Problems solved by technology
[0004] The invention provides a preparation process of modified plastics, which aims to solve the following problems in the preparation of modified plastics: (1) When the plastics are heated to a molten state, the plastics cannot be fully melted, resulting in mixing of the plastics in the molten state and the modifier After stirring, there are some plastic particles in the mixture, which will adversely affect the performance of the modified plastic; (2) the plastic in the molten state has poor fluidity, and the modifier cannot be fully and uniformly mixed with the plastic in the molten state, which will also cause Detrimental effect on properties of modified plastics

Embodiment Construction
[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0033] Such as figure 1 As shown, the present embodiment provides a modified plastic preparation process, comprising the following steps:
[0034] Step 1. Cutting and melting: Cut the plastic block into small pieces of uniform size, and then heat the small plastic block into a molten state.
[0035] Step 2, mixing and stirring: Add the modifier to the molten plastic prepared in step 1, and stir the mixture evenly.
[0036] Step 3, cooling and shaping: Extrude the molten mixture prepared in Step 2 through an extruder, and then cool and shape it.
[0037] Wherein, the process of stirring the mixture uniformly described in step 2 adopts such as Figure 2 to Figure 5 A modified plastic preparation machine shown in the figure is completed by cooperati...

The invention belongs to the technical field of plastic manufacturing, and specifically relates to a preparation process of modified plastics, comprising the following steps: Step 1, cutting and melting: cutting the plastic block into small pieces of uniform size, and then heating the small plastic block into a molten state; step 2. Mixing and stirring: Add the modifier to the molten plastic prepared in step 1, and stir the mixture evenly; Yes; wherein, the process of stirring the mixture uniformly in step 2 is completed by using a modified plastic preparation machine. The invention eliminates the plastic particles in the plastic in the molten state, improves the mixing uniformity of the plastic in the molten state and the modifying agent, thereby improving the performance of the modified plastic.
Description
technical field [0001] The invention belongs to the technical field of plastic manufacturing, and in particular relates to a preparation process of modified plastic. Background technique [0002] Modified plastics refer to plastic products that are processed and modified on the basis of general-purpose plastics by methods such as filling, blending, and reinforcement, and have improved properties such as flame retardancy, strength, impact resistance, and toughness. When preparing modified plastics, it is necessary to first heat the plastic raw materials into a molten state, then add modifiers to the molten plastics, mix and stir them into a mixture, and finally extrude the mixture to shape and cool. At present, there are the following problems in the preparation process of modified plastics: (1) When the plastics are heated to a molten state, the plastics cannot be fully melted, resulting in the mixing and stirring of the plastics in the molten state and the modifier, and the...
