[0039] The invention provides a kind of preparation method of tourmaline polyester masterbatch, comprises the following steps:
[0040] The first step, mixing of tourmaline powder and lubricating dispersant:
[0041] Put the tourmaline powder and the lubricating dispersant into the mixing equipment and mix to obtain a uniform mixture of the tourmaline powder and the lubricating dispersant.
[0042] The first step involves two types of raw materials, namely: tourmaline powder and lubricating dispersant.
[0043] (1) Tourmaline powder. Including manganese tourmaline powder, iron tourmaline powder, lithium tourmaline powder, magnesium tourmaline powder. 6000-mesh powder is preferred, and 10000-mesh powder and 12000-mesh powder are more preferred.
[0044] As we all know, tourmaline is a natural mineral material with a Mohs hardness of 7-7.5, which is harder than steel, teeth, and quartz. The harder the material, the more difficult it is to grind to a finer powder. On the one...

[0057] Example 1: Preparation of PET masterbatch with 10% tourmaline powder content.
[0058] Step 1: Weigh 10 parts of 6000-mesh tourmaline powder and 2.0 parts of lubricating and dispersing agent, and mix them evenly in a mixing equipment. Wherein the dispersing lubricant is hydroxyethyl ethylene bis stearamide. The rotating speed of the mixing equipment is 150 rpm, and the mixing time is 20 minutes. Obtain the homogeneous mixture of tourmaline powder and lubricating dispersant through the first step, totally 12 parts.
[0059] Step 2: Weigh 88 parts of polyethylene terephthalate (PET), and dry them in the drying equipment. After the PET slices are dried, control the moisture content of the slices within 0.1%, and adjust the settings in the dryer. The temperature was 90°C and the PET slices were kept warm. Add 88 parts of PET slices after heat preservation and 12 parts of tourmaline powder and a uniform mixture of lubricating and dispersing agent into the mixing equipment...

[0064] Example 2: Preparation of PBT masterbatch with tourmaline powder content of 20%.
[0065] Step 1: Weigh 20 parts of 6000-mesh tourmaline powder and 5.5 parts of lubricating and dispersing agent, and mix them evenly in a mixing equipment. Wherein the lubricating dispersant is 3.5 parts of hydroxyethyl ethylene bis stearamide, 1.0 part of liquid paraffin, and 1.0 part of polyethylene wax. The rotating speed of the mixing equipment is 150 rpm, and the mixing time is 20 minutes. Obtain the homogeneous mixture of tourmaline powder and lubricating dispersant through the first step, totally 25.5 parts.
[0066] Step 2: Weigh 74.5 parts of polybutylene terephthalate (PBT), and carry out drying treatment in the drying equipment. After the PBT slices are dried, control the moisture content of the slices within 0.1%, and adjust the settings in the dryer. The temperature was 90°C and the PBT slices were kept warm. Add 74.5 parts of PBT slices after heat preservation and 25.5 par...
