preparation example Construction

[0067] The preparation method of insect-proof masterbatch 1-14 is:

[0068] Take polypropylene resin, modified silica, antioxidant, lubricant and weather-resistant agent in proportion and mix them evenly, then add them to a twin-screw extruder for extrusion and granulation; wherein, the molding temperature of the extruder is set At 130 to 150°C, the rotational speed range is set to 200 to 400 rpm.

[0069] Wherein, the preparation method of modified silica is:

[0070] The porous silica powder, repellent, synergist, and anhydrous alcohol are placed in a water bath at 70-80° C., and the product is prepared by stirring, filtering, washing and drying.

[0071] The components of insect-proof masterbatch 1-14 are shown in Table 1.

Embodiment 1～7 and comparative example 1～8

[0076] The preparation methods of the insect-proof polypropylene compositions of Examples 1-7 and Comparative Examples 1-8 are:

[0077] The polypropylene resin and the insect-proof masterbatch are mixed uniformly in proportion, and then added to a twin-screw extruder for extrusion and granulation; wherein, the molding temperature of the extruder is set at 130~180℃, and the rotational speed range is set at 200~ 400 rpm.

[0081]

[0082]

[0083] It can be seen that the insect-proof polypropylene compositions of Examples 1 to 7 have good light diffusion, high repelling rate, good repelling rate after thermal aging and photoaging, and can effectively prevent the volatilization of repellants during high-temperature aging. Avoida...

Abstract

The invention belongs to the technical field of high polymer materials, and discloses an insect-proof master batch, a polypropylene composition thereof and a preparation method of the insect-proof master batch. The insect-proof master batch is prepared from the following components in parts by weight: 60 to 75 parts of polypropylene carrier resin, 15 to 25 parts of modified silicon dioxide, 0 to 0.6 part of antioxidant, 0 to 0.5 part of lubricant and 6 to 10 parts of weather-proof agent. When the insect-proof polypropylene composition is prepared, volatilization and decomposition of a repellent in the processing process of an extruder can be effectively reduced, rapid volatilization of the repellent is prevented, and durability of the insect-proof effect is guaranteed; the light diffusion effect, the insect prevention effect and the irradiation resistance are good, and the lamp can be widely applied to the field of illumination.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an insect-proof masterbatch, a polypropylene composition thereof and a preparation method thereof. Background technique [0002] Mosquitoes like to chase the light source, especially the street lamps on the roadside in summer. Mosquitoes gather on the lampshade, which affects the lighting effect of the lampshade over time, and even the dead mosquitoes adhere to the lamps, which may cause a short circuit for a long time. At present, the existing conventional improvement scheme is generally to add insect repellents, such as Chinese invention patent document CN20191068741.7 A kind of light diffusing polypropylene material that can repel insects and its preparation method, by adding permethrin, pyrethrin One or more repellents among esters, permethrin, and deltamethrin are used to achieve the insect control effect, but there are dozens of types of pyrethroids, and the level...
