Abstract
The invention discloses a kind of binding agent, including component A, B component and Ludox, component A is by the parts by weight of MTMS 20 60, the parts by weight of dimethyldimethoxysil,ne 10 40, the parts by weight of esters solvent 3 12, the parts by weight of butyl glycol ether 0.1 3, the parts by weight of ester plasticizer 5 15 and the parts by weight of methanol 2 10 composition；B component is by the parts by weight of MTMS 45 75, the parts by weight of dimethyldimethoxysil,ne 10 40, the parts by weight of crosslinking agent 0.5 5, the parts by weight of methanol 16 and the parts by weight of solvent 17 composition；The component A：B component：The weight ratio of Ludox is 0.01 0.3:0.5‑1.5:1.The invention provides the preparation method of the binding agent, and molding bonded of the catalyst on board-like, honeycomb fashion and corrugated plate dst catalyst carrier is used it for, the catalytic efficiency of catalyst is not influenceed.
Description
Technical field
The present invention relates to binding agent field, and in particular to a kind of powder Catalyst molding adhesive and prepare
Application in preformed catalyst.
Background technology
Nitrogen oxides (NOx) and VOC (VOCs) be all atmosphere pollution, to environmental and human health impacts
There is very big harm.Administering NOxIn technology, ammine selectivity catalytic reduction (SCR) technology is obtained with the denitration performance of its high efficient and reliable
To being widely applied, the core of this technology is denitrating catalyst.There are two classes at present for VOCs processing：One class is back
The treatment technology such as adsorbent absorption process etc. for the property received；Another kind of is destructive treatment technology such as combustion method, catalytic oxidation
Deng, and catalyst is catalytic oxidation degraded VOCs key.
By taking SCR catalyst as an example, the SCR denitration preformed catalyst generally used in the market has three kinds of structure types：
Honeycomb fashion, board-like and corrugated plate dst.Conventional cellular catalyst is by carrier (mainly TiO2) pressed with active component and auxiliary agent
According to certain proportioning mixing, pressurization is extruded and is cut into cellular unit, is finally assembled into the class monoblock type catalysis of standard module
Agent, although such catalyst small volume cost is higher, reaches if can directly load to catalyst on formed honeycomb ceramics
Denitration cost will be substantially reduced to preferable denitration effect；Board-like catalyst and corrugated plate dst catalyst is required for work
Property component be fixed on carrier, simply the carrier of board-like catalyst be metallic framework, corrugated plating catalyst carrier be glass fibers
Dimension, while corrugated plating catalyst also has a feature, exactly needs with binding agent that smooth glass fibre extruding is corrugated
Shape, the step for shaping on corrugated plating catalyst and performance have vital influence.
In summary, catalyst is fixed on shaping carrier, the selection of binding agent is very crucial.
CN102941127A patent prospectus disclose a kind of SCR plate-type denitration catalysts special molding agent and
Its application method, the forming agent is by polyvinyl alcohol, organic binder bond, kaolin, glass powder with low melting point and Chemical Felter group
Into wherein organic binder bond is the mixture of methylcellulose or hydroxypropyl methyl cellulose or both, and Chemical Felter is
Ludox or Alumina gel.Acquisition catalyst is sufficiently stirred for when using with the anatase-type nanometer titanium dioxide impregnated of vanadium, tungsten
Lotion, forms plate-type denitration catalyst.The forming agent is only applicable to plate-type denitration catalyst, does carrier to ceramic honey comb and urges
Agent effect is unsatisfactory, without universality；And active component large usage quantity, economy is not enough.
CN103421458A patent prospectus discloses a kind of metal adhesive and preparation method thereof, the bonding
Agent is by epoxy resin, lead powder, dichloroethanes, polyamide, SA dioctyl ester, polysulfide rubber, talcum powder, phthalic acid two
Butyl ester, dicyanodiamine, polyether resin, methanol, benzene composition.Although the binding agent has stronger adhesion strength and peels off caking property
Can, but the bonding between metal and rubber is only applicable to, the shaping of catalyst can not be advantageously applied to.
The content of the invention
The invention provides a kind of powder Catalyst molding adhesive, preferably, preparation process is simple for bond effect,
It is easy to operate, and be applied in the preparation of preformed catalyst, available for catalyst in board-like, honeycomb fashion and corrugated plate dst
Molding bonded in catalyst carrier, while not influenceing the catalytic efficiency of catalyst.
A kind of powder Catalyst molding adhesive, including component A, B component and Ludox, wherein：
Counted by 100 parts by weight of component A, component A is by MTMS 20-60 parts by weight, dimethylformamide dimethyl oxygen
Base silane 10-40 parts by weight, esters solvent 3-12 parts by weight, butyl glycol ether 0.1-3 parts by weight, ester plasticizer 5-15 weights
Measure part and methanol 2-10 parts by weight composition；
Counted by 100 parts by weight of B component, B component is by MTMS 45-75 parts by weight, dimethylformamide dimethyl oxygen
Base silane 10-40 parts by weight, crosslinking agent 0.5-5 parts by weight, methanol 1-6 parts by weight and solvent 1-7 parts by weight composition；
The component A：B component：The weight ratio of Ludox is 0.01-0.3:0.5-1.5:1.
Described Ludox is alkaline silica sol.
Ludox has very high permeability and dispersiveness, and after moisture evaporation in Ludox, colloidal particle is securely
Body surface is attached to, silica is formed and combines, have very high adhesive property, while not influenceing the activity of catalyst.The present invention's
