A kind of high-solid low-viscosity mirror synthetic leather treatment agent and preparation method thereof

Abstract

The invention discloses a high-solid low-viscosity mirror synthetic leather treatment agent and a preparation method thereof. The high-solid low-viscosity mirror synthetic leather treatment agent comprises a main agent and a curing agent, wherein the main agent adopts 3-isocyanate methylene-3,5,5-trimethylcyclohexyl isocyanate, 3-isocyanatopropyltrimethoxysilane and (1S,2S)-(+)-2-benzyl cyclohexylisocyanate as a mixed base material, adopts dibutyltin dilaurate as a catalyst, adopts a mixture of dimethyl carbonate and vinyl acetate as a solvent, and also comprises polyether polyol and micromolecular polyols. The curing agent comprises a flatting agent, a foaming agent, tetrabutyl titanate, butyl butyrate and dibutylester nylon acids. The main agent and the curing agent are uniformly mixedto obtain the high-solid low-viscosity mirror synthetic leather treatment agent disclosed by the invention. The solid content of the synthetic leather treatment agent reaches 80 percent at most. The synthetic leather treatment agent is relatively low in initial viscosity, thereby facilitating the manual operation, and improving the utilization rate of the treatment agent; and after a period of time, the viscosity is greatly improved, so that the actual production and life requirement can be met.

Description

technical field [0001] The invention relates to the technical field of synthetic leather surface finishing, and more specifically relates to a high-solid and low-viscosity mirror surface synthetic leather treatment agent 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. The front and back of synthetic leather are very similar to leather, and it has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. [0003] With the rapid development of society, consumers have higher and higher demands on the brightness and feel of synthetic leather; manufacturers often use various synth...

AI Technical Summary

Problems solved by technology

The common synthetic leather treatment agent is actually a kind of polyurethane resin; if the initial viscosity of the existing synthetic leather treatment agent is low, its final viscosity will not be very high, which makes its bonding strength weak and cannot really meet the needs of actual production and life. Therefore, the initial viscosity of the synthetic leather treatment agent in real life is high; but this is easy to cause the synthetic leather treatment agent to stick to the workers or the surrounding objects, resulting in a large amount of synthetic leather treatment agent that cannot be really used, and the waste is serious ; At the same time, it also increases the difficulty of handling synthetic leather
