Anti-freeze hollow brick and preparation method thereof

Abstract

The invention discloses an anti-freeze hollow brick and a preparation method thereof. The hollow brick is composed of the following raw materials in parts by weight: 36 to 38 parts of shale, 1 to 1.2 parts of alum stone powder, 1 to 3 parts of sodium pyrophosphate, 7 to 9 parts of common silicate cement, 6 to 8 parts of curing agent, 3 to 5 parts of polyethylene rubber powder, 0.05 to 0.1 part of urea, 0.1 to 0.2 part of propylene glycol, 3 to 4 parts of urea-formaldehyde resin, 3 to 5 parts of emulsified asphalt, 2 to 3 parts of methyl cellulose with a concentration of 3%, and 4 to 6 parts of YT inorganic active thermal insulation material. The shortages of the prior art are overcome; by adding urea, propylene glycol, warm water, and the like, stirring, and improving the formula and technology, the anti-freeze hollow brick has an excellent anti-freeze effect; the technology does not need steaming and burning, energy is saved, the environment is protected; moreover, the technology is simple, the operation is convenient; the hollow brick can resist freezing, pressing, earthquake, and water, has a thermal insulation function, and is convenient for construction; and the production technology is simple and is easy to control.

Description

technical field [0001] The invention relates to the technical field of hollow bricks, in particular to a frost-resistant hollow brick and a preparation method thereof. Background technique [0002] Blocks are man-made blocks made of concrete, industrial waste (slag, fly ash, etc.) or local materials. demands for institutional reform. Blocks can be divided into solid blocks and hollow blocks according to their appearance and shape. Hollow blocks have three forms: single row of square holes, single row of round holes and multiple rows of flat holes, among which multiple rows of flat holes are more beneficial to heat preservation. As a new type of wall, the wall composed of hollow blocks alone or with reinforced concrete is widely used in the current construction industry. At present, the materials for building masonry include clay bricks, aerated concrete bricks, slag hollow bricks, coal gangue hollow bricks, cement hollow bricks, etc. Among them, the production cost of coa...

Problems solved by technology

With the development of the construction industry, the demand for hollow bricks is increasing. Because the manufacture of hollow bricks consumes a lot of resources, such as clay and cement, the cost is high, it does not conform to the principle of resource conservation, and it cannot meet the needs of society. At the same time, the existing Most hollow bricks have poor frost resistance and are difficult to use at low temperatures
