Abstract

The invention discloses a coloring master batch for a profile protective film, belonging to the field of plastic additives. The master batch comprises the following raw materials in percentage by mass: 60-75% of titanium dioxide, 15-30% of LLDPE (linear low density polyethylene), 5-10% of mPE, 0.3-0.5% of silicone and 4-10% of EVA, wherein the volatilization amount of low molecular weight organic matters of titanium dioxide is less than or equal to 0.15%; and titanium dioxide is rutile type titanium dioxide, and the average particle size is 0.2-0.25 micron. The invention also discloses a preparation method of the coloring master batch. Compared with a conventional preparation method, the preparation method is lower in temperature of extrusion processes, and can be used for effectively controlling the volatilization amount of low molecular weight matters. The coloring master batch disclosed by the invention has the advantages that the coloring master batch has high titanium dioxide content, large adding proportion, high dispersion performance and good shading effect; film products are smooth and do not have crystal points; the low molecular weight organic matters are low in volatilization amount; and the coloring master batch is good in printing ink and gluing adhesive force and convenient to use, and low-temperature processing, energy conservation, high efficiency and low cost can be achieved.

Description

technical field [0001] The invention relates to a polyethylene coloring masterbatch, in particular to a coloring masterbatch for a profile protective film and a preparation method thereof, belonging to the field of plastic additives. Background technique [0002] In 2012, my country produced about 5.2 million tons of various types of plastic doors and windows, profiles, and profiles. In order to achieve the purpose of promoting and protecting the surface of profiles, it is necessary to glue and print films with packaging and promotional materials on the surfaces of profiles. In order to achieve this purpose and reduce the cost as much as possible, the profile protective film should be produced thinly and be able to block light. In the process of film blowing, a large amount of traditional coloring masterbatch and filling masterbatch are added. However, the following problems exist in the production of profile protective films by using masterbatches produced by traditional t...
