Abstract

The invention discloses a flame-retardant thermal insulation mortar for building construction, comprising the following raw materials in parts by weight: 80-90 parts of Portland cement, 8-12 parts of self-extinguishing polystyrene particles, and 15-20 parts of flame retardant additives parts, 10-12 parts of ceramic microbeads, 4-5 parts of reinforcing fillers, 1.6-2 parts of rubber powder, 0.8-1 parts of auxiliary agents, and 160-180 parts of tap water; the invention also discloses a preparation method of the thermal insulation mortar. In the present invention, a self-made flame retardant additive is added into the mortar, and the flame retardant additive is a kind of compound, which can exert a flame retardant effect in the condensed phase and the gas phase, and endow the mortar with good flame retardant performance; , the rubber powder can not only promote the dispersion, but also can block the capillaries inside the mortar and reduce the dry shrinkage; through the auxiliary preparation of other additives, reinforcing fillers, etc., the mortar has good mechanical properties; the mortar prepared by the present invention has good resistance. Combustible performance, suitable for building exterior walls.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a flame-retardant thermal insulation mortar for building construction and a preparation method thereof. Background technique [0002] In order to effectively prevent fires, it is clarified that the building's external thermal insulation materials use materials with a combustion performance of Class A. Most organic thermal insulation materials, such as expanded polystyrene board, extruded polystyrene board, and foamed phenolic board, cannot achieve Class A combustion performance without fire protection treatment. The combustion performance of inorganic thermal insulation materials reaches Class A (non-combustible), and inorganic thermal insulation materials used in exterior wall thermal insulation are a new type of energy-saving and environmentally friendly materials. This inorganic thermal insulation material is soundproof, fireproof, thermal insulation, a...
