Problems solved by technology

[0004] In the prior art, in the process of preparing modified plastic particles, the modified plastic particles need to be dried, but in the actual use process, due to the adhesion of modified plastic particles to each other through water, it is easy to occur drying. Inhomogeneity may cause part of the modified plastic particles to be damaged due to excessive local temperature

Embodiment 1

[0041] see figure 1 , a preparation process of modified plastic particles, comprising the following steps:

[0042] S1. Put antistatic agent, antiaging agent, release agent, toughening agent, glass fiber, silicone powder, sodium carboxymethyl cellulose, and talc into the mixer for low-speed mixing, mix for 3-8 minutes and add ASA Rubber powder, then mix at high speed for 5-10 minutes;

[0043] S2. Transport the mixed material to the twin-screw extruder through the pipeline for shearing, plasticizing and extruding, and use the water circulation cooling system to water-cool the strips. The water-cooling temperature is 30-39°C, and the obtained plastic strips are transported to the traction pelletizer. , the speed of the granulator is 600-900rpm, thus forming wet plastic particles;

[0044] S3. Add wet plastic particles into the drying cylinder, add auxiliary drying balls 1 inside, and rotate the drying cylinder while heating the drying cylinder, so as to complete the drying of...

Abstract

The invention discloses a preparation process of modified plastic particles, and belongs to the technical field of plastic production. According to the scheme, the preparation process of the modifiedplastic particles that potassium permanganate powder in a built-in storage bag can be promoted to be heated and gradually decomposed by continuously heating the modified plastic particles and auxiliary drying balls in a drying box, a large amount of oxygen is generated, so that the expansion of a convex capsule sleeve is realized, the oxygen ejects a rubber sealing sheet and then is diffused fromrelease through holes to promote a protective film to be opened, so that the contact efficiency of the protective film and moisture in the modified plastic particles is improved, after the protectivefilm is dissolved, on one hand, by means of release of oxygen, the plastic particles in a drying cylinder can be scattered, and the drying efficiency of the plastic particles is improved, and on the other hand, a large amount of heat can be generated by means of the reaction of oxygen and the reductive iron powder in the protective film, so that the drying effect on the modified plastic particlesis further improved.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to a preparation process of modified plastic particles. Background technique [0002] Plastic is a polymer compound (macromolecules) that is polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It has medium resistance to deformation and is between fiber and rubber. Composed of additives such as additives, lubricants, and colorants. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipid secreted by animals and plants. Such as rosin, shellac, etc., resins account for about 40% to 100% of the total weight of plastics. The basic properties of plastics are mainly determined by the nature of resins, but additives also play an important role. Some plastics are basically composed of synthetic resins. Containing no o...
