Problems solved by technology
[0004] However, the dielectric loss coefficient of ABS resin is 0.004 (23°, 1MHZ), and the high-frequency welding performance is poor, which leads to the direct peeling off of the sun visor frame and skin coating, which seriously restricts the application of ABS resin on the car sun visor frame.

Embodiment 1-3 and comparative example 1-5
[0023] The high-frequency welding ABS composite material for the preparation of automobile sun visors is prepared, and the formula by weight is shown in Table 1.
[0024] Table 1 Formulations of Examples 1-3 and Comparative Examples 1-5
[0025]
[0026] The preparation methods of the above-mentioned high-frequency welding ABS composite materials for automobile sun visors are all the same, including the following steps: premixing a toughening agent, a heat stabilizer, a plasticizer, an antioxidant, and a lubricant in a high-speed mixer for 8- 10min to obtain Mixture 1; Mix ABS resin and polyvinylidene fluoride to obtain Mixture 2;
[0027] The mixture 1 is weighed and weighed 1, and the mixture 2 is weighed and added to the twin-screw extruder for melting, kneading, and extrusion to obtain high-frequency welded ABS composite materials for automotive sun visors. Among them, the twin-screw extruder The processing speed is 350-400r / min, and the extrusion temperature is 160-18...

The invention discloses a high-frequency welding ABS composite material for an automobile sun shield. The high-frequency welding ABS composite material comprises, by weight, 90 parts of ABS resin, 5-10 parts of polyvinylidene fluoride, 3-8 parts of a toughening agent, 0.5-5 parts of a heat stabilizer, 0.5-5 parts of a plasticizer, 0.3-1 part of an antioxidant and 0.5-2 parts of a lubricant. The invention further discloses a preparation method of the high-frequency welding ABS composite material for the automobile sun shield. The polyvinylidene fluoride and ABS resin alloy are adopted, and somepolar groups are added, so that the high-frequency welding capacity of the material is greatly improved, the production process is simple, the cost is low, and the material can be used for the automobile sun visor.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-frequency welded ABS composite material for automobile sun visors and a preparation method thereof. Background technique [0002] At present, cars have become more and more important means of transportation in human work and life. No matter what kind of vehicle model, sun visors are indispensable as an important safety component to protect the driver's eyesight; with the rapid development of the automobile industry, the demand for sun visors is increasing The bigger the size; the sun visors currently on the market are generally made of two materials: 1. Foamed skeleton + skin coating; foamed products cause serious environmental pollution in the production process, and at the same time, the environmental protection performance of foaming raw materials is low, which will affect the long-term use. People's health; on the other hand, foam materials have low flame ret...
