The sheet material is prepared from the following components in percentage by weight: 90-96 percent of universal polystyrene and 4-10 percent of additive. The manufacture method comprises the following steps: mixing 90-96 percent by weight of universal polystyrene and 4-10 percent of additive; carrying out melt extrusion on the mixture at 180-250 DEG through an extruder; feeding the molten material into a die head, and casting a sheet at 200-250 DEG C; longitudinally and transversely stretching and molding the sheet to obtain a flake; and trimming the flake, measuring the thickness of the flake, rolling, aging and slitting. According to the manufacture method, the melting temperature of the extruder and the temperature of the die head are reasonably controlled, so that uniform thickness and thinness of the manufactured polystyrene sheet material can be guaranteed; the toughness of the sheet material is strengthened due to reasonable control on the preheating temperatures of longitudinal stretching and transverse stretching and application of the additive, so that the market requirement is greatly met.

Technical field
The present invention relates to technical field of polymer materials, relate in particular to biaxially oriented polystyrene sheet material and manufacture method thereof that a kind of environmental protection can be used for printing.
Background technology
Biaxially oriented polystyrene film is a kind of novel green wrapping material that development in recent years is got up, the polyethylene, the polyvinyl chloride film etc. that use compared with tradition, it has that intensity is high, rigidity is large, nontoxicity, easily degraded, easy coloring, have good glossiness and transparency, the advantage such as easy to process, be widely used in all kinds of article if artwork, daily necessities, metal products are particularly in the packaging of food.Developed countries at present, as the biaxially oriented polystyrene film consumption of the U.S., Canada, Japan etc., oneself accounts for the more than 60% of all film classes.
But, there are many weak points in common polystyrene material, as low in fragility, shock strength, be prone to cracking, fire-retardant fireproof is poor, weathering resistance is bad, heat-drawn wire is low etc., and because the current control temperature generally adopting in process of production makes the polystyrene film thickness produced excessive, can not meet the day by day wide application demand of client, these shortcomings have all limited the range of application of polystyrene greatly.
Thereby, need not reduce under the prerequisite of polystyrene material physical properties at present, need badly material produce technique is improved to obtain the biaxially oriented polystyrene that thinness controllability is strong and uniformity coefficient is high, meet the current market requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide biaxially oriented polystyrene sheet material and the manufacture method thereof that a kind of environmental protection can be used for printing, in improving resistance to impact shock, tensile strength, improves thinness controllability and thickness evenness.
For solving the problems of the technologies described above, the object of the invention is to be achieved through the following technical solutions.
Environmental protection can be used for a biaxially oriented polystyrene sheet material for printing, and its composition is (%) by weight ratio:
General Purpose Polystyrenre 90-96%;
Additive 4-10%; Described additive comprises K resin and high-impact polystyrene.
Preferably, the weight proportion of described General Purpose Polystyrenre is 92-96%, and the weight proportion of additive is 4-8%.
A manufacture method for biaxially oriented polystyrene sheet material described above, comprises step:
(1) General Purpose Polystyrenre of 90-96% and the additive of 4-10% are fully uniformly mixed resulting mixture by weight percentage;
(2) by described mixture by forcing machine through melt extruding, melt temperature is controlled between 180 DEG C to 250 DEG C;
(3) melts is sent into die head and extrude, cast sheet, in die head, temperature is controlled between 200 DEG C to 250 DEG C;
(4) sheet is first carried out to preheating on vertical drawing machine, carry out longitudinal stretching and sizing simultaneously; On horizontal drawing machine, carry out again preheating, carry out cross directional stretch and sizing simultaneously, obtain thin slice;
(5) described thin slice is carried out to deburring and thickness measuring, then carry out cutting after rolling, ageing treatment.
Preferably, between described step (1) and (2), also comprise step: described mixture is dropped into blower fan hopper, blow to moisture eliminator and carry out drying treatment through roots blower.
Preferably, in described step (3), by vacuum pump, mixture after treatment drying is drawn to the hopper of forcing machine.
Preferably, the preheating temperature of described vertical drawing machine is controlled between 50 DEG C to 150 DEG C.
Preferably, the preheating temperature of described horizontal drawing machine is controlled between 100 DEG C to 150 DEG C.
The present invention has following beneficial effect:
The present invention rationally controls by the melt temperature to forcing machine and die head temperature, can guarantee that even thickness and the thinness of produced polystyrene sheet material is controlled; By the reasonable control of the preheating temperature to longitudinal stretching and cross directional stretch and the application of additive, strengthen the toughness of sheet material, thereby greatly met the market requirement.
Brief description of the drawings
Fig. 1 is preparation method's schema of the polystyrene sheet material that provides of the embodiment of the present invention.
