The composition allows for a well-balanced combination of a good impact / stiffness balance, a good scratch resistance, low VOC and FOG emissions and remarkable good fogging values.

The invention discloses a manufacturing technology for flame-retardant, light-resistant, low-fogging and degradable cowhide car seat cushion leather. According to the manufacturing technology, ammonium salt deliming is replaced by ammonium-salt-free deliming, tetrakis hydroxymethyl phosphonium sulphate and a flame-retardant starch-type leather surfactant are selected as a leather tanning agent to replace a traditional chrome tanning agent, the fogging value of the seat cushion leather is reduced through high-temperature washing, the flame-retardant property of the leather is improved through retanning, fat liquoring and coating step by step, the light resistance of a coating is improved through a light-resistant material, and the usage quantity of leather chemicals is decreased by selecting roll coating to replace spray coating.

The invention relates to a preparation method of a jatropha carcass oil base polymer fatting agent. The preparation method comprises the following steps: a, performing epoxidation on jatropha carcassoil by using hydrogen peroxide, glacial acetic acid and concentrated sulfuric acid so as to obtain epoxy jatropha carcass oil; b, by taking sodium p-toluenesulfonate as a catalyst, hydroquinone as a polymerization inhibitor, and acrylic acid as a nucleophilic reagent, performing a ring-opening reaction on the epoxy jatropha carcass oil so as to obtain acrylic acid esterified jatropha carcass oil,and introducing an active vinyl part to a plant oil molecular chain; and c, by taking 2,2'-azobis(2-methylpropionitrile) as a catalyst, and acetanilide as an anti-gel agent, adding maleic anhydride, acrylic acid and acrylic acid esterified jatropha carcass oil, and performing copolymerization, thereby obtaining the jatropha carcass oil base polymer fatting agent. Based on natural plant oil which is cheap and easily available as a raw material, the prepared polymer fatting agent is relatively good in cold water emulsification property and good in hydrophilcity, and is an environment-friendly and degradable fatting material.

The invention provides a low-atomization leather synthetic fatliquoring agent as well as its preparation method and application, and relates to the technical field of leather chemical industry. The synthetic fatliquoring agent for low atomization leather provided by the present invention, the preparation raw material comprises the following components by weight: 20-40 parts of N-oleoyl sarcosine; 50-100 parts of palm oil; 10-20 parts of maleic anhydride 10-50 parts of high boiling point mineral oil; 10-50 parts of synthetic oil; 5-50 parts of neutralizer; 10-30 parts of emulsifier; 100-200 parts of water. In the raw material components used in the present invention, there are less unsaturated oils and volatile components, and the higher saturation of palm oil is used to further reduce the formation of volatiles through chemical modification, and then matched with high-boiling point mineral oil, thereby reducing fog value and VOC; the low fogging leather synthetic fatliquoring agent provided by the invention is used for automobile upholstery leather, and good low fogging performance can be obtained.
