Description
Technical field
The present invention relates to polymer composite production equipment field, especially relate to a kind of equipment that continuous-filament woven fabric strengthens thermoplastic polyurethane of producing.
Background technology
Fiber reinforced thermolplastic composite material, due to its excellent mechanical performance, is more and more applied in recent years in life, as household electrical appliances electronic apparatus, military composite, automobile etc.It is high that this thermoplastic matrix's composite has mechanical strength, the metals such as alternative iron and steel, and quality is light, can reuse, and the feature of environmental protection is good.
But thermoplastic resin melt viscosity is greatly to limit a key factor of its development.High melt-viscosity makes the effect of impregnation of itself and fiber very poor, easily produces dry yarn.In order to increase the effect of impregnation of resin and fabric, great majority can adopt thermoplastic resin powder to be dispersed in uniformly on continuous-filament woven fabric, after heating and melting, form the composite of homogeneous, as patent US2005021514.8, introduce a kind of toner that can allow and be evenly distributed in the equipment on fiber, the diameter range of this equipment requirement particle, at 1-2000um, can obtain the good prepreg tape of complete bubble-free dipping under packing pressure effect.This kind of method is mainly that the fluid unit cost adopting in plastic powders and continuous fiber mixed process is higher.
The product of the relevant thermoplastic composite of domestic Ye You small part enterprise, for example compound prepreg tape of continuous fiber reinforced thermoplastic of Liaoning Liao Jie new material Science and Technology Ltd., the sale of composite board.The prepreg tape of the said firm adopts continuous fiber and thermoplastic resin melt melt impregnation, patent CN20091004897.3 has introduced the production equipment of the said firm, adopt one group staggered can the two extrusion dies of folding, the two extrusion die groups of this folding are by two parallel extrusion dies 1, extrusion die 2 and orbital motion installation composition.The main advantage of this equipment is that fiber and resin flood well under two folding die head groups, not dry yarn, and dipping process is controlled, and resin content is controlled.But because thermoplastic resin melt viscosity is larger, in this compound prepreg tape, fiber content is difficult to surpass 60%.
In addition, TPUE (TPU) is with the processing features of plastics and the physical and mechanical properties of rubber, not only there is remarkable high-tension, high-tensile strength, obdurability and ageing-resistant feature, and or ripe environment-friendly materials, there is the incomparable characteristic of other plastic, rubbers, as high in intensity, good toughness, abrasion-proof and cold-resistant, oil resistant is ageing-resistant, against weather is good etc., also has many special functions such as good waterproof performance, antibacterial thermal insulating, uvioresistant simultaneously.And in processing, shaping speed is fast, is easy to the demoulding, and hardness is adjustable.Polyurethane elastomer based composites has good storage stability, good mechanical property, and at building, automobile, aviation, energy industry (wind power plant), shipbuilding industry etc. are widely used.
Summary of the invention
Object of the present invention is exactly to provide a kind of equipment that continuous-filament woven fabric strengthens thermoplastic polyurethane of producing in order to overcome the defect of above-mentioned prior art existence, this equipment adopts A, the B batch can liquid of response type to mix rear and continuous-filament woven fabric dipping, it is good that the reinforcing material of preparation has dipping, porosity is low, thickness is adjustable, glass fiber content is high, more than can reaching 70Wt%, and it is simple to have production line, equipment can be realized high efficiency continuously and produce, and in production process without any the advantages such as environmental pollution.
Object of the present invention can be achieved through the following technical solutions:
Produce the equipment that continuous-filament woven fabric strengthens thermoplastic polyurethane, this equipment comprises that the unwinding device, tenslator, static eraser, preheating apparatus, immersion system, the heating that set gradually are ripening device used, cooling device and wrap-up;
