Problems solved by technology

[0004] However, the light stability and thermal stability of the current fabric coating slurry are poor, especially the polyurethane solid content used is very low, the particle size is large and uneven, and the contact angle of the adhesive film is small, and the hydrophobicity is low. Very poor, resulting in poor oil resistance and water resistance of the overall coating, which needs further improvement

Abstract

The invention discloses fabric coating slurry which is prepared by the following components, by weight, of 100 parts of epoxidized soybean oil modified waterborne polyurethane, 5-10 parts of crosslink type macromolecule emulsion thickening agents BJ-100 and 5-10 parts of fabric coating extrusion dispersing agents PTFE D-210. The invention discloses a preparing method of the fabric coating slurry at the same time. The fabric coating slurry is well improved in light stability, heat stability, oil resistance and water resistance.

Description

technical field [0001] The invention relates to an environment-friendly fabric coating slurry, in particular to a fabric coating slurry prepared by using epoxy soybean oil modified water-based polyurethane, and to a preparation method of the fabric coating slurry. Background technique [0002] At present, in the textile industry, polyurethane has shown good performance in printing and dyeing auxiliaries and finishing agents. Fabric coating finishing is to coat a thin film on the surface of textiles, so that the fabrics have certain special functions (such as anti-wrinkle, light-shielding, water-repellent, oil-proof, flame-retardant, warm, imitation down, reflective, breathable, etc.) ) or appearance style. Because water-based polyurethane does not contain organic solvents such as formaldehyde, it has become the development direction of fabric dyeing and finishing as a formaldehyde-free fabric finishing agent. As a leather finishing agent and fabric coating glue, water-base...
