Problems solved by technology

[0002] Industrially produced PVC artificial leather has a large polydispersity, and its molecular weight increases with the decrease of polymerization temperature. After years of development, PVC artificial leather is widely used in my country, including building materials, sealing materials, fibers, etc. The proportion of PVC materials used in luggage and children's toys is also increasing. However, due to the poor degradation of traditional PVC materials, the disposal of waste PVC materials has become a big problem, and the water resistance of PVC materials is not high, which greatly shortens the Lifespan of PVC artificial leather

Abstract

The invention discloses novel environment-friendly degradable PVC artificial leather and a production process thereof. The novel environment-friendly degradable PVC artificial leather comprises hydroxamated polyvinyl chloride, modified talcum powder, decayed apples, citric acid, xanthan gum, copper chloride, a fabric substrate, synthetic resin, a plasticizer, a coupling agent and an anti-wrinkle agent. The hydroxamated polyvinyl chloride contains carbonyl and oximido at the same time, so that the phase compatibility between the components is improved; small molecular carbon compounds formed during degradation can attract bacillus subtilis, so that the degradation of the hydroxamated polyvinyl chloride is promoted; the talcum powder can improve the water contact tolerance of the resin; the citric acid modified talcum powder improves the toughness and tensile strength of the synthetic resin; phytosterol and the citric acid generate phytosterol ester as an artificial leather skin film, and the synthetic artificial leather has waterproof and oilproof effects due to good hydrophobicity and oleophobicity of the phytosterol ester; and the manufacturing process for preparing the artificial leather from the abandoned apples saves resources, protects the environment and increases the additional output value of the abandoned apples.

Description

technical field [0001] The invention relates to the technical field of PVC artificial leather, in particular to a novel environment-friendly and degradable PVC artificial leather and a production process thereof. Background technique [0002] Industrially produced PVC artificial leather has a large polydispersity, and its molecular weight increases with the decrease of polymerization temperature. After years of development, PVC artificial leather is widely used in my country, including building materials, sealing materials, fibers, etc. The proportion of PVC materials used in luggage and children's toys is also increasing. However, due to the poor degradation of traditional PVC materials, the disposal of waste PVC materials has become a big problem, and the water resistance of PVC materials is not high, which greatly shortens the Lifespan of PVC artificial leather. Therefore, it is necessary to design a new environmentally friendly degradable PVC artificial leather that is de...
