Abstract

The invention discloses a high-performance foam light soil foaming agent and a preparation method thereof.The high-performance foam light soil foaming agent is prepared from, by mass, 20%-50% of a surfactant, 5%-15% of a foam stabilizer, 15%-30% of a water reducing agent, 5%-10% of a coagulant, 1%-3% of a nano oxide and 10%-50% of water. The prepared foaming agent has good foaming capacity and foaming stability, and foam holes formed in the foamed light soil are uniform in size and uniform in distribution. And the influence of moisture on the foamed light soil can be reduced, and the service life of the foamed light soil in a rainy humid and hot environment is prolonged.

Description

technical field [0001] The invention belongs to the field of foaming agents, in particular to a high-performance foam lightweight soil foaming agent. Background technique [0002] Foam lightweight soil is a kind of lightweight building material, which has the advantages of low density, high strength-to-weight ratio, and low thermal conductivity, and is widely used in building wall materials. However, in the rainy and humid environment in the south, the strength of the foam light soil will decrease after absorbing water, and the thermal insulation performance will decrease. Various harmful substances with water as the carrier will erode the interior of the concrete, and will reduce the cracks, hollowing and peeling of the foam light soil and the structural layer or waterproof layer. Therefore, the preparation of high-quality foam is very important for foaming light soil, and the performance of the foam depends on the foaming agent. A foaming agent with excellent performance ...
