A NEW MASKING MEMBER
BACKGROUND OE THE INVENTION
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 o.f 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 deformatian during heating process of the surface
treatment. Further said masking member should be easily
burnt up after use:.
DESCRIPTION OF THE; PRIOR ART
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 ~~aid masking member is apt to break during
storage, tramsport:ation, 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 membesr.
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
-2- 1341 127
and still further, in the case of the combustion treatment
of the waste masking member, a large quantity of heat of
combustion is generated to damage the combustion furnace.
SUMMARw OF THE INVENTION
AccordingT_y, an abject of the present invention is
to improve the mechanical strength and the heat resistance
of the masking member.
Further object of the present invention is to save a .
thermoplastic resin as the material of the masking member.
Still furt=her object of the present invention is to
provide a mask~'_ng member which is easily burnt up after use.
Said objects of the present invention may be attained
by a molded marking member consisting of a thermoplastic
resin in which an inorganic filler is mixed. Said inorganic
filler may reinforce ~~aid thermoplastic resin of said
masking member to givE~ said masking member a good mechanical
strength, and i_urthe.r said inorganic filler gives said
masking member a good thermal conductivity and as the result
said masking member has a good heat resistance. Further,
2~ as said inorganic fi:ll.er reduces the ratio of said thermo-
plastic 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.
Since said inorganic f=iller is non-combustiable.

DETAILED DESCRIPTION
A masking member of the present invention consists of
a thermoplastic resin in which an inorganic filler is
mixed. did thermoplastic resin may be 'such as a polyethy-
lene, a polypropylene, an ethylene-propylene copolymer, an
ethylene-vinylacetate copolymer, a polyvinyl chloride,
a polyvinyl.idene chloride, a polyvinyl fluoride, a poly-
vinylidene :Fluoride, polystyrene, polyamide, polyester
and the like. Polyolefin such as a polyethylene, a poly-
propylene, ~snd 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 o:~cide, 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. In case that said inorganic filler
1341 127
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, moldabi:Lity and chemical resistance of said
thermoplastic resin may be deteriorated.
The masking member of the present invention may be
produced by vacuum forming, press molding, injection molding,
and the like. Vacuum forming is a most suitable molding
for mass-production of the masking member.
