Abstract

The invention discloses a preparation method for a compound type foaming agent, relates to a preparation method for an additive for a building, in particular to a preparation method for a foaming agent added into concrete. The compound type foaming agent is compounded from an initial product, N,N'-dinitrosopentamethylamine (DPT), diglycol and lauryl alcohol. The compound type foaming agent is prepared on the basis of the original foaming agent, substances with excellent foaming properties are added into the foaming agent, and other additives are added to achieve the effects of increasing foams, stabilizing foams and regulating. The compound type foaming agent prepared by the preparation method is verified in practical production, and has the outstanding characteristics of being great in foaming amount, small in foam loss, small in strength effect and the like. The preparation method is simple to operate, is easy to control and is relatively high in yield.

Description

technical field [0001] The invention relates to a preparation method of an admixture for construction, in particular to a preparation method of a foaming agent added to concrete. Background technique [0002] In the construction process of concrete, various additives need to be added to change the properties of concrete such as performance, processing speed, and service strength. For concrete projects with special requirements, foaming agents need to be added during the construction process to improve the performance of concrete. The addition of foaming agent can effectively play the role of thermal insulation, sound absorption and sound insulation, and lightweight concrete. The foaming agent used in concrete also has many requirements in the process of use: [0003] 1. Thermal insulation: The use of foaming agent can effectively avoid the temperature loss of concrete. [0004] 2. Lightweight: The use of foaming agent can at least reduce the overall load of the building w...
