Abstract
The invention discloses an anti-ultraviolet film, which includes the following components mixed by weight: 30-60 parts of PET polyester chips, 5-10 parts of an organic ultraviolet absorbent, 5-8 parts of an anti-scratch agent, and 5-8 parts of an anti-adhesion agent. The anti-ultraviolet film provided by the invention contains the organic ultraviolet absorbent, can absorb ultraviolet rays, can be used for making anti-ultraviolet heat-insulating film products, and can be used for ultraviolet protection of automobiles, buildings and the like, thus effectively blocking harmful ultraviolet rays in daily life, and avoiding the harm of ultraviolet on the human body. The invention also discloses a preparation method of the anti-ultraviolet film. By directly extruding the raw materials into sheets after high temperature melting, the coating process is omitted, the production efficiency is improved, time is saved for production, the influence of environmental cleanliness is small, the quality of the anti-ultraviolet film is improved, and the service life is prolonged, so that the film can have the anti-ultraviolet function for a long time.
Description
Technical field
The present invention relates to a kind of antiultraviolet film and preparation method thereof.
Background technology
Along with global warming and the energy day be becoming tight and glass building and automobile on extensive application, functional protective membrane as heat insulation, antiultraviolet, explosion-proof, energy-saving protective film is also more and more important.The energy of sunlight is made up of 53% infrared rays, 44% visible ray and 3% ultraviolet energy, antiultraviolet film mainly plays reflection and sorption to the infrared and ultraviolet line in sunlight, and according to the different respective insulation solar energy of visible light transmittance rate.
Antiultraviolet film of the prior art adopts PET (polyethylene terephthalate) material as base material conventionally, then prepare at pet sheet face coated material, Coating technique is loaded down with trivial details, production efficiency is low, affected by the cleanliness factor of production environment, antiultraviolet film of poor quality, work-ing life is short.

As preferably, organic uv absorbers described in technique scheme is 2,4 dihydroxyl benzophenone.
As preferably, described in technique scheme, anti-scratch dose is any one in magnesium sulfate, kaolin, aluminum oxide, titanium oxide.
As preferably, anti blocking agent described in technique scheme is any one in calcium carbonate, magnesiumcarbonate, barium carbonate.
In order to solve above technical problem, the invention also discloses a kind of preparation method of above-mentioned antiultraviolet film, comprise the following steps:
(1) by described PET polyester slice, described organic uv absorbers, described anti-scratch dose, described anti blocking agent drops in mixing machine in proportion, is warming up to 85～100 DEG C, stirs melting 5～6h, and stirring velocity is 500～2000r/min;
(2) product step (1) being obtained is pre-crystallized within the scope of 150～170 DEG C in temperature, dry 2～5h, and the massfraction of dried water in products is controlled at 5 × 10
-7below;
(3) product step (2) being obtained drops into dual-screw-stem machine and stirs melting 5～6h, and melt temperature is 200～300 DEG C, and described dual-screw-stem machine rotating speed is 100～1500r/min;
(4) product that adopts forcing machine that step (3) is obtained is extruded, and obtains sheet material, then the sheet material of two-way stretch simultaneously, obtains antiultraviolet film.
Antiultraviolet film provided by the present invention, containing organic uv absorbers, can absorb ultraviolet ray, can be for making antiultraviolet thermal isolation film product, can be for the ultraviolet protection such as automobile, building, effectively stop the harmful ultraviolet ray running in daily life, the injury of avoiding ultraviolet ray to cause human body.The preparation method of antiultraviolet film disclosed by the invention, by by direct extruded sheet after raw material high-temperature fusion, reduce the technique of Coating, improve production efficiency, the production of saving time, is affected by the cleanliness factor of environment less, has improved the quality of antiultraviolet film, extend its work-ing life, made it there is for a long time the function of antiultraviolet.
