Embodiment 1

[0028] In a four-necked flask equipped with a stirrer, a thermometer, and a reflux tube, mix 2g of BPO initiator, 5g of acrylamide, 20g of vinyl silicone oil (1000cp), 6g of vinyl chloride propylene, 40g of octadecyl acrylate with 100g of solvent (a blend of ethyl acetate 50g and butyl acetate 50g) mixed evenly, and added dropwise to the reaction vessel at 80°C for 4 hours, then added 29g of dodecafluoroheptyl acrylate dropwise for 1 hour, and finally mechanically stirred and kept for reaction After 5 hours, a uniform solution viscous substance was obtained, which was the environmentally friendly flame-retardant and water-repellent agent for leather. After standing for two months, the solution does not stratify and has good stability. Take the waterproofing agent and bake it at 100°C for 4 hours without yellowing. Ignite the dried waterproofing agent with an open flame and remove the fire source. It has a certain flame retardant performance. Apply the water repellent solution...

Embodiment 2

[0030] In a four-necked flask equipped with a stirrer, a thermometer, and a reflux tube, 1.5g AIBN initiator, 15g hydroxyethyl acrylate, 10g vinyl silicone oil (1500cp), 3g vinylidene chloride propylene monomer, 50g hexadecane acrylate Mix 100g solvent (butanone) and 100g solvent (butanone) evenly, add dropwise to the reaction vessel at 90°C for 2 hours, then add 22g dodecafluoroheptyl acrylate dropwise for 2 hours, and finally mechanically stir and keep warm for 3 hours to obtain a uniform The solution viscous is the environmentally friendly flame retardant waterproofing agent for leather. After standing for two months, the solution does not stratify and has good stability. Take the waterproofing agent and bake it at 100°C for 4 hours without yellowing. Ignite the dried waterproofing agent with an open flame and remove the fire source. It has a certain flame retardant performance. Apply the water repellent solution to the leather finishing agent 2060E, add 2 g of water repel...

Embodiment 3

[0032] In a four-necked flask equipped with a stirrer, a thermometer, and a reflux tube, mix 1.5g of BPO initiator, 6g of hydroxypropyl acrylate, 12g of vinyl silicone oil (500cp), 4g of vinyl chloride, 60g of dodecyl acrylate with 100g The solvent (a blend of butanone 50g and butyl acetate 50g) was mixed evenly, and added dropwise to the reaction vessel at 85°C for 3 hours, then 18g of hexafluorobutyl acrylate was added dropwise for 1.5 hours, and finally mechanically stirred and kept for 4 hours. Finally, obtain a uniform solution viscous substance, which is the environmentally friendly flame-retardant and water-repellent agent for leather. After standing for two months, the solution does not stratify and has good stability. Take the waterproofing agent and bake it at 100°C for 4 hours without yellowing. Ignite the dried waterproofing agent with an open flame and remove the fire source. It has a certain flame retardant performance. Apply the water repellent solution to the ...

Abstract

The invention belongs to the field of leather finishing agents, and discloses an environment-friendly and flame-retardant waterproof agent for leather and a preparation method for the waterproof agent. The preparation method comprises the following steps: uniformly mixing an initiator, an acrylic ester monomer, vinyl silicone oil, a flame-retardant allyl vinyl monomer, a long-chain alkyl acrylate monomer and a solvent according to a proportion, adding dropwise a mixed solution into an 80 to 90 DEG C reactor for 2 to 4h, adding dropwise a fluorinated acrylate monomer for 1 to 2h, performing mechanical stirring and heat-preservation reaction for 3 to 5h, and performing cooling to obtain the environment-friendly and flame-retardant waterproof agent for the leather. The obtained waterproof agent is free of yellowing and demixing and high in stability; a formed waterproof agent film is flame-retardant, resistant to alcohol rubbing and persistent in waterproof performance, and has good application and environmental protection prospect, and a production process is simple.

Description

technical field [0001] The invention belongs to the field of leather finishing agents, and in particular relates to an environmentally friendly flame-retardant and water-repellent agent for leather and a preparation method thereof. Background technique [0002] With the improvement of people's consumption concept and consumption level, people place higher requirements on leather. In addition to keeping warm and covering the body, it should also be beautiful and comfortable. Environmental protection, flame retardancy and other functions. The current market waterproofing agents have problems such as poor stability and easy delamination. Some waterproofing agents contain PFOS / PFOA and other ingredients that are harmful to the human body and the environment, and are also bioaccumulative. Therefore, the new environmentally friendly and stable waterproofing agent has become a product with great development prospects in the current market. [0003] Fluorine-containing acrylate co...
