Problems solved by technology

[0002] At present, most of the environmentally friendly adhesives for wallpaper are liquid starch glue or glutinous rice glue, but liquid starch glue has poor storage stability, because the water content reaches 80%-90 %, liquid starch glue brings a lot of inconvenience to packaging, storage and transportation, and at the same time increases storage and transportation costs. What is more important is that the liquid starch glue will cause the binder to fail if it freezes during winter transportation and storage.

Embodiment 1

[0023] Proportion of puffed starch solid powder glue: puffed glutinous rice starch 85 kg, xanthan gum 12 kg, stearic acid 200 g, alum 500 g, calcium chloride 800 g, carboxymethyl cellulose sodium CMC 200 g, 2,4 , 50 grams of 5,6-tetrachloro-1,3-phthalonitrile, 200 grams of sodium benzoate.

[0024] Preparation method: first dissolve 500 grams of alum in 8 kg of hot water at 50°C to 60°C, then spray the alum solution on 85 kg of glutinous rice to soak and absorb it; put the water-containing glutinous rice into an extruder for puffing For processing, the puffing temperature is controlled at 180° C., and the puffing pressure is 0.7 MPa; the puffed glutinous rice particles are sent to a pulverizer for pulverization, and sieved with 200 meshes to become puffed starch. The water content of starch raw materials has a direct impact on the puffing process. If the water content is low, there will not be enough water vapor generated during puffing, and the starch tissue will not be a...

Embodiment 2

[0028] Proportion of puffed starch solid powder glue: puffed glutinous rice starch 80 kg, pregelatinized starch 18 kg, erucamide 200 g, alum 500 g, bentonite 1 kg, carboxymethyl cellulose sodium CMC 200 g, methyl isothiazole Linone 50 grams, sodium benzoate 200 grams.

[0029] Preparation method: first dissolve 500 grams of alum in 8 kg of hot water at 50°C-60°C, spray the alum solution on 80 kg of glutinous rice to make it soak and absorb; put the water-containing glutinous rice into an extruder for puffing treatment , the puffing temperature is controlled at 190°C, and the puffing pressure is 0.7MPa; the puffed glutinous rice particles are sent to a pulverizer for crushing, and sieved with 200 meshes to become puffed starch; puffed starch, pregelatinized starch, erucamide, Bentonite, CMC, sodium benzoate and methylisothiazolinone etc. are mixed in a high-speed mixer according to the ratio, and then dried and packaged.

Embodiment 3

[0032] Proportion of puffed starch solid powder glue: puffed glutinous rice starch 40 kg, puffed potato starch 40 kg, xanthan gum 28 kg, stearic acid amide 300 g, alum 400 g, calcium chloride 1 kg, sodium carboxymethyl cellulose 200 grams of CMC, 60 grams of methylisothiazolinone, and 100 grams of potassium sorbate.

[0033] Preparation method: first dissolve 400 grams of alum in 5 kg of hot water at 50°C-60°C, spray the alum solution on 40 kg of glutinous rice and 40 kg of potato powder to make it soak and absorb; put the water-containing Put the whole powder of glutinous rice and potato granules into the extruder for puffing treatment, the puffing temperature is controlled at 200°C, and the puffing pressure is 0.6MPa; the puffed glutinous rice and potato granules are sent to the pulverizer for crushing, and sieved with 200 meshes to become puffed starch ; Put puffed starch, xanthan gum, stearic acid amide, calcium chloride, CMC, potassium sorbate and methylisothiazolinon...

Abstract

The invention relates to expanded starch solid powder glue, comprising the following components in parts by weight: 70-90 parts of expanded starch, 5-30 parts of tackifier, 0.05-1 part of complexing agent, 0.01-0.5 part of dispersing agent, 0.1-2 parts of quick dry agent, 0.01-1 part of thickener, 0.01-0.4 parts of bactericide and 0.01-0.4 parts of preservative. The expanded starch powder glue is non-toxic tasteless white powder; solid glue powder and water are stirred and mixed according to the ratio of 1:10 in use, and then the glue powder is dissolved into water and gelatinized to form a thick mucilage; the mucilage has strong cohesive force and good application property, and is anti-mildew and antibacterial, and suitable for bonding of kinds of wallpapers and matrixes; the performance of the mucilage accords with the requirements of the standard of JC / T548-1994 'wallpaper adhesive'. Therefore, the expanded starch solid powder glue has environmental protection and energy conservation effects relatively to liquid glue, and is the development direction of an environment-friendly starch adhesive for the wallpaper.

Description

technical field [0001] The invention belongs to the field of adhesives for wallpaper, and in particular relates to an expanded starch solid powder adhesive and a preparation method. Background technique [0002] At present, most of the environmentally friendly adhesives for wallpaper are liquid starch glue or glutinous rice glue, but liquid starch glue has poor storage stability. Because the water content reaches 80%-90%, liquid starch glue brings a lot of inconvenience to packaging, storage and transportation. At the same time, storage and transportation costs are increased, and more importantly, the liquid starch glue will cause the binder to fail if it freezes during transportation and storage in winter. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a puffed starch solid powder glue with strong cohesive force, more environmental protection and energy saving and its preparation method. [0004] In order to s...
