Description
Technical field
The present invention relates to a kind of high uniformity high metal content agglomerate preparation methods, belong to master-batch techniques field.
Background technique
Currently, maximum problem is the dispersion of metal powder granulates in inorganic pigment in the Masterbatch containing inorganic pigment
Performance is bad, since the roll spacing of kneading machine in traditional handicraft is excessive, has Component Vectors resin agitating uneven, simultaneously because friction
Effect, so that the excessively high bad control of roller temperature, so that carbon gel solids is excessive, and in extrusion process, it equally can be because of height
Temperature and form carbonization stain, cause mix between inorganic pigment powder and vector resin in most master batches unevenly, so that making
It cannot accurately guarantee the additive amount of inorganic pigment with when Masterbatch, and influence the color of product.
Summary of the invention
Technical problem to be solved by the present invention lies in: a kind of high uniformity high metal content agglomerate preparation method is provided,
It solves the problems, such as to mix between inorganic pigment powder and vector resin in most master batches non-uniform.
The technical problems to be solved by the invention take following technical scheme to realize:
A kind of high uniformity high metal content agglomerate preparation method, comprising the following steps:
S1. it is put into distilled water in a kettle, then inorganic pigment powder is added in reaction kettle and carries out continuing stirring, revolving speed
For 200~500r/min, inorganic pigment powder and distilled water is made to be mixed into suspension；
S2. vector resin and dispersing agent are put into the suspension in stirring, pressurized, heated processing then is carried out to suspension, is added
Pressure range is 0.8~2.2MPa, and heating temperature is 160~210 DEG C, is sufficiently stirred；
S3. after stirring evenly, the material in reaction kettle is cooled down, then after taking out solidification in cooling distilled water
Vector resin will be broken into particle after vector resin drying, then remove tiny break flour through Vibration Screen, obtain master batch.
As preferred embodiment, ingredient used is by weight are as follows: distilled water is 40~70 parts, vector resin is 10~40
Part, inorganic pigment powder are 15~50 parts, and dispersing agent is 0.1~0.4 part.
