Problems solved by technology

[0002] Plastic colored colored sand is used as a colorant in synthetic materials such as plastics, rubber, paints, and inks. It has high dispersibility and high phase solubility, and has functional characteristics such as small dosage, non-toxic, and dust-free. It is widely used in It is a new type of environmentally friendly functional material in the fields of household appliances, electronics, wire and cable, food packaging, etc. Calcium carbonate is added to the existing color sand formula, but calcium carbonate has the disadvantages of being not resistant to acid and aging, which makes The scope of use of colored sand with this formula is limited

Embodiment 1

[0008] Provided is a kind of plastic coloring sand, and the ratio of the parts of each component is: masterbatch pigment 30; low molecular weight polyethylene 20; nanometer BaSO410; titanium dioxide 30.

[0009] Due to the poor dispersibility of titanium dioxide, the surface of titanium dioxide is generally treated with an organic treatment agent. The organic treatment agent generally uses triethanolamine, sorbitol, mannitol, polyethylene glycol, polypropylene glycol, alkyl chlorosilane, Ester compounds, fatty acid compounds, etc.; the processing technology is: put the masterbatch pigment and titanium dioxide in the internal mixer for about 15 minutes, use titanium dioxide and the masterbatch pigment as the base material, add low molecular weight polyethylene to disperse function, add nano-BaSO4 to improve dispersion, pour out after the material is completely melted, cut into 10-20 cm blocks, cool under natural conditions, put them into a pulverizer for crushing, and then put t...

Embodiment 2

[0010] Embodiment 2: Provide a plastic colored colored sand, the ratio of the parts of each component is: 40 masterbatch pigments; 20 low molecular weight polyethylene; nanometer BaSO410; titanium dioxide 20.

[0011] Due to the poor dispersibility of titanium dioxide, the surface of titanium dioxide is generally treated with an organic treatment agent. The organic treatment agent generally uses triethanolamine, sorbitol, mannitol, polyethylene glycol, polypropylene glycol, alkyl chlorosilane, Ester compounds, fatty acid compounds, etc.; the processing technology is: put the masterbatch pigment and titanium dioxide in the internal mixer for about 15 minutes, use titanium dioxide and the masterbatch pigment as the base material, add low molecular weight polyethylene to disperse function, add nano-BaSO4 to improve dispersion, pour out after the material is completely melted, cut into 10-20 cm blocks, cool under natural conditions, put them into a pulverizer for crushing, and then...

Embodiment 3

[0012] Embodiment 3: Provide a plastic colored colored sand, the ratio of the parts of each component is: 20 masterbatch pigments; 10 low molecular weight polyethylene; nanometer BaSO420; titanium dioxide 50.

[0013] Due to the poor dispersibility of titanium dioxide, the surface of titanium dioxide is generally treated with an organic treatment agent. The organic treatment agent generally uses triethanolamine, sorbitol, mannitol, polyethylene glycol, polypropylene glycol, alkyl chlorosilane, Ester compounds, fatty acid compounds, etc.; the processing technology is: put the masterbatch pigment and titanium dioxide in the internal mixer for about 15 minutes, use titanium dioxide and the masterbatch pigment as the base material, add low molecular weight polyethylene to disperse function, then add nano BaSO4 to improve dispersion, pour out after the material is completely melted, cut into 10-20 cm blocks, cool under natural conditions, put them into a pulverizer for crushing, and...

Abstract

The invention discloses a plastic colored sand and a processing technique thereof. The plastic colored sand is prepared from 20-30 parts of color master batch pigment, 20-30 parts of low-molecular weight polyethylene, 10-20 parts of nano BaSO4 and 30-50 parts of titanium dioxide. The processing technique comprises the following steps: by using the titanium dioxide and carbon black as base materials, adding the low-molecular weight polyethylene to perform dispersion function, adding the nano BaSO4 to improve the dispersity, banburying, cooling, pulverizing and milling to obtain the product. The plastic colored sand has the advantages of favorable coloring power, favorable dispersity, no pollution and the like, is convenient for measurement, does not change the physical properties of the plastic, and can be widely used in plastics, rubber, chemical fibers, wire cables and other industries.

Description

technical field [0001] The invention relates to a pigment dye, in particular to a plastic colored sand and a processing technology. Background technique [0002] Plastic colored colored sand is used as a colorant in synthetic materials such as plastics, rubber, paints, and inks. It has high dispersibility and high phase solubility, and has functional characteristics such as small dosage, non-toxic, and dust-free. It is widely used in It is a new type of environmentally friendly functional material in the fields of household appliances, electronics, wire and cable, food packaging, etc. Calcium carbonate is added to the existing color sand formula, but calcium carbonate has the disadvantages of being not resistant to acid and aging, which makes The range of use of colored sand with this formula is limited. Contents of the invention [0003] The object of the present invention is to provide a kind of plastic colored colored sand with high dispersibility and high phase meltin...
