Description
Technical field
The present invention relates to a kind of UV curable leather delustring treatment agent and preparation method thereof, belong to finishing field behind coating, natural leather, leatheroid, synthetic leather, the weaving face fabric.
Background technology
The delustring treatment agent is a kind of novel functional coating, after the coating of delustring treatment agent, can give natural leather, leatheroid, synthetic leather and the weaving face fabric feel of soft exquisiteness naturally, and along with the variation of coated weight can also provide vision benefits such as soft light sensation, haze change.Traditional leather flatting processing mainly comprises following several: 1, oil soluble delustring treatment agent, the normally physical mixture of ordinary resin and mute light powder; 2, water-based delustring treatment agent, the normally physical mixture of water-based PA, PU resin and mute light powder.Oil soluble delustring treatment agent is a class the most traditional the most ancient treatment agent, and the application time is long, the market occupancy is big, and resulting extinction effect is comparatively stable, but solvent usually accounts for more than 70% of delustring treatment agent in oil soluble delustring treatment agent; Water-based delustring treatment agent is the novel product that a class newly developed in recent years substitutes oil soluble delustring treatment agent, the water-based matting agent is solvent with water, comparatively environmental protection, but owing to the affinity difference of water to the mute light powder of difference, stability, the extinction effect of water-based delustring treatment agent are all poor than solvent-borne type usually.
Oil soluble delustring treatment agent contains a large amount of solvents, and in use, there is bigger pollution in the volatilization of solvent and is difficult to relatively environment reclaims; The comparatively environmental protection of water-based matting agent, but poor stability, effect does not usually reach the level that substitutes the oil soluble matting agent fully, and because the evaporation of water enthalpy is big, specific heat capacity is high, needs more power consumption under the use technology identical with oil soluble delustring treatment agent.
Summary of the invention
Technical problem to be solved by this invention provide a kind of technological design rationally, the UV curable leather delustring treatment agent of good, the constant product quality of energy-conserving and environment-protective, good stability, extinction effect.
