Test example 1
Adhesive label with above-described embodiment obtains is cut into 1 * 1cm
2, weight is the specification of 20-30mg, adopts soil to bury method, and adhesive label is embedded in the damp soil under room temperature, every interval 10d sampling is once got three samples at every turn, observes plane materiel superficial degradation situation.And with distilled water washing three times, vacuum drying, its average weight-loss ratio of weighing measurement.By test figure in the table 1 as can be known, label is obvious in degraded in soil, can see obvious cavity at 40 days, can't take out after 100 days and finish sample, as shown in table 1, the degradation speed of the label that wherein obtains among the embodiment 5 is obviously greater than the label of other embodiment.
The table 1 different measuring time, the measurement result of label weight-loss ratio
Test example 2 is measured the degraded situation of the plane materiel of different formulations take facestock layer as example, and wherein the PHA in the plane materiel selects P (3HB-co-4HB) (molar content of 4HB is 10%).
The prescription of plane materiel is as shown in table 2, and wherein the addition of each plastifier, nucleator and lubricant is with embodiment 5, and the addition of each component of numeral front in the bracket is measured each plane materiel at the weight-loss ratio of different time, and measuring method is with test example 1.
Table 2 is measured under the different formulations degraded situation of plane materiel take P (3HB-co-4HB) as example
By the data in the table 2 as can be known, in plane materiel, only contain P (3HB-co-4HB), do not contain PLA, or when containing a small amount of starch, degradation speed is the fastest, is respectively 78.7% and 79.1%, along with the addition of PLA or starch increases, degradation speed descends gradually, but because P (3HB-co-4HB) cost is higher, therefore also needs to add PLA and starch as filling agent.The present invention has drawn rational ratio between PHA, PLA and the starch through lot of experiments, is added with in addition plastifier, nucleator and lubricant, makes label of the present invention have faster degradation speed and preferably mechanical property, has also reduced simultaneously production cost.
Viscosity, water tolerance and the bonding strength of oxidized starch gluing agent can also be adjusted and improve to the selection of each component and weight proportion thereof in the adhesive of the present invention when guaranteeing biodegradability, effectively.Base stock of the present invention adopts the Ge Laxin paper of coating silicone oil, has completely biodegradability, can effectively protect the adhesive at the plane materiel back side, supports plane materiel, makes it make things convenient for cross cutting, waste discharge.
The invention solves the problem of film class adhesive label contaminated environment, Biodegradable material polyhydroxyalkanoate (PHA) is applied to the adhesive label industry, just can realize complete biodegradable so that plane materiel and adhesive need not compost treatment.Its mechanism of degradation is: starch is as the microbial nutrition source, and the hydroxyl of starch provides physical attachment point, and the adsorption effect of starch helps to produce local dense micropopulation.Microbiological release diastase (amylase), starch issues unboiled water solution (metabolism) in the effect of enzyme, produces a large amount of micropores, is conducive to entering and surviving, breed of bacterium, be convenient to bacteriogenic PHA digestive enzyme and be diffused in the label material matrix, make its degraded.
Label construction of the present invention is simple, preparation technology is easy, cost is low, is applicable to sticking glass, plastics etc.
Above-described embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.

(3) preparation of base stock: with being coated with silicon equipment at base stock surface-coated silicone oil, the amount of being coated with of silicone oil is 1～1.5g/m
2, the base stock that then will be coated with silicone oil is 120 ℃～160 ℃ drying in oven, and get final product;
(4) adhesive that step (2) is obtained is applied on the plane materiel that step (1) obtains, and glue-spread is 21～27g/m
2, the oven for drying through 100 ℃～130 ℃ obtains glue-coated plane materiel; The base stock that glue-coated plane materiel and step (3) are obtained is by the pressing of rubber rollers and cylinder, and get final product.
