Abstract

The invention relates to a production device for an outer protective layer sheet. The production device comprises a base; a base material feeding mechanism, a glass fiber feeding mechanism and a rolling mechanism are arranged on the base; a take-up mechanism is arranged at one side of the base; the base material feeding mechanism is used for separately forming an outer epoxy vinyl ester base layer and an inner epoxy vinyl ester base layer on an upper bearing film and a lower bearing film; the glass fiber feeding mechanism is used for adding a glass fiber reinforcing layer and a glass fiber loop bonding felt between the outer epoxy vinyl ester base layer and the inner epoxy vinyl ester base layer; the rolling mechanism is used for pressing and forming the upper bearing film, the outer epoxy vinyl ester base layer, the glass fiber reinforcing layer, the glass fiber loop bonding felt, the inner epoxy vinyl base layer and the lower bearing film; and the take-up mechanism is used for collecting and rolling a pressed and formed outer protective sheet. The production device is automatic in operation, improves working efficiency and product quality, and improves flatness of products.

Description

technical field

[0001] The invention relates to a production device, in particular to a production device for an outer protective layer sheet. Background technique

[0002] Pipeline crossing project is a pipeline project in which transportation pipelines are laid underwater or underground through rivers, lakes, railways, highways and other areas.

[0003] Pipelines are easily corroded in underwater or underground environments, and are generally protected by coating anti-corrosion coatings. However, this method has a short protection period and still poses safety hazards when used for a long time.

[0004] The applicant has developed a six-layer structure of the outer protective layer sheet, the sheet from bottom to top is "upper bearing film, outer epoxy vinyl ester base layer, glass fiber reinforced layer, glass fiber stitched mat , Inner epoxy vinyl ester base layer and lower bearing film", this kind of sheet has light weight, high tensile strength and weather resistance,...
