Embodiment 1

[0022] like 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 purged with 100Kpa compressed air to remove excess binder; placed at room temperature at about 25°C for 4 hours, then moved into an oven with a temperature of 120°C, and the fiber bundles are cured for 5 hours.

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 purge to remove excess binder; at room temperature about 25°C, place for 5h, then move into an oven with a temperature of 130°C, and cure the fiber bundles 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 purge to remove excess binder; place at room temperature about 25°C for 5h, then move it into an oven with a temperature of 140°C, and cure the fiber bundles for 3h.

Abstract

The invention relates to a method for preparing ultrafine carbon fiber bundles reinforced by aldehyde resins. The method is characterized by comprising the following steps of stirring, mixing and dissolving liquid at the room temperature, wherein the liquid is prepared by the following raw materials by mass: 10-20 parts of thermosetting resins, 72-85 parts of solvent and 5-8 parts of softener; soaking ultrafine inorganic heat-resistant fiber bundles into the liquid; drying the ultrafine inorganic heat-resistant fiber bundles by means of compressed air of 100Kpa, placing the ultrafine inorganic heat-resistant fiber bundles at the room temperature for 4-6 hours, putting the ultrafine inorganic heat-resistant fiber bundles into a drying oven with the temperature of 120-140 DEG C; curing the ultrafine inorganic heat-resistant fiber bundles for 3-5 hours. By means of the method, requirements for strength of fibers during carrier preparation are met, fiber breakage is avoided, the tensile strength is improved slightly, the flexing resistance index is improved by more than 3-6 times, and the fibers can be used for preparing carrier materials for processing particles. The method has the advantages of being ingenious in design, simple in process, low in cost, easy to implement and the like.

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 vehic...
