Abstract

The invention discloses a lightweight building material foaming agent and a preparation method thereof. The foaming agent comprises silicon carbide, potassium sodium feldspar powder and a sodium compound, wherein a mass ratio (or mass percentage ratio) of the silicon carbide to the potassium sodium feldspar powder to the sodium compound is (65-75%): (10-15%): (15-25%), and the mass percentage of potassium in the foaming agent is lower than the mass percentage of sodium. The foaming agent has a wide application range, is applicable to both foaming manufacturing of conventional lightweight building materials and microwave foaming manufacturing of lightweight building materials, and can effectively reduce the foaming manufacturing temperature of lightweight building materials and effectivelyreduce production cost.

Description

technical field [0001] The invention relates to the technical field of building material products, in particular to a lightweight building material foaming agent and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, the number of daily-use glass products and architectural glass that are discarded in the process of production and life is increasing day by day. According to statistics, the amount of waste glass in developed countries in Europe and the United States accounts for 4% to 8% of the total urban waste. In recent years, my country produces 10.4 million tons of waste glass every year. Waste glass substances have stable chemical properties, do not rot, burn, and cannot degrade. If waste glass is not treated and discharged along with other garbage, it will not only waste natural resources, but also cause harm to the environment. At present,...
