Abstract

The invention belongs to the technical field of buildings, and provides seamed rock wool. The seamed rock wool comprises a rock wool board, gridding cloth is seamed on two sides of the rock wool boardthrough fiber threads, and a mortar layer is composited on at least one side of the seamed gridding cloth and the rock wool board, the mortar layer comprises Portland cement, silica sand, calcium carbonate and water according to the mass ratio of (100-120): (45-60): (4-8): (28-40). The rock wool board is cut and formed, gridding cloth is composited on the surface of the rock wool board, the gridding cloth is sewn through fiber lines, and a rock wool composite layer is obtained; portland cement, silica sand, calcium carbonate and water are mixed and stirred into mortar, and then the mortar issmeared on the rock wool composite layer in a batched mode to obtain the seam-bound rock wool. By means of the technical scheme, the problem that in the prior art, a rock wool insulation board is poorin waterproof performance is solved.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to a sutured rock wool and a preparation method thereof. Background technique [0002] Rock wool insulation board is made of natural basalt as the main raw material. After high-temperature melting, it is made into inorganic fibers through high-speed centrifugal equipment. Cotton insulation products. However, due to its loose layered structure, it has low strength and high water absorption, which restricts the application of this product to a certain extent. The external wall thermal insulation rock wool thin plastering system is to paste the rock wool insulation board to the wall foundation and then hang the plastering mortar on the surface of the rock wool insulation board, and embed the alkali-resistant mesh cloth in two-thirds of the mortar to make the rock wool The insulation board, mesh cloth and mortar layer are well consolidated, which improves the strength of the rock w...
