Embodiment 1

[0024] Prepare the coating glue according to the following ratio:

[0025]

[0026] Add the raw materials except the thickener in the formula amount in sequence in the container, stir evenly with a disperser mixer, the stirring speed of the disperser mixer is 1200 rpm, after filtering, add a thickener to adjust the viscosity to 4000apm.s, and obtain a coating glue , after filtering again, pack.

Embodiment 2

[0028] Prepare the coating glue according to the following ratio:

[0029]

[0030]

[0031] Add the raw materials except the thickener in the formula amount in sequence in the container, and stir evenly with a dispersing mixer. The stirring speed of the dispersing mixer is 1500 rpm. After filtering, add a thickener to adjust the viscosity to 6000apm.s to obtain a coating glue. , after filtering again, pack.

Embodiment 3

[0033] Prepare the coating glue according to the following ratio:

[0034]

[0035]

[0036] Add the raw materials except the thickener in the formula amount in sequence in the container, and stir evenly with a dispersing mixer. The stirring speed of the dispersing mixer is 1800 rpm. After filtering, add a thickener to adjust the viscosity to 8000apm.s to obtain a coating glue. , after filtering again, pack.

[0037] The present invention is a water-based polyurethane synthetic leather foam coating glue used in the production of water-based ecological synthetic leather. The coating glue has the advantages of good stability and convenient use, and its application in production reduces the technical threshold of water-based synthetic leather enterprises. The process of producing synthetic leather with water-based polyurethane synthetic leather foaming glue is simple and easy to operate. The foamed synthetic leather produced with this foaming glue has excellent scratch resi...

Abstract

The invention discloses a formula of waterborne polyurethane synthetic leather intumescent coating glue. The waterborne polyurethane synthetic leather intumescent coating glue is prepared from 13.5%-87.5% of waterborne polyurethane emulsion, 3%-20% of filling agent, 2%-8% of ammonium stearate emulsion, 1%-5% of modifier, 1%-10% of anti-sticking agent, 0.5%-2% of ammonium hydroxide, 1%-10% of anti-sediment agent, 0.5%-3.5% of antistatic agent, 1%-5% of mould-proof antibacterial agent, 0.5%-4% of penetrant, 0.5%-2% of foaming agent, 0%-10% of water-based colour paste, 1%-4% of flatting agent and 0.5%-3% of thickening agent. A process comprises the steps that the raw materials except for the thickening agent are stirred to be uniform, filtering is carried out, the thickening agent is added to adjust the viscosity, and after filtering is carried out again, packaging is carried out. The waterborne polyurethane synthetic leather intumescent coating glue is good in stability and convenient to use, synthetic leather produced through the intumescent coating glue has excellent scratching resistance, wear resistance, waterproofness, breathability and low-temperature bending resistance, the process is simple, and environmental protection performance is good.
