Abstract

The invention relates to an environment-friendly water-based spinning coating adhesive and a preparation method thereof, belonging to the technical field of textile coating materials. The coating adhesive is mainly prepared from major ingredients, auxiliary agents and water, wherein the major ingredients comprise butyl acrylate, ethyl acrylate, crylic acid, hydroxy-ethyl acrylate or oxypropyl acrylate, TDI and MDI, and the auxiliary agents comprise mulsifier, itaconic acid, evocating agent, cross linker and sealant. The textile coating material is an environment-friendly and high-grade spinning coating adhesive with the product quality reaching to the national advanced level and the cost being only 70 percent of import products. The preparation method and the using process are environment-friendly and can greatly reduce environmental pollution caused by spinning industrial production.

Description

(1) Technical field [0001] The invention belongs to the technical field of fabric coating materials, and in particular relates to an environment-friendly water-based coating glue and a preparation method thereof. (2) Background technology [0002] Fabric coating is the compounding of fabric and high molecular polymer. After compounding, the performance of textiles changes significantly. It not only retains the original function of the fabric, but also increases the function of the covering layer. Fabric coating technology creates functional properties for the textile industry. Fabrics provide more possibilities, greatly broaden the use of textiles, and the application fields are becoming wider and wider. 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....
