In the present solution, by being added by hollow glass micropearl and its 17 fluorine decyl trimethoxy in conventional Silica hydrogel Additive made of base silane, N- aminoethyls -3- aminopropyltriethoxies dimethoxysilane and phthalic anhydride, to keep silicon solidifying The a large amount of silicone hydroxyl of the surface grafting of glue and sepiolite cashmere powder, to make silica gel internal stress reduce, when by local pressure, Its endoparticle percentage of head rice significantly improves, and effectively increases the resistance to pressure of silica gel, keeps its resilience more preferable.
As another preferred embodiment of the present invention, the interior porous ceramics filled of the hard material filled cavity 405 Particle is fired by base-material, filler material and perforating agent, and according to weight ratio, the base-material is by 20-30 parts of calcined kaolins, 34- The mica composition of 38 parts of clay and 16-18 part, work of the filler material by 2-3 part simple substance silica flours, 2-4 parts of fineness no more than 5 microns Property alumina powder and 9-10 parts of modified manometer silicon dioxide composition, perforating agent is by 8-10 part fineness no more than 30 microns of carbon The kyanite fine powder of SiClx fine powder and 2-3 parts of fineness no more than 45 microns forms；The modified manometer silicon dioxide is will be commercially available The surface modifier of nano silicon dioxide and its weight 3-5% is mixed to get, and the surface modifier is by barium hydroxide, sodium bicarbonate With KH550 according to weight ratio 3-4:1-2:30 ratio mixes.
The method for cooking of above-mentioned porous ceramic particles is：Each raw material is chosen first, in accordance with above-mentioned ratio and raw material is carried out Processing, is then sintered after batch mixing, milling in proportion, rapidly cold with the rate of temperature fall of 300-400 DEG C/min after sintering But to after room temperature, the particle that grain size is no more than 0.2cm is crushed to using crusher, it is described processing is carried out to raw material to refer to, The surface modifier of commercially available nano silicon dioxide and its weight 3-5% are mixed to get modified manometer silicon dioxide, which is modified Agent is by barium hydroxide, sodium bicarbonate and KH550 according to weight ratio 3-4:1-2:30 ratio mixes；
The batch mixing, milling refer to the water that each raw material gross weight 35% is added into mixed each raw material successively, each raw material gross weight 2% acetone, each raw material gross weight 1% vegetable oil for industry purpose and each raw material gross weight 0.8% starch, then mix uniformly and the system of grinding At the powder that fineness is 300 mesh.
The sintering is divided into low-temperature zone, middle-temperature section and oxidation and sinter section three parts, wherein low-temperature zone is to instigate in-furnace temperature 420 DEG C are uniformly increased to from room temperature in 6h, and keeps temperature 1-2h, in the process, oxygen content in stove is kept to be not higher than 4%；
The middle-temperature section refers to that in-furnace temperature is made uniformly to be increased to 1050 DEG C in 4h from 420 DEG C, in the process, is kept in stove Oxygen content is not less than 45%；
The oxidation and sinter section refers to so that in-furnace temperature is uniformly increased to 1850 DEG C in 3h from 1050 DEG C, and keep temperature 4h, In the process, oxygen content in stove is kept to be not less than 45%.
In the present solution, using the convenient source calcined kaolin and clay of firing ceramics as base-material, wherein being mixed into carbonization Silicon, aquamaine mountain flour both can ensure that in the ceramics after firing as perforating agent containing some opening stomatas（Or open pore）, Nor its intensity can be influenced；Just because of the presence of these stomatas, it is made to become porous structure, vibrations and punching can be absorbed Hit power；Silicon carbide is easy to happen oxidation reaction generation silica in high temperature oxidative atmosphere and carbon dioxide, the reaction start Temperature is higher, and 1000 DEG C start apparent oxidation, and particle is thinner, then oxidation rate is faster, reaction product CO2Effusion be easy to cause Ceramic body surface formation open pore, and reaction product SiO2With greater activity, mullite is generated with oxidation reactive aluminum, from And mullite reinforcement is formed in ceramics；Meanwhile at high temperature, the kyanite fine powder in perforating agent, both can ensure that generation compared with More mullite phases ensures that the mechanical strength of product, kyanite decompose since 1100 DEG C or so, generate mullite and SiO2, Notable decomposition and inversion after 1300 DEG C, it is also fillable since mullitization reaction is with the volume expansion of 16-18% Due to the hole that Oxidation of SiC generates, single hole is made to become smaller, whole porosity reduces, and can change ceramic inner pore Shape and distribution；Simple substance silica flour in filler material, part oxidation in sintering process form silica and participate in sintering reaction, Melting provides the free system of liquid under another part high temperature, reduces sintering temperature, and convenient for the migration of each structural constituent, knot It closes；
In the present solution, allowing nano level SiO as catalyst using barium hydroxide and sodium bicarbonate mixing2The surface energy of particle The hard to bear effect to hydroxyl increases nanoscale SiO to contain a certain number of oxygen-containing functional groups2The related surface of particle Compatibility, in nanoscale SiO2When particle is sufficiently mixed as filler material and remaining raw material, because of SiO2Particle very little, and compare table Area is big, and the structure of imperceptibility makes rest materials increase with its contact area, makes SiO2Particle can be in material uniformly Dispersion, consequently facilitating SiO2Chemical bonding or physical bond occurs at high temperature with remaining substance.In addition, evenly dispersed receives Meter level SiO2It is equivalent to " anchor point ", the reinforcing matrix generated under hot environment can be made in connection, by external impacts Under effect, the effect of " stress concentration " can be generated so that some surrounding matrixes " surrender " simultaneously absorb more deformation Work(can also generate " pinning-is climbed up and over " effect in addition, increase the crackle resistance suffered in extension, consume work of deformation, from And its toughness is made to increase；And sepiolite cashmere powder is mixed with dodecyl silane coupling agent, titanate coupling agent, nano-titanium dioxide After processing, not only so that the surface nature of sepiolite cashmere powder changes, enable its in sintering with the cordierite of formation, not Carry out stone structure etc. to be combined with each other, further enhances the intensity of agglomerated material.
In addition to this, another preferred embodiment as the present invention, the interior filling of the hard material filled cavity 405 Wheat grain is anticipated, and processing method is：By wheat grain be heated to 70-80 DEG C heat preservation 10min so that its Plumule destroys, and then obtains the lubricant mix of itself and its weight 20-30%, wherein lubricant used is atoleine Oil, bentonite and dimethyl stearyl benzyl ammonium chloride are with 5:2:1 mass ratio is mixed to get.
In the present solution, wheat grain surface can form lubricant layer, in this way when by the powder pinch shock of surrounding, energy Slide displacement is enough generated, to offset the impact force of a part.
