Description
Technical Field
The invention relates to the field of synthetic leather, in particular to an ecological finishing agent for synthetic leather.
Background
The water-based visible light driven film-forming coating agent for the ecological synthetic leather is a coating agent required by the ecological synthetic leather, can endow the production of the synthetic leather with energy conservation and environmental protection, and can endow the synthetic leather with certain hand feeling. The conventional synthetic leather finishing agent is mostly prepared by adopting solvent type polyurethane resin, diluting the solvent and adding various auxiliary agents, and when the coating agent is used, the coating agent is coated on the surface of the synthetic leather and then heated to volatilize the solvent, so that a polyurethane finishing layer is formed on the surface of the synthetic leather. The existing synthetic leather finishing agent has the following defects: 1. because the solvent type polyurethane usually adopts an organic solvent, the solvent can volatilize to cause pollution in the using process, and the current requirement on environmental protection is not met. The water-based polyurethane leather treating agent adopts water-based polyurethane as a main carrier, does not use or only uses a little amount of low-toxicity organic solvent, does not cause pollution to the environment, and meets the current requirement on environmental protection. 2. The molecular weight and viscosity of the solvent type polyurethane resin have a corresponding relationship, and the viscosity of the solvent type polyurethane resin is low due to the low molecular weight. In the preparation of leather finishes requiring high gloss, polyurethane resins with high solids content and low viscosity are generally selected, which, due to their low molecular weight, are affected in terms of physical properties as well as resistance to heat, release and weathering. The aqueous polyurethane is in an emulsion state, and the viscosity and the molecular weight are not necessarily related, so that when the high-solid low-viscosity high-gloss leather finishing agent is prepared, the polyurethane resin keeps higher molecular weight, and the physical properties and other application properties of the polyurethane resin are not influenced at all. 3. The film forming mechanism of the solvent type polyurethane coating is different from that of the water-based polyurethane coating, and the solvent type polyurethane coating forms a uniform polyurethane film which has strong plastic feeling and is not natural enough when the glossiness is higher. The water-based polyurethane leather finishing agent is emulsion, and the film forming is formed by stacking emulsion particle sizes and has similar points with the unevenness formed by fiber structures of genuine leather, so that the gloss and the hand feeling after the film forming are more natural and are closer to the genuine leather.
Disclosure of Invention
Aiming at the defects of the coating agent for the synthetic leather, the invention aims to provide the water-based visible light driven film forming coating agent for the ecological synthetic leather. The finishing agent can be used on the surface of solvent type synthetic leather and the surface of water-based synthetic leather, solves the problem of poor anti-sticking performance of water-based polyurethane resin, and has better glossiness, anti-sticking performance and low-temperature storage stability than the existing solvent type polyurethane leather finishing agent. In addition, the prepared coating agent also has the functions of degrading organic waste gas, self-driving by visible light, saving energy, reducing consumption and protecting environment.
In order to achieve the purpose, the invention adopts the following preparation technical scheme:
firstly, adipic acid and oligomeric tetrahydrofuran diol are mixed according to a molar ratio of 1-1.5: 1.5-2 ℃, 80-90 ℃, and reacting for 4 hours under the condition of water bath reduced pressure distillation and dehydration by using concentrated sulfuric acid as a catalyst to prepare polyester-polyether glycol;
secondly, calcining the urea for 2-5 h in a nitrogen atmosphere at 500-700 ℃, cooling, and then continuously calcining for 2-5 h in an air atmosphere at 500-700 ℃ for later use;
then, polyester-polyether diol is used as a soft segment, micromolecular diol is used as a chain extender, hydroxyethyl acrylate is used as a terminal capping agent, IPDI is used as a hard segment, and the molar ratio of the polyester-polyether diol to the small molecular diol is 1-1.5: 0.1-0.3: 0.5-1: 1-1.5, reacting for 3-6 h at 75-85 ℃ with dibutyltin dilaurate as a catalyst (0.1-0.3 wt%);
and finally, performing reaction by using a photoinitiator BASF184/Irgacure261 according to the weight ratio of 1-5: 1-1.5 mol ratio to obtain the water-based visible light driven film-forming finishing agent for the ecological synthetic leather. Tests show that the water-based visible light driven film-forming finishing agent for ecological synthetic leather reaches or exceeds the solvent type polyurethane leather finishing agent in the aspects of gloss, transparency, physical strength and the like, and can completely replace the existing solvent type polyurethane leather finishing agent. In addition, the prepared coating agent can realize visible light self-driven film forming and curing and can degrade organic waste gas.
Detailed Description
First, adipic acid and an oligomeric tetrahydrofuran diol were mixed in a molar ratio of 1: reacting for 4 hours at 1.5 and 85 ℃ under the condition of taking concentrated sulfuric acid as a catalyst and carrying out water bath reduced pressure distillation dehydration to prepare polyester-polyether glycol;
secondly, calcining the urea for 3 hours at 550 ℃ in a nitrogen atmosphere, cooling, and then continuously calcining for 3 hours at 550 ℃ in an air atmosphere for later use; then, polyester-polyether diol is used as a soft segment, micromolecular diol is used as a chain extender, hydroxyethyl acrylate is used as a terminal capping agent, IPDI is used as a hard segment, and the molar ratio of the polyether diol to the polyester-polyether diol is 1: 0.1: 0.5: 1, reacting for 3 hours at 80 ℃ with dibutyltin dilaurate as a catalyst (0.1 wt percent); finally, the ratio by photoinitiator BASF184/Irgacure261 was 1: 1 mol ratio, and uniformly stirring according to the total addition of 0.5 wt% and 23 wt% of water, 65wt% of prepared pre-polymerized urethane acrylate and 11.5 wt% of diluent TPGDA to obtain the water-based visible light driven film-forming finishing agent for ecological synthetic leather. The coating agent can form a film after 5min under a 60W incandescent lamp, and has better capability of degrading the organic pollutant model RhB.
