Method for manufacturing composite mineral wool board for building insulation

Abstract

The invention discloses a method for manufacturing a composite mineral wool board for building insulation. The method uses special interface agents as adhesives, a fiberglass mesh fabric completely wraps the surface of the high-density mineral wool board for the building to improve defects of an inorganic mineral wool board, and the mineral wool board can meet the requirements of national or industrial relevant standards and becomes a level-A non-combustible, flexible, high-strength, waterproof, air-permeable, high-weatherability and heat-insulation mineral wool material for the building. Experiments prove that the composite mineral wool board for building insulation, manufactured by the method, meets the relevant requirements of the national or industrial standards of Rock wool products for exterior insulation and finish systems (GB / T25975-2011), External thermal insulation composite system based on expanded polystyrene (JG149-2003), fire prevention regulations for buildings (GB50016) and the like.

Description

technical field [0001] The invention belongs to the field of chemical building materials, and relates to a manufacturing method of a thermal insulation material that can be applied in a building thermal insulation system. Specifically, it is a composite mineral wool board for building thermal insulation and its manufacturing method, which can improve the defects of the inorganic mineral wool board, so that the product can meet the requirements of relevant national or industry standards. Background technique [0002] Compared with developed countries, there is a clear gap in the quality and application of mineral wool in my country, especially in the field of construction. Only 10% of mineral wool in my country is used in the construction industry. European thermal insulation materials, inorganic fiber materials account for about 60% of the entire market. Organic type materials such as expanded and extruded polystyrene account for about 27% of the market. In the field of bu...

Problems solved by technology

[0012] The main problems in using mineral wool boards for external wall insulation in the future include: the relationship between the chemical composition and durability of mineral wool is not considered; domestic mineral wool inorganic insulation products generally have problems such as low surface strength and poor water resistance; In the construction and construction process of the external thermal insulation system of the external wall, the method of simply applying the organic thermal insulation board, there is no construction plan for mineral wool thermal insulation products, etc.

These problems have seriously restricted the use of mineral wool in the construction field, making the current external wall insulation project with high safety level requirements face the embarrassing situation that there is no material available.
