Problems solved by technology

The finishing agent better solves the problems of solvent recovery, safety and environmental protection, which used volatile organic solvents in the production process of the previous UV-curable leather finishing agents.
At the same time, it also solves the storage stability problem (gel phenomenon) of solvent-free UV-curable leather finishing agent to a certain extent. It can be stored for up to one year, but it still cannot meet the requirements of high-speed production development for long-distance transportation and storage.

Abstract

The invention relates to a nanometer modified ultraviolet curing coating for synthetic leather and a preparation method thereof. The coating comprises the following components in percentage by mass: 35 to 50 percent of acrylic ester oligomers, 45 to 60 percent of acrylic ester active monomers, 3.5 to 8.0 percent of photoinitiator and co-initiator, 0.5 to 1.5 percent of flattening agent, 0.5 to 1.0 percent of defoaming agent, 0.5 to 1.5 percent of wetting dispersant, 0.5 to 1.0 percent of polymerization retarder, 1.0 to 1.5 percent of nanometer material, and 8.0 to 12.0 percent of dye solution. The nanometer modified ultraviolet curing coating for the synthetic leather adopts more reasonable components and does not use organic solvent, so the problem of the volatilization of the organic solvent does not exist during the production, and the storage stability can also be improved to more than 18 months at the same time.

Description

technical field [0001] The invention belongs to ultraviolet light curing coatings in the field of chemical industry, in particular to a nano-modified ultraviolet light curing coating for synthetic leather. Background technique [0002] Applying photocuring technology to the surface treatment of synthetic leather (leather) has outstanding advantages: First, the curing speed of the coating film is fast, and the liquid UV coating can complete the crosslinking reaction within a few seconds. Compared with the thermal curing process of PU coatings, it greatly improves Productivity. Second, the product quality is good, which improves the market competitiveness of high-grade mirror-finished synthetic leather. The third is to save energy, reduce the comprehensive cost of production, reduce the electric energy by 50%, shorten the length of the production line by 2 to 4 times, occupy less land, and save investment. However, due to the use of volatile organic solvents in the productio...
