Embodiment 1

[0028] This embodiment provides a high-strength hydrolysis-resistant nylon hubless fan material, which consists of the following components by mass percentage:

[0029]

[0030] The preparation method is as follows:

[0031] (1) Add a silane coupling agent to the nylon base material containing additives according to 1% of the base material mass for coupling treatment, and send it to an electronic weight loss scale;

[0032] (2) the toughening compatibilizer is sent into another electronic weight loss scale and the nylon base material after the coupling treatment is blanked respectively in a ratio of 5%:95%, and glass fiber (including Alkali-free glass fiber and non-alkali hydroalcolysis-resistant glass fiber) blending extrusion granulation,

[0033] The rotational speed of the twin-screw machine is 300 rpm, and the temperature is 235° C., thereby obtaining a high-strength hydrolysis-resistant nylon hubless fan material.

Abstract

The invention relates to a high-strength hydrolysis-resistant nylon wheel hub-free fan material which is prepared from the following components in percentage by weight: medium and high viscosity PA6,a toughening compatilizer, alkali-free glass fibers, alkali-free waterproof alcoholysis glass fibers, a primary antioxidant, an auxiliary antioxidant, a lubricant, hydrolysis-resistant masterbatch andan anti-floating fiber agent. In an equipment process aspect, automatic burdening and metering is adopted, double electronic weight-losing scales are used to unload, and the toughening compatilizer and nylon base materials of various auxiliaries are unloaded in different two scales, so that the blending and prilling are uniform and stable; in a same formula condition, the material has a better performance quality compared with the material adopting conventional manual metering and unloading; secondly, the key point is in the formula aspect, coupling treatment of surface of the nylon base material and formation of a silicon protective film are matched with alkali-free waterproof alcoholysis glass fibers, so that the material has a certain hydrolysis-resistant and a performance index whichis 20% over that of a common nylon fan, so that the performance demand on high performance strength hub-free fan is met.

Description

technical field [0001] The invention belongs to the field of automobile parts, in particular to a high-strength hydrolysis-resistant nylon hubless fan material and a preparation method thereof. Background technique [0002] In recent years, my country's automobile industry has developed vigorously and has become a major country in global automobile production and sales. With the shortage of oil resources and rising oil prices, automobile lightweight has become a major issue in the development of the automobile industry, and the application of engineering plastics is an inevitable choice for automobile lightweight. The degree of plasticization of automobiles shows the manufacturing level of the industry. The interior and exterior parts of foreign cars all use plastic parts. The plastic used in automobiles exceeds 160 kg / vehicle. In recent years, the development and application of non-metallic structural parts has been vigorously promoted. Compared with metals, engineering p...
