Problems solved by technology

Existing inorganic mineral wool board external wall insulation structure has excellent fireproof and thermal insulation properties, but because of the low strength of inorganic mineral wool itself, the tensile strength of inorganic mineral wool board is not high, generally less than 10KPa, and because of mineral The cotton structure is stitched with hot-dip galvanized steel wire grid. Due to the poor corrosion resistance of the hot-dip galvanized steel wire grid, the outer wall is easy to crack due to corrosion after a long time. In addition, because the hot-dip galvanized steel wire grid is hard, It is also more difficult to construct in the door and window openings

Abstract

The title of the present invention is basalt rope and its production method, which belongs to the technical field of basalt fiber production. It mainly solves the problems of low tensile strength, difficult operation on site, allergies of personnel, cracking of the external wall caused by hot-dip galvanized steel wire grid and difficult construction in the external thermal insulation structure of the external wall of the mesh-woven cotton board. Its main features are: its composition contains by mass percentage: SiO 2 : 49‑56%, Al 2 o 3 : 14‑18%, MgO: 5.0‑9.0%, Fe 2 o 3 : 10.0‑11.6%, CaO: 7.5‑8.27%, K 2 O: 0.5‑3.33%, Na 2 O: 0.3‑3.68%, TiO 2 : 1.0‑2.0%; it is formed by drawing, unwinding and twisting basalt fiber spun yarns with a diameter of 7-9 μm; during the drawing process, polymer emulsion is coated on the surface of basalt fiber spun yarns; unwinding and twisting twists reach 160 Twisted above; the basalt rope formed after twisting is coated with a coating and then dried to set the shape. The invention has the characteristics of excellent alkali resistance, good flexibility, bending resistance and convenient construction, and is mainly used for integral sewing of rock wool boards and glass fiber nets covering the surface.

Description

technical field [0001] The invention belongs to the technical field of basalt fiber production, and in particular relates to a basalt rope produced by using basalt fiber and a method for producing the basalt rope. Background technique [0002] In recent years, due to the frequent occurrence of building exterior wall fire incidents caused by exterior wall insulation materials, the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development jointly issued requirements that the exterior insulation of civil buildings must use materials with a combustion performance of Class A. Changes in exterior insulation materials and structures. Existing inorganic mineral wool board external wall insulation structure has excellent fireproof and thermal insulation properties, but due to the low strength of inorganic mineral wool itself, the tensile strength of inorganic mineral wool board is not high, generally less than 10KPa, and due to mineral The cotton structure ...
