Abstract

The invention discloses PVC synthetic leather containing green tea extracts. The PVC synthetic leather is prepared from, by weight, 30-60 parts of PVC SG-5, 15-30 parts of PVC SG-8, 50-80 parts of diethyl phthalate, 2-4 parts of triethyl citrate, 0.1-0.5 part of ethyl p-hydroxybenzoate, 5-10 parts of fluorite ore powder, 10-15 parts of vermiculite powder, 5-10 parts of tea oil seedcake meal, 2-4 parts of glycerin, 1-3 parts of sodium stearate, 1-2 parts of xanthan gum, 0.5-1 part of flaxseed gum, 1-2 parts of green tea extracts, 0.2-1 part of polyoxyethylene isooctyl ether phosphate, 0.5-1 part of lauryl sodium sulfate, 5-10 parts of pigment and 5-10 parts of modification additives. The PVC synthetic leather can effectively prevent bacteria, has the anti-oxidation and anti-corrosion effect, can effectively improve the phenomenon that products become yellow and go bad, is good in physical performance, accords with industrial standard requirements and is wide in application range.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PVC synthetic leather containing green tea extract 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 PVC synthetic leather with good perf...
