Problems solved by technology

[0005] However, in the current technology, the moisture resistance and oil repellency of the fabric cannot be fully expressed, so that the tensile strength of the fabric is easily reduced due to moisture in the application of the material, and it is easy to be damaged; because of poor oil repellency, the fabric is in use The process is polluted by oil, which leads to unsightly packaging or use, causing unnecessary losses; at the same time, cloth materials are flammable, and fire hazards must be prevented at all times during storage and use; for food in daily life The use of packing tape and the contact of a large number of living things will easily form a microbial adsorption layer on the surface of the cloth, which will affect human safety and health
[0006] In the currently disclosed technology, there is a modification of the cloth, through the dehydration c

Embodiment 1

[0036] A method for preparing a hydrophobic, oleophobic and antibacterial coating on the surface of a fabric material, the selected base material is cloth, specifically comprising the following steps:

[0037]1. Pretreatment: The base material is ultrasonicated for 5 minutes at room temperature with a surface eluent. The composition of the surface eluent is: sodium bicarbonate (1.5%), ethanol (10%), fatty alcohol polyoxyethylene ether sodium sulfate ( 7.5 w / %), sodium dodecylbenzenesulfonate (8w / %), cocoic acid diethanolamide (0.6w / %), pure water (72.4%); then rinse the surface with ultrapure water, and then place Soak in strong alkaline electrolytic water for 1min. The components of the strong alkaline solution are: NaOH (0.5%), sodium bicarbonate (1%), sodium phosphate (2%), ethanol (6.5%), pure water (90%) . Take it out and rinse the surface with ultrapure water, then soak it in 40°C ethanol solution for 5 minutes, finally rinse it with ultrapure water, put it in an oven a...

Abstract

The invention discloses hydrophobic, oleophobic and antibacterial coating for the surface of a textile material. The hydrophobic, oleophobic and antibacterial coating is prepared from the following components according to the mol ratio: the ratio of methyltriethoxysilane to perfluorooctyltriethoxysilane to modified nano silicon dioxide to water is (3 to 4) to (4 to 5) to (3 to 4) to (7 to 9); thehydrophobic, oleophobic and antibacterial coating further contains ethyl lauroyl arginate hydrochloride which accounts for 0.1 to 5 weight percent of the coating. According to the hydrophobic, oleophobic and antibacterial coating, a cloth material is washed through a specific pre-treatment technology and dip-coating of the coating is carried out; curing treatment is carried out by adopting a specific technology to obtain a hydrophobic, oleophobic and antibacterial coating layer. The hydrophobic, oleophobic and antibacterial coating layer provided by the invention has the advantages of good adhesion force, strong self-cleaning capability, strong hydrophobic and oleophobic performance, flame-retarding performance and antibacterial performance, is applicable to various cloth materials and hasan extremely strong self-protection capability; the surface of cloth has hydrophobic and oleophobic characteristics and the pollution-resisting property can be effectively enhanced; the hydrophobic,oleophobic and antibacterial coating has a relatively great application prospect.

Description

technical field [0001] The invention belongs to the technical field of material surface modification, and more specifically relates to a method for preparing a hydrophobic, oleophobic and antibacterial coating on the surface of a fabric material. Background technique [0002] While the extensive use of existing petroleum-based packaging materials brings convenience to people's lives, it also produces a series of negative effects, namely, environmental pollution caused by packaging waste and the intensified consumption of non-renewable petroleum resources. For this reason, biomass green environmental protection materials are gradually being developed and utilized by researchers. Cloth materials, as a kind of biomass materials, have unique advantages in terms of economic benefits and environmental protection benefits, and there are many kinds of fabrics, and the price is low for the public. Accepted, from its production to the end of its life, is pollution-free and pollution-f...
