Polymerization foam concrete cement blowing agent

Abstract

The invention relates to chemical, building material field, more specific is a aggregate foam concrete cement foaming agent. Prefabricating foam concrete moulds and templates and installing on site, preparing foam concrete with different volumetric weight, closed air holes, low water-absorption rate, well water proofing property by surfactant and cement foaming agent, adopting reticular machine, compressing empty foams to prepare foams, cement slurry or mortar, mixing prefabricated foams and cement slurry or mortar, continuously mechanized, semi- mechanized pumping, suspending conveying and pouring on site, foam concrete plates, section steel with different volumetric weight are poured by moulds, composite plates are poured light weight foam concrete in interlayers of metal, plastic, wood and building boards, maintaining naturally or steam maintenance.

Description

Technical field: [0001] The invention relates to the fields of chemical industry and building materials, in particular to a polymerized foam concrete cement foaming agent and a preparation method thereof. Background technique: [0002] There are many kinds and methods of preparing foamed concrete with foaming agent, air-entraining agent and cement foaming agent at present, but there are many deficiencies, which are summarized as follows: [0003] Foaming agents, air-entraining agents, and cement foaming agents currently used in domestic production of foamed concrete; rosin gum foaming agents, resin soap foaming agents, waste animal hair foaming agents, hydrolyzed blood glue foaming agents, petroleum aluminum sulfate foaming agents, rosin Glue and animal glue mixed foam agent is a low molecular foam agent sol. [0004] The characteristics and application effect of the above foam concrete foam agent: [0005] Rosin gum foaming agent, resin soap foaming agent, in the world, r...

AI Technical Summary

Problems solved by technology

[0017] The surface of the prepared foam concrete hard rock has irregular pulverized loose surfaces and cracks, and the overall flatness is low. The pores are open, irregularly flat, linear and tubular, resulting in dry and hard shrinkage. The physical properties of compression resistance, flexural resistance, thermal conductivity, and sound insulation Significantly reduced, losing environmental protection and energy saving requirements

[0018] The surface of the prepared foam concrete hard rock is hydrophobic and repells water, which is not conducive to bonding construction on the hard rock surface, which will reduce the bonding force between objects and cause the paste to fall off

[0019] The water absorption rate of the prepared foam concrete hard rock is as high as 56%, which causes the foam concrete to absorb and store water, resulting in leakage

It is not conducive to the use of walls and heat insulation layers that require high waterproof and sound insulation
