Definitions
- the present invention relates to a new masking member. More particularly, the present invention relates to a new masking member consisting of a thermoplastic resin in which an inorganic filler is mixed.
- the masking member is used to protect a part of an article from a surface treatment such as coating, plating, phosphotizing and the like, and the masking member may be removed from said part after said surface treatment.
- Said masking member should have a good mechanical strength and heat resistance to avoid break of said masking member during storage, transportaion and the like and deformation during heating process of the surface treatment. Further said masking member should be easily burnt up after use.
- a masking member having a vessel form and consisting of a thermoplastic resin film has been provided to protect a hole of an article from a surface treatment (Japanese Patent Publication No. 248,249/1985). Said masking member is easily mass-produced by such as vacuum forming, and the like since said masking member consists of said thermoplastic resin film which has a good moldability.
- the mechanical strength and the heat resistance of said masking member is not enough and said masking member is apt to break during storage, transportation, and the like and apt to deform during heating process of said surface treatment since the residual stress originating from the molding remains in said masking member.
- thermoplastic resin as the material of said masking member is wasted since said masking member fully consists of said thermoplastic resin and still further, in the case of combustion treatment of the waste masking member, a large quantity of heat of combustion is generated to damage the combustion furnace.
- EP-A-0243498 discloses a paint comprising carbon black and a resinous component, which paint may be painted onto a surface and then dried to form a strippable masking film. Such a paint is time consuming to both apply and dry and requires special equipment for this. Furthermore, the paint is not suited for application to three dimensional surfaces.
- a molded masking member consisting of a thermoplastic resin in which an inorganic filler is mixed.
- Said inorganic filler may reinforce said thermoplastic resin of said masking member to give said masking member a good mechanical strength, and further said inorganic filler gives said masking member a good thermal conductivity and as the result said masking member has a good heat resistance. Further, as said inorganic filler reduces the ratio of said thermoplastic resin in said masking member, said thermoplastic resin as the material of said masking member can be saved and heat of combustion can be also reduced generated from the combustion treatment of the waste masking member.
- a masking member of the present invention consists of a thermoplastic resin in which an inorganic filler is mixed.
- Said thermoplastic resin may be such as a polyethylene, a polypropylene, an ethylene-propylene copolymer, an ethylene-vinylacetate copolymer, a polyvinyl chloride, a polyvinylidene chloride, a polyvinyl fluoride, a polyvinylidene fluoride, polystyrene, polyamide, polyester and the like.
- Polyolefin such as a polyethylene, a polypropylene, and the like is a desirable thermoplastic resin as a material of the masking member of the present invention since said polyolefin has a good solvent resistance.
- Said inorganic filler may be such as a calcium carbonate, a talc, a bentonite, a titan white, a carbon black, a rediron oxide, a glass powder, a celamic powder, a blast furnace slag, a flyash, and the like.
- a calcium carbonate is a desirable inorganic filler since said calcium carbonate has a good compatibility with said thermoplastic resin. Generally, 5 to 80% by weight, more desirably 10 to 60% by weight of said inorganic filler is mixed in said thermoplastic resin.
- thermoplastic resin In case that said inorganic filler is mixed to said thermoplastic resin less than 5% by weight, heat resistance and mechanical strength of said thermoplastic resin may be not enough, while in case that said inorganic filler is mixed to said thermoplastic resin more than 80% by weight, moldability and chemical resistance of said thermoplastic resin may be deteriorated.

Said masking member should have a good mechanical strength and heat resistance to avoid break of said masking member during storage, transportaion and the like and deformation during heating process of the surface treatment. Further said masking member should be easily burnt up after use.
- Hitherto, a masking member having a vessel form and consisting of a thermoplastic resin film has been provided to protect a hole of an article from a surface treatment (Japanese Patent Publication No. 248,249/1985). Said masking member is easily mass-produced by such as vacuum forming, and the like since said masking member consists of said thermoplastic resin film which has a good moldability. On the other hand, the mechanical strength and the heat resistance of said masking member is not enough and said masking member is apt to break during storage, transportation, and the like and apt to deform during heating process of said surface treatment since the residual stress originating from the molding remains in said masking member.
- Further a large quantity of said thermoplastic resin as the material of said masking member is wasted since said masking member fully consists of said thermoplastic resin and still further, in the case of combustion treatment of the waste masking member, a large quantity of heat of combustion is generated to damage the combustion furnace.
- EP-A-0243498 discloses a paint comprising carbon black and a resinous component, which paint may be painted onto a surface and then dried to form a strippable masking film. Such a paint is time consuming to both apply and dry and requires special equipment for this. Furthermore, the paint is not suited for application to three dimensional surfaces.
- According to the present invention there is provided a molded masking member consisting of a thermoplastic resin in which an inorganic filler is mixed.
- Said inorganic filler may reinforce said thermoplastic resin of said masking member to give said masking member a good mechanical strength, and further said inorganic filler gives said masking member a good thermal conductivity and as the result said masking member has a good heat resistance. Further, as said inorganic filler reduces the ratio of said thermoplastic resin in said masking member, said thermoplastic resin as the material of said masking member can be saved and heat of combustion can be also reduced generated from the combustion treatment of the waste masking member.
