Abstract
The utility model discloses a kind of high tenacity PC/PBT plastic alloys template reinforcing material, including one layer of polycarbonate and polybutylene terephthalate (PBT) PBT plastic alloy, layer of glass cloth replaces compound multilayer template reinforcing material.The template reinforcing material has more excellent mechanical property and processability, can be widely applied to the fields such as building, electronics, automobile, chemical industry.
Description
Technical field
The utility model is related to a kind of high tenacity PC/PBT plastic alloys template reinforcing materials, and in particular to a kind of glass fibers
Wei Bu enhances the high toughness plastic alloy template reinforcing material of PC/PBT.
Background technology
Polycarbonate has good shock resistance, and electrical property, chemical resistance, good fluidity, translucency is strong,
It is a kind of multi-functional thermoplastic engineering plastic of excellent performance, but it wears no resistance, product internal stress is big, notch sensitivity
Height needs to be modified to make up the defect in its performance.
Polybutylene terephthalate (PBT) PBT is that a kind of colorless and odorless is poly- from transparent to translucent crystal type thermoplastics type
Ether has wear-resisting property outstanding, heat aging performance, higher mechanical strength, obdurability, heat-proof water, acid and oils.It also has
Alkali resistance is poor, notch sensitivity, the shortcomings of shrinking percentage is larger.
Polycarbonate/polybutylene terephthalate (PBT) PBT（Hereinafter referred to as PC/PBT）Alloy has good processing
Mobility, low-temperature impact resistance, good chemical-resistance and weatherability, cost performance is good, is a kind of with PC/ABS similar performances
Ideal alloy material.
PBT and PC has good performance complement, but the PC/PBT alloy materials for lacking commercialization are thrown away by the country, while
Lack its occasion used, the present invention mainly starts with from technique, releases a kind of suitable for fields such as building, electronics, automobile, chemical industry
Multilayer reinforcing material, enrich market product type.
Utility model content
To achieve the above object, the utility model discloses a kind of novel high tenacity PC/PBT plastic alloy templates enhancings
Material, using following technical proposals：
Processing method is characterized as：
（1）Using layer of glass cloth as inner core；
（2）After PC/PBT is melted using pressure roll, spraying or stream along etc. mode single or double be coated in glass
Fiber cloth surface；
（3）Layer of glass cloth is pressed on it by way of hot pressing again after the cooling of surface layer, repetition thickens.
Wherein, total number of plies of PC/PBT plastic alloys and glass fabric is 2-10 layers.
Wherein, glass fabric thickness is 01-08 type glass fabrics, preferably 03 type glass-fiber-fabric.
Wherein, PC/PBT fusant is coated in glass using the mode of pressure roll, spraying or stream edge after PC/PBT meltings
Surface, it is cooling to obtain semifinished sheet 1 to coat layer thickness being 0.1-3mm.
Wherein, the semifinished sheet 1 and glass fabric that have cooled down are passed through into hot press, the roller bearing temperature of hot press together
It is 160-220 DEG C, hot pressing time 1-3min, pressure 0.1-20kpa.
The utility model has following characteristics：
1. the utility model good impact resistance, glass fabric improves the original notch sensitivity of PC/PBT alloys, resistance to
Mill property, the shortcomings of stress is big, by the molding ability in blocks of glass fabric, greatly enhance the performance of PC/PBT；
2. the utility model can adjust glass fabric and the thickness of PC/PBT as the case may be, interlayer is increased or decreased
Thickness, to reach the requirement of some special planks；
3. the utility model has the plastic alloy material than extrusion forming after melting in the market and has better mechanical property
Can, it is more standby competitive in terms of reinforcing material.
Description of the drawings：
To keep the utility model more intuitive, the utility model is further described in attached drawing 1：
1 is PC/PBT plastic alloy layers
2 be fiberglass cloth
Specific implementation mode：
Referring to Figure of description.The template composite material is one layer of PC/PBT plastic alloy, and layer of glass cloth is answered
Close laminar structure.
Step 1：Centered on glass fabric, the PC/PBT plastic alloys melted are sprayed on glass fabric,
It waits for its infiltration covering completely, using cast film machine, waits for that its curtain coating is complete, it is cooling.
Step 2：Semifinished sheet after cooling is placed among layer glass fiber cloth, hot press, hot pressing temperature are adjusted
It is 220 DEG C, hot pressing temperature 2min, pressure 3kpa.
Layer glass fiber cloth is pressed together on semifinished sheet using forcing press.
Step 1 and step 2 are repeated, thickness and the number of plies until reaching product needs.
Claims (5)
1. a kind of high tenacity PC/PBT plastic alloys template reinforcing material, it is characterized in that：Including one layer of polycarbonate and poly- pair
Benzene dicarboxylic acid butanediol ester PBT plastic alloy, layer of glass cloth replace compound multilayer template reinforcing material.
