Problems solved by technology

[0006] However, when producing thicker mineral wool boards, due to the high size of the slurry pile, it is difficult to filter water from the mineral wool boards and the loss of components is large during the water filtration process, and the distribution of active ingredients such as clay and starch in the upper and lower parts of the wet board is uneven. Even, in the subsequent vacuum pumping, the moisture content of the wet board is mainly reduced by the backlog of the upper and lower floating rollers, which further leads to the loss of effective components, and the rebound of the wet board is large, which increases the cost of subsequent drying, planing and other processes. Difficulty of operation

Abstract

The invention relates to a board for producing pyramid-shaped mineral wool boards. The board is obtained by mixing all components with water, and carrying out forming and drying, wherein the components include granular wool, a reinforcing agent and a flocculating agent, and with the weight of the granular wool as reference, the use level of the reinforcing agent is 19.4-26.84%, and the use level of the flocculating agent is 1.07-1.13%. The board for producing pyramid-shaped mineral wool boards has a large thickness and a high bending failure load, effectively solves the problems of water filtration difficulty in the production process of thick mineral wool boards in the prior art and serious component loss in the water filtration process, and can meet the performance requirement of decoration processing and improve the decoration performance of mineral wool boards.

Description

technical field [0001] The invention relates to a mineral wool board and a preparation method thereof, in particular to a board for producing pyramidal mineral wool boards and a preparation method thereof. Background technique [0002] Mineral wool board is a new type of building material. Because of its excellent sound absorption, heat insulation and fire resistance, it is widely used in the ceiling of buildings at home and abroad. In recent years, as people demand conditions for the living environment With the continuous improvement of the society, the mineral wool board is required to have higher decorative performance. [0003] At present, in order to improve the decorative performance of the mineral wool board, carvings are usually carried out on the surface of the mineral wool board or new edge shapes are developed. However, due to the thinness of the existing mineral wool boards, usually 10-15mm, the bending failure load is relatively low, so they often cannot meet t...
