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
The invention belongs to wallpaper and use the binding agent field, be specifically related to a kind of expanded starch pressed powder glue and preparation method.
Background technology
Wallpaper is mostly liquid starch glue or Xiao rice glue with the environmental protection binding agent at present, but liquid starch glue exists poor storage stability, because water content reaches 80%-90%, liquid starch glue to packing, storage and travelling belt much inconvenience, storage and trucking costs have been increased simultaneously, main is liquid starch glue transports in the winter time with storage process in as freeze after, can cause adhesive failure.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of cohesive force by force, environmental protection and energy-conservation expanded starch pressed powder glue and preparation method more.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
Expanded starch pressed powder glue of the present invention is comprised of following component, the weight part of each component is: expanded starch 70-90 part, tackifier 5-30 part, dispersion agent 0.01-0.5 part, complexing agent 0.05-1 part, quick dry agent 0.1-2 part, thickening material 0.01-1 part, sterilant 0.01-0.4 part, sanitas 0.1-0.6 part.
Expanded starch in expanded starch pressed powder glue of the present invention can be one or both and the above starch material that is combined as in glutinous rice, potato and corn.Pulverize and form after adopting bulking process to process, preferably glutinous rice is raw material.Common starch is due to water insoluble under normal temperature, can't be as the raw material of pressed powder glue, but after starch is processed by high-temperature high-pressure swelling, starch particle disintegrates, form foamy structure, degraded and dextrinization simultaneously, becoming can gelatinization in cold water, has the advantages that tack is good, viscosity is high, cohesive strength is large.
Tackifier in expanded starch pressed powder glue of the present invention can be one or both and the above combinations in xanthan gum, dextrin and pre-gelatinized starch.Xanthan gum is to be fermented through Xanthomonas campestris by carbohydrate, the many pools of the outer microorganism of the born of the same parents of generation.Due to its macromole special construction and colloid property, there is the effect of tackify, thickening in binding agent.Dextrin be starchy material through thermal treatment or pre-treatment, starch degradation is formed soluble in water, be dissolved in water the characteristics with very strong viscosity.Pre-gelatinized starch is the product that starch obtains through gelatinization, drying, has the advantages that cold water becomes to stick with paste.
Dispersion agent of the present invention can stearic acid, one or both and above combination of stearic amide or erucicamide.Dispersion agent coats by the surface to expanded starch, tackifier, thickening material, makes it easy to disperse in water, prevents caking phenomenon in its dissolution process.
Complexing agent in expanded starch pressed powder glue of the present invention can be one or both the combination in borax, alum.Complexing agent can with starch molecule in the hydroxyl complexing form reticulated structure, the effect that there is thickening and improve tack.But excessive complexing agent makes the binding agent gel on the contrary, lose viscosity simultaneously.
Quick dry agent in expanded starch pressed powder glue of the present invention can be one or both the combination in calcium chloride, wilkinite.Quick dry agent can improve the rate of drying of the rear binding agent of wallpaper construction, and wilkinite not only can improve the rate of drying of binding agent, is also the shearing thixotropic agent of fluid simultaneously, increases the application property of binding agent.
Thickening material in expanded starch pressed powder glue of the present invention is one or both the combination in Xylo-Mucine, polyacrylamide.The viscosity that act as the adjusting binding agent of thickening material, make it have low-solid content, full-bodied performance.
Sterilant in expanded starch pressed powder glue of the present invention is one or both the combination in 2,4,5,6-tetrachloro-1,3 benzene dicarbonitrile, methylisothiazolinone.This two kinds of fungicidal preservatives that sterilant is broad-spectrum, effectively algae, bacterium and fungi.Have effective level few, nontoxic pollution-free, very easily be blended in all kinds of formulas, and the PH use range is wide, the advantage of heavy metal free ion.
Sanitas in expanded starch pressed powder glue of the present invention is one or both the combination in Sodium Benzoate, potassium sorbate.Two kinds of sanitass are and can be applicable to food.
The preparation method of expanded starch pressed powder glue of the present invention for by starch material infiltration, puffing, pulverize, sieve, the operations such as auxiliary agent mixing, drying and packing are prepared from, the preparation method of expanded starch pressed powder glue is as follows:
(1) first by the complexing agent of proportioning, be dissolved in a certain amount of water, the 5%-15% that the water yield is starch material weight, the starch material weight part is 70-90 part, and this enveloping agent solution is sprayed in starch material and it is infiltrated absorb;
(2) moisture starch material is put into to bulking machine and carry out puffing, swelling temperature is controlled at 180 ℃-230 ℃, and bulking pressure is 0.5-0.8MPa;
(3) starch material after expanded is sent into to pulverizer and pulverized, after sieving, become expanded starch;
(4) expanded starch, tackifier, dispersion agent, quick dry agent, thickening material, sterilant, sanitas are carried out to the high speed dispersion mixing by proportioning, then carry out drying and packing.
Expanded starch plastic powder of the present invention is a kind of nonpoisonous and tasteless white powder, in use, after solid rubber powder and water are uniformly mixed with the ratio of 1:10 left and right, water-soluble and the gelatinization of rubber powder, form the rubber cement of thickness, rubber cement has that cohesive force is strong, the good antimildew and antibacterial of application property, be applicable to the bonding of various wallpapers and matrix, and performance meets JC/T548-1994 " wallpaper glue stick " standard-required.Therefore with respect to liquid glue, expanded starch solid state powder glue has more environmental protection and energy-conservation, is also the developing direction of wallpaper with environmental protection starch based binding agent.
