Description
Technical Field
The invention relates to the field of tail gas treatment, in particular to modified glass fiber cloth and a preparation method thereof, a solid ammonia storage device and an automobile.
Background
The Selective Catalytic Reduction (SCR) technology is a treatment process for NOx discharged from tail gas of diesel vehicle, i.e. under the action of catalyst, the reducing agent ammonia or urea is sprayed in to reduce NOx in tail gas into N2And H2O, the reaction equation is as follows:
NO+NO2+2NH3→2N2+3H2O；
4NO+O2+4NH3→4N2+6H2O；
2NO2+O2+4NH3→3N2+6H2O。
the SCR technology is widely applied to the post-treatment of the tail gas of the diesel engine, and the generation of particulate matter PM in the diesel engine is controlled by optimizing the oil injection and combustion processes; the nitrogen oxide formed under the oxygen-rich condition outside the machine is subjected to selective catalytic reduction on the nitrogen oxide (NOx) by using vehicle urea (the vehicle urea is decomposed at a certain temperature to generate ammonia) in time, so that the aims of saving energy and reducing emission are fulfilled. In practical application, the reducing agent ammonia in the SCR technology is usually obtained by decomposing a liquid urea aqueous solution, and although the liquid urea aqueous solution has wide sources, the production threshold is low, the quality is uneven, and the problems of coking and nozzle blockage caused by the presence of chemically active substances in the liquid urea aqueous solution during use are easily caused.
The solid ammonia is used for adsorbing and storing ammonia gas in a specific container at normal temperature and releasing the ammonia gas at a specific temperature; solid ammonia is used for replacing liquid urea in SCR, ammonia gas is released to an SCR system under a specific working condition, the requirements of the SCR system are met, the problems of coking and blockage of the SCR system of a vehicle can be solved, and meanwhile, the SCR system has the advantages of being not bad, not working by mistake, not lighting, saving worry, saving trouble and the like.
However, in the conventional ammonia charging process, the solid ammonia storage material reacts violently with ammonia gas to form strontium ammine chloride solid with high hardness, and the strontium ammine chloride solid formed by preferential reaction at the inlet of the tank body can prevent the unreacted solid ammonia storage material from contacting with the ammonia gas to react, thereby preventing the whole ammonia tank from uniformly and rapidly charging ammonia.
Disclosure of Invention
Based on the technical scheme, the invention provides the modified glass fiber cloth, the preparation method thereof, the solid ammonia storage device and the automobile.

According to the preparation method of the modified glass fiber cloth, the glass fiber base cloth is dipped and pulled in the suspension containing the graphite, the carbon black, the inorganic micro powder, the organic resin, the alcohol and the water in specific parts, wherein the carbon black and the graphite particles are combined to form continuous heat conducting particles by adding the graphite and the carbon black, so that the heat conducting property of the modified glass fiber cloth is effectively improved; the modified glass fiber fabric is further added with specific inorganic micro powder, has good phase adsorption performance with glass fiber base fabric, adopts specific organic resin, has good infiltration effect under the action of ethanol and water, has good compatibility with graphite, carbon black and inorganic particles, enables the graphite, the carbon black and the inorganic particles to permeate into the glass fiber base fabric, controls the proportion among the components, constructs a heat conduction system with stable structures of the graphite, the carbon black and the inorganic particles, and effectively improves the overall bonding performance and the heat conduction performance of the modified glass fiber fabric.
It can be understood that the number of pulling times may be one or more, preferably 3 to 4 pulling times.
It can be understood that the glass fiber base cloth of the modified glass fiber cloth provided by the invention is provided with holes. When preparing the modified glass fiber cloth into a bag for filling solid ammonia storage materials and then filling ammonia, the bag made of the modified glass fiber cloth can expand to 1-1.5 times, the cloth-shaped holes of the glass fiber base cloth can be further stretched, gas permeation is facilitated, and the part which is locally contacted with stainless steel cannot influence heat exchange due to the existence of the bag. It can also be understood that the surface modification layers are formed on the inner surface and the outer surface of the modified glass fiber cloth provided by the invention.
In some examples, in the preparation method of the modified glass fiber cloth, the suspension comprises the following components in parts by mass:
by controlling the adding proportion of the inorganic micro powder, the stability of the suspension is better on the premise of not reducing the heat-conducting property; if the proportion of the inorganic micro powder is too large, the suspension is unstable, the turbid liquid is quickly layered, and the construction effect is poor.
In some of these examples, the inorganic micropowder is selected from the group consisting of magnesium oxide micropowder. It can be understood that when the inorganic micropowder selects the magnesium oxide micropowder, the heat conducting property of the modified glass fiber cloth is better, but the inorganic micropowder selects the aluminum oxide micropowder possibly more suitably in consideration of cost reasons.
In some examples, in the preparation method of the modified glass fiber cloth, the mass ratio of the inorganic micro powder to the graphite is (0.1-0.8): 1; optionally, the mass ratio of the inorganic micro powder to the graphite is (0.1-0.5): 1; preferably, the mass ratio of the inorganic micro powder to the graphite is 0.1: 1.
By controlling the mass ratio between the graphite and the inorganic powder, the construction stability of the turbid liquid can be improved on the premise of reducing the heat conductivity.
Preferably, the suspension comprises the following components in parts by mass:
in some examples, the modified glass fiber cloth is prepared by a method in which the fibers are selected from glass fiber filter cotton or glass fiber mesh cloth. It can be understood that the glass fiber filter cotton and the glass fiber mesh cloth have certain strength and toughness, can resist the use temperature of about 300 ℃, can be elongated and keep continuous without breaking at a certain temperature, and the bag made of the material can be expanded and enlarged in the ammonia filling process, so that the bag is stretched into a porous net-shaped structure. After dip coating with a material that improves thermal conductivity, the heat transfer rate between the walls of the bag and the metal housing can be improved.
In some examples, the modified glass fiber cloth is prepared by a method in which the phenolic resin is at least one selected from the group consisting of technical grade formaldehyde tert-butyl phenol, formaldehyde p-phenyl phenol and formaldehyde p-tert-octyl phenol; alternatively, the phenolic resin is formaldehyde tert-butyl phenol.

The inventor finds that in the preparation method of the modified glass fiber cloth, the modified glass fiber cloth prepared when the organic resin is selected from polyimide, acrylic acid, polyester resin and epoxy resin cannot meet the requirement of a 300 ℃ temperature environment in a solid ammonia storage device and can be carbonized.
In some examples, the modified glass fiber cloth is prepared by a method in which the D50 of the graphite is 50-300 μm; optionally, the graphite has a D50 of 100 to 200 μm.
In some examples, the modified glass fiber cloth is prepared by a method in which the carbon black has a D50 ≦ 70 μm.
It can be understood that the smaller the particle size of the carbon black is, the more favorable the thermal conductivity of the modified glass fiber cloth is; considering cost reasons, the D50 of the carbon black is less than or equal to 70 mu m; alternatively, the carbon black has a D50 ≦ 50 μm; preferably, the carbon black has a D50 of 10 to 39 μm.
In some examples, in the preparation method of the modified glass fiber cloth, the D50 of the inorganic micropowder is 0.1-100 μm; optionally, the D50 of the inorganic micropowder is 0.1-10 μm; preferably, the D50 of the inorganic fine powder is 0.6 to 10 μm.
The particle sizes of the graphite, the carbon black and the inorganic micro powder are controlled, so that the graphite, the carbon black and the inorganic micro powder can form a continuous heat conducting microstructure, and the heat transfer of the modified glass fiber cloth is guaranteed.
In some examples, in the method for preparing the modified glass fiber cloth, the alcohol is selected from at least one of methanol, ethanol and propanol; preferably, the alcohol is ethanol.
In some examples, the preparation method of the modified glass fiber cloth comprises the following steps:
mixing graphite, carbon black, inorganic micropowder, organic resin, alcohol and water.
In some of these examples, the suspension is prepared by mixing graphite, carbon black, inorganic fine powder, organic resin, alcohol and water and then ball milling.

It can be understood that after the modified glass fiber cloth is taken out by dipping, pulling and pulling, the excess liquid on the surface is blown, which is beneficial to uniform coating. In some of these examples, the surface may be purged with compressed air to remove liquid from the surface.
In some examples, the method for preparing the modified glass fiber cloth further comprises a step of extruding the impregnated glass fiber base cloth after the impregnation step and before the heat treatment step. Therefore, the suspension containing graphite, carbon black and inorganic particles can be further ensured to permeate into the glass fiber base cloth, and the glass fiber base cloth cannot fall off after heat treatment.
In some examples, in the preparation method of the modified glass fiber cloth, the heat treatment is: curing for 5-10 min at 100-120 deg.c.
In some specific examples, the heat treatment in the preparation of the suspension is: curing at 110 deg.C for 8 min.
In some examples, the mass of the graphite in the modified glass fiber cloth accounts for 3% -9% of the total mass of the modified glass fiber cloth. Therefore, the method is beneficial to improving the heat conductivity and can avoid falling off caused by too thick coating.
The invention provides a glass fiber cloth bag, which is made of modified glass fiber cloth prepared by the preparation method of the modified glass fiber cloth or the modified glass fiber cloth.
