Embodiment 1

[0022] Such as figure 2 As shown, select 10 parts of industrial phenolic resin, add 89 parts of industrial alcohol as a solvent, add 5 parts of triethanolamine as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak this as a The binder is then blown with 100Kpa compressed air to remove excess binder; place it at room temperature at about 25°C for 4h, then move it into an oven with a temperature of 120°C, and the fiber bundle is cured for 5h.

Embodiment 2

[0024] Select 15 parts of industrial phenolic resin, add 78 parts of industrial alcohol as a solvent, add 7 parts of triethanolamine as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak this as a binder , and then, use 100Kpa compressed air to blow away excess binder; place at room temperature about 25°C for 5h, then move into an oven with a temperature of 130°C, and the fiber bundles are cured for 4h.

Embodiment 3

[0026] Select 20 parts of industrial phenolic resin, add 75 parts of industrial alcohol as a solvent, add 8 parts of triethanolamine as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak this as a binder , and then, use 100Kpa compressed air to blow away excess binder; place it at room temperature at about 25°C for 5h, then move it into an oven with a temperature of 140°C, and the fiber bundle is cured for 3h.

Abstract

The invention relates to a method for preparing ultrafine carbon fiber bundles strengthened by aldehyde resin, which is characterized in that the specific steps are as follows: 10-20 parts of thermosetting resin, 72-85 parts of solvent and 5-8 parts of supple After the liquid formed by the agent is stirred, mixed and dissolved at room temperature, the ultrafine inorganic heat-resistant fiber bundles are soaked in the liquid, and then dried with 100Kpa compressed air. In the oven, and then after 3~5h curing treatment. It meets the strength requirements of the fiber in the process of preparing the carrier, prevents broken filaments, and slightly increases the tensile strength, but the flex resistance index is increased by more than 3 to 6 times. The fiber is used to prepare the carrier material for particle treatment; it has a clever idea , simple process, low cost, easy to implement and so on.

Description

technical field [0001] The invention relates to a method for preparing ultrafine carbon fiber bundles strengthened by aldehyde resin, which is used for preparing carrier materials of DOC, POC, CSF and similar DPF particle post-processors, and can also be applied to the carrier materials of SCR post-processors. Background technique [0002] For the automotive industry, energy saving and environmental protection are common issues facing the world at present; although the fuel economy of diesel engines is higher than that of gasoline engines, the emission of particulates from diesel engines is 20 to 70 times that of gasoline engines, so the application of diesel engines is subject to certain restrictions. limits; [0003] Vehicle pollutants mainly include NOX and PM; among all particulate matter emissions in the atmosphere, motor vehicle emissions occupy the third place in the total, approaching 600,000 tons per year; [0004] In the particulate matter emission of motor vehicl...
