Abstract

The invention provides an additive for polyurethane synthetic leather and a preparation method thereof. The additive is prepared from the following raw materials by weight: 25-28 parts of polyester resin, 7-9 parts of terpene resin, 2-3 parts of white carbon black, 1.2-1.5 parts of soap powder, 1.8-2.2 parts of ethylene-bis-stearamide, 0.8-1.3 parts of a silane coupling agent, 0.6-0.7 part of betaine, 1.2 parts of a dispersant, 0.6 part of a fluorine drying agent, and 60-65 parts of water. The additive provided by the invention can be added into synthetic leather to use, is harmless to the environment, also has no harm to human health, and can improve the water resistance and stability of synthetic leather. The finally obtained synthetic leather has the characteristics of antistatic properties, low irritation, sterilization, low toxicity, emulsification dispersion, chemical stability and biodegradability, etc.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to an additive for polyurethane synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. [0003] Synthetic leather is used to make shoes, boots, bags and balls, and is also widely used in upholstery, mattresses, sofas and cars as a substitute for real leather, but the current synthetic leather is prone to the following problems: In some applications The internal functions are not perfect, the comfort and practicabilit...
