Description
Technical field
The invention belongs to starch conversion and its applied technical field in wallpaper glue, more particularly to a kind of environment-friendly type starch base
Wallpaper glue converted starch and preparation method thereof.
Background technology
Wallpaper glue is mainly used to sticking wallpaper and wall cloth, is a kind of building materials decoration industry commonly adhesive, clings wallpaper
With ensure that the service life of wallpaper is most basic function.Common wallpaper glue is mostly wanted based on starch glue powder cooperation polymerization glue
Raw material, wherein starch glue powder are easy to cause the harmful effects such as discoloration to wallpaper since PH high, salt content are high；It polymerize in glue
The nuisances such as formaldehyde, benzene content is high, and harm is generated to health, especially healthy and safe in consumer's pay attention to day by day and pursuit
Severe test instead starch base wallpaper glue are faced with the market in the epoch of environmental-protecting performance, chemical industry adhesive.Starch
Derive from a wealth of sources, huge number, be renewable resource, environment protection health, be in building decorating industry gluing product it is rare can biology drop
It solves, without formaldehyde, totally nontoxic, harmless, environmentally protective healthy product, wallpaper cohesive force can be effectively improved and prevent wallpaper
The defects of jaundice, cracking, alice.
At present production wallpaper glue starch mostly using converted starch, ative starch as primary raw material, due to using converted starch with
Ative starch mixing formula, reasons, this hair such as cause in wallpaper glue the anti-aging property of starch, freeze-thaw resistance, cohesive force unbalanced
It is bright that suitable starch conversion is carried out to starch, while using the production technology of food grade converted starch, it is ensured that wallpaper glue ring health care
Health.
Invention content
The present invention provides a kind of environment-friendly type starch base wallpaper glue converted starch, has health environment-friendly, at low cost, preparation side
The advantages that method is simple, and reaction condition is mild.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of environment-friendly type starch base wallpaper glue converted starch is made by the raw material of following parts by weight meter：Ative starch
100 parts, 2.7~7.8 parts of alkali, 0.5~1.4 part of sodium citrate, 0.2~1.0 part of sodium ethylene diamine tetracetate, sodium trimetaphosphate
0.3~1.2 part, 3.0~7.5 parts of acetic anhydride, 300 parts of water.One side of sodium citrate and disodium ethylene diamine tetraacetate in formula
Face can effective heavy-metal ion removal, on the other hand make made of wallpaper glue color and luster it is white, it is not easy to become desaturation water.
It is applied in combination, starch is injured smaller using both sodium carbonate and sodium hydroxide in inventive formulation.Using lye
Combined coefficient is high, and the modified starch products impurity of production is less, and effect is more preferable；Especially be added to removal of heavy metal ions agent and
It is finally cleaned with softened water, considerably reduces the content of beary metal in starch, improved wallpaper glue and be easy discoloration, corruption
Difficult point.
Preferably, the ative starch is potato starch, tapioca, cornstarch, wheaten starch or rice starch
One or more of mixtures.
Preferably, the alkali is selected from the group of one or more of sodium bicarbonate, sodium carbonate or sodium hydroxide
It closes.Preferably, the alkali is the combination of sodium carbonate and sodium hydroxide, wherein 1.5~7.5 parts of sodium hydroxide, sodium carbonate
0.3~1.2 part.
A kind of preparation method of the environment-friendly type starch base wallpaper glue converted starch, this method comprises the following steps：
1) alkali is completely dissolved in suitable quantity of water, is stirred, it is ensured that precipitated, obtained lye, and cooled down without solid
It is spare to 15-20 DEG C,
Dissolving stirring 25-30min in the water of formula surplus is added in ative starch, sodium citrate and sodium ethylene diamine tetracetate
Starch milk is obtained, is cooled to 15-20 DEG C；
2) lye configured is slowly added in starch milk, is adjusted in pH to the 12.0-12.2 ranges of starch milk, then
Sodium trimetaphosphate is added, while continuing to maintain starch milk pH to stablize within the scope of 12.0-12.2 with lye；
3) after the mixed liquor that step 2) obtains reacts 5-7h at a temperature of 28-35 DEG C, pH to 8.1-8.3 ranges are adjusted with acid
It is interior；
4) in the mixed liquor obtained to step 3), lye is added dropwise on one side, acetic anhydride is added dropwise on one side, control the dropwise addition speed of the two
Degree makes starch milk pH maintain progress acetylization reaction within the scope of 8.2-8.3；After being added dropwise, the reaction was continued 40-50 minutes,
It is 6.0-6.5 to be adjusted with acid pH, obtains converted starch slurries；
5) converted starch slurries are washed, are dehydrated, are dry, obtain product.
Preferably, carrying out pneumatic conveying drying using 100-130 DEG C of hot wind when dry.
Compared with prior art, the present invention having the following advantages that：
1) it is adopted for raw material using food starch such as potato, cassava, corn, wheat, waxy corn and glutinous rice and rice starch
Different Adhesive wall paper glue converted starches are prepared with the technique being esterified afterwards is first crosslinked, it is resistance to solve common wallpaper glue modified starch
The problems such as shear at high temperature is poor, and winter wallpaper glue is easy ageing hardening, while entire technical process is given birth to using food-grade modified starch
Production. art further promotes the environmentally friendly compatibility of wallpaper glue.
2) use sodium carbonate as react catalyst, can higher temperatures without alcohol, simple water phase, without adding inorganic salts
Under conditions of synthesize wallpaper glue converted starch, sodium carbonate can prevent the gelatinization of starch, and can participate in catalytic starch esterification
Reaction increases the concentration of starch reaction system, improves the reaction efficiency of reagent, and the reaction yield for improving starch is increased by 88~90%
92~95% are added to, while eliminating the Organic Alcohol problem high to the pollution of environment and recovery cost；
3) starch that preparation method of the present invention obtains has good frost resistance and caking property, is recycled freeze thawing 3 times or more
(being freezed 24 hours in subzero 30 DEG C of refrigerators, it is a cycle to take out in thaw at RT 24 hours), product not bleed, viscosity is not
Decline, with before freeze thawing, solve wallpaper glue winter intolerant to jelly, it is inconvenient to use the problems such as；In addition, starch of the present invention can
Substitute and commonly use the chemical industry substance such as polyvinyl alcohol, white glue with vinyl etc. that adds in wallpaper glue, the glue made with all with chemical industry substance
Unanimously, pollution and health hazard are reduced, while reducing cost.
Specific implementation mode
Below by specific embodiment, technical scheme of the present invention will be further explained in detail.It should be appreciated that this hair
Bright implementation is not limited to the following examples, and the accommodation in any form made to the present invention and/or changed will all be fallen
Enter the scope of the present invention.
In the present invention, if not refering in particular to, all parts, percentage are unit of weight, used equipment and raw material etc.
It is commercially available or commonly used in the art.Method in following embodiments is unless otherwise instructed the normal of this field
