Abstract

The invention discloses a method for preparing a non-cracking sanitation trash can, which comprises the following steps: mixing polyurethane and vermiculite powder, grinding, then raising the temperature, stirring, adding triallyl isocyanurate to continue stirring, and stirring under nitrogen protection Heat up, stir, cool, pulverize, add acrylonitrile-butadiene-styrene copolymer, polyaryl sulfone and mix evenly to obtain premix a; mix bamboo fiber, mica powder, carbon nanotubes, sepiolite powder, boric acid Calcium, pine tar, triglyceride, methyl silicone oil, microcrystalline paraffin, and stabilizer are uniformly mixed to obtain premix b; premix a and premix b are mixed, melt-extruded and granulated, and formed to obtain a non-cracking Sanitation trash can. The invention has simple process and low production cost, and the obtained sanitation garbage bin not only has extremely low apparent defects, but can effectively reduce its deformation, thereby effectively improving its aesthetics, and has excellent tensile strength and is not prone to stress cracking.

Description

technical field [0001] The invention relates to the technical field of garbage cans, in particular to an unbreakable sanitation garbage can. Background technique [0002] Sanitation trash cans bring cleanliness, sanitation and environmental protection to various public places. The sanitation garbage can is a common daily necessities, which is used to put garbage in the public environment. The existing garbage cans are generally composed of a cylindrical plastic cylinder. During use, the current sanitation trash cans are often cracked, making the public environment dirty and unhygienic to use. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a preparation method for a sanitation trash can that is not easily cracked, the process is simple, and the production cost is low. The resulting sanitation trash can not only has extremely low apparent defects, but can effectively reduce its deforma...
