Description
Technical Field
The invention relates to a polypropylene composition for lamps and a preparation method thereof, belonging to the technical field of polypropylene modification.
Background
In the application fields of household illumination, advertising lamp boxes, decorative lamps, signs and the like, in order to convert point light sources or line light sources into lines and surface light sources, the light distribution is more uniform and soft, and people develop light scattering materials. Different from the properties of transparent materials, such as high light transmittance and low haze, light scattering materials have high light transmittance and high haze, i.e., light is allowed to pass through and be effectively scattered. Currently, most light diffusing materials are prepared by a blending process. The light-diffusing agent is generally prepared by using a transparent resin as a matrix, such as polymethyl methacrylate (PMMA), Polycarbonate (PC), and the like, and adding a light-diffusing agent to the matrix resin. The light diffusing agent is inorganic particles such as glass beads, silicon dioxide (SiO2) and the like; and organic polymer fine particles such as Polystyrene (PS), silicone resin, and the like. Although PMMA has good optical performance, the material has the defects of poor impact toughness, easy breakage, high specific gravity, difficult processing, high cost and the like.
Polypropylene is a general plastic with excellent comprehensive performance, and has been widely applied to the fields of automobiles, household appliances, daily necessities, pipelines, medical and electronic appliances and the like at present due to excellent mechanical properties, good electrical insulation, low density and relatively low price. In the prior art, the common method is to perform anti-reflection modification and rigidity-increasing modification on homo-polypropylene or random co-polypropylene, and add light diffusant and the like to obtain the polypropylene light scattering material.
The Chinese patent CN201210519772 discloses a light diffusion modified polypropylene material and a preparation method thereof, wherein a silicone light diffusion agent, a sorbitol transparent nucleating agent, an antioxidant and a light stabilizer are added into random copolymer polypropylene to change the performance of the polypropylene material and realize the light diffusion effect. The polypropylene modified material still has the problems of lower impact property and non-uniform light transmittance.
The invention Chinese patent CN201210045540 discloses an impact-resistant weather-resistant polypropylene material for lamps and a manufacturing method thereof, and the impact-resistant weather-resistant polypropylene material is prepared by adding 0-30% of impact-resistant master batch and 4-10% of weather-resistant coloring master batch into homo-polypropylene, wherein the impact-resistant master batch is prepared by adding activated inorganic powder into random copolymer polypropylene, and the weather-resistant coloring master batch is prepared by adding sorbitol or organic phosphate transparent nucleating agent and light diffusant auxiliary agent. The impact properties of the compositions are still not high and the preparation steps are complicated.
Chinese patent CN201710075138 discloses a polypropylene bulb material and a preparation method thereof, wherein a third-generation sorbitol transparent nucleating agent, an aryl carboxylic acid aluminum salt rigidity-increasing nucleating agent, an organic light diffusing agent, a fluorescent whitening agent, ethylene bis-stearamide, an antioxidant, an ultraviolet absorbent and the like are added into polypropylene. The impact properties of the resulting compositions are not high.
Chinese invention patent CN 101608035A discloses a preparation of hexagonal β crystal polypropylene material of structural nano material, which is characterized in that under the condition that β crystal nucleating agent and 4-10% calcium carbonate are added into homo-polypropylene (PPH) or random copolymerization polypropylene (PPR) with low melt mass flow rate (0.2-0.4g/10min), a polypropylene material with improved crystal form is obtained.
In the existing technical scheme for preparing the polypropylene light diffusion material, the prepared material has low impact property and complex components in the technical scheme, and the problems that the light diffusion agent is difficult to disperse and is unfavorable for light transmittance and impact property exist.
