Embodiment 1

[0085] Embodiment 1: synthetic example 1

[0086] At room temperature, 58 g of acetone was added as a solvent into a 500 ml reaction kettle equipped with a stirrer, a thermometer, a reflux condenser, a constant pressure funnel and a nitrogen replacement device. Turn on the stirring, and mix 10.5g of fluorine-containing monomer (CF 3 (CF 2 ) 3 CH 2 CH 2 OCOC (CH 3 )=CH 2 ) into the reactor. Then add 0.5g urea heterocyclic compound hydroxyethyl ethylene urea and 1.78g methacryloxypropyltrimethoxysilane containing double bonds, then 7.9g butyl acrylate and 3.4g glycidyl methacrylate After the esters are mixed, slowly drop them into the reaction kettle with a constant pressure funnel. Then 0.14g of dodecyl mercaptan was diluted with a small amount of acetone solvent and slowly dropped into the reactor from a constant pressure funnel. Next, use a small amount of acetone as a solvent to dissolve 0.74g of azobisisobutyronitrile, heat to 50-85°C to promote the dissolution pro...

Embodiment 2

[0087] Embodiment 2: synthetic example 2

[0088] At room temperature, 30 g of acetone was added as a solvent into a 500 ml reaction kettle equipped with a stirrer, a thermometer, a reflux condenser, a constant pressure funnel and a nitrogen replacement device. Open stirring, under low speed, the fluorine-containing monomer (CF) of 49g 3 (CF 2 ) 5 CH 2 CH 2 CH 2 OCOC (CH 3 )=CH 2 ) into the reactor, then add 0.77g urea heterocyclic compound pseudothiohydantoin containing double bonds and 2.47g methacryloxypropylmethyldimethoxysilane, then add 15.3g of formazan After mixing ethyl ethyl methacrylate and 8.9 g of isobornyl methacrylate, they were slowly dropped into the reaction kettle with a constant pressure funnel. Then 0.2 g of mercaptoethanol was diluted with a small amount of acetone solvent and slowly dropped into the reaction kettle from a constant pressure funnel. Next, use a small amount of acetone as a solvent to dissolve 0.74g of azobisisobutyronitrile, heat ...

Embodiment 3： Synthetic example 3

[0090] At room temperature, 60 g of acetone was added as a solvent into a 500 ml reaction kettle equipped with a stirrer, a thermometer, a reflux condenser, a constant pressure funnel and a nitrogen replacement device. Start stirring, under low speed, the fluorine-containing monomer (CF) of 23g 3 (CF 2 ) 3 CH 2 CH 2 OCOCH=CH 2 ) into the reaction kettle, then add 0.5g urea heterocyclic compound α-(2-furanoyl) ureidophenylacetic acid and 2.465g methacryloxypropylmethyldiethoxysilane containing double bonds, Then, 11.18 g of dimethylaminoethyl methacrylate was slowly dropped into the reaction kettle with a constant pressure funnel. Then, 0.12 g of mercaptoethanol was diluted with a small amount of acetone solvent and slowly dropped into the reaction kettle through a constant pressure funnel. Next, use a small amount of acetone as a solvent to dissolve 0.74g of azobisisobutyronitrile, heat to 50-85°C to promote the dissolution process, and add it to a constant pressure funn...

Abstract

The invention relates to a waterproof oil-proof agent for paper products and a preparation method and application thereof. The waterproof oil-proof agent for the paper products is formed by copolymerization of a fluorine-containing monomer, a silane coupling agent and an acrylic monomer. The waterproof oil-proof agent for the paper products can be dispersed and dissolved in water, is environmental-friendly, has high stability, has a small addition volume in the paper products, and has excellent waterproof and oil-proof effects.

Description

technical field [0001] The invention relates to a polymer of fluorine-containing chemicals, in particular to a waterproof and oil-repellent agent for paper products and its preparation method and application. Background technique [0002] With people's emphasis on environmental protection in recent years, more and more products are required to reduce pollution or even be pollution-free, which has also led to the replacement of hard-to-degrade plastic products by paper products. The amount of paper products and their application range are in the Increasingly, it is widely used in packaging fields such as catering, food, and daily necessities, and in these fields, paper products are usually required to have waterproof and oil-proof properties. [0003] In the domestic and foreign papermaking industry and paper processing industry, the surface of paper products is usually covered with a polymer layer such as polyethylene film (commonly known as lamination or plastic coating) or...
