Problems solved by technology

In the field of heavy anti-corrosion, the traditional construction technology adopts the construction technology of several coats and several cloths. The construction speed and efficiency are low. The factors affected by the construction conditions in the field or in harsh environments are relatively large, and the overall construction is also affected by the different proficiency of the construction personnel. Quality, traditional materials produce a large amount of harmful substances and flammable volatiles during the curing process, seriously affecting the environment and safety of construction personnel and construction projects, and waste will cause serious pollution

The ultraviolet curing sheet comprises an upper carrier film, an outer epoxy vinyl ester resin base layer, a short chopped glass fiber, a glass fiber mat, an inner epoxy vinyl ester resin base layer and a lower carrier film in turn from top to bottom, wherein the outer epoxy vinyl ester resin base layer and the inner epoxy vinyl ester resin base layer are composed of the following components: epoxy vinyl ester resin, unsaturated polyester resin, a ultraviolet curing agent A, a ultraviolet curing agent B, a padding impregnating compound, a glass fiber impregnating compound, a ultraviolet light stabilizer A, a ultraviolet light stabilizer B, aluminum hydroxide A, aluminum hydroxide B, magnesium oxide A, magnesium oxide B and a polar anti-settling agent. The ultraviolet curing sheet is characterized by convenient construction, excellent heat insulation and cold insulation properties, quick curing, environmental protection, no toxicity, convenience in packaging and transportation, easy construction and durability.

Description

technical field [0001] The invention relates to an ultraviolet light curing sheet, in particular to an ultraviolet light curing sheet used for external heat preservation and cold preservation of pipelines. 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] Heavy-duty anti-corrosion materials require coating materials to be used under harsh conditions such as chemical atmosphere and ocean, and have long-term anti-corrosion life. They can withstand acid, alkali, salt and solvent media and a certain temperature, and have low shrinkage and appropriate hardness. , toughness, wear resistance, temperature resistance, etc. The existing heavy-duty anti-corrosion materials mainly include liquid coating forms such as various epoxy anti-corrosion paints, asphalt paints, glass fiber cloth, and polyurethane anti-corrosion coat...
