Definitions
- masking members consisting of a polystyrene foam sheet (USSN 061,700, USSN 100,524, USSN 101,689).
- Said polystyrene foam sheet what is called polystyrene paper, may be very suitable for the material of a masking member since said polystyrene foam sheet is inexpensive and easily molded by such as vacuum forming and the like.
- Said masking member consisting of said polystyrene foam sheet may be removed by employing a hook or by heating. Since said polystyrene foam is one of the most brittle of plastic foams, a hook may be easily stuck into said masking member consisting of said polystyrene foam sheet.
- said polystyrene foam sheet of said masking member has a closed cell
- air and blowing gas in said closed cell may expand and simultaneously the masking member may also expand, and then said expanding air and blowing gas will break said closed cell and said air and blowing gas will escape from said closed cell and as the result, the masking member may shrink.
- said high-impact polystyrene is dissolved in an organic solvent, such as toluene, ethyl acetate, and the like but said high-impact polystyrene has better resistance against an organic solvent than said polystyrene foam and said high-impact polystyrene film may protect completely said polystyrene foam sheet from the poorer solvents of polystyrene, such as methanol, ethanol, and the like, and further, said high-impact polystyrene film may protect said polystyrene foam sheet from the strong solvents of polystyrene, such as toluene, ethyl acetate and the like in a short exposure of said strong solvents.
- an organic solvent such as toluene, ethyl acetate, and the like
- said high-impact polystyrene film may protect completely said polystyrene foam sheet from the poorer solvents of polystyrene, such as methanol,
- thermoplastic film may be laminated on one or both side(s) of said polystyrene foam sheet when said polystyrene foam sheet is produced by extrusion foaming, or after said polystyrene foam sheet is produced by extrusion foaming, such as when said polystyrene foam sheet is molded by vacuum forming.
- said thermoplastic film is attached to said polystyrene foam sheet by heating or by using an adhesive.
- the expansion ratio of said polystyrene foam sheet may be commonly from 2 to 50 times and desirably from 7 to 20 times and the thickness of said sheet may be 0.5 to 7 mm, and the thickness of said thermoplastic film may be 0.001 to 1 mm.
- the masking member of the present invention may be produced by vacuum forming, pressing, blow-molding, cutting, and the like from said laminated sheet and if desirable, an adhesive layer may be formed partially or wholly on the surface of said masking member. Said adhesive layer may be formed by coating an adhesive on said surface of said masking member and drying said coated adhesive. It is desirable to use an emulsion type adhesive since said emulsion type adhesive does not make said polystyrene foam sheet of said masking member swell or dissolve and it is desirable to add a water soluble polymer in said emulsion type adhesive to increase cohesion of said adhesive (USSN 001,822). In the case where cohesion of said adhesive is increased by adding said water soluble polymer, said water soluble polymer may prevent transfer of said adhesive to the part of the article to which the masking member has been attached when said masking member is removed from said part.
- Said masking member of the present invention may be used in the coating process of the automobile industry such as the coating of a car body, the coating of bumpers, the corrosion, sound, and vibration-proof treatment of the underside of a car body by using a viscoelastic material such as polyvinylchloride sol, polyurethane, tar-polyurethane, and the like, and also said masking member of the present invention may be used in the coating process of the house hold electric furnishings industry, such as the coating of electric refrigerators, televisions, and the like.
