Abstract

The invention provides a waterborne polyurethane wallpaper glue comprising the following raw material components in parts by weight: 100 parts of waterborne polyurethane resin; 0.1-0.5 part of a wetting levelling agent; 0.1-1.0 part of a mildew preventive; and 0.2-1.0 part of a thickener. The obtained wallpaper glue is simple in construction process, a layer of base film (having an alkali-resistant sealing effect) is not required to be brushed on a wall body before pasting, and the waterborne polyurethane wallpaper glue is directly brushed on wallpaper and then is pasted on the wall body; the waterborne polyurethane wallpaper glue has excellent alkali resistance; a prepared waterborne polyurethane wallpaper glue film is not abnormal when soaked in a 10% sodium hydroxide solution for 72 h and can resist hydrolysis for five years or more; the waterborne polyurethane wallpaper glue has the advantages of stable storage, safety and environmental protection, no release of formaldehyde, and high product pasting fastness, and has the tear strength after pasting and drying reaching 40 N or more; and the waterborne polyurethane wallpaper glue is convenient to construct, has no need for blending, can be directly brushed, and overcomes the disadvantage that a starch glue and a glutinous rice glue are slow to dry when applied in winter.

Description

technical field [0001] The invention relates to the field of adhesives, and specifically discloses a water-based polyurethane wallpaper adhesive. Background technique [0002] Wallpaper glue is mainly used to paste wallpaper and wall covering. It is a kind of adhesive commonly used in the building materials decoration industry. It is the most basic function to stick to wallpaper and ensure the service life of wallpaper. Adhesives for wallpaper in the current market include: starch adhesives, cellulose adhesives and chemical adhesives. Starch adhesives are unstable in storage, slow in drying and prone to changes in performance. Cellulose adhesive is made of high-quality long-staple cotton fiber, and affected by its raw material, its cost is high and expensive. The adhesive ability used alone cannot meet the adhesive requirements of wallpaper, and it needs to be modified with starch or mixed with chemical glue. [0003] Most of the modified starches used for wallpaper glue ...
