Abstract

The invention discloses a starch wallpaper adhesive and a preparation method thereof. A larger amount of wallpaper adhesive in the current market is polyvinyl acetal adhesive and comprises the main components of water, polyvinyl alcohol and formaldehyde, wherein the formaldehyde does greater harm to a human body. The starch wallpaper adhesive comprises the following raw materials: 20-30 parts of starch, 10-20 parts of sodium carboxymethyl starch, 80-150 parts of water, 0.04-0.24 parts of hydrogen peroxide, 2-9 parts of calcium carbonate, 0.4-1.5 parts of citric acid and 0.02-0.09 parts of sodium benzoate. The starch wallpaper adhesive takes starch as the main raw material, and after a variety of reactions, has the advantages of strong adhesion, high acid and alkali resistance, anti-freezing property, moisture prevention and convenience for use; and wallpaper pasted by the starch wallpaper adhesive is good in film formation, soft in film, difficult to age and stable in performance.

Description

technical field [0001] The invention relates to a starch wallpaper adhesive and a preparation method thereof, belonging to the technical field of daily chemical industry. Background technique [0002] In interior decoration, wallpaper is widely used, and the quality of wallpaper paste has a lot to do with the adhesive used. The most widely used wallpaper adhesive on the market is the polyvinyl acetal adhesive, which was born in the 1980s. The technology is simple, and the main components are water, polyvinyl alcohol, and formaldehyde. However, modern people have paid more and more attention to the harm of formaldehyde to the human body during the decoration process. After using formaldehyde-containing wallpaper adhesives, it takes a long time for the volatilization and release of formaldehyde, which seriously endangers people's health; and this The wallpaper-like adhesive has weak adhesion and poor durability, and the wallpaper will fall off after a long time. Therefore, i...
