Abstract

The invention discloses an anti-aging plastic particle and a preparation method thereof. The preparation method of the plastic particle comprises the following steps: preparing modified polystyrene, preparing modified polypropylene, preparing modified diatomite, and carrying out internal mixing on plastic particle raw materials to obtain the anti-aging plastic particle. According to the invention,polystyrene and polypropylene are respectively modified, an anti-aging solution and diatomite are mixed to obtain modified diatomite, and the modified diatomite is added into the preparation raw materials of plastic particles, so that the aging resistance of the plastic particles is greatly improved; and the anti-aging solution is absorbed by the diatomite with a porous structure, so that the anti-aging solution can be stably adsorbed on the diatomite, the durability of the anti-aging effect of the plastic particles is ensured, and the diatomite can be fully absorbed by grinding and refiningthe diatomite.

Description

technical field [0001] The invention relates to a plastic particle, in particular to an aging-resistant plastic particle and a preparation method thereof. Background technique [0002] Plastic has the characteristics of light weight, no rust, good insulation and so on, and is widely used in life. Plastic products can be seen everywhere in daily life, and their application fields are very wide, and all fields cannot be completely separated from plastic products; traditional plastic particles have poor aging resistance and poor durability of aging resistance. In the production process of traditional plastic particles, The processing steps are complicated and the production efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an aging-resistant plastic particle and a preparation method thereof. The present invention obtains modified diatomite by mixing the anti-aging solution and diatomite by modifying polystyrene and polypr...
