Description
Technical field
The present invention relates to PMMA films and its calendering technical field.
Background technology
PMMA has excellent translucency and weather resistance, but notch sensitive, and intensity and toughness are poor, if being made film,
Easy fracture.The existing processing to PMMA, mainly there is extrusion board, cast-sheet.And be made of the method for calendering relatively thin, softer
The PMMA films country yet there are no relevant report.
The content of the invention
The technical problem to be solved in the present invention is that to solve the problems, such as that PMMA materials are made frangible, easy to break after film, with suitable
With the method for calendering manufacture film.
To solve the technical scheme that above-mentioned technical problem is used：A kind of PMMA modified films, it is characterised in that：Include
The major ingredient of 80-100PHR PMMA, 0-10PHR EVA, 0-10PHR EMMA, 0-5PHR ABS and 0-5PHR MBS composition；It is main
The lubricant of material weight 0.1-10%；Major ingredient weight 0.1-10% antioxidant；Major ingredient weight 0.05-0.5% fillers；And major ingredient
Weight 0-10% pigment.
It may be preferred that the lubricant is at least one in stearic acid, stearate and wax class.
The antioxidant is at least one in 1010,1076 and 1068.
Described filler is CaCO3、SiO2, at least one in talcum powder and mica.
To solve the another technical scheme that above-mentioned technical problem is used：A kind of production method of PMMA modified films, its
It is characterised by comprising the following steps：
A, mix major ingredient in proportion, add part antioxidant, be put into kneader, it is uniform in low temperature mixing, to obtain
PMMA is material modified；
It is B, the PMMA is material modified in proportion plus lubricant, remaining antioxidant, filler and pigment, place into and pinch
Conjunction machine low temperature is uniformly mediated；
C, by the kneading material obtained by step B, sequentially pass through 120-180 DEG C of double screw extruder, 120-180 DEG C of mill
Machine, 160-200 DEG C of four-roll calender, 120-160 DEG C deflects from wheel, and 80-160 DEG C rear is batched, and wound membrane concentrates 80 DEG C and blow
Air cooling, the PMMA modified films of thickness needed for obtaining.
It may be preferred that the lubricant is at least one in stearic acid, stearate and wax class.
The antioxidant is at least one in 1010,1076 and 1068.
Described filler is CaCO3、SiO2, at least one in talcum powder and mica.
The beneficial effect brought using the present invention：Join process modification after to PMMA material modifications and calendering so that
PMMA toughnesss of material strengthen.Improve notch sensitivities of the PMMA when relatively thin film is made, enable to extract film out with calendering,
Simultaneously can also film forming batch.Widened PMMA machining kinds, the film of the obtained PMMA of calendering, enrich PMMA films it is secondary plus
The scope of work, makes it the film with other materials, sheet material laminating, so as to the excellent weather resistance reinforcement other materials of PMMA be existed
The weakness of this performance.Such as PMMA films are fitted with PVC film, then improve the weatherability of PVC.Meanwhile, calendering production is than curtain coating
Production PMMA film speeds are fast, efficiency high, and thin film strength and toughness are improved.
Specific embodiment
A kind of PMMA modified films, include 80-100PHR PMMA, 0-10PHR EVA, 0-10PHR EMMA, 0-5PHR
The major ingredient of ABS and 0-5PHR MBS compositions；The lubricant of major ingredient weight 0.1-10%；Major ingredient weight 0.1-10% antioxidant；
Major ingredient weight 0.05-0.5% fillers；And major ingredient weight 0-10% pigment.Its production method is comprised the following steps：
A, mix major ingredient in proportion, add part antioxidant, be put into kneader, it is uniform in low temperature mixing, to obtain
PMMA is material modified；
It is B, the PMMA is material modified in proportion plus lubricant, remaining antioxidant, filler and pigment, place into and pinch
Conjunction machine low temperature is uniformly mediated；
C, by the kneading material obtained by step B, sequentially pass through 120-180 DEG C of double screw extruder, 120-180 DEG C of mill
Machine, 160-200 DEG C of four-roll calender, 120-160 DEG C deflects from wheel, and 80-160 DEG C rear is batched, and wound membrane concentrates 80 DEG C and blow
