Abstract

The invention discloses an inorganic heat-insulating fireproof plate and a manufacturing method thereof. The inorganic heat-insulating fireproof plate mainly is prepared by mixing the following components in percentage by weight: 10 to 20 percent of expanded vitrified ball, 8 to 15 percent of bauxite cement, 15 to 25 percent of ordinary Portland cement, 10 to 18 percent of hemihydrate gypsum, 0.2 to 0.5 percent of macromolecular polymer rubber powder, 0.05 to 0.1 percent of polypropylene fiber, 0.05 to 0.1 percent of organic silicon water repellent, 0.25 to 0.5 percent of cellulose ether and 45 to 60 percent of water. The heat-insulating fireproof plate product has excellent heat-insulating property, high strength and high dimensional stability.

Description

[0001] technical field [0002] The invention relates to the field of building materials, in particular to a heat-insulating and fire-proof board with good thermal insulation and fire-proof performance, and the invention also relates to a manufacturing method of the heat-insulating and fire-proof board. [0003] Background technique [0004] With the innovation of wall materials and the implementation of building energy-saving policies in my country, the development and application of energy-saving building materials have been widely valued. On March 14, 2011, the General Fire Administration of the Ministry of Public Security issued the "Notice on Further Clarifying Relevant Requirements for Fire Supervision and Management of Civil Building External Thermal Insulation Materials" Gongxiao [2011] No. Materials with performance class A. For this reason, the research and production of inorganic thermal insulation materials are becoming increasingly urgent, especially the resea...
