Abstract

The invention relates to a special seam splicing adhesive for a double-T plate. The special seam splicing adhesive comprises the following components 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 coal powder, 1-2 parts of simethicone, 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, 0.1-5 parts of a foaming agent and 3 parts of tetra(beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid)pentaerythritol ester. The special seam splicing adhesive disclosed by the invention has the advantage of high strength.

Description

technical field [0001] The invention relates to the technical field of fillers, in particular to a special joint glue for double T boards. 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 water resistance and aging resistance of the fillers currently used for ALC boards are poor and need to be improved. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a special joint glue for double T b...
