Performance test
1. Notched Izod 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, the test results being shown in Table 3.
2. Gloss (60 °): examples 1-11 and comparative examples 1-5 were tested according to GB/T8807-1988, standard bars were injection molded according to the standard, and the test results 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 at 220℃under 10kg, and the test results are shown in Table 3.
4. Elongation at break: examples 1-11 and comparative examples 1-5 were tested according to GB/T1040-1992 under 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
As can be seen from the performance detection results of the example 3 and the comparative examples 1 and 3 in the table 3, after the butyronitrile glove powder is prepared into the master batch, the notch impact performance of the prepared matrix resin is obviously superior to that of the prepared matrix resin obtained by directly adding the butyronitrile glove powder, and compared with the method that the material gloss of the butyronitrile glove added by the method of the comparative example 3 is better maintained as compared with that of the material obtained by simply adding the ABS resin; the reason is probably because the nitrile rubber is in a cross-linked network shape, the masterbatch is prepared and uniformly dispersed in the matrix resin which is the same as the carrier resin, a better reinforcing and toughening effect is achieved after secondary dispersion, the powdery nitrile is difficult to uniformly disperse in the matrix resin due to larger particle size, an agglomeration phenomenon exists, a good reinforcing and toughening effect cannot be achieved, the surface glossiness is obviously reduced, and the grinding of the nitrile glove into micron-sized powder is difficult to achieve although the grinding can be improved, and the difficulty and the cost are high.
As is clear from the results of the performance test of example 3 and comparative example 2 in Table 3, the amount of the nitrile rubber powder master batch added was large, the degree of crosslinking was severe during the melt extrusion, the notched impact strength was rather lowered, and the melt flow rate was drastically lowered with the increase of the rubber content.
As can be seen from the performance detection results of example 3 and comparative examples 4-5 in Table 3, the higher the crosslinking degree of the waste nitrile rubber glove, the lower the recycling value, and the more difficult the performance of the prepared product to meet the requirements, the dispersibility can be met without reaching the micron level by limiting the particle size of the nitrile rubber powder in the nitrile rubber powder master batch to below 0.5mm, the recycling value of the recycled waste with the Gao Dingjing rubber powder crosslinking degree of more than 80%, the prepared product can meet the higher performance requirements, and the ABS composite material prepared from the high-crosslinking-degree nitrile rubber powder has higher toughness and elongation at break, which indicates that the extensibility is superior.
The notch impact strength of the cantilever beam of the ABS composite material finally obtained by the embodiment of the application can reach 21kJ/m 2 The glossiness (60 degrees) 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 of the case and bag field can be met.
AS can be seen from the performance test results of examples 3 and 6 in table 3, the addition of the AS resin can further adjust the flowability and glossiness of the material, and the AS resin itself is one of the raw materials for synthesizing the ABS resin, has excellent compatibility with the composite material, has better flowability relative to the ABS resin itself, and the higher flowability of the AS resin is helpful to help the movement and dispersion of the nitrile rubber powder, and improves the reinforcing and toughening effects of the material.
As can be seen from the results of the performance tests of examples 3 and 8 to 10 in Table 3, when the content of the nitrile rubber powder in the nitrile rubber powder master batch is too large, the agglomeration phenomenon may be more serious because the powder content is too large, and instead there is a slight decrease in the melt flow rate and gloss properties.
The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present invention, and are not to be construed as limiting the scope of the invention. It should be noted that any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the spirit and principles of the present invention are intended to be included in the scope of the present invention.
