Description

V. Description of the invention (1) [Field of invention] The present invention is a surface treatment composition [Background of the invention] The demand for leather appliances, clothing, and leather is expensive and expensive, because of the kind of leather made of aerated vinyl). This has to be done again. The current industry resin, which is solidified into a dry artificial leather cloth many times, is not only good. In addition, when organic solvent products are used, they will be threatened, which will lead to environmental protection in all parts of the field. Therefore, countries around the world need to consume economically when operating with low pollution. UV (ultraviolet) hardening mist 4254 彳 6 for these artificial leathers is widely used and can be used for a variety of decorative purposes. But it has also increased relatively. However, this artificial leather has emerged at the historic moment. For example, the properties of PU (polyurethane vinegar leather, PVC flocking leather, and PVC dairy leather) and the surface treatment of natural leather, while the surface-used artificial leather has a lot of content. Below 20%, the major resin companies are to strengthen the major resin companies such as three-dimensional sense, high consumption of man-hours, and environmental pollution caused by the use of environmental pollution-type resins in downstream industries, which are difficult to find for operators and operators. Both of them are oriented towards low-sewage resins. However, under the condition that water costs more energy and dries the moisture, UV curing has been developed, such as using leather to replace leather, synthetic leather, etc. Leather treatment agents are mostly agents that are therefore intended to produce handfeel effects, and are effective in producing energy for the two workers. Further prevention and control regulations Dyeing direction research Resin pollution ’In industrial resins, there are more leather bags and households, which have limited sources and leather. People's PVC (there are differences due to demand. Organic solvent-based high-coated dry products often have to be coated with fruit and often not twice or three times plus health and other powerful people. Low, but this resin is not used by

Description of the invention (2) The diluent solvents are all reactive solvents, so it is not only pollution-free, but requires only a small amount of energy to achieve curing, and the reaction speed is fast. Increase production and decrease: production cost, and UV curing reaction more than 4 crosslinking ㈤, so physical properties such as resistance, solvent resistance are better than solvent-based resins. However, currently developed UV-curable resins are roughly divided into soft and hard. Soft UV-curable resins are mostly used for glazing on paper, and the thickness of the coating film is less than 20 Θ. It is not suitable for thick coating, and the requirements of resistance and bending resistance cannot meet the requirements of artificial leather. The “hard” hardening resin is mostly used in wood coating and can coating. Although its scratch resistance is better but its softness is not enough: ¾ The coating used for artificial leather is stiff and has poor adhesion and flex. Disadvantages such as poor performance, poor feel, inapplicability, and no sense of value, so there is currently no ideal UV-curable resin for the artificial leather industry. The present inventors have conducted extensive research based on the above-mentioned problems, and thus completed the present invention. [Summary of the Invention] The present invention provides a UV-curable matte treatment composition for artificial leather, which includes 95 to 40% by weight of a polyurethane polymer, 5 to 60% by weight of an acrylic monomer, and the polyamine is 1 to 15% by weight of the total weight of the urethane polymer and the acrylic monomer, and 1 to 30% by weight of the total weight of the polyurethane polymer and the acrylic monomer. 1 to 15% by weight of co-initiator based on the total weight of the polyurethane oligomer and the acrylic monomer.
