2. Description of the Related Art Conventionally, flooring made of vinyl chloride resin has been frequently used for flooring of buildings and condominiums. This causes a large amount of harmful effects on the human body and hinders evacuation and fire fighting. In addition, since a large amount of a plasticizer or a stabilizer is contained, there is a problem in that contamination by bleeding of the plasticizer is observed and the odor is strong.

２０20 g / 10 min.

The melt index (MI) is 0.5 g /
If the amount is less than 10 minutes, the melt moldability decreases when a large amount of a filler is blended. If the amount exceeds 50 g / 10 minutes, the melt tension decreases, which is not preferable.

The ethylene-vinyl acetate copolymer (B) used in the present invention has a vinyl acetate content of 66 to 90% by weight (preferably 66 to 85% by weight) and a melt index (MI) of 0.05 to 0.05%. 150 g / 10 minutes (190
° C, 2160 g load), the n-hexane soluble content is less than 10% by weight (preferably less than 5% by weight), and the weight average molecular weight is 150,000 or more (preferably 200,000 or more), or the insoluble content in benzene is It must be at least 3% by weight.

When the vinyl acetate content is less than 66% by weight, the adhesiveness is lowered, and the melt tension at the time of blending with other components is lowered. When it exceeds 90% by weight, the heat resistance is lowered. If the melt index (MI) is less than 0.05 g / 10 minutes, the fluidity at the time of melting is reduced, and the moldability is deteriorated. If the melt index (MI) exceeds 150 g / 10 minutes, stickiness occurs when blended with other components. Tension decreases.

If the n-hexane-soluble matter or the weight-average molecular weight or the benzene-insoluble matter is out of the above-mentioned range, contamination of the molding machine occurs at the time of mixing or molding, resulting in a decrease in releasability and a reduction in gloss of the molded product. Will decrease.

The method for producing the ethylene-vinyl acetate copolymer (B) is not particularly limited. For example, vinyl acetate and ethylene or a small amount of an ethylenically unsaturated monomer copolymerizable therewith may be used. After obtaining an aqueous dispersion or solution by suspension polymerization, emulsion polymerization, solution polymerization method, drying, salting out and any other method such as ethylene-
A vinyl acetate copolymer (B) is obtained.
