Problems solved by technology

But the coloring material of current camouflage camouflage is mainly paint, and paint dyeing is generally used for the camouflage of fixed target, but it exists the problem of feel, rubbing fastness not good, and comfort is poor; In addition, existing camouflage fabric is parked in the open process , Sunlight is directly irradiated on the fabric, because the humidity can vary from 0 to 100%, and the combined effect of light (especially ultraviolet light), heat, and humidity will quickly destroy the dye on the fabric and cause the fabric to fade At the same time, it will destroy the fabric itself, resulting in a decline in strength, which will affect the practical performance and hydraulic performance of the fabric.
Moreover, the textiles used for direct coating are all interwoven by warp and weft yarns, and the surface of the fabric is extremely uneven. Direct coating will inevitably cause diffuse reflection of the coating film on light.
The existing technology is to calender the fabric first, flatten the warp and weft yarn interlacing points as much as possible, and then coat. The worse the peel strength between the coating film and the fabric

Embodiment 1

[0030]A coating process for camouflage tent cloth, comprising the following steps: the first step, using PA glue to prime the fabric base cloth; the second step, using PVC coating slurry to apply PVC white to the fabric base cloth after priming ; The third step is to carry out PU silver surface coating to the fabric base cloth after PVC whitening with PU silver paste. The PA glue includes PA coating glue, cross-linking agent, and solvent, and the weight ratio of PA coating glue, cross-linking agent, and solvent is 80-100:1-2:4-8. The weight ratio of the PA coating glue, crosslinking agent and solvent is 80:2:5. The crosslinking agent is polyisocyanate, and the solvent is ethyl acetate. The preparation process of the PA glue is as follows: add the solvent into the crosslinking agent and mix thoroughly, then add it to the coating glue and stir, add toluene while stirring to adjust the viscosity to 8000~10000mPa·S, stir well and let stand for 30min. The viscosity is adjusted to...

Embodiment 2

[0033] The difference from Example 1 is that the PA glue includes PA coating glue, crosslinking agent, and solvent, and the weight ratio of PA coating glue, crosslinking agent, and solvent is 100:2:8. The process parameters when using PA glue as the primer in the first step are: select a sharp-angle scraper, adjust the scraper angle to 125 degrees, adjust the magnetic force of the magnetic roller to 100%, control the temperature in the front area of ​​the oven to 80°C, and the temperature in the rear area to 120°C. ℃, drying time 35s. The PVC coating paste includes PVC resin, plasticizer and thermal stabilizer, and the weight ratio of PVC resin, plasticizer and thermal stabilizer is 100:100:4. The preparation process of the PVC coating slurry is as follows: first add a part of the plasticizer to the stearate and the white paint, stir well, then pour it into the mixer together with the PVC resin, then add the remaining plasticizer, stir well Finally, grind once with a three-ro...

Embodiment 3

[0035] The difference from Example 1 is that the PA glue includes PA coating glue, cross-linking agent, and solvent, and the weight ratio of PA coating glue, cross-linking agent, and solvent is 80:1:4. The process parameters when using PA glue in the first step are: select a sharp-angle scraper, adjust the scraper angle to 115 degrees, adjust the magnetic force of the magnetic roller to 90%, control the temperature in the front area of ​​the oven to 70 ° C, and the temperature in the rear area to 110 ° C. ℃, drying time 30s. The PVC coating slurry includes PVC resin, plasticizer and thermal stabilizer, and the weight ratio of PVC resin, plasticizer and thermal stabilizer is 100:100:0.5. The preparation process of the PVC coating slurry is as follows: first add a part of the plasticizer to the stearate and the white paint, stir well, then pour it into the mixer together with the PVC resin, then add the remaining plasticizer, stir well Finally, grind once with a three-roll mill...

Abstract

The invention provides a camouflage tent cloth coating technology. The technology comprises the following steps: 1, priming a fabric base cloth by PA glue; 2, carrying out PVC whitening of the primed fabric base cloth by a PVC coat; and 3, carrying out PU silver surface coating of the PVC-whitened fabric base cloth by a PU silver paste. The technology enables the fabric base cloth fabric to have a high light color fastness function, a high hydrostatic pressure resistance function and a high water repellency, and has the advantages of reasonableness and low economic cost.

Description

technical field [0001] The invention relates to the textile field, in particular to a coating process for a camouflage tent cloth. Background technique [0002] Among the existing outdoor coated textiles and military outdoor textiles, especially camouflage tents and camouflage clothing as combatants' clothing, not only need to have better camouflage function, but also should have wearing comfort, excellent light resistance and high Water pressure function. But the coloring material of current camouflage camouflage is mainly paint, and paint dyeing is generally used for the camouflage of fixed target, but it exists the problem of feel, rubbing fastness not good, and comfort is poor; In addition, existing camouflage fabric is parked in the open process , Sunlight is directly irradiated on the fabric, because the humidity can vary from 0 to 100%, and the combined effect of light (especially ultraviolet light), heat, and humidity will quickly destroy the dye on the fabric and c...
