摘要:
An object of the present invention is to provide a material to be molded having a long storage life and good moldability and give a molded material having a good heat resistance. To attain said object, the present invention provides a material to be molded consisting of a porous material in which a thermoplastic resin is impregnated and further the present invention provides a manufacturing method of said material to be molded comprising impregnating a precondensation polymer of a thermosetting resin, heating and drying said porous material impregnating said thermosetting resin to condensate slightly to make it at B-stage.

An object of the present invention is to provide a dispersion of a hot-melt adhesive powder having a good stability and a product having an uniform quality using said dispersion. To attain the object, the present invention provides a dispersion of a hot-melt adhesive powder consisting of water and a hot-melt adhesive powder which is dispersed in said water. Preferable alkali-thickening type thickener may be an alkali-thickening type acrylic emulsion or an slightly cross-linked polyacrylic acid.

The object of the present invention is to provide a masking member which has good heat resistance and can be used repeatedly. To attain this object, the present invention provide a masking member made of a polymer alloy including one or more kinds of engineering plastics selected from a group consisting of methylpentene copolymer, polysulphone, polyethersulphone, polyphenylene, sulphide, polyphenylene ether, polyamideimide, polyetherimide, polyether-etherketone; and polyamide and/or polystyrene, and styrenic thermoplastic elastomer wherein said engineering plastics and said polyamide and/or polystyrene are mixed together in a weight ratio between 30 : 70 to 70 : 30, and 2 to 20 parts by weight of said styrenic thermoplastic elastomer is added in 100 parts by weight of said engineering plastics and polyamide and/or polystyrene. Said masking member has excellent moldability, a high level of mechanical strength and a good affinity with the coating film.
摘要:
The object of the present invention is to provide a masking member to protect a prescribed part of an article from coating, wherein said masking member has excellent heat resistance and moldability. As for the materials comprising said masking member (11,21,31,41,51), a polymer alloy, containing an engineering plastic, a polyamide, and a compatibilizer is used. In said polymer alloy, the weight ratio of said engineering plastic to said polyamide is set to be in the range of between 20:80 and 80:20, with said compatibilizer being added in an amount of between 0.01 and 50 parts by weight to 100 parts by weight of the sum of said engineering plastic and said polyamide
