Abstract

The invention discloses a hollow-core rock wool and a preparation method and applications thereof, belonging to the field of temperature-preservation and heat-insulation materials. The hollow-core rock wool consists of the following materials by weight percentage: 60-70% of basalt, 20-30% of dolomite, 2-6% of diabase, and 4-8% of fluorite. After being mixed evenly, the materials are put into a cupola and melted at high temperature of 900-1000 DEG C, and then the hollow-core rock wool is obtained. The rock wool has long fiber, good temperature-preservation and heat-insulation properties, fireproofing capability, good elasticity, strong tensile force and good hand-feel, thus being head and shoulders above the slag cotton. All properties are in full compliance with standards of nation, national defense, industry, aerospace, navigation, construction, petroleum, chemical industry, and agriculture. The hollow-core rock wool can be used for the industries such as electric power, chemical industry, petroleum, construction, metallurgy, textile, shipping, automobile, train, airplane, heating pipe and the like, and is the temperature-preservation and heat-insulation material of industrial equipment such as pipeline storage tanks, boiler flues, heat exchangers, large airports, gyms, large-scale cold storage and the like, and civil building engineering.

Description

technical field [0001] The present invention relates to a heat preservation and heat insulation material, in particular to a hollow rock wool with heat preservation and heat insulation properties which is mainly prepared from basalt ore as a raw material. The invention also relates to the preparation method and The application belongs to the field of thermal insulation and heat insulation materials. Background technique [0002] Rock wool is an inorganic fiber made from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc., which are melted and fiberized at high temperature. Rock wool product is a kind of heat preservation and heat insulation material, which has the characteristics of light weight, heat preservation, heat insulation, flame retardant, sound insulation, energy saving, corrosion resistance, acid and alkali resistance, etc. Its main chemical components are silicon dioxide, trioxide Magnesium, Magnesium Oxide and Calcium Oxide. Compared with t...
