Abstract

The invention belongs to a filter which is based on a bamboo base material and is used for capturing diesel vehicle exhaust gas emission particulate matters. The preparation technology of the filter is characterized by comprising the following steps of: making raw bamboos into bamboo filaments, selecting the bamboo filaments with the thickness in the rang from 0.05mm to 1m and the width in the range from 1m to 10mm, placing glass fibers onto which mixed glue is sprayed and the bamboo filaments in a mold to be set according to a proportion of 1: 5, and after setting, drying for 20-30 minutes; soaking the filter in a saturated KOH solution for 18-24 hours, then carrying out acid pickling for 3 hours by using 0.1mol / L of HCL (Hydrochloric Acid), rinsing for 1 hour with clear water, and drying the rinsed filter at 120 DEG C till the mass is constant; and placing the filter in a saturated phosphorus based frame retardant, soaking for 3 hours, then soaking the filter in a urea solution for 18-24 hours, and drying to obtain the filter based on the bamboo base material.

Description

technical field [0001] The invention relates to a filter body and a preparation process thereof, in particular to a bamboo filter body and a preparation process thereof, which is mainly based on a bamboo base material and is a filter body for trapping particulate matter emitted from diesel vehicle exhaust. Background technique [0002] Due to its good economy and power, diesel engines have been more and more widely used in motor vehicles in recent years. However, diesel vehicles emit a large amount of particulates and nitrogen oxides during use. The main component of particles is carbon. Due to its small particle size, it can be suspended in the air for a long time, seriously pollutes the environment, and has a strong carcinogenic effect on the human body. Therefore, many countries in the world have successively enacted laws and regulations to limit the particulate emission of diesel vehicles. Europe and the United States have implemented strict Euro V and EPA2010 emis...
