Abstract

The invention discloses a Teflon coating material and an application thereof. The Teflon coating material comprises a top coat and a primer, wherein the top coat comprises the following components inparts by weigh: 100 parts of polytetrafluoroethylene dispersion solutions, 1-5 parts of mica powder, 15-25 parts of mixed solutions, 0.1-1 part of metal oxide, 5-15 parts of binary thermoplastic copolymer dispersion solutions and 0.5-1 part of a nonionic surfactant; the primer comprises the following components in parts by weigh: 100 parts of polytetrafluoroethylene dispersion solutions, 5-10 parts of mica powder, 1-5 parts of graphite powder, 1-5 parts of metal oxide, 5-10 parts of polyphenylene sulfide, 20-40 parts of polyamic acid salt solutions, 20-40 parts of silica sol and 80-120 parts of deionized water. According to the Teflon coating material prepared by a composition, smooth, corrugated and burr-free extruded pipe products can be ensured, and the time for the coating material tocompletely adhere to the metal surface of an extrusion die is prolonged, and thus the replacement time of the extrusion die is prolonged, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to the field of chemical industry, in particular to a Teflon coating and its application. Background technique

[0002] As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, sanitation, environmental protection, and low consumption. Among them, the strong development momentum of PE pipes is the most eye-catching. Polyethylene pipes are used in a wide range of fields, among which water supply pipes and gas pipes are the two largest application markets.

[0003] The polyethylene pipe production line includes extrusion host, pipe die shaping device, shaping die, cooling device, traction device, cutting device, collecting device and other parts. In pipe extrusion production, the surface finish, solid lubrication and friction coefficient of the extruder die and corner head will directly affect the performance and quality of the pipe product. At present, the ge...
