Description

Technical Field

[0001] The invention relates to the field of material science and polymer engineering technology, in particular to high-strength wear-resistant nylon and a processing technology thereof. Background Art

[0002] Although existing nylon has good toughness, fatigue resistance and corrosion resistance, its low strength and low wear resistance limit its application in certain high-demand occasions. In order to overcome these shortcomings, researchers have adopted a variety of modification techniques, including physical modification and chemical modification. Physical modification usually involves adding various fillers such as fibers, inorganic particles, etc., while chemical modification improves material properties through methods such as block and graft copolymerization. However, these methods often sacrifice the performance of another aspect while improving the performance of one aspect, such as improving wear resistance while reducing the toughness of the material.

[0027] Compared with the prior art, the present invention provides high-strength wear-resistant nylon and its processing technology, which has the following beneficial effects:

[0028] 1. The present invention adopts a composite formula of enhanced polyamide resin and nano-level wear-resistant additive in the raw material formula. Since the heat deformation temperature of the enhanced polyamide resin is relatively high, the nylon finished product can still maintain the stability of its shape and size under high temperature environment and is not easy to deform. The nano-level wear-resistant additive has high hardness and high wear resistance due to its nano-level particle size, so that the additive can form hard particles in the nylon matrix, effectively resisting wear and scratches, and extending the service life of the product. At the same time, the nanoparticles can be evenly dispersed in the nylon matrix, avoiding the problem of uneven performance caused by agglomeration of traditional fillers. This uniform dispersion ensures that the product has consistent wear resistance in all directions. The combination of the two materials not only improves the dispersibility and fusion of the nylon finished product, but also increases the wear resistance and mechanical strength of the nylon finished product.

[0029] 2. The present invention adopts a twin-screw extrusion molding process, and then controls the temperature, pressure and shear rate of the twin-screw extruder within a preset range, which helps to control the rheological properties of the material, so that the molecular distribution of the nylon finished product is more uniform and the mechanical properties are optimized.

[0035] Nano-level wear-resistant additives: The nano-level particle size of nano-level wear-resistant additives has high surface hardness and wear resistance, which enables the additives to form hard particles in the nylon matrix, effectively resisting wear and scratches, and extending the service life of the product. In addition, the nanoparticles can be evenly dispersed in the nylon matrix, avoiding the uneven performance problem caused by agglomeration of traditional fillers. This uniform dispersion ensures that the nylon finished product has consistent wear resistance in all directions.

[0044] Step 4: Extrusion molding: Use a twin-screw extruder for melt extrusion molding to control the rheological properties of the material;

[0045] Step 5. Extrusion process parameters: Adjusting the screw speed, feed screw speed, screw and barrel temperature and feed rate parameters will help optimize the mixing, plasticizing and extrusion efficiency of the material;

[0064] Comparative Example 3

[0065] High-strength wear-resistant nylon, the raw materials of nylon and their weight parts are: 20 weight parts of carbon fiber reinforced PA; 12 weight parts of E-glass fiber reinforced PA; 4 weight parts of bio-based furanyl chloride derived aromatic polyamide resin; 6 weight parts of polyether ester amide block copolymer; 1.2 weight parts of talc filled PA; 1.9 weight parts of montmorillonite powder; 0.32 weight parts of aramid powder; 0.19 weight parts of antioxidant 1098; 0.58 weight parts of coupling agent (the particle sizes of montmorillonite powder, manganese powder and aramid powder are all between 200 and 300 nanometers).

[0066] A factory made finished nylon using the raw material formulas of Examples 1-3 and Comparative Examples 1-3 according to the processing technology of the present invention, and conducted flame retardant grade test, high temperature tensile test, compression modulus, impact elasticity, peel strength, water content, hardness, heat deformation temperature, melt index, thickness, combustion performance, compression permanent deformation and whiteness test on the nylon made therefrom. The experimental data are shown in Table 1 below:

[0067] Table 1

[0068]

[0069]

[0070] The effects of the raw material formula composition of Example 1 vs. Comparative Example 1, Example 2 vs. Comparative Example 2, and Example 3 vs. Comparative Example 3 on the performance of the nylon finished product are summarized as follows:

[0071] 1. Comparison of Example 1 Comparison of Comparative Example 1:

[0072] Example 1 uses 21 parts by weight of carbon fiber reinforced PA, while Comparative Example 1 does not use carbon fiber reinforced PA, but adds 2 parts by weight of E-glass fiber reinforced PA. It can be seen from the data in Table 1 that the carbon fiber reinforced PA makes the nylon finished product of Example 1 better than Comparative Example 1 in high temperature tensile strength and compression modulus performance. At the same time, Example 1 uses 4 parts by weight of bio-based furanoyl chloride derived aromatic polyamide resin, while Comparative Example 1 uses 14 parts by weight. The appropriate amount of bio-based furanoyl chloride derived aromatic polyamide resin in Example 1 can improve the heat resistance and dimensional stability of the material, but excessive addition in Comparative Example 1 will affect processing fluidity.

[0073] 2. Comparison between Example 2 and Comparative Example 2:

[0074] Example 2 uses 23 parts by weight of carbon fiber reinforced PA and 14 parts by weight of E-type glass fiber reinforced PA, while Comparative Example 2 uses 23 parts by weight of carbon fiber reinforced PA and 5 parts by weight of bio-based furanyl chloride-derived aromatic polyamide resin and 17 parts by weight of polyether ester amide block copolymer. The experimental data in Table 1 show that the rigidity and heat resistance of the nylon finished product of Example 2 are better than those of Comparative Example 2. Table 1 shows that the combination of carbon fiber reinforced PA and E-type glass fiber reinforced PA in the raw material formula helps to improve the rigidity and heat resistance of the finished product. At the same time, Example 2 uses 5 parts by weight of bio-based furanyl chloride-derived aromatic polyamide resin. amide resin and 7 parts by weight of polyetheresteramide block copolymer, while Comparative Example 2 used 5 parts by weight of bio-based furanyl chloride derived aromatic polyamide resin and 17 parts by weight of polyetheresteramide block copolymer. The experimental data in Table 1 show that the toughness and wear resistance of the nylon finished product of Example 2 are better than those of Comparative Example 2. Therefore, it is concluded that the combination of the reinforced polyamide resin and the polyetheresteramide block copolymer in the raw material formula ratio of Example 2 can improve the toughness and wear resistance of the material, but Comparative Example 2 lacks some reinforced polyamide resin, and excessive polyetheresteramide block copolymer will lead to increased material cost and increased processing difficulty.

[0075] 3. Comparison between Example 3 and Comparative Example 3:

[0076] The montmorillonite powder, manganese powder and aramid powder in Example 3 together constitute a nano-level wear-resistant additive, and the particle sizes are all between 80-100 nanometers, all reaching the nano level, while the particle sizes in Comparative Example 3 are all between 200-300 nanometers, all failing to reach the nano level. The data in Table 1 show that the wear resistance and mechanical properties of Example 3 are better than those of Comparative Example 3. Table 1 shows that the particle size of the nano-level wear-resistant additive helps to improve the wear resistance and mechanical properties of the nylon finished product, while the additive that does not reach the nano level cannot improve the wear resistance and mechanical properties of the nylon finished product.

[0077] In summary, the differences in raw material composition between Examples 1, 2, 3 and Comparative Examples 1, 2, 3 lead to different performance test results for different formulations, among which different combinations of nano-scale wear-resistant additives, carbon fiber reinforced PA and E-glass fiber reinforced PA, and changes in the addition amounts of bio-based furanyl chloride-derived aromatic polyamide resin and polyether ester amide block copolymer have different effects on the performance of the materials. The performance indicators of Examples 1-3 are all better than those of Comparative Examples 1-3, showing that the composite formulation of reinforced polyamide resin and nano-scale wear-resistant additives in the raw material formulation of the present invention can not only optimize the dispersibility and fusion of nylon finished products, but also improve the wear resistance and mechanical strength of the materials. Therefore, the formulation of the present invention is most effective in preparing high-strength wear-resistant nylon.

[0078] Example 4

[0079] The raw material formula of the invention is used and a twin-screw extrusion molding process is adopted to prepare the nylon finished product.

[0080] Comparative Example 4

[0081] The raw material formula of the invention is used and the melting and spinning technology is adopted to prepare the nylon finished product.

[0082] The molecular distribution and better mechanical properties of the nylon finished product prepared above were tested, and the data are shown in Table 2 below:

[0083] Table 2

[0084]

[0085]

[0086]

[0087] In summary, by comparing and analyzing Example 4 and Comparative Example 4, it can be seen that the test results of molecular distribution and multiple mechanical properties of Example 4 using the twin-screw extrusion molding process are better than those of Comparative Example 4 using the melting and spinning technology. This means that the twin-screw extrusion molding process used in the present invention can control the rheological properties of the material by setting the range of temperature, pressure and shear rate in advance, which not only makes the molecular distribution of the nylon finished product more uniform, but also makes the mechanical properties of the finished product reach the best.
