Embodiment 1

[0018] Weighing by weight components: 300 parts of Portland compound cement, 300 parts of stone powder, 50 parts of fly ash, 450 parts of mature straw. Put the above components into the mixer according to the proportion, add an appropriate amount of water and mix evenly, transport it to the brick making machine, start the machine and vibrate, the pressure is 100MPa, demoulding and curing, and then the straw lightweight fireproof bricks for walls are obtained.

Embodiment 2

[0020] Weighing by weight components: 250 parts of portland compound cement, 350 parts of stone powder, 100 parts of fly ash, and 300 parts of mature straw. Add the above-mentioned silicate compound cement, stone powder and fly ash into the mixer in sequence according to the proportion, add an appropriate amount of water and stir until it becomes a paste, then add the mature straw one after another, add water according to the dry humidity, stir evenly, and transport it to the mold of the brick making machine In the middle, the vibration pressure is 100MPa, and the straw light-weight fireproof brick for wall is obtained after demoulding.

Embodiment 3

[0022] 350 parts of Portland compound cement, 250 parts of stone powder, 100 parts of fly ash, 300 parts of mature straw, add the above components into the mixer in proportion, add an appropriate amount of water, mix evenly, and dry in eight layers of humidity, and transport to the press In the brick machine model, start the machine and vibrate to a pressure of 100MPa, demoulding and curing, and then get straw lightweight fireproof bricks for walls.

Abstract

The invention provides a straw light-weight fireproof wall brick and a preparation method thereof, relating to the technical field of fireproof wall bricks. The straw light-weight fireproof wall brick is composed of silicate compound cement, rock powder, aged straw and fly ash. The preparation method comprises the following steps: proportionally adding the fly ash into a mixing machine, adding water, stirring to obtain a paste, adding the cured straw, supplementing water according to the humidity, uniformly mixing, delivering into a brick making machine model, starting the brick making machine, and carrying out vibration forming. The straw light-weight fireproof wall brick has the advantages of light weight, fire resistance, seepage resistance, higher strength than the filling material in the prior art, and accessible, sufficient and cheap raw materials, is convenient to transport, can not be easily damaged, and can partially solve the problem of environment pollution caused by straw incineration.

Description

technical field [0001] The invention relates to the technical field of fireproof wall bricks, in particular to a lightweight fireproof wall brick made from straw and a preparation method thereof. Background technique [0002] Real estate development is more and more focused on high-rise development. The structure of the house is changed from the original brick and wood to the frame. The frame frame houses need a lot of wall filling materials. The existing technologies include hollow cement bricks, fly ash mixed cement boards, and lime Mixed fly ash foam board, and polyester chemical material board, etc., such as Chinese patent CN102330480A (patent number: CN201010225636.8), a new type of hollow wall brick, discloses a new type of hollow wall brick using clay, powder Made of coal ash, silicate and other materials, the brick body is made of holes of the same shape and size, the center distance between the two holes is equal to the width of the brick, and the length of the bric...
