Problems solved by technology

Although the corrugated plate made of this composite material has excellent corrosion resistance and light weight, but under high temperature conditions, the traditional FRP corrugated plate is easy to burn
After adding flame retardant to FRP corrugated plate, its mechanical properties will decrease obviously

preparation example Construction

[0036] The present invention provides the preparation steps of the bakelite corrugated board as follows:

[0037] 1. Preparation of the resin system: first blend the phenolic resin, halogen-free flame retardant, diluent, pigment, and mold release agent. The blending tank is kept at a constant temperature, and the temperature is kept at 85 degrees to keep the resin material well Fluidity will not react cross-linking.

[0038] 2. Manufacture of pre-woven parts: Weave the above-mentioned carbon fiber and glass fiber into a cylindrical shape through a loom, soak the resin material, wrap the polyester surface mat and shape it through the pre-forming mold.

[0039] 3. Curing molding: pull the above pre-woven parts into the metal mold cavity, and perform three-stage temperature-controlled curing. The temperatures of the three stages are 140-170°C, 180-240°C, and 160-190°C. At the end of the metal mold, the profile is dragged by a crawler tractor.

Embodiment 1

Abstract

The invention discloses a bakelite corrugated board made of preliminarily woven components with flow guide layers. Phenolic resin is used as matrix resin of the bakelite corrugated board. The preliminarily woven components with the flow guide layers comprise glass mats laid in a layered manner, fiber cloth for the flow guide layers and interlayer continuous fibers, the fiber cloth for the flow guide layers is positioned in middle layers of the glass mats laid in the layered manner, and the glass mats laid in the layered manner are sewn with the fiber cloth for the flow guide layers by the interlayer continuous fibers. The bakelite corrugated board has the advantages that A-grade fireproof nonmetal high-strength corrosion-resistant effects can be realized by the bakelite corrugated board, and the bakelite corrugated board can be widely applied to roofs or wall surfaces of steel structures.

Description

technical field [0001] The invention relates to the field of construction, in particular to a bakelite corrugated board made of pre-woven parts with a flow-guiding layer and a manufacturing method thereof. Background technique [0002] Due to its special shape and function, the corrugated roof structure has been widely used in various storage and other structures of industrial and civil buildings. Its short production and construction period has been generally favored by users' construction personnel. [0003] In recent years, along with the development of the national economy and the progress of science and technology, the structure and materials of large-scale industrial buildings in metallurgy, textile, machinery and other industries have undergone great changes. Traditional structural materials such as cement asbestos corrugated board, glass fiber reinforced plastic corrugated board, imitation glazed corrugated board, asbestos tile, glass, etc., can no longer meet the re...
