AI Technical Summary

Problems solved by technology

[0003] The existing cement foam fireproof insulation board, because the bubbles in the foaming process are not dense enough, the bubbles are very easy to collapse due to the continuous pushing and impact of the mold box during the continuous operation of the assembly line, resulting in the production of insulation boards with air bubbles The collapse of the body is serious, the scrap rate is high, the production cost is high, and the production process is not easy to control, which seriously affects the production efficiency and product qualification rate

The raw materials of the composition are easy to obtain, the process is simple and convenient, bubble bodies are formed rapidly and are not prone to collapse, the preparation method is suitable for large-scale assembly line work production, the production efficiency is greatly improved, and good economical benefits are achieved.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a foamed cement grade A fireproof insulation board, a composition for making it and a preparation method thereof. Background technique [0002] As the country pays more and more attention to building energy-saving technology for roof and wall insulation, various types of external wall insulation materials continue to appear in the market. However, currently commonly used insulation materials such as polystyrene board, extruded board and foamed phenolic resin have disadvantages such as flammability, aging, high cost and short service life. Especially in recent years, fire accidents ignited by building exterior wall insulation materials have occurred frequently, and the fire safety of building exterior wall insulation systems has been valued by relevant national ministries and commissions. [0003] The existing cement foam fireproof insulation board, because the bubbles in the fo...
