Abstract

The invention discloses a preparation method of a high-cracking resistance rock wool board, belonging to the technical field of preparation of rock wool boards. According to the preparation method, the rock wool board with high cracking resistance and bonding strength is prepared by taking basalt fibers as a main material and rubber powder polyphenyl particles, glass melting liquid, quartz sand and the like as reinforcing filling materials, and the main material and the reinforcing filling materials are firmly connected together, so that the bonding strength of the rock wool board is effectively improved; polystyrene is foamed by virtue of a foaming agent to form a hard hole-closed structure, and formed polystyrene particles are dually modified by virtue of a bonding agent and a silane coupling agent, so that the bonding strength of the rock wool board is improved; the glass melting liquid is modified by virtue of polyethylene glycol stearate, so that the expansion of cracks can be inhibited, the mechanical property of the rock wool board can be improved; and after glass fibers are modified, the contact areas with the basalt fibers are increased by virtue of rough surface structures, the bonding strength of an interface can be substantially enhanced, the cracking resistance and bonding strength of the rock wool board are further improved; and the preparation method has wide application prospects.

Description

technical field [0001] The invention discloses a preparation method of a high-crack-resistant rock wool board, which belongs to the technical field of rock wool board preparation. Background technique [0002] Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. Rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has light weight, small thermal conductivity, The characteristics of heat absorption and non-combustibility, the initial development is a common application type in construction, and it is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". [0003] Implementing energy conservation and emission reduction policies for buildings is a strategic task in my country. As a key indicator of green bu...
