Description
Technical Field
The invention relates to the technical field of plastic manufacturing, in particular to a manufacturing method of color master batches added with calcium oxide and a manufacturing method of the color master batches added with calcium oxide.
Background
Calcium oxide is called Filler (Filler) or Extender (Extender) abroad.
At present, the main goal of adding calcium oxide is to reduce the cost of plastics, and with the improvement of the surface properties and the controllability of shape and particle size of calcium oxide, calcium oxide will gradually become a functional filler for the purpose of reinforcement or imparting functionality.
Calcium oxide is widely used in filling resins such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene copolymer (ABS) and the like, has a certain effect of improving certain properties of plastic products to expand the application range of the plastic products, and can reduce the shrinkage rate of the resin, improve flow deformation and control viscosity in plastic processing.
The following effects can be achieved:
1. the addition of calcium oxide for improving the dimensional stability of the plastic products plays a role of a skeleton in the plastic products and has a great effect on the dimensional stability of the plastic products.
2. In plastics, especially soft polyvinyl chloride, the hardness of the plastic product is gradually increased along with the addition of calcium oxide, the elongation is reduced along with the increase of the hardness, the particle size is small, the oil absorption value of the calcium oxide is large, the hardness increase rate is large, and conversely, the particle size is coarse, the oil absorption value of the calcium oxide is small, and the hardness increase rate of the plastic is small.
In soft polyvinyl chloride, the hardness growth rate of heavy calcium oxide is the smallest, and precipitated calcium oxide (light) is the second.
Calcium oxide generally cannot play a reinforcing role in plastics, and particles of calcium oxide can be often soaked by resin, so the normal function of calcium oxide addition is to increase the rigidity of the resin, increase the elastic modulus and the hardness, and as the addition amount is increased, the tensile strength and the ultimate elongation are reduced, and different calcium oxides are added in different amounts, and the hardness is different.
3. The rheological property of the plastic can be changed by adding the calcium oxide for improving the processing property of the plastic, and the calcium oxide powder is often in a larger amount in the addition, so that the calcium oxide powder is beneficial to mixing with other components and processing and forming of the plastic.
The addition of calcium oxide, especially after surface treatment, can not only improve the hardness of the product, but also improve the surface gloss and surface smoothness of the product.
The addition of calcium oxide can reduce the shrinkage, linear expansion coefficient and creep property of the plastic product, and creates conditions for processing and forming.
4. The heat resistance of the plastic product is improved by adding calcium oxide into the common plastic product, and the heat resistance is improved, for example: about 40% of calcium oxide is added to polypropylene, and the heat resistance is improved by about 200 ℃. When the filling ratio is less than or equal to 20 percent, the heat-resistant temperature is improved by 8 to 130 ℃.
5. The light scattering property of the plastic is improved, in the plastic products, the products are required to be whitened and not transparent, the light extinction is desired, and the addition of the calcium oxide can play a certain role in the aspect.
The calcium oxide with the whiteness of more than 90 has obvious whitening effect in plastic products, and the extinction property of the plastic products is greatly improved by matching with titanium dioxide and lithopone.
In the calcium plastic paper, calcium oxide is added into Low Density Polyethylene (LDPE) and High Density Polyethylene (HDPE) films to achieve the functions of light scattering and extinction, so that the paper is suitable for writing and printing.
6. The product has certain special performance, the calcium oxide has certain insulating effect when added into the cable material, and the addition of the calcium oxide can improve the electroplating performance and the printing performance of certain products.
The superfine or superfine calcium oxide is added into polyvinyl chloride (PVC) to have a certain flame-retardant effect.
7. The price of common light calcium oxide and heavy calcium oxide for reducing the cost of plastic products is far lower than that of the plastic products, and the cost of the plastic products can be reduced by adding the calcium oxide.
In view of the above, research and improvement are made for the existing problems, and a preparation method and a method for adding calcium oxide to color master batches are provided, aiming at achieving the purposes of solving the problems and improving the practical value through the technology.

FIG. 1 is a schematic diagram of a manufacturing process of the present invention;
detailed description of the preferred embodiments
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The invention provides a specific technical implementation scheme of a preparation method of color master batch added with calcium oxide, which comprises the following steps:
the preparation method of the color master batch added with calcium oxide comprises the following steps:
filler agent: 60% -80%, coupling agent: 1% -3%, dispersant: 2% -5%, mixing layer: 15% -30%;
according to the above proportioning table, the following embodiments can be made:
the first embodiment is as follows: adding 60% of calcium oxide into a high-speed mixer, adding 30% of any one of APP, LDPE, HDPE, LLDPE, PS, CPE and EVA resin raw materials or any two blend carrier resin raw materials, adding 3% of coupling agent which can be any one of titanate silane, phosphate ester, borate, aluminate and the like during the mixing of the materials, adding 2% of cross-linking agent and diluent in total, simultaneously adding 5% of stearic acid, stearate, low molecular weight polyethylene, low molecular weight polystyrene and other low molecular weight polymers, mixing and homogenizing through a high-speed mixer, putting the mixed powder material into an extruder, extruding the powder material into a strip material, carrying out water cooling (drying treatment after water cooling) or air cooling, then carrying out cutting processing, and carrying out cylindrical or square granule processing on the processed master batch, and then carrying out screening, bagging and warehousing.
Example two: adding 60% of calcium oxide and 30% of AMS resin into a high-speed mixer, sequentially adding 3% of coupling agent, 2% of cross-linking agent, diluent and 5% of dispersing agent (see the mixture ratio materials in the first example) during mixing, melting, kneading and molding, cooling after kneading and molding, and preparing the mixture into granules or powder for later use by using crushing equipment;
when in use, the granules or powder are put into an extrusion device to be extruded into strip materials, the strip materials are cut into granules after water cooling (drying treatment after water cooling) or air cooling, the processed master batches are cylindrical or square granules, and the granules are bagged and warehoused after screening.
Example three: taking 60-80% of filler, adding 15-30% of any two or more blend carrier resin (waste resin or waste plastic) raw materials into a mixing layer, mixing, adding 1-3% of coupling agent, 2% of cross-linking agent, diluent and 2-5% of dispersing agent for smelting, and preparing into granules through extrusion equipment and a cutting device.
The master batch size of the granular material is as follows: 3 × 4mm, density of 1.7g/3cm, water content of less than 0.25%, and melt flow rate of 0.5-10 g/10min.
Specifically, the coupling agent is coated by titanate or silane or phosphate or borate or aluminate, and when the coupling agent acts on the surface of calcium oxide, calcium ions and carbonate ions on the surface of calcium oxide particles are contacted with water molecules in the atmosphere and hydrolyzed to generate an alkaline and oleophobic hydroxyl surface.
The surface hydroxyl groups of the calcium oxide can chemically bond with the inorganic-philic end of the aluminate coupling agent to produce surface-modified calcium oxide particles. The surface modified calcium oxide particles are blended with resin, the hydrophilic end of the coupling agent molecule can be entangled with the molecule of the resin, and the calcium oxide has an activating function due to the action of the coupling agent, so that the affinity of the calcium oxide with the organic resin is improved, and the resin is modified and enhanced.
Meanwhile, a proper amount of cross-linking agent and diluent are added for synergistic treatment, so that the binding force between the filler and the resin can be improved.
Specifically, the dispersing agent is stearic acid or stearate or low molecular weight polyethylene or low molecular weight polystyrene and other low molecular weight polymers, and because the molecular weight of the dispersing agent is low and the polymers are easy to melt during mixing, calcium oxide activated by a coupling agent can be used and then is treated by the dispersing agent to be better melted and dispersed in resin, so that a filled product with better appearance quality can be obtained, the calcium oxide treated by the dispersing agent is closer to matrix resin in the aspect of solubility parameter, the surface tension is similar to the matrix resin, the viscosity of the composite material is reduced, and the fluidity is improved.
In conclusion: the preparation method of the color master batch added with calcium oxide can reduce cost, improve hardness, elastic modulus, dimensional stability and thermal stability of products, obtain a reinforcing effect in products such as plastics, rubber and the like, and solve the problems in the preparation of the existing master batch.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
