Problems solved by technology

Most of the admixtures such as foaming agent and waterproofing agent on the market have a single performance, so we have to use a variety of single-performance admixtures for compound combination, which has always brought a series of compatibility troubles in debugging and operation.

Abstract

The invention discloses a waterproof foaming agent for foam concrete. The waterproof foaming agent is composed of the following raw materials by weight percentage: 3-9% of an air entraining agent component, 30-50% of a foaming component, 0.5-1.5% of a foam-stabilizing component, 2-8% of a waterproof component, and the balance water. According to the invention, various substances cooperate with each other, the waterproof foaming agent has strong foaming ability, under the circumstance of a dosage of 2%, the porosity of foam concrete can reach 90%; the foam stability is good, after placement at room temperature for 2h, the foam expansion rate is hardly reduced; and the hydrophobic effect is good, thus effectively improving the waterproof performance of foam concrete.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a foaming agent for waterproof foam concrete. Background technique [0002] Foamed concrete is widely used in various aspects such as building energy saving, sound-absorbing materials, and structural weight reduction due to its excellent properties such as heat insulation, sound absorption, and lightweight heat preservation. limit its application. Foaming agent is a key factor in the production of foamed concrete, and its performance directly determines the quality of foamed concrete. Most of the admixture products such as foaming agent and water repellent on the market have a single performance, so we have to use a variety of single-performance admixtures for compound combination, which has always brought a series of compatibility troubles in debugging and operation. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and ...
