Problems solved by technology

For the waterproof, oil-proof and anti-fouling finishing and care agents on the market, some key components are perfluorobutyl sulfonic acid PFBS, whose carbon-fluorine bond is the strongest organic single bond, stable chemical properties, and not easy to polarize, so it is neither Hydrophilic and non-lipophilic, waterproof, oil-proof and anti-fouling effect is better, however, perfluorobutane sulfonic acid PFBS S is too stable in chemical properties, hardly degrades, causes too much pollution to the environment, and has liver toxicity to the human body. Half-life in vivo is about 5 years
In addition, some products on the market contain fluorocarbon resins. Although these products have good waterproof, oil-proof and anti-fouling properties, these products have low high-temperature resistance and UV resistance, which affects the performance of the product.

preparation example Construction

[0081] The preparation method of silica-hyperbranched polyurethane composite is as follows:

[0082] (1) 3-aminopropylmethyldiethoxysilane modified silica:

[0083] Add 100 parts by weight of toluene and 5 parts by weight of silica into a three-necked flask, ultrasonically disperse for 30 minutes, stir vigorously, and add 1 to 2 parts by weight of 3-aminopropylmethyldiethoxysilane modified silica , 10ml of deionized water containing 1ml of triethylamine, reflux at 110°C for 6h, filter, wash with absolute ethanol, extract three times, dry in a vacuum oven for 24h to obtain 3-aminopropylmethyldiethoxysilane Modified silica.

[0084] (2) Silica-hyperbranched polyurethane composite:

[0085] Add 0.01g of 3-aminopropylmethyldiethoxysilane-modified silica synthesized above, 1-10g of hyperbranched polyurethane and 50ml of N,N-dimethylformamide into a three-necked flask, and stir well at room temperature Afterwards, after reacting at 30-60°C for 5-30 hours, settling and filtering i...

Embodiment approach 1

[0097] Embodiment 1: Embodiment 1 of the present invention provides a kind of spray-type surface waterproof, oil-proof and antifouling care agent, in parts by weight, it is characterized in that, at least comprises the following components:

[0098] 100 parts by weight of fluoropolymer;

[0099] 10-50 parts by weight of phenyl silicone oil;

[0100] 0.1-10 parts by weight of aliphatic hydrocarbons;

[0101] Wherein, the raw materials for the preparation of the fluorine-based polymer include at least one or a mixture of perfluoroalkyl acrylate monomers, silyl acrylate monomers, and m-trifluoromethylstyrene.

Embodiment approach 2

[0102] Embodiment 2: Same as Embodiment 1, the difference is that the weight ratio of the perfluoroalkyl acrylate monomer, silyl acrylate monomer, and m-trifluoromethylstyrene is (50-100) :(10~60):(1~5).

Abstract

The invention belongs to the technical field of surface treatment, and particularly discloses a mist-sprayed surface waterproof, oilproof and antifouling nursing agent. The mist-sprayed surface waterproof, oilproof and antifouling nursing agent is characterized by at least comprising, by weight, 100 parts of fluoric polymers, 10-50 parts of phenyl silicone oil and 0.1-10 parts of aliphatic series hydrocarbon, wherein raw materials for preparing the fluoric polymers comprise at least one or more of perfluoroalkylated acrylate monomers, silylation acrylic monomers and m-trifluoromethyl styrene. The mist-sprayed surface waterproof, oilproof and antifouling nursing agent has good waterproof, oilproof and antifouling performance.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a spray-type surface waterproof, oil-proof and anti-fouling treatment agent. Background technique [0002] At present, waterproof, oil-proof and anti-fouling finishing and care agents are more popular. When sprayed on the surface of the fabric, it can endow the surface of the substrate with waterproof, oil-proof and anti-fouling effects. For the waterproof, oil-proof and anti-fouling finishing and care agents on the market, some key components are perfluorobutyl sulfonic acid PFBS, whose carbon-fluorine bond is the strongest organic single bond, stable chemical properties, and not easy to polarize, so it is neither Hydrophilic and non-lipophilic, waterproof, oil-proof and anti-fouling effect is better, however, perfluorobutane sulfonic acid PFBS S is too stable in chemical properties, hardly degrades, causes too much pollution to the environment, and has liv...
