Problems solved by technology

[0002] With the development of the national economy, the two functions of fire prevention and heat preservation and energy saving of building materials need to be solved at the same time. At present, the fire performance of general insulation materials in the market is extremely poor, while rock wool with better fire performance cannot meet the energy saving service life. Now Some rock wool sandwich composite panels mostly collapse and fall off due to moisture degumming. In addition, most of the currently used rock wool sandwich composite panels are processed by mechanical fixing and on-site bonding. The finished product has the defects of heat preservation effect and service life that cannot meet market demand

Abstract

The invention relates to a rock wool sandwich composite board, and a preparation method and application thereof. The rock wool sandwich board sequentially comprises a surface layer (2), a sandwich layer (4) and a back layer (6), wherein one face of the sandwich layer (4) is fixedly connected with the surface layer (2) through a first bonding layer (3) and the other face of the sandwich layer (4) is fixedly connected with the back layer (6) through a second bonding layer (5); the sandwich layer (4) consists of rock wool stripes (41) which are arranged in a staggered manner; one face of each rock wool stripe is fixedly connected with the surface layer (2) through the first bonding layer and the other face of the each rock wool stripe is fixedly connected with the back layer (6) through the second bonding layer (5); and fibers of the rock wool stripes (41) are vertical to the surface layer (2) and the back layer (6). By the rock wool sandwich composite board, the phenomenon of collapse and fall, caused by damp and debonding, of rock wool can be avoided; by adopting a good bonding formula, a welding process and a screw fixing mode are not required; the obtained product has high strength and high flatness and hardly becomes damp and falls off; furthermore, the shortcomings of low fireproof performance of the conventional composite board and low heat preservation performance of the rock wool can be overcome at one time.

Description

technical field [0001] The invention relates to a composite board for construction, in particular to a rock wool sandwich composite board and its preparation method and application. Background technique [0002] With the development of the national economy, the two functions of fire prevention and heat preservation and energy saving of building materials need to be solved at the same time. At present, the fire performance of general insulation materials in the market is extremely poor, while rock wool with better fire performance cannot meet the energy saving service life. Now Some rock wool sandwich composite panels mostly collapse and fall off due to moisture degumming. In addition, most of the currently used rock wool sandwich composite panels are processed by mechanical fixing and on-site bonding. The finished product has the defects that heat preservation effect and service life cannot meet market demand. Contents of the invention [0003] The technical problem to be...
