Description
Technical Field
The invention belongs to the field of polyethylene fibers, and in particular relates to a light creep-resistant high-performance polyethylene composite material and a preparation method thereof.
Background
Ultra-high molecular weight polyethylene fibers are third generation high performance fibers occurring subsequent to carbon fibers and aramid fibers, having mechanical properties incomparable with other high performance fibers, and are widely used in the fields of military bulletproof, safety protection, aerospace navigation engineering, high performance, light weight composite materials, sports equipment, and the like, for example, in such fields as ropes, fishing nets, medical devices, fabrics, laminates, composite products, and bulletproof clothing, cut-proof fabrics, cables, and the like.
However, because the ultra-high molecular weight polyethylene molecules themselves are composed of only methylene groups, there is no polar force between the molecules, the surface of the fiber is chemically inert, and the highly crystalline, highly oriented smooth surface formed by high-power drawing of the fiber is added, so that the ultra-high molecular weight polyethylene fiber itself has many defects, such as poor heat resistance (up to 70 ℃), and the service temperature of the fiber is limited. The ultimate failure mode of systems using ultra high molecular weight polyethylene fibers, particularly those placed under load for long periods of time, is due to creep, particularly at elevated temperatures, which is more problematic. Thus, such systems, particularly those intended for long or ultra-long term use, must be designed to last sufficiently for many years, for example, more than 10 years, and in some cases, more than 30 years. The ease of creep limits the use of such fibers in related professional applications.
Therefore, a light creep-resistant high-performance polyethylene composite material and a preparation method thereof are needed to be proposed.

According to the invention, preferably, the stretching temperature is 90-180 ℃.
According to the invention, the light creep-resistant high-performance polyethylene composite preferably has a monofilament strength of 39-45CN/dex and a modulus of 1950-2500CN/dex.
The technical scheme of the invention has the following beneficial effects:
according to the invention, on the basis of ensuring the light weight of the polyethylene composite material, the creep resistance of the material is improved from chemical and physical angles by using the carbon nano tube and the glass fiber respectively, namely, the acting force is generated between the carbon nano tube and the ultra-high molecular weight polyethylene molecular chain, so that the creep resistance of the ultra-high molecular weight polyethylene is improved; the glass fiber and the ultra-high molecular weight polyethylene are mixed in the melt spinning and the subsequent steps, so that the mechanical property of the polyethylene composite material is enhanced.
Meanwhile, the polyethylene terephthalate with high creep resistance, fatigue resistance, friction resistance and high-temperature stability is selected to participate in the preparation of the polyethylene composite material, so that the mechanical properties of the polyethylene composite material are basically unchanged in a long-term high-temperature environment, and the polyethylene composite material has the properties of high heat resistance, high creep resistance and the like.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
Detailed Description
Preferred embodiments of the present invention will be described in more detail below. While the preferred embodiments of the present invention are described below, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The components of each of the examples below are commercially available.
Example 1
The embodiment provides a light creep-resistant high-performance polyethylene composite material, which comprises the following components in parts by weight: 0.9 part of carbon nano tube, 0.25 part of chopped alkali-free glass fiber (length is 4mm, and monofilament diameter is 10-15 mu m), 95 parts of ultra-high molecular weight polyethylene (average molecular weight is more than 100 ten thousand, specific gravity is 0.97), 13 parts of polyethylene terephthalate, 2000.05 parts of polyethylene glycol and 2 parts of epoxy resin.
The preparation method of the light creep-resistant high-performance polyethylene composite material comprises the following steps:
s1: mixing and melting the carbon nano tube, glass fiber, ultra-high molecular weight polyethylene, polyethylene terephthalate, dispersing agent and epoxy resin at 150 ℃ to obtain ultra-high molecular weight polyethylene fiber spinning solution;
s2: extruding and spinning the ultra-high molecular weight polyethylene fiber spinning solution (the temperature is 200 ℃) and volatilizing the redundant solution (the temperature is 250 ℃) in sequence to form dry state precursor;
s3: and (3) stretching the dry precursor (the temperature is 170-180 ℃) to obtain the light creep-resistant high-performance polyethylene composite material.
Example 2
This example provides a light creep-resistant high performance polyethylene composite, which differs from example 1 only in that: the polyethylene terephthalate was 12 parts.
Example 3
This example provides a light creep-resistant high performance polyethylene composite, which differs from example 1 only in that: the polyethylene terephthalate was 14 parts.
Comparative example 1
This comparative example provides a polyethylene composite material, which differs from example 1 only in that:
the temperature of the mixed melting is 250 ℃;
the temperature of the extrusion spinning is 300 ℃;
the temperature at which the excess solution volatilized was 350 ℃.
Comparative example 2
This comparative example provides a polyethylene composite material, which differs from example 1 only in that: the polyethylene composite material does not contain carbon nano tubes and chopped alkali-free glass fibers.
Test case
This test example the polyethylene composites obtained in examples 1-3 and comparative examples 1-2 were tested for heat resistance and creep elongation, wherein:
test of heat resistance: after aging the test pieces in an oven air atmosphere at 115℃for 100 hours, the polyethylene composites obtained in examples 1-3 and comparative examples 1-2 were tested for breaking strength and elongation at break according to GBT 19975-2005.
Test of creep elongation: the tensile creep test method specified in the GBT 19975-2005 high strength fiber filament tensile property test method is adopted, wherein the load is 50% of the breaking load of the fiber, and the test temperature is 70 ℃.
The test results are shown in Table 1.
TABLE 1
As is apparent from the comparison of examples 1 to 3 and comparative example 1 in Table 1 above, the polyethylene terephthalate has an effect on the heat resistance of the polyethylene composite material, and increasing the amount of polyethylene terephthalate increases the heat resistance of the polyethylene composite material, while comparative example 1 increases the temperature of each step of the production process, but the heat resistance, breaking strength, breaking elongation, and the like of the polyethylene composite material are hardly affected under the protection of the polyethylene composite material by the polyethylene terephthalate.
From the comparison of examples 1-3 and comparative example 2 in Table 1 above, the lack of carbon nanotubes and chopped alkali-free glass fibers will have a large impact on the creep elongation of the polyethylene composite, demonstrating that the selection of carbon nanotubes and chopped alkali-free glass fibers in combination with ultra-high molecular weight polyethylene according to the present invention can provide creep resistance to the polyethylene composite.
The foregoing description of embodiments of the invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described.
