Modified cement polystyrene mold shell building block and processing process thereof

Abstract

The invention relates to a building block and a processing process thereof, in particular to a modified cement polystyrene mold shell building block and a processing process thereof and belongs to thefield of production and processing of novel building materials. The modified cement polystyrene mold shell building block mainly comprises the following components per unit volume: 230-320 kg of high-grade Portland cement, 6-12 kg of graded polystyrene particles, 0-90 kg of second-stage fly ash, 4-12 kg of an acrylic high-molecular polymer waterproofing agent and 120-170 kg of water. The modifiedcement polystyrene mold shell building block and the processing process thereof, provided by the invention, have the benefits that in mold shell production raw materials, by adding polymer cement slurry jointly formed by the high-molecular polymer waterproof agent and the high-grade cement, after mixing, bonding and hardening with the graded polystyrene particles, a composite thermal insulation material is formed; and through a closed space reticular polymer cement skeleton, the waterproof property of the mold shell building block is changed, the durability and the fire resistance of the moldshell building block are greatly improved, and not only are the thermal insulation property and the fire-resistant property of a wall body met, but also the service life of the wall body is greatly prolonged.

Description

technical field [0001] The invention relates to a block and its processing technology, in particular to a modified cement polystyrene formwork block and its processing technology, which belongs to the field of production and processing of new building materials. Background technique [0002] The development of new wall insulation materials and the promotion of energy-saving buildings are an important part of my country's energy-saving and emission-reduction work, and it is also a basic national policy for my country to save resources and promote economic development. my country has raised energy-saving standards for residential buildings from 65% to 75%, and energy-saving standards for public buildings have also increased from 50% to 65%. However, the current traditional wall and thermal insulation structure system can no longer meet the development requirements of new energy-saving standards and new situations. [0003] The main problems existing in the traditional externa...

AI Technical Summary

Problems solved by technology

[0004] 1. Insulation system: poor safety performance, low grade, fire hazards (flame retardant materials and fire isolation belts) and large area shedding and other safety problems; short service life, high maintenance costs (unreasonable system structure, easy aging deformation, cracking) seepage, etc.);

[0005] 2. Insulation materials: Good insulation (organic materials) is not fireproof and easy to age; fireproof (inorganic materials) has a large volume, air permeability, water permeability, poor insulation performance, and short life;

[0006] 3. Design and application: no load bearing, poor durability, wind load resistance and earthquake resistance
