Abstract
The invention discloses a preparation method of a honeycomb-hole-shaped pulverized coal ash thermal insulation material. The preparation method comprises the following steps of: modifying the surface of coal ash; preparing slurry of coal ash and epoxy resin; and molding the honeycomb-hole-shaped pulverized coal ash thermal insulation material. The spatial tetrahedron structures of SiO2 and Al2O3 are utilized and an appropriate surface modifier is used to externally extend the spatial tetrahedron structures of SiO2 and Al2O3; and the spatial tetrahedron structures of SiO2 and Al2O3 are compounded with an organic system which is formed by epoxy resin and a curing agent under the conditions of a certain molding technology, and therefore the spatial honeycomb-hole-shaped structure of a composite material of pulverized coal ash and resin is formed. The composite material has the characteristics of being good in thermal insulation and water resistance, light in weight with multiple holes, easy to color, low in production cost, and the like, and the composite material can be used in the fields of a sound insulation and thermal insulation layer of a wall body of a building, and the like.

Existing utilization of fly ash technology mainly concentrates on the fields such as building, agricultural, chemical industry, sewage disposal, the technology content that great majority are used is not high, and the higher technology of some technology contents is high due to application cost, technical process is complicated and can not be applied widely.
Summary of the invention
Technical problem to be solved by this invention is to provide the poroid coal ash heat-preservation material preparation of a kind of honeycomb method for the deficiencies in the prior art.
Technical scheme of the present invention is as follows:
The Preparation Method of the poroid coal ash heat-preservation material of a kind of honeycomb, comprise the following steps: fly ash surface modification: get 1000 weight part 400 purpose flyash standby, then after the tetramethoxy-silicane of getting 50～100 weight parts such as uses at the dehydrated alcohol dilution of weight, evenly be added drop-wise to flyash in well-beaten situation in, treat that flyash is fully flooded abundant drying for standby in the loft drier that is placed on 60～80 ℃;
The configuration of flyash-epoxy resin slurry: in mixing vessel, 1000 weight part epoxy resin fully are dissolved in 100～200 weight part acetone, then add 200～300 weight parts of polyamide 650, add the 400 order flyash of 500 weight parts after surface modification after stirring, stir rear standby;
The moulding of the poroid coal ash heat-preservation material of honeycomb: in the flyash that configures-epoxy resin slurry injection moulding mould, mould is placed in the loft drier of 130～170 ℃ heats stopped heating after 10～40min, after case naturally cooling to be dried, product is taken out from mould namely get the poroid coal ash heat-preservation material of honeycomb.
This patent utilizes the SiO in flyash
