Embodiment 1

[0023] A kind of rock wool, comprises the preparation raw material of following parts by weight: 150kg of basalt, 65kg of dolomite, 45kg of slag, 25kg of coke, 6kg of Suianite; the particle size of basalt is 2mm; the particle size of dolomite is 1mm; The particle size of Ashstone is 1mm.

[0024] The preparation method of described rock wool is characterized in that, carries out according to the following steps:

[0025] (1) Get 150kg of basalt, 65kg of dolomite, 45kg of slag, 25kg of coke, and 6kg of Suian stone, send them into the raw material system, and mix uniformly;

[0026] (2) Feed the material into the cupola, the combustion-supporting air is first preheated to 500°C by the preheating system, and mixed with oxygen, then the oxygen-enriched hot air is blown in from the lower part of the furnace body, the temperature rises to 1800°C, and the material softens. The hot melt is formed, and the hot melt continues to flow down to contact with the hot coke and flue gas, flow...

Abstract

The invention discloses a rock wool and a preparation method thereof. The preparation raw materials include the following parts by weight: 100-200 parts of basalt, 50-80 parts of dolomite, 30-80 parts of slag, 20-30 parts of coke, and 3-10 parts of Suianite. The rock wool prepared by the invention has good toughness and freeze-thaw resistance, and the melting adopts oxygen-enriched combustion technology, which has high efficiency. The outlet of the forming conveyor is connected to a weighing belt conveyor, and a pleating machine is installed between the weighing belt conveyor and the curing furnace. And press machine, high degree of automation, adding Suian stone as an auxiliary agent in the preparation of raw material components, which increases the strength, toughness and freeze-thaw resistance of the material.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to rock wool with good thermal insulation performance and high toughness and a preparation method thereof. Background technique [0002] Rock wool originated in Hawaii. After the first volcanic eruption on Hawaii Island, the residents on the island found strands of melted soft rocks on the ground. This is the rock wool fiber that humans first recognized. The production process of rock wool is actually simulated. The natural process of Hawaiian volcanic eruption, rock wool products are made of high-quality basalt, dolomite, etc. After collecting agent, anti-dust oil and water-repellent agent, they are collected by the cotton collector, passed through the pendulum method, and then solidified and cut by the three-dimensional method to form rock wool products with different specifications and uses. [0003] Rock wool can be used as the main material o...
