Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Generally, ABS resin is a thermoplastic resin that is well-balanced in terms of good impact resistance, rigidity, moldability, good appearance, and ease of secondary processing. is there. Current demand areas include vehicle interior and exterior applications, home appliances such as refrigerators, vacuum cleaners, and air conditioners, AV applications such as video cameras, OA equipment such as personal computers, facsimile machines, printers, equipment such as telephones, housing equipment, and TVs.
It is used in a very wide range of fields such as leisure and miscellaneous goods such as game machines, pachinko and toys. Also generally A
The BS resin product is manufactured by extrusion molding and injection molding because the releasability from the roll surface is poor in calendering. The present invention relates to an ABS resin composition for calendering, and it is an object of the present invention to provide an ABS resin composition having excellent calendar lubrication and having significantly improved coloring due to thermal decomposition.

[0002]

2. Description of the Related Art Conventionally, as a method of manufacturing a sheet of ABS resin, extrusion molding has been mainly used because of its easy processing. However, as a method for producing a sheet-like product, the calender method is the most productive method. In this field, the emergence of an ABS resin composition that can be formed and processed by the calender method without impairing the properties of the ABS resin. Is strongly desired. Therefore, various types of lubricants such as metal soaps, fatty acid amide lubricants, fatty acids, aliphatic alcohol lubricants, hydrocarbon lubricants, and aliphatic ester lubricants have been studied. I couldn't get it. Further, when the resin is kneaded with a roll using these lubricants, there is a disadvantage that the resin is colored.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems in the prior art, and to provide roll release properties, long run properties,
AB which is excellent in heat stability and suitable for calendering without coloring
An object of the present invention is to provide an S resin.

[0004]

Means for solving the above problems are as follows. In other words, one or more aliphatic phosphate compounds are mixed with the ABS resin. By blending the aliphatic phosphate ester compound, sufficient roll releasability and long run property can be obtained, and when a sheet material is formed by the calendar method, the roll separation is good, and the surface is not rough and smooth. Get the surface,
It is possible to provide an ABS resin composition in which the product and the roll separation do not change even when the product is continuously molded by a long-term calender. Further, by further blending at least one of a phenolic antioxidant and a polyhydric alcohol compound with the above composition, it is possible to provide an ABS resin composition having better heat stability.

The aliphatic phosphate compound in the present invention is a mono-, di- or tri-phosphate compound of a saturated or unsaturated higher alcohol having 6 to 30 carbon atoms and phosphoric acid, and a metal salt thereof. is there. Representative examples thereof will be given, but not limited thereto.

With respect to 0 parts by weight, 0.05 to 5.0 parts by weight, preferably 0.1 to 2.0 parts by weight is good. If the addition amount is less than 0.05 part by weight, the roll releasability is insufficient, and if it is more than 5.0 parts by weight, there is a possibility that it will emerge on the surface, and it is not economically good.
