The invention is further illustrated by the following specific examples, which are intended to be illustrative only and not limiting.
The raw materials used in the invention are as follows:
PC: bisphenol A type resin having molecular weight of 24000-27000;
PBT: 1.0 viscosity, chemical engineering of Changchun;
talc powder: ten thousand meshes;
permanent antistatic agent 1: polyamide-based permanent antistatic agent, NC 6321;
permanent antistatic agent 2: MV1074
Permanent antistatic agent 3: MH2030
A toughening agent: MBS core-shell modifier, specifically E920 or EXL 2616;
antioxidant: hindered phenol antioxidant and phosphite antioxidant, specifically antioxidant 1010, antioxidant 1076, antioxidant 168 or antioxidant PEPQ;
ester exchange inhibitor: one or more of ADK STAB AX-71, sodium dihydrogen phosphate or SA-PGP-B;
black master batch: is a PP substrate, and the carbon black content is 40 percent.
The product performance testing method comprises the following steps:
surface resistance: evaluating according to an IEC 60093 method;
notched impact strength: evaluation according to ISO 179;
tensile strength: evaluated according to ISO 178 method.
Specifically, the comparative example and examples 1-3 were conducted as follows:
and (2) mixing the dried raw materials, continuously and uniformly adding the mixture into a main machine cylinder of a double-screw extruder with the screw diameter of 35mm and the length-diameter ratio L/D of 36 by using a double-screw feeder, controlling the temperature of the main machine cylinder in sections, wherein the temperature is controlled from a feed inlet to a machine head outlet at 230 ℃, 240 ℃, 250 ℃, 245 ℃, 255 ℃ and the rotating speed of double screws is 300 revolutions per minute, and extruding strips are cooled by a water tank and then cut into particles to obtain the product. The product is dried in a forced air oven at 100 ℃ for 4 hours and then is injection molded into a standard sample strip by a plastic injection molding machine, and the injection molding temperature is 250 ℃. The injection molded bars were immediately placed in a glass desiccator for performance testing after at least 24 hours at room temperature. Wherein, the scheme design and the test results are shown in table 1.
TABLE 1.1 Performance test results for examples 1-3
As can be seen from the data in Table 1.1, the PC/PBT alloy material has reduced mechanical properties as a whole with the increase of the content of the permanent antistatic agent, but has improved antistatic properties (the reduction of the surface resistance means the improvement of the antistatic properties), but when the content of the permanent antistatic agent reaches a certain degree, the efficiency of the reduction of the surface resistance is also reduced (example 3), so that the formula in example 2 is preferred in order to obtain the PC/PBT alloy material with better antistatic properties and mechanical properties.
TABLE 1.2 Performance test results for comparative examples 1-4
As can be seen from the data in Table 1.2, after the PC and the PBT use the ester exchange inhibitor, the PC/PBT alloy material with normal performance and qualified appearance can be obtained, but the PC/PBT alloy material has low rigidity and low notch impact data, and the PC/PBT alloy material does not meet the use requirements of customers; the talc powder is added at the later stage to improve the rigidity of the whole material, which means that the notch impact strength data is further reduced, and a toughening agent needs to be supplemented to improve the rigidity of the whole material and ensure that the rigidity and the toughness are in a balanced state (comparative examples 2 and 3); meanwhile, in order to meet the use requirements of customers, the permanent antistatic agent is added to reduce the surface resistance of the material and improve the antistatic performance, so that the obtained overall material has better performance (comparative example 4).
