Problems solved by technology

[0002] Polyethylene terephthalate (PET) is a kind of linear polyester, which is often used as a raw material for extruded films and shed films. However, due to the relatively high glass transition temperature and melting point of PET, the crystallization speed is relatively slow, and the products The surface is rough, the gloss is poor, the impact toughness is not good, and there are problems such as easy aging

Embodiment 1

[0019] A core-shell toughening anti-aging masterbatch for PET film, its components are proportioned by mass percentage: PET resin 18%, ultrafine powder tremolite 40%, TPE elastomer 20%, acrylic acid 4%, even 2% nitrogen bisisobutyronitrile, 10% 2-hydroxy-4-methoxybenzophenone, 1.5% talc powder with a particle size between 0.01 μm and 5 μm, 4% polyethylene glycol, hindered phenol antioxidant 0.5% compound of agent 1010 and phosphite antioxidant 168. The ultrafine powdered tremolite is a natural coexisting inorganic ore formed after the mixed deposition of dolomite and quartz, which is superfinely pulverized into a powder with a particle size of 1000 mesh to 3000 mesh, and its relative density is 2.9 to 3.2g / cm 3 .

[0020] Preparation method: (1) Dry the PET at 130°C-140°C for 3-5 hours, and dry the ultra-fine powdered tremolite at 105°C-120°C for 1-2 hours, then use; (2) Prepare by weight Add the dried ultrafine powder tremolite into a high-speed mixer with a barrel temperat...

Abstract

The invention discloses a PET (polyethylene terephthalate) film-use core shell toughened aging-resistant master batch and a preparation method thereof. The PET film-use core shell toughening aging-resistant master batch comprises the following components by mass: 15%-30% of PET resin, 30%-50% of superfine powder tremolite, 20%-40% of TPE (thermal plastic elastomer), 2%-6% of acrylic acid, 1%-3% of azodiisobutyronitrile, 10%-20% of a light stabilizer, 0.5%-2% of a nucleation agent, 3%-5% of a lubricant and 0.1%-2% of an antioxidant. The tremolite is pretreated, by interaction and grafting reaction of the pretreated tremolite and the TPE, a TPE chemically-coated superfine powder tremolite core-shell structure is formed, respective advantages and very good synergistic toughening and strengthening effects can be played, and the PET film-use core shell toughening aging-resistant master batch has the characteristics of good anti ageing modification effect, and can be widely applied to the field of PET film production.

Description

technical field [0001] The invention relates to a masterbatch and a preparation method thereof, in particular to a core-shell toughened aging-resistant masterbatch for a PET film and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a kind of linear polyester, which is often used as a raw material for extruded films and shed films. However, due to the relatively high glass transition temperature and melting point of PET, the crystallization speed is relatively slow, and the products The surface is rough, the gloss is poor, the impact toughness is not good, and there are problems such as easy aging. Therefore, considering how to prolong the service life and improve its mechanical strength has become the key to the modification of PET film. Contents of the invention [0003] The purpose of the present invention is to provide a core-shell toughened anti-aging masterbatch for PET film and its preparation method, which has the char...
