Light compound-insulation fireproofing dry-mixed mortar and preparation method thereof

Abstract

The invention discloses light compound-insulation fireproofing dry-mixed mortar and a preparation method thereof. The dry-mixed mortar is prepared from the following raw materials in parts by weight: 1-3 parts of wood fiber, 3-6 parts of hydroxypropyl methyl cellulose, 3-7 parts of polypropylene short fiber, 5-8 parts of resin type redispersible rubber power, 80-120 parts of coarse whiting powder, 80-120 parts of slaked lime, 80-120 parts of coal ash, 600-800 parts of cement, 300-500 parts of glass beads, 1-4 parts of green syrup, 3-6 parts of lignosulfonate, 5-6 part of calcium formate, 1-2.5 parts of a high-efficiency slushing agent, 1-3 parts of a thixotropic lubricating agent, 3-5 parts of a concrete water-proofing agent and 0.1-0.4 part of an air entraining agent. The preparation method comprises the steps of preparing according to a certain feeding sequence, and uniformly mixing at the normal pressure and temperature and a stirring speed of 30-100 revolutions per minute. The preparation method has the advantages that the defect that an insulation material of a normal wall cannot be automatically maintained is solved, the absorption and discharging of the moisture are automatically balanced, the problems of cracking, hollowing, falling and the like occurring after the construction are solved, complex working procedures for utilizing gridding cloth and the like are omitted, the construction difficulty under the normal temperature is low, and the energy conservation and environmental protection requirements are met.

Description

technical field [0001] The invention relates to a material used for walls, in particular to a lightweight composite heat-preservation and fire-proof dry powder mortar and a preparation method thereof. Background technique [0002] At present, the general wall insulation materials mainly use rubber powder polyurethane and cement as the coagulation material, and the aggregates mainly use silicon-calcium board, polystyrene board, extruded board organic materials or traditional inorganic materials. The existing general wall insulation materials There are the following disadvantages: no fire protection, low compressive strength, large deformation coefficient, poor safety and stability, easy to crack, low thermal insulation coefficient, no energy saving, easy to cause environmental pollution, difficult construction, and high cost. It does not meet the requirements of fire prevention, energy saving, environmental protection, easy construction and low cost. Contents of the inventi...
