Abstract
The invention relates to black heat-insulating cotton. The black heat-insulating cotton is prepared by performing wire-drawing or melt-spinning on 50 to 98 percent of heat-insulating cotton and 2 to 50 percent of black powder, wherein the black powder is at least one of graphitized petroleum coke and graphitized pitch coke; and the average grain diameter of the black powder is less than or equal to 20 mu m. The graphitized petroleum coke, the graphitized pitch coke or the mixture of the graphitized petroleum coke and the graphitized pitch coke is used for coloring the heat-insulating cotton to prepare the black heat-insulating cotton and the melting point of the graphitized petroleum coke and the graphitized pitch coke is higher than that of the heat-insulating cotton material, so when wire-drawing or melt-spinning is performed on the heat-insulating cotton material under a melting state, the added black powder is still in a solid state and is not molten.
Description
Technical field
The present invention relates to a kind of black heat-preservation cotton and preparation method thereof, belong to the thermal insulating material technical field.
Background technique
Enterprises such as chemical plant, thermoelectricity plant and boiler plant need utilize the line transportation fluid, and in conveyance fluid, need to keep the temperature stabilization of fluid, therefore can lay heat-preservation cotton to carry out heat-insulation and heat-preservation and protection outside fluid-transporting tubing.The material of heat-preservation cotton is generally selected sial system insulation thermal insulating material (comprising expanded perlite, mineral cotton, expanded vermiculite, slag wool, glass fibre and rock wool) for use, its form is the fluffy state that felting forms, so mobile be obstructed of air in heat-preservation cotton, and the excellent heat insulating performance of these materials itself, therefore heat-preservation cotton can effectively prevent convection current and pass to heat transfer, but the color of the heat-preservation cotton that these materials are made is therefore not high to the radiant heat energy absorption efficiency for being generally light color.
Summary of the invention
The invention provides a kind of black heat-preservation cotton, purpose is to solve the existing heat-preservation cotton problem not high to the radiant heat energy absorption efficiency.
For achieving the above object, the technical solution used in the present invention is: a kind of black heat-preservation cotton, make in wire drawing or after melting and spraying the spray silk by the raw material of following mass ratio:
Heat-preservation cotton 50%～98%;
Black toner 2%～50%;
Wherein, described black toner is at least a in graphitizing petroleum coke, graphitizing pitch coke, high-temperature calcination petroleum coke and the high-temperature calcination pitch coke, and the Mean particle diameter of described black toner is less than or equal to 40 microns.
Related content in the technique scheme is explained as follows:
1, in the such scheme,
Heat-preservation cotton 70%～90%;
Black toner 5%～30%;
2, in the such scheme, the Mean particle diameter of described black toner is 0.5～10 micron, this particle diameter is an optimum scheme, when particle diameter during greater than 20 microns, particle may wire drawing and when silk spray occluding device shower nozzle, and when particle diameter small to below 0.1 micron the time, black toner then is difficult to mix with the heat-preservation cotton material of molten state.。
3, in the such scheme, described graphitizing petroleum coke is that petroleum coke (comprising needle coke, sponge coke etc.) is made through graphitizing in graphitizing furnace.Described petroleum coke (petroleum coke) is that crude oil is after distillation separates weight matter oil, heavy oil is again through the process of hot tearing, the product that is transformed, from in appearance, petroleum coke is a black bulk (or particle) irregularly shaped, not of uniform size, and metallic lustre is arranged, and the element set that group is wanted becomes carbon, occupy more than the 80wt%, remaining is hydrogen, oxygen, nitrogen, sulphur and metallic element.
4, in the such scheme, the graphitizing pitch coke is that pitch coke is made through graphitizing in graphitizing furnace, and described pitch coke is the solid product that is obtained after coking by coal tar pitch.
5, in the such scheme; described graphitizing is to carry out in the atmosphere of shielding gas such as argon gas or nitrogen; structure of molecule is on former carbonization basis in this process; further form " Turbostratic " of class graphite; other hetero atoms beyond the de-carbon further gasify and reduce to below 3%; therefore carbon purity is higher, and fiber modulus and heat resistance and electric conductivity etc. improve with the raising of graphitization temperature, and intensity and elongation percentage descend to some extent.
6, in the such scheme, the heat-preservation cotton material is a sial system insulation thermal insulating material, as expanded perlite, mineral cotton, expanded vermiculite, slag wool, glass fibre and rock wool etc.
Because the technique scheme utilization, the present invention compared with prior art has following advantage and effect:
The present invention adopts graphitizing petroleum coke, graphitizing pitch coke or the two mixture to be used for to the heat-preservation cotton toning to make the black heat-preservation cotton as black toner, because the fusing point of graphitizing petroleum coke and graphitizing pitch coke is higher than the heat-preservation cotton material, therefore, the heat-preservation cotton material carries out wire drawing or melts and sprays the spray silk adding man-hour under molten state, the black toner of interpolation still is not fusion of solid state.
