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

A kind of starch wallpaper tackiness agent and preparation method thereof

Technical field

What the present invention relates to is a kind of starch wallpaper tackiness agent and preparation method thereof, belongs to the daily-use chemical industry technical field.

Background technology

In interior decoration, the application of wallpaper is more widely, and the quality that wallpaper is pasted has very big relation with employed tackiness agent.The wallpaper tackiness agent of large usage quantity is the polyvinyl acetal tackiness agent of being born in the eighties on the market at present, and technology is simple, and staple is water, Z 150PH, formaldehyde.But the modern has more and more noticed in the fitment process formaldehyde to the harm of human body, used the wallpaper tackiness agent that contains formaldehyde after, the volatilization release of formaldehyde needs considerable time of experience, serious harm people's health; And a little less than this type of wallpaper tackiness agent bounding force, poor durability, the time has been grown the wallpaper obscission will take place.Therefore, seek a kind of safety and environmental protection, cohesive force is strong, the wallpaper tackiness agent that weather resistance is high is exactly necessary.

Summary of the invention

The object of the invention just provides a kind of environmental protection, does not contain formaldehyde, and cohesive force is strong; Weather resistance is high, raw material is simple, and the starch wallpaper tackiness agent of wide material sources overcomes traditional wallpaper adhesive contamination environment; To the toxic elements in human body evil, cohesive force is poor, the shortcoming of poor durability.

The foregoing invention purpose realizes through following technical scheme, and a kind of starch wallpaper tackiness agent mainly is made up of the following weight parts raw material:

Starch 20-30 part, sodium starch glycolate 10-20 part, water 80-150 part, ydrogen peroxide 50 0.04-0.24 part, lime carbonate 2-9 part, Hydrocerol A 0.4-1.5 part, Sodium Benzoate 0.02-0.09 part;

Said starch is yam starch, tapioca(flour), W-Gum, Starch rice, wheat starch;

Said sodium starch glycolate, ydrogen peroxide 50, lime carbonate, Hydrocerol A and Sodium Benzoate are commercially available industrial commodity;

Above-mentioned raw materials is by art method preparation down;

(1) 10-20 weight part sodium starch glycolate is added in the 80-150 weight parts water, fully stirring after the swelling obtains the sodium starch glycolate solution for later use;

(2) 20-30 weight part starch is slowly added in the CMS sodium solution, the limit edged is stirred to stir and obtains the mixing starch solution for later use;

(3) 0.04-0.24 weight part ydrogen peroxide 50 is added in the mixing starch solution, stirred 30-50 minute down, obtain ydrogen peroxide 50 mixing starch solution for later use in 40-70 ℃ of environment;

(4) 2-9 weight part lime carbonate, 0.4-1.5 weight part Hydrocerol A and 0.02-0.09 weight part Sodium Benzoate are added in the ydrogen peroxide 50 mixing starch solution, stirring promptly gets.

Take the present invention of above-mentioned measure, adopted starch,, have the advantage that bounding force is strong, resistance to acids and bases is high, antifreeze, moistureproof, easy to use through after the various reactions as main raw material; Use the wallpaper of putting up behind the present invention, good film-forming property, soft, difficult aging, the stable performance of film property.As staple, the traditional wallpaper tackiness agent that contains the formaldehyde composition with tradition is compared, and does not contain harmful chemical substance with the natural phant goods in the present invention, and therefore environment-protecting asepsis, non-stimulated flavor can reach the environmental protection safe requirement.
