Embodiment 1

[0021] The present invention proposes a method for preparing high-strength sound-insulating and heat-insulating refractory bricks from fully recycled materials, which includes the following steps:

[0022] Step 1: After repeated mechanical crushing of the refractory bricks from the recycled steel plant, pass through a 200-mesh sieve, take the sieve to make refractory brick fine powder; pass through a 50-mesh sieve, take the sieve to make refractory brick particles;

[0023] Step 2: Make the straw into 20-40cm long section, use heavy rolling to eliminate the stress of the straw, repeatedly crush the straw, and finally become thin strips below 3cm;

[0024] Step 3: Stir the papermaking white mud slag, straw thin strips and refractory brick particles evenly, press and shape it on a brick press under the pressure of 200T, and make A-layer prefabricated bricks of sound-insulating and heat-insulating refractory bricks; the A-layer prefabricated bricks The thickness is 5cm, and the l...

Abstract

The invention discloses a method for producing high-strength sound and heat insulation refractory bricks from complete recycled materials. The method completely uses recycled raw materials, and adopts papermaking white sludge, straws and recovered steel factory refractory bricks, and the B layer of every produced refractory brick is a compact refractory brick structure and plays a good role in fireproofing, and the A layer of every refractory brick is a sound and heat insulation layer, so the refractory bricks produced in the invention have the advantages of low cost and good effects, and accord with national sustainable development strategy requirements.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a method for preparing sound-insulating and heat-insulating refractory bricks using recycled materials. Background technique [0002] my country's building energy consumption per unit area is still 3-5 times that of developed countries. With the continuous deepening of energy-saving work in residential construction in my country, building energy-saving methods for external wall insulation are becoming more and more popular. House fires caused by large-scale flammable insulation materials occur from time to time. The painful lessons of building fires are vividly remembered by Chinese people. Inorganic fireproof building insulation materials have gradually become a hot spot in the market. Among them, cement foam insulation board, foam ceramic board, foam glass board, etc. have become the leading products, but these materials generally have the disadvantages of high en...
