Problems solved by technology

[0003] However, negative oxygen ion materials are prone to agglomeration, which not only affects the continuity of negative oxygen ion mineral wool board production and reduces production efficiency, but also adversely affects the negative oxygen ion function of negative oxygen ion materials.
At present, no mineral wool board products with negative oxygen ion materials have been found in the market

Abstract

The invention provides a mineral wool board and a preparation method thereof. The raw materials of the mineral wool board include granular cotton, konjac flour and negative oxygen ion materials. Optional raw materials may also include attapulgite, modified starch and flocculants. The preparation method of the mineral wool board comprises the following steps: first, fully mixing konjac powder, negative oxygen ion materials and water; secondly, after fully stirring the mixed material and the remaining ingredients prepared in the previous step with water in a mixer, making A mixed slurry is obtained; finally, the mixed slurry is molded and dried to obtain a mineral wool board. The mineral wool board prepared by the method of the invention can effectively avoid the agglomeration of negative oxygen ion materials, and can release a large amount of negative oxygen ions, effectively purify the air, obviously reduce air peculiar smell, and improve the indoor living environment.

Description

technical field [0001] This article relates to mineral wool board building material technology, specifically a mineral wool board and its preparation method, especially an environmentally friendly mineral wool board with the function of releasing negative oxygen ions and its preparation method. Background technique [0002] After research, it was found that air negative oxygen ions have the functions of purifying air, sterilizing and deodorizing, etc. Negative oxygen ion materials such as germanium are semiconductor materials between metals and non-metals. They can not only release negative oxygen ions, but also emit far-infrared rays in the 4-14 μm band that can be absorbed by the human body, which is beneficial to human health. It is a good far-infrared radiation element. [0003] However, negative oxygen ion materials are prone to agglomeration, which not only affects the continuity of negative oxygen ion mineral wool board production, reduces production efficiency, but ...
