Problems solved by technology

Because the reflective film plays an obvious warning role with its bright colors in the daytime, at night or in the case of insufficient light, its bright reflective effect can effectively enhance people's recognition ability, see the target clearly, arouse vigilance, and thus avoid accidents , reduce casualties, reduce economic losses, and become an indispensable safety guard for road traffic, which has obvious social benefits. However, in the prior art, the weather resistance of the reflective film is poor and the service life is short, which needs further improvement

preparation example Construction

[0040] Specifically, the preparation method of the transparent protective slurry includes:

[0041] A. Add acetyl tributyl citrate, tributyl citrate, bis(2-ethylhexyl) phthalate, plasticizer TXIB, and heat stabilizer to a high-speed mixer and mix evenly, and set aside;

[0042] B. Pour the polyvinyl chloride paste resin into a high-speed mixer, heat it to 100°C while stirring, then add epoxy soybean oil, diatomaceous earth, titanium dioxide, light calcium carbonate, heavy calcium carbonate, and foaming agent , coupling agent, impact modifier, zinc oxide, after mixing for 5 minutes, add the mixture prepared in step A, and continue mixing for 3 minutes;

[0043] C. Add viscosity reducer D40 to the mixture obtained in step B to adjust the viscosity of the mixture to 1500mPa·s to obtain a transparent protective slurry.

[0044] In the second step, the temperature of the elastic mirror steel roller is 140-160°C, and the temperature of the mold belt is 160-170°C.

Abstract

The invention discloses a manufacturing process of a high-weather-resistance reflective film. The reflective film comprises a transparent protective layer, a microprism layer, a packaging layer, a pressure-sensitive adhesive layer and a release layer which are sequentially arranged from top to bottom, the transparent protective layer is prepared from the following raw materials in parts by weight:polyvinyl chloride paste resin, acetyl tributyl citrate, tributyl citrate, di(2ethylhexyl)phthalate, a plasticizer TXIB, a heat stabilizer, epoxidized soybean oil, diatomite, titanium dioxide, lightcalcium carbonate, ground calcium carbonate, a foaming agent, a coupling agent, an impact modifier and zinc oxide. By limiting plasticizers such as acetyl tributyl citrate, tributyl citrate, di(2ethylhexyl) phthalate and a plasticizer TXIB to be matched with polyvinyl chloride paste resin, the transparent protective layer formed on a microprism is high in plasticizing efficiency, low in plasticizer mobility, good in cold resistance and extraction resistance and high in wear resistance, so that the weather resistance of the reflective film is improved, and the service life of the reflective film is prolonged.

Description

technical field [0001] The invention belongs to the field of reflective film preparation, and in particular relates to a process for producing a highly weather-resistant reflective film. Background technique [0002] Reflective film is mainly used for guide signs, signs, outline signs, raised road signs of various roads and railways, traffic cones, anti-collision tubes, safety islands, mine airport safety signs, place names, license plates, property community safety signs, construction signs, Billboards, stage sets, logos, etc. Because the reflective film plays an obvious warning role with its bright colors in the daytime, at night or in the case of insufficient light, its bright reflective effect can effectively enhance people's recognition ability, see the target clearly, arouse vigilance, and thus avoid accidents , reduce casualties, reduce economic losses, become an indispensable safety guard for road traffic, and have obvious social benefits, but in the prior art, the ...
