Problems solved by technology

However, if it is filled into the depression of the rough surface during this process, it will inevitably affect the matting property of the product.
In addition, too fast migration of slip agent will also lead to precipitation, resulting in rough surface of the product, which will affect the smoothness on the contrary.

Embodiment 1

[0033] A method for preparing a high-smooth PP and PE matting masterbatch. First, 20 kg of polypropylene, 0.3 kg of matting agent, and 1 kg of smoothing agent are first blended, extruded and granulated to obtain modified polypropylene, and then granulated. Modified polypropylene, 65kg polyethylene and 0.3kg coupling agent are extruded and granulated for the second time to obtain a high smoothness PP and PE matting masterbatch; wherein, the matting agent is obtained by the following method Prepared:

[0034] (A) first soaking the polyethersulfone resin in the Sphingomonas bacterial liquid, fermenting and modifying, and centrifuging to obtain the modified polyethersulfone resin;

[0035] (B) then slowly add ethyl orthosilicate dropwise to the hydrochloric acid solution of pH=4, stir evenly and then heat up to 65°C, stir at 500 r / min for 18 hours, then add the modified polyethersulfone resin obtained in step (A), Stir at 1200 r / min for 5 hours to obtain gel, and post-processing ...

Embodiment 2

[0047] A preparation method of high-smooth PP and PE matting masterbatch, firstly, 25kg polypropylene, 0.2kg matting agent and 2kg slipping agent are mixed, extruded and granulated for the first time to obtain modified polypropylene, and then Modified polypropylene, 50kg polyethylene and 0.4kg coupling agent are extruded and granulated for the second time to obtain a high smoothness PP and PE matting masterbatch; wherein, the matting agent is obtained by the following method Prepared:

[0048] (A) first soaking the polyethersulfone resin in the Sphingomonas bacterial liquid, fermenting and modifying, and centrifuging to obtain the modified polyethersulfone resin;

[0049] (B) then slowly dropwise add ethyl orthosilicate to the hydrochloric acid solution of pH=3, stir evenly and then heat up to 75°C, stir at 300 r / min for 20 hours, then add the modified polyethersulfone resin obtained in step (A), Stir at 1000 r / min for 8 hours to obtain a gel, and post-processing to obtain th...

Embodiment 3

[0061] A method for preparing a high-smooth PP and PE matting masterbatch. First, 22 kg of polypropylene, 0.25 kg of matting agent and 1.5 kg of smoothing agent are first blended, extruded and granulated to obtain modified polypropylene, and then The modified polypropylene, 60kg polyethylene and 0.35kg coupling agent are extruded and granulated for the second time to obtain a high smoothness PP and PE matting masterbatch; wherein, the matting agent is obtained by the following method: prepared by the method:

[0062] (A) first soaking the polyethersulfone resin in the Sphingomonas bacterial liquid, fermenting and modifying, and centrifuging to obtain the modified polyethersulfone resin;

[0063] (B) then slowly dropwise add ethyl orthosilicate to the hydrochloric acid solution of pH=4, stir evenly and then heat up to 70 ° C, stir at 400 r / min for 19 hours, then add the modified polyethersulfone resin obtained in step (A), Stir at 1100 r / min for 6 hours to obtain gel, and post...

Abstract

The invention provides a high smoothness PP and PE matting masterbatch, preparation method and application. Firstly, polypropylene, matting agent and smoothing agent are blended, extruded and granulated for the first time to obtain modified polypropylene. Then, the modified polypropylene, polyethylene and coupling agent are blended and extruded for the second time to obtain a high smoothness PP and PE matt masterbatch. The technical key lies in the proportion of polypropylene and polyethylene. The adjustment of the relationship and the improvement of the matting agent and the smoothing agent give consideration to the matting and smoothness of the obtained product, and have excellent marketing value.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high-smooth PP and PE matting masterbatch, a preparation method and an application. Background technique [0002] Plastic film is a very important flexible packaging material in today's society. With the development of society and the improvement of economic level, people's requirements for packaging materials are getting higher and higher. People expect packaging materials to have better feel and visual effects, and smoothness. and extinction are two important technical indicators corresponding to it. [0003] At present, there are some matte film products on the market. This is a packaging film with high haze and low gloss, and the surface can form a diffuse reflection matte effect. The surface reflection is weak and soft. Patent application CN107082931A discloses a matting masterbatch for CPP film, which is made of polypropylene, polyethylene, antioxidants, fille...
