Performance test
1. Izod notched impact strength: examples 1-11 and comparative examples 1-5 were tested according to GB/T1843-2008 standard and injection molded into standard bars according to the standard, with the test results shown in Table 3.
2. Gloss (60 °): examples 1-11 and comparative examples 1-5 were tested according to GB/T8807-1988 and injection molded into standard bars according to the test standards, the results of which are shown in Table 3.
3. Melt flow rate: examples 1 to 11 and comparative examples 1 to 5 were tested according to GB/T3682-2000 under conditions of 220 ℃ and 10kg, and the test results are shown in Table 3.
4. Elongation at break: examples 1 to 11 and comparative examples 1 to 5 were tested according to GB/T1040-1992 under test conditions of 50 mm/min, and the test results are shown in Table 3.
TABLE 3 Performance test results for examples 1-11 and comparative examples 1-5
According to the performance detection results of the example 3 and the comparative examples 1 and 3 in the table 3, the notch impact performance of the prepared matrix resin is obviously superior to that of the matrix resin directly added with the butyronitrile glove powder after the butyronitrile glove powder is prepared into the master batch, and compared with the fact that the ABS resin material is simply added in the comparative example 3, the glossiness of the material added with the butyronitrile glove can be well maintained; the reason may be that the nitrile rubber is in a cross-linked network shape, the prepared master batch is uniformly dispersed in the matrix resin which is the same as the carrier resin, and a better reinforcing and toughening effect is achieved after secondary dispersion, while the powdery nitrile is difficult to uniformly disperse in the matrix resin due to a larger particle size, has an agglomeration phenomenon, cannot achieve a good reinforcing and toughening effect, and obviously reduces the surface gloss, and the degree of difficulty and the cost are higher and are difficult to achieve although the nitrile gloves are ground to micron-sized powder which can be improved.
The performance test results of example 3 and comparative example 2 in table 3 show that the addition amount of the nitrile rubber powder masterbatch is large, the degree of crosslinking is severe in the melt extrusion process, the notch impact strength is reduced on the contrary, and the melt flow rate is reduced rapidly along with the increase of the rubber content.
According to the performance detection results of the example 3 and the comparative examples 4 to 5 in the table 3, the higher the crosslinking degree of the waste nitrile rubber gloves is, the lower the recycling value of the gloves is, and the more difficult the performance of the prepared product is to meet the requirements, the particle size of the nitrile rubber powder in the nitrile rubber powder master batch is limited to be less than 0.5mm, the micron-sized particles are not required to reach, the dispersibility can be met, the recycling value of the recycled waste with the crosslinking degree of the nitrile rubber powder being more than 80% is improved, the prepared product can meet the higher performance requirements, and the ABS composite material prepared from the nitrile rubber powder with the high crosslinking degree has higher toughness and elongation at break, so that the elongation performance is superior.
The impact strength of the notch of the finally obtained ABS composite material cantilever beam can reach 21kJ/m 2 Above, the glossiness (60 ℃) reaches more than 80, the melt flow rate reaches more than 10g/10 min, the elongation at break reaches more than 18%, the extensibility is excellent, and the application requirements in the field of bags and bags can be met.
The performance test results of examples 3 and 6 in table 3 show that the addition of the AS resin can further adjust the fluidity and the glossiness of the material, the AS resin is one of the raw materials for synthesizing the ABS resin, has excellent compatibility with the composite material, and has better fluidity compared with the ABS resin, and the greater fluidity of the AS resin is helpful for assisting the movement and dispersion of the nitrile rubber powder, and improving the reinforcing and toughening effects of the material.
The performance test results of examples 3 and 8-10 in Table 3 show that when the content of the nitrile rubber powder in the nitrile rubber powder masterbatch is too high, agglomeration may be more serious due to too high powder content, and the melt flow rate and the gloss performance are slightly reduced.
The above-mentioned embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, and it should be understood that the above-mentioned embodiments are only examples of the present invention and are not intended to limit the scope of the present invention.
