The compound generates less heat during the burning stage of honeycomb ceramics, thereby reducing the reject rate of the honeycomb ceramics. Moreover, the compound is characterized in that: the compound comprises foaming resin powder, wherein the diameter of foaming resin granule is 0.1 micron to 30 micron; the weight of foaming resin occupies 0.4 to 17 percent of that of the inorganic matters in the entire compound.
Description
Technical field
The invention belongs to the ceramic honey comb manufacturing technology, particularly possess the ceramic honey comb manufacturing technology of certain pore size and void content.
Background technology
Need to comprise that pore-forming material forms pore in ceramic honey comb in the feedstock composition that when the preparation high porosity particle trap honeycomb ceramic, adopts.Normal at present employing spherical graphite and/or flour are as pore-forming material.There are the following problems at present as pore-forming material to adopt graphite or flour, and promptly these two kinds of materials quantity of heat production under hot conditions own is big, and this just causes ceramic honey comb in the stage of burning till the rimose phenomenon to take place easily, has directly reduced the yield rate of ceramic honey comb.
Summary of the invention
The purpose of this invention is to provide a kind of composition for preparing high porosity particle trap honeycomb ceramic, it is few that said composition is burnt till the stage heat production at ceramic honey comb, reduced the scrap rate of ceramic honey comb.
Technological thought of the present invention is to have utilized the characteristic of foamex to solve the high problem of ceramic honey comb scrap rate.
Technical scheme of the present invention is as follows:
The composition of preparation high porosity particle trap honeycomb ceramic comprises the foamex powder, described foamex particulate diameter is the 0.1-30 micron, and the weight of described foamex accounts for the 0.4-17% of the powder composition weight of whole preparation high porosity particle trap honeycomb ceramics.
Described foamex is the acrylic acid foamex.
Described foamex also can be the polyolefin resin-oatmeal.
The composition of preparation high porosity particle trap honeycomb ceramic also comprises graphite except that comprising above-mentioned foamex, the weight of graphite accounts for the 0.8-20% of the powder composition weight of whole preparation high porosity particle trap honeycomb ceramics.
The composition of preparation high porosity particle trap honeycomb ceramic also comprises flour except that comprising above-mentioned foamex, the weight of flour accounts for the 0.4-17% of the powder composition weight of whole preparation high porosity particle trap honeycomb ceramics.
The composition of preparation high porosity particle trap honeycomb ceramic also comprises flour except that comprising above-mentioned foamex, graphite, the weight of flour accounts for the 0.3-17% of the powder composition weight of whole preparation high porosity particle trap honeycomb ceramics.
Technique effect of the present invention:
Because the foamex particle is the spherical particle of intermediate hollow, so combustible solids content is low, therefore graphite and the flour of replacing in the composition for preparing high porosity particle trap honeycomb ceramic with foamex burns till the less calories that the stage foamex discharges as pore-forming material at ceramic honey comb, thereby greatly reduce ceramic honey comb rimose risk, improved yield rate.
Foamex particle solid matter under firing temperature is burnouted, foamex possesses certain intensity simultaneously, can keep out mechanical force extraneous in the ceramic honey comb moulding process foamex particulate is destroyed, therefore form the pore close with particle size through burning till this ceramic honey comb position, particle place of processing.The present invention limit foamex particulate size can make the inner pore that forms the corresponding size size of ceramic honey comb like this pore of size help adsorbing and be filtered that particulate matter can not stop passing through of gas again in the gas.
The acrylic acid foamex particulate physical strength height that the present invention adopts, it is strong promptly to tolerate the external force ability, and particle is difficult for destroyed, and this helps controlling the pore size distribution and the void content of pore in the final ceramic honey comb.
In addition, the acrylic acid foamex particle that the present invention adopts is little, intensity is high, add it to can play lubricant in the composition for preparing high porosity particle trap honeycomb ceramic effect, can improve the processability of pug greatly at preparation ceramic honey comb pug.
With foamex partly replace the preparation high porosity particle trap honeycomb ceramic composition in graphite and flour, promptly keep the cost that a certain proportion of graphite and flour component can reduce the composition of preparation high porosity particle trap honeycomb ceramic, also have the above-mentioned technique effect of the present invention simultaneously.
