Problems solved by technology

Only a small amount of these discarded feathers are made into pillows, quilts, feather fans, badmintons, etc. Most of them are discarded as garbage, which not only causes environmental pollution, but also causes harm to human health.
Moreover, the main component of discarded feathers is keratin, which is not easy to degrade itself in the soil, and cannot be used directly as an organic fertilizer.

Abstract

The invention discloses a preparation method of flame-retardant, anti-abrasion and leather-feeling simulation synthetic leather paste. The preparation method includes: mixing 80g of polytetrahydrofuran glycol with 45g of methylene diphenyl diisocyanate and allowing polyurethane prepolymer to occur in the reaction of 2 hours under 85DEG C in the presence of 0.12g of a catalyst; adding 4-amino-5-hydroxy-2, 3.5g of 7-naphthalene disulfonic acid, 3.5g of mannitol and 3.2g of N-hydroxymethyl acrylamide, dropwise adding 5.3g of 10% of an initiator aqueous solution and 6.6g of a chicken feather solution simultaneously at 80DEG C for 1 hour, performing thermal reaction for 2 hours after dropwise adding and adjusting pH value to be 7.5 after completion of reaction to obtain flame-retardant thermoplastic polyurethane; proportionally and evenly stirring 60 parts of the flame-retardant thermoplastic polyurethane, 15 parts of butanone, an HDI tripolymer curing agent and a bismuth quantitative catalyst to prepare the colorless and high-transparent paste. The synthetic leather paste is good in flame-retardant, anti-abrasion and leather-feeling simulation properties.

Description

technical field [0001] The invention relates to a method for preparing synthetic leather, in particular to a method for preparing synthetic leather slurry with flame retardancy, wear resistance and artificial leather feeling. Background technique [0002] Polyurethane synthetic leather has the characteristics of soft and natural luster, soft hand feeling, strong leather feeling, resistance to warping, anti-aging, etc. It is the most ideal substitute for natural leather and is widely used in clothing, shoemaking, bags, furniture and other industries , but the polyurethane synthetic leather currently on the market is far behind natural leather in terms of moisture permeability and wear resistance. Polyurethane synthetic leather products with poor moisture permeability will make people feel stuffy and cold. The properties of synthetic leather sizing are improved, but the process of changing the moisture permeability and wear resistance of polyurethane synthetic leather sizing i...
