Problems solved by technology

[0005] Judging from the situation introduced in the above literature, the vapor phase corrosion inhibitors with corrosion inhibition ability for zinc materials are either highly toxic or not ideal in antirust effect; or the raw materials are rare, which makes the production cost higher; some corrosion inhibitors are in In the process of production and application, a large amount of organic solvents are required, which not only causes difficulties in production, but also causes environmental pollution
Therefore, some vapor phase anti-rust packaging materials for zinc materials are not satisfactory so far, which is incompatible with the rapid development of today's society.

Embodiment 1

[0016] Dissolve 8 parts of hydroxysuccinic acid and 15 parts of 4-oxazepine in 242 parts of ionized water in batches, fully stir at 25°C and 0.1Mpa pressure to make the reaction complete, and then add the concentration of 5 parts of 48wt% PVA are made into a coating solution, which is coated on base paper and non-woven fabrics according to the above-mentioned method to make special vapor-phase antirust paper for galvanizing and special vapor-phase antirust non-woven fabric for galvanizing.

Embodiment 2

[0018] The quality is that 12 parts of hydroxysuccinic acid and 25 parts of 4-oxazepine are dissolved in 125 parts of deionized water, and fully stirred, so that the reaction is complete, and the concentration is added after 7 parts of 48wt% PVA, so that Coating solution, coated on the plastic film of polyolefin as the moisture-proof and anti-permeation layer, the skeleton material layer is polyolefin braid, the linking material is the same polyolefin resin, and the carrier material is anti-rust base paper or non-woven fabric. The composite material is processed into special galvanized boned vapor phase antirust paper and boned antirust non-woven fabric.

Embodiment 3

[0020] Purified solid VPI-PM whose mass is 10 parts of hydroxysuccinic acid and 20 parts of 4-oxazepine reaction product, take 20 parts of VPI-PM by mass, particle size is 0.5~5μm CaCO 3 60 parts, 10 parts of paraffin oil, 0.3 parts of dioctyl phthalate, and 0.5 parts of 2.6-di-tert-butyl-p-cresol were mixed uniformly to prepare the VPI-PM carrier. Add 10 parts of VPI-PM carrier to 100 parts of low-density polyethylene according to the mass ratio, and blow mold it into a film to obtain a special galvanized anti-rust plastic film with bones.

[0021] 5 samples were taken altogether of the vapor phase antirust paper special for galvanizing, the vapor phase antirust nonwoven fabric, the boned gaseous phase antirust paper, the boned gaseous phase antirust cloth and the antirust plastic film obtained in Examples 1 to 3. Performance tests, the results are listed in Table 1

Abstract

The invention discloses a vapour phase rust inhibitor VP1-PM special for zinc product and the production method of gas phase rust-preventive packaging material for galvanizing. The said VP1-PM is reaction product of malic Acid with morpholine, has unique gas phase inhibitor action to zinc product. Gas phase rust-preventive paper, gas phase rust-preventive non-woven fabric, framed gas phase rust-preventive paper, framed gas phase rust-preventive non-woven fabric, gas phase rust-preventive plastic film special for galvanizing can apply to long-term seal and temporary rust prevention of all kinds of galvanizing products from galvanizing bolt, screw cap, to heavy galvanizing coiled material, strip and sheet. The said gas phase rust-preventive packaging material for galvanizing has a good effect on rust prevention, long term rust prevention period, which is convenient for usage, and safe.

Description

technical field [0001] The invention relates to a vapor phase corrosion inhibitor morpholine malate and a special vapor phase antirust packaging material for galvanizing. Background technique [0002] In March 2003, at the American Society of Corrosion Engineers (NACE) Corrosion / 2003 academic annual meeting and exhibition held in San Deigo, USA, it was clear that the development of new, efficient and low-toxic gas phase corrosion inhibitors is the key to the development of gas phase corrosion inhibition technology ( Materials Protection. 2004VOL.37NO.1, 62). [0003] Since the 1950s, people have been making unremitting efforts to find high-efficiency, low-toxicity gas-phase corrosion inhibitors. In particular, the former Soviet Union Pris proposed that dicyclohexylamine nitrite and dicyclohexylamine have carcinogenic effects in 1958. And on March 21, 1975, held in Wuhan City Science and Technology Commission (Professor Chen Minhui of Hubei Medical College "About the Toxicit...
