Problems solved by technology

There are at least two defects in this method: one is that cooked rubber powder (also called "wallpaper powder") undergoes a corresponding modification reaction due to high water solubility and other requirements, which reduces the original viscoseness, resulting in the deterioration of the wallpaper. The adhesion between the wall and the wall is not enough; the second is that it is inconvenient to use
Another method is to use chemical glue alone (such as: polyvinyl alcohol and acrylic polymer, etc.), the disadvantage is that the cost is high
In addition, there are environmental protection problems in the production process of the above-mentioned wallpaper glue

Abstract

The invention discloses gelatinized starch wallpaper adhesive cement, and a preparation method and an application of the adhesive cement. The gelatinized starch wallpaper adhesive cement comprises the following components in parts by mass: 87-91 parts of water, 3-9 parts of starch, 0.5-2.5 parts of cellulose, and 1-3 parts of glycerol. The preparation method comprises the steps of gelatinizing the starch, adding the cellulose and the glycerol, and then preparing the gelatinized starch wallpaper adhesive cement. According to the preparation method, used raw materials are nontoxic and environment-friendly, production technology conditions are mild, no corrosion to equipment is caused, the production efficiency is high, and the obtained gelatinized starch wallpaper adhesive cement does not pollute an environment, and is good in property, low in cost and convenient to use.

Description

technical field [0001] The invention relates to the field of gelatinized starch technology and adhesives for architectural decoration, in particular to a gelatinized starch wallpaper glue and its preparation method and application. Background technique [0002] The current method of pasting wallpaper is usually: first use chemical glue (such as polyvinyl alcohol solution) as the primer to coat the surface of the wall evenly, and then use cooked rubber powder (such as etherified starch) to form an aqueous solution and apply it to the wallpaper. Then paste the bottom surface of the wallpaper to the wall with primer. If the edge of the wallpaper is warped, another chemical glue (such as acrylic polymer) attached to the product package should be used for recoating and adhesion. There are at least two defects in this method: one is that cooked rubber powder (also called "wallpaper powder") undergoes a corresponding modification reaction due to high water solubility and other requ...
