Abstract

The invention discloses a preparation technology of an escalator component. Diethylenetriamine, tetraethylenepentamine, limestone, a deelectric agent, an anti-aging agent, and tributyl phosphate are added in polyvinyl chloride and are uniformly stirred by a stirring machine, and a mixture is obtained after stirring; the obtained mixture is positioned in a mixing mill for mixing, when mixing is started, a reinforcing agent is added to the mixture in the mixing mill synchronously at uniform speed, wherein the reinforcing agent needs to be completely positioned in within 200 seconds, and the whole mixing time is 900-2400 seconds, and a block body is obtained after mixing; and the obtained block body is compressed into a piece by a calander, and is in still standing for 36 hours at 25-28 DEG Cto obtain thermoplastic resin. The technology effectively avoids the defects in the prior art that a box body of a server crate is commonly positioned on the ground vertically, and therefore positioning is not firm, tensile modulus of elasticity and bending modulus of elasticity are insufficient, and higher requirements of the tensile modulus of elasticity and bending modulus of elasticity can not be met.

Description

technical field [0001] The invention relates to the technical field of handrail component manufacturing, in particular to a manufacturing process of an escalator component. Background technique [0002] The escalator handrail is a special-shaped molded product made of a composite material in which a metal steel wire is arranged inside a thermoplastic resin. For added strength, escalator handrails sometimes use a metallic steel wire consisting of a central strand (plain wire) and multiple strands. A metal steel wire used to form a composite material is composed of a central strand and a plurality of strands. In the case of twisting the central strand and the plurality of strands in the prior art, there are problems such as the following: The thermoplastic resin cannot be evenly filled between the strands and the strands, and the pull-out strength of the metal steel wire to the thermoplastic resin material fluctuates greatly, and sometimes the desired pull-out strength cannot...
