得られたものが提案されている。[Prior Art] Conventionally, carpet backing materials that have been required to have thermoformability, such as those used in automobiles, are disclosed in Japanese Patent Publication No. 47-46488 and Japanese Patent Publication No. 58-311.
70 and Japanese Patent Publication No. 59-14597, after applying various adhesives to the carpet for the purpose of fixing the carpet fibers, a method of laminating a polyethylene sheet or asphalt composition or the like to impart thermoformability,
JP-B-56-53282, JP-B-57-17112 and JP-A-60-591
As shown in 76, a method of mixing thermoplastic resin powder such as polyethylene and polystyrene into the adhesive emulsion, and adding various flame retardants, hydrated metal oxides, etc. to the adhesive emulsion to impart flame retardancy. What has been obtained by the method of doing is proposed.

なかった。However, the above-mentioned method, which is a conventional technique, requires two steps for lining the carpet, which is not a satisfactory method in terms of heat energy consumption and productivity. Since it is necessary and the structure of the adhesive itself is non-uniform, it is inferior in terms of thermoformability, mold holding property and fiber fixing property, and further improvement is desired. Further, the method (1) is also not preferable in terms of cost because the light resistance is decreased by the addition of the flame retardant, the heat moldability and the mold holding property are deteriorated, and these flame retardants are generally expensive.

下が図られる。The present inventors have completed the present invention as a result of extensive studies to solve the above problems. The object of the present invention is thermoformability,
An object of the present invention is to provide an improved adhesive for backing, which has excellent mold-retaining properties and fiber-fixing properties, and imparts flame retardancy without deteriorating these properties. Further, another object is to provide a so-called one-step processing backing adhesive that can be backed in one step without requiring two backing steps, thereby reducing the production cost of carpet. It can be reduced.
