High-temperature-resistant synthetic leather slurry with high bonding strength and preparation method thereof

Abstract

The invention discloses high-temperature-resistant synthetic leather slurry with high bonding strength and a preparation method thereof. The high-temperature-resistant synthetic leather slurry is prepared from the following raw materials in parts by weight: 120-150 parts of polyurethane resin, 10-12 parts of zinc oxide, 3-4 parts of stearic acid, 2-4 parts of cellulose acetate, 1-2 parts of polypropylene, 2-3 parts of lauryl sodium sulfate, 1-3 parts of magnesium stearate, 4-6 parts of polyamide wax micropowder, 20-25 parts of soldering iron ore sands, 40-50 parts of barium sulfate packing, 12-15 parts of peanut leaves, 0.5-1.5 parts of monoethanolamine, 0.2-0.4 part of para aminobenzoic acid, 0.5-1.0 part of phosphotriester, 2-4 parts of glass wool, 6-7 parts of phenyl trichlorosilane and 65-80 parts of acetone. The slurry disclosed by the invention is simple in preparation process, low in cost and excellent in performance, has good viscidity, still can satisfy the viscidity requirement at high temperatures and has good wear resistance. By modifying the peanut leaves, the viscidity of the peanut leaves can be improved, the vicidity of the slurry is enhanced and the stable performance of the slurry is improved.

Description

Technical field [0001] The invention relates to a slurry for artificial leather, in particular to a high bonding strength and high temperature resistant synthetic leather slurry and a preparation method thereof. Background technique [0002] Polyurethane synthetic leather has excellent characteristics such as soft luster, naturalness, soft feel, strong leather feel, resistance to deflection, and anti-aging. It is the most ideal substitute for natural leather and is widely used in clothing, shoemaking, luggage, furniture and other industries ; But the polyurethane synthetic leather currently on the market is far from natural leather in terms of moisture permeability and abrasion resistance. Polyurethane synthetic leather products with poor moisture permeability will make people feel stuffy and humid. In view of these shortcomings, the current main change is to change the polyurethane The performance of the synthetic leather slurry is improved, but the process for changing the mois...

[0002] Polyurethane synthetic leather has the characteristics of soft and natural luster, soft hand feeling, strong leather feeling, flex resistance and anti-aging, etc. It is the most ideal substitute for natural leather and is widely used in clothing, shoemaking, bags, furniture and other industries However, the polyurethane synthetic leather on the market is far from 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 performance of synthetic leather slurry is improved, but the process of changing the moisture permeability and wear resistance of polyurethane synthetic leather slurry in the market is complicated, the cost is high, and the effect is not obvious
