Problems solved by technology

This patent document also discloses a method for preparing a composite traction belt. In this method, the braided traction belt is soaked and then squeezed out of excess liquid through a squeeze wheel to form it. Since the braided fabric is directly used as a load-bearing phase and impregnated with a thermoplastic resin material, Not only the transverse fiber reinforcement is added, but also the prepared thicker fiber fabric is relatively poor in impregnation, which affects the performance of the prepared composite traction belt to a certain extent

Embodiment 1

[0038] by figure 1 The traction belt composed of 4 layers and 4 columns (4×4 structure) composite material reinforcement sheet is shown as an example. The untwisted continuous fiber in the composite material reinforcement sheet is selected from carbon fiber, and the thermosetting resin in the composite material reinforcement sheet is epoxy resin. , The thermoplastic resin constituting the matrix is ​​polyurethane resin.

[0039] Select 24 T300 continuous carbon fiber clusters treated with sizing agent, and place them on the fiber reel 2 on the creel 1 respectively. Set the temperature of the pultrusion mold 8 to 150-180° C., and start to preheat the pultrusion mold 8 . Mix the selected epoxy resin and its curing agent evenly, and add it into the dipping tank 3.

[0040] Start the forming device for the composite material reinforcing sheet, adjust the continuous fiber yarn cluster and the spreading roller 4, so that the carbon fiber is evenly spread out, and the tension force...

Embodiment 2

[0046] Figure 5 Shown is a 6×4 structural carbon fiber reinforced epoxy resin and thermoplastic polyurethane resin hybrid composite ultra-lightweight traction belt

[0047] The preparation process of the continuous fiber reinforced thermosetting composite material sheet is similar to the preparation process of Example 1, the main difference is that the number of continuous fiber yarn clusters in the embodiment is adjusted from 24 to 16, and 4 relatively thin continuous composite material sheets are obtained material, and repeated 5 times to obtain 24 continuous sheets of continuous carbon fiber reinforced thermosetting epoxy resin composites.

[0048] The preparation process of the continuous carbon fiber-reinforced hybrid composite traction belt is similar to the preparation process in Example 1, the main difference is that the 4×4 die in Example 1 is replaced with a 6×4 extrusion die to prepare Figure 5 Continuous carbon fiber reinforced epoxy resin and thermoplastic poly...

Embodiment 3

[0051] preparation figure 1 The shown 4×4 carbon fiber reinforced vinyl resin and thermoplastic polyurethane resin hybrid composite ultra-light traction belt, its implementation process is similar to that of Example 1, only the epoxy resin in Example 1 is replaced with vinyl resin , and reset the temperature of the pultrusion mold to 140-190° C., and the rest of the process and parameters and equipment are the same as in Example 1. The composite traction belt of Example 3 can be prepared.

[0052] Compared with the existing steel wire reinforced traction belt with the same size, the tensile performance of the prepared composite material traction belt is more than 1.6 times, and the weight is only 1 / 5 of the steel wire reinforced traction belt.

Abstract

The invention discloses a preparation method and a preparation system for an ultralight composite traction belt, and provides a preparation method and a preparation system for the ultralight composite traction belt with uniform bearing and long service life. The preparation method comprises the following steps: a twist-free continuous monofilament is led out of a fiber yarn group, unfolded uniformly, and introduced into an impregnation tank for impregnation, wherein the impregnation tank is added with a glue solution, then arrangement is performed, and composite enhanced pieces are obtained after pultrusion and curing; the composite enhanced pieces are led out respectively, preheated and introduced into a head die of an extruder, an extruding die core corresponding to the section of the traction belt is arranged in the head die, the composite enhanced pieces are uniformly coated with molten thermoplastic resin in the head die and led out of the head die of the extruder, preliminary forming is realized, and the traction belt is obtained after cooling setting and cooling. The prepared traction belt is light in weight, high in strength, easy to bend, anti-fatigue, long in service life, low in maintenance cost and more applicable to a long-distance elevator.

Description

technical field [0001] The invention relates to a preparation method and a preparation system of an ultra-light composite traction belt. Background technique [0002] The traction belts of long-distance passenger / or cargo hoists (such as elevators) are generally made of steel wire rope reinforced flexible thermoplastic composite materials. Due to the large specificity and low strength of the steel wire itself, the prepared traction belts are not only heavy when used. , low strength, and large size, resulting in a large size of the matching traction wheel, the power of the traction equipment increases, and the energy consumption of the hoist is greatly increased, which is not conducive to energy saving, environmental protection and long-term use. [0003] With the continuous advancement of technology, composite traction belts have emerged as the times require. The patent document with publication number CN102002872A and invention titled "Fiber Braided Flexible Composite Trac...
