Problems solved by technology

At present, domestic fiberglass hoses are generally produced by heating and baking solvent-based insulating varnishes. The disadvantages are "two highs and one low", that is, high energy consumption, high pollution, and low efficiency.
The solid content of the formula in the traditional process is about 40-60%, and about 50% of the solvent needs to be added. The added solvent is only used to reduce the viscosity of the system, and does not participate in film formation; traditional solvent-based coatings are due to viscosity, solid content, and curing efficiency. Generally, 2-3 layers need to be coated to achieve high electrical insulation, which is not only complicated to operate, long in time, but also high in production cost.

Abstract

The invention discloses a method for preparing a glass fiber insulating flexible pipe through photocuring, relating to the technical field of glass fiber insulating flexible pipes. The method comprises the following steps: (S1) selecting a glass fiber tube blank, and carrying out round formation by virtue of a blank rounding machine, so as to form a glass fiber flexible pipe; (S2) selecting 70-80 parts of UV resin, 15-20 parts of an active diluent, 4-7 parts of an initiator and 1-3 parts of an aid; and (S3) coating the glass fiber tube blank obtained in the step (S1) with a solvent type coating prepared in the step (S2), curing the solvent type coating by virtue of an ultraviolet lamp to form an insulating layer and produce a glass fiber insulating flexible pipe finished product, and carrying out detection and warehousing. By carrying out irradiation curing on the solvent type coating on the glass fiber flexible pipe by virtue of the ultraviolet lamp, the method has the characteristics of short curing time, low processing cost, high production efficiency and good insulating quality.

Description

technical field [0001] The invention relates to the technical field of glass fiber insulating hose production, in particular to a method for preparing a glass fiber insulating hose by light curing. Background technique [0002] Fiberglass insulation hose is an electrical insulation product, mainly used in the electrical and electrical industry, and is sheathed on the outside of the wire joint for insulation protection. At present, domestic fiberglass hoses are generally produced by the method of heating and baking solvent-based insulating varnishes. The disadvantages are "two highs and one low", that is, high energy consumption, high pollution and low efficiency. The solid content in the formula of the traditional process is about 40-60%, and about 50% of the solvent needs to be added. The added solvent is only used to reduce the viscosity of the system and does not participate in film formation; traditional solvent-based coatings are due to viscosity, solid content, and cur...
