The rest is the same as in example 11.

Example 16

The corrosion-resistant album of the present example is different from example 14 in that: the raw materials also comprise 1g of dispersant, and the dispersant is composed of maleic anhydride-ethanolamine-acrylic acid, polyphosphate ester and alkyl sulfonate according to the mass ratio of 2.5:2: 1.5. The rest is the same as in example 14.

Wherein the alkyl sulfonate is sodium octadecyl sulfonate, the alkyl carboxylate is sodium dodecyl glyceryl ether carboxylate, and the polyphosphate is diphenyl phosphate.

The amounts (g) of the dispersants added to the starting materials in examples 17 to 18 are shown in Table 7, and the rest is the same as in example 16.

The process for producing the corrosion-resistant photo album of examples 16-18 differs from example 14 in that: in the step 3), the adhesive and water are stirred for 15min at a stirring speed of 1000rpm according to a mass ratio of 4:1.2, and then the filler, the coupling agent, the defoaming agent, the anti-cracking agent, the bactericide and the dispersing agent are added and stirred for 10min at a stirring speed of 800 rpm. The rest is the same as in example 14.

Comparative example 1

The anti-corrosion photo album of the comparison example comprises a photo album cover and photo album inner pages, wherein the photo album cover and the photo album inner pages are made of hard paperboards.

Comparative example 2

The anti-corrosion photo album of the comparison example comprises a photo album cover and photo album inner pages, wherein the photo album cover and the photo album inner pages are made of hard paperboards, the surfaces of the photo album cover and the photo album inner pages are coated with anti-corrosion layers, and the anti-corrosion layers are made of the following raw materials by weight: 30g of binder, 15g of filler, 3g of coupling agent and 0.5g of defoaming agent.

Wherein the binder is chitosan. The filler is silica. The coupling agent is 3-isocyanic acid propyl triethoxy silane. The defoaming agent is composed of dimethyl silicone oil and polyether according to a mass ratio of 4: 2.5.

The production process of the anti-corrosion photo album comprises the following steps:

1) carrying out sand blasting treatment on the surfaces of the photo album front cover and the inner page to ensure that the surface roughness Ra of the photo album is 7.6;

2) performing electron beam irradiation treatment on the photo album cover and the inner page subjected to sand blasting treatment in the step 1), wherein the electron beam irradiation dose is 30KGy, and the irradiation time is 5 min;

3) stirring the binder and water for 15min at a stirring speed of 1000rpm according to a mass ratio of 4:1.2, and then adding the filler, the coupling agent and the defoaming agent and stirring for 10min at a stirring speed of 800 rpm;

4) coating the anticorrosion material obtained in the step 2) on the photo album cover, wherein the thickness of the anticorrosion coating is 2mm, and drying the photo album cover at the temperature of 80 ℃ for 4h to obtain the anticorrosion coating.

Performance test

Detection method/test method

The corrosion-resistant photo albums of examples 1 to 18 and comparative examples 1 to 2 were tested according to the test standard of GB-T1771-2007 neutral salt spray resistance, and the test results are shown in Table 8.

TABLE 8 comparison of Corrosion protection photo album neutral salt fog test data for examples 1-18 and comparative examples 1-2

Comparing example 1, example 2 and example 3 with comparative example 1 and comparative example 2 and combining table 8, it can be seen that the anticorrosion layer can greatly improve the anticorrosion performance of the photo album and prolong the service life of the photo album.

Comparing examples 1 to 3, example 4, example 5 and example 6 with comparative examples 1 and comparative example 2 and combining table 8, it can be seen that the addition amount of zinc silicate, titanium dioxide, barium phosphate, zirconium oxide and silicon dioxide in the filler has an effect on the corrosion prevention effect of the corrosion prevention layer, and the corrosion prevention effect is better when the mass ratio of zinc silicate, titanium dioxide, barium phosphate, zirconium oxide and silicon dioxide is 2:3.5:2:0.8: 0.8.

It can be seen from comparison of examples 1 to 6 and examples 7 to 9 with comparative examples 1 and 2 in combination with Table 8 that the organic composite filler further enhances the anticorrosive effect of the anticorrosive layer.

It can be seen from comparison of examples 1 to 9 and examples 10 to 12 with comparative examples 1 and 2 and from table 8 that the anti-cracking agent enhances the mechanical properties of the anti-corrosion layer, reduces cracking on the surface of the anti-corrosion layer, and further improves the anti-corrosion properties of the anti-corrosion layer.

As can be seen by comparing examples 1-12 and examples 13-15 with comparative examples 1 and 2 and by combining Table 8, the bactericide can reduce the propagation and growth of microorganisms in the corrosion-resistant layer and protect the corrosion-resistant layer.

Comparing examples 1 to 15 and examples 16 to 18 with comparative examples 1 and 2 and combining table 8, it can be seen that the dispersant improves the uniformity of the raw materials in the anti-corrosion layer, increases the isotropy of the anti-corrosion layer, and further improves the anti-corrosion effect of the anti-corrosion photo album.

To sum up, the anticorrosion album of this application has better anticorrosion effect, can use in comparatively abominable environment, and life improves greatly.
