Description
Technical Field
The invention belongs to the technical field of garbage can processing, and particularly relates to a garbage can processing technology.
Background
Extrusion granulation is a crucial ring in the injection molding of the garbage can, and the existing extrusion granulator mostly adopts a cold cutting type in order to realize the uniformity of granules, but has larger floor area and sharp granular edges; the size of the granules of the die opening hot cutting type is not easy to control, the specification of each machine is fixed, and equipment needs to be replaced when the diameter of the granules changes, so that the limitation is large.
Disclosure of Invention
The invention provides a garbage can processing technology which is uniform in particle shape and capable of processing garbage cans with multiple diameters in order to overcome the defects of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: a garbage can processing technology comprises the following steps
(1) Heating and softening polyvinyl chloride, adding polyvinylidene fluoride, acrylonitrile-butadiene-styrene copolymer and liquid paraffin, mixing, and carrying out ultrasonic oscillation homogenization in an ultrasonic oscillator, wherein the homogenized liquid is reserved;
(2) limiting, mixing and adjusting the pH value of the organic silicon resin, the alkyd resin and the basalt to 7.8-8.0, and then mechanically modifying the mixture in a stirrer by high-speed stirring to obtain mixed resin for later use;
(3) mixing hexamethylphosphoric triamide, zinc oxide, silicon dioxide and a flame retardant, heating and stirring, adding the homogeneous liquid, and performing ultrasonic oscillation homogenization again to obtain a mixed liquid for later use;
(4) adding phenoxyethanol, 1, 2, 3-benzotriazole and a plasticizer into the mixed solution, and uniformly stirring at the high temperature of 120-130 ℃ to obtain a mixed material for later use;
(5) and adding the mixed resin and the mixed material into octamethylcyclotetrasiloxane and antioxidant, mixing, adding into a screw extruder, extruding and granulating, then carrying out injection molding on the obtained master batch, and processing and assembling to obtain the antioxidant cold-resistant environment-friendly trash can.
