Technical Field

The invention relates to the technical field of glue solution, in particular to a preparation method of plant pulp glue solution for buildings.

Background

The putty (filling mud) is a decorative setting material for leveling the surface of a wall body, is thick paste paint and is an essential product before painting. Is applied on the primer or directly applied on the object to remove the defects of high and low unevenness on the surface of the object to be coated. The filler is mainly heavy calcium carbonate, talcum powder and the like, and common putty glue is usually added to improve the adhesiveness of the filler. Can fill the working surface with partial depression and can also scrape the whole surface. The traditional glue is mixed with double flying powder and flows, the construction is difficult, the filling property is poor, and 1-grade carcinogen asbestos can be introduced possibly to harm the bodies of constructors.

In order to solve the problems, a preparation method of plant pulp glue solution for buildings is provided.
