Abstract
The present invention relates to a kind of method for improving titanium dioxide Dispersion on surface, the method is as follows：Titanium dioxide, processing aid and PVC resin powder are pressed 50~200：25~100：25~50 mass ratio mixes 3~5min；The processing aid is ACR and/or CPE.The titanium dioxide is rutile type titanium white, and the trade names of the titanium dioxide are NR-950, and the processing aid is ACR and/or CPE.The present invention does not need in addition to buy dispersing agent and increase Jet Mill that the dispersibility on titanium dioxide surface can be improved by the processing aid commonly used in the prior art and PVC resin powder simple blend with certain content.
Description
Technical field
The invention belongs to titanium white production technical fields, and in particular, to a kind of side for improving titanium dioxide Dispersion on surface
Method.
Background technique
Titanium dioxide is easy to build bridge in hopper during using automatic Metage Eguipment, causes weighing deviation big and efficiency
It is low.To solve this problem, it is mentioned in a kind of method for improving titanium dioxide dispersibility of Chinese invention patent CN201610562551.6--
It arrives：In the presence of dispersing agent, titanium dioxide is subjected to air-flow crushing at least twice, dispersing agent is made to integrate more equal with titanium dioxide
It is even, to improve the dispersibility of titanium dioxide.But this method needs in addition to increase dispersing agent and air-flow mixing apparatus, increases enterprise
Production cost.
Therefore, it is necessary to a kind of method for researching and developing simple process, raising titanium dioxide dispersibility at low cost.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of sides for improving titanium dioxide Dispersion on surface
Method, the present invention do not need in addition to buy dispersing agent and increase Jet Mill, by normal in the prior art with certain content
Processing aid and PVC resin powder simple blend, that is, can be improved the dispersibility on titanium dioxide surface.
To achieve the above object, the present invention adopts the following technical scheme that：
A method of titanium dioxide Dispersion on surface being improved, the method is as follows：
Titanium dioxide, processing aid and PVC resin powder are pressed 50~200：25~100：25~50 mass ratio mixes 3~5min；
The processing aid is ACR and/or CPE.
Preferably, the mass ratio of titanium dioxide, processing aid and PVC resin powder is 5:2:1.
Preferably, the titanium dioxide is rutile type titanium white.
Preferably, the trade names of the titanium dioxide are NR-950.
Preferably, the processing aid is ACR.
Compared with prior art, the present invention has the advantages that：
Compared with prior art, the present invention does not need in addition to buy dispersing agent and increases Jet Mill, by containing with specific
The processing aid commonly used in the prior art and PVC resin powder simple blend of amount, that is, can be improved the dispersibility on titanium dioxide surface.
Specific embodiment
Further illustrate the present invention below in conjunction with specific embodiment, but embodiment the present invention is not done it is any type of
It limits.Unless stated otherwise, the present invention uses reagent, method and apparatus is the art conventional reagents, method and apparatus.
Unless stated otherwise, agents useful for same and material of the present invention are commercially available.
Embodiment 1
By 125kg rutile type titanium white NR-950,50kgACR processing aid HL-60 and 25kg PVC resin powder TL-1000,
It is added in the cold mixed cylinder of mixing equipment and mixes 5min.The mixing that the present embodiment is prepared is well dispersed, good fluidity, facilitates title
It measures and is suitable for current formulation ratio.
Embodiment 2
By 125 kg rutile type titanium white NR-950,25 kgACR processing aid HL-60 and 25 kg PVC resin powder TL-
1000, it is added in the cold mixed cylinder of mixing equipment and mixes 3min.The mixing that the present embodiment is prepared is well dispersed, good fluidity,
Facilitate weighing and is suitable for current formulation ratio.
Embodiment 3
By 200 kg rutile type titanium white NR-950,25 kgACR processing aid HL-60 and 50 kg PVC resin powder TL-
1000, it is added in the cold mixed cylinder of mixing equipment and mixes 4min.The mixing that the present embodiment is prepared is well dispersed, good fluidity,
Facilitate weighing and is suitable for current formulation ratio.
Embodiment 4
By 50 kg rutile type titanium white NR-950,100 kgACR processing aid HL-60 and 25 kg PVC resin powder TL-
1000, it is added in the cold mixed cylinder of mixing equipment and mixes 3min.The mixing that the present embodiment is prepared is well dispersed, good fluidity,
Facilitate weighing and is suitable for current formulation ratio.
Comparative example 1
125kg rutile type titanium white NR-950 and 10kg ACR processing aid HL-60 is added in the cold mixed cylinder of mixing equipment
Mix 5min.The titanium dioxide mixture that this comparative example is prepared is easy conglomeration, does not disperse, is unfavorable for weighing.
Comparative example 2
25kg rutile type titanium white NR-950 and 150kg ACR processing aid HL-60 is added in the cold mixed cylinder of mixing equipment
5min is mixed, the titanium dioxide mixture that this comparative example obtains relatively disperses, and is easy to weigh, but the ratio of titanium dioxide and ACR processing aid
Example is not suitable for current formulation ratio.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not intended to limit the present invention the foregoing is merely a specific embodiment of the invention
Protection scope, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
