Problems solved by technology

[0004] In the prior art, in order to achieve the flame retardant performance of the masterbatch, the flame retardant is generally added directly during the mixing process. Due to the different polarity of the two, it is difficult to disperse the flame retardant in the raw material, and the mixing is uneven, which is easy to cause The flame retardant properties of different parts of the masterbatch are different, and because the flame retardant is in powder form, it is often easy to generate dust pollution during the addition process, which affects the workshop environment and the health of workers

Embodiment

[0046] see figure 1 , a preparation process of flame retardant color masterbatch, comprising the following steps:

[0047] S1. Prepare raw materials: carrier resin, pigments, dispersants, coupling agents, surfactants, plasticizers and flame retardant particles;

[0048] S2. Add the above-mentioned raw materials into the blender, and initially heat the raw materials to break the shell of the dragging flame-retardant grains (such as Figure 5 shown);

[0049] S3, start the mixer to preliminarily mix the raw materials, semi-separate the shell of the wire-drawing flame-retardant pellets, and extrude the powdery flame retardant 7 under pressure, and mix it into the raw materials (such as Figure 6 and Figure 7 shown);

[0050] S4. Carry out secondary heating to the raw material, so that the wire-drawing flame-retardant particles are completely melted in the raw material;

[0051] S5, start the mixer again and carry out the secondary mixing of the raw materials, so that the me...

Abstract

The invention discloses a preparation process of flame-retardant color master batches, and belongs to the field of flame-retardant color master batches, granular wire-drawing flame-retardant particles are prepared by coating a powdery flame retardant, and when the granular wire-drawing flame-retardant particles are mixed with raw materials, not only can the dust problem caused by the flame retardant be effectively avoided and the environmental safety problem be improved, but also the flame-retardant flame-retardant particles can be used for preparing flame-retardant flame-retardant particles. In the mixing process of the wire-drawing flame-retardant particles and the raw materials, the shell-broken wire-drawing flame-retardant particles can be driven by the stirring force of the stirrer to move in the raw materials, and the flame retardant in the wire-drawing flame-retardant particles is extruded under pressure in the moving process and is dispersed in all areas in the raw materials in a multi-point manner; the flame retardant is uniformly diffused in a small range in a nearby area, and the uniform dispersion difficulty of the flame retardant can be greatly reduced and the uniformity of the flame retardant property of the color master batch can be improved in a manner of mixing the whole body and the local part.

Description

technical field [0001] The invention relates to the field of flame-retardant color masterbatches, more specifically, to a preparation process of flame-retardant color masterbatches. Background technique [0002] The full name of color masterbatch is color masterbatch, also called color seed, which is a new type of special colorant for polymer materials, also known as pigment preparation. Color masterbatches are mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in the resin. It can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. When processing, a small amount of color masterbatch and uncolored resin is mixed to achieve the colored resin or product with the designed pigment concentration. [0003] In addition to the above raw materials, functional color masterbatches must be added with a...
