Abstract

The invention discloses environment-friendly type PVC (polyvinyl chloride) synthetic leather. The environment-friendly type PVC synthetic leather is prepared from the following raw materials in parts by weight: 30-60 parts of polyvinyl chloride resin SG-5 (PVCSG-5), 15-30 parts of polyvinyl chloride resin SG-8 (PVCSG-8), 10-15 parts of egg shell powder, 3-6 parts of rice bran, 2-5 parts of rice husk, 2-4 parts of wollastonite powder, 0.2-0.5 part of aluminum oxide, 40-70 parts of trioctyl citrate, 15-30 parts of trimethyl citrate, 1-2 parts of isopropanolamine, 0.5-1 parts of lactose, 0.2-0.5 part of calcium chloride, 0.5-1.5 parts of dioctyl sodium sulfosuccinate, 1-2 parts of turkey red oil, 0.5-1 part of polyamide epichlorohydrin, 5-10 parts of pigment and 5-10 parts of modifying additives. The PVC synthetic leather uses agricultural wastes as filling materials, is environmentally-friendly, can improve the air permeability and toughness and is suitable for practical production use, and energy can be saved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an environment-friendly PVC synthetic leather and a production method thereof. Background technique [0002] At present, synthetic leather is mainly divided into two types: polyvinyl chloride (PVC) synthetic leather and polyurethane (PU) synthetic leather. PU synthetic leather has good hand feel and appearance quality, but the price is high and the service life is not long, and the current mature PU synthetic leather process requires a large amount of DMF as a solvent, and the environmental effect is not good; PVC synthetic leather is low in price and its physical properties can reach Quality requirements, the disadvantage is that the quality of the feel and appearance is slightly poor, and the air permeability is poor, which limits its wider use. Rational use of industrial and agricultural waste, and improvement of formula and process, not only help to improve the performance o...
