Problems solved by technology

Rock wool board is mainly because of its good thermal insulation effect and flame retardant effect, so it has been widely used in the construction industry. The existing rock wool board mainly focuses on the thermal insulation and flame retardancy of the rock wool board itself, while sound absorption and noise reduction There are relatively few studies on rock wool, and the noise in the existing external environment is relatively large. How to ensure the insulation and flame retardancy of the produced rock wool board, and also have a good function of attracting noise has become a problem that many manufacturers have to solve.

Abstract

The invention relates to a production technology of a rock wool board with the functions of sound absorption and noise reduction. The production technology includes the following steps that corn stalk fibers, sugarcane fibers and chitosan are stirred and smashed; after anaerobic fermentation, filtration and drying are conducted; after polyvinyl alcohol, calcium oxide and mugwort leaf oil are uniformly mixed, a circuit is closed; two obtained mixtures are mixed and compressed; after activated carbon is added and reflux condensation is conducted, hydroxyl acrylic resin and thermosetting phenolic resin are added, smashed and grinded; after ultrasonic dispersion, a mixture is taken out, silica sand is added, and dolerite, dolomite, hydroxyapatite, perlite, expansile graphite, phenolic resin, moisture repellent and a coupling agent are added and mixed; after being fused at a high temperature, a mixture is subjected to centrifugal rotation and wafted to a wool collecting machine; a pendulum method is adopted, the mixture is folded to be of a rock wool structure, and a binding agent is sprayed; wool filaments are solidified, cut and subjected to edge cutting, and the rock wool board is obtained. By the adoption of the production technology of the rock wool board with the functions of sound absorption and noise reduction, the produced rock wool board has the functions of sound absorption and noise reduction and can effectively reduce the disturbance of external noise.

Description

technical field [0001] The invention relates to rock wool boards, in particular to a production process for rock wool boards with sound-absorbing and noise-reducing functions. Background technique [0002] With the rapid development of my country's national economy, architectural styles and types emerge in endlessly, and the requirements for the application of building energy-saving materials and fire safety protection are also getting higher and higher. Rock wool board was introduced into China in the late 1990s, and after more than 10 years of rapid development, it has been widely recognized and has become the first choice for many engineering projects. Rock wool board is mainly because of its good thermal insulation effect and flame retardant effect, so it has been widely used in the construction industry. The existing rock wool board mainly focuses on the thermal insulation and flame retardancy of the rock wool board itself, while sound absorption and noise reduction Th...
