Description

A super-concentrated carrier-free plastic masterbatch and its preparation process and production system

technical field

The invention relates to a super-concentrated non-carrier plastic masterbatch, a preparation process and a production system thereof.

Background technique

In the current plastic masterbatch industry, the traditional components of the masterbatch are: the colorant is compounded with the resin of the cured plastic as the carrier and the same dispersant is added, for example: the masterbatch of PE plastic is composed of the colorant +PE resin+polyethylene wax dispersant. The basic process of the traditional masterbatch preparation process is: 1) dry powder high-speed mixer mixing/internal mixer internal mixing; 2) twin-screw/single-screw extruder melting granulation; 3) granulation, the masterbatch produced by this formula process is in At present, the market can basically meet the requirements of color matching, performance, and dispersion; but in recent years, with the continuous improvement of the appearance and quality requirements of packaging products, the masterbatch produced by traditional formula technology is used in pearlescent packaging products and polyethylene terephthalic acid. Plastics, such as PET material color translucent/solid color products have great limitations:

1. For packaging products containing pearlescent pigments, due to the traditional process of melt extrusion and granulation through twin-screw/single-screw extruders, the unique high-strength shear force of the extruders seriously damages the integrity of the pearlescent pigment structure, and cannot Reflecting the high-gloss and high-shine effect of the pearlescent pigment itself, the pearlescent effect of the final product is greatly weakened, resulting in high cost and low effect.

2. In the color translucent/solid color products of PET and other materials, the traditional masterbatch is to load inorganic titanium dioxide and organic dyes on the PET material for granulation; because the inorganic titanium dioxide is loaded on the PET material in the form of tiny particles , and organic dyes are dissolved in PET materials in molecular form. When traditional masterbatches are added to PET materials, the diffusion rate of inorganic titanium dioxide particles is much lower than that of organic dyes, resulting in different degrees of color streaks on the product, which seriously affects The appearance and quality of the products caused a high defect rate.

3. The use of traditional masterbatch is limited by the carrier of the masterbatch. The material of the carrier resin used in the masterbatch must basically be consistent with the material used downstream. The use of the masterbatch is relatively limited; the carrier accounts for 15-99% of the masterbatch , The amount of petrochemical raw materials used is relatively large.

Mechanism of the present invention and beneficial effect:

1. The traditional color masterbatch is a pigment concentrate with resin as the carrier. The pigment exists in three states: primary particles, aggregates and aggregates. The dispersion mechanism of the pigment is the process of breaking the aggregate particles into aggregates and primary particles, and stabilizing the newly generated particles. The dispersion process of the pigment in the resin can be represented by the following three steps: first, the resin melt wets the surface of the pigment aggregate and penetrates into the internal pores; secondly, the external shear force and the mutual impact between the pigment particles The agglomerates are broken under the action of collision; finally, the newly formed pigment particles are wetted and coated by the resin melt, and are stable and no longer agglomerated. However, due to the high viscosity of the resin melt and poor compatibility with the surface of the pigment, the wettability is poor, and it is difficult to penetrate into the pores of the aggregate, so the shear force cannot be effectively transmitted, and it is difficult to break the aggregate well. After the aggregates are broken, the resin melt cannot quickly wet and protect the new surface, and the collision and contact with each other will make the particles re-aggregate. In order to solve this problem, the present invention uses dispersing agents such as pentaerythritol stearate (PETS), stearic acid or stearate as the carrier substances of pigments, compared with base resin, in molten state PETS, stearic acid or Stearate has lower melt viscosity, stronger penetration performance, and good compatibility with pigments; it can well wet the pigments and penetrate into the internal voids of pigment aggregates during the melt blending process, eliminating The internal stress of the aggregate makes it easier for the pigment to open under the action of external shear force, and the compounded polyethylene wax and coupling agent in the formula greatly improve the flow capacity of the system, so that the newly formed pigment particles can be absorbed more quickly Wetting and protecting, preventing the re-agglomeration of the particles, improving the dispersion degree of the pigment in the whole system; and the addition of the coupling agent greatly improves the lipophilicity of the pigment surface, which makes the pigment particles in the whole system and The compatibility of polyethylene wax and dispersant has been greatly improved, so that the dispersibility of the whole system is much higher than that of traditional masterbatches, and the amount of colorant can be greatly increased. The super-concentrated masterbatch made is In the follow-up application, it can be dispersed into various plastic carriers to prepare different plastic products. It has strong versatility and a wide range of applications. It changes the limitations of the traditional masterbatch due to the limitation of the carrier, so that the masterbatch can be used at the same time. It is used in a variety of materials to reduce the use of petrochemical raw materials in the masterbatch and achieve the purpose of energy saving and environmental protection.

2. The present invention can improve the problems of severe shearing of the pearl effect of traditional masterbatches and poor dispersion of colored semi-permeable/solid-color products of colored masterbatches by crushing materials and granulating them: it can maximize The integrity of the pearlescent raw material particle structure is retained to the maximum extent. Under the same pearlescent raw material content, the pearlescent effect of the final product is 3-5 times that of the traditional process.

In the color translucent/solid color products made of PET and other materials, this production process avoids the limitation of the plastic carrier in the traditional process, solves the dispersion problem caused by the different secondary diffusion rates of inorganic titanium dioxide and organic dyes, and can completely solve the problem. The problem of toner streaks in the final product has achieved zero defect rate.

3. The production system of the present invention adapts to the preparation process of super-concentrated carrier-free plastic master batches by combining a high-speed mixer or internal mixer, a pulverizer, and a tablet press to ensure the integrity and continuity of the process while realizing automation and high efficiency.
