摘要:
The present invention comprises material resin comprising polyamide or polyethylene-based resin; and polyacrylate copolymer obtained by absorption of acrylate monomer, polymerization initiator and functional monomer chosen from among acrylic acid, methacrylic acid, and a mixture of the acrylic acid and the methacrylic acid into the material resin and subsequent polymerization, providing polyacrylate-based polymer, where 128 to 955 parts by weight of the polyacrylate copolymer are used for every 100 parts by weight of the material resin.
摘要:
The present invention relates to a polyolefin-based resin composition for the calendering process which can be directly printed without applying an adhesive since the surface printability is improved.The present invention provides a polyolefin-based resin composition for the calendering process comprising: 3 to 95 weight percent, based on total weight of said polyolefin-based resin composition, of a high impact polyolefin resin; 1 to 50 weight percent, based on total weight of said polyolefin-based resin composition, of an acrylate functional polymer; 1 to 30 weight percent, based on total weight of said polyolefin-based resin composition, of a polyolefin-based thermoplastic elastomer; 1 to 50 weight percent, based on total weight of said polyolefin-based resin composition, of a mineral filler; and 0.1 to 5.0 weight percent, based on total weight of said polyolefin-based resin composition, of a lubricant.By the present invention, it is possible to remarkably improve the surface printability of the polyolefin-based sheet or film and thereby, to achieve direct printing without need of an adhesive. Also, since a production line for applying an adhesive is not needed, it is possible to reduce the production cost and to increase productivity. Further, the present invention can substitute for decoration sheets, printing papers, labels and the like which have been composed of PVC and thus, is environmentally friendly.
摘要:
Disclosed herein is a polyolefin-based thermoplastic polymer composition, in which an acrylate copolymer phase obtained by absorbing an alkyl acrylate monomer, an alkyl methacrylate monomer, a polar group-containing acrylate monomer and a polymerization initiator into a polyolefin matrix and then polymerizing the monomers is dispersed in a polyolefin phase. The thermoplastic polymer composition has excellent surface polarity leading to excellent paint adhesion.

The present invention relates to a polypropylene-based composite composition which is directly paintable without treatment of a primer comprised of chlorinated polyolefins. According to the present invention, the polypropylene-based composite composition comprises 30 to 70 weight percent, based on total weight of said polypropylene-based composite composition, of a polypropylene-based resin; 10 to 20 weight percent, based on total weight of said polypropylene-based composite composition, of a polyolefin based thermoplastic elastomer; 10 to 30 weight percent, based on total weight of said polypropylene-based composite composition, of a mineral filler; and 10 to 20 weight percent, based on total weight of said polypropylene-based composite composition, of an acrylate functional polymer additive.The composition does not need treatment of primer upon painting and thus has advantageous in terms of improvement of productivity resulting from reduction in production cost and production time and environment protection resulting from elimination of use of a primer comprised of chlorinated polyolefins.
