Description
Technical Field
The invention relates to the field of materials, in particular to an anti-aging color master batch and a preparation method thereof.
Background
The color master batch is a novel high-molecular composite coloring material prepared by well dispersing a colorant, a carrier resin and various auxiliary agents with high proportion. The colorant is the basic component of the color master batch, and the content is generally between 20 and 80 percent. The white master batch usually adopts titanium dioxide, barium sulfate, lithopone, zinc sulfide, calcium carbonate and the like as coloring agents, the black master batch adopts carbon black as a coloring agent, and the color master batch adopts azo pigment, phthalocyanine pigment, quinacridone pigment, iron oxide red, metal powder, pearl powder, dye and the like as coloring agents. The resin is a carrier of the color master batch, has the properties of softening by heating and hardening by cooling, and has the characteristics of no chemical reaction and the like. The resin is subjected to processes such as melting and shearing, so that the colorant is uniformly distributed in the resin. In order to ensure the compatibility of the carrier with the plastic to be colored, the same resin as the plastic to be colored is generally selected as the carrier, which facilitates better dispersion of the colorant. The dispersing agent belongs to an auxiliary agent and can promote the coloring agent to be uniformly dispersed in the resin and not to be agglomerated. The dispersing agent commonly used at present is polyethylene low molecular wax, stearate, glycol and the like. According to the requirements of the application and performance of the product, other various auxiliary agents such as antistatic agent, antioxidant, brightener, light stabilizer, foaming agent, antibacterial agent, delustering agent, flame retardant and the like are added in the preparation process of the color master batch, so that the plastic product is endowed with special functions.
The color master batch is more and more widely applied in industrial production, and people have higher and higher requirements on the functionality of the color master batch. Environmental pressures and new demands for downstream synthetic resins are driving technological advances in the color masterbatch industry. The color master batch industry mainly using small-scale enterprises must adopt a research and development mode of enterprise union and industrial chain cooperation, improve the production process, promote the clean production level, and develop a new process and a new formula aiming at the new requirements of downstream high-quality plastic and chemical fiber products.
The Chinese patent with the publication number of CN201410805410.3 discloses a special anti-aging dimming red master batch for solanaceous vegetable greenhouse films and a preparation method thereof, and discloses a special anti-aging dimming red master batch for solanaceous vegetable greenhouse films and a preparation method thereof.
However, although the color master batches of the prior art are also proposed to have the function of preventing aging, the color master batches of the prior art have insignificant anti-aging effect and cannot resist long-term corrosion in severe environments.
Disclosure of Invention
Aiming at the technical problems, the invention provides a color master batch with high efficiency and long-term aging resistance and a preparation method thereof.
The invention provides an anti-aging color master batch, which comprises the following main components in parts by weight: 7-12.5 parts of light stabilizer, 2-3 parts of ultraviolet absorbent, 2.5-5 parts of antioxidant, 4.5-5.5 parts of titanium dioxide, 0.1-0.2 part of carbon black, 4-6 parts of dispersant and 70-80 parts of low density polyethylene.
Preferably, the weight ratio of the light stabilizer to the ultraviolet absorber to the antioxidant is 3-4: 0.9-1.1: 1.48-1.6.
Preferably, the light stabilizer comprises one or a combination of two of basf 2020 and basf 5050.
Preferably, the ultraviolet absorber comprises one or a combination of basf UV326, basf B75.
Preferably, the antioxidant comprises one or a combination of two of basf B215, B911.
Preferably, the dispersant is an EVA wax.
Through long-term research and a large number of tests, the color master batch can resist severe environment for a long time, and the analysis reason is probably due to the blocking of light stabilizer, ultraviolet absorbent, antioxidant and carbon black in the color master batch formula on ultraviolet and the absorption or blocking of light and gas for promoting aging. Meanwhile, the EVA wax serving as a dispersing agent is added into the formula of the invention, so that the EVA wax has a good effect on the dispersion of the carbon black and further promotes the function of the carbon black for absorbing ultraviolet rays.
In another aspect of the invention, a preparation method of the anti-aging color master batch is provided, which comprises the following steps:
1) proportioning the raw materials according to the weight portion of the color master batch provided by the invention;
2) putting the raw materials proportioned in the step 1) into a uniform stirrer for stirring at the stirring temperature of 60-100 ℃ for 4-8 min;
3) putting the uniformly stirred mixture obtained in the step 2) into a double-screw extruder for melt blending granulation.
Preferably, the twin-screw extruder has 11 sections, and the temperature ranges of the sections are respectively as follows: 145-155 ℃, 155-165 ℃, 160-170 ℃, 165-175 ℃, 160-170 ℃ and 160-170 ℃.
Because the formula of the color master batch is greatly different from the prior art, the manufacturing process of the color master batch is greatly improved, particularly the traditional double-screw extruder is changed from 3-7 sections to 11 sections, and the corresponding temperature of each section is also changed from the traditional 3-7 section temperature to 11 sections. The reason for the analysis is probably that the formula and the proportion of the color master batch are changed, so that more time is needed in the double-screw extrusion process and the qualified rate of the color master batch is ensured by more temperature gradients.
Compared with the prior art, the technical scheme of the invention has the following advantages: the invention provides a formula and a proportion of a novel color master batch, the color master batch has the advantages of stronger and long-term adverse environment resistance, and the invention also provides a manufacturing method of the color master batch.
