Problems solved by technology

[0002] After clay bricks are disabled, although there are light-weight aerated cement blocks with better thermal insulation properties as wall materials, the investment is large and it is not easy to popularize, especially the material is loose and the slurry is easy to fall off. Low and poor security, the current porous cement bricks are only made of cement and sand or slag mixed with crushed materials, whether it is sand and gravel bricks, fly ash bricks or metal slag powder bricks and coal gangue bricks, there is no lightweight Insulation materials are blended and produced, not only the bricks are too heavy, but also permeable to water and heat. In order to achieve heat insulation, another insulation layer must be made, which is labor-intensive, easy to delaminate and damage, not durable, high cost, and long construction period

Embodiment 1

[0014] The production process of the lightweight thermal insulation brick is as follows: 1. Weigh 8 to 15% of the cementitious material, 30 to 50% of the bone material, 25 to 55% of the light material, and 1% to 2% of the auxiliary agent by weight, Waterproof powder 3% to 4%; 2. Stirring: the early strength agent is first mixed with water, and then mixed with various ingredients through a mixer. And the hardness is not good, the over-wet material will stick to the mold, the product is fragile and difficult to demould; 3. Pressing: convey the ingredients into the brick making machine for pressing and forming; 4. Palletizing: the product has just been pressed and formed, and the strength is extremely poor. It is advisable to stack up to 4 boards to avoid unnecessary losses; 5. Maintenance: After the products are stacked, spray water for maintenance once the next day, that is, start stacking after 72 hours, and spray water for maintenance once a day. After the fifth day, it will n...

Embodiment 2

[0019] The production process of the light insulating brick is as follows: 1. Take by weight 10% of cement, 35% of crushed materials such as miscellaneous sand or slag, slag, coal gangue, perlite or its waste slag powder or waste foam crushed materials, Carbide slag, sawdust, coal ash powder and other light materials 50%, early strength agent 1%, waterproof powder 4%; 2. Stirring: early strength agent is first mixed with water, and then mixed with various ingredients through a mixer. It is advisable to be able to knead into a ball without wet hands. If the product is too dry, it will not be pressed into shape, and the hardness is not good. If the material is too wet, it will stick to the mold, and the product will be easily damaged and difficult to demould; Forming; 4. Palletizing: The product has just been pressed and formed, and its strength is extremely poor (lower than the palletizing of cement sandstone bricks). It is advisable to stack 3 to 4 boards to avoid unnecessary l...

Embodiment 3

[0024] The light material content in the brick body is more than 40%. It is an insulating brick, which is suitable for hot and cold areas. Thermal (board) bricks, the middle wall is only 9 to 12cm wide. The production process of the light insulating brick is as follows: 1. Take by weight 10% of cement, 50% of broken materials such as miscellaneous sand or slag, slag, coal gangue, perlite or its waste slag powder or waste foam broken materials, Calcium carbide slag, sawdust, coal ash powder 35%, early strength agent 1.5%, waterproof powder 3.5%; 2. Stirring: early strength agent is first mixed with water, and then mixed with various ingredients through a mixer, and the ingredients can be kneaded into a ball It is advisable not to wet your hands. If the product is too dry, it will not be formed by pressing, and the hardness is not good. If the material is too wet, it will stick to the mold, and the product will be easily damaged and difficult to demould; Palletizing: The produc...

Abstract

The invention relates to the field of building materials, in particular to a lightweight insulating brick. The lightweight insulating brick is prepared by mixing the following raw materials: 8 to 15 percent of gelled material, 30 to 50 percent of aggregate, 25 to 55 percent of lightweight material, 1 to 2 percent of aids and 3 to 4 percent of waterproof powder. Because lightweight materials of industrial and agricultural wastes are added into the lightweight insulating brick, the lightweight insulating brick changes waste into valuable, protects the environment, is energy-saving, insulates sound and heat, has strong insulating property and is warm in winter and cool in summer; and compared with an air-entrained cement building block, the lightweight insulating brick has the advantages of strong water resistance, water leakage resistance, high strength, strong safety, good compactness, slurry drop resistance, low investment and easy popularization.
