Abstract
The utility model belongs to the technical field of man-made leathers and in particular relates to an aqueous polyurethane imitated leather. The imitated leather sequentially comprises an imitated cotton flannel base layer, an aqueous polyurethane connection layer, an aqueous polyurethane foaming layer and an aqueous surface processing layer. According to the aqueous polyurethane imitated leather, the imitated cotton flannel base layer and the aqueous polyurethane foaming layer are compounded through the aqueous polyurethane connection layer, and the aqueous surface processing layer is formed on the surface of the aqueous polyurethane foaming layer, so that the aqueous polyurethane foaming layer is protected, the imitated leather is glossy and the imitated effect is good; and an aqueous polyurethane material is an environmentally-friendly material, any plasticizer and organic solvent do not exist in production and use so as to avoid production workers and consumers from damaging, and the aqueous polyurethane material is environmentally-friendly, so that the product can pass various Euramerican environment protection quality system certifications and eliminate trade barriers.
Description
Technical field:
The utility model belongs to the dermatine technical field, refers in particular to a kind of aqueous polyurethane emulational leather.
Background technology:
Existing artificial simulated leather normally adopts PVC material or oiliness PU material to make, on its structure also just by PVC material layer or oiliness PU material layer more compound basic unit form.The shortcoming of existing leather is: adopting in the PVC manufacture of materials process has plasticiser to disengage, oiliness PU material then contains the DMF(dimethylformamide), plasticiser and DMF are to human body and the harmful material of environment, therefore not only not environmental protection also can bring threat to production work personnel and consumer's health.
The utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, and a kind of environment-friendly water-based polyurethane emulational leather is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of aqueous polyurethane emulational leather, this emulational leather comprise imitative napped cotton fabric basic unit, aqueous polyurethane following layer, aqueous polyurethane foaming layer and aqueous surface processing layer successively.
The thickness proportion of described imitative napped cotton fabric basic unit, aqueous polyurethane following layer, aqueous polyurethane foaming layer, aqueous surface processing layer is 8:2:5:1.
The utility model emulational leather by the aqueous polyurethane following layer compound imitative napped cotton fabric basic unit and aqueous polyurethane foaming layer, and at aqueous polyurethane foaming layer surface formation one deck aqueous surface processing layer, the aqueous polyurethane foaming layer is formed protection, emulational leather gloss is brighter, and simulated effect is better; And water-base polyurethane material is environment-friendly materials, all there are not plasticiser and organic solvent in production and the use, can avoid producers and consumer to be endangered, also friendly to environment, product can pass through American-European various environment-friendly quality system certifications, removal of barrier to trade.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
As shown in Figure 1, the utility model aqueous polyurethane emulational leather comprises imitative napped cotton fabric basic unit 1, aqueous polyurethane following layer 2, aqueous polyurethane foaming layer 3 and aqueous surface processing layer 4 successively.The thickness proportion of described imitative napped cotton fabric basic unit 1, aqueous polyurethane following layer 2, aqueous polyurethane foaming layer 3, aqueous surface processing layer 4 is 8:2:5:1.Its making step is as follows: at first be coated with on the release liners surface and scrape one deck water-base polyurethane material (its prescription is fit to as the polyurethane foam layer), form aqueous polyurethane foaming layer 3 through the oven dry back, (this layer water-base polyurethane material has viscosity to be coated with the water-base polyurethane material of scraping the another kind of prescription of one deck in aqueous polyurethane foaming layer 3 then, be fit to then), as aqueous polyurethane following layer 2, lay imitative napped cotton fabric basic unit 1 at aqueous polyurethane following layer 2 again, peel off release liners after drying processing again, the aqueous polyurethane foaming layer 3 surface attachment one deck aqueous surface processing layers 4 that expose after peelling off release liners then carry out printed pattern at last and handle the formation emulational leather.
The utlity model has following advantage:
1. with the supporting body of imitative velveteen base cloth as the water-based emulational leather, make product have the flexible characteristic that is fit to back processing;
2. the foaming layer of use Polyurethane is as the agent structure of water-based emulation skin leather, makes product have full feel as the corium, and its anti-performances such as elasticity, wrinkle recovery effects, resistance to impact of pulling out all significantly improve;
3. increase aqueous surface processing layer structure on aqueous polyurethane foaming layer surface, make product have good wear-resisting, anti-flexion and weatherability;
Between the supporting body of water-based emulation skin leather and the main body alveolar layer use Polyurethane following layer follow, compound, make product have good peel strength, satisfy access times, requirements such as intensity.
To sum up, the utility model emulational leather by the aqueous polyurethane following layer compound imitative napped cotton fabric basic unit and aqueous polyurethane embossing alveolar layer, and at aqueous polyurethane embossing alveolar layer surface formation one deck aqueous surface processing layer, aqueous polyurethane embossing alveolar layer is formed protection, emulational leather gloss is brighter, and simulated effect is better; And water-base polyurethane material is environment-friendly materials, all there are not plasticiser and organic solvent in production and the use, can avoid producers and consumer to be endangered, also friendly to environment, product can pass through American-European various environment-friendly quality system certifications, removal of barrier to trade.
