Polymer-coated building insulation material and preparation method thereof

Abstract

The invention discloses a polymer-coated building insulation material. The polymer-coated building insulation material comprises the following raw materials in parts by weight: 1-2 parts of triglycidyl isocyanurate, 5-7 parts of diacetone alcohol, 2-3 parts of ammonium persulfate, 3-5 parts of phthalate, 110-120 parts of styrene, 10-13 parts of hollow glass microbeads, 4-5 parts of calcium aluminate, 10-14 parts of a polymer coating material, 0.4-1 part of 2-thiol benzimidazole and 3-5 parts of dimethylamine. Zeolite powder is coated with rosin, so that friction, impact and other damage, caused by the stone powder, to the glass microbeads are effectively prevented, and the hollow glass microbeads are further protected while the strength of a finished product is enhanced; the stone powder is coated with the rosin, so that the effect of enhancing the compatibility can be achieved, the agglomeration is effectively reduced, and a good promoting effect of improving the stability intensity of the finished product is achieved.

Problems solved by technology

As thermal insulation materials for buildings, low thermal conductivity and storage stability are the key to thermal insulation materials. However, traditional polystyrene foam materials have high thermal conductivity, and the added inorganic fillers have poor compatibility with polymers. , it is easy to reduce the storage stability of the finished product;

[0004] At the same time, the traditional hollow glass microspheres are easy to break as thermal insulation additives, thereby reducing the cost of mechanical properties and thermal insulation performance, while the foamed boards use a high amount of foaming agent and need to go through the foaming process, resulting in higher costs
