Abstract

The invention discloses an insulation board which is prepared from the following raw materials in parts by weight: 25 to 33 parts of slag powder, 20 to 28 parts of sawdust, 18 to 26 parts of straw fiber, 10 to 18 parts of adhesive, 15 to 23 parts of polystyrene resin, 22 to 30 parts of foaming agent, 8 to 16 parts of antioxidant, 5 to 13 parts of stabilizer, 1 to 5 parts of fire retardant and 5 to 13 parts of catalyst. Further, the insulation board comprises the following raw materials in parts by weight: 25 parts of slag powder, 20 parts of sawdust, 18 parts of straw fibers, 10 parts of an adhesive, 15 parts of polystyrene resin, 22 parts of a foaming agent, 8 parts of an antioxidant, 5 parts of a stabilizer, 1 part of a fireproof agent and 5 parts of a catalyst. The prepared heat insulation board is good in heat transfer coefficient, fireproof performance, specific gravity, compressive strength and breaking strength and has low heat conductivity so that better heat insulation performance is guaranteed, and the insulation board has excellent toughness and rigidity.

Description

Technical field[0001]The present invention relates to the field of preparation process of the insulation board, and more particularly to an insulation plate and a method of fabricating it.Background technique[0002]The thermal insulation board is easy to understand is a plate for the building. The insulation plate is a polystyrene resin as a raw material plus other raw materials and polymers, and the hard foam plate produced by heat mixing with the catalyst by heating, then extruding the pressure-out molding, has moisture-proof, waterproof performance, Reduce the thickness of the outer enclosure structure of the building, thereby increasing the indoor use area.[0003]At present, there is an epidemic building in my country, an external thermal temperature material EPS (molded polybenzene sheet) XPS (extruded polybenades) and PU (polyurethane), etc., due to fire, insulation, etc., it is not well to meet the national architectural norm Requirements, but the demand in the building materia...
