Description
Technical Field
The application relates to the field of labels, in particular to a self-adhesive label and a production process thereof.
Background
The self-adhesive label is a kind of common label, also called self-adhesive label, instant sticker, pressure-sensitive paper, etc. it is a kind of composite material which uses paper, film or special material as face material, and its back surface is coated with adhesive, and the silicon-coated base paper is used as protective paper, and is made into the finished product label by means of printing and die-cutting, etc..
The application number is 201620031947.3's chinese patent, discloses a waterproof non-setting adhesive label, including polyvinyl chloride film, coated paper, adhesive and scribble silicon protection paper, polyvinyl chloride film side scribbles the lotus leaf emulsion paint, polyvinyl chloride film is transparent setting, be provided with the recess on the polyvinyl chloride film, coated paper is for imbedding in the setting of polyvinyl chloride film, the adhesive is located the recess, scribble silicon protection paper and be located below the adhesive, scribble silicon protection paper and can dismantle with the adhesive and be connected; the waterproof self-adhesive label has excellent waterproof effect.
With respect to the related art among the above, the inventors consider that the following drawbacks exist: the film is made of polyvinyl chloride which is a non-degradable high polymer material, so that the label can not be completely recycled after being separated from sticking materials such as glass and the like, and the environment can be polluted.
Disclosure of Invention
In order to degrade a film on the self-adhesive label and reduce environmental pollution, the application provides the self-adhesive label and a production process thereof.
First aspect, the application provides a non-setting adhesive label, adopts following technical scheme:
a self-adhesive label comprises a release paper layer, an adhesive layer, a surface paper layer and a thin film layer which are arranged in sequence;
the film layer is prepared from the following raw materials in parts by weight: 80-90 parts of polyvinyl alcohol, 10-20 parts of stearic acid, 15-28 parts of modified wood powder fiber, 1-2 parts of dispersant and 1-2 parts of stabilizer.
By adopting the technical scheme, the polyvinyl alcohol has the characteristic of biodegradation, and the final hydrolysate is carbon dioxide and water, so that the polyvinyl alcohol is a good environment-friendly material; because polyvinyl alcohol is rich in hydroxyl, the water resistance is poor, but stearic acid and polyvinyl alcohol are subjected to esterification reaction, so that partial hydroxyl in the polyvinyl alcohol is esterified, and the water resistance of the film layer is improved; meanwhile, the stearic acid can also improve the compatibility of all raw materials, thereby being beneficial to improving the stability of the system.
The wood flour fiber is a vegetable fiber, is low in price, can be subjected to biodegradation automatically, is favorable for environmental protection, can improve the tensile strength of the film layer when being filled in polyvinyl alcohol, and can further enhance the connection strength between the wood flour fiber and the polyvinyl alcohol and further enhance the tensile strength of the film layer when being better compatible with other raw materials.
Optionally, the preparation method of the modified wood flour fiber comprises the following steps: 1) dissolving 10-15 parts of maleic anhydride in 20-30 parts of dimethyl sulfoxide, adding 5-10 parts of hydroquinone, and uniformly stirring and mixing to obtain a modified solution; 2) adding 30-35 parts of wood flour fiber into the modified solution, reacting for 30-50min at 40-50 ℃, and filtering to obtain first wood flour fiber; 3) pouring the first wood powder fiber into 45-55 parts of acetone, standing for 2-3h, and filtering to obtain a second fiber; 4) and drying the second fiber at 60-70 ℃ for 9-11h to obtain the modified wood flour fiber.
By adopting the technical scheme, the esterification reaction is carried out between the maleic anhydride and the wood flour fiber, and the polarity and the hygroscopicity of the wood flour fiber are reduced, so that the compatibility between the wood flour fiber and the polyvinyl alcohol is enhanced, and the adhesiveness between the polyvinyl alcohol and the wood flour fiber is stronger.
Optionally, in step 2), adding the wood flour fiber into 50-60 parts of acetic acid solution with the concentration of 0.05-1mol/L, stirring and reacting for 0.5-1h, filtering, and then adding into the modified solution.
By adopting the technical scheme, acetic acid can react with pectin and other impurities in the wood flour fiber, so that part of pectin and impurities are removed, the adhesion between the wood part of the wood flour fiber and polyvinyl alcohol is improved, and the mechanical property of the film layer is improved.
Optionally, the seaweed polysaccharide also comprises 20-30 parts by weight of seaweed polysaccharide.
By adopting the technical scheme, the algal polysaccharide has good biodegradation property and adhesiveness, so that good film forming property of the mixed raw materials in the film layer can be maintained, and meanwhile, the algal polysaccharide has good hydrophilicity and can accelerate degradation of the film layer.
Optionally, 10-15 parts by weight of wollastonite is also included.
By adopting the technical scheme, the wollastonite is natural mineral fiber, so that the tensile strength and the thermal stability of the film layer can be improved, and simultaneously, the stearic acid can react with the wollastonite to modify the surface of the wollastonite, so that the compatibility between the wollastonite and polyvinyl alcohol is enhanced, and the wollastonite can be better dispersed in the film layer system.
Optionally, the composition also comprises 5-10 parts by weight of acetic anhydride.
By adopting the technical scheme, acetic anhydride is easy to hydrolyze to generate acetic acid, and an acidic condition is formed, so that the degradation speed of the thin film layer is accelerated.
Optionally, the dispersant is polyethylene glycol.
By adopting the technical scheme, the polyethylene glycol can improve the compatibility between various raw materials such as polyvinyl alcohol, modified wood flour fiber and the like.
Optionally, the stabilizer is a rare earth stabilizer.
Through adopting above-mentioned technical scheme, the rare earth stabilizer can make the structure of thin layer more compact to improve the mechanical strength of thin layer, also can purify impurity simultaneously, make the thin layer more clear transparent.
