Problems solved by technology

[0007] Although in the above-mentioned patents, various waterproofing agents have been prepared in order to obtain waterproofing of the fabric, and different waterproofing treatment methods have been adopted, but their preparation process is complicated and the requirements are high, or the fabric needs to be impregnated first when using the waterproofing agent. Then heat and dry in an oven or hang it for a long time to achieve waterproof effect, not suitable for car beauty and daily household use

Embodiment 1

[0033] Weigh 0.03g of concentrated sulfuric acid, 0.4g of deionized water and 2g of ethyl orthosilicate into 10g of ethanol, raise the temperature to 50°C, and react for 1 hour; then add 1g of dodecyltriethoxysilane and 0.5g of Hydroxyfluorosilicone resin, reflux at 70°C for 0.5 hour, after cooling, add 90g of ethanol to dilute to prepare fabric coating agent.

[0034] Instructions:

[0035] Firstly, the floating dust on the fabric is cleaned and kept dry, and then the fabric coating agent prepared in this example is evenly sprayed on the surface of the fabric. After standing at room temperature for 30 minutes, the fabric has the effect of waterproof and antifouling.

Embodiment 2

[0037] Weigh 0.08g of concentrated hydrochloric acid (37%), 1g of deionized water, 0.3g of ethyl orthosilicate and 1.5g of methyl orthosilicate and add them to 20g of ethanol, raise the temperature to 50°C, and react for 1.5 hours; then add 0.5 g heptadecafluorodecyltriethoxysilane and 0.2g hydroxyfluorosilicone resin, reflux at 70°C for 0.5 hour, after cooling, add 80g ethanol for dilution to prepare fabric coating agent.

[0038] Instructions:

[0039] First, clean the floating dust on the fabric and keep it dry, then evenly spray the fabric coating agent prepared in this example on the surface of the fabric, and evenly heat it with a hair dryer for 5 minutes, and the fabric will have the effect of waterproof and antifouling.

Embodiment 3

[0041] Weigh 0.03g of concentrated hydrochloric acid (37%), 0.05g of glacial acetic acid, 2g of deionized water and 2g of propyl orthosilicate into 10g of ethanol, heat up to 50°C, and react for 1 hour; then add 0.8g of tridecafluoro Octyltriethoxysilane and 0.5g of hydroxyfluorosilicone resin were refluxed at 70°C for 1 hour, and after cooling, 85g of ethanol was added for dilution to obtain a fabric coating agent.

[0042] Instructions:

[0043] Firstly, the floating dust on the fabric is cleaned and kept dry, and then the fabric coating agent prepared in this example is evenly sprayed on the surface of the fabric. After standing at room temperature for 40 minutes, the fabric has the effect of waterproof and antifouling.

Abstract

The invention discloses a fabric film coating agent, which has the composition of silane, silicate ester, silicone, ethanol, acid catalyst and de-ionized water. The fabric film coating agent has the advantages that: the fabric film coating agent is sprayed on the surface of a fabric and is naturally dried or slightly heated, so that a flexible protection layer is formed on the surface of the fabric to isolate dirt and prevent the fabric from being polluted by fruit juice, coffee, tea, milk and water, original performance and handfeel of the fabric are not changed, and air permeability of the fabric is kept; and the fabric film coating agent can be widely used for automobile roofs, fabric seat covers, fabric seat cushions, fabric sofas, blankets, plush fabrics and the like.

Description

technical field [0001] The invention belongs to the field of textile functional finishing, and relates to a fabric coating agent and a preparation method and application method thereof. Background technique [0002] In daily life, various fabrics such as fabric sofas, fabric seats, cushions, carpets, etc. are easily polluted by fruit juice, coffee, tea, milk, water, etc. It is very difficult to clean, which seriously affects the appearance. In order to improve the stain resistance of fabrics, people carry out waterproof treatment to fabrics. At present, there are many kinds of fabric waterproofing agents, and the commonly used waterproofing agents mainly include organic silicon and organic fluorine. [0003] The Chinese patent (CN101100821A) uses silicon materials to modify the surface of cellulose and prepares cellulose materials with superhydrophobic properties. This method not only has a complicated preparation process, but also needs to impregnate the fiber material, a...
