Detailed Description
The disclosure may be understood more readily by reference to the following detailed description of preferred embodiments of the invention and the examples included therein. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, including definitions, will control.
The term "prepared from …" as used herein is synonymous with "comprising". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
The conjunction "consisting of …" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of …" appears in a clause of the subject matter of the claims rather than immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.
When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when a range of "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.
The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. "optional" or "any" means that the subsequently described event or events may or may not occur, and that the description includes instances where the event occurs and instances where it does not.
Approximating language, as used herein throughout the specification and claims, is intended to modify a quantity, such that the invention is not limited to the specific quantity, but includes portions that are literally received for modification without substantial change in the basic function to which the invention is related. Accordingly, the use of "about" to modify a numerical value means that the invention is not limited to the precise value. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. In the present description and claims, range limitations may be combined and/or interchanged, including all sub-ranges contained therein if not otherwise stated.
In addition, the indefinite articles "a" and "an" preceding an element or component of the invention are not intended to limit the number requirement (i.e., the number of occurrences) of the element or component. Thus, "a" or "an" should be read to include one or at least one, and the singular form of an element or component also includes the plural unless the stated number clearly indicates that the singular form is intended.
"Polymer" means a polymeric compound prepared by polymerizing monomers of the same or different types. The generic term "polymer" embraces the terms "homopolymer", "copolymer", "terpolymer" and "interpolymer". By "interpolymer" is meant a polymer prepared by polymerizing at least two different monomers. The generic term "interpolymer" includes the term "copolymer" (which is generally used to refer to polymers prepared from two different monomers) and the term "terpolymer" (which is generally used to refer to polymers prepared from three different monomers). It also includes polymers made by polymerizing more monomers. "blend" means a polymer formed by two or more polymers being mixed together by physical or chemical means.
In order to solve the above problems, a first aspect of the present invention provides a method for preparing an air filter material for an automobile roof, which comprises the following specific steps:
s1, preparing an activated carbon non-woven fabric;
s2, stacking the activated carbon non-woven fabric and the glass fiber felt, forming, cooling and cutting to obtain a finished product.
In some preferred embodiments, in the S1 step, activated carbon is supported on the nonwoven fabric by a dip coating method, pressed by a roller, and dried to obtain the activated carbon nonwoven fabric.
In some preferred embodiments, the number of press rolls in the S1 step is 1 to 4.
The compression roller can make active carbon effectively load in the non-woven fabrics, and the control of compression roller number of times and environmental parameter has great influence to the evenly distributed of year charcoal volume and active carbon in the non-woven fabrics. The compression roller can effectively guarantee active carbon evenly distributed in non-woven fabrics fiber line, but causes the active carbon to drop easily when the compression roller number of times is too high on the one hand, and on the other hand makes the adhesive permeate to the active carbon structure easily, influences the adsorption efficiency of active carbon. According to the invention, a large number of experiments prove that the number of times of pressing the roller in the step S1 is 1-4; when the temperature of the roller is 20-30 ℃ and the relative humidity is 50-60%, the activated carbon is attached to the non-woven fabric to the maximum extent under the action of the specific adhesive, the porosity of the material is good, and the capacity of the activated carbon non-woven fabric for adsorbing harmful gases of benzene series in the automobile is high.
In some preferred embodiments, the dip coating method is performed using a dip solution, wherein the raw materials of the dip solution comprise, by weight percentage, 15-30% of activated carbon, 5-15% of a binder, 0.1-1% of a finishing agent, and the balance of water.
More preferably, the raw materials of the impregnation liquid comprise, by weight, 18-22% of activated carbon, 7-12% of a binder, 0.2-0.8% of a finishing agent, and the balance of water.
In some preferred embodiments, the particle size of the activated carbon is from 48um to 71 um.
In some preferred embodiments, the preparation method of the impregnation fluid comprises: adding the finishing agent into water, heating and stirring, adding activated carbon, stirring uniformly, adding the binder, and stirring for 5-15min to obtain the impregnation liquid.
The active carbon has strong adsorption capacity and stable physical and chemical properties, and is widely applied in various fields. The invention adopts the combination of the activated carbon and the non-woven fabric material, thereby improving the capability of the filter material for purifying the air in the vehicle. In the actual production process of preparing the activated carbon non-woven fabric, the activated carbon is found to have a developed void structure and a large specific surface area, and a binder easily enters a porous structure in the process of preparing the impregnation liquid, so that the adsorption capacity of the activated carbon non-woven fabric is greatly influenced. A large number of experiments are researched and found, when the impregnation liquid is prepared, the activated carbon is firstly added into water of the surfactant and the auxiliary agent, the porous structure of the activated carbon is filled with water through stirring, then the binder is added, so that the binder cannot easily enter the porous structure of the activated carbon and is coated on the surface of activated carbon particles, the porous structure is not blocked, meanwhile, the binder is favorable for the combination between the activated carbon and non-woven fabric fibers, and is also favorable for steam to escape from the porous structure of the activated carbon in the drying process, the loss of the porous structure of the activated carbon is inhibited, and the carbon carrying amount and the adsorption capacity of the activated carbon non-woven fabric are simultaneously improved.
In some preferred embodiments, in the S2 step, the activated carbon non-woven fabric and the glass fiber mat are stacked and then shaped by using a hot press.
In some preferred embodiments, in the step S2, the hot press is preheated when the hot press is used for shaping, and shaping is performed after the temperature is stable.
The invention further discovers that when the hot press is used for shaping and compounding the stacked glass fiber and the activated carbon non-woven fabric, the hot press is preheated in advance, and after the preset temperature is reached, the glass fiber-non-woven fabric material is put into the hot press for hot press shaping, so that the falling of the activated carbon in the non-woven fabric can be effectively inhibited, and the distribution of the activated carbon in the air filter material is more uniform than that of the activated carbon in the air filter material by direct hot press shaping.
In some preferred embodiments, in the step S2, the setting temperature of the hot press is 130-155 ℃, the setting pressure is 1-3MPa, and the setting time is 2-5 min.
Further preferably, in the step S2, the setting temperature of the hot press is 145-150 ℃, the setting pressure is 1.5-2.5MPa, and the setting time is 2.5-4 min.
In the process of actually producing the air filtering material, the control of process parameters during compounding of the glass fiber and the activated carbon non-woven fabric has important influence on the performance of a finished product, and the adjustment of temperature, pressure and setting time directly influences the adsorption capacity of the activated carbon non-woven fabric and the binding capacity of the activated carbon non-woven fabric and the glass fiber. The adhesive can be quickly melted under the conditions of specific temperature and pressure to form an adhesive layer with moderate fluidity, the temperature and the pressure are not easy to be too low or too high, the production efficiency is low when the temperature is too low, and the fluidity of the adhesive is too high when the temperature is too high, so that the adhesive easily flows into the porous structure of the activated carbon to influence the adsorption capacity of the activated carbon non-woven fabric; when the pressure is too low, the adhesion between the activated carbon non-woven fabric and the glass fiber mat is poor, and when the pressure is too high, the structure of the activated carbon is damaged. A great deal of experimental researches show that when the setting temperature of the hot press is 130-.
In some preferred embodiments, the nonwoven fabric is a chemical nonwoven fabric; the thickness of the chemical non-woven fabric is 0.04-0.2 mm.
More preferably, the chemical nonwoven fabric has a thickness of 0.1 mm.
In some preferred embodiments, the binder comprises at least one of polyvinyl acetate, epoxy resin, polyacrylic emulsion, hydroxymethyl cellulose.
In some preferred embodiments, the finishing agent comprises at least one of polyvinyl alcohol, C10-18 alkyl sulfate, liquid paraffin, glyceryl stearate, metal soap.
Further preferably, the finish comprises polyvinyl alcohol and a C10-18 alkyl sulfate.
The activated carbon is composed of fine graphite-like crystallites and hydrocarbons connecting them together, and has a strong adsorption capacity for many harmful substances. When a high-performance adsorption non-woven fabric is developed, the selection of the activated carbon, the binder and the non-woven fabric is the key for improving the adsorption performance, because the air filtering material not only requires that the binder has better adhesive capacity, but also requires that the influence of the binder on the adsorption capacity of the activated carbon is smaller and better when the activated carbon and the binder are prepared into a colloidal carbon mixture, and the smooth composite molding of the activated carbon non-woven fabric and a glass fiber mat is ensured. According to the invention, a large number of experiments are carried out to find that the particle size of the activated carbon can not be too large or too small to ensure that the activated carbon can be uniformly distributed on the carrier, the particle size of the activated carbon is favorable for uniform distribution when the particle size of the activated carbon is small, but the particles are easy to agglomerate among superfine particles with too small particle size to form a particle body with increased particle size, so that the integral dispersion effect of the activated carbon is influenced, and the distribution uniformity and the adsorption capacity of the non-woven fabric are further influenced. Through a large number of tests, the combination of the activated carbon and the non-woven fabric is most uniform when the particle size range of the activated carbon particles is 48-71 um; meanwhile, the vinyl acetate adhesive is selected as the adhesive, so that the loading capacity of the activated carbon can be balanced to a large extent, the non-woven fabric is kept fluffy and soft, the air permeability is good, the processing resistance is small, the material is non-toxic, harmless and odorless, and the adhesive is compounded with the chopped strand mat for the specific automobile roof in the next step. According to the invention, a large number of experiments are researched and found that the types of the non-woven fabrics obtained by different production processes have great influence on the uniformity of the activated carbon in the base fabric, and when the non-woven fabrics are chemically bonded, the non-woven fabrics can be fused and bonded with the polymer binder with similar structure due to the addition of the non-toxic and harmless polymer binder in the production process, so that the high-specific-surface-area material is loaded to a great extent. The non-woven fabric modified by the substances has higher adsorption capacity on pollutants in an automobile and strong binding capacity with a glass fiber felt.
The invention provides an application of a preparation method of an air filtering material for an automobile ceiling, which is applied to removal of harmful substances in an automobile and optimization of air quality.
