| titleOfInvention | Water-repellent canvas and preparation method thereof |
| abstract | The invention relates to a water-repellent canvas and a preparation method thereof, wherein the preparation method comprises the following steps: padding the modified polyester industrial yarn woven fabric with a waterproof finishing agent, and coating a waterproof coating on the surface of the modified polyester industrial yarn woven fabric to prepare water-repellent canvas; the modified polyester industrial yarn is prepared by solid phase polycondensation tackifying, melting, metering, extruding, cooling, oiling, stretching, heat setting and winding of modified polyester melt; the preparation method of the modified polyester before solid phase polycondensation tackifying comprises the following steps: terephthalic acid, ethylene glycol, dihydric alcohol with tertiary butyl side group and doping modified Sb 2 O 3 And after the powder is uniformly mixed, carrying out esterification reaction and polycondensation reaction in sequence. The peel strength of the prepared product is more than or equal to 10N/cm, the use temperature range is-30 ℃ to +60 ℃, the hydrostatic pressure resistance value is more than or equal to 100KPa, and the friction resistance value is more than or equal to 3000. The preparation method has simple process, reduces the addition of the antimony catalyst and has low cost; the prepared product has high peel strength and good application prospect. |
