts of an organic filler emulsion, 10-12 parts of a foaming agent, 2-4 parts of rosin powder, 1-2 parts of melamine and 0.8-1 part of polyethylene glycol fatty acid ester. The styrene used as a monomer is mixed with an alcohol ester solution, the obtained solution is polymerized under the action of the initiator, and the obtained polymer is mixed with the rosin powder and the foaming agent to realize foaming, so the foaming effect is effectively improved, thereby the foam material has low thermal conductivity, good heat insulation property and excellent comprehensive performances.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a building foam insulation material and a preparation method thereof. Background technique [0002] Expanded polystyrene resin has a wide range of uses.
