Problems solved by technology

[0004] Flame-retardant glass flake cement is a flame-retardant upgraded version based on conventional glass flake cement. Compared with conventional glass flake cement, the mechanical properties and heat resistance of flame-retardant glass flake cement remain unchanged, but the oxygen index increases. Flame spreads slowly and is self-extinguishing

Abstract

The invention discloses flame-retardant glass flake mortar which comprises the following raw materials in parts by weight: 20-25 parts of flame-retardant epoxy vinyl ester resin, 10-15 parts of glass flake, 5-8 parts of curing agent, 10-13 parts of fire retardant, 5-8 parts of charring agent, 2-3 parts of fire-retardant fiber and 1-2 parts of adhesive. Compared with the conventional glass flake mortar, the mechanical properties and heat resistance of the flame-retardant glass flake mortar are not changed, but an oxygen index is increased; a rate of flame propagation is reduced; and the mortar has the self-extinguishment property.

Description

technical field [0001] The invention relates to the technical field of glass flake cement, in particular to a flame-retardant glass flake cement. Background technique [0002] The phenomenon that the glass phosphorus sheets used for anticorrosion in the anticorrosion project of the absorption tower of the power plant under construction or already built are burned frequently occurs. On the surface, it is caused by management reasons such as cross construction. The essential problem is that the glass flake cement has no flame retardant performance, the oxygen index is too low, and the burning speed is too fast. Once it is overfired, it has no self-extinguishing property, and it is easy to cause large-scale overfire and cause safety accidents. [0003] At present, vinyl ester resin is commonly used as the matrix resin of glass flake cement, which has excellent corrosion resistance and good processability. In addition to resin, glass flakes, curing agents, accelerators, pigmen...
