Abstract
The invention discloses a new material specially applied to transparent plastics, the components of the material is as follows by weight percent: 75-80 percent of transparent powder, 8-10 percent of dispersing agent, 0.003-0.01 percent of auxiliary agent, 1-2 percent of coupling agent and 15.997-7.99 percent of carrier resin. The method for preparing the new material includes the following steps: firstly, each component is weighed accurately by weight percent; then, the transparent powder is placed in a high-speed mixer for high-speed blending and drying, the coupling agent is added for activation processing, and the dispersing agent, carrier resin and auxiliary agent are added, and the mixture is placed in a kneading pot (current control: 30-50A) and mixed at high speed, kneaded to the extent that the transparent powder is completely coated, and discharged for standby use after being humidified; finally, the kneaded materials are injected into a parallel double screw extruder (the temperature of the host machine is controlled at 100-160 DEG C) and extruded out, then hot-cut and wind-cooled to achieve the desired masterbatch, and then checked, packaged and stored in the warehouse. The plastic products made of the new material have the advantages of sound transparency, good dispersion, large quantity of addition, low cost, and the like.
Description
Technical field
The present invention relates to the preparation field of plastics, especially a kind of novel material that is exclusively used in transparent plastics and preparation method thereof
Background technology
Along with constantly riseing of world market oil price, the plastic raw materials price also skyrockets.In face of the operated pressure that strengthens suddenly, plastic industry need take effective measures dissolves cost pressure, is the best approach that reduces cost and add stopping composition.General stopping composition influence the transparency of sack, and product does not improve grade, and therefore studies the novel material that does not influence quality and transparency and can reduce cost, and is most important for the development of plastic industry.
Summary of the invention
Purpose of the present invention be exactly overcome the deficiency that prior art exists and provide a kind of to the transparency influence little can reduce production costs be exclusively used in novel material of transparent plastics and preparation method thereof.
For achieving the above object, technical scheme of the present invention is as follows:
This weight percent that is exclusively used in each component of novel material of transparent plastics is: transparent powder 75-80%, dispersion agent 8-10%, auxiliary agent 0.003-0.01%, coupling agent 1-2%, vector resin 15.997-7.99%.
Described transparent powder is that silicon-dioxide is the non-metallic minerals of main component, and pure product are transparent like hyaloid, Mohs' hardness is 5-6, is processed into the fine powder that 1250 order particle diameters are not more than 10 μ m, is little yellow, approaching with color of resin, transparent high again whiteness, it is higher to contain moisture.
Described dispersion agent comprises polyethylene wax, paraffin, stearic acid, Zinic stearas, wherein:
The polyethylene wax relative molecular weight is at 1500-9500, relative density 0.9-0.93g/cm
3, softening temperature 101-115 ℃, few from usage quantity, that dispersion effect is good angle is considered to select for use the narrow kind of molecular weight for well;
Paraffin is white solid, density 0.87-0.92g/cm
3, fusing point 57-63 ℃, add the flowability that paraffin can improve system, help improving the quality of products;
Stearic acid i.e. 18 hydroxy acids, are a kind of senior saturated hydroxy acid compounds, 70 ℃ of fusing points, 376 ℃ of boiling points, relative density 0.84g/cm
3, refractive index 1.4337 to select for use the low person of iodine number and iodine number for well, removes and also can be used as lubricant as dispersion agent;
The fusing point of Zinic stearas is 118-122 ℃.
Described auxiliary agent is a whitening agent, and outward appearance is the yellow-green colour crystalline powder, fusing point 353-357 ℃, can improve the whiteness of goods.
Described coupling agent is a kind of tensio-active agent, and its intramolecularly contains two classes structure gene of different nature, is used to handle transparent powder, can select wherein one or both of aluminate coupling agent, titanate coupling agent, boric acid ester coupler for use.
Described vector resin is one or both of linear low density polyethylene or new LDPE (film grade), and wherein the melt flow rate (MFR) of linear low density polyethylene is 1-2.5g/10min, and the melt flow rate (MFR) of new LDPE (film grade) is 7g/10min.
This preparation method of novel material who is exclusively used in transparent plastics is as follows: at first that the accurate weighing of each compositions in weight percentage is good standby, then transparent powder is placed high-speed mixer to carry out the high-speed mixing oven dry, add coupling agent and carry out activation treatment, add dispersion agent, vector resin, behind the auxiliary agent compound is placed in the kneading pot that current control is 30-50A and carries out high-speed mixing, mediate to transparent powder and coated fully, wetting back discharging is standby, to mediate material at last puts into the parallel double-screw extruder that the main frame temperature is controlled at 100-160 ℃ and extrudes, through fervent, air-cooledly make required masterbatch, check, the packing warehouse-in.
In sum, the plastics that adopt the novel material that is exclusively used in transparent plastics provided by the present invention to make have advantages such as transparency is good, scattered, addition is high, significantly reduce cost.
