Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to solve the existing PVC granulation or calendering production process, directly adding pigments for mixing, which may easily cause defects on the surface of PVC granules, tablets or films, and cause serious environmental pollution on the production site. Problem, the present invention provides an environmentally friendly PVC color paste and its manufacturing method. The manufacturing method of the present invention is simple and environmentally friendly, and the pigment and plasticizer are completely compatible. Type PVC color paste, will not cause production environment pollution, will not cause surface defects of granules, tablets or films, can improve its dispersion and coloring effects in PVC mixtures, and improve the gloss of granules, tablets or films

Embodiment 1

[0014] Example 1: Add 25Kg epoxidized soybean oil into the disperser and heat up to 30°C, gradually add 75Kg of carbon black, heat up to 60°C while stirring, stop mixing, discharge, and disperse and mix the mixture The material is added into a three-roller mill for grinding until the particle size of the pigment particles is 8nm to obtain an environmentally friendly PVC color paste, which is discharged, cooled and packaged.

Embodiment 2

[0015] Example 2: Add 20KG epoxidized soybean oil into the disperser and heat up to 30°C, gradually add 80KG carbon black, heat up to 60°C while stirring, stop mixing, discharge, and mix the mixed The material is added into a three-roller mill for grinding until the particle size of the pigment particles is 8nm to obtain an environmentally friendly PVC color paste, which is discharged, cooled and packaged.

Embodiment 3

[0016] Example 3: Add 10KG dioctyl phthalate into the disperser and heat up to 30°C, gradually add 90KG titanium dioxide, heat up to 60°C while stirring, stop mixing, discharge, and disperse and mix The final mixture is added to a three-roll mill for grinding until the particle size of the pigment particles is 12nm to obtain an environmentally friendly PVC color paste, which is discharged and packaged after cooling.

Abstract

The invention relates to an environment-friendly PVC color sizing and the preparation method, comprising pigment with 10 to 50 mass percent and plasticizer with 50 to 90 mass percent. The PVC color sizing adopts the following preparation method and technological process: a) dispersing and mixing, namely putting the pigment and the plasticizer into a dispersion machine to disperse and mix; b) grinding, namely grinding the mixture after dispersing and mixing to obtain the environment-friendly PVC color sizing. The environment-friendly PVC color sizing has the advantages of simple preparation method and good environmental protection performance. The pigment and the plasticizer can be compatible with each other throughly. The preparation method can be used in PVC prilling and calendering producing process without any environmental pollution, and also has the advantages of smoothing the surface of the PVC granules or pellets or films, improving the dispersing effect and pigmentation effect in the PVC mixture and increasing the lustrousness of the PVC granules or pellets or films.

Description

technical field [0001] The invention relates to an environment-friendly PVC color paste and a manufacturing method thereof. Background technique [0002] In the traditional PVC granulation and calendering production process, pigments are often added directly for mixing, which can easily cause defects on the surface of PVC granules, tablets or films, and directly adding pigments to the mixture will cause production workshops and weighing Dust is flying in the measurement position, polluting the production environment, causing great troubles to product quality and on-site management. The traditional color masterbatch production process is too complicated, resulting in high production costs. At the same time, too many additives added will lead to PVC granulation or calendering, and repeated use of PVC additives will make the finished product unstable. Contents of the invention [0003] The technical problem to be solved by the present invention is: to solve the existing PVC ...
