Embodiment 1

[0054] A moisture-proof enhancer for paper, prepared through the following steps:

[0055] (1) Dissolve 8g of ammonium persulfate in 80g of water and place it in the first high-level tank, mix 14g of monomer butyl acrylate and 7g of styrene and place it in the second high-level tank;

[0056] (2) Add 50g of acrylamide, 8.75g of dimethyl diallyl ammonium chloride, 3.5g of acrylic acid, and 506g of water into the reaction kettle, start stirring, heat up, and pass in nitrogen to remove oxygen, when the temperature rises to 65°C , add 1.4g of ammonium persulfate (dissolved in 5g of water in advance), and add 0.35g of sodium bisulfite (dissolved in 5g of water in advance) after 10 minutes to initiate polymerization and start self-heating; self-heating exceeds 90°C and must be cooled and kept at the temperature;

[0057] (3) After the self-heating of step (2) stops, start dripping the material in the first high-level tank and the second high-level tank, and drop simultaneously, the...

Embodiment 2

[0059] A moisture-proof enhancer for paper, prepared through the following steps:

[0060] (1) Dissolve 8.4g of ammonium persulfate with 80g of water and place it in the first high-level tank, mix 14g of monomer butyl acrylate and 17.5g of styrene and place it in the second high-level tank;

[0061] (2) Add 49.5g of acrylamide, 5.83g of dimethyldiallylammonium chloride, and 497g of water into the reaction kettle, start stirring, heat up, and pass in nitrogen to remove oxygen. When the temperature rises to 65°C, add over Ammonium sulfate 1.5g (dissolved in 5g water in advance), add 0.56g sodium bisulfite (dissolved in 5g water in advance) after 10 minutes to initiate polymerization and start self-heating; self-heating exceeds 90°C and must be cooled and kept at this temperature;

[0062] (3) After the above-mentioned steps stop heating, start dripping the materials in the first high-level tank and the second high-level tank, and drop them at the same time. The material in the s...

Embodiment 3

[0064] A moisture-proof enhancer for paper, prepared through the following steps:

[0065] (1) 10g of ammonium persulfate is dissolved in 80g of water and then placed in the first high-level tank, and the monomer butyl acrylate 14g and styrene 21g are mixed and then placed in the second high-level tank;

[0066] (2) Add 81.7g of acrylamide, 16.1g of dimethyl diallyl ammonium chloride, 5.6g of acrylic acid, 442g of water, and 0.63g of molecular weight inhibitor into the reaction kettle, start stirring, heat up, and pass nitrogen gas to remove Oxygen, when the temperature is raised to 65°C, add 1.5g of ammonium persulfate (dissolved in 5g of water in advance), and add 1.05g of sodium bisulfite (dissolved in 5g of water in advance) after 10 minutes to initiate polymerization, and start to heat up automatically; The temperature must be lowered to 90°C and maintained at this temperature;

[0067] (3) After the self-heating of step (2) stops, start dripping the material in the firs...

Abstract

The invention provides a moisture-proof enhancer for paper, which includes component A, component B and component C. In parts by weight, the component A includes the following raw material components: 2-20 parts of acrylamide, with unsaturated 0.01-8 parts of cationic monomers with double bonds, 0-5 parts of anionic monomers with unsaturated double bonds, 30-100 parts of water, 0.02-10 parts of oxidation initiators, 0.005-6 parts of reduction initiators, molecular weight inhibitors 0-5 parts; by weight, the B component includes the following raw material components: 1-20 parts of water, 0.1-10 parts of oxidation initiator, 0.1-8 parts of oily soft monomer, and 0.1-8 parts of oily hard monomer 8 parts; by weight, the C component includes the following raw material components: 0.1-6 parts of acrylamide, 0.01-5 parts of cationic monomers with unsaturated double bonds, and 0.5-10 parts of water. After the moisture-proof enhancer for paper of the present invention is applied to paper, the water-resistance performance, the burst index and the ring compression strength are all significantly improved.

Description

technical field [0001] The invention belongs to the technical field of fine chemical products, and relates to a moisture-proof enhancer for corrugated paper, a preparation method and application thereof. Background technique [0002] Corrugated cardboard is versatile, easy to manufacture, and can be recycled and reused, because of these many advantages, the application of corrugated paper has grown significantly. By the beginning of the 20th century, corrugated paper had been fully popularized, promoted and applied in the production and packaging of various commodities. Since the packaging container made of corrugated cardboard has its unique performance and advantages in terms of packaging beautification and protecting the built-in goods, corrugated paper has achieved great success in the competition with many other packaging materials, and has become a long-term use so far. It is one of the main materials for making packaging containers that is not declining and showing r...
