专利汇可以提供Nonflammable plastic foam molded product, manufacture thereof and concrete placement form专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a nonflemmable foam molded having incombustible protective layer by a structure wherein the matter prepared by kneading cement, to which silica sand is added to cement when necessary, aqueous solution of salts, which consists mainly of calcium salt and auxiliary of iron salt or the like, and latex for cement when required, one another is applied on the surface of a plastic foam molded product and cured. CONSTITUTION:A nonflemmable plastic foamed molded product, which has surface hardness and is strong in compression and bending, is manufacturing by applying the matter prepared by kneading cement, to which silica sand is added when required, aqueous solution of salts, which consists mainly of calcium salt and auxiliary of iron salt, potassium salt or ammonium salt, and latex for cement when necessary, one another and cured. For example, a flexible cured layer 2 made of the matter prepared by kneading in the thickness of 1-2mm is formed on the surface of a plate-shaped molded product 1 made of polystyrene foam having the expansion ratio of 30-60times in the thickness of about 30mm. The obtained product can satisfactorily available as a concrete placement form 3 and, further strongly joined to a concrete block, which is placed and hardened.,下面是Nonflammable plastic foam molded product, manufacture thereof and concrete placement form专利的具体信息内容。
