Abstract

The invention relates to a preparation method of a daylighting panel, in particular to a preparation method of a weather-fastness fiber-reinforced composite material modified daylighting panel. The technical problems in the prior art are mainly solved that in the curing process of an existing daylighting panel, pollution is severe, the produced daylighting panel is poor in corrosion resistance, weather fastness and stain resistance, the whole production process is poor in automation degree, and the production cost is high. Unsaturated polyester resin, an accelerant, an assistant and fluorine-containing polyester resin are added into a stirrer according to the formula proportion for stirring, the mixture is uniformly mixed with a curing agent, glass fibers are added, a glass fiber-reinforced composite material layer is formed for covering a PVDF film, and the composite material layer and the PVDF film are conveyed into formation heating equipment for three-time formation heating. The daylighting panel is prepared from, by mass, 30%-40% of unsaturated polyester resin, 20%-30% of fluorine-containing polyester resin, 25%-35% of glass fibers, 1.0%-2.5% of a curing agent, 0.3%-1.0% of anaccelerant and 3-5% of an assistant.

Description

technical field [0001] The invention relates to a preparation method of a daylighting board, in particular to a preparation method of a weather-resistant fiber-reinforced composite material modified daylighting board. Background technique [0002] At present, a large number of ordinary daylighting panels appearing on the market are usually made of glass fiber reinforced composite materials. They are used in some large factories such as chemical factories, electroplating factories, pickling factories, leather factories, fertilizer factories, paper mills, etc. In the construction of factories and warehouses, the use of anti-corrosion and daylighting panels can not only achieve anti-corrosion and energy saving effects, but also have neat, beautiful, and environmentally friendly effects. Chinese patent discloses a flame-retardant high-toughness phenolic resin anti-corrosion lighting board and its preparation method (publication number: CN106393846A), which includes glass fiber p...
