Problems solved by technology

With the wider application of FRP materials in aviation, transportation, electrical appliances and other fields, the current products basically cannot reach the highest level of flame retardant effect, and its flame retardant performance has become the key reason restricting its development.
Moreover, the use of traditional halogen-based flame retardants does not meet the needs of environmental protection. The market size and application fields of halogen-based flame retardants have long ranked first among all types of flame retardants. However, when halogen-based flame retardants burn, they generate more smoke, Corrosive gases and certain toxic products will cause products to be abandoned because they fail to meet the requirements of green environmental protection. With the development of the economy, the market urgently needs products with good appearance, good flame retardant effect, low pollution, and high performance-price ratio. FRP sheet

Abstract

The invention discloses a low-shrinkage medium-temperature-cured high-efficiency flame-retardant unsaturated polyester fiberglass reinforced plastic board and a preparation method thereof. The low-shrinkage medium-temperature-cured high-efficiency flame-retardant unsaturated polyester fiberglass reinforced plastic board is prepared from the following components in parts by weight: 50-60 parts of unsaturated polyester resin, 20-30 parts of a low-shrinkage additive, 1-3 parts of an accelerant, 0.5-2 parts of an initiator, 2-5 parts of a medium-temperature curing agent, 0.1-0.5 part of a thickening agent, 8-15 parts of a novel halogen-free flame retardant, 100-130 parts of inorganic filler, 2-3 parts of a release agent and 100-150 parts of fiberglass. The curing degree, the bending strength and the flexibility of the low-shrinkage medium-temperature-cured high-efficiency flame-retardant unsaturated polyester fiberglass reinforced plastic board can be improved; residual styrene in the fiberglass reinforced plastic board is reduced.
