Embodiment 1

[0075] To aid in the development of corrosion-resistant containers for use as packaging for corrosion-sensitive materials such as automotive parts, three corrosion-resistant materials (in this case vapor corrosion inhibitors) were compared when sprayed to the interior of corrugated packaging , and with untreated containers and only use such as NTIC (Northern Technologies International Corp.) with the trademark Containers sold in commercially resistant plastic bags were compared. Carbon steel (C1020) and aluminum (AL 6061) corrosion coupons were placed in each sealed container in an environmental chamber at 90% relative humidity / 100°F for two weeks and then examined using an optical microscope. The result was that the liquid preservative treatment gave carbon steel a significant improvement in corrosion resistance compared to untreated containers and those coupons placed in airtight plastic bags. Given this exposure, the aluminum coupons did not show any corrosion.

Embodiment 2

[0091] test steps

[0092] A one cubic foot corrugated container was obtained to hold the blockage block (BUB) processed according to the following method. The BUB is a laminated structure of three or more walls, multiple layers of corrugated cardboard for shock absorbing automotive parts. In this study, only the upper surface (2.75 inches x 10 inches) of the BUB that was in direct contact with the corrosion coupons was treated.

[0093] Using a conventional paint roller (3 inch wide foam with 3 / 8 inch thick nap) the exposed side of the blockage block (BUB) was subjected to several different chemical treatments at doses measured using a balance. The minimum low, medium and high doses were applied to the top exposed surface of the BUB and then dried overnight under TAPPI standard conditions (50% relative humidity, 73°F). See Table 2 for the dosage of each treatment chemical applied to the BUBs.

Abstract

The present invention relates to an anticorrosive paper or paperboard substrate, as well as methods of making and using the same.

Description

[0001] This application claims priority benefit under 35 U.S.C. §119(e) to U.S. Provisional Patent Application 60 / 731,897, filed October 31, 2005, which is incorporated by reference in its entirety. technical field [0002] The present invention relates to preservative paper or paperboard substrates, and methods of making and using them. Background technique [0003] The international transport of corrosion-sensitive items in a variety of aqueous atmospheres is a very large and lucrative commercial market. To enable corrosion-sensitive items to withstand this environment, which fluctuates widely in temperature and moisture content (eg, relative humidity), the item can be coated with a corrosion-resistant material that can help reduce the item's susceptibility to corrosion. However, this coating applied directly to the item is messy and / or can compromise the ultimate function of the item, as can itself corrode the item. [0004] Examples of corrosive environments are those w...
