Abstract

The invention relates to a preparation method of an exterior wall heat-insulating coating capable of resisting pulverizing and falling, and belongs to the technical field of preparation of building materials. The preparation method comprises the following steps: grinding raw materials comprising coal ash rich in calcium, aluminum ions and siliceous salt, sandstone and imvite to obtain a sieving powder, cultivating oil-producing algae by taking waste water of a sugar refinery as a culture liquid, blending and fermenting the oil-producing algae, egg white and orange juice to obtain a fermented material, continuously fermenting the fermented material and the sieving powder for the second time, and finally preparing the exterior wall heat-insulating coating capable of resisting pulverizing andfalling by taking fermentation filter residues as a main material and cooperating with other auxiliary materials. The exterior wall heat-insulating coating capable of resisting pulverizing and falling has a high waterproof property, high durability and high adhesive strength, has low probability of pulverizing and falling and has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of an anti-powdering and falling-off exterior wall thermal insulation coating, which belongs to the technical field of building material preparation. Background technique [0002] In recent years, thermal insulation materials, especially thermal insulation coatings, have developed rapidly. The thermal insulation coating is used on the surface of the building to reduce its internal temperature, and it can also make the internal heat of the building difficult to lose quickly. Coating a layer of thermal insulation coating on the outer wall or roof of the building can effectively control the change of the indoor temperature and play a role in thermal insulation. The effect of heat. [0003] Insulation coatings combine the dual characteristics of coatings and insulation materials, and form an insulation layer with certain strength and elasticity after drying. Compared with traditional thermal insulation materi...
