Abstract
The present invention relates to wallpaper and a method for manufacturing the same. The wallpaper may be manufactured at low energy and low costs regardless of an increase in oil price and does not produce greenhouse gases and hazardous substances in the course of manufacture, use or disposal, or during fire. In addition, the wallpaper can decompose readily in the natural environment, even when buried.
Claims19
A wallpaper comprising:
- a base sheet;
- and
- a resin layer formed on the base sheet and including a biodegradable resin, processing aids, and a lubricant,
- wherein the processing aids include a ter-polymer produced from a monomer mixture having 60 to 86 parts by weight of methyl methacrylate (MMA), 14 to 39.9 parts by weight of alkyl(meth)acrylate other than MMA, and 0.001 to 0.5 parts by weight of a functional monomer selected from the group consisting of aryl(meth)acrylate, a polyfunctional monomer, phenyl meth(acrylate), benzyl(meth)acrylate, 1,3-butylene glycol di(meth)acrylate, 1,4-butylene glycol di(meth)acrylate, divinyl benzene, ethylene glycol di(meth)acrylate and diethylene glycol di(meth)acrylate
- wherein the processing aids have a relative viscosity in the range of 4.0 cP to 12.0 cP, and
- wherein the processing aids have a weight average molecular weight of 500,000 to 8,000,000.

A wallpaper comprising:
- a base sheet;
- and
- a resin layer formed on the base sheet and including a biodegradable resin and processing aids, the biodegradable resin including 100 parts by weight of a first resin component containing poly(lactic acid) (PLA) to 10 to 60 parts by weight of a second resin component containing at least one selected from the group consisting of poly(butylene succinate) (PBS), poly(butylenesuccinate-co-adipate) (PBSA), and poly(butyleneadipate-co-terephthalate) (PBAT);
- wherein the processing aids include a ter-polymer produced from a monomer mixture having methyl methacrylate (MMA), alkyl(meth)acrylate other than MMA, and a functional monomer selected from a group consisting of aryl(meth)acrylate and a polyfunctional monomer, and
- wherein the processing aids have a weight average molecular weight of 500,000 to 8,000,000.
