Abstract
The invention relates to a method for preparing multifunctional calcium carbonate master batch. The master batch is compounded by the following components in part by mass: 15 to 30 parts of polyolefin, 50 to 75 parts of calcium carbonate, 10 to 20 parts of polyethylene wax, a coupling agent in an amount of 0.25 to 3 percent of the calcium carbonate, a lubricating dispersant in an amount of 1.0 to 2.0 percent of the calcium carbonate, and a thinning agent in an amount of 0.5 to 6 percent of the calcium carbonate. The invention also introduces a preparation process for the calcium carbonate master batch. The preparation method has the advantages that: the master batch is easy to process, the cost is low and the like. The calcium carbonate master batch prepared by the method can be directly used in the aspects such as polyolefin resin mixed injection, blending modification and the like, and has a wide application prospect.
Description
Technical field
The present invention relates to a kind of preparation method of multi-functional lime carbonate master batch.
Background technology
Lime carbonate is a kind of important plastic filler, owing to have cheap, nontoxic, good chemical stability, it adds in plastics can play increment, reduce cost, improve goods impelling strength, improve effect such as dimensional stability, therefore has a wide range of applications in plastics.
Because lime carbonate is inorganic particulate, and is relatively poor with Compatibility in Plastics.Lime carbonate directly adds in the plastics relatively poor to its modified effect, and dust is more in the course of processing is unfavorable for cleaner production, lime carbonate being made master batch can improve in the consistency of lime carbonate and plastics and the course of processing and do not have dust, is a kind of scheme that solves unfavorable factor in the lime carbonate course of processing preferably.Therefore at present generally plastics are carried out modification with the lime carbonate master batch.
But the lime carbonate master batch of Xiao Shouing is generally toughness reinforcing lime carbonate master batch in the market, and plastics are had certain toughening effect.But its dispersed relatively poor in plastics, and the flowability to plastics produces bigger influence in toughness reinforcing, is unfavorable for the injection moulding of plastics.(whether please help me to have a look this section narration conflicts with my patent name)
At present a lot of enterprises directly carry out technologies such as injection moulding, blown film, hollow blow molding, wire drawing after adopting and directly adding the blending of lime carbonate master batch with resin.But, add lime carbonate master batch 30% back goods and flaws such as inequality, white point will occur disperseing because present lime carbonate master batch dispersiveness is relatively poor.
Summary of the invention
The technical problem to be solved in the present invention is the shortcoming that overcomes prior art, and a kind of preparation method who is easy to disperse high filling, multiple use, simple a kind of multi-functional lime carbonate master batch that has is provided.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of preparation method of multi-functional lime carbonate master batch is characterized in that, forms by following component is composite:
(1) polyolefine 15-30 mass parts;
(2) lime carbonate 50-75 mass parts;
(3) polyethylene wax 10-20 mass parts;
(4) 1.0%-2.0% of lubrication dispersing agent lime carbonate quality;
(5) 0.25%-3% of coupling agent lime carbonate quality;
(6) thinner lime carbonate quality 0.5%-6%;
(7) oxidation inhibitor 0.5-2.0 mass parts
Described polyolefine is the mixture of polyethylene or polypropylene or polyethylene and polypropylene arbitrary proportion;
Described lime carbonate is water-ground limestone or light calcium carbonate, and particle diameter is micron or submicron order;
Described polyethylene wax molecular weight is 1000-5000;
Described lubrication dispersing agent is fats or aliphatic amide type or ester class dispersion agent;
Described coupling agent is titanate coupling agent or aluminate coupling agent;
Described thinner is the thinner of used coupling agent, and materials are white oil or Virahol.
A kind of preparation method of multi-functional lime carbonate master batch comprises the steps:
1) under 80-120 ℃ of condition, lime carbonate was carried out dry 1-2 hour;
2) lime carbonate that will be after drying and polyethylene wax, lubrication dispersing agent drop into and mix churning time in the mixing machine is 2-10 minute;
3) coupling agent is carried out high-speed stirring with the thinner dilution back the adding in the high-speed mixer, churning time is 30-90 minute, promptly obtains after the high-speed stirring through the treated carbonates after the coupling modification;
4) treated carbonates after the modification, polyolefine and oxidation inhibitor are added in the stirrer in certain proportion, mix to stir 3-10 minute, then through plastics extruder extrude, granulation promptly obtains this lime carbonate master batch.
The present invention has following advantage:
The present invention adopts thinner, coupling agent, dispersion agent that lime carbonate is handled, it is compatible and be uniformly dispersed with plastic substrate better to make lime carbonate have activity, white oil or Virahol are the thinner of coupling agent and certain lubrication are arranged, and can help the dispersion of lime carbonate in matrix with the dispersion agent synergy.Polyethylene wax in the matrix is a kind of macromolecule wax, can improve the glossiness and the processibility of product, and polyethylene wax also is a kind of lubricant, and certain lubrication is also arranged in the present invention.This is adopted the method for certain technology utilization blend to prepare the lime carbonate master batch.Show that through verification experimental verification this master batch effect in technologies such as blending and modifying, injection moulding, hollow blow molding, wire drawing is good.It is still better that this lime carbonate master batch adds 50% dispersion in above-mentioned technology, flaws such as inequality, white point occur disperseing.
Embodiment
In order to describe the present invention, provide following embodiment.
With 100KG lime carbonate master batch is example, and its preferred ingredients is:
(1) polyolefine 22 mass parts;
(2) lime carbonate 65 mass parts;
(3) polyethylene wax 7.5 mass parts;
(4) lubrication dispersing agent 0.9 mass parts;
(5) coupling agent 1.2 mass parts;
(6) thinner 2.4 mass parts;
(7) oxidation inhibitor 1 mass parts.
Comprise the steps:
1) under 80-120 ℃ of condition, lime carbonate was carried out dry 1-2 hour;
2) lime carbonate that will be after drying and polyethylene wax, lubrication dispersing agent drop into and mix churning time in the mixing machine is 2-10 minute;
