Abstract
The present invention discloses a wear-resistant polyurethane film, which comprises the following chemical components by mass: 50-60 parts of polyurethane, 8-14 parts of stearic acid, 2-6 parts of a coupling agent, 3-5 parts of graphite powder, 12-18 parts of toluene diisocyanate, 16-22 parts of a tackifier, and 10-20 parts of a wear-resistance aid, wherein the wear-resistance aid is prepared by mixing 24-28% by mass of sodium lignin sulfonate and 72-76% of polytetrafluoroethylene. According to the present invention, the wear-resistant polyurethane film has advantages of high strength, wear resistance, strong adhesion, and substantially-improved use value.
Description
Technical field
The present invention relates to a kind of macromolecular material, particularly a kind of wear-resistant type polyurethane film.
Background technology
Along with the adjustment of expanding economy and the structure of rural undertaking, the market requirement of China's all trades and professions to plastics film constantly rises, wherein, polyurethane film because of its superior performance and environmental protection concept day by day welcomed by the people, polyurethane film not only can with various cloth pasting, clear-cut can also be produced by the method for vacuum thermoforming, the product of dimensional stabilizing, then in the process used, film is all plated on product surface, therefore the wear resistance for film requires very harsh, and traditional film is more difficult meets its requirement.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of wear-resistant type polyurethane film, can have the advantage of high strength, wear-resisting, strong adhesion, significantly improve use value.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of wear-resistant type polyurethane film, the mass fraction of its chemical composition is specific as follows:
Urethane 50-60 part, stearic acid 8-14 part, coupling agent 2-6 part, Graphite Powder 99 3-5 part, tolylene diisocyanate 12-18 part, tackifier 16-22 part, antiwear assistant 10-20 part;
Described antiwear assistant is mixed by sodium lignosulfonate and tetrafluoroethylene, and calculate according to mass percent, the content of described sodium lignosulfonate accounts for 24-28%, and the content of described tetrafluoroethylene accounts for 72-76%.
In a preferred embodiment of the present invention, described coupling agent is aminopropyl triethoxysilane.
In a preferred embodiment of the present invention, described tackifier are aliphatic hydrocarbon resin.
In a preferred embodiment of the present invention, in described antiwear assistant, the concrete proportioning of composition is: the content of described sodium lignosulfonate accounts for 26%, and the content of described tetrafluoroethylene accounts for 74%.
The invention has the beneficial effects as follows: the present invention can have the advantage of high strength, wear-resisting, strong adhesion, significantly improves use value.
