Sponge with gas phase rust-proof layer and pressure-sensitive adhesive for multiple metal and its production method

Abstract

The present invention provides a multiple-metal gaseous phase rust-proofing pressure-sensitive adhesive sponge comprises an upper layer, a middle layer and a lower layer, the middle layer is a sponge layer, the upper layer is a hot melt adhesive, the lower layer is gas phase rust-preventing agent, its preparing process comprises, mixing phenylethene, butadiene or isoprene blocked copolymer, white oil or naphthenic oil, rosin or terpene resin, anti-oxidant, cyclohexylamine benzoate, amine benzoate and benzene-triazole, squeezing to obtain gas phase rust-preventing pressure-sensitive adhesive, (2) mixing starch gum liquid, cyclohexylamine benzoate, amine benzoate, benzene-triazole and grinding, (3) coating the hot melt pressure-sensitive adhesive and the gas phase antirusting agent homogeneously onto the two surfaces of sponge for air drying.

Description

technical field [0001] The invention relates to an antirust packaging material for metal and its metal products, in particular to a vapor phase antirust pressure-sensitive viscose sponge and a production method thereof. Background technique [0002] Metal and its metal products are easily corroded by the pollution of the atmosphere and other environments during storage and transportation, which seriously affects the quality of intermediate products and the life of metal products. At present, the main methods of anti-rust are as follows: one is to apply oil on the metal surface. When the metal product is used, the oil layer on the surface is difficult to deal with and causes pollution; the other is to wrap it with an anti-rust film. rust effect. When metal products are large in size, it is difficult to wrap them, especially for anti-rust between processes and military containers for weapons. It is difficult to achieve satisfactory anti-rust effect. Contents of the inventio...
