Rosin foaming agent

Abstract

The invention relates to the field of building materials, particularly a rosin foaming agent. The rosin foaming agent comprises the following raw materials in parts by weight: 30-40 parts of carbolic acid, 2-5 parts of sulfuric acid, 3-6 parts of sodium hydroxide and 60-75 parts of rosin powder. The rosin foaming agent is prepared from the steps of: pouring the rosin powder, carbolic acid and sulfuric acid into a flask with stirring; slowly heating and stirring after addition, wherein the temperature is controlled between 70 DEG C and 80 DEG C; keeping warm for 6 hours with stirring; then adding a sodium hydroxide solution; heating the mixture for 2 hours, wherein the temperature is close to 100 DEG C; and filling the solution while the solution is hot in a storer to obtain the rosin foaming agent. The rosin foaming agent provided by the invention is simple in formula and easily available in raw materials, and is mainly used for preparing foam concrete or air-added concrete bricks. The product provided by the invention has uniform foaming, and solves the problem that the marketed foaming agent is poor in a dispersing effect and with non-uniform foaming.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a rosin foaming agent. Background technique [0002] With the promotion of the national wall reform policy, new environmentally friendly wall materials and energy-saving building materials have attracted more and more attention from users, and aerated concrete blocks and panels are the most popular among the new wall materials. Aerated concrete blocks and slabs are widely used in non-load-bearing walls of ordinary houses or frame buildings due to their increasingly significant role in saving land and energy resources and protecting the ecological environment. Ordinary aerated concrete is made by grinding fly ash or silica sand with water to make a slurry, adding powdered lime, appropriate amount of cement, gypsum and aluminum powder, passing in steam, stirring and injecting into the mold frame, and then statically foaming and solidifying. Cut into blocks or plates of various sp...
