Problems solved by technology

[0002] At present, the production process of composite laminates is generally made of logs through rotary cutting, cutting, gluing, cold pressing, hot pressing, and trimming. The process is simple, and the produced composite laminates have high strength and long life. However, due to the relatively large amount of glue used in this production process, the environmental protection is not strong
At present, the production process of fireproof insulation boards is relatively complicated. For example, wood fireproof insulation materials generally need to be dried, flame-retardant impregnated, filled with aluminum silicate fiber blankets or rock wool boards, coated with high-temperature adhesives, pressurized, etc. A series of process steps; while steel fireproof insulation materials generally go through stamping, forming, filling fireproof materials, welding, electrostatic spraying and other steps, both production processes are more complicated and time-consuming

Abstract

The invention discloses a production process of a fire-proof and heat-preserving composite laminate. The production process includes the steps of preparing and molding the laminate, processing the laminate material, and pressurizing and curing the composite laminate. The fire-proof and heat-preserving laminate produced by the process of the application has high strength. , there is no need to fill with additional fireproof and thermal insulation materials, and the steps are simpler. In addition, the thermal conductivity of the fireproof and thermal insulation composite laminates produced by this process is small, which is 0.50W / (m K), and the thermal insulation performance is good, which can be applied It is used in the production of fireproof door frame, fireproof window frame, thermal insulation door frame, thermal insulation window frame or building exterior wall insulation board.
