Embodiment 1

[0028] The preparation method of anti-pollution heat-insulating paint for fabric of the present invention, concrete steps are as follows:

[0029] 1) Mix microcrystalline cellulose and concentrated sulfuric acid solution with a mass percent concentration of 50% at a weight ratio of 1:20, and ultrasonically treat at 50-55°C for 1 hour at an ultrasonic frequency of 50kHz and 400W to obtain a milky white suspension. Then the suspension was centrifuged at 1200r / min until the supernatant was colloidal, and the colloid A was collected for use;

[0030] 2) Mix 20mL of silica sol, 80mL of nitric acid aqueous solution (5% concentration by mass) and 320mL of ethanol and stir until a uniform mixed solution is formed; In the butanol mixture; ultrasonically stir at 50-55°C for 0.5h at an ultrasonic frequency of 50kHz and a power of 400W, add dropwise 40mL of ammonia water (10% by mass), and colloid B appears;

[0031] 3) The above colloid A, colloid B and KAl 2 [AlSi 3 o 10 〔OH〕 2 The...

Embodiment 2

[0034] Solution A, colloid B, KAl in the preparation of composite powder in step 3) 2 [AlSi 3 o 10 〔OH〕 2 The powders are mixed with a mass ratio of 1:1:1.3.

[0035] The percentage by weight of each composition in the coating in step 4) is: acetone 30%; Polybenzimidazole 1%; Polyacrylate 9%; KAl 2 [AlSi 3 o 10 〔OH〕 2 Composite powder 23%, polyethylene glycol 4%, the rest is polyurethane.

[0036]Other preparation methods are the same as in Example 1.

Embodiment 3

[0038] Solution A, colloid B, KAl in the preparation of composite powder in step 3) 2 [AlSi 3 o 10 〔OH〕 2 The powders are mixed with a mass ratio of 1:1:1.2.

[0039] The percentage by weight of each composition in the coating in step 4) is: acetone 25%; Polybenzimidazole 0.7%; Polyacrylate 7%; KAl 2 [AlSi 3 o 10 〔OH〕 2 Composite powder 20%, polyethylene glycol 3%, the rest is polyurethane.

[0040] Other preparation methods are the same as in Example 1.

Abstract

The invention provides an antifouling heat-insulating paint for fabrics and a preparation method thereof. The fabric paint has good heat insulation and strong stain resistance. The preparation method has simple process, low production cost and is suitable for industrialized production. The weight percent of each component in the anti-pollution heat-insulating coating for fabrics is: acetone 20-30%; polybenzimidazole 0.5-1%; polyacrylate 6-9%; KAl2 [AlSi3O10] [OH] 2 composite powder 18-23%, polyethylene glycol 2-4%, and the rest is polyurethane.

Description

technical field [0001] The invention belongs to the field of fabrics, and relates to an anti-aging heat-insulating fabric coating for fabrics and a preparation method thereof. Background technique [0002] Application No. CN200510042891.8 relates to a nano anti-fouling and anti-ultraviolet coating textile, clothing and processing technology. The nano-anti-fouling and anti-ultraviolet coated textiles and clothing are made of nano-composite materials for impregnation coating, and the processing technology includes 1. Pretreatment of fabrics and clothing; 2. Preparation of nano-anti-fouling and anti-ultraviolet finishing agent solution; 3. .Nano anti-fouling and anti-ultraviolet finishing and infiltration process; 4.Drying and baking. Preparation of nano-antifouling and anti-ultraviolet finishing agent solution: prepare nano-anti-fouling and anti-ultraviolet finishing agent according to 3-10% of the weight of the fabric, add water to prepare a solution of nano-anti-fouling an...
