Paper and paperboard surface finishing agent

Abstract

The invention relates to a paper and paperboard surface finishing agent. The paper and paperboard surface finishing agent contains 10-25% of linseed oil, 3-7% of sodium hydroxide, 8-10% of calcium hydroxide, 10-15% of addition polymerization resin, 5-10% of alkene unsaturated acid, 10-17% of triethanolamine butyraldehyde, 10-15% of tert-amyl methyl ether, 12-25% of isobutanol, 5-15% of polyoxyethylene nonylphenol ether and 10-25% of a water-soluble cellulose derivative, and the water-soluble cellulose derivative is composed of an etherified sulfomethyl group and an acidified sulfoethyl group. A molar ratio of the etherified sulfomethyl group to the acidified sulfoethyl group is 1:2-1:4. The water-soluble cellulose derivative has the dual effects of moisture resistance and mildew resistance, and has a wide, efficient and lasting sterilization and inhibition ability on moulds and yeasts.

Description

technical field [0001] The present invention relates to a manufacturing coating, and more particularly to a surface finishing agent for paper and cardboard. Background technique [0002] Microorganisms widely exist in nature. Usually, the natural conditions suitable for mold reproduction and growth are the temperature of 23 ℃ ~ 38 ℃ and the relative humidity of 85% ~ 100%. , cardboard, etc. are suitable for the growth of mold, and produce various metabolites of enzymes, acids and toxins, thus affecting the appearance and quality of items, and polluting the environment, endangering the growth of animals and plants and human health, if ordinary decorative coatings are used , it will be eroded to varying degrees by mold, and mold will erode the paper coating coating more seriously, and the coating after being corroded by mold will fade, stain, fall off or have holes. Therefore, the use of mildew-proof paper and cardboard surface finishing agent is one of the effective meas...

Problems solved by technology

[0002] Microorganisms widely exist in nature. Usually, the natural conditions suitable for the growth of molds are temperature 23°C-38°C and relative humidity 85%-100%. This is on the surface of paper, as well as partitions and ceilings of constant temperature and constant humidity workshops in other areas. , cardboard, etc. are suitable for the growth of mold, and thus produce various metabolites of enzymes, acids and toxins, which affect the appearance and quality of items, pollute the environment, endanger the growth of animals and plants and human health. If ordinary decorative coatings are used , it will be corroded by mold to varying degrees, and mold is more serious for the erosion of paper coating coatings. After being corroded by mold, the coating will fade, stain, fall off or have holes.
