Abstract

The invention relates to a building material and a preparation method thereof, in particular to novel insulating waterproof foaming agent and a preparation method thereof. The novel insulating waterproof foaming agent comprises the following components by weight percentage of the total weight of the novel insulating waterproof foaming agent: 10 to 15 percent of rosin, 2.5 to 3.75 percent of caustic soda, 0.001 to 0.003 percent of citric acid, 0.05 to 0.1 percent of SM efficient water-reducing agent, 0.5 to 1 percent of silica powder, 35 to 47 percent of rubber powder, and 35 to 50 percent of water. The preparation method for the novel insulating waterproof foaming agent comprises the following steps: firstly mixing, stirring and heating the rosin and the caustic soda; then dissolving the SM efficient water-reducing agent, the citric acid and the silica powder into the water, heating and insulating the mixture; and mixing the two mixtures into a heating container, adding water into the mixtures and stirring the mixtures, and adding the rubber powder with required amount into the twice mixtures and stirring the mixtures. Compared with the prior art, the method adopting compound foaming improves quality of the foam greatly, the inner wall of a bubble formed by foaming can form a layer of extremely thin high-molecular crystal glue film with waterproof function, and mortar added with the foaming agent also has better heat-insulating property.

Description

technical field [0001] The invention relates to a building material and a preparation method thereof, in particular to a novel thermal insulation and waterproof foaming agent and a preparation method thereof. technical background [0002] Concrete is one of the most used construction materials today. The foaming agent is introduced into the concrete to generate tiny uniform air bubbles inside the concrete, which can form lightweight and good thermal insulation foam concrete, which is used for the insulation layer of roofs, non-load-bearing walls and thermal pipes. With the increasingly widespread application of foam concrete in engineering, in-depth research on foaming agents and foam concrete provides a basis for the construction industry. But the performance of the thermal insulation waterproof foaming agent on the market is not very satisfactory. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new thermal ...
