Problems solved by technology

However, fluorocarbon oil and water repellent itself also has a series of problems such as emulsion stability, emulsifier pollution and controllable preparation. In addition, when paper is coated with oil and water repellent, it involves the process of coating and drying, which has great impact on energy consumption. There are certain disadvantages in terms of utilization and environmental protection

Embodiment 1

[0025] A preparation method of plasma-induced fluorocarbon oil-proof and waterproof paper, the steps are as follows:

[0026] First, add 0.1mmol / L azobisisobutyronitrile to hexafluorobutyl methacrylate, and then dip the paper in it for 0.1h, then treat the paper with a low-pressure glow discharge plasma generator, and the plasma The processing conditions of the device are: air pressure 10Pa, processing power 20W, processing time 1min. After the reaction, the unreacted monomers and homopolymers were removed by soaking with acetone solvent for 1 hour, and dried at 100°C for 10 minutes to obtain fluorocarbon oil-proof and waterproof paper.

[0027] The fluorocarbon oil-proof and waterproof paper obtained in this embodiment has a contact angle of 101° to water and a contact angle of 84° to glycerin.

Embodiment 2

[0029] A preparation method of plasma-induced fluorocarbon oil-proof and waterproof paper, the steps are as follows:

[0030] First, after immersing the paper in dodecafluoroheptyl methacrylate (without adding oily initiator) for 2 hours, the paper is treated by a low-pressure glow discharge plasma generator. The treatment conditions of the plasma device are: air pressure 200Pa , processing power 100W, processing time 20min. After the reaction, immerse in Freon 113 solvent for 1 hour to remove unreacted monomers and homopolymers, and dry at 120°C for 10 minutes to obtain fluorocarbon oil-proof and waterproof paper.

[0031] The fluorocarbon oil-proof and waterproof paper obtained in this embodiment has a contact angle of 125° to water and a contact angle of 107° to glycerin.

Embodiment 3

[0033] A preparation method of plasma-induced fluorocarbon oil-proof and waterproof paper, the steps are as follows:

[0034] Firstly, the paper is subjected to plasma radical induction treatment in a low-pressure glow discharge plasma device, and the treatment conditions are: air pressure 100Pa, treatment power 50W, treatment time 10min. Then, quickly immerse the paper in dodecafluoroheptyl methacrylate (adding 0.5mmol / L azobisisobutyronitrile) to carry out graft copolymerization reaction. After 0.1h of reaction, soak it with Freon 113 solution for 1h to remove unreacted Monomer and homopolymer were dried at 110°C for 20 minutes to obtain fluorocarbon oil-proof and waterproof paper.

[0035] The fluorocarbon oil-proof and waterproof paper obtained in this embodiment has a contact angle of 104° to water and a contact angle of 91° to glycerin.

Abstract

The invention introduces a preparation method of plasma-induced fluorocarbon oil-proof and waterproof paper. This method mainly involves the impregnation treatment process of fluorine-containing acrylate monomer and the plasma-induced treatment process. Initiate graft copolymerization reaction of paper to prepare fluorocarbon oil-proof and waterproof paper; ② First, the paper is induced by plasma to generate free radicals, and then impregnated in fluorine-containing acrylate monomers to undergo graft copolymerization reaction to prepare fluorocarbon oil-proof paper Waterproof paper; ③ First, the paper is immersed in fluorine-containing acrylate monomer for a certain period of time, and then the paper graft copolymerization reaction is initiated by plasma, and then immersed in fluorine-containing acrylate monomer, and the graft copolymerization reaction continues to occur. Preparation of fluorocarbon oil and water repellent paper. The contact angles of the fluorocarbon oil-proof and waterproof paper prepared by the invention to water and to glycerin can respectively reach 132° and 113°.

Description

technical field [0001] The invention belongs to the field of oil-proof and waterproof materials, in particular to a preparation method of plasma-induced fluorocarbon oil-proof and waterproof paper. Background technique [0002] Oil-proof and waterproof materials are widely used in manufacturing and daily life, especially oil-proof and waterproof materials based on paper, because of their special properties such as: biodegradability, raw material renewability, etc. Molecular materials, oil-proof and waterproof paper can be prepared by dipping paper into latex or treating with oil-proof and water-repellent agents. Fluorocarbon oil and water repellent is one of the important oil and water repellents. The preparation method of fluorocarbon oil and water repellent generally requires the preparation of fluorine-containing acrylic monomers by emulsion polymerization. Because the fluorocarbon oil and water repellent has C-F on its surface, it can endow the substrate with lower surf...
