Polyvinyl chloride (PVC) synthetic leather and production method thereof for bags and suitcases

Abstract

The invention discloses polyvinyl chloride (PVC) synthetic leather for bags and suitcases. The PVC synthetic leather comprises, by weight, 30-60 parts of PVCSG-5, 15-30 parts of PVCSG-8, 30-60 parts of di-n-octyl phthalate, 15-30 parts of trihexyl citrate, 1-2 parts of isooctyl palmitate, 2-6 parts of moxa, 5-10 parts of pyrophillite, 2-5 parts of seaweed gel, 4-8 parts of kaoline, 4-8 parts of blanc fixe, 2-6 parts of rush powder, 0.5-1.5 parts of soybean protein fibers, 1-3 parts of maltitol, 0.5-1 part of sodium alginate, 1-2 parts of sodium thiosulfate, 5-10 parts of pigments and 5-10 parts of performance additives. According to the PVC synthetic leather for the bags and the suitcases, growing and breeding of microorganisms can be effectively inhibited, the sanitation property is good, the PVC synthetic leather is physically beneficial, the mechanical property is high, hand feel and comfort degree are good, and the PVC synthetic leather is suitable for the bags and the suitcases.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PVC synthetic leather for bags 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. Contents of the invention [0003] The purpose of the present invention is to provide a kind of PVC synthetic leather for bags. [0004] The pr...
