Embodiment 1

[0027] After mixing each component in a mixer according to the weight ratio shown in Table 1, use a twin-screw extruder to granulate, and the granulation temperature is between 220°C and 250°C. The obtained particles were processed by injection molding according to the standards and methods described in the instructions, and the binding force and PI value were tested. The test results are shown in Table 1.

[0030]

[0031] a. Reference 1 is NMT material 1101G of Toray Corporation of Japan

[0032] b. Reference 2 is Mitsubishi LDS material 3730

[0033] Wherein EVA is ethylene-vinyl acetate copolymer.

[0034] From the properties of the reference materials in Table 1, it can be seen that the NMT and LDS products currently on the market cannot meet the requirements of the two processes at the same time. However, all samples in Table 1 have both NMT binding ability and LDS activity, and the NMT binding ability and LDS activity of most samples ...

Embodiment 2

[0036] After mixing each component in a mixer according to the weight ratio shown in Table 2, use a twin-screw extruder to granulate, and the granulation temperature is between 220 degrees Celsius and 250 degrees Celsius. The obtained particles were processed by injection molding according to the standards and methods described in the instructions, and the binding force and PI value were tested. The test results are shown in Table 2.

[0042] Wherein EVA is ethylene-vinyl acetate copolymer.

[0043] In Example 2, the influence of different other polyester resins on the NMT and LDS properties of the material was investigated. It can be seen from the data that the addition of other polyester resins can significantly improve the NMT binding force of the material, and at the same time, it has almost no nega...

Embodiment 3

[0045] After mixing each component in a mixer according to the weight ratio shown in Table 2, use a twin-screw extruder to granulate, and the granulation temperature is between 220 degrees Celsius and 250 degrees Celsius. The obtained particles were processed by injection molding according to the standards and methods described in the instructions, and the binding force and PI value were tested. The test results are shown in Table 3.

[0051] In Example 3, the effects of different glass fiber contents and different inorganic minerals on the binding force of NMT and the PI value of LDS activity were investigated. It can be seen from the data in Table 3 that the inorganic minerals used in the experiment can significantly increase the PI value of the polyester composit...

Abstract

The invention provides a polyester composite material capable of being simultaneously applied to an NMT technology and an LDS technology. The polyester composite material comprises the components in percentage by mass: 30-70% of PBT resin, 3-20% of polyolefin, 1-15% of metallic compound, 0.05-0.5% of antioxidant, 0.1-2.0% of mold releasing agent and 10-40% of glass fibre. The polyester composite material capable of being simultaneously applied to the NMT technology and the LDS technology can be applied to the NMT technology and the LDS technology at the same time. A preparation method for the polyester composite material capable of being simultaneously applied to the NMT technology and the LDS technology is also provided, the method is simple and feasible, low in cost and suitable for mass production application.

Description

technical field [0001] The present invention relates to a kind of polyester composite material that can be applied to NMT technology and LDS technology simultaneously, especially relate to a kind of polyester composite material that can be used in nano injection molding (NMT) and laser direct structuring technology (LDS) simultaneously and preparation thereof method. Background technique [0002] In many industrial fields, it is necessary to use the combination design of plastic and metal. The two most common plastic / metal bonding techniques are in-mold injection molding and adhesive bonding. With the increasing demand for metals in the field of consumer electronics, especially mobile phones, tablet computers and notebook computers, there is an urgent need for a more effective plastic / metal bonding technology, which requires higher bonding strength, simpler production processes, and more High design freedom, lighter weight and smaller volume. [0003] Japan's Taisei Corpo...
