Problems solved by technology

In the beginning, polystyrene, polypropylene resin plastics, polyethylene, polypropylene, and polyvinyl chloride packaging films were commonly used to achieve oil-proof effects, but these are polymer materials that degrade extremely slowly in nature. They meet the oil-proof requirements of the packaging, but the discarded plastic packaging materials after use have caused great pollution to the human environment

Abstract

The invention provides a compound oil-proofing agent for paper and a preparation method of the compound oil-proofing agent. The preparation method comprises the following steps of (1) mixing cationic starch with 90-120 parts of deionized water, heating to 90-95 DEG C, and stirring; (2) cooling to the room temperature, adding carboxymethylcellulose and waterborne polyurethane, and stirring at the revolving speed of 400-600 r / min; (3) adding chitosan, acetic acid and the rest of the deionized water, and stirring at the revolving speed of 700-1000 r / min; (4) heating to 80-100 DEG C, adding tetraethoxysilane, propylene ester of fatty acid, sodium dodecyl benzene sulfonate, sodium stearyl lactate, ammonium fatty alcohol polyoxyethylene ether sulfate, sodium diacetate and absolute ethyl alcohol, and stirring at the revolving speed of 600-800 r / min for 10-30 minutes; and (5) cooling to the room temperature to obtain the compound oil-proofing agent. By the means of the compound oil-proofing agent for paper, the oil-proofing property and the strength property of the paper are greatly improved, and the compound oil-proofing agent has a quite excellent oil proofing effect.

Description

technical field [0001] The invention relates to the field of paper-making auxiliary agents, in particular to a composite oil-repellent agent for paper and a preparation method thereof. Background technique [0002] Paper, plastic, metal, and glass are known as the four pillars of modern packaging materials, among which paper and plastic are cheap, have a wide range of raw materials, are lighter and easier to carry than metal and glass, have good printing performance, and are easy to transport, so Widely used in daily life and industrial production. With the rapid development of the economy, the amount of packaging materials is increasing rapidly. At the same time, due to the different properties of products, production methods, and application fields, packaging materials need to have different functions, including moisture-proof, oil-proof, and mildew-proof functions. characteristic. Among them, the feature of oil-proof packaging is that it can meet the requirements of pac...
