Abstract

The invention provides a foaming agent, relates to a building admixture, particularly relates to a foaming agent added into concrete and also relates to a preparation method of the foaming agent. A compound type foaming agent is prepared on the basis of the original foaming agent; several types of materials with excellent foaming performance are added into the foaming agent; then other admixturesare added into the foaming agent, so that the effects of increasing foam, stabilizing foam and adjusting are achieved; the compound type foaming agent prepared by the invention has been verified in the actual production; the compound type foaming agent has the prominent properties of high foaming capacity, low foam loss, low influence on strength and the like.

Description

technical field [0001] The invention relates to an admixture for construction, in particular to a foaming agent added to concrete. The invention also relates to a process for the preparation of this blowing agent. 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 reduc...
