Embodiment 1

[0022] like figure 2 As shown, select 10 parts of industrial C5 petroleum resin, add 88 parts of industrial petroleum ether as a solvent, add 2 parts of -25# transformer oil as a softener, stir and dissolve to form a binder liquid; adopt commercially available 1K Soak the carbon fiber bundle as the binder, and then use 100Kpa compressed air to blow off the excess binder; at room temperature about 25°C, first place it for 6h, then move it to an oven at 50°C, and keep it warm for 4h , to complete the fiber bundle curing process.

Embodiment 2

[0024] Select 13 parts of industrial C5 petroleum resin, add 84 parts of industrial petroleum ether as a solvent, add 3 parts of -25# transformer oil as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak Use this as a binder, and then use 100Kpa of compressed air to remove excess binder; place it at room temperature at about 25°C for 7 hours, then move it to an oven at 55°C and keep it warm for 3 hours to complete the curing of the fiber bundle deal with.

Embodiment 3

[0026] Select 15 parts of industrial C9 petroleum resin, add 81 parts of industrial petroleum ether as a solvent, add 4 parts of -25# transformer oil as a softener, stir and dissolve to form a binder liquid; use commercially available 1K carbon fiber bundles, soak Use this as a binder, and then use 100Kpa of compressed air to remove excess binder; place it at room temperature at about 25°C for 8 hours, then move it to an oven at 60°C and keep it warm for 2 hours to complete the curing of the fiber bundle deal with.

Abstract

The invention relates to a method for preparing ultra-fine carbon fiber bundles reinforced by hydrocarbon resins, which is characterized in that the specific steps are as follows: by mass parts, 10-15 parts of thermosetting resin, 81-88 parts of solvent and 2-4 parts of supple After stirring and dissolving, the carbon fiber bundles or ropes are soaked in the binder liquid, and after the excess binder liquid is blown away by air, it is placed at room temperature for 6-8 hours, and then it is heated in an oven at 50-60°C. , and then after 2 ~ 4h curing treatment 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 anti-bending and flexing performance index is increased by more than 3 to 5 times. The fiber is used to prepare the carrier material for particle treatment; The method has the characteristics of ingenious thinking, simple process, low cost, easy realization and the like.

Description

technical field [0001] The invention relates to a preparation method of hydrocarbon resin-reinforced ultrafine carbon fiber bundles, which are used to prepare DOC, POC, CSF and similar DPF particle post-processor carrier materials, and can also be applied to SCR post-processor carrier materials. 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 vehicles, it is mainl...
