Wherein the test result of comparative example 4 was measured using the acrylate adhesive sticker prepared in comparative example 4.
And (3) analyzing test results:
(1) as can be seen by combining examples 1 to 12 and comparative examples 1 to 4 with Table 4, the use of styrene and hydroxyethyl methacrylate improves the water resistance of the adhesive sticker. The reason for this is probably that after the styrene participates in the polymerization, the flexibility of the molecular structure of the acrylic emulsion can be reduced, the free volume of the adhesive sticker coating film is reduced, the hardness of the adhesive sticker coating film is ensured, and the water molecules are prevented from permeating into the pressure-sensitive coating film; and the hydroxyethyl methacrylate contains more hydroxyl groups, so that more hydroxyl groups are distributed on the surface of the polymerized acrylic emulsion, acrylic emulsion particles can be mutually crosslinked into a network structure, the probability of water molecules permeating into the adhesive sticker coating film is reduced, the probability of foaming, wrinkling and falling of the adhesive sticker coating film is reduced, and the water resistance of the adhesive sticker is improved.
(2) As can be seen by combining examples 1-3 and example 4 with Table 4, the water resistance of the sticker can be improved by using the stabilizer composed of carboxymethyl cellulose and silica particles. The reason for this is probably that the stabilizer has excellent wetting action and dispersion action, which promotes the particle size of acrylic emulsion molecules to be reduced, and the gaps between particles after the acrylic emulsion is coated with films are reduced, so that water molecules are not easy to enter the inside of the films, thereby improving the water resistance of the adhesive sticker.
(3) As can be seen by combining examples 1 to 4 and example 5 with Table 4, the water resistance of the adhesive sticker can be improved by using the terpene resin. The reason may be that the terpene resin contains polar groups and can be crosslinked with acrylic emulsion to form an interpenetrating network structure, so that the water resistance of the adhesive sticker is further improved.
(4) As can be seen by combining examples 5 and 10-11 with Table 4, the water resistance of the adhesive sticker can be improved by using tert-butyl hydroperoxide as an oxidizing agent and sodium metabisulfite as a reducing agent. The reason for this is probably that, compared with the case of using ammonium persulfate as an oxidizing agent in example 10, the case of using FF6 as a reducing agent in example 11, tert-butyl hydroperoxide as an oxidizing and reducing agent with sodium metabisulfite, the conversion of the acrylic emulsion was improved, the monomer residue was reduced, and the addition of the acrylic emulsion was advantageous for forming a denser coating film, thereby improving the water resistance.
Test 2: the stickers of examples 13-32 and comparative examples 1-4 tested samples for tack in a humid environment: referring to the test standard in GB/T4851-2014, the adhesive sticker sheets in examples 13-32 and comparative examples 1-3 were taken, and one side of each sheet was uniformly coated with an adhesive sticker having a thickness of 0.5mm to prepare a test sample.
The test method comprises the following steps: referring to method A in GB/T4851-2014: in the method for testing the permanent adhesion of the adhesive tape and the vertical standard steel plate, the weight of a test weight is 500g, the time for the adhesive failure of the paper sheet of the adhesive sticker is measured in the environment with the temperature of 23 ℃ and the humidity of 90% RH, and the longer the time, the better the permanent adhesion of the test sample is, and the test result is shown in table 5.
TABLE 5 test results of self-adhesive tack holding properties of examples 13 to 32 and comparative examples 1 to 4
And (3) analysis of test results:
(1) as can be seen from the combination of examples 13 to 32 and comparative examples 1 to 4 and Table 5, the tack adhesives prepared from styrene and hydroxyethyl methacrylate can improve the tack strength of the tack adhesives. The reason for this is probably that the rigidity and the crosslinking density of the adhesive sticker after film forming are improved by adopting styrene and hydroxyethyl methacrylate, so that water molecules are difficult to permeate into the inside of the adhesive sticker coating film to swell under a humid environment of the double-sided adhesive layer, the adhesive sticker layer is difficult to fall off, and the adhesive holding capacity of the adhesive sticker is improved.
(2) It can be seen from the combination of example 13 and example 16 and table 5 that the adhesive sticker prepared from carboxymethyl cellulose and silica particles can improve the adhesion of the adhesive sticker, and the reason may be that carboxymethyl cellulose has a wetting effect on silica particles, so that the surface energy of the silica particles is improved, the silica particles are promoted to be spontaneously adsorbed on the two-phase interface of the adhesive sticker emulsion particles to form a solid protective film, thereby effectively preventing aggregation or agglomeration between the emulsion particles from causing the particle size of the emulsion particles to increase, maintaining the compactness of the adhesive sticker layer, and making water molecules difficult to permeate into the adhesive sticker coating film, thereby improving the adhesion of the adhesive sticker in a humid environment.
(3) As can be seen from the combination of example 16 and comparative example 17 and Table 5, the tack adhesive obtained by using the terpene resin can improve the tack strength of the tack adhesive. The reason for this is probably that the terpene resin can cross-link with the acrylic emulsion to form an interpenetrating network structure, so that the compactness of the self-adhesive coating is further improved, and water molecules are difficult to permeate into the self-adhesive coating, thereby improving the adhesion of the paper sheet of the self-adhesive book in a humid environment.
(4) As can be seen from the combination of example 17 and comparative examples 22 to 23 and Table 5, the tack adhesive obtained by using t-butyl hydroperoxide as an oxidizing agent and sodium metabisulfite as a reducing agent can improve the tack strength of the tack adhesive. The reason for this is probably that the tert-butyl hydroperoxide has better oxidizing property and reducing property with sodium pyrosulfite, the conversion rate of acrylic emulsion can be improved, the monomer residue is reduced, the increase of acrylic emulsion is beneficial to forming more compact coating film, so that water molecules are difficult to permeate into the inside of the non-setting adhesive coating film, and the holding viscosity of the paper sheet of the non-setting adhesive book in a humid environment is improved.
(5) As can be seen by combining examples 17 and 24 and Table 5, the tack adhesive prepared by using sodium 2-acrylamido-2-methylpropanesulfonate, sodium allyl ether sulfonate and sodium olefin oxysulfonate can improve the tack strength of the tack adhesive. The reason for this is probably that the emulsifier such as sodium dodecyl diphenyl ether disulfonate is easy to migrate to the surface of the adhesive coating during the use of the adhesive sticker, so that the adhesiveness and water resistance of the adhesive sticker are reduced, and the holding viscosity is also reduced. The amido-2-methyl sodium propane sulfonate, the sodium allyl ether sulfonate and the sodium olefin oxysulfonate are reactive emulsifiers and can be used as monomers to participate in emulsion polymerization, and the emulsifiers are combined with the emulsion more firmly and are not easy to migrate. Can keep the adhesion and water resistance of the adhesive sticker coating, thereby improving the adhesion of the paper sheet of the adhesive sticker book in a humid environment.
(6) As can be seen from the combination of example 17 and examples 25 to 27 and Table 5, the tack strength of the sticker can be improved by applying the surface treatment liquid to the surface of the sheet layer before the sticker is applied. The reason for this is probably that after the surface treatment liquid is used for treatment, the acrylic emulsion in the self-adhesive and the N-hydroxymethyl acrylamide are subjected to a cross-linking reaction, so that the self-adhesive is more firmly and compactly connected with the paper sheet layer, and water molecules are difficult to permeate into the self-adhesive from the position between the paper sheet and the self-adhesive, thereby improving the holding viscosity of the paper sheet of the self-adhesive book in a humid environment.
Test 3: test samples for peel strength test of the adhesive stickers of examples 13 to 32 and comparative examples 1 to 4: test samples were prepared according to the specifications in GB/T2792-2014 for examples 13-32 and comparative examples 1-4.
The test method comprises the following steps: referring to method 3 in GB/T2792-2014: the 180-degree peel strength test method of the double-sided adhesive tape and the transfer adhesive tape and the stainless steel plate tests the peel strength of the double-sided adhesive tape and the stainless steel plate and records the peel strength A, the larger the measured peel strength A is, the better the adhesive property of the self-adhesive sticker is, and the test results are shown in Table 6;
TABLE 6 Peel Strength test results of Stickers and stainless Steel plates
And (3) analyzing test results:
(1) as can be seen from the combination of examples 13 to 32 and comparative examples 1 to 4 and Table 6, the adhesive stickers produced using hydroxyethyl methacrylate can improve the peel strength between the adhesive stickers and the adherend. The reason may be that the crosslinking density of the adhesive emulsion is increased by adopting hydroxyethyl acrylate, so that the viscosity of the adhesive is increased, and the bonding strength of the adhesive and an adhered object is improved.
(2) As can be seen from the combination of examples 13 to 15 and example 17 and Table 6, the adhesive stickers produced using terpene resins can improve the peel strength between the adhesive stickers and the adherend. The reason may be that the terpene resin is adopted to increase the crosslinking density of the adhesive sticker emulsion and enhance the viscosity of the adhesive sticker; meanwhile, the terpene resin has a tackifying effect, so that the viscosity of the adhesive sticker is further enhanced; thereby improving the bonding strength of the self-adhesive and the bonded object.
(3) As can be seen from the combination of examples 13 to 20 and comparative examples 1 to 4 and Table 6, the application of the surface treatment liquid to the sheet surface before the application of the adhesive sticker can improve the peel strength between the adhesive sticker and the adherend. The reason may be that the silane coupling agent in the surface treatment liquid can be coupled with the acrylic emulsion and also can be coupled with the surface of the paper sheet, and an interface layer is formed between the self-adhesive and the paper sheet layer, so that the bonding strength between the surface of the paper sheet and the acrylic emulsion and the paper sheet is enhanced; meanwhile, the structure of the N-hydroxymethyl acrylamide has more polar groups which can be crosslinked with the polar groups in the self-adhesive sticker; the silane coupling agent and the N-hydroxymethyl acrylamide are matched together, so that the bonding strength of the self-adhesive paper sheet and the self-adhesive is improved, and the peeling strength of the self-adhesive paper sheet is finally improved.
