3.5-3.9, deionized water 56-60.
Further, the composite modified polyvinyl alcohol preparation method of the starch the following steps are included:
(1) starch uniformly pretreatment of starch: is added to the polyoxometallate that mass fraction is 6.5% by 1:10 mass ratio
In aqueous solution, be heated to 76 DEG C, with 1200r/min revolving speed stir 40min, then filtered, drying to constant weight to get；
(2) the composite modified polyvinyl alcohol of starch: polyvinyl alcohol is dissolved in deionized water, be configured to mass fraction be 15% it is poly-
In vinyl alcohol aqueous solution, 55 DEG C are then heated to, polyvinyl alcohol water solution is stirred continuously with 1800r/min revolving speed, is stirred
It is above-mentioned resulting by pretreated starch into the polyvinyl alcohol water solution being stirred continuously after mixing 10min, it is small to continue stirring 1
When, obtain polyvinylalcohols starch mixed liquor, 70 DEG C adjusted the temperature to polyvinylalcohols starch mixed liquor, keeps the temperature 5min, then to
The 3- chlorine-2-hydroxyl propanesulfonate of its quality 0.62% is added in polyvinylalcohols starch mixed liquor, with the stirring of 1200r/min revolving speed
35min obtains mixed system, and mixed system is added in reaction kettle, under inert gas atmosphere, adds into mixed system
The ammonium persulfate of its quality 0.1% and 0.12% diethyl amino propylamine, at 88 DEG C, with 800r/min revolving speed stirring 2 hours, so
After carry out cooling discharging, it is dry to get the composite modified polyvinyl alcohol of starch by rotary evaporation.
Further, step (1) starch is that soybean starch and Faba bean starch are mixed by 10:1 mass ratio.
Further, step (1) the polyoxometallic acid saline solution is 12- tungstophosphoric acid aqueous solutions of potassium.
Further, step (2) inert gas is neon.
Further, step (2) pretreated starch and the polyvinyl alcohol mass ratio of passing through is 1:3.
Further, the activation nano zeolite powder, preparation method thereof are as follows: be with chloroform by 2- chloroethyl sulfonic acid chloride
Medium carries out dispersion impregnation to nano zeolite powder, specifically: 2- chloroethyl sulfonic acid chloride is dissolved in by 1.2:55 mass ratio
In chloroform, the nano zeolite powder of chloroform quality 10% is then added again, at a temperature of 0.02MPa vacuum degree, 112 DEG C,

Embodiment and comparative example adhesive property are detected:
(1) the equal paper slip of several areas, thickness the first glutinous time test of adhesive: is pasted on to the table of vial with adhesive
A paper slip is torn every 5s in face, until paper slip is stuck when tearing downwards, paper slip can be destroyed when time be just glutinous when
Between；
(2) it the storage period test of adhesive: is tested by GB/T 7751-1987 standard；
(3) the resistance to room temperature of adhesive is aqueous: by adhesive with 30g/m2Coating weight is uniformly coated on label, later pastes label
On vial clean in advance and flatten, by the vial of label room temperature, relative humidity 68% environment in place 3
It after it, is vertically immersed in 25 DEG C of water, for several times every 12h rotary glass bottle, sees label whether there is or not alice or fall off, it is parallel with 3
At least 1 alice or the time before falling off indicate water resisting time in sample；
Table 1
As can be seen from Table 1, the glutinous time at the beginning of the present invention prepares glued board adhesive is short, and storage period is long, water-tolerant.
Drying time: sample adhesive is coated on label paper, is affixed on vial, is weighed on assay balance at once,
Weight includes bottle, trade mark, the moisture in adhesive and solid four quality sums (W1).Drying at room temperature after having claimed, often
It is primary every 2h weighing, the corresponding quality of 2h, 4h, 6h, 8h (W2, W3, W4, W5 etc.) can be obtained.Later, by sample in drying
It is placed 2 days in device, is completely dried sample and is re-weighed once.This inferior quality is considered bottle, trade mark and three matter with solid
The sum of amount (WH).Aqueous quality is set as W in adhesive, then W=W1-WH, and the biodiversity lost within 2h is W1-W2.
Thus calculate the ratio that moisture content is lost in 2h: fluid loss=(W1-W2)/W uses same method, available 4h, 6h,
The dehydration ratio of 8h.Using the time as horizontal axis, dehydration ratio is the longitudinal axis, obtains the drying curve of adhesive.It is looked on drying curve
Time used when dehydration 80% out, the drying time as the sample；
Table 2
As can be seen from Table 2, glued board prepared by the present invention is short with modified polyvinylalcohol adhesive drying time, rate of drying
Fastly.
