Abstract

The invention relates to a composite early strength agent for a foam cement heat insulation plate and a preparation method thereof. The composite early strength agent for the foam cement heat insulation plate comprises an A component, a B component and water, wherein in parts by weight, the ratio of the B component to water is 1 to (10-15); the ratio of the B component and water to the A component is (1-2) to 1; the A component comprises the following components in percentage by weight: 38-45% of accelerator, 1.5-3.0% of metal salt and 53-60% of water; the B component comprises the following components in percentage by weight: any one of 60-70% of sodium chloride or 60-70% of sodium sulfate or 60-70% of aluminum chloride, 25-35% of sodium nitrite and 3-7% of surfactant. After the A component and the B component are compounded, the synergetic effect can be realized, foam cement can be set within 20min to several hours, the initial setting time and the final setting time of the foam cement are shortened, the late strength rises rapidly and the production efficiency is improved.

Description

technical field [0001] The invention discloses a composite early-strength agent for foamed cement insulation boards and a preparation method thereof, which is used in external wall insulation systems and belongs to the field of building materials. Background technique [0002] Among the many forms of energy consumption, the proportion of building energy consumption in my country's total energy consumption is increasing year by year, for example, it has risen from 10% in the late 1970s to 27.6% now; and the heating energy of residential buildings in my country consumption is three times that of developed countries. Especially in recent years, my country's building energy consumption has continued to grow with the improvement of urbanization rate, economic development, people's income and living standards. In recent years, with the continuous emergence of new materials and the continuous improvement of people's requirements for building energy conservation, external wall insul...
