Problems solved by technology

[0003] Some of the raw materials used in the above patents are composites of metal, wood, etc. and resin. Although the composite materials obtained have excellent performance, the non-renewability of metal and the shortage of wood limit their development.
Composite panels mainly made of fiber and resin, with the increase of fiber content, it is difficult to achieve excellent infiltration effect
At the same time, the increase in fiber content also affects the addition of additives, such as colorants, flame retardants and anti-aging agents, which leads to limited use of composite materials outdoors
In the compounding process, the adhesive method is often used, which also increases the complexity of the process and the cost of the product

Abstract

The invention relates to a flame-retardant and weather-resistant continuous fiber-reinforced thermoplastic composite sheet and a preparation method thereof. The composite sheet includes a first weather-resistant film, a flame-retardant composite material layer and a second weather-resistant film, the first weather-resistant film and the second weather-resistant The durable film is adhered to the upper surface and the lower surface of the flame-retardant composite material layer through hot pressing and cold pressing processes; the preparation method is: laying the first weather-resistant film, the flame-retardant composite material layer and the second After the weather-resistant film, the paved material is placed in a hot press, preheated, hot-pressed, and exhausted at the same time. After the hot-pressing is completed, it is pulled to the cold-pressing machine by the crawler for cold-pressing. After the end, it is taken out and trimmed. A flame-retardant and weather-resistant fiber-reinforced thermoplastic composite sheet can be obtained. Compared with the prior art, the composite plate produced by the invention avoids the failure phenomenon of the reaction between the flame retardant and the antioxidant; the invention adopts the heat-compression composite method, which reduces the cost of gluing and the complexity of operation.
