Abstract
The invention provides a scratching resisting screen protecting thin film. The scratching resisting screen protecting thin film comprises the following components in parts by weight: 30-35 parts of polypropylene resin, 15-18 parts of polyethylene terephthalate, 10-13 parts of polyfluortetraethylene powder, 5-8 parts of maleic anhydride grafted polypropylene, 8-10 parts of tributyl citrate, 2-4 parts of epoxidized soybean oil and 0.2-0.5 part of stabilizing agent. The scratching resisting screen protecting thin film has good scratching resistance through reasonable compounding of the polypropylene resin, the polyethylene terephthalate and the polytetrafluoroethylene under the combined action of other additives. After the scratching resisting screen protecting thin film is normally used for 6 months on the surface of a screen, no small scratching traces occur on the surface.
Description
Technical field
The invention belongs to paint field, be specifically related to a kind of scratch-resistant type screen protection film.
Background technology
Current existing screen protection film mostly is OPP or BOPP, can effectively protect the neat and tidy of screen and keep the no marking of screen own.But the resistance to marring of general thin itself is poor, very easily there is scratching vestige in surface, brings very large puzzlement to user, and well behaved scratch resistance film is comparatively expensive, make its use be subject to certain limitation, therefore it is just particularly important to develop a kind of well behaved resistance to marring film of cheapness.
In sum, how to overcome the deficiencies in the prior art and become existing field problem demanding prompt solution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and propose a kind of scratch-resistant type screen protection film, the present invention has good resistance to marring.
Technical scheme of the present invention is as follows:
Scratch-resistant type screen protection film, comprises the following raw material according to mass fraction meter: acrylic resin 30-35 part, polyethylene terephthalate 15-18 part, polytetrafluoroethylene powder 10-13 part, maleic anhydride inoculated polypropylene 5-8 part, tributyl citrate 8-10 part, epoxy soybean oil 2-4 part, stablizer 0.2-0.5 part.
Described scratch-resistant type screen protection film, comprises the following raw material according to mass fraction meter: 33 parts of acrylic resins, 16 parts of polyethylene terephthalates, 12 parts of polytetrafluoroethylene powders, 6 parts of maleic anhydride inoculated polypropylenes, 9 parts of tributyl citrates, 3 parts of epoxy soybean oils, 0.4 part of stablizer.
Described scratch-resistant type screen protection film, wherein said stablizer is the one in liquid barium zinc stabilizer or liquid calcium zinc stabilizer.
Preparation method of the present invention: according to quality proportioning, by even in high-speed mixer and mixing each raw material, deliver to forcing machine, extruder temperature is controlled at 150-165 ℃, after material is delivered to plastics processing mill, material loading is to rolling press again, and rolling press temperature is 140-150 ℃, through calendering, sizing, cooling, curling, cut, pack and get final product to obtain finished product.
beneficial effect:the present invention is rationally composite by acrylic resin, polyethylene terephthalate and polytetrafluoroethylene powder, under the acting in conjunction of other auxiliary agents, make film of the present invention there is good scratch-proofness, film is in the normal use of screen surface after 6 months, and surface is without tiny wiping cut.
