Abstract
The invention discloses a high-strength polyurethane film which comprises a polyurethane coating located on the uppermost layer, a bonding agent located in the middle and an inorganic fiber layer located on the lowermost layer. The polyurethane coating is formed by, by mass, 66%-72% of diisocyanate and 28%-34% of dihydroxy acetone through addition polymerization, and the inorganic fiber layer is prepared by mixing, by mass, 55%-65% of glass fibers and 35%-45% of ceramic fibers. In this way, the high-strength polyurethane film has the advantages of being high in strength and ductility and resistant to wear, and the use value is improved.
Description
Technical field
The present invention relates to a kind of macromolecular material, particularly a kind of high-strength polyurethane film.
Background technology
Along with the adjustment of expanding economy and the structure of rural undertaking, China's all trades and professions constantly rise to the market demand of plastic sheeting, 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 pastings, can also produce clear-cut by the method for vacuum thermoforming, the product of dimensionally stable, then, in the process using, polyurethane film is due to undercapacity, and usually occur that film ruptures, the phenomenon of damage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high-strength polyurethane film, can possess and have high strength, high ductibility, wear-resisting advantage, improves use value.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of high-strength polyurethane film is provided, comprise: the polyurethane coating that is positioned at the superiors, be positioned at middle adhesive and be positioned at undermost inorganic fibre mat, described polyurethane coating is formed by vulcabond and dihydroxyacetone (DHA) addition polymerization, calculate according to mass percent, described vulcabond accounts for 66-72%, described dihydroxyacetone (DHA) accounts for 28-34%, described inorganic fibre mat is mixed by glass fibre and ceramic fibre, calculate according to mass percent, described glass fibre accounts for 55-65%, described ceramic fibre accounts for 35-45%.
In a preferred embodiment of the present invention, described adhesive is pressure sensitive adhesive.
In a preferred embodiment of the present invention, in described polyurethane coating, the concrete proportioning of composition is: described vulcabond accounts for 69%, and described dihydroxyacetone (DHA) accounts for 31%.
In a preferred embodiment of the present invention, in described inorganic fibre mat, the concrete proportioning of composition is: described glass fibre accounts for 60%, and described ceramic fibre accounts for 40%.
The invention has the beneficial effects as follows: the present invention possesses and has high strength, high ductibility, wear-resisting advantage, improves use value.
