[0002] Plastic materials have become the most important materials in people's daily life, such as plastic bags, plastic cups, shells of most home appliances, shoe materials, tableware, raincoats, agricultural films, packaging films, containers, stationery, sports products, Household items are all plastic products, so plastic materials are inseparable from people's daily life. However, existing plastic products will be weathered and faded after being exposed to sunlight and oxygen. The plastic products are easily broken, and the colors and patterns on them fade and affect the appearance; and in order to prevent the above problems, the present invention prepares a plastic additive that can delay weathering and fading, which can effectively resist under high temperature. The plastic is oxidized and at the same time delays the fading of the plastic

Embodiment Construction
[0025] The specific process steps are: Step 1: Antioxidant TNP is cooled to -5°C to solidify, and then ground into powder to obtain antioxidant TNP powder; Step 2: Antioxidant TNP powder and antioxidant MB powder are dissolved in acetone solution, and stirred; Step 3: After stirring evenly, a mixed solution is obtained; Step 4: Heat the mixed solution to volatilize the excess acetone solution in the mixed solution to obtain a gel-like additive, and in Step 2, the antioxidant TNP powder is mixed with The volume ratio of antioxidant MB powder is 3 to 1. According to the experiment, after mixing in this ratio, the performance of the additive obtained is the best.
[0026] see Figure 2 to Figure 4 , according to what can be obtained as shown in the figure, an exemplary working process of solidifying the antioxidant TNP into a solid state is:
[0027] The antioxidant TNP is a light yellow viscous liquid under normal conditions, and the antioxidant MB is a light yellow powder, so ...

Abstract
The invention relates to the technical field of plastic additives, in particular to a plastic additive and a preparation process thereof. The plastic additive can prevent plastic from being oxidized under high temperature, and meanwhile, can delay the color fading of plastic. The process comprises the following steps of: 1, cooling an antioxidant TNP to -5 DEG C for solidification, and then grinding the antioxidant into powder to obtain antioxidant TNP powder; 2, dissolving the antioxidant TNP powder and antioxidant MB powder in an acetone solution, and stirring; 3, stirring well to obtain a mixed solution; and 4, heating the mixed solution to volatilize the redundant acetone solution in the mixed solution to obtain a gelatinous additive. A plastic additive preparation device is used and comprises a volume barrel, a pressing plate, a refrigerating coil and a blocking plate, wherein the pressing plate can slide along the axis of the volume barrel, the refrigerating coil is arranged on the outer wall of the volume barrel, and the blocking plate can cover the volume barrel.
