Problems solved by technology

However, the main components of flat yarn are polypropylene and polyethylene, and wollastonite powder is hydrophilic and oleophobic. If wollastonite powder is filled into it in powder form, the compatibility between the two will be poor and the mixing will be uneven. , can not carry out effective high-concentration filling, nor can it achieve the purpose of improving the quality of flat wire and improving the performance of flat wire products

Embodiment 1

[0050] Wollastonite powder modified filler masterbatch for flat yarn is made by mixing polypropylene carrier and masterbatch according to the following weight percentages, and extruding and granulating through twin-screw extruder:

[0051] Masterbatch 35%;

[0052] Polypropylene carrier 65%;

[0053] Wherein, masterbatch is made up of the raw material of following weight part:

[0054] 50 parts of wollastonite powder of 1600 mesh to 2500 mesh;

[0055] 1 part activator;

[0056] 1.5 parts of dispersant;

[0057] 2 parts lubricant;

[0058] The activator is any one or a mixture of more than one of silane coupling agent, stearic acid, polyethylene glycol, and higher fatty alcohol polyoxyethylene ether.

[0059] The effect of each raw material component of above-mentioned formula is as follows:

[0060] Wollastonite powder: It is more appropriate to choose 1600 mesh to 2500 mesh. The wollastonite powder must be dispersed, activated and packaged well, otherwise dust will app...

Abstract

The invention relates to the technical field of polymer composite materials for producing flat yarns, in particular to a wollastonite powder-modified filler masterbatch for flat yarns and a method for producing flat yarns. ~70 parts; 1~2 parts of activator; 1~5 parts of dispersing agent; Strength and bending strength, the quality of flat wire products is greatly improved, and the production cost of raw materials is reduced.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials for producing flat yarns, in particular to a wollastonite powder-modified filler masterbatch for flat yarns and a method for producing flat yarns. Background technique [0002] Flat yarn is the basic material for the production of plastic braids. It is mainly made of polymer materials such as polypropylene and polyethylene resin through specific processes. In the prior art, in order to reduce the production cost of flat yarn and improve the performance of polymer materials, inorganic minerals with calcium carbonate and talcum powder are usually selected as filler masterbatches, but the chemical composition, crystal structure and particle shape of the above-mentioned inorganic mineral fillers Determine its filling performance, because the material of calcium carbonate is granular, and the material of talcum powder is flake, if the addition ratio is inappropriate, the tensile str...
