The battens are transversely arranged side by side, and every two adjacent battens are spliced through strengthened cloth layers. The building template body comprises a first surface and a second surface opposite to the first surface. The first surface is sequentially provided with a first composite layer and a first protective layer, and the second surface is sequentially provided with a second composite layer and a second protective layer. The protective layers of the building template can cover glass fibers exposed when glass steel is damaged and can prevent the double hands of a worker conducting separation from being scratched. Meanwhile, the protective layers greatly improve the degree of finish of the surfaces of the building template.

The invention belongs to the technical field of adhesives, and particularly relates to a preparation method of a flame-retardant and waterproof adhesive for a corrugated carton. The preparation methodspecifically comprises the following steps: (1) an organic silicon modified emulsion is prepared; (2) a white prepolymer emulsion is prepared; (3) an acrylic modified flame-retardant organic siliconemulsion is prepared; and (4) 110-120 parts of the acrylic modified flame-retardant organic silicon emulsion is put into a high-speed mixer, 1.5-2.3 parts of carnallite powder, 24-27 parts of polyhalite powder and 5-7 parts of a flame retardant are added, even stirring and mixing are conducted, and then the flame-retardant and waterproof adhesive is obtained. The prepared adhesive is transparent,high in adhesion and good in stability, water-based adhesive bonding, quick drying, and acid and alkali resistance are achieved, no organic solvent is contained, the poisonless, tasteless, non-combustible, environment-friendly and pollution-free effects are achieved, and pollution-free production can be achieved. The flame-retardant and waterproof adhesive is suitable for the carton not coated andpolished, and the corrugated carton is protected very well.
