Abstract

The invention discloses a rapid condensation high-strength flame retardant thermal insulation material and a preparation method thereof. The rapid condensation high-strength flame retardant thermal insulation material is prepared from the following raw materials in percentage by weight: 5-55% of metallic oxide, 5-55% of phosphate, 1-10% of additive, 0.5-5% of fiber material, 0.5-50 of thermal insulation component and 5-50% of water. The rapid condensation high-strength flame retardant thermal insulation material is high in condensation speed; when the material is placed for 4 hours at a normal temperature, the compression strength of the thermal insulation material can reach 20MPa, and the breaking strength can reach 3.5MPa; and when the material is placed for 8 days at a normal temperature, the compression strength of the thermal insulation material can reach 60MPa, and the breaking strength can reach 10MPa. The thermal insulation material has good compatibility with concrete, cement and the like and high cold resistance and can be used under low temperature conditions of 0-10 DEG C. The rapid condensation high-strength flame retardant thermal insulation material can be directly sprayed to walls, roadway walls, tunnel walls and the like or is poured into a grinding tool with appointed size and shape and is compacted and shaped by vibration.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fast-setting high-strength flame-retardant thermal insulation material and a preparation method thereof. Background technique [0002] At present, the commonly used cement polystyrene particle insulation materials for building walls, coal mine roadways and tunnels mainly have the following disadvantages: [0003] 1. Cement is used as adhesive, which has weak cohesive force, poor adhesion to walls, coal mine roadways, tunnels, etc., poor durability, and easy to fall off. [0004] 2. The compressive strength and flexural strength of the insulation material are low, and it is easy to break and fall off under the action of shear force and pressure. [0005] 3. The cost is high. Due to the low strength of the insulation material itself, it is necessary to apply polymer anti-crack mortar between the building walls, coal mine roadways, tunnels and insulation materials, and th...
