Abstract

The invention discloses xylogen-containing special environment-friendly vegetable glue for wallpaper and relates to a xylogen-containing adhesive. The adhesive comprises the following components in percentage by weight: 20-25 percent of xylogen, 50-60 percent of toluene diisocyanate, 10-12 percent of a tackifier and the balance of water, wherein the tackifier refers to rosin. The adhesive strength of the utilized xylogen is equivalent to that of a PF resin or an epoxy resin, and the synthesized xylogen can completely serve as a raw material of thermosetting polyurethane and also can serve as a production raw material of the adhesive. In order to improve the mechanical and thermal properties of the xylogen, the xylogen is modified by using the toluene diisocyanate.

Description

[0001] Technical field [0002] The present invention involves a special glue of wallpaper, especially a special plant environmentally friendly glue for wallpaper -containing wallpaper. [0003] Background technique [0004] During the decoration process, you will definitely come into contact with a lot of glue, such as floor glue, glass glue, wooden latex, wallpaper glue, carpet glue, and so on.Since formaldehyde and other chemical harmful substances are not good for our bodies, but in order to improve the viscosity, viscosity, and strength of glue.Taking natural materials as raw materials cannot meet all glue strength.The wallpaper is the lighter than other building materials, so the intensity required by the glue is also the lowest. The intensity of the glue of natural plants as the raw material is sufficient, and the cost of plant starch is relatively low. Invention content [0005] For the existing technology, the present invention provides a special plant environmentally f...
