Problems solved by technology

[0003] At present, there is no foaming material specially designed for the preparation of sound-absorbing foamed concrete products on the market. The sound-absorbing effect of sound-absorbing foamed concrete products prepared by ordinary foaming materials is not ideal. What is more serious is that some foaming agents are still It affects other properties of sound-absorbing products, such as strength, etc. Many of the above factors restrict the further promotion and popularization of sound-absorbing foam concrete products

Embodiment 1

[0025] According to the mass ratio, it is fatty alcohol polyoxyethylene ether sodium sulfate (AES) 5-7%, sodium dodecyl sulfate (K12) 1%, sodium dodecylbenzenesulfonate (DBS) 3.5%, tea saponin 0.15% %, disodium ethylenediaminetetraacetic acid (EDTA) 2%, modified nano-bentonite 1.5% and the rest of the water to prepare raw materials. First add fatty alcohol polyoxyethylene ether sodium sulfate (AES) into an appropriate amount of water, heat and stir evenly in a water bath at a temperature of 30°C-50°C; then add sodium lauryl sulfate (K12), dodecylbenzene Sodium sulfonate (DBS), continue to stir until all materials are completely dissolved, and finally add tea saponin, disodium ethylenediaminetetraacetic acid (EDTA), modified nano-bentonite and the rest of the water.

Embodiment 2

[0027] According to the mass ratio, it is fatty alcohol polyoxyethylene ether sodium sulfate (AES) 5.5-7.5%, sodium dodecyl sulfate (K12) 2%, sodium dodecylbenzenesulfonate (DBS) 2.5%, tea saponin 0.3 %, disodium ethylenediaminetetraacetic acid (EDTA) 2.5%, modified nano-bentonite 2% and the rest of the water to prepare raw materials. First add fatty alcohol polyoxyethylene ether sodium sulfate (AES) into an appropriate amount of water, heat and stir evenly in a water bath at a temperature of 30°C-50°C; then add sodium lauryl sulfate (K12), dodecylbenzene Sodium sulfonate (DBS), continue to stir until all materials are completely dissolved, and finally add tea saponin, disodium ethylenediaminetetraacetic acid (EDTA), modified nano-bentonite and the rest of the water.

Embodiment 3

[0029] According to the mass ratio, it is fatty alcohol polyoxyethylene ether sodium sulfate (AES) 7-8%, sodium dodecyl sulfate (K12) 3%, sodium dodecylbenzenesulfonate (DBS) 1.5%, tea saponin 0.45% %, disodium ethylenediaminetetraacetic acid (EDTA) 3%, modified nano-bentonite 2.5% and the rest of the water to prepare raw materials. First add fatty alcohol polyoxyethylene ether sodium sulfate (AES) into an appropriate amount of water, heat and stir evenly in a water bath at a temperature of 30°C-50°C; then add sodium lauryl sulfate (K12), dodecylbenzene Sodium sulfonate (DBS), continue to stir until all materials are completely dissolved, and finally add tea saponin, disodium ethylenediaminetetraacetic acid (EDTA), modified nano-bentonite and the rest of the water.

Abstract

The invention relates to a foaming agent for a sound absorption foam concrete product and a preparation method for the foaming agent. The foaming agent comprises the following components in percentage by mass: 5 to 10 percent of fatty alcohol-polyoxyethylene ether sodium sulfate, 1 to 5 percent of lauryl sodium sulfate, 1 to 5 percent of sodium dodecyl benzene sulfonate, 0.1 to 2 percent of tea saponin, 1 to 5 percent of disodium ethylene diamine tetraacetate, 1 to 5 percent of modified nanometer bentonite and the balance of water. The foaming agent special for sound absorption foam concrete is stable in performance, high in foaming times and high in workability with concrete base materials, and has an adjustable pore structure.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a foaming agent for sound-absorbing foam concrete products and a preparation method thereof. Background technique [0002] At present, urbanization is in full swing, with the rapid development of various means of transportation and the densification of population, a series of noise problems resulting from this have seriously affected the normal life of human beings. At the same time, sound-absorbing and sound-insulating materials Also facing new development opportunities, sound-absorbing products of various materials have sprung up like mushrooms after rain, and sound-absorbing foam concrete products are the best of these materials. [0003] At present, there is no foaming material specially designed for the preparation of sound-absorbing foamed concrete products on the market. The sound-absorbing effect of sound-absorbing foamed concrete products prepared by ordinary foaming materials is not i...
