The content of glass wool is preferably 1 weight % to 20 weight %, more preferably 1 weight % to 10 weight %, it is outstanding preferably
For 2 weight % to 5 weight %.If the content of glass wool is less than 1 weight %, it is difficult to form gauffer apperance.On the other hand, if glass
The content of glass suede is more than 20 weight %, then the strength reduction of formed products is not so good enough.Furthermore the present invention in it is so-called " glass wool
Content " refers to weight/(weight of thermoplastic resin and/or thermoplastic elastomer (TPE)) of glass wool.
In addition, in melting step well known ultraviolet radiation absorption can also be deployed in the range of not undermining the object of the invention
Agent, stabilizer, antioxidant, plasticiser, colorant, toner, fire retardant, antistatic agent, fluorescent bleaches, delustering agent, punching
The additives such as hit intensity modifying agent.
About extrusion step, as long as being kneaded object from extrusion for the melting made in step can will be melted by extrusion molding method
The outlet of mold squeezes out and the method that manufactures formed products, then there is no particular restriction.Such as by being squeezed out from cricoid outlet
Melting is kneaded object, extrudable slightly thick tubular formed products.The manufacturing method has the socket etc. of filling cosmetics or food etc.
With.
In addition, melting can also be kneaded object extrusion by plavini from cricoid outlet manufactures formed products.By swollen
Swollen method and one end can also be cut before batching and flat film be made by the formed products that manufacture, may be made as cylindrical body.If utilizing
Roller with gauffer squeezes cylindrical body, then constitutes the film of cylindrical body then, therefore can not previously be manufactured by plavini with bumps
Cylindrical body.However, by the way that glass wool to be added in resin etc., not implementing gauffer in the present invention to formed products and processing and shape
At gauffer apperance, so it is particularly useful for the manufacture of the cylindrical body using plavini.In by cylindrical body manufacture refuse bag etc.
When situation, because being formed with gauffer apperance in surface, so bag can break a seal easily.
In addition, in extrusion step, it is possible to use following method (T-die method): in the front end of extruder, setting is claimed
For the mold with linear outlet of T-die, squeezes out flat material and be continuously manufactured by formed products.T-die method
In, film is cooled down by chill roll (chillroll) through mirror surface treatment, during until final batch into
The width for cutting etc. and adjusting film of row end.Previously, gauffer mould was formed and a part of roller to be set as to the roller with gauffer
Sample.However, gauffer apperance is formed in the surface of film and the addition glass wool in resin etc. in the present invention, so can not also
Use the roller with gauffer.Furthermore when being intended to form the situation of deeper gauffer (bumps), the roller with gauffer can also be further utilized
The film for being formed with gauffer apperance is squeezed.
Formed products can be that single layer is also multilayer.When the situation of multilayer is made, as long as carrying out co-extrusion when extrusion step
Out, the coextrusion is the method that a variety of raw material are disposably squeezed out and are overlapped.Such as plavini situation when, can arrange
It lifts: the die head foreset bed method for contacting each molten resin in the feed block before mold；It is contacted in the path of mould inside
Lamination method in die head；Lamination method outside the die head for being discharged and contacting from multiple outlets of concentric circles.
In addition, can be enumerated when the situation of T-die method: the setting feed block before the wink that will enter die head, via undertaking
Seat connects single manifold method, the branch manifold method of multiple extruders to feed block.Single manifold method be on one side in feed block in make resin etc.
Contact is on one side formed film by die head.The number of plies can be set by replacing stacker, therefore can relatively simply obtain multilayer
Film.Branch manifold method is to make the resin supplied from multiple extruders in will be to using the internal T-die with multiple manifolds
Up to outlet preceding contact and carry out lamination.The big material of the physical property such as differences in viscosity difference can be coextruded, and be easily adjusted each
The thickness of layer.
Furthermore the coextrusion of the plavini and T-die method is the typical example of the manufacturing method of lamination formed products, but only
It finally can get the formed products of lamination, then can also be other manufacturing methods such as laminating method.If in addition, usually passing through extrusion molding
Legal system makes formed products, then the physical property of formed products is different from vertical direction in squeezing out direction in most cases.However, implementing as be described hereinafter
Shown in example, for formed products of the invention by addition glass wool, the physical property difference for squeezing out direction and vertical direction can be reduced by also generating
Effect.
When formed products are the situation of the multilayer product through lamination, preferably at least one layer of the outer layer of multilayer product is that will set
The melting of rouge etc. and glass wool is kneaded layer made of object squeezes out.Layer by addition glass wool in outside forms gauffer apperance,
So assigning feeling of high class, and the contiguity of formed products can be prevented.Furthermore when the situation of multilayer product, it can also be formed resin etc.
And the melting of glass wool is kneaded interior layer of the layer as multilayer product made of object squeezes out.When being formed as the situation of interior layer, lead to
It crosses gauffer apperance and increases specific surface area, therefore improved with the followability of upper and lower layer.
As long as using well known method the melting squeezed out to be kneaded object cooling for cooling step, as long as such as passing through sky
Air cooling etc. carries out cooling.
Formed products are preferably shaped to film, sheet material or cylindrical body.Furthermore in the present invention, according to JIS
(JapaneseIndustrialStandards；Japanese Industrial Standards), " film " refer to " plastic cement of the thickness less than 250 μm it is membranaceous
Object ", " sheet material " refer to " laminal object of 250 μm of thickness or more of plastic cement ".The thickness of formed products (film, sheet material, cylindrical body) is only
It to be the diameter range that is thicker, and being formed by extrusion molding method of relatively added glass wool, then there is no particular restriction, excellent
It is selected as about 3 μm to 300 μm or so, even more preferably about 5 μm to 275 μm or so, even more preferably about 8 μm to 250 μm or so.If about
3 μm hereinafter, the then excessively thin and easy breakage of formed products.In addition, if about 300 μm or more, then form gauffer apperance and film be difficult to it is close
The advantage that connects and can reduce the extrusion direction of formed products and the physical property difference of vertical direction tails off.
Furthermore in the present invention, so-called " formed products " are unrelated with single layer, multilayer, refer to by extrusion molding method that melting is mixed
Practice object to squeeze out and cooled down resulting article.Therefore, so-called formed products with a thickness of about 3 μm to 300 μm, refer to and pass through extrusion
The thickness of sheet material manufactured by forming process, film or cylindrical body itself, rather than mean for these articles to be attached at system made of plate etc.
The thickness of product.
Furthermore present inventor has been carried out the patent Shen for being compounded to form material that glass wool is filled in thermoplastic resin
Please (referring to No. 5220934 bulletins of Japanese Patent No.).However, that records in No. 5220934 bulletins of Japanese Patent No. is compounded to form
Material is made to the invention of the loading of the fiber length and increase glass wool that extend the glass wool filled into thermoplastic resin
The particle and injection molding product of ejection formation are only described for the form of article.On the other hand, formed products of the invention are certainly
The outlet of extrusion die is squeezed out and is formed.When carrying out the situation of ejection formation, it is compounded to form material because projecting in mold,
Therefore gauffer apperance is not formed in formed products.Therefore, formation of the invention has the manufacturing method and formation of the formed products of gauffer apperance
There are the formed products of gauffer apperance different from the manufacturing method and injection molding product recorded in Japanese Patent No. 5220934.
As the purposes of formed products of the invention, can enumerate: waterproof sheet, roof ground, is repaired concrete forming waterproof material
