Description
Technical field
The utility model is related to a kind of solvent-free environment-protection compound polyurethane material.
Background technology
Synthetic leather is organization and the serviceability of simulation natural leather, and can be compound as natural leather substitute
Material.Generally lamina reticularis is simulated with non-woven fabrics, with microvoid polyurethane coating simulation grain layer, obtained synthetic leather positive and negative
All quite similar with leather, and there is certain gas permeability, than common artificial leather closer to the hot leather in sky, it is widely used in making
Footwear, boots, case and bag and ball etc..
2013, China's synthetic leather developing state was good, and synthetic leather yield has reached 180.45 ten thousand tons, synthetic leather market
43,500,000,000 yuan of scale.2013 are so far, and the synthetic leather consumption figure of China increases to 42.92 hundred million square metres from 16.12 hundred million square metres,
Average compound growth rate is about 13.02%.With the raising of people's living standard, the requirement to product for the terminal use is increasingly
Height, mid- to high-end product will progressively replace low-end product, and consumption upgrading drives the high-end synthetic leather market demand to increase.Meanwhile,
Environmental protection policy is increasingly tightened up, and the synthetic leather production capacity falling behind will progressively be eliminated, and middle and high end synthetic leather substitutes low-end product to be become
Trend of the times.
Traditional synthetic leather is mainly solvent type synthetic leather, and its technological process is as follows：Non-weaving cloth → coating solvent type gathers
Urethane wet coagulation coating (bottom) → washing → drying → solvent borne polyurethane dry method transfer coated (upper strata), it is not only being given birth to
Produce in link and there is Heavy environmental pollution, and also remain pollutant in the synthetic leather product being obtained, main performance is as follows：
First, using solvent borne polyurethane wet coagulation coating as bottom, wet coagulation coating is to starch solvent borne polyurethane (PU)
Material, is coated on the surface of non-weaving cloth using coating roller, subsequently into DMF aqueous coagulation bath, so that PU is solidified and be formed and have
The film of microcellular structure.It can be seen that, employ DMF (dimethylformamide) in this technical process and make solvent, process can cause
The solvent contamination of DMF, and in process of setting, water can not replace the DMF in polyurethane completely, and the DMF of product can be caused residual
Stay problem, will ultimately result in Product quality and safety problem.Second, membrane coat is moved as top layer using solvent borne polyurethane dry method,
It is by solvent borne polyurethane slurry, is coated on the surface of release liners using doctor knife coater, then shift gel coating with wet method
Non-weaving cloth laminating, be dried after peel off, by polyurethane film transfer to wet method move film layer surface, finally give synthetic leather.By
Solvent-borne type decorative system is employed in the preparation of this top layer, containing substantial amounts of toxic organic solvents, such as TOL (toluene), MEK
(MEK) and DMF (dimethylformamide) etc., and these organic solvents and its volatilization, serious environment pollution to live behaviour
Make the healthy of personnel to threaten.
In order to improve problem of environmental pollution present in traditional solvent-borne production technology, people start to put forth effort on environment-friendly type and gather
The research and development of urethane synthetic leather, current most study is waterborne polyurethane synthetic leather and no-solvent type Synthetic Leather.Aqueous
Although Synthetic Leather can solve the problem that the volatile solvent pollution problem in solvent borne polyurethane production technology and aqueous poly-
The outward appearance of urethane synthetic leather is closer to natural leather, and the sanitation performance of coating is more preferable.But the thing of waterborne polyurethane synthetic leather
Reason mechanical performance more larger than the physical and mechanical properties gap of solvent borne polyurethane synthetic leather it is difficult to meet the application need of actual product
Ask, meanwhile, the production efficiency of waterborne polyurethane synthetic leather is relatively low, lead to the business efficiency of factory poor, and aqueous polyurethane
Price is higher, and product cost is also high, reduces enterprise profit space further.Uninanned platform is removed from office for production technology, undoubtedly
Become one of main development direction of following synthetic leather, although current uninanned platform leather production technology employ solvent-free
Dual-component polyurethane formed foaming layer, but its surface layer still using aqueous PU or oiliness PU it is impossible to accomplish completely solvent-free, still
There is the defects such as environmental pollution, price be higher.
