Problems solved by technology

[0003] The purpose of the present invention is to provide environmentally friendly glutinous rice glue and its preparation method for board production, to solve the problem that organic solvents such as formaldehyde will be used in large quantities in general adhesive glues, which will cause great harm to the human body. Although general glutinous rice glue is environmentally friendly and has Certain adhesiveness, but pure glutinous rice glue not only has limited adhesion, but also is easily corroded by bacteria, mildew, etc., and a large amount of preservatives can not be used. question

preparation example Construction

[0018] The invention provides a kind of preparation method of environment-friendly glutinous rice glue for plate production, wherein, comprise the following steps:

[0019] 1) Mix modifier, glacial acetic acid and absolute ethanol to prepare mixed solution M1;

[0020] 2) Under the condition of pH 3-5, add n-tetrabutyl titanate dropwise to the mixed solution M1 prepared above, and mix at a temperature of 60-100°C for 1-2 hours to obtain colloid M2 ;

[0021] 3) mixing glutinous rice flour, colloid M2, didecyldimethylammonium chloride, carrageenan, xanthan gum, locust bean gum, sodium carboxymethylcellulose and water to prepare environmentally friendly glutinous rice glue for board production; ,

[0022] The modifier is selected from at least one of pentaerythritol, propylene glycol, octapentyl glycol and stearic acid.

[0023] The present invention has the following beneficial effects: the present invention selects at least one of pentaerythritol, propylene glycol, octapent...

Embodiment 1

[0040] 1) Mix 0.5g of pentaerythritol, 5g of glacial acetic acid and 100g of absolute ethanol to prepare a mixed solution M1;

[0041] 2) Add concentrated hydrochloric acid to the above mixed solution M1 to adjust the pH to 3, add 3 g of n-tetrabutyl titanate dropwise to the above mixed solution M1 at a rate of 80 drops / min, and place in a water bath at a temperature of 60°C Mixed for 1 hour under the condition to obtain colloid M2;

[0042] 3) Extract 100g modified glutinous rice flour, 3g colloid M2, 0.5g didecyldimethylammonium chloride, 10g carrageenan, 10g xanthan gum, 5g locust bean gum, 1g carboxymethylcellulose sodium, 30g mugwort leaves The mixture was mixed with 600g of water by ultrasonic vibration for 10min to obtain the environmentally friendly glutinous rice glue A1 for board production.

Embodiment 2

[0044] 1) Mix 2g of propylene glycol, 20g of glacial acetic acid and 100g of absolute ethanol to prepare a mixed liquid M1;

[0045] 2) Add concentrated hydrochloric acid to the above mixed solution M1 to adjust the pH to 5, add 10 g of n-tetrabutyl titanate dropwise to the above prepared mixed solution M1 at a rate of 200 drops / min, and place in a water bath at a temperature of 100°C Mixed for 2 hours under the same conditions to obtain colloid M2;

[0046] 3) 100g modified glutinous rice flour, 10g colloid M2, 2g didecyldimethylammonium chloride, 20g carrageenan, 20g xanthan gum, 15g locust bean gum, 5g sodium carboxymethylcellulose, 20g camphor extract Mix with 1000g of water for 15 minutes by ultrasonic vibration to obtain the environmentally friendly glutinous rice glue A2 for board production.

Abstract

The present invention provides an environment-friendly glutinous-rice gum for plate production and a preparation method of the gum. The method comprises the following steps: 1) mixing a modifier, glacial acetic acid and absolute ethanol to prepare a mixed solution M1; 2) under a pH condition of 3-5, dropwise adding tetrabutyl titanate into the above prepared mixture M1, and performing mixing for 1-2 h at a temperature of 60-100 DEG C to obtain a colloid M2; and 3) mixing glutinous rice flour, the colloid M2, didecyl dimethyl ammonium chloride, carrageenan, xanthan gum, locust bean gum, sodiumcarboxymethylcellulose and water to prepare the environment-friendly glutinous-rice gum for sheet production, wherein the modifier is at least one selected from of pentaerythritol, propylene glycol, neopentyl glycol and stearic acid. The glutinuous-rice gum achieves advantages of environmental protection, high adhesion, corrosion resistance and the like.

Description

technical field [0001] The invention relates to the field of adhesive materials, in particular to an environmentally friendly glutinous rice glue for board production and a preparation method thereof. Background technique [0002] At present, people have higher and higher requirements for decoration materials, and the environmental protection performance of decoration materials has become one of the necessary conditions for many people to consider. Plates have gradually replaced traditional wall powder, paint and other materials, and wallpaper, etc. are more and more widely used by people because of their good usability, environmental protection and decorative properties. Adhesive glue is used for adhesion. General adhesive glue basically uses a large amount of organic solvents such as formaldehyde, which will cause great harm to the human body. Ordinary glutinous rice flour is very environmentally friendly and has a certain degree of adhesion, but as we all know, pure glut...
