Problems solved by technology

Fabric coating is the fastest-growing and most extensive textile finishing technology in recent years. The coated fabric has the effects of leather feeling, high resilience, plump and soft hand feeling, etc., and is waterproof, breathable, moisture-permeable, and waterproof. With the continuous improvement of people's living standards, the requirements for the appearance, feel, strength and hardness of textiles are getting higher and higher, but the existing textile coating adhesives cannot meet the above requirements

Embodiment 1

[0035] The invention provides a kind of preparation method of textile coating glue, comprises the following steps:

[0036] S1. Add 26% water and 32.9% water-based polyacrylate resin to the dispersion kettle to dissolve the water-based polyacrylate resin in water to obtain a water-based polyacrylate resin solution, and then slowly and uniformly add 0.5% water-based polyacrylate resin to the dispersion kettle % pH adjuster to adjust the pH value of the aqueous polyacrylate resin solution so that the pH value of the mixed solution is 6 to 8, which is recorded as the first mixed solution;

[0037] S2. Stir the first mixed solution. At the same time, in the state of stirring, add 37% water-based polyurethane resin into the dispersion tank, and stir evenly, so that the water-based polyurethane is uniformly mixed in the water-based polyacrylate resin solution to obtain the second mixture;

[0038] S3. Add 1% polyoxyethylene ether and 0.1% silicone defoamer to the second mixed solut...

Embodiment 2

[0045] The invention provides a kind of preparation method of textile coating glue, comprises the following steps:

[0046] S1. Add 30% water and 24% water-based polyacrylate resin to the dispersion tank to dissolve the water-based polyacrylate resin in water to obtain a water-based polyacrylate resin solution, and then slowly and uniformly add 0.5% water-based polyacrylate resin to the dispersion tank % pH adjuster to adjust the pH value of the aqueous polyacrylate resin solution so that the pH value of the mixed solution is 6 to 8, which is recorded as the first mixed solution;

[0047] S2. Stir the first mixed solution. At the same time, under the state of stirring, add 43% water-based polyurethane resin into the dispersion tank, and stir evenly, so that the water-based polyurethane is uniformly mixed in the water-based polyacrylate resin solution to obtain the second mixture;

[0048] S3. Add 0.2% of anionic surfactant and 0.1% of silicone defoamer to the second mixed sol...

Embodiment 3

[0055]The invention provides a kind of preparation method of textile coating glue, comprises the following steps:

[0056] S1. Add 31% water and 28% water-based polyacrylate resin to the dispersion tank to dissolve the water-based polyacrylate resin in water to obtain a water-based polyacrylate resin solution, and then slowly and uniformly add 0.25% % pH adjuster to adjust the pH value of the aqueous polyacrylate resin solution so that the pH value of the mixed solution is 6 to 8, which is recorded as the first mixed solution;

[0057] S2. Stir the first mixed solution. At the same time, under the state of stirring, add 38% water-based polyurethane resin to the dispersion tank, and stir evenly, so that the water-based polyurethane is uniformly mixed in the water-based polyacrylate resin solution to obtain the second mixture;

[0058] S3. Add 0.6% polyoxyethylene ether and 0.5% modified polysiloxane emulsion to the second mixed solution, and stir evenly to obtain the third mix...

Abstract

The invention discloses a high hardness waterborne polyurethane fabric coating adhesive which is prepared from the following raw materials in percent by mass: 25-35% of water, 35-45% of waterborne polyurethane resin, 25-35% of waterborne polyacrylate resin, 1-10% of a sodium polyacrylate solution, 0.1-1% of a wetting agent, 0.1-0.5% of a defoamer, 0.5-1% of a pH regulator and 0.5-1% of a thickener. After a textile is coated with the fabric coating adhesive, the fabric coating product is high in seam slippage strength, hard and stiff in hand feeling and free of crease and fold. A preparation method is simple in process, low in cost and easy to popularize and apply.

Description

technical field [0001] The invention relates to textile products, in particular to a high-hardness water-based polyurethane textile coating glue and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, domestic and foreign markets have paid more and more attention to the research of textile ecology and the development of green textiles. The safety and ecology of textiles have become the contents that must be considered in the international trade of textiles. Especially in the past three years, on the one hand, there is a serious shortage of energy in the world, and on the other hand, the climate is obviously warming, coupled with the financial crisis, the world textile market has undergone great changes, and many new factors have emerged. The market has put forward stricter requirements for human safety and health and ecological environment protection. In order to adapt to the situation of low-carbon economy, the market has put...
