Embodiment 1

[0029] 1) Evenly mix 60 parts by weight of talcum powder, 20 parts by weight of alkyllactam, and an appropriate amount of deionized water, then add them to a planetary ball mill, grind at a speed of 400r / min for 30 minutes, and discharge and filter to obtain a mixture;

[0030] 2) Wash the mixture obtained in step 1) with deionized water, vacuum-dry at 80°C to constant weight after suction filtration, then pulverize and sieve to obtain modified talc powder;

[0031] 3) Add the modified talc powder obtained in step 2), 10 parts by weight of low-density polyethylene, 1 part by weight of paraffin, and 1 part by weight of white oil into a high-speed mixer, and mix for 15 minutes at a speed of 800r / min After discharging, use a twin-screw extruder to plasticize, granulate, heat-cut, and air-cool to make granular masterbatch.

[0032] The prepared transparent filler masterbatch is blended with pure polyethylene at a mass ratio of 1:3, and then made into a film, and the performance in...

Embodiment 2

[0035] 1) Evenly mix 70 parts by weight of talcum powder, 25 parts by weight of alkyldiamine, and an appropriate amount of deionized water, then add them to a planetary ball mill, grind for 45 minutes at a speed of 450 r / min, and filter to obtain a mixture;

[0036] 2) Wash the mixture obtained in step 1) with deionized water, vacuum-dry at 85°C to constant weight after suction filtration, then pulverize and sieve to obtain modified talc powder;

[0037] 3) Add the modified talcum powder obtained in step 2), 15 parts by weight of low-density linear polyethylene, 2 parts by weight of polyethylene wax, and 1 part by weight of white oil into a high-speed mixer, at a speed of 900r / min Mix at low speed for 20 minutes and discharge, plasticize, granulate, heat cut, and air-cooled with a twin-screw extruder to make a granular masterbatch.

[0038] The prepared transparent filler masterbatch is blended with pure polyethylene at a mass ratio of 1:3, and then made into a film, and the per...

Embodiment 3

[0041] 1) Evenly mix 80 parts by weight of talcum powder, 30 parts by weight of alkanolamine, and an appropriate amount of deionized water, then add them to a planetary ball mill, grind for 60 minutes at a speed of 500 r / min, and filter to obtain a mixture;

[0042] 2) Wash the mixture obtained in step 1) with deionized water, vacuum-dry at 90°C to constant weight after suction filtration, then pulverize and sieve to obtain modified talc powder;

[0043] 3) Add the modified talc powder obtained in step 2), 20 parts by weight of polypropylene, 3 parts by weight of oxidized polyethylene wax, and 2 parts by weight of white oil into a high-speed mixer, and mix at a speed of 1000r / min After 30 minutes of discharge, the twin-screw extruder is used for plasticization, granulation, hot cutting, and air cooling to make a granular masterbatch.

[0044] The prepared transparent filler masterbatch is blended with pure polyethylene at a mass ratio of 1:3, and then made into a film, and the...

Abstract

The invention relates to a transparent filling masterbatch and a preparation method thereof. Specifically, the attraction between positive and negative charges is used to embed alkyl groups into the gaps of the talcum powder layered structure, which has the effect of widening the layer spacing. The talc powder processed by the present invention not only has a reduced density, but also can be better dispersed in plastics and has better compatibility with plastics. The processed talc powder, carrier resin, dispersant, etc. are processed through a twin-screw extruder. Plasticizing, granulating, hot-heating, and air-cooling make granular masterbatch. The plastic products produced by adding this masterbatch have lower density, excellent light transmittance and mechanical properties, and have wide application value.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a transparent filler masterbatch and a preparation method thereof. Background technique [0002] The scientific and appropriate use of various fillers in plastic processing can not only save precious synthetic resins made from petroleum, but also improve the performance and performance of plastic materials in certain aspects while reducing the cost of raw materials for plastic products. Give plastic materials new functions, such as increasing their transparency, and transparent filler masterbatch refers to the filler masterbatch that can be used for transparent plastics, that is, the use of this filler masterbatch can not only reduce the cost of plastics, but also improve the transparency of the plastic itself. Sexuality and mechanical properties have little or no influence, and inorganic powder transparent filler masterbatch is the most widely used. Whether inorganic powder can...
