Description
Technical field
The present invention relates to a kind of wearing composite material ceramic embedded on rubber matrix and preparation method thereof, belong to technical field of composite materials.
Background technique
In industries such as metallurgy, electric power, building materials, machinery, chemical industry, abrasive rubber and pottery often are used to make wear parts, like abrasion-proof backing block, conveyor belt, pipeline etc.The elastic strain of rubber material is big, and Young's modulus is minimum; The Poisson's ratio of rubber is big, and volume is almost constant during deformation.Rubber not only is widely used in the manufacturing of vehicle tyre, and is used for the manufacturing of device wear parts such as bunker, funnel, chute.Application number is 93111075.0 Chinese invention patent " super wearproof rubber liner for cold burden and production method "; With natural rubber, SBR and butadiene rubber is sizing material; Selecting an amount of activator, promoter, tenderer, aging agent, vulcanzing agent, plasticizing agent, reinforcing agent and reinforcing filler for use is compounding ingredient, has produced abrasion-proof backing block by rational prescription and charging sequence, manufacturing process.Application number is 94211291.1 Chinese utility model patent " a kind of conveyor belt ", in rubber, is provided with the wire netting skeleton, and the main effect of this wire netting skeleton is to guarantee that conveyor belt is indeformable under 300 ℃ of high temperature, does not rupture.Application number is 200710179841.3 Chinese invention patents " a kind of preparation methods of wear-resisting rubber composite material "; Adopt graphite modified technology; Invent graphite/rubber composite, prepared the rubber composite of excellent performance, low coefficient of friction, high wear resistance.The rubber wear-resisting liner plate has advantages such as low, in light weight, the easy installation, maintenance convenience of cost, life-span length, toughness and plasticity are good, shock-resistant.
Stupalith has high tenacity, high hardness, advantage such as high temperature resistant, wear-resisting, corrosion-resistant, anti-oxidant, and above-mentioned performance is far superior to macromolecular materials such as metallic material and rubber.But fragility is a deadly defect of stupalith.Therefore, stupalith only is suitable for the little operating mode of impulsive load.Like Chinese utility model patent ZL03207616.9 " welding type wear-resistant ceramic sheet "; Its ceramic plate is made through high-temperature firing technology by alumina powder; Be provided with 1～2 conical welding hole at the middle part of ceramic plate, adopt plug welding technology to be connected on the wear member, some are connected to form integral body.This patent has solved ceramic plate has been pasted on the abrading section, the problem that comes off easily in the use.
Stupalith and other materials is compound, process composite material, big to overcome stupalith fragility, not impact-resistant defective.The Chinese invention patent of application number 200910015174.4 " a kind of metal ceramic composite wear-resistant material and preparation method thereof "; Adopt the wear-resistant ceramic piece of special construction design; Utilize welding technique that wear-resistant ceramic piece and metallic matrix are coupled together, process metal ceramic composite wear-resistant material.The Chinese invention patent of application number 200910016354.4 " in the metal ceramic embedded high-abrasive material and preparation method thereof "; The structure particular design of wear-resistant ceramic piece becomes active section, positioning section; Adopt bonding or hot charging is technological is connected with metal substrate, process high-abrasive material ceramic embedded in the metal.Metal and Ceramic Composite have improved ceramic impact resistance, but under the bigger operating mode of the impact momentum of load, because the deformability of flow of metal is poor, cause the one-tenth piece of stupalith to come off easily.And the weight of metal pottery is big, and the weight of the ceramic-metal composite of processing makes that also much larger than stupalith installation is very not convenient.Application number is that 93233642.6 Chinese utility model patent " wear-resistant ceramic rubber lining " has proposed ceramic top plate and rubber layer base plate through the bonding technology of processing abrasion-proof backing block of adhesive-layer; As the ceramic top plate of wear-resisting working lining because in the buffering that does not laterally have rubber; Under impact loading, become piece to come off easily.Application number be 95247096.9 Chinese utility model patent " ceramic-rubber composite liner " then be with ceramic block, rubber plate, sheet metal through bonding hot vulcanization to together; With application number be that 93233642.6 Chinese utility model patent is similar easily under impact loading, become piece to come off.Application number is that 01276122.2 Chinese utility model patent " ceramic rubber wear-resisting composite sheet ", application number are that 92107080.2 utility model patents " a kind of wear-resistant ceramic rubber lining ", application number are 200820059180.0 utility model patents " a kind of wear-resistant ceramic rubber lining ", all are that ceramic block is bonded on the rubber covering, rather than pottery is embedded rubber inside.
Process composite material by rubber and pottery, it is big to have made full use of the rubber elasticity distortion, can absorb the energy of impulsive load, the percussion of slowing down material, and also the high wear resistance of pottery will prolong the working life of wearing piece greatly.The light weight of rubber, rubber and ceramic composite total quality are convenient to install also less than the composite material of metal with pottery, particularly on-the-spot installation and maintenance.But rubber is not so good as metal and ceramic composite material with the resistance to heat of the composite material of pottery.
Along with the harshness day by day of component of machine applying working condition, particularly the material drop is big, and impact momentum is big, and the wearing and tearing of wearing piece are quite serious; The equipment that some resembles conveying material etc. requires the light weight of wearing piece, and wearing piece is installed easily.Therefore, the user is also relatively more urgent to the demand of the wearing piece of anti-thump, high abrasion, light weight.
Summary of the invention
Not as stupalith, but its toughness, plasticity are good based on existing abrasive rubber antiwear property, and proportion is little, and deformability is strong, can absorb big impact momentum; Stupalith fragility is big, and shock resistance is poor, but it has high wear-resistant characteristics.The present invention provides wearing composite material ceramic embedded in a kind of rubber and preparation method thereof.Utilized two kinds of materials advantage separately, both had high wear-resistant, resisting strong impact, can absorb the advantage of large impact momentum again through distortion.
