The reinforced polycarbonate materials of examples 1 to 10 described above were excellent in bending resistance, good in toughness and good in appearance.
Compared with the polycarbonate material in the example 1, the polycarbonate materials in the comparative examples 1 and 2 respectively adopt wollastonite with the length-diameter ratio of 3:1 and 17:1, so that the product has poor toughness, poor bending resistance, poor toughness and poor appearance performance. Mainly because wollastonite has too small length-diameter ratio, energy is not easy to transfer when the wollastonite is impacted, cracks are easier to initiate, toughness is poor, and the length-diameter ratio is low and strength is also low, so that bending resistance is poor; the length-diameter ratio is too large, and as a defect point, the interface combination is poor due to stress concentration, so that the toughness is poor, the bending resistance is poor, and the appearance performance is poor;
in the polycarbonate materials of comparative examples 3 and 4, modified polyethylene waxes having acid numbers of 2KOHmg/g and 100KOHmg/g, respectively, were used, and the acid of the modified polyethylene wax was able to counteract the degradation of PC catalyzed by wollastonite when the degree of reaction of the acid of the modified polyethylene wax with the PC end groups corresponds to the acid number, as compared with example 1. When the acid value of the modified polyethylene wax is too low, the degradation of PC catalyzed by wollastonite is not sufficiently counteracted, so that the material has poor bending resistance, poor toughness and poor appearance performance. When the acid value is too large, unreacted acid in the modified polyethylene wax can catalyze PC degradation, so that the material has poor bending resistance, poor toughness and poor appearance performance.
In the polycarbonate material of comparative example 5, polyethylene wax was used as a lubricant, and the polyethylene wax was capable of reacting with wollastonite, and the wollastonite catalyzes PC degradation, resulting in poor bending resistance, poor toughness and poor appearance. Compared with example 1, the polycarbonate material of comparative example 6 is poor in bending resistance, toughness and appearance performance due to the fact that wollastonite catalyzes PC degradation without adding modified polyethylene wax.
Compared with example 1, the polycarbonate material of comparative example 7 is not added with wollastonite, and the modified polyethylene wax is acid-catalyzed by PC degradation, so that the material has poor bending resistance, poor toughness and poor appearance performance.
In the polycarbonate material of comparative example 8, the mass part ratio of wollastonite to modified polyethylene wax is 20:1, compared with example 1; in the polycarbonate material of the comparative example 9, the mass ratio of wollastonite to modified polyethylene wax is 60:1; when the mass ratio of the wollastonite to the modified polyethylene wax is 60:1, the polyethylene wax is too low to offset the degradation of PC catalyzed by the wollastonite, so that the material has poor bending resistance, poor toughness and poor appearance performance; when the mass ratio of wollastonite to modified polyethylene wax is 20:1, the polyethylene wax is excessive, and unreacted acid in the modified polyethylene wax can catalyze PC degradation, so that the material has poor bending resistance, poor toughness and poor appearance performance.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted equally without departing from the spirit and scope of the technical solution of the present invention.
