Abstract
The present invention provides a multifunctional label adhesive and its preparation method. It is made up by using polyvinyl alcohol, starch, hydrochloric acid, sulfuric acid, formaldehyde, sodium hydroxide and dryer according to a certain mixing ratio and a certain temp. through the process of sequential stirring. Said adhesive made up by using the present invention possesses quick drying speed and strong initial cohesive force, is suitable for use in high-speed labeller. Besides, said product also can be mixed with water to obtain different concentration for manually-pasting various labels and binding various paper boxes, paper products and building material, etc..
Description
The invention belongs to technical field of adhesive, be mainly used in the bonding of paper product and other nonmetallic substance, be specially adapted to the tackiness agent that trade mark is pasted in mechanize at a high speed.
The trade mark of beer and similar bottled product generally all adopts the mechanize decals, raising along with production-scale continuous expansion and production rate, general trade mark adhesive, as starch paste and yellow starch gum etc., exist rate of drying slow, initial cohesiveness is low, and phenomenons such as the rate of announcing successful tender height and label displacement breakage do not meet national regulation.Chinese patent application numbers 89107363.9, exercise question is that a kind of mechanize label sticks with glue agent, though this invention technology is simple, tack is good, but still exists rate of drying slow, can not satisfy high-speed labeling technology requirement.
It is fast to the purpose of this invention is to provide a kind of rate of drying, and initial bonding strength is strong, and trade mark is not mouldy, a kind of multifunctional trademark adhesive and method for making thereof that cementability is good.
The object of the present invention is achieved like this, in having the reactor of heating unit, add gauge water, and then add 95-100 ℃ of polyvinyl alcohol intensification, treat the polyvinyl alcohol dissolving, add hydrochloric acid, sulfuric acid then, adding quantitative formaldehyde again reacted under 85 ± 5 ℃ 2-3 hour, again dissolution of sodium hydroxide is added in the reactor and neutralize, lower the temperature 60 ℃ then, starch is added water furnishing pasty state to add in the reactor, siccative is added in the reactor with the hot water dissolving, the 70 ℃ of stirring reactions that heat up were finished product in 30 minutes again.
With the tackiness agent that the present invention makes, rate of drying is fast, can cement about 20 seconds, not only can satisfy mechanize high speed decals, and thin up as required, to adapt to all kinds of labels of artificial stickup, also can bonding all kinds of packing boxes, paper thorn product, material of construction etc.
Each forms to divide:
Polyvinyl alcohol: 90-180 starch: 50-120
Formaldehyde: 30-50 sulfuric acid: 5-10
Hydrochloric acid: 15-22 sodium hydroxide: 8-10
Water: 800-1000 siccative: 5-12
Most preferred embodiment of the present invention is as follows:
Polyvinyl alcohol: 150 sulfuric acid: 5
Starch: 0 sodium hydroxide: 9
Formaldehyde: 45 siccative: 5
Hydrochloric acid: 20 water: 1000
A. in having the reactor of heating unit, add entry, add 95-100 ℃ of polyvinyl alcohol intensification again, polyethylene is dissolved fully;
B. hydrochloric acid, sulfuric acid are mixed in the back adding reactor and stir;
C. formaldehyde is added in the reactor, be cooled to 85 ℃+5 stirring reaction 2-3 hours;
D. with sodium hydroxide with 5 times of cold-water solutions, add in the reactor, be cooled to 60 ℃;
E. with starch with 2 times of water furnishing pasty states, add the 70 ℃ of reactions 30 minutes that heat up in the reactor;
F. siccative is used the hot water dissolving, add in the reactor, stirred 30 minutes, be cooled to 30-40 ℃, put into pail pack and be finished product.
Claims (2)
1, a kind of multifunctional trademark adhesive, its major ingredient by: polyvinyl alcohol, starch, siccative, hydrochloric acid, sulfuric acid, formaldehyde, sodium hydroxide and water are mixed with, and it is characterized in that the content (weight ratio) of each composition in the tackiness agent is respectively:
Polyvinyl alcohol: 90-180 starch: 50-120 sulfuric acid: 5-10
Hydrochloric acid: 15-22 formaldehyde: 30-50 sodium hydroxide: 8-10
