Embodiment 1

[0022] Such as figure 2 As shown, select 5 parts of industrial C5 petroleum resin, add 85 parts of industrial petroleum ether as a solvent, and 10 parts of -35# diesel oil, stir and dissolve to form a binder liquid; The 1mm basalt fiber rope is soaked as a binder, and then blown with 100Kpa compressed air to remove excess binder; place it at room temperature for 6 hours at about 25°C to complete the curing of the fiber bundle.

Embodiment 2

[0024] Select 8 parts of industrial C5 petroleum resin, add 80 parts of industrial petroleum ether as a solvent, and 12 parts of -35# diesel oil, stir and dissolve to form a binder liquid; the fiber with a diameter of 20 μm is used to prepare a 1 mm diameter Soak the basalt fiber rope as a binder, and then blow it with 100Kpa compressed air to remove the excess binder; place it at room temperature at about 25°C for 8 hours to complete the curing of the fiber bundle.

Embodiment 3

[0026] Select 10 parts of industrial C9 petroleum resin, add 75 parts of industrial petroleum ether as a solvent, and 15 parts of -35# diesel oil, stir and dissolve to form a binder liquid; the fiber with a diameter of 20 μm is used to prepare a 1 mm diameter Soak the basalt fiber rope as a binder, and then blow it with 100Kpa compressed air to remove the excess binder; place it at room temperature at about 25°C for 10 hours to complete the curing of the fiber bundle.

Abstract

The present invention relates to a preparation method of superfine oxygen-containing inorganic fiber bundle reinforced by hydrocarbon resin, which is characterized in that the specific steps are as follows: 5~10 parts of petroleum resin, 75~85 parts of solvent and 10~ A liquid composed of 15 parts of softening agent, using a mixed liquid of thermosetting resin and industrial solvent, soaks the ultrafine inorganic heat-resistant fiber that can be applied to the particulate filter, and then solidifies to meet the strength of the fiber in the process of preparing the carrier Requirements, prevent broken filaments, slightly increase the tensile strength, but increase the flexural and flexural performance indicators by more than 2 to 4 times, the fiber is used to prepare the carrier material for particle treatment; this method has ingenious ideas, simple process, and low cost Inexpensive, easy to implement and so on.

Description

technical field [0001] The present invention relates to a preparation method of superfine oxygen-containing inorganic fiber bundle strengthened by hydrocarbon resin, which is used to prepare DOC, POC, CSF and the carrier material of particle post-processor similar to DPF, and can also be applied to SCR post-processor carrier material. 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 matte...
