Description
Technical Field
The invention relates to the field of adhesive materials, in particular to environment-friendly glutinous rice glue for producing plates and a preparation method thereof.
Background
At present, people have higher and higher requirements on decoration materials, and the environmental protection performance of the decoration materials becomes one of the necessary conditions considered by many people. The wall paper is widely used by people due to good usability, environmental protection, decoration and other properties, the wall paper is usually adhered to the plate by using adhesive glue, and the common adhesive glue basically adopts a large amount of organic solvents such as formaldehyde and the like, so that great harm is caused to human body experience. The common glutinous rice flour is very environment-friendly and has certain adhesiveness, but as is well known, the pure glutinous rice flour has limited adhesiveness, is extremely easy to be corroded by bacteria and the like, and is mildewed, and the like, while a large amount of preservative is still harmful to human bodies, so that the original purpose of using the glutinous rice flour based on environment protection cannot be better reflected. For example, in a wallpaper mural glue with application number of 201410685799.2 and a preparation method thereof, the proportion of the wallpaper mural glue contains more bactericide components.
Disclosure of Invention
The invention aims to provide an environment-friendly glutinous rice glue for producing plates and a preparation method thereof, which are used for solving the technical problems that the ordinary adhesive glue basically adopts a large amount of organic solvents such as formaldehyde and the like, so that the human body can be greatly harmed, the ordinary glutinous rice glue is environment-friendly and has certain adhesiveness, but the pure glutinous rice glue has limited adhesiveness, is extremely easy to corrode by bacteria and the like, and mildew and the like occur, and the original purpose of using the glutinous rice glue based on environment friendliness cannot be achieved by adding a large amount of preservatives and the like.
In order to realize the purpose, the invention provides a preparation method of environment-friendly glutinous rice glue for producing plates, which comprises the following steps: 1) mixing the modifier, glacial acetic acid and absolute ethyl alcohol to prepare a mixed solution M1; 2) dropwise adding tetrabutyl titanate into the prepared mixed solution M1 under the condition that the pH value is 3-5, and mixing for 1-2h at the temperature of 60-100 ℃ to prepare a colloid M2; 3) mixing glutinous rice flour, colloid M2, didecyl dimethyl ammonium chloride, carrageenan, xanthan gum, locust bean gum, sodium carboxymethylcellulose and water to obtain the environment-friendly glutinous rice gum for producing the plate; wherein the modifier is selected from at least one of pentaerythritol, propylene glycol, octapentanediol and stearic acid.
Preferably, the glutinous rice flour is modified glutinous rice flour, and the modified glutinous rice flour is prepared by the following steps: A) mixing the raw material glutinous rice flour with water to obtain glutinous rice flour paste N1; B) adding a hydrochloric acid aqueous solution into the prepared glutinous rice flour paste, and then dropwise adding a potassium permanganate aqueous solution to prepare acidified glutinous rice flour emulsion N2; C) and dropwise adding a sodium hydroxide aqueous solution into the prepared glutinous rice flour emulsion N2, sequentially adding polyvinyl alcohol, casein, urea, bentonite and boric acid, and drying to obtain the modified glutinous rice flour.
Preferably, the step 3) further comprises adding a plant extract; wherein the plant extract is at least one of an extract of mugwort, an extract of camphor and an extract of aloe vera.
Preferably, the modifier is used in an amount of 0.5 to 2 parts by weight, the glacial acetic acid is used in an amount of 5 to 20 parts by weight, and the n-tetrabutyltitanate is used in an amount of 3 to 10 parts by weight, relative to 100 parts by weight of the anhydrous ethanol.
Preferably, in the step 3), the amount of the colloid M2 is 3 to 10 parts by weight, the amount of the didecyldimethylammonium chloride is 0.5 to 2 parts by weight, the amount of the carrageenan is 10 to 20 parts by weight, the amount of the xanthan gum is 10 to 20 parts by weight, the amount of the locust bean gum is 5 to 15 parts by weight, the amount of the sodium carboxymethylcellulose is 1 to 5 parts by weight, and the amount of the water is 600-1000 parts by weight, relative to 100 parts by weight of the glutinous rice flour.
Preferably, the amount of water used in step a) is 8 to 15g, the amount of aqueous hydrochloric acid solution is 0.5 to 1mL, the amount of aqueous potassium permanganate solution is 3 to 5mL, the amount of aqueous sodium hydroxide solution is 3 to 5mL, the amount of polyvinyl alcohol is 0.5 to 2g, the amount of casein is 1 to 3g, the amount of urea is 0.01 to 0.05g, the amount of bentonite is 0.1 to 1g, and the amount of boric acid is 0.01 to 0.02g, relative to 10g of the raw material glutinous rice flour.
