Embodiment 1

[0034] (1) Preparation of crosslinkable flame retardant fluorine-containing silicone oil:

[0035] Under nitrogen protection, 25g of perfluorobutylethylene as perfluoroalkylethylene, 35g of glycidyl methacrylate and 20g of allyl phosphate and 100g of hydrogen-containing silicone oil (molecular weight at 9000 Hydrogen-containing silicone oil with a hydrogen content of 0.8%) (Foshan Huagu Organic Silicon Co., Ltd.) was mixed to obtain a mixed solution 1;

[0036] 25g perfluorobutylethylene, 35g glycidyl methacrylate and 20g allyl phosphate were mixed with 0.25g Karstedt catalyst (1,3-divinyl-1,1,3,3-tetramethyldisiloxane Platinum (0), Pt, 2% xylene solution) were mixed and placed in an environment of 70°C for activation to obtain a mixed solution 2;

[0037] After activation, slowly drop the mixed solution 2 into the mixed solution 1; heat up to 100°C and react for four hours. The unreacted small molecules in the product were removed by suction filtration to obtain a cross-lin...

Embodiment 2

[0040] Under the protection of nitrogen, 35g of perfluoroalkylethylene, 45g of epoxy-containing substances and 28g of allyl phosphate were mixed with 200g of hydrogen-containing silicone oil to obtain a mixed solution 1;

[0041] Mix 35g of perfluoroalkylethylene, 45g of epoxy-containing substances and 28g of allyl phosphate with 8g of platinum catalyst and put them into an environment of 70°C for activation to obtain mixed solution 2;

[0042] After activation, slowly drop the mixed solution 2 into the mixed solution 1; heat up to 100°C and react for four hours. The unreacted small molecules in the product were removed by suction filtration to obtain a cross-linkable flame-retardant fluorine-containing silicone oil, and its infrared spectrum was as follows: figure 1 shown.

[0043] Among them, the perfluoroalkylethylene is perfluorohexylethylene, the epoxy-containing substance is allyl glycidyl ether, the allyl phosphate is allyl dimethyl phosphate, and the hydrogen-containi...

Embodiment 3

[0046] Under the protection of nitrogen, mix 30g of perfluoroalkylethylene, 15g of epoxy group-containing substances and 10g of allyl phosphate with 180g of hydrogen-containing silicone oil to prepare mixed solution 1;

[0047] Mix 30g of perfluoroalkylethylene, 15g of epoxy-containing substances and 10g of allyl phosphate with 5g of platinum catalyst and put them into an environment of 70°C for activation to obtain mixed solution 2;

[0048] After activation, slowly drop the mixed solution 2 into the mixed solution 1; heat up to 100°C and react for four hours. Remove unreacted small molecules in the product by suction filtration, cross-linkable flame retardant fluorine-containing silicone oil.

[0049] Among them, the perfluoroalkylethylene is perfluorohexylethylene, the epoxy-containing substance is allyl glycidyl ether, the allyl phosphate is allyl dimethyl phosphate, and the hydrogen-containing silicone oil has a molecular weight of 9000 and a hydrogen content of 0.35% hy...

Abstract

The invention discloses crosslinkable flame-retardant fluorine-containing silicone oil, a preparation method thereof and a flame-retardant release coating. The crosslinkable flame-retardant fluorine-containing silicone oil is characterized in that the structural formula of the crosslinkable flame-retardant fluorine-containing silicone oil is as shown in the following formula (I), and the crosslinkable flame-retardant fluorine-containing silicone oil has good flame retardancy.

Description

technical field [0001] The invention relates to the field of fluorine-containing silicone oil, in particular to a crosslinkable flame-retardant fluorine-containing silicone oil, a preparation method thereof and a flame-retardant release coating. Background technique [0002] Fluoropolymers have the characteristics of low surface free energy, super weather resistance, outstanding salt spray resistance, and a little stain resistance. In the 1980s, fluorine was first introduced into silicone. Fluorosilicone oil is a polysiloxane with fluorine-containing alkyl side chains. Its unique molecular structure endows fluorosilicone oil with superior high and low temperature resistance, excellent oxidation resistance and weather resistance. [0003] Fluorine-containing silicone oil is obtained by first hydrolyzing chlorosilanes containing fluorine-containing alkyl groups, and then performing ring-opening polymerization. In this process, a large amount of organic solvents will be used, ...
