Preparation method of formaldehyde removing impact bar of elevator car door

Abstract

The invention discloses a preparation method of a formaldehyde removing impact bar of an elevator car door and relates to the field of correlation technique of elevator materials. The formaldehyde removing impact bar of the elevator car door is prepared from the following components: easy processing channel black, foaming control agent DLF, vaseline, light calcium carbonate, antimony(III) oxide, zinc carbonate, stearic acid, salicylic acid, argil, aloe gel, diatom ooze, activated carbon, nano-modified alkyd resin, impact modifier ACM, polyethylene wax, stearic acid, antiager, butadiene-vinyl pyridine rubber, accelerator TMTM, N-cyclohexyl-2-benzothiazolesulfenamide and N-phenyl-1-naphthylamine. The formaldehyde removing impact bar of the elevator car door is efficiently resistant to impact, environmentally friendly, highly resistant to heat, tough, resistant to fatigue, weather, hot water and erosion of alkalis, acids, oils and halogenated hydrocarbon, self-lubricating, low in frictioncoefficient and highly resistant to hydrolysis, removes formaldehyde and has high practical value.

Description

Technical field: [0001] The invention relates to the related technical field of elevator materials, in particular to a preparation method of a formaldehyde-removing buffer strip for an elevator car door. Background technique: [0002] One of the elevator structures, that is, in the elevator, the elevator closes the door seen inside. It is opposite to the hall door (or landing door), that is, the door seen when calling outside. Elevators are vertical elevators, equipped with box-like gondolas, called cars, which are box-shaped spaces for elevators to carry and transport people and materials. The car is generally composed of main components such as the car floor, car wall, car roof, and car door. [0003] When taking an elevator in daily life, it is often encountered that when the elevator car door is closed, there will be noises caused by the car door closing. The gap between the car door leaf and the car decoration cabinet is too small, causing the door leaf and the door ...

AI Technical Summary

Problems solved by technology

The gap between the car door leaf and the car decoration cabinet is too small, causing the door leaf and the door cabinet to rub against each other; the safety touch panel of the car door is not adjusted in place, causing the two touch panels to collide and produce a collision sound; impact sound

[0004] Moreover, for new buildings or newly decorated elevators, there will be formaldehyde. People often travel in elevators, and the existence of formaldehyde is harmful to people's health.
