Embodiment 1

[0032] Example 1: Preparation and flame retardant application of self-healing superhydrophobic flame retardant coating on polyester surface

[0033]Soak polyester successively in PAH aqueous solution (5mg / mL, pH=10) and PA aqueous solution (30mg / mL, pH=5) for 30 minutes each, take out the substrate after each soak, wash the substrate with deionized water and wring it out Moisture in the substrate; dry in an oven at 60°C for 4 hours, and a flame-retardant film is prepared on the surface of the substrate.

[0034] Soak the dried flame retardant polyester in 5mg / mL CH 3 (CH 2 ) 13 -Poss in a dichloromethane solution for 3 minutes, and then dry to obtain a self-healing superhydrophobic flame-retardant polyester.

[0035] In this example, changing the solution concentration will not have a significant impact on the construction of the membrane, but if the solution concentration is too low and the solute is too small, it will be difficult to obtain a very good fireproof effect an...

Embodiment 2

[0038] Example 2: Preparation of self-healing superhydrophobic flame-retardant coating on the surface of linen and application of self-healing superhydrophobic

[0039] Soak the linen in PDDA aqueous solution (8mg / mL, pH=7) for 20 minutes, then soak in PSP aqueous solution (25mg / mL, pH=7) for 60 minutes, take out the linen after each soaking, and rinse with deionized water Wash the linen and wring out the moisture in the linen; then dry it in an oven at 60° C. for 4 hours to prepare a flame-retardant film on the surface of the linen.

[0040] Soak the dried flame retardant burlap in 3mg / mL CF 3 (CF 2 ) 7 (CH 2 ) 2 -POSS in a toluene solution for 5 minutes, and then dry to obtain a self-healing superhydrophobic flame-retardant burlap.

[0041] from image 3 a It can be seen that even after flame baking and carbonization blackening, the integrity of the yarn structure of the fabric can still be maintained, in the enlarged SEM image ( image 3 In b), it can be seen that th...

Embodiment 3

[0043] Example 3: Preparation method of self-healing superhydrophobic flame-retardant coating Applying a composite dual-principle flame-retardant system to cotton cloth

[0044] Soak the cotton cloth in PEI aqueous solution (8mg / mL, pH=9), PSP and MMT composite aqueous solution (PSP concentration is 25mg / mL, pH=7, MMT is 5% of the mass of PSP) each for 20 minutes, each After soaking for the first time, take out the cotton cloth, wash the cotton cloth with deionized water and wring out the water in the substrate; dry it in an oven at 50°C for 5 hours, and prepare a flame-retardant film on the surface of the cotton cloth.

[0045] Soak the dried flame retardant substrate in 6mg / mL C 8 h 17 -Poss in a dichloromethane solution for 10 minutes, and then dry to obtain a self-healing superhydrophobic flame-retardant cloth.

[0046] In the composite system of PSP and MMT, there is both an intumescent flame retardant mechanism and a physical barrier effect of MMT. When the preparation...

Abstract

The invention relates to a production method of a self-repairing super-hydrophobic flame retardation coat layer, and belongs to the technical filed of production self-repairing super-hydrophobic flame retardation coat layers. The method comprises the following steps: a self-extinguishing flame retardation coat layer is made through a simple technology, and a self-repairing super-hydrophobic film is used to protect the flame retardation function easily destroyed by water. The method comprises the steps of substrate processing, solution preparation and three-layer film assembling. The substrate is not restricted by the size or shape of a fabric, and is suitable for various common fabrics. Terylene is modified with the self-repairing self-hydrophobic flame retardation coat layer, only 10cm of the fabric is blackened after the obtained fabric is ignited and burns for 12s, and the remaining portion of the fabric is completely not influenced by flame. The contact angle of the modified fabric is 160DEG, and the super-hydrophobicity can be rapidly restored after being destroyed. The method used in the invention has simple program, has the advantages of long acting and energy saving, can be used in various fabrics, and is expected to be widely applied in the fields of packaging, home finishing and buildings.

Description

technical field [0001] The invention belongs to the technical field of preparation of self-repairing superhydrophobic and flame-retardant coatings, and specifically prepares a self-extinguishing flame-retardant coating with a simple method, and uses the self-repairing superhydrophobic function to protect a flame-retardant film that is easily damaged by water. A method for preparing a self-healing superhydrophobic flame-retardant coating capable of prolonging the service life of the superhydrophobic coating and the flame-retardant coating is provided. Background technique [0002] Fabric has a wide range of applications in daily life. It can be seen in many aspects such as clothing and home packaging materials. However, the highly flammable characteristics of fabric deeply trouble us and greatly limit its application. Flame retardant treatment of flammable materials can effectively delay the flame spread and even prevent the material from being ignited. Recently, many studie...
