Production method of mineral wool boards

Abstract

The invention relates to a production method of mineral wool boards, which mainly comprises the following steps: adding foaming agent to a binder; dosing: mixing the foaming agent, the binder, mineral fiber cotton, a flocculating agent and a desiccant; stirring the ingredients evenly, and enabling mineral wool boards to be formed in a coarse manner; adopting the wet process fourdrinier wire beater-addition process to eliminate moisture in the coarse-formed mineral wool boards; putting the coarse-formed mineral wool boards in a hot and humid environment for drying and evaporation; performing primary coarse cutting and planing the surfaces of the coarse-formed mineral wool boards; performing primary spraying on the surfaces and drying the coarse-formed mineral wool boards; performing knurling on the surfaces of the coarse-formed mineral wool boards; performing secondary refined cutting, and tenoning on the periphery; performing secondary spraying on the surfaces and drying, so that the finished products of the mineral wool boards are acquired. The mineral wool boards produced with the method disclosed by the invention possess excellent sound absorption and dampproof functions, more cavities and low density, save cost, and can be better applicable to various fields of building materials decoration.

Description

technical field [0001] The invention relates to a production method of a mineral wool board. Background technique [0002] Mineral wool board is a new type of environmentally friendly building material made of mineral fiber cotton. It has multiple functions such as decoration, sound absorption, heat preservation, heat insulation, fire prevention, and lightness. The biggest feature is that it has good sound absorption and heat insulation effects. Mineral wool is a floc that is thrown out by a high-speed centrifuge after slag is melted at high temperature. It is harmless and pollution-free. It is a green building material that turns waste into treasure and is beneficial to the environment. Therefore, mineral wool board has strong applicability in the construction field. [0003] The traditional method of producing mineral wool board is wet production, that is, mineral fiber cotton is first prepared, and then water, organic binder (such as formaldehyde phenol, phenolic resin o...

AI Technical Summary

Problems solved by technology

The disadvantage of wet forming mineral wool board is that the density of this board is high and the sound absorption performance is not good

Moreover, for the mineral wool board produced by the traditional wet method, since the surface needs to be planed, if the required finished product is 15mm thick, at least 16.5mm is required for molding, thus increasing the amount of material used
