Abstract

The invention discloses a preparation method of a silicon calcium thermal insulation material. The preparation method comprises the following steps: using carbide slag and silica fume as raw materials; mixing uniformly at a certain proportion; calcining in a rotary kiln, wherein the calcination temperature is 750 DEG C and the calcination time is 2 hours; taking out and cooling to room temperature; adding water, injecting into a reactor provided with a stirring device; heating to 200 DEG C; constantly stirring for 8 hours; naturally cooling to room temperature; adding 5% of glass fiber to rankinite slurry; stirring uniformly; filling into a mold for pressing and molding; drying a demolded mold block to obtain the silicon calcium thermal insulation material.

Description

A kind of preparation method of silico-calcium heat-insulating heat-preserving material
Technical field
The present invention relates to trade waste resource utilization technology field, and in particular to a kind of silico-calcium heat-insulation and heat-preservation material The preparation method of material.
Background technology
At present, the production of heat-insulating heat-preserving material mainly adopts quick lime, slaked lime for raw material, needs to exploit large quantities of lime Stone, so as to destroy vegetation, damages to ecological environment.Carbide slag is the waste residue that TV hydrolysis obtains acetylene, and carbide acetylene Enterprise will discharge every year substantial amounts of carbide slag.How carbide slag reasonably to be comprehensively utilized, turning waste into wealth seems extremely urgent.
The content of the invention
The technical problem to be solved is for the deficiencies in the prior art, there is provided a kind of new trade waste Recovery and utilization technology and the method for preparing silico-calcium heat-insulating heat-preserving material using garbage.
The technical problem to be solved is realized by following technical scheme.It is raw materials used for carbide slag And silicon ash, according to a certain percentage mix homogeneously, with calcined by rotary kiln, calcining heat is 750 DEG C, and calcination time is 2 hours, is taken Go out, be down to room temperature, add water, in reactor of the injection with agitating device, be warming up to 200 DEG C, be stirred continuously 8 hours, drop naturally To room temperature.5% glass fibre is added in silicoglaserite slip, is stirred, be fitted into compressing in mould, after the demoulding Module is dried.
Compared with prior art, the insulation material that prepared by the present invention has light weight, good heat insulating, while being also also to be The comprehensive utilization of carbide slag provides an effective approach, slows down the destruction that exploitation limestone is caused to ecological environment, realizes society The doulbe-sides' victory of meeting environmental benefit and economic benefit.
Specific embodiment
Raw material.The raw materials used waste residue carbide slag and silicon ash for carbide acetylene enterprise of the present invention, rejects impurity, standby.
Calcining.Ratio according to 1 ﹕ 1 mixes carbide slag and silicon ash, mix homogeneously, and with calcined by rotary kiln, calcining heat is 750 DEG C, calcination time is 2 hours, is taken out, and is down to room temperature.
Slurrying.25 times of water of waste material quality after calcining are added, in reactor of the injection with agitating device, 200 DEG C is warming up to, It is stirred continuously 8 hours, room temperature is down to naturally.
Molding.5% glass fibre is added in silicoglaserite slip, is stirred, in being fitted into mould, in 0.5 MPa of pressure It is compressing under power.
Drying.Module after the demoulding is dried at 120 DEG C.
