Description
Technical field
The present invention relates to more particularly to a kind of poroid coal ash heat-preservation material of honeycomb preparation method.
Background technology
Contain a large amount of SiO in flyash component2And Al2O3, there is higher industrial recycle value.Hanzhong zinc industry has
The flyash fine ash granularity generated in the production of limit responsible company is more than 200 mesh accounts for 90%, granularity accounting for more than 400 mesh
20%, surface is modified to form good interface cohesion, the exploitation available for flyash-resin composite materials with resin.Powder
Coal ash-resin composite materials can be used for the fields such as decorating building, wall sound-insulating layer, can not only be that enterprise brings economy
Benefit, moreover it is possible to preserve the ecological environment and generate social benefit.
Existing utilization of fly ash technology is concentrated mainly on the fields such as building, agricultural, chemical industry, sewage disposal, most of applications
Technology content it is not high, and the technology that some technology contents are higher cannot be wide since application cost is high, technological process is complicated
General popularization and application.
Invention content
The technical problems to be solved by the invention are to provide a kind of poroid flyash of honeycomb in view of the deficiencies of the prior art to protect
The preparation method of adiabator.
Technical scheme is as follows：
A kind of Preparation Method of the poroid coal ash heat-preservation material of honeycomb, includes the following steps：Fly ash surface modification：Take 1000
The flyash of 400 mesh of parts by weight is spare, and the absolute ethyl alcohol for then taking the weight such as the tetramethoxy-silicane use of 50~100 parts by weight is dilute
After releasing, in dropping evenly flyash in the case where being sufficiently stirred, treat that flyash is sufficiently impregnated being placed on 60~80 DEG C
Abundant drying for standby in drying box；
The configuration of flyash-epoxy resin slurry：1000 parts by weight epoxy resin are substantially dissolved in the mixing container
In 100~200 pbw acetones, 200~300 weight parts of polyamide 650 are then added in, are stirring evenly and then adding into 500 parts by weight
400 mesh flyash after surface-modified, stir rear spare；
The molding of the poroid coal ash heat-preservation material of honeycomb：By the flyash being configured-epoxy resin slurry injection moulding mould
In tool, mold is placed in 130~170 DEG C of drying box after heating 10~40min and stops heating, case natural cooling to be dried
Afterwards, product is removed from the molds up to the poroid coal ash heat-preservation material of honeycomb.
This patent utilizes the SiO in flyash2And Al2O3Space tetrahedral structure, using appropriate surface modifier,
Make SiO2And Al2O3Space structure extend outwardly, and under certain molding technological condition, with epoxy resin, curing agent form
Organic system carries out compound, formation flyash-resin composite materials spatial cell cavernous structure.The composite material has thermal insulation
Well, the features such as good waterproof performance, porous light, easy coloring, low production cost, it can be applied to wall sound-insulating layer of building etc.
Field.

2nd, the Preparation Method of the poroid coal ash heat-preservation material of honeycomb
The screening of flyash and surface are modified：The sieve of 80 mesh, 200 mesh and 400 mesh is sequentially overlapped, is placed on vibrating screen
Flyash is screened, the poroid coal ash heat-preservation material of honeycomb uses the flyash of 400 mesh as raw material.Take 1000g flyash spare,
Then after the absolute ethyl alcohol of the tetramethoxy-silicane equivalent of 50~100g or so is taken to dilute, in the case where being sufficiently stirred uniformly
It is added drop-wise in flyash, treats that flyash is sufficiently impregnated being placed on abundant drying for standby in 60~80 DEG C of drying box.
The configuration of flyash-epoxy resin slurry：1000g epoxy resin is substantially dissolved in 100 in the mixing container~
In 200g acetone, then add in 200~300g polyamide 6s 50, be stirring evenly and then adding into 500g or so it is surface-modified after 400
Mesh flyash stirs rear spare.
The molding of the poroid coal ash heat-preservation material of honeycomb：By the flyash being configured-epoxy resin slurry injection moulding mould
In tool, mold is placed in 130~170 DEG C of drying box after heating 10~40min and stops heating, case natural cooling to be dried
Afterwards, product is removed from the molds up to the poroid coal ash heat-preservation material of honeycomb.
The poroid coal ash heat-preservation material of honeycomb has an excellent, ultralight performance characteristics of heat insulation effect, and thermal conductivity≤
0.03W/ (m.K), density are only 0.23g/cm3Left and right.
It should be understood that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
