Embodiment

[0043] Table 1

[0044]

[0045]

[0046] According to Table 1, it can be seen that when the raw materials shown in Examples 1 to 7 are operated according to the mass percentage within a certain range and the process temperature within a certain range, the prepared plate has good glassy state, high resistance Flexural strength (for example, ≧50MPa), high Mohs hardness (for example, ≧5 grade) and good gloss (for example, ≧75).

[0047] The present invention has the following technical effects:

[0048] (1) Make the hot blast furnace slag into a product, realize the recovery of the sensible heat of the hot slag, and realize the utilization of the effective components of the hot slag, which not only saves the energy consumed by the secondary melting of the slag, but also It also greatly reduces the production cost of the product, saving resources and energy;

[0049] (2) Compared with the traditional decorative board production process, it can save energy by about 34%, an...

Abstract

The invention discloses a hot blast-furnace slag plate and a preparation method thereof. The hot blast-furnace slag plate comprises the following raw materials by mass: 61-70% of hot blast-furnace slag, 15-25% of silica, 1-5% of boric acid, 2-6% of sodium carbonate, 0.9-3% of aluminum oxide, 0.1-3% of anhydrous sodium sulfate, 0.5-5% of titanium dioxide, 0.1-3% of zinc oxide, 0.1-3% of sodium fluorosilicate and 0.1-1% of antimony trioxide.

Description

technical field [0001] The invention relates to the field of boards, more specifically, to a decorative board produced by using hot blast furnace slag and a preparation method thereof. Background technique [0002] Traditional decorative panels are mainly composed of organic polymers, which contain harmful components such as benzene and formaldehyde, and these harmful components are difficult to eliminate for a long time. Therefore, the development and production of healthy and environmentally friendly inorganic decorative panels have attracted attention. The production cost of inorganic decorative panels is relatively high, mainly because a large amount of energy is consumed in the melting process. Therefore, how to reduce the production energy consumption of inorganic decorative panels is an important direction for the industrialization of inorganic decorative panels. [0003] The low utilization rate of mineral resources and energy is an important problem to be solved in ...
