CEMENT-COATED EXPANDED-RESIN BLOCK

PROBLEM TO BE SOLVED: To provide a method for changing an expandable resin material used for a flame-retardant material which has flame-retardancy, is lightweight, the cost of which is reduced and which abounds in soundproofness and heat insulating properties, into the flame-retardant material. SOLUTION: Cement paste 4 in which cement 2 of 100 pts. wt. and water 3 of 30 to 100 pts. wt. are mixed, and an emulsion 5 in which water of 5 to 200 pts. wt. is emulsified and liquefied to a polymer resin of 5 to 50 pts. wt. are mixed, and polymer cement 6 is manufactured. A expanded polystyrene material as a block shape for construction is dipped into the polymer cement 6 and the polymer cement 6 is attached to the surface of a expanded polystyrene resin article 7 and pulled up and cured, and a polymer-cement solidified layer 11b is formed on the surface of the article 7 and a floor block material 11 as the flame-retardant material is manufactured. A tile 12 is stuck on the top face of the floor block material 11 with mortar and used for a floor structure. COPYRIGHT: (C)2004,JPO
