Abstract

The invention relates to a waterproof abutted seam filling agent for ALC, wherein the waterproof abutted seam filling agent comprises the following components in parts by weight: 150-250 parts of polypropylene oxide glycol, 100-150 parts of MDI, 20-40 parts of propane and butane, 10-20 parts of ethylene glycol dimethyl ether, 70-100 parts of superfine pulverized coal, 1-2 parts of dimethyl silicone oil, 0.5-1.5 parts of dibutyltin dilaurate, 10-20 parts of polysilsesquioxane, 10-20 parts of hollow glass micro-beads, 1-3 parts of bimorpholine and 0.1-5 part of foaming agent. The waterproof abutted seam filling agent has the advantage of high strength.

Description

technical field [0001] The invention relates to the technical field of fillers, in particular to a waterproof joint filler for ALC. Background technique [0002] ALC board is the abbreviation of autoclaved lightweight concrete, a kind of high-performance autoclaved aerated concrete. ALC board is a porous concrete forming board made of fly ash, cement, lime, etc. as the main raw materials and cured by high-pressure steam. ALC board can be used not only as wall material, but also as roof panel. It is a new type of building material with superior performance. However, during the use of ALC boards, there will be gaps between two adjacent ALC boards, and fillers need to be used. However, the strength and flame retardancy of the fillers currently used for ALC boards are low and need to be improved. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a waterproof joint filler for ALC, which has the ...
