초록 ▼

A plastic foam material composed of a blended resin composition which includes at least two thermoplastic resins and a silane-modified based resin. The blended resin composition consists essentially of 100 parts by weight of at least two thermoplastic resins, from about 1 to about 50 parts by weight of a silane-modified, cross-linked, thermoplastic resin; from about 0.001 to about 2.5 parts by weight of a cross-linking catalyst for use in a silane compound and from about 1 to about 20 parts by weight of a foaming agent. According to one embodiment of the present invention, the thermoplastic resins include at least two substantially incompatible and substantially uncross-linked thermoplastic resins, while in another embodiment the two thermoplastic resins need not be substantially incompatible. The blended resin composition may further include reinforcers such as glass fibers and filler. The thermodecomposition foaming agent decomposes at sufficiently high temperatures to yield a plastic foam material. The resultant plastic foam material, in turn, exhibits superior resilience, improved compression strength and superior heat-insulating properties. A method to produce the plastic foam material from foamable tubes and foamable pieces is also disclosed.

대표청구항 ▼

A method for preparing a plastic foam material comprising thermoplastic resins, comprising the steps of: preparing about 100 parts by weight of at least two substantially incompatible resins selected from the group consisting of a polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, and polystyrene to form a first mixture; adding from about 1 to about 50 parts by weight of a silane-modified thermoplastic resin of the same polymer type as at least one of said two substantially incompatible resins to said first mixture; adding from about 0.001 to about 2.5 parts by weight of a cross-linking catalyst effective to cross-link said silane-modified thermoplastic resin and; adding from about 1 to about 20 parts by weight of a foaming agent to said first mixture to form a blended resin composition; extruding said blended resin composition to form an object; exposing said object to a first cross-linking source to form a cross-linked object wherein said cross-linked object includes only cross-linked silane-modified thermoplastic resin; and exposing said object to a foaming heat source to form said plastic foam material.
